1.0 SUMMARY
1.1 Introduction
At the request of Silver One Resources Inc. (‘Silver One’ or SVE), James A. McCrea, P. Geo. carried out an independent review of the Candelaria property in the Candelaria Mining District of Mineral and Esmeralda Counties, Nevada, U.S.A. The author conducted a property examination most recently in June 2023, reviewed available exploration results, estimated mineral resources and prepared this independent technical report. This Report was prepared in accordance with the requirements of National Instrument 43-101 and Form 43-101F1 (Standards of Disclosure for Mineral Projects) to be a comprehensive review of the exploration activities on the Property and to provide a current estimation of mineral resources on the Candelaria property.
The Property has a long history of silver production from three open pit mines and historic underground mining operations. Candelaria is currently being explored and evaluated for economic development potential.
1.2 Property Description and Ownership
The Candelaria property (the ‘Property’) is situated within the Candelaria Mining District approximately 130 miles (210 Km) southeast of the city of Reno, 55 miles southeast of the town of Hawthorne, or 20 miles (32 Km) south of the town of Mina in west-central Nevada, U.S.A. Its geographic coordinates are centred at latitude 38[o] 10’ North by longitude 118[o] 05’ West; along the county line between Mineral and Esmeralda Counties in Townships 3 and 4 North by Range 35 East.
The Candelaria property covers an area of approximately 8,293 ha (20,491 acres) and is comprised of 33 patented and 1135 unpatented federal mining claims situated on lands administered by the United States Bureau of Land Management where patented claims cover most of the immediate Northern Belle and Mount Diablo deposit areas.
Silver One Resources acquired the Candelaria property from Silver Standard Resources (“Silver Standard” or “SSR”) through an option agreement that closed in May 2023. In order to obtain its 100% interest, Silver One previously issued to SSR a total US$3,100,000 of common shares (being 10,424,374 common shares) over a three-year period from 2017 to 2020 and assumed an US$2,491,757 reclamation bond filed with the BLM. Silver One earned 100% of SSR’s interest in the property, subject to a 3% net smelter return royalty payable to Teck Resources USA on production from a certain claim group of the property and a charge of $0.01 per ton payable for waste rock dumped on certain claims as described in Section 4.1 of this report.
Silver One has posted an additional secured bond totalling USD $17,085 for the current exploration on the Property. The required permit to carry the current exploration work on the Property was secured on December 15, 2017. It is the author’s understanding that this permit is currently valid.
1.3 Accessibility and Physiography
Vehicular access to the Property is readily possible from the city of Reno via Highway I-80 east to the town of Fernley, southeast via State Highway 50 to the town of Fallon, and then south on State Highway 95 through towns of Hawthorne, Luning and Mina. The paved 6-mile property access road joins State Highway 95 approximately 15 miles south of the town of Mina and leads southwesterly to the Candelaria mine site. The driving time from Reno to the Property usually takes about 3 hours. The Property is also accessible via State Highway 95 north-northwest from

Las Vegas. Both Reno and Las Vegas have large airports with many daily domestic and international flights.
The Property is situated in the Candelaria Hills with gentle to moderate topography but with locally high relief. Elevations range from 5,500 to 6,660 feet (1676 to 2030 m) with the mine site at 6,000 feet (1,830 m) AMSL. The climate is considered arid to semi-arid, typical of Nevada’s Great Basin physiographic province with temperatures commonly ranging from summer highs in the upper 90’s to over 100[° ] Fahrenheit (36-40° C) to winter lows of below 10[°] Fahrenheit (-12° C). The reported annual precipitation averaged 4.23 inches (107.4 mm). The local vegetation is predominantly sagebrush and sparse dry-land grasses.
There are still readily available power and water sources on site and mobile office and storage facilities for Silver One’s exploration operations. There is also sufficient area within the subject claims for any possible future mining and mineral processing facilities. Nevada has a long mining history so there is a large and experienced mining work force as well as mining and exploration supplies and equipment readily available from nearby commercial centres such as Tonopah, Hawthorne, Ely and Reno.
1.4 History
High grade silver veins were discovered in the Candelaria Mountains by a party of Spaniards in 1863 and the mining district was formed the following year. The earliest producer was the Northern Belle mine which was started in 1865 and was later owned by the Northern Belle Mill and Mining Company which operated the underground mine for the next nine years. Mineralization was mined from narrow oxidized high-grade lodes averaging 50 to 60 silver ounces per ton, and ore production rates on the order of 20,000 tons per year. In 1984 the Holmes Mining Co. purchased the Northern Belle mine and Belleville processing facilities and operated under ownership of the Argentum Mining Co. The Mount Diablo mine started production in 1873 and became a major producer in 1883. Candelaria Mines Co. developed the Lucky Hill mine in 1920 and operated until 1923. From 1864 to 1954, the district produced an estimated 22 million ounces of silver mainly from Northern Belle, Mount Diablo, Lucky Hill and Potosi. No district activity is recorded from 1961 to 1967.
In the mid-1960’s several mining companies explored the Property for large tonnage, low grade silver mineralization. Among them, the partnership Congdon and Carey with Occidental Minerals Corporation (Oxymin) conducted extensive exploration drilling and defined shallow low-grade deposits at Lucky Hill and Mount Diablo that were amenable to treatment by cyanide leaching. Mine construction began in 1979 with production starting in August 1980 at a rate of 25,400 tons per day (ore and waste). The first doré bullion was poured in October 1980.
Oxymin suspended mining operation in 1982 due to depressed silver prices, and NERCO Minerals Company (NERCO) acquired Oxymin’s majority interest in the mine and restarted mining operations in early 1983. Later on 1985, Nerco acquired Congdon and Carey and began mining the Northern Belle pit. By 1987, NERCO was mining at a production rate of 5.5 million tons of ore per year from the Mount Diablo and Northern Belle pits. Mine production continued until 1989 when once again low silver prices forced suspension of all mining operations.
On 1993, Kennecott Corporation acquired Nerco and subsequently sold the mine to Kinross Gold Corporation. Kinross resumed mining operations at Northern Belle, Mt. Diablo and the Georgine pit in January 1994. Mining at Candelaria (from Northern Belle) ceased in early 1997 with leach operations continuing through early 1999. Reclamation of the Candelaria Mine has been ongoing since 1998. The mine dumps were re-contoured and seeded, and the heap leach piles were rinsed

with fresh water and seeded. Other infrastructure has been removed, and the substantial reclamation work has met all state and federal guidelines.
Silver Standard Resources Inc. (“SSR”) completed the purchase of Candelaria from Kinross Gold in 2001 for payment of cash and shares and assumption of environmental obligations.
1.5 Geological Setting
The Property is situated regionally within a zone of disrupted structure that forms the transition between the northwest-trending Sierra Nevada province to the west and the north-northeasttrending Basin and Range province to the east. The region is underlain by about 30,000 feet of structurally complex calcareous, clastic and volcanic rocks of Triassic and Jurassic age, flanked on the south by a few thousand feet of calcareous and clastic rocks of Cambrian, Ordovician and Permian age. Granitic rocks, mainly as quartz monzonitic bodies related to the composite Sierra Nevada batholith of Cretaceous age, intrude the metasedimentary and metavolcanic sequences. Cenozoic volcanic rocks, ranging in composition from basalt to rhyolitic welded tuffs, overlie the Paleozoic and Mesozoic rocks. There have been several periods of regional folding and faulting beginning in early Jurassic time accompanied by major thrusting. Cenozoic deformation consisted mainly of normal faulting and the region remains tectonically active.
The Palmetto Formation is the oldest rock unit in the Candelaria district, composed of chert, dolomite and shale of Ordovician age. This formation is unconformably overlain by sandstone of the Permian Diablo Formation which is in turn overlain by the Early Triassic Candelaria Formation comprised of sandstone, shale and a few limestone beds. A large west-trending mass of serpentine containing fragments of Candelaria shale is exposed in the immediate vicinity of the Candelaria mine site. Numerous basic dykes, older than the serpentine, and acidic dykes, younger than the serpentine, occur throughout the district. In the vicinity of the Northern Belle mine, there is a complex of sheared and brecciated metasedimentary rocks and meta dolerite. Tertiary and Quaternary volcanic rocks, consisting of basalt, dacitic tuffs and flows, rhyolite and andesitic breccia, overlie the older stratigraphy.
The pre-Tertiary rocks were repeatedly and complexly folded and faulted before the deposition of the Candelaria Formation. Post-Triassic, pre-Tertiary folding occurred along an east-west axis accompanied by shearing, faulting intrusion of peridotite and dykes, and finally by the emplacement of the mineralized, structurally-controlled veins. Later faulting in late Tertiary and early Pleistocene time resulted in the Basin and Range topography (Koschmann and Bergendahl, 1968).
1.6 Mineralization
There are several types of vein mineralization within the Candelaria district but only the fault- and fracture-controlled lode and manto-style mineralization is of economic importance. Mineralization is hosted in carbonate and clastic sedimentary rocks. Economic minerals are sparsely disseminated or in stockwork of thin quartz-sulphide veins. Deposit geometry includes Irregular bodies, locally conformable to bedding. Primary economic mineralization consists of mainly pyrite and sphalerite with lesser galena, chalcopyrite and arsenopyrite in a gangue of altered country rock, quartz and dolomite. The early high grade oxidized ores were recognizable in outcrop as limonitic and manganese-stained fault breccias with minor amounts of bindheimite, anglesite, smithsonite and cerussite.
The remaining Mount Diablo deposit peripheral to and beneath the open pit occurs primarily in the Lower Candelaria Shear as mixed oxide/sulphide transitional and sulphide-rich mineralization. The remaining Northern Belle mixed oxide/sulphide transitional and sulphide-rich mineralization

occurs peripheral to and beneath its open pit hosted by the Pick handle Gulch Thrust. The current resource below the open pits is the subject of this report.
1.7 Exploration and Drilling
Exploration conducted by Silver One since 2017 includes drilling (a total of 27,404 metres distributed in 45 sonic drill holes, 77 reverse circulation (RC) and 15 diamond drill holes, which are reported in the drilling section of this report) as well as property wide geophysics (airborne magnetometry and ground induced polarization (“IP”) surveys reported in section 9), as well as surface rock sampling and geologic mapping.
1.8 Mineral Processing and Metallurgical Testing
Prior to 2001 the Candelaria mineralization had been mined by open-pit methods and processed by heap leaching for over 20 years. During this time extensive metallurgical testing was conducted by its various operators which also includes heap leach production records.
Upon acquiring the Candelaria property in 2017, Silver One initiated metallurgical testing to evaluate possible processing techniques to recover silver from the lode, stockpiles and leach pads material. Metallurgical work was conducted by McClelland Laboratories Inc., of Sparks, NV, in 2018, and Kappes Cassiday & Associates (“KCA”) in Reno, NV, during 2018-2019 and 20222024. A summary of the metallurgical work carried out by Silver One can be found in Section 13.
Recent testing conducted by SVE suggest that Candelaria’s existing mineral resources may be processed by low-cost open-pit, cyanide heap-leach methods, similar to those used in the past. However, better silver recoveries may be achieved by using High-pressure Grinding Roller (‘HPGR’) technology, potentially improving the economics of the project.
Tests completed to date show that addition of HPGR to the crushing circuit increases the historic silver recoveries (42% and 51%) to recoveries averaging 67% of the silver and nearly 50% of the gold (oxide and mixed fresh lode ores). Cyanide leaching silver recoveries on leach pad material, also crushed with HPGR to 1.7mm, range from 29% (LP1) to 40% (LP2). These scenarios could positively impact the operational results.
Silver One is also testing other established methods including flotation combined with cyanidation, as well as new technologies which have shown the potential to improve the silver recoveries. For example, non-cyanide leach tests using Extrakt Process Solutions technology on leach pad material reports silver recoveries of 63% (LP1) and 69% (LP2). This technology is described at the end of section 13.

1. A Mineral Resource is a concentration or occurrence of solid material of economic interest in or on the Earth’s crust in such form, grade or quality and quantity that there are reasonable prospects for eventual economic extraction.
An Inferred Mineral Resource is that part of a Mineral Resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity.
An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration. An Indicated Mineral Resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit.
Geological evidence is derived from adequately detailed and reliable exploration, sampling and testing and is sufficient to assume geological and grade or quality continuity between points of observation.
An Indicated Mineral Resource has a lower level of confidence than that applying to a Measured Mineral Resource and may only be converted to a Probable Mineral Reserve.
A Measured Mineral Resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape, and physical characteristics are estimated with confidence sufficient to allow the application of

Modifying Factors to support detailed mine planning and final evaluation of the economic viability of the deposit.
Geological evidence is derived from detailed and reliable exploration, sampling and testing and is sufficient to confirm geological and grade or quality continuity between points of observation.
A Measured Mineral Resource has a higher level of confidence than that applying to either an Indicated Mineral Resource or an Inferred Mineral Resource. It may be converted to a Proven Mineral Reserve or to a Probable Mineral Reserve.
2. Mineral resources, which are not mineral reserves, do not have demonstrated economic viability. The estimate of mineral resources have no known issues and do not appear materially affected by any known environmental, permitting, legal, title, socio-political, marketing, or other relevant issues. There is no guarantee that Silver One will be successful in obtaining any or all of the requisite consents, permits or approvals, regulatory or otherwise for the project or that the project will be placed into production.
- The mineral resources in this study were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (‘CIM’), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the Standing Committee on Reserve Definitions and adopted by the CIM Council on May 10, 2014.
4. Total values may not sum correctly due to rounding.

1.10 Interpretations and Conclusions
1.10.1 Project Setting
The Project is located in an area of Nevada with moderate relief, good road access and other required infrastructure. Mining activities should be capable of being conducted year-round. There is sufficient suitable land area available within the mineral claims for any future pit expansions, leach pads, mine waste disposal, and installations such as a processing plant, and related mine infrastructure.
1.10.2 Mineral Tenure, Surface Rights, Water Rights and Royalties
Silver One acquired 100% interest in the Candelaria property in May 2023. The Property covers an area of approximately 8,293 ha (20,492 acres) and is comprised of 33 patented and 1135 unpatented federal mining claims. Several internal third-party claims are not proximal to potential future mining operations.
1.10.3 Geology and Mineralization
Silver-gold-lead-zinc mineralization at Candelaria occurs primarily along thrust- related structures including the Pickhandle thrust and the Lower Candelaria shear (“LCS”). The

mineralization is oxidized to a depth of 200 m. The deposit is considered to be an example of a disseminated Ag-Au deposit hosted within sedimentary rocks and distal to a porphyry Cu deposit. The deposit type used for exploration targeting is appropriate to the mineralization identified. The deposit remains open down-dip and along strike.
Knowledge and documentation of the deposit settings, lithologies, and structural and alteration controls on mineralization are sufficient to support the Mineral Resource estimate.
1.10.4 Exploration, Drilling and Analytical
Silver One maintains a robust QA/QC program that meets or exceeds industry standards. Only minor QAQC information is available for historic data; however, the data is believed to be reliable as it was used for successful mine exploration and development over a period of more than 20 years.
The drilling and assay data provided by Silver One is believed to be adequate for the purposes of this mineral resource estimate and the author has no reason to believe that any of the information is inaccurate. The exploration programs completed to date are considered appropriate to the style of the known mineralization within the Project area.
1.10.5 Data Verification
The QP visited the subject property and area in August of 2006, on July 9th to 11th, 2018, and again on June 9th, 2023. During the site visits for SVE, the QP completed data verification including checking drill collars, sampling leach pads and mineralized outcrops, reviewed drill core and RC cuttings, reviewed site work areas and storage, other checks as deemed appropriate.
The QP is of the opinion that these data are adequate for the purposes used in this technical report.
1.10.6 Metallurgical Test work
Silver One contracted McClelland Laboratories Inc., of Sparks, NV, in 2018 and Kappes Cassiday & Associates (“KCA”) in Reno, NV, during 2018-2019 and 2022-2024, to conduct metallurgical testing on the various type of materials (leach pads and oxidized/mixed/sulphide mineralization obtained from pits and drill core). During 2023 and 2024, the Company engaged Extrakt Process Solutions (“EPS”) to conduct non-cyanide leach tests. The best column cyanide-leach silver recoveries obtained by KCA in oxide, sulfide and mixed material crushed with HPGR to 1.7 mm are 61%, 60% and 71% respectively.
Metallurgical testing has been encouraging to date and is ongoing.
1.10.7 Mineral Resource Estimate
Mineral Resources at Candelaria are reported separately by area: Mt. Diablo and Northern Belle open-pittable; Mt. Diablo underground; leach pads and Low-Grade Stockpiles (“LGSP”). The current resources are classified as Measured, Indicated and Inferred following CIM Definition Standards (2014) and the sample database used for the estimation is adequate for the purpose used.
The Mineral Resource estimate is based on reasonable assumptions of eventual economic extraction and assuming open pit mining method for all but the small Mt. Diablo underground resource.

The following factors could affect the Mineral Resources: unknown volume of underground working; assumptions used to estimate Total Ag and Au values from historic CN soluble values; limited specific gravity data; commodity price and exchange rate assumptions; pit slope angles and other geotechnical factors; assumptions used in generating the constraining pit shell, including metal recoveries, and mining and process cost assumptions.
1.10.8 Conclusions
The exploration and development studies completed to date by Silver One support further work. This work includes further exploration and resource drilling; further metallurgical test work; environmental studies and initial permitting; and initial economic studies.
Project risk factors that may affect the mineral resource estimation include:
-
Unknown extent of historic workings at Mt. Diablo
-
Restricted number of total Ag and Au assays (FA)
-
Limited number of specific gravity measurements
-
Price and cost assumptions
-
Recovery and processing assumptions
1.10.9 Recommendations
A two-phase exploration program is recommended to evaluate its potential for further bulktonnage precious metal production and additional mineralization.
The Phase I program will update the resource, complete further metallurgy and a preliminary economic study. Total cost is estimated at US$4.06M.
The Phase II program totals US$3.46M and is not contingent on positive results from the Phase I program but will follow a thorough compilation and review of Phase I results by a qualified person.

2.0 INTRODUCTION
2.1 Introduction and Terms of Reference
At the request of Silver One Resources Inc. (‘Silver One’ or the ‘Company’ or ‘SVE’), James A. McCrea, P. Geo. carried out an independent review of the Candelaria property (the ‘Property’) in the Candelaria Mining District of Mineral and Esmeralda Counties, Nevada, U.S.A. The author conducted a property examination, reviewed available exploration results, estimated resources and prepared this independent technical report (the ‘Report’). This Report was prepared in accordance with the requirements of National Instrument 43-101 (‘NI 43-101’) and Form 43-101F1 (Standards of Disclosure for Mineral Projects) to be a comprehensive review of the exploration activities on the Property, to estimate current mineral resources in accordance with NI 43-101 and with 2014 Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards and, if warranted, to provide recommendations for future work. This Report is intended to be read in its entirety.
2.2 Site Visit
The author is an independent qualified person (‘QP’) as defined by NI 43-101 and visited the Candelaria property in August of 2006 and from July 9[th] to 11[th] , 2018 and again on June 9, 2023. The author conducted traverses across the leach pads and stockpiles, confirmed drill hole collars, and visited the existing open pits on the property. The author reviewed all aspects of the historical exploration work with Silver One personnel including results from historical exploration work, drilling operations, core storage and results, local lithological and structural features, sampling and shipping procedures, and available project documentation. The author examined core samples from the Lower Candelaria Shear. The author also collected six verification samples from the heaps, low grade stockpiles and the open pits (2018). The Property has three pastproducing open pit mines (the Lucky Hill and Mount Diablo pits merged during the last stage of production) and is currently being assessed with advanced exploration work for a mining operation. Results and photographs from the site visits accompany this report in Section 12 with data verification.

4.3 U.S. Mineral Tenure
Information in this sub-section has been compiled from the Mining Claim Procedures for Nevada Prospectors and Miners: Nevada Bureau of Mines and Geology by Papke and Davis (2002). The QP has not independently verified this information, and has relied upon the Papke and Davis report, which is in the public domain, for the data presented.
Federal (30 USC and 43 CFR) and Nevada (NRS 517) laws concerning mining claims on Federal land are based on an 1872 Federal law titled “An Act to Promote the Development of Mineral Resources of the United States.” Mining claim procedures still are based on this law, but the original scope of the law has been reduced by several legislative changes.
The Mineral Leasing Act of 1920 (30 USC Chapter 3A) provided for leasing of some non-metallic materials; and the Multiple Mineral Development Act of 1954 (30 USC Chapter 12) allowed simultaneous use of public land for mining under the mining laws and for lease operation under the mineral leasing laws. Additionally, the Multiple Surface Use Act of 1955 (30 USC 611-615) made “common variety” materials non- locatable; the Geothermal Steam Act of 1970 (30 USC Chapter 23) provided for leasing of geothermal resources; and the Federal Land Policy and Management Act of 1976 (the “BLM Organic Act,” 43 USC Chapter 35) granted the Secretary of the Interior broad authority to manage public lands. Most details regarding procedures for locating claims on Federal lands have been left to individual states, providing that state laws do not conflict with Federal laws (30 USC 28; 43 CFR 3831.1).
Mineral deposits are located either by lode or placer claims (43 CFR 3840). The locator must decide whether a lode or placer claim should be used for a given material; the decision is not always easy but is critical. A lode claim is void if used to acquire a placer deposit, and a placer claim is void if used for a lode deposit. The 1872 Federal law requires a lode claim for “veins or lodes of quartz or other rock in place” (30 USC 26; 43 CFR 3841.1), and a placer claim for all
__________ Technical Report on the Candelaria Property, Mineral and Esmeralda Counties, Nevada James A. McCrea, P.Geo. April 30, 2025
April 30, 2025

“forms of deposit, excepting veins of quartz or other rock in place” (30 USC 35). The maximum size of a lode claim is 1,500 ft in length and 600 ft in width (20.66 ac/8.36 ha.), whereas an individual or company can locate a placer claim as much as 20 ac in area.
Claims may be patented or unpatented. A patented claim is a lode or placer claim or mill site for which a patent has been issued by the Federal Government, whereas an unpatented claim means a lode or placer claim, tunnel right or mill site located under the Federal (30 USC) act, for which a patent has not been issued.

4.3.1 Candelaria Property Agreements
Silver Standard Resources Inc. (Silver Standard), now renamed SSR Mining Inc. (‘SSR’), purchased the Candelaria property from Kinross Candelaria Mining Company, an indirect wholly owned subsidiary of Kinross Gold Corporation (‘Kinross’) in May 2001. On January 16, 2017, SSR Mining Inc. entered into an option agreement with Silver One, pursuant to which Silver One was granted an option to acquire a 100% interest in the Candelaria property.
In order to obtain its 100% interest, Silver One previously issued to SSR Mining a total US$3,100,000 of common shares (being 10,424,374 common shares) over a three-year period from 2017 to 2020, and assumed a US$2,491,757 reclamation bond filed with the BLM. (Silver One NR, 2023). Silver One earned 100% of SSR’s interest in the property in May 2023, subject to a 3% net smelter return royalty payable to Teck Resources USA on production from a certain claim group of the property and a charge of $0.01 per ton payable for waste rock dumped on certain claims.
4.4 Royalties and Obligations
Certain claims are subject to royalty obligations and payments where certain claims (Jed 12-16) are subject to a 3 percent net smelter return (‘NSR’) payable to Teck Resources USA and other claims (Sesame 1-15) are subject to a charge of $0.01 per ton for waste rock dumped on these claims. The original Jed and Sesame claims were dropped in 1988 and restaked as CM claims (see Figure 4.4 to determine which CM claims are affected).
Federal unpatented lode and mill site claims are maintained by an annual payment of claims maintenance fees, which is USD $200.00 per claim and is payable to the United States Department of the Interior, Bureau of Land Management on or before September 1 each year. Failure to pay the maintenance fees on time will result in the unpatented claims being forfeited. For Assessment Year 2024, Silver One paid USD $227,000 in Federal claims maintenance fees for claims held in Silver One Resources (USA) Inc. and for claims held by the Candelaria Mining Company. Silver One, as of the effective date of this report, has paid the annual fees for 2024. (R. Diaz, pers. comm., 2025)
Patented lode claims are private land and therefore not subject to federal claim maintenance requirements but as private land, they are subject to property taxes assessed by Mineral County, Nevada, which are due annually on the third Monday of August. Silver One's property taxes totalled USD $4,424.96 for the 2024-2025 Assessment Year. Silver One, as of the effective date of this Report, has paid the county taxes.
4.5 Environmental Liabilities and Exploration Permitting
Exploration and mining activities in Nevada are subject to federal and state regulations administered by the United States Bureau of Land Management (‘BLM’) and various State and County agencies, including Nevada Department of Environmental Protection.
Currently, the mine continues to be under reclamation and operational and environmental permits are in place. Previous operator Kinross submitted the Final Permanent Closure Plan (‘Closure Plan’) to the Nevada Department of Environmental Protection (‘NDEP’) and the BLM in June 1998. The BLM Environmental Assessment report for mine closure was issued on July 21, 2000. and reclamation has continued after the acquisition of the property by SSR and then by SVE.
On August 2023 the Reclamation Permit was transferred to Silver One Resources. Silver One assumed the environmental liabilities for the Property and posted a secured bond totalling US
__________ Technical Report on the Candelaria Property, Mineral and Esmeralda Counties, Nevada James A. McCrea, P.Geo. April 30, 2025
April 30, 2025
Silver One Resources Inc.
Page 27
$2,491,757.00. The required permit to carry the current exploration work on the Property was secured on December 15, 2017 and most recently amended January 11, 2022. The Nevada Division of Minerals holds a financial guarantee posted by Silver One in the amount of US $17,085.00 to cover reclamation of approved exploration surface disturbance. The author’s understanding is that this permit is currently valid.
4.6 Environmental Considerations
To the best of the author’s knowledge, there are no environmental considerations or other significant factors or risks that may affect access, title, or the right or ability to perform exploration and development work on the Property.

5.0 ACCESSIBILITY, CLIMATE, LOCAL RESOURCES, INFRASTRUCTURE and PHYSIOGRAPHY
5.1 Accessibility
Vehicular access to the Property is readily possible from the city of Reno via State Highways 80 east to the town of Fernley, southeast via State Highway 50 to the town of Fallon, and then south on State Highway 95 through towns of Hawthorne, Luning and Mina. The paved 6-mile (10 km) property access road joins State Highway 95 approximately 15 miles (24 km) south of the town of Mina and leads southwesterly to the Candelaria mine site. The driving time from Reno to the Property usually takes about 3 hours. See Figure 4.1 and 4.2 of this report.
The Property is also accessible via State Highway 95 north-northwest from Las Vegas. Both Reno and Las Vegas have large airports with many daily domestic and international flights.
5.2 Climate and Vegetation
The climate is arid to semi-arid, typical of Nevada’s Great Basin physiographic province. Daily temperatures commonly range from summer highs in the upper 90’s to over 100[° ] Fahrenheit (3640° C) to winter lows of below 10[°] Fahrenheit (-12° C). According to Stevens (2001), the total annual precipitation, as measured at the Candelaria Mine between August 1992 and December 1998, averaged 4.23 inches (107.4 mm), and the annual lake evaporation, as measured 22 miles (35.4 km) to the northeast at the town of Mina, typically is 50 to 55 inches (127 to 140 cm). The Candelaria Hills are vegetated predominantly with sagebrush and sparse dry-land grasses.
5.3 Local Resources and Infrastructure
Reclaimed open pits, waste dumps and leach pads are evident from past mining operations. The mine and mill operation buildings were removed and their sites reclaimed by Kinross and SSR. Nevertheless, there are still readily available power and water sources on site with a modular office building. Water is sourced from the mine’s two water wells located approximately 6 km (straight line) southwest of the historic plant site (which in turn was located north and adjacent to the Northern Belle pit). Power is supplied by NVEnergy through a 25 Kv line to a substation located at the mine site.
There is sufficient area within the Property for any possible future mining and mineral processing facilities.
Nevada has a long mining history resulting in a large and experienced mining work force. All mining and exploration supplies and equipment are readily available from mining centres such as Tonopah, Hawthorne, Ely and Reno.
Mine Site infrastructure is shown in Figure 5.1.
5.4 Physiography
The Property is situated in the Candelaria Hills with gentle to moderate topography but with locally high relief. Elevations within the Property range from 5,500 to 6,660 feet (1676 to 2030 m) with the mine site at 6,000 feet (1,830 m) above mean sea level (‘AMSL’)

6.0 HISTORY
The history of the Candelaria Mining District and the mines and prospects within the Property have been well documented by public and private reports.
6.1 Early History – 1863 to 1967
Early history of Candelaria has been summarized by Knopf (1922) and Page (1959) and the history below is summarized from these sources. High grade silver veins at Candelaria were discovered by Spaniards in 1863 and the mining district was formed the same year. Growth of the camp remained limited until the successful development of the Northern Belle mine in the mid1870’s and silver production for the period 1875 to 1883 came primarily from underground development on the Northern Belle vein. Mineralization was mined from narrow high-grade oxidized lodes averaging 50 to 60 ounces per ton of silver. Due to the lack of water at Candelaria, two 20-stamp mills and roasting facilities were built and operated at Belleville, located 13 km (8 miles) to the northwest of Candelaria.
In 1882 a waterline was completed to Candelaria bringing water 43 km from the White Mountains allowing processing facilities to be constructed in the camp. A narrow-gauge railway was completed in the same year. Holmes Mining Co. purchased the Northern Belle mine and Belleville processing facilities in 1984 following a court judgement against the Northern Belle Co. for trespassing. As a result, the Holmes and Northern Belle mines then operated under ownership of the Argentum Mining Co. The Mount Diablo mine started production in 1873 and became a major producer in 1883.
The district declined after 1891 and there appears to have been little activity until 1914. A number of smaller mines, including the Georgine, Potosi, Swastika, Bi-metallic and Lucky Hill mines produced small amounts of ore into the early 1900’s. Candelaria Mines Co. developed the Lucky Hill mine in 1920 and operated until 1923. From 1864 to 1954, the district produced an estimated 22 million ounces of silver mainly from Northern Belle, Mount Diablo, Lucky Hill and Potosi. Potosi was reported to have small production from 1947 to 1954 (Page, 1959). No district activity is recorded from 1961 to 1967.
6.2 Development and Production – 1968 to 2017
Drill results from work completed by Congdon & Carey (“CoCa”) and Occidental Minerals (together as the OxyMin partnership from 1976) between 1971 and 1979 defined mineable, heapleachable low-grade Ag-Au mineralization at Lucky Hill and Mt. Diablo with a reserve of 12 Mt averaging 108 g/t Ag and 0.3 g/t Au. Mine construction began in 1979 with production starting in August 1980 at a rate of 25,400 tons per day (ore and waste). The first doré bullion was poured in October 1980.
Nerco Minerals (“Nerco”) purchased Oxymin’s majority interest in the property after operations at the mine were suspended in 1982 due to low silver prices. Mining operations at Mt. Diablo and Lucky Hill restarted in 1983. Nerco subsequently purchased CoCa’s minority interest in October 1983 to become the sole owner of the property. Mining at Northern Belle began in 1985. Combined production from Northern Belle and Mt. Diablo reached 5.5 million tons per year by 1987 with a reported reserve (Moeller, 1987) of 27 Mt averaging 50 g/t Ag and 0.19 g/t Au. Operations were again suspended in 1990 due to low silver prices.
Thomson (1990) reports that a small heap leach operation was conducted at Potosi from 1983 to 1986 by Candelaria Metals Inc.

Kennecott Corporation acquired Nerco in 1993 and subsequently sold 100% of the shares of Nerco Delamar (Delamar Mine) and Nerco Metals Inc. (Candelaria Mine and other assets) to Kinross Gold Corporation.
Kinross resumed mining operations at Northern Belle, Mt. Diablo and the Georgine pit in January 1994. During the first full year of ownership in 1994, Kinross produced 3,207,000 ounces of silver and 12,646 ounces of gold at Candelaria. Development drilling and subsequent mine planning and evaluation were conducted in 1994. Mining at Candelaria (from Northern Belle) ceased in early 1997 with leach operations continuing through early 1999. Reclamation of the Candelaria Mine has been ongoing since 1998. The mine dumps were re-contoured and seeded, and the heap leach piles were rinsed with fresh water and seeded. Other infrastructure has been removed, and the substantial reclamation work has met all state and federal guidelines.
Silver Standard Resources Inc. (“SSR”) completed the purchase of Candelaria from Kinross Gold in 2001 for payment of cash and shares and assumption of environmental obligations.
6.3 Drilling and Exploration – 1968 to 2017
The only historic surface exploration documented on the Property has been some surface rock sampling by SSR and drilling by various operators. Historic drilling is described further below.
Superior Oil, Callahan Mining and Congdon and Carey drilled 116 exploration holes totalling 8,432 m (27,664 ft) during the period 1968 to 1972 (Table 6.1). Congdon and Carey drilled an additional three holes totalling 261 m (857 ft) in 1975. The Congdon and Carey (Coca Mines) and Occidental Minerals (OxyMin) joint venture, to explore and develop Candelaria, was formed in 1976. The joint venture conducted extensive exploration and development drilling totalling more than 245 holes between 1976 and 1979.
Akright (1985) states that all drill collars were surveyed in 1978 and although not documented, collars since that date were likely surveyed by a mine surveyor. All drill holes prior to 2017 were surveyed using a local “mine grid” which was derived from the NAD27 Nevada West State Plane Coordinate system.
Few historic drill holes were apparently surveyed downhole. Nerco reported that commencing in 1990, deeper RC holes would be surveyed and twenty-three later Nerco holes and four Kinross holes have documented survey data.
Between approximately 1989 and 1992, Nerco completed 30 rotary holes (N836-838; N847-849; N855-862; N904-916; N962-963; N973-974) on the Green Nick prospect located approximately 1.5 km due east of the Mt. Diablo pit. The best silver intercept was returned from N849 with 16.8 m averaging 66.9 g/t Ag and 0.06 g/t Au.
Between 1990 and 1992, Nerco completed 34 RC holes between 35 and 125 m deep testing the Potosi silver zone (located 600 m southwest of Georgine pit) along strike and above historic workings. Thirty of the holes intersected silver mineralization with the best hole (P18) averaging 127 g/t AgSol over 7.6 m (from 3 m depth).

As part of their acquisition due diligence, in late 1999-2000, SSR drilled 10 RC holes totalling 1962.9 m in a program that twinned nine historic Mt. Diablo exploration holes located to the north of the Mount Diablo pit. This work confirmed the down-dip continuity of the mineralized zone, however, SSR silver grades were generally lower than historic grades. Neither the SSR holes nor the historic holes had downhole surveys leaving the exact location and proximity of drill intercepts in doubt.
During their due diligence, SSR also recovered 234 historic pulps (14 drill holes) and reanalysed the pulps at Chemex Labs Ltd. (now ALS) in Vancouver (sample prep in Reno) using the same CNsol assay methodology as the mine facility. Analyses were completed on the original -80 mesh pulp and a second assay run was completed on pulp samples pulverized to -150 mesh. In general, the Chemex Ag CNsol -150 pulp results are significantly higher than the original -80 mesh results with means of 81.7 ppm compared to 53.6 ppm Ag respectively. Analyses by Chemex on the original -80 pulps were comparable to the mine results.
Silver One signed an option agreement in January 2017 to purchase 100% of Candelaria from SSR. The property acquisition was completed in May 2023

7.0 GEOLOGICAL SETTING and MINERALIZATION
7.1 Regional Geology
Moeller, 1987, Foster. 1988 and Thomson, 1990 have described regional geology and key aspects of the geology, mineralization and alteration of the Candelaria Ag-Au deposits. Page, 1959 published a geologic map of the Candelaria District that shows relationships between the main lithologies that host mineralization, adjacent lithologic units, faulting, alteration and intrusive rocks. The Candelaria property is located in the eastern Candelaria Hills, Mineral and Esmeralda Counties, NV. (Watkins, 2025)
Mineral and Esmeralda counties, in the west-central part of Nevada, lie within a zone of disrupted structure that forms the transition between the northwest-trending Sierra Nevada province to the west and the north-northeast-trending Basin and Range province to the east.
West-central Nevada has been subjected to multiple episodes of thrusting, regional magmatism and subsequent normal and strike-slip faulting. Figure 7.1 illustrates the position of the Candelaria district relative to pre-Tertiary structure and stratigraphy. Five Paleozoic and Mesozoic thrust sheets, the Roberts Mountain allochthon, Golconda allochthon, Sonoma volcanic arc, Luning allochthon and Pamlico allochthon are recognized.
Permian and Triassic sediments of the Diablo and Candelaria Formations were deposited unconformably on rocks of the Roberts Mountain allochthon, which is comprised of the Palmetto Formation, a thick sequence of Ordovician chert, argillite and dolomite interleaved with slices of Devonian carbonate and calcarenite (Stanley and others, 1977). The Palmetto Fm. Is a tectonicstratigraphic equivalent of the Valmy and Vinini Formations of central Nevada.
Rocks of the Golconda allochthon, including mafic volcanics and slices of Mississippian to Early Triassic sediments, in a melange of serpentine, were thrust over the Candelaria Fm. during the lower Triassic Sonoma Orogeny. At Candelaria, the Pickhandle Gulch complex of Page (1959) represents the sole plate of the Golconda allochthon.
Candelaria is located within the east-west trending Excelsior-Coaldale block of the Walker Lane belt (Thomson, 1990). The strike of pre-Tertiary units in this area, called the Mina deflection, changes to an east-west direction from the northerly direction typical of much of Nevada.

7.2 Local and Property Geology
The geology of portions of Mineral and Esmeralda Counties, NV surrounding the Candelaria district are illustrated in Figures 7.2, to 7.5. Pre-Tertiary rock units include the Ordovician Palmetto Fm., Permian and Triassic sediments of the Diablo and Candelaria Formations, the Pickhandle Gulch complex, various rocks of the Golconda allochthon including the Middle Triassic Excelsior Fm., Upper Triassic Luning Fm. and Jurassic-Cretaceous granitic intrusives.
Basement rocks at Candelaria is comprised of thick sequence of chert-argillite-dolomite of the Ordovician Palmetto Formation which is locally interleaved with slices of Devonian limestone and calcarenite although no Devonian rocks occur in the immediate vicinity of the Candelaria property.
Marine sediments of the Permian Diablo Formation and Triassic Candelaria Formation were deposited unconformably on Palmetto Fm. and outcrop along a 19 to 24 km (12 to 15-mile) long, east-west zone roughly centered on the Candelaria deposit. The Diablo Fm. Is a thin, coarsegrained chert sandstone/conglomerate up to 10 m thick that was deposited discontinuously and/or locally eroded to form discontinuous layers on top of the underlying Palmetto Fm. Up to one kilometre of shallow to deeper water marine sediments of the Candelaria Fm. were deposited unconformably on Diablo Fm. or in sharp, angular unconformity with underlying Palmetto Fm. The lower-most Member 1 of the Candelaria Fm. is up to 60 m thick and consists of phosphatic, calcareous and locally carbonaceous mudstone and siltstone w/ thin limestone lenses. Members 2, 3 and 4 are comprised of upward coarsening siltstone, sandstone and pebbly sandstone/conglomerate deposited in deeper water environments. The thickness of Member 2, a less favorable host for mineralization, ranges from 0-300 m.
The Pickhandle Gulch complex in the Candelaria Hills, part of the Golconda allochthon, was structurally emplaced on Candelaria Formation sediments during the lower Triassic Sonoma Orogeny. The complex consists of faulted Mississippian to early Triassic sediments, metasediments and metavolcanic rocks within sheared serpentine. Mafic volcanic and pre-thrust mafic intrusive rocks occur higher in the sequence. Metasediments occur as thrust slices within mafic volcanics and as floating masses within serpentine. Up to 500 m of Pickhandle Gulch complex rocks are present in the area of the Mt. Diablo and Northern Belle pits. The Golconda thrust marks the top of the Pickhandle Gulch complex. Rocks of the Golconda allochthon in thrust contact with Candelaria Fm. in the eastern portion of the property weather to a conspicuous orange color. Volcanoclastic rocks of the Triassic Excelsior Fm., also part of the Golconda allochthon, overlie the Pickhandle Gulch complex.
Upper Triassic limestone, dolomite and shale of the Luning Formation comprise much of the Luning allochthon to the north of Candelaria.
A number of Jurassic-Cretaceous granitic stocks are present in the areas around Candelaria including Miller Mountain to the south, Columbus to the southeast, Redlich and Rock Hill east of Candelaria and Bellville, NW Bellville and Marietta to the northwest. These stocks are interpreted to be younger than the age of silver mineralization at Candelaria.
Moeller (1987) and Thomson (1990) have described intermediate to felsic composition “mine sequence” intrusions that occur as dykes and sills and cut all pre-Tertiary rocks in the Candelaria district. Thomson groups the intrusions into three phases, early aphanitic to sparsely porphyritic felsic dykes and sills that likely pre-date mineralization, medium to coarse-grained intermediate composition porphyries closely associated with mineralization and late, felsic dykes that post-date mineralization and are primarily located east of the Mt. Diablo pit. Emplacement of the dykes and

sills was focused along the east-west trending Pickhandle thrust, the Lower Candelaria shear and within Members 1 and 2 of the Candelaria Fm. Sills are up to 45 m thick and up to 1 km in length. Dykes up to 30 m in width locally cut the Palmetto and Candelaria Formations and are interpreted as feeders for the sills.
Up to 700 m of Oligocene-Miocene ash-flow tuffs, andesitic flows and pyroclastic rocks and Pliocene basalt were deposited on pre-Tertiary rocks of the Candelaria Hills and in the deep, Oligocene basin to the north. Pre-Tertiary rocks were subaerially exposed and eroded between 15 and 4 Ma. as indicated by the local deposition of Pliocene basalt directly on pre-Tertiary rocks. All Tertiary units post-date Candelaria mineralization and alteration.
Faulting in the Candelaria district is grouped into pre- and post-mineral structures. Pre-mineral thrust faulting and related shearing created favorable zones for the emplacement of mine sequence intrusives and silver mineralization. The Pickhandle thrust forms a sharp break between Candelaria Fm. sediments in the footwall and the strongly sheared and altered melange of metasediments, metavolcanics and serpentine in the hanging wall. Much of the deformation is in the lower 40 m of the thrust plate due to the incompetent nature of serpentine (Moeller, 1987), The thrust is generally parallel to bedding in sediments of the Candelaria Fm., dipping from 20 to 75 degrees to the north. The Lower Candelaria shear (‘LCS’) is a thrust-related zone of shearing within the lower part of Candelaria Fm. Member 1. Present throughout the district, the shear ranges in thickness from 1 to more than 30 m and generally dips from 20 to 60 degrees to the north. High-angle, north and northwest-striking faults that extend upward from the Lower Candelaria shear may be important in focusing mineralization in stratigraphic horizons of the Candelaria Fm. above the LCS (Warner, 1991).
Mineralized and altered pre-Tertiary rocks in the Candelaria Hills are exposed along the eastwest trending Candelaria horst, bounded on the north by the north-dipping Candelaria fault and on the south by the southeast-dipping Alpha fault. Both faults place Quaternary and Tertiary rocks against pre-Tertiary rocks of the Palmetto, Diablo Fm., Candelaria Fm. and Pickhandle Gulch complex. East of Pickhandle Gulch, the north-dipping County Line fault places Quaternary and Tertiary rocks against pre-Tertiary rock in a similar fashion. The three high-angle faults have respective dips of approximately 60 degrees. The east-northeast striking East Diablo, Bigfoot, Zeta and Delta faults are in the Mt. Diablo pit. The faults dip 50 to 80 degrees to the southeast. Post-mineral displacement of Lower Candelaria shear mineralization ranges from 15 to 100 m of downward movement in the hanging wall of the faults.

7.2.1 Mineralization
Silver-gold-lead-zinc (± Antimony ± Arsenic) mineralization at Candelaria occurs primarily along thrust- related structures including the Pickhandle thrust and the Lower Candelaria shear. Silver One geochemical analyses of drill core and cuttings show a close association between Ag-Au mineralization and cadmium. According to Moeller (1987), 65 percent of open pit mineralization is in the lower half of Member 1 of the Candelaria Fm. deformed by the Lower Candelaria shear, approximately 25 percent are controlled by the Pickhandle thrust and parallel structures with the remaining 10 percent hosted by mine sequence intrusives and their contact zones with preTertiary wall rocks. Bulk-mineable mineralized zones are primarily tabular, sheet-like bodies that dip 20-75 degrees to the north and are generally parallel to stratigraphy or controlling faults. Historically, the Mt. Diablo, Northern Belle and Lucky Hill pits comprised the bulk of economically mineable mineralization. Original, high-grade veins mined in the late 1800’s and early 1900’s occur within this same area. The smaller Georgine pit is located 1.5 km west of Northern Belle (Fig 7.5). Age dates reported by Moeller (1987) and Thomson (1990), referencing Silberman (1975) include 126 Ma on hydrothermal sericite and measurements of 127 Ma. and 131 Ma on a sericitized porphyry dyke. Subsequent weathering and oxidation of the mineralized zone occurred during two distinct periods of time. The first was during a late Cretaceous to early Tertiary erosional event, after which the paleo-erosional surface was capped by younger volcanic rocks. The second followed the Tertiary to Recent erosional period during which the mineralized zones were again exposed at the surface. Partial to complete oxidation of the deposits extends to depths of 200 m.
Mineralization in the Lower Candelaria shear is best developed in the Mt. Diablo pit area where boundaries of higher-grade mineralization closely match the limits of the shear zone. . In some areas, the shear zone is at the base on Member 1 of the Candelaria Formation where deformation was focused immediately above the massive Diablo Formation. In other areas it is as much as 20 m above the base of Member 1, but is always lower than the upper grit, a cherty fragmental marker bed similar to the Diablo Fm. The shear is thickest, up to 35 m, where the Pickhandle thrust is within 100 m of Candelaria Member 1 sediments. Lower grade mineralization extends 50 to 150 m upward from the top of the Lower Candelaria Shear into upper Member 1 sediments, mine sequence intrusives and rocks of the Pickhandle Gulch complex. Within and marginal to the Lower Candelaria Shear zone are irregular and discontinuous high-grade lenses and shoots of more massive iron and manganese-iron oxides with dolomite and quartz gangue. These high-grade zones were the focus of early underground mining and consisted of lenses and shoots <1 m to 3 m (2 to 10 feet) thick, with continuity along strike of up to 30 m, and dip extents of several hundred metres. Many of the high-grade lenses may be the due to the replacement of narrow limestone beds that occur in Member 1 of the Candelaria Formation (Thomson, 1990).
Oxidized LCS is characterized by sheared, broken and rotated blocks of strongly sericitized Candelaria Fm. sediments, mine sequence intrusives, iron oxides of hematite, limonite and jarosite, manganese oxides, oxides of lead, zinc and antimony and local preserved sulphides of pyrite and sphalerite. Mineralization is partially or completely oxidized to a depth of 200 m. Silver to gold ratios average 400:1.
Unoxidized LCS is comprised of quartz and dolomite stockwork veining in sheared, broken and rotated blocks of carbonaceous Candelaria Fm. sediments, mine sequence intrusives and lenses of pyrite and sphalerite sulphide mineralization. Pyrite is by far the dominant sulphide. Jamesonite, tetrahedrite, stibnite and acanthite occur as inclusions in pyrite and/or quartz.

In the Northern Belle and Lucky Hill pits, mineralization is best developed along the Pickhandle thrust. At Northern Belle, multiple sub-parallel zones of mineralization occur in rocks of the Pickhandle Gulch complex and at the thrust contact between the Pickhandle Gulch complex and underlying, sheared Candelaria Fm. sediments and mine sequence intrusives. Abundant quartz veining is not present at Northern Belle. Although Moeller (1987) and Thomson (1990) report that the LCS at Northern Belle and Lucky Hill is generally less than 3 m (10 feet), drill hole logs describe thicker intervals of mineralization in lower Candelaria Fm. sediments that are similar to LCS. Sills up to 50 m thick emplaced along the Pickhandle thrust are often mineralized. Lower grade mineralization extends 50 to 75 m below the Pickhandle thrust into Candelaria Fm. and mine sequence intrusives in the Northern Belle pit, Mineralization at Lucky Hill occurs as relatively narrow zones along the Pickhandle thrust.
Depth of oxidation at Northern Belle ranges from 100 m east of the Northern Belle shaft (located near east margin of pit) to 200 m west of the shaft. The increased depth of oxidation west of the shaft is interpreted to be due to greater structural preparation related to the position of the Pickhandle thrust and high-angle northwest striking faults within the pit relative to the location of the shaft.
Silver grades from the open pit operations have typically ranged from 70 to 2275 g/t Ag (2 to 8 oz/T), with local areas of higher grade in excess of 1,700 g/t. Chavez and Shrestha (1987) report that 95 percent of total silver occurs as native silver and cerargyrite. Native silver rims and possibly replaces cerargyrite (Chavez and Shrestha, 1988). Thomson (1990) states that the remaining silver probably occurs in rare phases such as pyrargyrite (ruby silver). Foster (1988) observed inclusions of arsenopyrite, gersdorfite, jamesonite, tetrahedrite, tennantite and pyrrhotite in pyrites from Lucky Hill
District-scale metal zoning, possibly unrelated to lithology, was recognized by Page (1959). Ag:Au and Zn:Pb ratios are generally higher at Mt. Diablo and eastward. In the western part of the district, Pb, Au and Sb are relatively more abundant. Horlocker (1981) documented the westward increase in Pb:Zn across the Mt. Diablo - Lucky Hill area. Higher Cu values, evidenced in part by coppertourmaline veins, occur west of the Northern Belle pit.
Figure 7.7 illustrates important geologic settings and distribution of Ag mineralization in the Mt. Diablo, Northern Belle and Lucky Hill pits. Northern Belle is interpreted to be a northerly or westerly depth extension of Lucky Hill mineralization. According to Moeller (1987), reconstruction of Candelaria mineral occurrences along post-mineral faults indicates the main orebodies were once contiguous. The mineralized zones comprise a continuously mineralized area 4.6 km along strike with a minimum down dip extent of 1200 m, all within a structural - stratigraphic package no more than 120 m thick.

8.0 DEPOSIT TYPES
A number of previous workers have contributed important descriptions and interpretations of the geology and mineral deposits of the Candelaria district including Burgess (1922), Knopf (1922), Page (1959), Moeller (1987), Foster (1988) and Thomson (1990). Moeller defined Candelaria as an epigenetic, structurally controlled Ag-Pb-Zn deposit genetically related to a suite of pre- to synmineralization Mesozoic intrusives. Thomson places the age of these mine-sequence intrusives ranging from Mid-Jurassic (early Type Ie(o) felsite) to Early Cretaceous Type II porphyries and to Mid-Cretaceous Type Il felsite. Foster proposed that Candelaria is the upper levels of a granodiorite molybdenite system with hydrothermal fluids focused in structurally prepared carbonate-bearing and carbonate-altered rocks of the Candelaria Fm. and Pickhandle Gulch complex.
Cox (1990) included Candelaria in their descriptive model of disseminated Ag-Au deposits where disseminated Ag and Au mainly occur in sedimentary rocks distal to porphyry Cu, skarns and polymetallic veins. Typical deposits include Taylor, Star Pointer, Cove and White Pine (NV); Tecoma (UT) and Vekol, Tombstone and Hardshell (AZ). The model is similar to sediment-hosted Au but is distinguished by significantly higher Ag grades and higher geochemical background values. Primary commodities are silver and gold. Antimony occurs locally. Associated deposit types can include Cu porphyry, Cu skarn, Pb-Zn skarn, Au skarn, polymetallic veins, polymetallic replacement and replacement Mn deposits.

Effect of Weathering: Leaching and re-deposition of Ag as cerargyrite forms bonanza deposits (White Pine, NV; Vekol, AZ.
-
Geochemical Signatures: Ag ± Au ± Pb ± Mn ± Zn ± Cu ± Sb ± As ± Hg ±Te; Mn introduced at Cove, Candelaria and Star Pointer. Ag: Au ratios are highly variable: Candelaria 400:1; Taylor 143:1; Tecoma, 60:1; Purisma Concepción, 51:1; Hilltop, <2:1.
Structural preparation, carbonate-bearing sediments (Member 1 - Candelaria Fm.) or carbonate alteration (Pickhandle Gulch complex) and intrusion of intermediate to felsic composition dykes and sills provided the primary controls on mineralization. Sheared rocks along and adjacent to the Pickhandle thrust and Lower Candelaria shear hosted as much as 90 percent of Ag-Au mineralization produced from historic open pit operations at Candelaria. The Pickhandle thrust and the Lower Candelaria shear are largely conformable to bedding in Candelaria Fm. sediments. Calcareous and carbonate-bearing sediments and carbonate altered rock within these structures were favourable horizons for replacement-style mineralization. The remaining 10 percent of mineralization was hosted in mine sequence intrusives interpreted to be genetically closely related to mineralization.
Oxide mineralization is characterized by strong quartz-sericite alteration, iron oxides of hematite, limonite and jarosite, manganese oxides, oxides of lead, zinc and antimony and local preserved sulphides of predominantly pyrite and sphalerite. Unoxidized mineralization is comprised of quartz-dolomite-sulphide stockwork veining and lenses of pyrite and sphalerite. Pyrite is by far the dominant sulphide. Jamesonite, tetrahedrite, stibnite and acanthite occur as inclusions in pyrite and/or quartz.
Native silver and cerargyrite reportedly comprise 95 percent of Ag mineralization at Candelaria. Native silver rims and possibly replaces cerargyrite (Chavez and Shrestha, 1988). Thomson (1990) states that the remaining Ag probably occurs in rare phases such as pyrargyrite (ruby silver). Foster (1988) observed inclusions of arsenopyrite, gersdorfite, jamesonite, tetrahedrite, tennantite and pyrrhotite in pyrites from Lucky Hill.
The primary geochemical signature at Candelaria is Ag-Au-Pb-Zn (± Sb ± As ± Cd). Copper is present but is a minor constituent in Ag mineralization. The Ag-Au ratio averages 400:1 but ranges from 700:1 in mineralization hosted by the Lower Candelaria shear to 200:1 in the mineralized portions of the Pickhandle Gulch complex.
Occurrences of coarse chalcopyrite in with sphalerite, galena and pyrite in skarn, anomalous PbZn mineralization in skarn and anomalous, disseminated Cu-As mineralization in felsic and porphyritic intrusives in the western part of the district support the proposed model.
Regional exploration should focus on the east-west trending Candelaria basin where it is overthrust by the Golconda allochthon. Triassic Candelaria Fm. and Permian Diablo Fm. outcrop along a strike length of 22 km. Geological mapping of Mineral County, NV compiled by Ross (1961) shows an outcrop of Candelaria Fm. that extends the strike length of potentially favorable host sediments an additional 13 km to the west. Rocks of the Pickhandle Gulch complex outcrop along a strike length of 11 km in the Candelaria Hills. However, the leading edge of the east-west trending portion of the Golconda allochthon extends for 130 km from the Sierra Nevada to the Mina deflection. Exploration of this area is warranted based on the possible presence of buried, mineralized Candelaria Fm. beneath the thrust plate, particularly where Jurassic-Cretaceous intrusives are also present.

9.0 EXPLORATION
Exploration conducted by previous operators is summarized in the History section of this report. The exploration conducted by Silver One since 2017 includes drilling (45 sonic drill holes, 77 reverse circulation (RC) and 15 diamond drill holes (reported in the drilling section of this report), Airborne magnetometry and ground induced polarization (“IP”) geophysical surveys (reported below), as well as surface rock sampling and geologic mapping.
9.1 Magnetometry
In August 2019 Silver One Resources Inc. contracted SHA Geophysics Ltd. to carry out Heli-GT helicopter-towed aeromagnetic three-axis gradient surveys over its Candelaria project. Equipment and crew mobilized to El Aero Helicopters in Carson City Nevada on September 27[th] , 2019. During a three-day period between September 28[th] - 30[th] , 2019 a total of 809 km of data was collected over the project area.
The survey was conducted in north-south oriented lines, with a 100-meter spacing and 40-meter terrain clearance (sensors) and east-west oriented control lines spaced 1,800 meters. All of the geophysical and ancillary equipment is housed in a towed bird designed by SHA Geophysics Ltd., manufactured from non-magnetic FRP. The Heli-GT bird is towed 25 m below the helicopter (image below).
==> picture [165 x 165] intentionally omitted <==
Four Scintrex CS-3 cesium sensors are arranged in an orthogonal array with 3 m sensor separation from the nose sensor to those at the end of each arm of the bird. The Heli-GT bird was flown at a nominal altitude of 30m.
The geophysical survey was very successful in identifying new targets not previously identified as well as in mapping structures that may be important controls to the silver mineralization. Preliminary results illustrate that mineralized structures present at Diablo, Northern Belle and Georgine, continue 4 km farther to the east and west of the Diablo and Georgine pits respectively. Results also reveal a large magnetic high with a geophysical signature consistent with iron-oxide, copper-gold (“IOCG”) deposits. This feature constitutes a major target 5 km long and 1.5 km wide represented by the red area north of Georgine pit (Figure 9.1).
Further data processing using magnetic vector inversion (“MVI”) reveals a series of anomalies interpreted as apophyses (near-surface extensions to potentially mineralized, larger intrusive bodies at depth) and alteration possibly associated with porphyry-style mineralized systems.

Depth of these anomalies are interpreted by the geophysical metal factor (“MF”) and MVI data to vary from near surface (100 m) to over 1,000 meters. These anomalies also form part of the target anomalies shown in Figure 9.2. MVI anomalies were followed up with IP surveys that cover the entire property.
9.2 Induced Polarization (“IP”) surveys
Induced Polarization/Resistivity surveys were conducted at the Candelaria Project by Zonge International in three phases during 2020 to 2022. A total of 75,200 meters were surveyed in 13 lines with an average spacing between lines of 1km and dipole length (spacing) of 300 m. The survey was conducted in north-south oriented lines, except for line 5 oriented at a 40 degrees azimuth, using a 30 kva transmitter. Line locations are shown in Figure 9.2.
An IP survey revealed strong IP and metal factor (MF) anomalies, (low resistivity and high chargeability) around the Candelaria historical resource area. MF anomalies persist down-dip from the mineralized pits, suggesting continuity of mixed (oxide-sulphide) and sulphide mineralization beyond the limits of the historic Mount Diablo and Northern Belle resource areas. Similar MF values continue east and west from the Northern Belle and Diablo pits to the Green Nick prospect to the east, to the area south of the Georgine pit, and to the Red Hill showing to the west of the pits (see Figure 9.3).
9.3 Rock Sampling
Silver One has collected 1,157 surface rock samples on the Candelaria property which is in addition to 204 samples collected by SSR prior to 2017. Most samples are selected grabs and chips and analytical details are given in Section 11.2.5. Samples were collected along strike up to 4.3 km west of the pits and up to 3.7 km to the east. Most anomalous results overlie Candelaria Fm., Palmetto Fm., Pickhandle Fm. and minor mine sequence intrusive rocks.
The results reveal several clusters of high silver, gold, copper and other trace elements which delineate significant anomalies. Lead and antimony are closely associated with silver mineralization at surface in the pit areas where bindheimite, a lead-antimony oxide, occurs at Northern Belle, Lucky Hill and the Potosi Mine (Knopf, 1922; Page, 1959). The Pb-Sb association provides a useful surface geochemical signature in this deeply oxidized environment where other metals such as Zn and Cu may be leached. Sample distribution and geochemistry for Ag, Pb and Sb are shown in Figure 9.4.
Around the historic open pits, the surface assays have expanded the footprint of the mineralization at least 2 km east of the Mt. Diablo pit, 1 km west of the and 500 m west of Georgine pit. Other relevant targets identified to date include the Red Hill target (where four rock chip samples report copper grades between 0.7% and 1.5% over widths between 1 to 1.5 meters), the Green Nick target (where multiple assays from select rock chip samples report highly anomalous gold between 0.20 to 0.88 g/t, silver between 84 to 585 g/t, and copper between 397 to 1,526 ppm), and the Georgine target located south of the Georgine pit (with gold values between 0.55 to 2.78 g/t, silver between 215 to 557 g/t and copper between 0.1 to 4.5%).

10.0 DRILLING
The Candelaria property has seen four drill programs carried out by Silver One since 2017. Silver One completed sonic drilling of the heaps and low-grade stockpiles and RC and diamond drilling in the Mount Diablo and Northern Belle areas.
10.1 2017 Sonic Drill Program
Silver One completed a sonic drill program in November and December 2017 on the Candelaria property. The program involved drilling holes on the leach pads and low-grade stockpiles including: 17 holes on Leach Pad #1 (“LP1”), 10 holes on Leach Pad #2 (“LP2”), 16 holes on the stockpiles and two holes on dump material left over from previous operations. A total of 1112.1 m was drilled in 45 vertical holes. Drilling was conducted on a 200-metre spacing rectangular grid with a hole in the center (providing a nominal spacing of 141 metres to 200 metres between drill holes) on LP1, a 100-metre grid on LP2, and a 50 to 75 metre spacing grid on the stockpiles.
The Sonic drilling program was carried out using a Boart Longyear Sonic Drill. The drill rig was track mounted and used 3 m rods with a 20.3 cm (8 inch) outside diameter and a core tube with a 15.25 cm (6 inch) inside diameter. Sonic drilling core consists of typical heap material including varying amounts of fines and crushed rock with size fractions, generally ranging from 0.5 inches to 4 inches. These were placed into 6” (15.25 cm) diameter plastic bags and sealed with plastic ties at 1 to 2 feet long sections at the rig prior to transporting to the secure sampling facility for logging and sampling.
Detailed descriptions of the sonic drill core were carried out under the supervision of a Silver One’s senior geologist. The logging and sampling were carried out on-site in a dedicated core logging/storing facility. Drill log data were recorded onto paper logs that were later digitized. The 2017 sonic drill hole collars are shown in Figure 10.1 with the collars from 1992 sonic drill holes by NERCO. Drill collars from the 2017 sonic drilling are listed in Table 10.1 (NAD83 11N). Results of the 2017 sonic drilling are listed in Table 10.2.
There are no known drilling, sampling or recovery factors that could materially impact the accuracy and reliability of these results. The drilling was performed on heap leach pads with vertical holes so the intervals in Table 10.2 are true widths for the material laying on the leach pad. The crushed material on the leach pads has no orientation in terms of mineralization. There were no significantly higher-grade intervals noted in the drill results.

10.2 2019-2022 RC and Core Programs
Silver One completed three drill programs on the Candelaria property where the first was a diamond drill program commencing in December 2019 followed by two phases of RC drilling in 2021 and another RC drill program in January of 2022. The Silver One’s drill programs involved drilling holes on Mount Diablo above and down dip from the open pit, down dip from the Northern Belle pit, as well as on the Georgine and Green Nick areas (Fig 10.2 to 10.4).
Nine HQ and PQ core holes (holes 46-54) were drilled in 2019 to 2020 for 2,860.57 meters of PQ and HQ core. The program in 2021 reported 14,494.95 m of RC drilling (holes 55-100) with 293.4 m of diamond drilling at the bottom of hole 81 and the 2022 program reported 7,632.26 m (holes 101-131). Between April and August 2022, a total of 1,010.74 meters of HQ and NQ diamond drill holes, distributed in six holes were completed for metallurgical testing (holes 132-137). In total 26,292 metres were drilled in 92 drill holes (R. Diaz, pers. comm.2025).
The 2019 – 2020 diamond drilling program was carried out using an Atlas Copco CS14 drill. The drill rig was track mounted and used 3 m PQ and HQ rods with a 3 m core tube. Core was placed in boxes at the rig prior to transporting to the secure sampling facility for logging and sampling. RC Samples were collected at the drill and logged at the sampling facility. 2019 to 2022 drill hole collars are listed in Table 10.3 and shown on Figures 10.2 to 10.4. A summary of significant analytical results is shown in Tables 10.4 and 10.5. Collar location coordinates are in UTM NAD83 zone 11N. Elevations are reported in metres. The drill holes are marked in the field with a cement plate and were surveyed by Desert Engineering.
There are no known drilling, sampling and recovery factors that could materially impact the accuracy and reliability of results.

11.0 SAMPLE PREPARATION, ANALYSES AND SECURITY
Historically, silver grades used in the resource and reserve estimates and production records at Candelaria have been based on soluble (leachable) silver grades (AgCN) and gold grades (AuCN) obtained from hot cyanide leach methods, since the previous open-pit operation’s focus for processing was on heap leaching the silver and gold (Stevens, 2001). SSR and Silver One assayed all samples for both cyanide soluble and total gold and silver.
11.1 Sample Preparation and Analyses - Historical
11.1.1 Superior/Callahan/Congdon & Carey (1968 – 1975)
Sample and analytical procedures prior to 1976 are not documented. Fire assay (FA) results for Ag and selected samples for FA Au exist, however, the detailed methodology and laboratory are not known. Histogram and probability plots of AgCN results suggest the cyanide soluble (‘CNsol’) methodology was different than that used by the mine.
11.1.2 OxyMin - Nerco – Kinross (1976 - 1999)
RC and rotary drilling, sampling and analytical procedures used by Nerco and Kinross have been summarized by Nerco (1991) and Stevens (2001).
Sampling procedures at the mine were:
-
Rotary and RC holes were sampled on 5-foot intervals
-
Cuttings split at site with an approximately 9 kg sample collected in cloth sacks for analysis
-
Cuttings air dried at the mine laboratory
-
A 1 kg split was oven dried at 150° C and then crushed to -¼ inch
-
A 300 g split was pulverized to -80 mesh and this pulp stored in a wire-closure kraft envelope
The cyanide soluble Ag-Au procedure used at the mine is summarized in Table 11.1.
The OxyMin partnership (Congdon & Carey and Occidental) was established in 1976 during mine development. The partnership established a temporary laboratory in Hawthorne during development and it seems likely that during this period (1977 to 1980) methodologies were similar to those used later at the mine.

11.1.3 Silver Standard (1999 – 2000)
Silver Standard's drill hole samples were shipped to Chemex Labs (now ALS) in Reno NV. for drying and sample prep. Pulp samples from Reno were shipped to Chemex Labs in North Vancouver B.C. for tri-acid digestion, 22 element ICP-AES analysis. Gold analyses were completed by Fire Assay Fusion / Atomic Absorption with silver overlimits by Fire Assay Fusion / Gravimetric analysis. Cyanide leachable silver was analyzed following the mine methodology (Table 11.1) but with -150 mesh pulp (instead of -80 mesh mine standard).
11.2 Sample Preparation and Analyses – Silver One
11.2.1 Sonic Drilling Sampling (2017)
Sample procedures for the sonic drilling campaign on the leach pads and low-grade stockpiles have been reported in McCrea (2020) and are summarized below from this report.
-
The bags arriving from the drill were first individually weighed and organized by depth.
-
Bags were measured to estimate recovery; any discrepancies between the marker ties and measured core length were recorded at this stage. Bags were then cut open and photographed prior to logging or sampling.
-
The bags were marked up for sampling and then closed and laid in a separate room for partial drying prior to sampling.
-
Holes were sampled in their entirety with individual samples range from 0.67 metres to 3.05 metres, all being true widths. Samples were spit in a Jones splitter at typically 1/8 of the sample interval resulting sample weight between 1 and 8.5 kg per sample (5 kg average).
-
Split samples were transferred into transparent vinyl sample bags that were sequentially numbered to match the sample number sequences in the sample tag booklets used by the core-logging geologist. The remainder of the sample was properly bagged, labeled and stored in the storage facility, on site.
-
the sealed samples were packed in properly labeled rice bags, which were placed on pallets, before being hand-delivered by Silver One personnel to the Fedex representative in charge of Skyline’s account in Reno Nevada who shipped the samples to Skyline Labs in Tucson, Arizona.

There is no relationship between Silver One and Skyline Labs other then the procurement of analytical services.
11.2.2 Diamond Drill Core Sampling (2019 – 2020)
Candelaria core handling was as follows:
-
Core boxes are delivered to the logging area by drill crews at the end of each shift.
-
Drill depths on box tops, box ends and core blocks are converted from feet to metres.
-
Box tops and Box ends are labeled with Drill Hole Number, From – To, Depth and Box Number
-
Core is washed, rotated in the box to match up adjacent pieces of core where possible and marked at 2 m intervals.
-
Core is photographed.
-
Core is logged for RQD by geologist or core tech.
-
Mag susceptibility measurements recorded by geologist or core tech on 2 m intervals by averaging 4 – 6 individual measurements per 2 m.
-
Core is logged for lithology, mineralization, veining, alteration and structure. All logging and core measurements are recorded on paper logs and later entered directly into Datamine dhlogger or in Excel spreadsheets for importing into dhlogger.
-
Assay sample intervals are marked on core, generally at 2 m intervals with breaks at lithologic contacts at the discretion of the geologist.
-
Intervals selected for assay are sawed with half core sent for assay and half core saved in box.
-
Boxes of sampled core are stored on racks in locked, shipping containers located on the property.
Core samples were assayed by American Assay Laboratories (“AAL” in Sparks, NV, USA. (IAS accredited Laboratory, ISO/IEC 17025:2017. Samples were analysed by 25 element ICP-OES with silver over limits by Fire Assay Fusion / Gravimetric and for gold by Fire Assay Fusion / ICP finish analysis. AAL also inserts blanks, standards and includes duplicate analyses to ensure proper sample preparation and equipment calibration.
There is no relationship between Silver One and American Assay Laboratories other then the procurement of analytical services.

11.2.3 Diamond Drill Core Met Sampling (2022)
In 2022, SVE completed six core holes totalling 1,010.74 m for the purposes of obtaining representative mineralized samples for metallurgical testing. All holes were located within the Mount Diablo pit.
Candelaria met core handling was as follows:
-
Core boxes are delivered to the logging area by drill crews at the end of each shift.
-
Drill depths on box tops, box ends and core blocks are converted from feet to metres.
-
Box tops and Box ends are labeled with Drill Hole Number, From – To, Depth and Box Number
-
Core is washed, rotated in the box to match up adjacent pieces of core where possible and marked at 2 m intervals.
-
Core is photographed.
-
Core is logged for RQD by geologist or core tech.
-
Mag susceptibility measurements recorded by geologist or core tech on 2 m intervals by averaging 4 – 6 individual measurements per 2 m.
-
Core is logged for lithology, mineralization, veining, alteration and structure. All logging and core measurements are recorded on paper logs and later entered directly into Datamine dhlogger or in Excel spreadsheets for importing into dhlogger.
-
100% of mineralized zones in the six metallurgical core holes were composited to create a single sample for each drill hole and submitted for metallurgical testing.
-
Boxes of sampled core are stored on racks in locked, shipping containers located on the property.
11.2.4 RC Cuttings Sampling (2019 – 2022)
RC rig sampling was conducted at the drill rig by an SVE geologist and followed the procedures detailed below.
-
RC samples are collected at the drill; all RC drilling is conducted with air and/or water as the drilling medium.
-
Assay samples consist of an approximate quarter-split of all cuttings and water returned from each 5 ft interval and are collected in an 18" x 24" MicroPor cloth sample bag, resulting in 6 kg to 10 kg samples when dry.
-
Samples for logging of each 5-ft interval are washed at the drill site and saved in chip trays holding 100 ft (20 compartments) of chips; larger logging samples for each 5-ft interval are saved in 4x6 in kraft bags.
-
The remaining 3/4 split of all cuttings are saved in 24x36 in woven, polypropylene bags and stored on the property for possible future use.
-
Assay duplicates are collected at the drill by using approximate 1/8 splits for both the assay sample and duplicate.
-
Samples are allowed to drain at the drill site and are transported to the secure core and sample facility by Company employees each day. Samples are then allowed to air dry in a fenced and locked facility prior to being submitted to the laboratory for analysis
All RC samples were assayed by American Assay Laboratories (“AAL”) in Sparks, NV, USA (ISO accredited Laboratory, ISO/IEC 17025:2017). Samples were analyzed for thirty-five elements by ICP-MS. Gold and silver were analyzed by cyanide extraction, FA with ICP finish, samples over 100 g/t Ag were analyzed by gravimetric methods. Over limit Cu, Pb and Zn were analyzed by ore-grade volumetric analysis.

11.2.5 Surface Rock Sampling
Grab and chip samples collected by Silver One varied from 1 kg to 5 kg and were assayed by American Assay Laboratories (“AAL”) in Sparks, NV, USA (ISO accredited Laboratory, ISO/IEC 17025:2017). Samples were analyzed for thirty-seven elements by ICP-MS. Over limit copper, lead and zinc were analyzed by ore-grade volumetric analysis. Silver One inserted commercial standard and blanks in the sample batches. AAL inserts blanks, standards and includes duplicate analyses to ensure proper sample preparation and equipment calibration.
11.3 Assay Quality Control (“QA/QC”)
The current quality control program used at Candelaria follows industry standard best practices. SVE QA/QC results for RC drilling have been reported in several SVE internal reports, including for 2019 to 2021 drilling: Shenk, 2022; and for 2022 drilling: Cann, 2022 and are summarized below. QA/QC data for diamond drilling has not been reviewed because of the limited core drilling and sampling. The emphasis below is on RC results which comprise the majority of recent resource drilling.
Limited information is available for QA/QC practices used by Nerco (and likely Kinross) and these are summarized below. Little to no information is available for practices – if any- prior to 1976. An OxyMin report by Haxby and Coster (1978) reports a statistical study on the C and X series holes. The 1999-2000 RC drilling program by SSR does not report QC protocols (Kemp, 2000), however, the work likely met or exceeded industry best practices at the time.
11.3.1 QA/QC – Historical 1990 Nerco Drilling
Limited QA/QC data presented in (Nerco (1991) were reviewed and summarized in an internal SVE report by Cann (2024). The results are summarized in Table 11.2 below taken from that report. Historic QA/QC protocols were conducted according to accepted industry standards. Silver One geologists’ analysis found that the CV%AVE for both Ag and Au is generally near or above acceptable or recommended values especially given the coarse pulps used by the mine.

11.3.2.4 Field Blanks
The field blanks were also inserted into the sample stream on a 1 in 20 basis and Silver One submitted 46 blanks for analyses during the program. The field blanks were locally sourced silica material that was purchased from Home Depot. Six samples of the blank material were submitted to ALS Global and returned values below detection limit. A plot of the field blanks for silver is shown in Figure 11-2. Some blanks show small traces of mineralization and three contaminated blanks were observed.

11.3.3 Silver One 2019-2022 RC Drilling
The QA/QC program for the 2019-2022 drilling at Candelaria included the submission of Certified Reference Materials, blanks, field cutting duplicates, as well as the insertion of crushed duplicates and pulp duplicates at random intervals. QA/QC results for the 2019-2022 drilling are summarized in Shenk (2023). Certified Standards were inserted at a rate of one standard for every 17 samples (6% of total) and one blank for every 20 samples (5% of total). Core, pulp and crush duplicates combined were inserted at a rate of one duplicate per every 20 samples (5% of total). The standards used in the 2019-2022 Candelaria drilling program range in grade from 5.88 g/t Ag to 493.0 g/t Ag and were commercially sourced. Field core duplicates were obtained from quartered core, crush and 'pulp' duplicates were taken from coarse reject material or pulverized splits respectively. Blank material was sourced as sand from a Reno supply store or were Tertiary basalt chips sourced from site.
11.3.3.1 Certified Reference Material
Silver One used 10 certified reference materials (‘CRM’) with 5 CRMs being used from 2019 to 2021 and 5 used in 2022. The CRMs were purchased from Analytical Solutions Ltd., Canada and prepared by Ore Research and Exploration Pty Ltd. of Australia (OREAS) and were provided to Silver One in ~60 g pouches. The CRMs are listed in Table 11.4.

Several sequential plots of returned Ag and Au values are shown below in Figure 11.3 to Figure 11.6.
All commercial standards used in the 2019 to 2022 RC drilling at Candelaria behaved well and - with the exception of a mislabelled, possibly blank sample – did not show any laboratory issues. The average Ag and Au values returned from the standards show small biases compared to the certified values that generally range from ±2%. The strongest bias was an average of -4.8% ppm Ag for OREAS 680.

11.3.3.2 Field, Crush and Pulp Duplicates
During 2019 to 2022 Candelaria RC drilling programs duplicate samples originating from three different sample handling points were submitted into the final sample assay stream. These were:
-
Field Duplicates – even split of the original RC chip sample as collected at the rig. Split samples were prepared by Silver One personnel using a riffle splitter and dried drill samples. Original and duplicate RC chip samples vary in weight from 0.3 kg to 7.2 kg. Field duplicates show field, preparation and analytical precision (or error).
-
Coarse Crush Duplicates – duplicate coarse crush sub-sample prepared by the laboratory. Crush duplicates show sample reduction and analytical precision (or error). AAL coarse crush (reject) samples comprise – 10 mesh material prepared using jaw and roll crushers.
-
Pulp Duplicate – duplicate pulp prepared by the laboratory after pulverizing the coarse crush material. Pulp duplicates show assay precision or error. AAL pulp samples comprise approximately 200 g of – 150 mesh material pulverized using a ring mill.
Results are reviewed in detail below separately for 2019 – 2021 drilling and for the 2022 drilling – both with a focus on total Ag and Au results.
The database for the duplicate review of 2019 to 2021 drilling comprised: 139 field duplicates; 120 coarse crush duplicates; and 102 pulp duplicates which results in an average insertion rate of approximately 1 duplicate for every 17 assay samples (~16%). Approximately half of all samples had values below the detection limit. The duplicate review comprised basic statistics for all datasets; bias (x-y) plots with RMA correlation lines; and relative difference plots (RDP).
A summary of statistical results for Total Ag and Au results for the Field, Crush and Pulp duplicate sample sets is in Table 11.5 while x-y (bias) plots are shown in Figure 11.7 to Figure 11.12.

*: Recalculated with two outliers removed
For 2019 to 2021 RC drilling, duplicate results show the following behaviour.
-
Average Ag and Au values for field duplicates are significantly higher (approx. 10x) than averages for crush and pulp duplicates.
-
Silver generally behaves well in all duplicates – field, crush and pulp.
-
Coefficient of variation (CV%) for silver is generally about 5-10% higher than desirable for all splits.
-
Possibly due to Ag mineralogy nugget effects especially with lower ICP values?
-
Average Ag and Au values from both field and crush duplicate samples are consistently 8-20% higher than original samples – reason unknown but may be related to sample splitting issue at drill rig and illustrated by poor correlation in field sample - duplicate weights.
-
Coefficient of variation (CV%) for gold is generally about 10% higher than desirable for all splits.
-
CV% gold is approximately the same for field and crush duplicates; crush CV% should be significantly lower
-
The elevated CV% may be due to significant outliers (Samples 204136, 203842, and 203150) which may be mislabelled or mixed samples?

The duplicate database for 2022 RC drilling comprised 64 field duplicates, 50 crush duplicates, and 35 pulp duplicates which reflect insertion rates, based on 2950 total RC assay samples, of approximately 1 per 46 original RC samples, 1 per 59 original RC samples and 1 per 84 original RC samples respectively. In total, duplicate samples are inserted at a rate of 1 per 20 RC samples. Only total Au and Ag values were initially considered in this review - being the metals of principal interest.
The duplicate review comprised basic statistics for all datasets; bias (x-y) plots with RMA correlation lines; and relative difference plots (RDP). X-Y plots for Original Ag value versus Duplicate Ag value and Original Au value versus Duplicate Au value for Field, Crush and Pulp duplicates are shown in Figure 11.13 to Figure 11.18 below. Key metrics for the Field, Crush and Pulp Original and Duplicate samples are summarized in Table 11.6.

Most Original and Duplicate values from 2022 RC drilling correlate well and only two samples appear to be outliers and are circled in Figure 11.14 and Figure 11.16 below. Both outliers are Au values in Field and Crush duplicates. These outliers may reflect mislabelled samples or may just reflect erratic gold distribution in the mineralization. Sample 94969 is mis-identified as a core dup – it is an assay sample. Sample 194180 was submitted as a crush duplicate.

Some observations on the total Ag and Au duplicate results from 2022 RC drilling are:
-
The Mean Percent Difference (MPD) for Au is generally about twice the MPD for Ag and confirms more erratic Au distribution in mineralization.
-
In general, MPD should decrease significantly from Field to Crush to Pulp with decreasing particle size. However, for Ag MPD only decreases modestly from 11.6 to 9.3 and again supports very even distribution of Ag mineralization. MPD for Au decreases significantly from 28.5 to 18.4 again reflecting erratic distribution.
-
As a general rule of thumb, field duplicates should be <30% MPD, coarse duplicates should be <20% MPD and pulp duplicates < 10% MPD. All the duplicates generally meet these criteria except for Au in pulp duplicates (18.4 MPD) again reflecting erratic Au mineralization. Broader limits are generally acceptable for sample results less than 15x the element detection limit which is the case for many of the Candelaria duplicates.
11.3.3.3 Field Blanks
During the 2019 - 2022 Candelaria RC drilling program, field blanks sourced from bags of commercial play sand were inserted into the sample stream at a rate of approximately one blank every 16 RC chip samples. The blank samples serve to monitor for Ag and Au cross contamination due to poor crusher or pulveriser cleaning after processing mineralized samples and to a lesser extent to flag sample switching.
All samples during the current drill campaign were analyzed at American Assay Laboratories (“AAL”) in Sparks, Nevada, USA (ISO accredited Laboratory, ISO/IEC 17025:2017). Samples were analyzed for Ag by ICP-OES while Au was analyzed by FA with ICP finish. Samples over 100 g/t Ag were analyzed by gravimetric methods.
The database of field blanks for Candelaria RC holes completed from 2019 to 2022 comprises 551 blanks reporting both ppm Ag and ppm Au. Time sequential plots for Ag and Au are shown in Figure 11-19 and Figure 11-20 below. The upper limit for Ag is taken as 3 x lab detection or 1.5 ppm Ag and for Au taken as 5 x lab detection or 0.015 ppm Au because of the noisy data. There was only one minor failure for Ag (sample 95715 – 1.7 ppm Ag) and is an improvement on the failure rate for pre-2022 drilling. Four samples failed for Au (172211/95011/196098/196311) none of which coincide with Ag failures.
The Au failures reflect noisy data from low to highly anomalous Au in the material used for the blanks (Figure 11-19 and Figure 11-20). The blank material appears to contain a low background concentration of Au at around the AAL detection limit of 0.003 ppm together with more anomalous scattered values from 0.01 ppm to 0.1 ppm (and one highly anomalous result of 0.66 ppm Au).
The material used for the Candelaria blanks is suitable for monitoring possible Ag contamination but, because of the common results near or above Au detection limit, is not suitable for monitoring possible Au contamination. A better source of reliable coarse blank material should be located for use in future drilling programs.

Subsequent to the 2022 Candelaria RC drilling program, 447 pulp samples (307 from the 2019 to 2021 RC program and 140 from the 2022 RC program) were sent to Paragon Geochemical (Paragon) in Reno, Nevada as a third-party QC check on the primary American Assay Laboratories (AAL) analytical results. Both AAL and Paragon are ISO 17025:2017 certified

Of the 447 pulps submitted to Paragon, 183 samples (41%) returned Below Detection Limit (BDL) for Total Ag (also 183 samples BDL at AAL). Eighteen of the 2020 AAL samples did not include CN soluble results for Ag or for Au. Basic statistics for the original (AAL) and check (Paragon) samples are shown in 811.7. Sample pairs with one or both samples BDL were omitted for the review and discussion below except as noted.
In general, only Total Ag values show good correlation, low scatter and a mean percent difference (MPD) in the range that would be expected for interlab pulp assaying. This result includes one outlier and when the outlier is removed the metrics improve further.

Total Au also displays reasonable correlation between original and check samples although there is a large scatter of results at lower values. Only 39 samples (9%) returned values over 0.1 g/t Au with the highest result being 1.93 g/t Au from both AAL and Paragon. The mean Paragon Au value of 0.06 g/t compares with 0.05 g/t from AAL and is mainly skewed by systematically higher Paragon results on average below 0.1 g/t Au. The MPD value of 40.3 is significantly higher than would be expected even given the erratic nature of gold mineralization – for example, recent AAL intra lab pulp duplicates had an MPD of 18.4 and identical mean values.
Both CN soluble Ag and CN soluble Au show significant differences in mean values between original and check samples when samples BDL are excluded (Table 11.8). The means are strongly influenced by the large number of samples BDL – especially for the Paragon CN Soluble Ag which has a higher detection limit than AAL (0.2 g/t versus 0.01 g/t) and therefore a higher number of excluded samples (209 at Paragon versus 48 for AAL).
The results are also influenced, although to a lesser extent, for CN Soluble Au which also has a higher Paragon detection limit (0.03 g/t versus 0.01 g/t) and more samples excluded (395 at Paragon versus 263 for AAL). When all samples BDL are included, the mean CN Soluble Ag and CN Soluble Au values from Paragon improve and are approximately 10% higher than from AAL.
Some general observations on the Ag and Au Paragon check results are:

-
A comparison of Total Ag between Paragon and AAL showed good correlation and low scatter despite the 0.25 g Paragon sample size versus the 0.5 g AAL sample size. The results confirm the AAL results for Total Ag and the uniform nature of the Ag mineralization.
-
A comparison of Total Au between Paragon and AAL showed reasonable correlation and similar mean values with samples BDL included. The plots and MPD show elevated scatter despite the identical assay methods and significantly higher than AAL intralab duplicate pulps. Part of the issue is likely to be the Paragon Aqua Regia (partial) digestion versus the AAL 4-acid digestion but perhaps also the older pulps required agitation and mixing prior to assaying to ensure more uniform distribution of gold.
-
The checks for CN soluble Ag and Au show reasonable correlation, however, the Paragon samples average approximately 10% higher than AAL results and the scatter of results as measured by MPD is unreasonably high for pulp samples. The Paragon samples used 15 g while AAL used 50 g but this is unlikely to explain all the scatter. Details of AAL CN methodology is not known and should be requested.
11.3.3.5 Sieve Screen Checks
Forty-eight screen checks were completed by Paragon in 2022 to check if the pulps had been prepared by AAL to their stated parameter of 90% passing 150 mesh. Paragon tested 10 g of pulp from approximately 10% of the total pulps submitted.

There are four failures (two serious) in the sieve checks or an 8% failure rate. If the additional three checks at a borderline 90% are included the failure rate would be 15%. The average of all 48 sieve checks was 96% passing 150 mesh.
11.4 QP Comments on Sampling and QA/QC
In general, Silver One has run industry standard or better core and RC sampling and QA/QC programs.
The QP recommends future drill programs consider:
-
Careful control (handling and sampling) of RC field duplicate samples so that weights of original and duplicate samples are better correlated.
-
A reliable source of coarse blank material needs to be located with both Ag and Au values below detection limits. The option of last resort would be to purchase a commercial blank.
-
A subset of samples should continue to be sent to a secondary laboratory for check assays. The analytical procedures used by the secondary laboratory need to be closely aligned with the primary laboratory.
-
The number of different certified standards used should be restricted to 4 to 5 so that more results are returned for each standard and will allow for a more meaningful statistical study and would facilitate recognizing analytical trends and issues. Consideration should be given to developing project-specific matrix-matched standards.

13.0 MINERAL PROCESSING and METALLURGICAL TESTING
Historic silver recoveries by heap-leaching operations between 1980 to 1990 (Occidental Minerals Corporation 1980-1982 and NERCO 1985-1990) averaged 51%. Kinross mined the deposit between 1993 and 1997 and ceased leaching operations in 1999 recovering 42% of the silver (Stevens, 2001), potentially leaving a significant amount of silver in leach pad 2 still available for leaching.
Silver One acquired the Candelaria property in 2017 and shortly thereafter initiated metallurgical testing to evaluate possible processing techniques to recover silver from near-surface mineralization, stockpiles and leach pads material. Recent testing conducted by SVE suggest that Candelaria’s existing mineral resources may be processed by low-cost open-pit, cyanide heap-leach methods, similar to those used in the past. However, better silver recoveries may be achieved by using Highpressure Grinding Roller (‘HPGR’) technology, potentially improving the economics of the project.
Tests completed to date on fresh mineralized material show that addition of HPGR to the crushing circuit increases the historic silver recoveries (42% and 51%) to an average of 67% of the silver, and nearly 50% of the gold (oxide and mixed), which could positively impact the operational results. Cyanide leaching silver recoveries on leach pad material crushed with HPGR to 1.7mm ranges from 29% (LP1) to 40% (LP2).
Silver One is also testing new technologies which have shown the potential to improve the silver recoveries of leach pad material to 63% (LP1) and 69% (LP2). These new technologies are described at the end of this section.
A summary of metallurgical testing completed by Silver One is in Table 13.1.

Other than the known test results summarized above and to the best of the author's knowledge there are no other known processing factors or deleterious elements that could have a significant effect on potential economic extraction.
13.1 Silver Standard 1999 to 2000
By 2001 the Candelaria mineralization had been mined by open-pit methods and processed by heap leaching for over 20 years. During this time extensive metallurgical testing was conducted by its various operators in addition to the heap leach production records.
According to KCA’s investigations commissioned by SSR, reported in a letter dated June 11, 1999, finds that to date for the existing Leach Pad 1, a silver recovery of 51.5 percent, on a fire assay basis; and 86.2 percent, on a cyanide soluble basis was achieved; and considered the leach pad essentially complete in the recovery of leachable silver. KCA also found that to date for the existing Leach Pad 2, a silver recovery of 42.4 percent, on a fire assay basis; and 71.3 percent, on a cyanide soluble basis; and considered the leach pad to still contain a limited amount of leachable silver.
Between late 1999 and early 2000, SSR evaluated possible processing techniques and scenarios for the processing of additional lode and stockpile material, as well as the further processing of the leach pads. (Diaz, R., pers. comm., 2025)
During 2000, SSR commissioned KCA to conduct testing on composites from reverse circulation drill-hole rejects to evaluate various milling scenarios. The testwork included grinding flotation, direct cyanidation and a combination of the two processes. The results indicate that the maximum silver (45% to 88%) and gold (24% to 78%) extraction is achieved by direct cyanidation. A combination of flotation followed by the cyanidation of the flotation tailings did not improve the overall recovery (Beattie, 2000). Given the range of extractions, Beattie’s recommendations included further investigation of materials tested as well as optimization tests for optimum economic returns on the project.
13.2 Silver One 2017 to Present
An extensive and ongoing metallurgical program, testing different silver recovery processes, has been underway since 2017. Work to date has been conducted in three separate laboratories on: a) leach pad and low-grade stockpile (‘LGSP’) samples obtained from the Company’s sonic drilling completed in late 2017- early 2018, b) fresh in-ground samples from the Company’s diamond drilling conducted around Mount Diablo between April and August 2022, and c) bulk samples collected with a backhoe from the bottom of the Mount Diablo pit in August 2023. Metallurgical drill hole and bulk sample locations are shown in Figure 13.1.
13.2.1 Heap Leach Pad and LGSP Testing
13.2.1.1 McClelland 2018
Silver One contracted McClelland Laboratories Inc., of Sparks, Nevada (McClelland) in 2018 to conduct cyanide and ammonium thiosulfate leach testing on composites of leach pad (“LP”) material and of low-grade stockpile (“LGSP”) obtained from the sonic drill holes drilled on the leach pads of the Candelaria Mine.
McClelland tested six composite samples representative of the leach pads (three of each leach pad 1 (“LP1”) and leach pad 2 (“LP2”) with cyanidation leach and ammonium thiosulfate (ATS) leach. In both of these systems, tests were conducted on each composite at feed sizes of 80% -1.7mm. 212µm and 75µm. Composite average silver head grades ranged from 35 to 57 g/t. Average gold grades ranged from 0.07 to 0.24 g/t.

__________
A composite sample of material representing a low-grade stockpile (designated as the LGSP composite) was also subjected to testing. A single cyanidation bottle roll test was conducted on this composite at an 80% -1.7mm feed size, as well as a cyanidation column leach test at an 80% - 37.5mm feed size. Average head grades of the LGSP composite were 24 g/t and 0.15 g/t Au.
At the finest grind size tested (80% -75µm) silver recoveries ranged from 42.9% to 60.4%. Gold recoveries varied widely ranging from <4% to 57.1%.
All composites were sensitive to feed size. Silver and gold recoveries increase with decrease in feed size. On average silver recovery was 22% higher for the 75µm feeds than from the 1.7mm feeds.
The LGSP composite column test silver and gold recoveries were 29.6% and 50% in 80 days of leaching the material at 37.5mm feed size. Silver and gold recoveries by ATS leaching were similar to recoveries by cyanidation leaching.
13.2.1.2 Kappes, Cassiday and Assoc. (KCA) – 2018 to 2023
During late 2018 and 2019, KCA conducted bottle roll leach tests and column leach tests on composite samples from LP1 and LP2. Subsequently, between August 2022 and July 2023, KCA conducted similar set of tests on bulk samples from the bottom of the Mount Diablo pit, as well on core sample material (oxide, mixed and sulphide ores) from diamond drill holes drilled in the Mount Diablo pit area. Sulphide samples were also subjected to flotation testing followed by cyanidation of the tailings.
Bottle roll tests and column HPGR-heap-leach tests were completed on two composite samples representative of each of the leach pads, LP1 and LP2. SVE geologists prepared the samples at the mine-site by extracting a split of all of the holes drilled in LP1 (17 drill holes) and LP2 (10 drill holes). The gold and silver head grades are summarized in Table 13.2.

Results of the bottle roll test work are summarized in Table 13.3. One-kilogram samples were pulverized to 0.15 millimeters (100 mesh) and utilized for bottle roll leach testing. LP1 shows a decreased extraction for gold from 37% to 32% with the higher target sodium cyanide leach solution. Silver extraction increased from 41% to 45% with the increased sodium cyanide leach solution target. LP2 shows an increased extraction for gold with the increased sodium cyanide target leach solution from 20% to 26% while silver extraction increased from 54% to 60%.

Based upon KCA’s experience with mostly clean non-reactive ores, cyanide consumption in production heaps would be only 25 to 33 percent of the laboratory column test consumptions.
Column leach tests were conducted utilizing HPGR product stage crushed material (p80 4 and 1.7 millimeters). During testing, the material was leached for 120 days with a sodium cyanide solution. Column results show that at the 10-mesh feed size (1.7mm), silver and gold recoveries in 120 days of leaching were 40% and 27% respectively for the LP2 composite. Silver and gold recoveries for LP1 composite, at the same feed size, were 29% and 21% respectively. Column results are summarized in Table 13.4.

13.2.2 Mount Diablo Core & Bulk Samples
Six composites from mineralized intervals in diamond drill holes (SO-C-22-132 to 137) completed in September 2022, and three approximately 600kg bulk samples of oxide and mixed material collected at the base of the Mt. Diablo open-pit were sent to KCA in Reno, Nevada for metallurgical testing. All samples targeted the Lower Candelaria Shear (‘LCS’) mineralized zone. The metallurgical drill hole sampling and handling is described in Section 11 while the drill collar information is in Table 10.3 and location is presented in Figure 13.1).
13.2.2.1 Bulk Samples (KCA) – 2022 to 2023
On August 2022, three bulk surface samples consisting of oxide and mixed (oxide-sulphide) mineralized material collected with a backhoe at the base of the Mt. Diablo open-pit (see Fig. 13.1 and Table 13.5) were sent to KCA for bottle roll tests and column HPGR-heap-leach testing.
The bulk samples were homogenized, quartered and two opposite quarters combined for shipping. Individual samples of 325 kg each were sent to KCA for testing while the rest is stored at the Candelaria mine site. One-kilogram split samples were prepared and pulverized to 0.106 millimeters, leached for 48 hours at a target 5 g/L sodium cyanide level for bottle-roll tests. Head grades were determined at the internal KCA laboratory by fire assay and atomic absorption finish (FA/AA 30 grams). Both bulk and core samples were collected, packed and delivered to KCA by Silver One personnel.

| Diablo Pit | N-960 | 326.68 | 405583 | 4222983 |
Bottle Roll Test Work
The initial bottle-roll test extractions for the oxide and mixed bulk samples collected in the Mt. Diablo open-pit ranged from 27% to 60% silver and 62% to 73% gold (Table 13.6). The lower-than-expected silver extractions on the mixed (oxide-sulphide mineralization) are likely to be mineralogy specific to those samples and may not be representative of the entire pit bottom.

Column Leach Test Work
Material from the three bulk samples were crushed at 3/4” (cone) and 1.7 mm (HPGR) respectively for column cyanide leaching. After 120 days of leaching, the extractions reported for material crushed to 1.7 mm with HPGR are 30% to 40% Ag and 48% to 63% Au in mixed material, and 48% Ag and 76% Au in oxide material. The HPGR silver extractions from material crushed to 1.7mm are 8% higher than those obtained from material crushed to ¾” with conventional cone crusher indicating that metal extractions are increased with finer crushing.
13.2.2.2 Core Samples (KCA) 2022 to 2023
On August 2022, six composites from mineralized intervals from six diamond drill holes drilled in the Mount Diablo pit area were sent to KCA for direct leaching (Bottle roll tests) and column HPGR-heap-leach testing. The diamond drill holes are representative of oxide, mixed (oxide and sulphide), and sulphide-rich mineralization within the historic resource area (see Figure 13.1 above for location of drill holes).
Bottle Roll Leach Test Work
Drill hole samples from HQ and NQ core were collected from the entire mineralized intervals of each drill hole using 100% of the core. Samples weighed approximately 100 kg to 180 kg each. 1,000 grams split samples were prepared and pulverized to 0.106 millimeters, leached for 48 hours at a target 5 g/L sodium cyanide level for bottle-roll tests. Head grades were determined at the internal KCA laboratory by fire assay and atomic absorption finish (FA/AA 30 grams). Core samples were collected, packed and delivered to KCA by Silver One personnel.
Bottle roll tests extractions range from 60% to 76% silver, and 68% gold in the oxide diamond drill intercepts; from 70% to 77% silver and 19% to 44% gold in the mixed (oxide-sulphide) diamond drill intercepts; and from 44% to 51% silver and 1% to 3% gold in the sulphide diamond drill intercepts (Table 13.7). The samples were pulverized to a target size of 100% passing 0.106 millimeters and leached for 48 hours.

Note: Drill hole samples from HQ and NQ core were collected from the entire mineralized intervals of each drill hole using 100% of the core. Samples weighed approximately 100 kg to 180 kg each. 1,000 grams split samples were prepared and pulverized to 0.106 millimeters, leached for 48 hours at a target 5 g/L sodium cyanide level for bottle-roll tests. Head grades were determined at the internal KCA laboratory by fire assay and atomic absorption finish (FA/AA 30 grams). Core samples were collected, packed and delivered to KCA by Silver One personnel.
Column Leach Test Work
Material from the six drill-holes samples were crushed at 1” (cone) and 1.7 mm (HPGR) respectively for column cyanide leaching. The material conventionally crushed was leached for 183 days while material crushed with HPGR was leached for 158 days (Figure 13.2).
Average silver extractions for samples crushed with HPGR are 58%, 61% and 72% for sulphide, oxide, and mixed material, respectively. In comparison to historic recoveries of 51%, the above extractions represent an increase of +14%, +20% and +41% for sulphide, oxide and mixed materials, respectively. Average silver extractions of samples crushed with conventional cone crushing are 47%, 53% and 62% for sulphide, oxide, and mixed material respectively). Leaching of gold works well on oxides but not in mixed material and sulphide. Gold extractions of oxide material crushed

with HPGR average 70%, compared with 73% obtained with conventionally crushed material. Gold extractions from sulphides and mixed material crushed with HPGR, average 4% and 28%, respectively, while extractions from conventionally crushed samples averaged 3% and 34% respectively. According to KCA, the estimated field extractions are typically three to five percentage points below the lab extractions.

Flotation-Cyanidation on Sulphide Samples
Flotation extractions were conducted by KCA on two sulphide samples obtained from drill core of holes SO-C-22-132 and SO-C-22-133. Flotation extractions average 62% silver, 72% gold, 50% lead and 37% zinc. The sulphide results are improved by leaching the flotation tails. Flotation followed by cyanidation of the tails increases the extractions to a range between 71% to 84% silver (average 77.5%) and 75% to 89% gold (average 82%).

13.2.3 Other Technologies - Extrakt/Bechtel
During 2023, Extrakt Process Solutions (“EPS”) of Bowling Green, KY conducted agitated noncyanide leach tests on leach pad samples and during 2024, agitated and column non-cyanide leach tests on both leach pad samples, and core samples from diamond drill holes drilled in the Mount Diablo area. The core samples are representative of the in-ground LCS mineralization in the project.
Extrakt metallurgical results are compared to KCA and McClelland results in Table 13.8.
13.2.3.1 Candelaria Leach Pad Samples
Bulk samples representative of leach pad 1 (LP1) and leach pad 2 (LP2) weighing 228 kg and 263 kg respectively, composited from sonic drill holes drilled and analyzed by Silver One in 2017 and 2018, were entirely crushed to ≤2 mm (<2000 microns) with a Vertical Shaft Impact crusher at CEMCO’s facilities in Belen, NM, and shipped to the EPS laboratory in Kentucky for metallurgical testing. The material consisted of leached oxide and partially refractory material with silver head grade of 51.3 g/t and 50.1 g/t for LP1 and LP2 respectively.
Representative portions of the bulk samples were weighed and sieved to separate two fractions. Material smaller than 2 mm was used for testing. The tests were conducted on 1 to 2 kg splits of the sieved (<2 mm) material. Splits tested were prepared according to acceptable industry standard practices (homogenized, coned and quartered several times). The minus 2 mm size was selected because of economic reasons, as it is a size fraction that can be achieved with one single stage of HPGR crushing. This is less expensive than milling to a much finer size and yields better silver recoveries than those obtained by historical leaching of the coarser (1 inch = 25.4 mm) material existing in Candelaria’s leach pads (see the Company’s news release of April 19, 2018 and National Instrument 43-101 (“NI 43-101”) technical report filed on SEDAR+ by the Company in 2020 titled “Technical Report on the Heap Leach Pads within the Candelaria Property”).
The current optimized agitated-leach silver recoveries using EPS’ proprietary solutions average 59.1% for LP1, and 51.1% for LP2 on samples as received at the lab (<2 mm = 2000 microns), which significantly exceed the 20.9% and 27.9% silver recoveries achieved with cyanide leaching from bottle roll tests using material of similar size of LP1 and LP2 respectively (See Table 13.8) and the Company’s news release dated May 21, 2019). Phase 1 leaching results of samples tested at different particle sizes, show that the silver recoveries increase with decreasing particle size which warrants additional testing to optimize silver recoveries at finer grind sizes and tradeoff analysis to evaluate the economic benefits of finer grinding. EPS’ leach times during phase 2 testing were between 6 and 7 hours further reducing the leach times of 48 hours or more used for cyanide leaching.
EPS’ column leach tests were done on minus 2 mm material for both LP1 and LP2. The reported silver recoveries were 63% and 69% for LP1 and LP2 respectively, which bode well for the prospects of heap-leaching. These results above highlight the potential to use EPS’ technology in heap-leach scenarios (at crush sizes of 2 mm), which may positively impact the economics of the project.
13.2.3.2 Candelaria Core Samples
Three drill-core samples from holes 132, 135 and 136 crushed to 1.7 mm with HPGR by KCA, weighing 9.52 kg, 9.6 kg, and 37.1 kg respectively, were shipped to EPS laboratory in Kentucky for metallurgical testing. The samples consisted of oxide (drill hole 135), sulfide (drill hole 132) and mixed (drill hole 136) mineralization with silver head-grades of 147 g/t, 419 g/t, and 115 g/t, respectively.

The samples were prepared in a similar manner as the LP samples above. A split of the <2 mm fraction was tested as is, and 1 to 2 kg splits were further ground to 500 µm and 250 µm for agitated leach testing. Column testing was performed on the sulfide sample only due to insufficient oxide and mixed material .
The optimized silver recoveries of agitated leaching tests using EPS’ proprietary solutions are 68.2%, 59.4% and 80.4% for the oxide, sulfide and mixed material as received at the lab (<2 mm = 2000 microns) respectively.

the same oxide, sulfide and mixed material crushed with HPGR to 1.7 mm (See Table 13.8 and the Company’s news release dated June 14, 2023) suggest that cyanide leaching of fresh material may reach similar range of recoveries so far achieved by EPS’ proprietary solutions.

14.0 MINERAL RESOURCE ESTIMATES
14.1 Introduction
The Candelaria deposit was originally mined by selective underground methods starting around the late 1800s and early 1900s, and by open-pit methods from 1980 to 1997. The dipping mineralized zones for both the Mount Diablo and Northern Belle deposits continue at depth beyond the margins of the current pit limits. Figure 14.1 shows the relative location of the various resource areas.
This mineral resource estimate has been prepared following the CIM guidelines and is restricted to only the Mount Diablo open pit, the Mount Diablo underground, and the Northern Belle open pit, all areas within the Candelaria property. The leach pads and low-grade stockpiles were reported in a previous NI 43-101 report (McCrea, 2020) by the author and is referenced in the appropriate section. It does not explicitly or implicitly refer to resources contained in any of the other mineralized zones within the Property. Mr. James A. McCrea, P. Geo., carried out the modelling and estimate of the mineral resources, a qualified person with respect to mineral resource estimation under NI 43-101. Mr. McCrea is independent of Silver One by the definitions and criteria set forth in NI 43-101, and there is no affiliation between the author and the company except that of an independent consultant-client relationship.
Since early historical development, silver grades used in the resource and reserve estimates and production records at Candelaria have been based on soluble (leachable) silver grades (AgCN) and gold grades (AuCN) obtained from hot cyanide leach methods, since the previous open-pit operation’s focus for processing was on heap leaching the silver.
These subject mineral resources have no known issues and do not appear materially affected by ‐ any known environmental, permitting, and legal, title, taxation, socio economic, political, or other relevant issues. The effective date of this mineral resource estimate is April 30, 2025.
14.2 Factored Silver and Gold
In early 2025, Silver One updated the regression formulas used for calculating Total Ag and Total Au (Factored Ag and Factored Au) in historic holes reporting only CN soluble Ag and Au values. The regression formulas used are:
-
Mt. Diablo Oxide/Mixed: Ag T = (AgCN * 1.9244) + 2.07
-
Mt. Diablo Sulphide: Ag T = (AgCN * 2.0718) +1.995
-
Northern Belle Oxide/Mixed: Factored Ag T = (AgCN * 1.4002) + 1.7975
-
Mt. Diablo: Factored Au T = 1.2534 * AuCN
-
Northern Belle: Factored Au T = 1.2438 * AuCN + 0.01125
The 2025 Factored Ag and Au regression formulas are based on SSR re-assays of pulps from Nerco Mount Diablo and Northern Belle drill holes (230 samples with both FA Ag and mine AgCN), SSR AgCN results levelled to approximate equivalent mine results (305 samples from Mount Diablo only), several Nerco drill results reporting FA Ag Total (63 samples from four Mt. Diablo drill holes), and eight C-holes with FA Ag at Northern Belle to increase the available samples used for regression calculations. (Cann and Watkins, 2025).

14.3 Metal Equivalents
The silver equivalents used in this report use the total silver (Ag T) and total gold (Au T) with recoveries determined from metallurgical testing (Table 14.1) to calculate AgEq T based on a USD$2106.00 per ounce gold price and USD $27.50 per ounce silver price. Additionally, a silver equivalent was calculated using soluble silver (AgCN) and soluble gold (AuCN) grades using metallurgical recoveries for silver equivalent (AgEq).
The factored silver and gold grades were used for the AgEq T equivalent because the metallurgical recoveries are based on fresh material and the factoring was used to estimate fire assay grades from the cyanide soluble portion of the database. The AgEq grades are based on the same recoveries as used for AgEq T and are shown in Table 14.1.

14.4 NSR Calculations
Silver One contracted International Mining Consultants (“IMC”) of Tucson, Arizona to conduct pit optimizations, open-pit and underground mine planning as well as to estimate mining capital and operating costs. IMC used KCA’s metallurgical recoveries and costs for pit designs and resource reporting as well as Net Smelter Return (NSR) to combine the values of all economic metals. Simply put, NSR, expressed in $/tonne, is the total sales value net of all off-site costs for smelting and refining. Using the metal prices and costs summarized in Table 14.28, the equations for NSR are as follows based on the metal grade units provided in the model.
Silver NSR = Ag grade x Recovery x (1-Royalty) x (Price – Ag Refine) x 0.03215 + Gold NSR = Au grade x Recovery x (1-Royalty) x (Price – Au Refine) x 0.03215 Total NSR = Silver NSR + Gold NSR
Silver recoveries used for the NSR varied from 55 to 66%, and gold recoveries from 0 to 51% depending on the mineralization type of each block. The average grades of earlier mine plans indicated that silver makes up approximately 84% of the value, and gold makes up the remaining value of around 16%. The internal cutoff for NSR is $9.273/tonne, the total of the processing and G&A unit costs.
The base case NSR was calculated for every block in the model. Then, to establish pit design guidance for smaller pits, the NSR was reduced by factoring downward on a percentage basis (revenue factors). Rather than reporting revenue factors for each cone, the resulting gold price from each factor is reported on the summary tables since silver is the most valuable metal for Candelaria.

Page 122
The pit optimizations were calculated at $0.50/oz incremental silver prices (gold prices were scaled at the same ratio of price increments) between $20/oz and $32/oz. Each of the incremental optimized pits were tabulated at a metal price ($27.50/oz silver price) to establish the incremental tonnage, grades and potential income (net of processing and G&A costs) within each of the optimized pits.
The resulting graphics are presented in terms of metal prices, but the reader should keep in mind that the value of all metals is included in the development of the computer-generated pit geometries.
14.5 Drilling and Assay Database
The drill hole data for Mount Diablo was provided by Silver One in the form of Microsoft Excel spreadsheets containing location, survey, and analytical data for 680 historic and recent drill holes. Data included 98 diamond and RC drill holes from three recent drill programs from 2019 to 2022, with holes collared around the Mount Diablo and the Northern Belle open pits. The database contains some 54,124 samples analyzed for soluble gold and silver. Recent drilling data (since 1999) contained samples also analyzed for total silver by ICP or gravimetric methods and gold by fire assay and a multi-element ICP. The drilling and assay data provided by Silver One appears to be adequate for the purposes of this mineral resource estimate and the author has no reason to believe that any of the information is inaccurate.
The Northern Belle drill data was imported and validated at the same time as Mount Diablo. The database received from SSR mining contained data for 234 drill holes that were analyzed for cyanide soluble silver and gold that were drilled by previous operators on Northern Belle. Silver One drilled 17 drill holes that were analyzed by fire assay for gold and an ICP with silver over limits by gravimetric methods plus cyanide soluble assays for gold and silver, and a multi-element ICP for a total of 251 holes. The database contains 22,672 assays for Northern Belle where 21,338 assays where only cyanide soluble and 1334 assay fire assays and a multi element ICP.
When there were several analytical procedures performed on individual samples, often as a result of the measured silver and/or gold grades exceeding the limits of precision for a particular analytical technique, the assay result from the most accurate procedure was considered the ‘final’ value (i.e., Fire Assay/Gravimetric superseded Fire Assay/Atomic Absorption which superseded ICP values). All ‘below detection limit’ analytical values were assigned one-half the lower detection limit value for the purposes of this resource estimate. All data are expressed in SI units and grid coordinates are in the UTM NAD83 Zone 11 North Datum.
14.6 Sample Compositing
Mount Diablo 3-metre bench composites were calculated from soluble gold and silver values and the total gold and total silver values based on the benches from the model that ranged from 1,471 to 1,960 metres in elevation at the toe. The composites, including the SSR drilling, and the composites from the Silver One drill programs were added for 17,538 soluble silver and gold composites in the database. The database also contained assay values for total silver (Ag T), and total gold (Au T). These composites from Mount Diablo were used to interpolate the resource model.
At Northern Belle, equal length 3 metre down hole composites were calculated from capped assay soluble gold, total gold, and total silver values. These 3 metre composites were generated starting from the collar of the drill hole to the toe. Sample compositing produced 14,872 3-metre composites in total which were used to interpolate the resource model.

Any intervals not assayed were assigned a ‘Not Sampled’ (‘NS’) designation which excluded it from any composite calculation, and any composites less than half the composite length were discarded so as to not introduce a short sample bias in the interpolation process. Composite statistics as listed in the Table 14.2 for Mount Diablo and in Table 14.3 for Northern Belle. In the tables below, Domains 1 and 10 correspond the LCS which is the principal mineralized unit. Domains 2 and 20 are mineralized material above the LCS while Domains 3 and 30 are all other mined material.
The QP has reviewed the composite statistics and believes the data set is sufficient for resource estimation at Candelaria.

14.7 Three-Dimensional Solid Modelling
Geologic solid models were constructed by Silver One using 30 m-spaced, north-south sections. Three grade/structural domains and three geologic domains were defined based on geology and structure, including the Lower Candelaria shear (LCS – Domains 10 and 1), secondary structures in the hanging wall (Domains 20 and 2), two geologic domains, waste dumps, and a background domain (Domains 30 and 3). For the interpolation of the LCS, Domain 10 was divided into 13 sub domains separated along east west fault lines to restrict the interpolation to data coded for that faulted block. The grade and geologic domain solids were used to code the rock type model, percent model, and the LCS domain model, which controls the grade assignment during the interpolation process. Solid models are shown in Figure 14.2.

14.8 Specific Gravity Estimation
Historically, the bulk density used for the mine during the entire duration of the open-pit mining operation was 13.5-cubic-feet-per-ton for oxide material (Stevens, 2001), which converts to 2.37 tonnes/m[3] . Silver One undertook a program of sampling for specific gravity (“SG”) determinations in 2022 and 78 core samples were submitted for SG determination. This specific gravity model is based on the oxide state of the sampled tested. The SG samples were plotted on sections then oxide, mixed and sulphide domains created to code the density model. The final in-situ densities used are listed in Table 14.4.

The bulk density used for the leach pad mineral resource estimate was the same as historically used at the mine during the entire duration of the open-pit mining operation. The tonnage conversion factor was 13.5-cubic-feet-per-ton for oxide material (Stevens, 2001) or 2.37 t/m[3] plus a swell factor for the density of leach pad material.
The densities used for LP1 and LP2 were validated with the solid models against reported mine production. The final in-situ densities used are 1.88 for LP1 and 1.76 for LP2.
14.9 Grade Capping
The methodology used was to cap the assays before compositing. Grade capping the composites controls high-grade outliers in the composite data so as to limit their effect on the grade model. Cumulative probability plots of Domain assays were used to identify high-grade outliers for soluble silver, soluble gold, total silver, and total gold composites contained within the Domain solid models. The top-cuts for Mount Diablo are listed in Table 14.5 and for Northern Belle in Table 14.6.

14.10 Block Model Description
An un-rotated, three-dimensional block model was created in GEMS to completely cover the Mount Diablo (MD) and Northern Belle (NB) zones. The Block Model parameters are presented in Table 14.7.

| Axis Direction |

Axis | Axis Nomenclature |

| Northing | 000o | Y | Row | 4222525 | 7.5 | 226 |
| Elevation | Vertical | Z | Level | 1963 | 3.0 | 164 |
Separate block models were created for rock type, density, soluble silver, soluble gold, total silver, total gold, and classification. In addition, several special models were created including Distance (to the Closest Sample), Number of Samples (used in block classification), and models for verification.
Two models were created for Candelaria, a percent or ‘partial model’ and a ‘whole block model’. The partial model is created in multiple folders each with a percent model and this allows for a more accurate estimation of volume and tonnes in the model. Folders are used for each grade domain plus a Standard folder for background and waste rock types.
The 'whole block' model used for Candelaria was created to accurately represent the volume and subsequent tonnage that was occupied by each block inside the constraining domain solid. The block model was coded for air (i.e., above topography), background (i.e., outside the solid models) and the domain by coding blocks with a greater than fifty percent (50%) threshold. Blocks with more than 50% of the block inside the solid were given the code of that domain solid.

14.11 Mount Diablo Resource Estimation
14.11.1 Semi-Variogram Analysis
The variography was completed using Isaaks & Company Sage (2001) software with the 3-metre bench composites. The variograms were completed by domain and run for soluble silver and gold, and total silver and gold.
Conventional correlogram variography was used to model the grade continuity. Nugget effects were estimated from down-hole semi-variograms. The major, semi-major and minor axes for grade continuity were determined using oriented semi-variogram fans. The variograms were used to model search ellipses that were then defined for resource estimation utilizing the GEMS Z-Y-Z rotation convention.
Search ellipses were produced for each grade-element after multiple experimental semivariograms had been generated at 30-degree intervals for strike and 15-degree intervals for dip. Modelling of both the silver and gold continuity produced moderate to good quality experimental semi-variograms. The results of the semi-variogram analyses are shown in Table 14.8.
14.11.2 Interpolation
Ordinary kriging was used to interpolate the soluble silver (AgCN), soluble gold (AuCN), and total silver (Ag T) grades in the block model for rock types 10 and 20 using the searches listed in Table 14.8. Rock type 30 used ordinary kriging for soluble silver and total silver while inverse distance cubed was used for soluble gold. The domain boundaries were honored by the kriging process whereby samples from within a domain were used to interpolate only the blocks within that domain.
Initial visual inspections of sample grades versus the block grades for rock type 30 found, possibly because of wider spaced data, that the interpolation was over estimating grade for soluble gold. To make the lower grade areas of rock type 30 more conservative, a high-grade search restriction, to one block, was used with long searches restricted to 80% of the correlogram range. The search distances used for interpolating rock type 30 are also listed in Table 14.8.
14.11.3 Interpolation Validation
The validation of the Mount Diablo block model included visual inspections of the block grades versus composite values and geologic model, block model swash plots for soluble silver, and a ‘one out’ cross-validation.
The ‘one out’ cross-validation routine is used for validating kriged models. It is a discretionary sub-routine within the GEMS interpolation profile that involves the removal of a single point from the data set and the estimation of a temporary block at that point using the remaining data. Values are then estimated for all the data points in the data set. The original values and the estimated values for all the data points in the data set can then be statistically analysed and graphed. The scatter plots, without zeros, are used to examine the relationship of the original values to the estimated values by plotting the original values vs. estimated values, the difference vs. the estimated values. To check if the interpolation is under or overestimating, the percent difference of the means of the original and estimated values is calculated.
The results of the ‘one out’ cross-validation are used to calculate the difference between the mean of the estimated input grades the from interpolation and the mean of the actual input grades from

the composite dataset as a percentage of the mean of the actual composite grades. The difference between the mean of estimated input grades and the actual mean of the composite grades for the rock type 10 interpolation pass for soluble silver was -6.51%. The negative value indicates the interpolation is slightly overestimating the block grades versus the sample grades for that domain. Table 14.9 contains a summary of the ‘one out’ cross validation results by domain.
The ‘one out’ cross-validation was used to ‘fine tune’ the number of samples used for interpolation. The cross-validation graphs were produced for a range of interpolation profiles for silver with a different maximum number of samples used in the interpolation. The graphs were used to check on the effects of more data or averaging during the interpolation run. The final interpolation profiles were revised to have the highest number of samples that produced the best crossvalidation results.

Graphs of the trends of mineralization through the deposit were produced for soluble silver. The graphs slice the deposit into 30-metre slices and plot the average block grades, number of samples, average sample grades and tonnage for the slices. The graphs plot the trends of the mineralization and graphically represent the deposit so that the trends can be checked for irregularities or anomalies. The graphs for silver are shown below in Figures 14.3 to 14.5. The validation graphs do not show any irregularities.

14.11.4 Mineral Resource Classification
Mount Diablo resources were classified based on the block distance to the closest composite value and the number of composite values used in the estimation of the block. The distance model was written with the soluble silver interpolation and ranges are shown in Table 14.10.
The has author has reviewed the criteria and believes that it is reasonable and that it meets the definitions of measured, indicated, and inferred mineral resources as stated by National Instrument 43-101 and as defined by the CIM guidelines for the reporting Mineral Resources and Mineral Reserves.

1. A Mineral Resource is a concentration or occurrence of solid material of economic interest in or on the Earth’s crust in such form, grade or quality and quantity that there are reasonable prospects for eventual economic extraction.
An Inferred Mineral Resource is that part of a Mineral Resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity.

An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
An Indicated Mineral Resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit.
Geological evidence is derived from adequately detailed and reliable exploration, sampling and testing and is sufficient to assume geological and grade or quality continuity between points of observation.
An Indicated Mineral Resource has a lower level of confidence than that applying to a Measured Mineral Resource and may only be converted to a Probable Mineral Reserve.
A Measured Mineral Resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape, and physical characteristics are estimated with confidence sufficient to allow the application of Modifying Factors to support detailed mine planning and final evaluation of the economic viability of the deposit.
Geological evidence is derived from detailed and reliable exploration, sampling and testing and is sufficient to confirm geological and grade or quality continuity between points of observation.
A Measured Mineral Resource has a higher level of confidence than that applying to either an Indicated Mineral Resource or an Inferred Mineral Resource. It may be converted to a Proven Mineral Reserve or to a Probable Mineral Reserve.
2. Mineral resources, which are not mineral reserves, do not have demonstrated economic viability. The estimate of mineral resources have no known issues and do not appear materially affected by any known environmental, permitting, legal, title, socio-political, marketing, or other relevant issues. There is no guarantee that Silver One will be successful in obtaining any or all of the requisite consents, permits or approvals, regulatory or otherwise for the project or that the project will be placed into production.
- The mineral resources in this study were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (‘CIM’), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the Standing Committee on Reserve Definitions and adopted by the CIM Council on May 10, 2014. 4. Silver Equivalent calculated using AgEQ formula = Ag + (Au * met recovery *67.73/0.8841) (US$2106.00 per ounce gold price and USD $27.50 per ounce silver price), Met recoveries in Table 14.1.

14.12.2 Block Model
The Northern Belle (NB) block model is as described in Section 14.10 with the block model parameters shown in Table 14.7.

Ordinary kriging was used to interpolate the soluble silver (AgCN), soluble gold (AuCN), total silver (Ag T), and total gold (Au T) grades in the block model for rock types 1 and 2 using the searches listed in Table 14.13. Rock type 3 used ordinary kriging for soluble silver and total silver while inverse distance cubed was used for soluble gold and total gold. The domain boundaries were honored by the kriging process whereby samples from within a domain were used to interpolate only the blocks within that domain.

14.12.1 Interpolation Validation
The validation of the Northern Belle block model included visual inspections of the block grades versus composite values, block model swash plots for soluble silver, and a ‘one out’ crossvalidation.
The ‘one out’ cross-validation routine is used for validating kriged models. It is a discretionary sub-routine within the GEMS interpolation profile that involves the removal of a single point from the data set and the estimation of a temporary block at that point using the remaining data. Values are then estimated for all the data points in the data set. The original values and the estimated values for all the data points in the data set can then be statistically analysed and graphed. The scatter plots, without zeros, are used to examine the relationship of the original values to the estimated values by plotting the original values vs. estimated values, the difference vs. the estimated values. To check if the interpolation is under or overestimating, the percent difference of the means of the original and estimated values is calculated.
The results of the ‘one out’ cross-validation are used to calculate the difference between the mean of the estimated input grades the from interpolation and the mean of the actual input grades from the composite dataset as a percentage of the mean of the actual composite grades. The difference between the mean of estimated input grades and the actual mean of the composite grades for the rock type 1 interpolation pass for soluble silver was -0.82%. The negative value indicates the interpolation is slightly overestimating the block grades versus the sample grades for that domain. Table 14.14 contains a summary of the ‘one out’ cross validation results by domain.
The ‘one out’ cross-validation was used to ‘fine tune’ the number of samples used for interpolation. The cross-validation graphs were produced for a range of interpolation profiles for silver with a different maximum number of samples used in the interpolation. The graphs were used to check on the effects of more data or averaging during the interpolation run. The final interpolation profiles were revised to have the highest number of samples that produced the best crossvalidation results.

| Domain | Unit | Estimated Grade Mean |
Actual Grade Mean |
Difference (%) |
|---|---|---|---|---|
| 1 | g/t | 66.65 | 62.31 | -0.82% |
| 2 | g/t | 8.80 | 8.90 | -0.27% |
| 3 | g/t | 2.30 | 2.36 | -0.38% |
Graphs of the trends of mineralization through the deposit were produced for soluble silver. The graphs slice the deposit into 30-metre slices and plot the average block grades, number of samples, average sample grades and tonnage for the slices. The graphs plot the trends of the mineralization and graphically represent the deposit so that the trends can be checked for irregularities or anomalies. The graphs for silver are shown below in Figures 14.7 to 14.9. The validation graphs do not show any irregularities.

14.12.2 Mineral Resource Classification
Northern Belle resources were classified based on the block distance to the closest composite value and the number of composite values used in the estimation of the block. The distance model was written with the soluble silver interpolation and ranges are shown in Table 14.15.
The has author has reviewed the criteria and believes that it is reasonable and that it meets the definitions of measured, indicated, and inferred mineral resources as stated by National Instrument 43-101 and as defined by the CIM guidelines for the reporting Mineral Resources and Mineral Reserves.

1. A Mineral Resource is a concentration or occurrence of solid material of economic interest in or on the Earth’s crust in such form, grade or quality and quantity that there are reasonable prospects for eventual economic extraction.
An Inferred Mineral Resource is that part of a Mineral Resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity.
An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
An Indicated Mineral Resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit.
Geological evidence is derived from adequately detailed and reliable exploration, sampling and testing and is sufficient to assume geological and grade or quality continuity between points of observation.
An Indicated Mineral Resource has a lower level of confidence than that applying to a Measured Mineral Resource and may only be converted to a Probable Mineral Reserve.

14.13 Leach Pad Resource
Leach pad mineral resources were previously reported in 2020 and will only be summarized here. The reader is referred to the technical report by McCrea (2020) where complete details of the resource estimation are documented.
14.13.1 Drilling and Assay Database
The 2017 sonic drill data was provided by Silver One in the form of Microsoft Excel spreadsheets. The Excel spreadsheet files contained location, survey, analytical data for the forty-five 2017 sonic drill holes collared on the leach pads and low-grade stockpiles. The author provided the data for the 36 sonic drill holes drilled on LP1 in 1992 by NERCO. The drilling and assay data provided by Silver One appears to be adequate for the purposes of this mineral resource estimate and the author has no reason to believe that any of the information is inaccurate.
14.13.2 Three-Dimensional Solid Modelling
Solid models of the leach pads were created from topographic contours of their bases, originally used for leach pad construction, and surface contours of the leach pads. Triangulated interconnected networks (TIN's) were created from the top and bottom contours of the leach pads
14.13.3 Sample Compositing
Equal length three metre (3.0 m) assay sample composites were calculated from capped assayed gold and silver values for the sonic drill holes. These 3.0 metre composites were generated starting from the collar of the sonic drill hole to its terminus where the drill holes are within the solid models of the leach pads. Any un-assayed intervals were assigned a ‘Not Entered’ (‘NE’) designation which excluded it from any composite calculation, and any composites less than 1.5 m in length were discarded so as to not introduce a short sample bias in the interpolation process.
Sample compositing the 838 assays in the solid models produced a total of 471 3-metre composites in total where 382 composites were from LP1 and 89 were from LP2. These composites were used to interpolate the resource model, where composite and assay statistics as listed in the Table 14.17.

14.13.4 Grade Capping
Cumulative probability plots were used to identify high-grade outliers for both silver and gold assays contained within the solid models of leach pads. Based upon the graphical results, raw silver assays were capped at 109.3 g/t representing the 99.30% of the 838 raw silver assays. Six silver values exceeding the cap level were each reduced to 109.3 g/t. The raw gold assay probability plot indicated a capping level at 0.343 g/t representing 99.40% of the total 838 gold assay values. Five gold assays exceeding the cap level were each reduced to 0.343 g/t.
14.13.5 Block Model
An un-rotated block model was created in GEMS software to completely cover the sonic drilltested areas: LP1 and LP2. The Block Model parameters are presented in Table 14.18.

| Northing | 000o | Y | Row | 4222150 | 5 | 770 |
| Elevation | Vertical | Z | Level | 1925 | 2.5 | 130 |
Separate block models were created for Rock Type, Density, Percent, Class, Gold and Silver. In addition, several special models were created including Distance (to the Closest Sample for first pass interpolation), Number of Samples (used in block estimation), and models for verification.
14.13.6 Semi-Variogram Analysis
The Sage 2001 variography software was utilized to evaluate the spatial continuity of the silver and gold mineralization using the capped 3-metre composite data within the constrained solid models. Conventional correlogram variography was used to model the grade continuity. Nugget effects were estimated from down-hole semi-variograms.
Search ellipses were produced for each grade-element (gold and silver) after multiple experimental semi-variograms had been generated at 30-degree intervals for strike and 15degree intervals for dip. Modelling of both the silver and gold continuity produced moderate to poor quality experimental semi-variograms. The semi-variogram models produced for LP2 and the LGSP's were lacking data density, which is due to the small data set for that part of the resource. The LP1 variograms produced a flat-lying ellipse, slightly elongated on the Y axis. The LP1 search ellipse was used for all zones. Searches are detailed in Table 14.19.

14.13.7 Interpolation
Based upon the modelled search ellipses, silver and gold grades were estimated for each block in the block model using capped grade composites with an ‘Inverse Distance Squared’ interpolation.
Grade interpolation was carried out in two interpolative passes. The interpolation estimated grade in the solid models for silver and gold, requiring a minimum of 2 samples and a maximum of 12 samples to estimate a block for the first pass and a minimum of 1 sample and a maximum of 12 samples to estimate a block for the second pass. The second pass used an expanded search ellipse to write only ‘zero’ blocks within the search range.

14.13.8 Interpolation Validation
The validation of the leach pad and low-grade stockpile block model included visual inspections of the block grades versus silver and gold composite values and comparison of solid volumes to reported block model volumes.
A preliminary Inverse Distance Squared interpolation run was conducted to provide a visual check on the interpolation parameters. Visual inspections of the silver and gold block models on section and plan showed that the interpolation had extrapolated grades with reasonable values and distribution throughout the modelled domain.
Volume of the leach pad solids was checked against the block model and historic production records. The calculated LP1 volume of 11,886,170.0 m3 was checked against the 0.01 g/t Ag cutoff volume reported in the resource estimate of 11,799,162.0 m3. The block model is reporting 99.27% of the domain solid volume.
14.13.9 Mineral Resource Classification
Mineral resources in the LP1 have been classified as 'Indicated mineral resources' and LP2 has been classified as 'Inferred mineral resources'. These classifications are based on drill density.
14.13.10 Metal Prices
Metal prices used for the leach pad resource estimate are US $1500 per ounce for gold and US $20 per ounce of silver. These prices are used for calculating silver equivalents and for the exploitation scenarios related to reasonable prospects for eventual economic extraction.
14.13.11 Leach Pads Mineral Resource Statement
The leach pads will be mined in their entirety with no grade control or selectivity.

14.14 Low Grade Stockpile Resource
14.14.1 General
Sub-ore grade material from open-pit mining of the Lucky Hill and Mount Diablo pits was placed in two stockpiles from the start of production in 1980 until the mid- to late-1980s. This low-grade mineralized material remains in two stockpiles, the larger of which is referred to as the SP-W stockpile, located near the southwest corner of the Mt. Diablo pit. The smaller SP-E stockpile is located 500 m northeast of the east wall of the Mount Diablo pit.
14.14.2 Drilling and Assay Database
In 2017, five sonic holes tested the SP-E stockpile and nine holes tested the SP-W stockpile. All holes were drilled from top of the stockpile into bedrock. The 2017 sonic drill data was provided by Silver One in the form of Microsoft Excel spreadsheets. The spreadsheet files contained location, survey, analytical data for the fourteen sonic drill holes collared on the two low-grade stockpiles. The drilling and assay data provided by Silver One appears to be adequate for the purposes of this mineral resource estimate and the author has no reason to believe that any of the information is inaccurate.
14.14.3 Specific Gravity Estimation
A specific gravity of 1.90 t/m[3] was used to calculate LGSP tonnage which is similar to the historical SG of 1.96 t/m[3 ] used at the mine for dumps and waste.
14.14.4 Three-Dimensional Solid Modelling
The low-grade stockpiles surface triangulated interconnected networks (“TINs”) were created from Lidar-derived surface contours but the bases were created using a 5 g/t Ag cut-off. Points from the top of assays below cut-off were used to create the bottom surface by Laplace gridding. The low-grade stockpile extents were modelled as approximately a 30 m projection around the drill collars.
These 3D solid models were used to code the rock type model for the block model, code the domain of the assays and composites.
14.14.5 Sample Compositing
Equal length three metre (3.0 m) assay sample composites were calculated from gold and silver values (168 assays) for the sonic drill holes. These 3.0 metre composites were generated starting from the collar of the sonic drill hole to its terminus where the drill holes are within the solid models of the leach pads. Any un-assayed intervals were assigned a ‘Not Entered’ (‘NE’) designation which excluded it from any composite calculation, and any composites less than 1.5 m in length were discarded to not introduce a short sample bias in the interpolation process.
14.14.6 Grade Capping
There were no drill samples exceeding 98 g/t Ag and 0.3 g/t Au (Fire Assays) so no grade capping was required.
14.14.7 Block Model
An un-rotated block model was created in GEMS software to completely cover the sonic drilltested SP-E and SP-W. The Block Model parameters are presented in Table 14.18.
Separate block models were created for Rock Type, Density, Percent, Class, Gold and Silver. In addition, several special models were created including Distance (to the Closest Sample for first pass interpolation), Number of Samples (used in block estimation), and models for verification.

Based upon the modelled search ellipses, silver and gold grades were estimated for each block in the block model using grade composites with an ‘Inverse Distance Squared’ interpolation. Grade interpolation was carried out in two interpolative passes. The interpolation estimated grade in the solid models for silver and gold, requiring a minimum of 2 samples and a maximum of 12 samples to estimate a block for the first pass and a minimum of 1 sample and a maximum of 12 samples to estimate a block for the second pass. The second pass used an expanded search ellipse to write only ‘zero’ blocks within the search range. During interpolation the number of samples used for each grade element interpolation and the closest true distance to an actual composite sample were written to the ‘Number of Samples’ and ‘Distance’ block models respectively.

Mineral resources in the Low-Grade Stockpiles have been classified as Inferred mineral resources based on drill density.

An Inferred Mineral Resource is that part of a Mineral Resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity.
An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
An Indicated Mineral Resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit.
Geological evidence is derived from adequately detailed and reliable exploration, sampling and testing and is sufficient to assume geological and grade or quality continuity between points of observation.
An Indicated Mineral Resource has a lower level of confidence than that applying to a Measured Mineral Resource and may only be converted to a Probable Mineral Reserve.

14.15 Mineral Resource Summary
All mineral resources reported on the property include the Mount Diablo and Northern Belle pits, leach pads and low-grade stockpiles. The pits are reported at a US $9.273 NSR cut-off, underground uses a 90 g/t Ag T cut-off below the design pit and the low-grade stockpiles and leach pads are reported with no cut-off as the whole volume would be extracted. Leach pads were previously reported in 2020. (McCrea, 2020)

14.16 Reasonable Prospects for Eventual Economic Extraction
For reasonable prospects of eventual economic extraction (“RPEEE”) Silver One contracted IMC of Tuson Arizona to estimate mining and operating cost for the project and using previous metallurgical test work create a mine schedule, run a pit optimization and design a preliminary pit for resource reporting.
CIM Definition Standards for Mineral Resources and Mineral Reserves (May 10, 2014) defines a mineral resource as:
“(A) concentration or occurrence of solid material of economic interest in or on the Earth’s crust in such form, grade or quality and quantity that there are reasonable prospects for eventual economic extraction.
The location, quantity, grade or quality, continuity and other geological characteristics of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge, including sampling”.
The “reasonable prospects for economic extraction” requirement generally implies that the quantity and grade estimates meet certain economic thresholds and that the mineral resources are reported at an appropriate cut-off grade considering extraction scenarios and processing recoveries. To meet this requirement, IMC considers the Candelaria Mine amenable to open pit extraction or underground mining with a heap leach extraction method as operated in the past.
To determine the quantities of material offering “reasonable prospects for economic extraction” by a ‘pit’, IMC used a pit optimizer and reasonable mining assumptions to evaluate the proportion of the block model (Indicated and Inferred blocks) that could be “reasonably expected” to be mined from an open pit (Figure 14.11).
The optimization parameters were selected based on experience and benchmarking against similar projects (Table 14.28). The reader is cautioned that the results from the pit optimization are used solely for testing the “reasonable prospects for economic extraction” by a pit and do not represent an attempt to estimate mineral reserves. There are no mineral reserves on at

Candelaria Mine. The results are used as a guide to assist in the preparation of a mineral resource statement and to select an appropriate resource reporting cut-off grade.

Note: Process recoveries used for RPEEE are estimated true operating field recoveries. For economic study purposes, KCA recommends discounting laboratory gold extractions by two to three percentage points, and silver extractions by three to five percentage points when estimating field recoveries .
The block model quantities and grade estimates were also reviewed to determine the portions of the Candelaria Mine having “reasonable prospects for economic extraction” from an underground mine, based on parameters summarized in Table 14.29.

To fulfill the requirement of reasonable prospects for economic extraction, a conceptual crushing and leaching scenario using the Merrill-Crowe process was developed based on the results of the High-Pressure Grinding Rolls (“HPGR”) and column cyanide leach tests. These metallurgical tests were completed by McClelland Laboratories Inc. and Kappes Cassiday & Associates in Reno, Nevada (summarized in section 13).
The scenarios evaluated were developed based on operational throughputs of 10,000 tonnes per day (tpd). The base case was the 10,000 tpd option using a silver recovery of 56%, 66% and 55% for oxide, mixed and sulfide material respectively and gold recoveries of 51%, 10% and 0% for oxide, mixed and sulfide respectively.

14.17 Factors That May Affect Mineral Resource Estimate and Other Possible Risks
The mineral resource estimate is subject to numerous economic and technical assumptions. Example risks associated the mineral resource estimate may include:
-
Unknown extent of historic workings at Mt. Diablo
-
Low number of Ag and Au total assays (FA)
-
Variability in CN soluble assay methodology
-
Specific gravity estimates and assumptions
-
Price and cost assumptions
-
Recovery and processing assumptions
-
Geotechnical assumptions
-
Metallurgical samples are only from the leach pads and the Mount Diablo deposit (Lower Candelaria Shear). Samples from Northern Belle and outside the shear have not been tested by Silver One and may have different metallurgical characteristics and recovery factors.

25.0 INTERPRETATION and CONCLUSIONS
The QP has reached the following conclusions and interpretations as a result of the review of data and preparation of the technical report.:
25.1 Project Setting
The Project is located in an area of Nevada with moderate relief, good road access and other required infrastructure. Mining activities should be capable of being conducted year-round. There is sufficient suitable land area available within the mineral claims for any future pit expansions, leach pads, mine waste disposal, and installations such as a processing plant, and related mine infrastructure.
25.2 Mineral Tenure, Surface Rights, Water Rights and Royalties
Silver One acquired 100% interest in the Candelaria property from SSR Mining after issuing a total of US$3,100,000 in common shares (being 10,424,374 common shares) over a threeyear period from 2017 to 2020 and assumed an US$2,491,757 reclamation bond filed with the BLM.
The Candelaria property covers an area of approximately 8,293 ha (20,492.5 acres) and is comprised of 33 patented and 1135 unpatented federal mining claims situated on lands administered by the United States Bureau of Land Management where patented claims cover most of the immediate Northern Belle and Mount Diablo deposit areas. A 3% net smelter return royalty payable to Teck Resources USA on production from a certain claim group of the property and a charge of $0.01 per ton payable for waste rock dumped on certain claims. Several internal third-party claims are not proximal to potential future mining operations.
The QP believes there are no environmental considerations or other significant factors or risks that may affect access, title, or the right or ability to perform exploration and development work on the Property.
25.3 Geology and Mineralization
Silver-gold-lead-zinc (± Sb ±As) mineralization at Candelaria occurs primarily along thrustrelated structures including the Pickhandle thrust and the Lower Candelaria shear (“LCS”). Silver One geochemical analyses of drill core and cuttings show a close association between Ag-Au mineralization and cadmium. Subsequent weathering and oxidation of the mineralized zone occurred during the Early and Late Tertiary leaving mineralization partly to completely oxidized to a depth of 200 m.
The deposit is considered to be an example of a disseminated Ag-Au deposit hosted within sedimentary rocks and distal to a porphyry Cu deposit. The deposit type used for exploration targeting is appropriate to the mineralization identified. The deposit remains open down-dip and along strike.
Knowledge and documentation of the deposit settings, lithologies, and structural and alteration controls on mineralization are sufficient to support the Mineral Resource estimate.
25.4 Exploration, Drilling and Analytical
The exploration programs completed to date are considered appropriate to the style of the known mineralization within the Project area.

Since optioning the property in 2017, Silver One completed several surface geophysical exploration programs followed by RC and diamond drilling totalling 27,404 metres in 137 holes. Property-wide geophysical surveys have proven useful aids for interpreting deposit and regional geology and for identifying exploration drill targets.
The resource database comprises 680 historic and recent drill holes from Mount Diablo and 251 drill holes at Northern Belle with some 72,570 samples analyzed for soluble Ag and Au and 2925 recent samples which were also analyzed for total Ag by ICP or gravimetric methods and Au by fire assay and a multi-element ICP.
Total Ag and Au values were calculated by Silver One from historic drill hole soluble Ag and Au using regression formulas developed from samples reporting both cyanide soluble and total values for Ag and Au. Separate formulas were calculated for Northern Belle and Mt. Diablo and for Oxide/Mixed and Sulphide material.
Silver One maintains a robust QA/QC program that meets or exceeds industry standards. Only minor QAQC information is available for historic data; however, the data is believed to be reliable as it was used for successful mine exploration and development over a period of more than 20 years.
The drilling and assay data provided by Silver One is believed to be adequate for the purposes of this mineral resource estimate and the author has no reason to believe that any of the information is inaccurate.
25.5 Data Verification
The QP visited the subject property and area in August of 2006, on July 9th to 11th, 2018, and again on June 9th, 2023. During the 2006 site visit for Silver Standard, the author visited the two leach pads and the two open pits and collected verification samples. During the 2018 site visit the following data verifications were performed:
-
examination of sonic drill collars from the 2017 drilling program on the leach pads and the east and west low-grade stockpiles;
-
verification sampling of the two leach pads;
-
bulk densities for the leach pads were verified by comparing recorded mine production to solid model volume.
-
During the 2023 site visit the following data verifications were performed
-
examined diamond drill core and examined metallurgical sample and core storage;
-
During the preparation of this report the following data verifications were performed:
-
review of previous technical reports;
-
manual verification of data while constructing the resource database.
The QP is of the opinion that these data are adequate for the purposes used in this technical report.
25.6 Metallurgical Test Work
Prior to 2001 the Candelaria mineralization had been mined by open-pit methods and processed by heap leaching for 20 years. Historic mine recovery averaged 51% silver. During this time extensive metallurgical testing was conducted by its various operators which also includes heap leach production records.

Silver One contracted McClelland Laboratories Inc., of Sparks, NV, in 2018 and Kappes Cassiday & Associates (“KCA”) in Reno, NV, during 2018-2019 and 2022-2024, to conduct metallurgical testing on the various type of materials (leach pads and oxidized/mixed/sulphide mineralization obtained from pits and drill core). During 2023 and 2024, the Company engaged Extrakt Process Solutions (“EPS”) to conduct non-cyanide leach tests. The best column cyanide-leach silver recoveries obtained by KCA in oxide, sulfide and mixed material crushed with HPGR to 1.7 mm are 61%, 58% and 72% respectively.
Metallurgical testing has been encouraging to date and is ongoing.
25.7 Mineral Resource Estimate
Mineral Resources at Candelaria are reported separately by area: Mt. Diablo and Northern Belle open-pittable; Mt. Diablo underground; leach pads and Low-Grade Stockpiles (“LGSP”). The current resources are classified as Measured, Indicated and Inferred following CIM Definition Standards (2014) and the sample database used for the estimation is adequate for the purpose used.
The Mineral Resource estimate is based on reasonable assumptions of eventual economic extraction and assuming open pit mining method for all but the small Mt. Diablo underground resource. The in-ground Mount Diablo and Northern Belle resources use a US $9.273 NSR cut-off inside the $27.50 Ag preliminary design pit and a 90 g/t Ag T cut-off for underground with a 70% mining recovery below the design pit. The leach pad and LGSP resources are reported with a 0.01 g/t silver cut-off grade as it will be mined in their entirety with no grade control or selectivity.
The Mineral Resource estimate is based on reasonable prospects of eventual economic extraction and assuming open pit mining method with 45° pit slope for all but the small Mt. Diablo underground resource. Production scenarios evaluated were developed based on operational throughput of 10,000 tonnes per day (tpd) and using silver recoveries of 56%, 66% and 55% for oxide, mixed and sulfide material respectively and gold recoveries of 51%, 10% and 0% for oxide, mixed and sulfide respectively.
The following factors could affect the Mineral Resources: unknown volume of underground working; assumptions used to estimate Total Ag and Au values from historic CN soluble values; limited specific gravity data; commodity price and exchange rate assumptions; pit slope angles and other geotechnical factors; assumptions used in generating the constraining pit shell, including metal recoveries, and mining and process cost assumptions.
25.8 Conclusions
The exploration and development studies completed to date by Silver One support further work as detailed in Recommendations. This work includes further exploration and resource drilling; further metallurgical testwork; environmental studies and initial permitting; and initial economic studies.
Project risk factors have been documented above and throughout the report.

26.0 RECOMMENDATIONS
Given the long history of mineral production from the Property with over 68 million ounces of silver produced, existing current mineral resources that remain open in all direction as well as the property’s good exploration potential, its continued assessment is justified. A two-phase exploration program is recommended to evaluate its potential for further bulk-tonnage and undergrounds precious metal production and additional mineralization from new targets. A description of a recommended exploration program is as follows:
26.1 Proposed Exploration Budget
The recommended exploration and work programs for the Candelaria Property are as follows:
Phase I - Update Resource and Heap Leach Pads Evaluation and Project PEA
