HIGH-GRADE GOLD SAMPLING RESULTS CONFIRM POTENTIAL AT BAYAN SPRINGS PROJECTS, NEVADA

Highlights

Rock chip sample from the Bayan Springs South Project returned an outstanding assay of 4.56 g/t Au (Sample No. 19093, refer to Appendix 2) , confirming potential for hosting Carlin type mineralisation system.
Elevated levels of key pathfinders, including arsenic (up to 2,640 ppm) and antimony (up to 863 ppm) (Sample No. 19088 & 19073 respectively, refer to Appendix 2) , further support a robust Carlin-type geochemical footprint.
Gold mineralisation is spatially associated with jasperoid alteration at key structural and lithological contacts, similar to the nearby Bald Mountain gold deposit (~10 km to the south).
At Bayan Springs North, elevated arsenic, antimony, and zinc values were identified near granitic intrusions and rhyolite dykes from the same stratigraphic sequence that host Maverick Springs mineralisation warranting further follow-up.
Soil samples from Bayan Springs North returned up to 171.5 ppm arsenic, 0.13 ppm mercury, 8.29 ppm antimony, and 0.74 ppm thallium (refer to Appendix 4) , representing pathfinder element concentrations considered anomalous for Carlin-style systems (Cline et al., 2005; Hofstra & Cline, 2000; Radtke, 1985).

Bayan Mining and Minerals Ltd (ASX: BMM; "BMM" or "the Company") is pleased to announce the successful completion of a reconnaissance prospecting and geochemical sampling program at its 100% owned Bayan Springs Project in north-eastern Nevada, USA. The program has confirmed the presence of multiple gold-arsenic-antimony anomalous zones consistent with Carlin-style mineralisation and generated several compelling targets for follow-up work.

Executive Director Fadi Diab commented:

“These results strongly validate our exploration model and highlight Bayan Springs as an emerging Carlin-style gold system. The high-grade assays, supported by classic pathfinder elements and structural controls, confirm the project’s potential. Notably, our recent findings which show geological analogy to the Bald Mountain deposit, located just 10 kilometres to the south, which hosts mineralisation within the same stratigraphic sequence further support the prospectivity of Bayan Springs South. This alignment provides a compelling analogue and reinforces our confidence that the system we’re exploring may be part of a broader, mineralised corridor. We are excited to move into the next phase of work, which will include systematic sampling and geophysics to refine and potential drill targets.”

ASX ANNOUNCEMENT 15 May 2025

During recent reconnaissance prospecting and geochemical sampling across the Bayan Springs Project in north-eastern Nevada, the Company identified multiple zones of anomalous gold and pathfinder elements. The program, covering both the Bayan Springs South and Bayan Springs North project areas, was designed to assess the project’s potential to host significant gold and silver mineralisation. Fieldwork focused on verifying key geological features, characterising alteration related to the targeted style of mineralisation styles, and identifying geochemical signatures indicative of Carlin-style gold systems. The results will guide and prioritise the next phase of exploration.

At Bayan Springs South, a total of 47 rock chip samples were collected, primarily from outcropping jasperoid and structurally favourable carbonate horizons. Standout results include assays of 4.56 g/t Au, 2640 ppm As, and 863 ppm Sb, representing a robust Carlin-style geochemical signature. Refer to Appendix 1 for sample locations and to Appendix 2 for detailed assay results.

Importantly, the geology, stratigraphy, and pathfinder suite observed at Bayan Springs closely resemble those at the nearby Bald Mountain mine (operated by Kinross Gold Corporation (NYSE:KGC)), located just 10km south. According to Nutt and Hofstra (2007), stratabound mineralisation at Bald Mountain is primarily hosted within Palaeozoic carbonate formations, notably the Dunderberg Shale, Hamburg Dolomite, Secret Canyon Shale, and Eldorado Dolomite lithologies that are also present at the Bayan Springs South Project. These formations have been deformed by folding and thrusting, with gold mineralisation commonly localised along thrust faults, high-angle structures, and at stratigraphic contacts. Alteration styles include decalcification, jasperoid development, silicification, and argillisation, which are hallmark features of Carlin-type gold systems.

Bald Mountain contains multiple mineralised zones (camps) across its extensive project area, with several deposits showing strong geological affinity to Bayan Spring South targets. In both projects, thrust contacts between the Hamburg Limestone and Secret Canyon Shale have formed important structural and chemical traps for mineralising fluids. The presence of jasperoid in both locations underscores a shared alteration signature. Additionally, while portions of Bald Mountain host intrusive-related mineralisation, the dominant ore controls remain stratigraphic and structural closely aligning with the model at Bayan Springs South.

alteration styles, and mineralisation patterns highlight Bald Mountain as a robust regional analogue target model for the Bayan Springs South project. Further supporting this comparison, Nutt and Hofstra (2007) describe multiple mineralised centres (camps) at Bald Mountain (e.g., Saga, Winrock, Top, Alligator Ridge, and Badger) that are localised along key lithological contacts and structural intersections. These centres often occur within or adjacent to jasperoid-altered zones, especially along thrust faults involving the Dunderberg Shale and Hamburg Dolomite, as well as the basal units of the Eldorado Dolomite and Secret Canyon Shale units that are directly correlative with those mapped at Bayan Springs South.

At Bayan Springs North, reconnaissance prospecting and sampling identified geochemical anomalies supportive of further exploration. The highest arsenic value of 798 ppm and zinc value of 711 ppm were recorded in the northern claim block, particularly near the contact zone of a Cretaceous-aged granitic intrusion and rhyolite dykes from the same stratigraphic sequence that host Maverick Springs mineralisation. These results, coupled with observed hydrothermal alteration, highlight the potential for structurally controlled mineralisation and warrant follow-up work, including detailed mapping and soil sampling.

About Bayan Spring North Project

The Bayan Spring North project consists of 116 lode claims covering approximately 9.7 km[2] . It is adjacent to Sun Silver Ltd (ASX:SS1) Maverick Springs Project, which holds a JORC 2012 Inferred Mineral Resource of approximately 218.5 million tonnes at 68.29g/t AgEq, contained 480Moz AgEq[1] .

The project is located in the Northern Maverick Springs Range, south Elko County and north White Pine County, Nevada, USA. It is located approximately 85 km

south of Elko and 105 km to the north-northwest of Ely. The Project area is accessible by paved Lamoille Highway and Harrison Pass Road to Ruby Valley from where is accessible by a well-maintained gravel road.

The primary hosts for silver and gold mineralisation are the silty limestone and fine-grained calcareous clastic sediments of the Rib Hill Formation. These formations are exposed over a remarkable 40 km stretched zone, striking north north-westerly.

Felsic to intermediate intrusive centres outcropping south and north of the project area are interpreted to have acted as feeder systems for Tertiary volcanic flows, potentially influencing the migration of mineralising fluids into surrounding favourable host environment.

Regionally, the project area lies within the tectonically active Great Basin province and in proximity to the Carlin Trend, a significant structural feature that demarcates a deep-seated fault. This fault line separates thicker, stable continental crust to the east from a zone of thinned, transitional crust to the west, providing structural conduits favourable for migration, concentration and deposition of gold and silver mineralisation. Historical exploration in this geologic setting reveals structural trends and faulting that may play a role in localising mineralisation within the project area.

Locally, the project area lies within a geologically diverse region dominated by carbonate formations that record a history of continental margin sedimentation. These include limestones and dolostones of the Permian-Pennsylvanian Rib Hill Formation, limestones of the Permian Pequop Formation, and carbonate strata of the Permian Park City Group. Locally, these sedimentary units have been intruded by Jurassic and Cretaceous acidic to intermediate, biotitic igneous rocks, and subsequently overlain by Tertiary volcanic deposits, including rhyolites and Late Tertiary tuffs.

This region’s combination of carbonate-rich sedimentary units and structural complexity makes it permissive for sediment-hosted gold and silver mineralisation. Carbonate rocks, especially in proximity to intrusive bodies, often provide chemically reactive settings conducive to metal deposition. The presence of deep-seated faults, proximity to the Carlin Trend, also facilitates the movement of mineralising fluids through these permeable carbonate units, increasing the likelihood of significant mineral accumulation. Collectively, these geological factors create a favourable environment for discovering substantial sediment-hosted precious metal deposits.

About Bayan Spring South Project

The Bayan Spring South Project is located along the prolific Carlin Trend and consists of 42 lode claims covering an area of approximately 3.75 km[2] . The Project is located east of Bellview Au-Ag-Pb Deposit[2] and approximately 10 km north of Kinross Gold Corporation (NYSE:KGC) Bald Mountain mine, a major gold mining operation in Nevada with approximately 1.173 million ounces in Probable Reserves, 2.7 million ounces in Measured and Indicated Resources and 571 kilo ounces in Inferred Resources (as of 31 December 2024)[3] .

The project is situated on the southern slopes of the Ruby Mountains in northwest White Pine County, Nevada, USA, approximately 85 km south of Elko and 110 km northwest of Ely. The project area is accessible via the paved Lamoille Highway and Harrison Pass Road leading to Jiggs, with a well-maintained gravel road providing direct access to the site.

Geologically, the project is located within southern extension of the prolific Carlin trend. The broader project area is characterised by a conformable sequence of Cambrian limestones, dolomites, shales, quartzites, siltstones, and altered jasperoids, which generally dip to the SSE.

Lower to Middle Cambrian sedimentary sequences, including limestones, dolostones (notably the Eldorado Dolomite), and shales of the Secret Canyon and Dunderberg Formations. These units are structurally juxtaposed along a complex network of northeast- and northwest-trending faults and thrusts. A swarm of dioritic dikes intrudes the sequence, and major faults exhibit north-northeast, northwest, and east-west orientations. A prominent regional thrust fault emplaces the Cambrian Hamburg Limestone above the Secret Canyon Shale, creating a structural trap exploited at the Saddle Target. The stratigraphy is folded into a doubly plunging anticline, further deformed by additional WNW- and NE-trending warps. High-angle faults have played a key role in localising jasperoid alteration, which acts as a critical control on Carlin-type gold mineralization.

Criteria	JORC Code explanation	Commentary
*Sampling* *techniques*	• Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information.	• Soil samples were collected from “B” horizon while rock chips from outcrops. The samples were taken randomly with sites located by a handheld GPS. • Samples varied in weight from 0.38 kg to 1.5 kg, and with an average weight of 0.63 kg per sample. • All collected soil samples for the present study were prepared in ALS Reno and partly analysed by ALS Reno and partly by ALS Vancouver, ALS is ISO 9001:2015, and ISO 14001:2015 certified lab. • QAQC monitoring was achieved through the submission and monitoring of standard reference materials, duplicates and blank samples.
*Drilling* *techniques*	• Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc).	• No drilling results are being reported.
*Drill sample* *recovery*	• Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.	• No drilling results are being reported.

Criteria	JORC Code explanation		Commentary
*Mineral* *tenement and* *land tenure* *status*	• Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. • The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.		Bayan Springs North • Bayan Springs North is located in the Northern Maverick Springs Range, south Elko County and north White Pine County, Nevada, USA. It is located approximately 85 km south of Elko and 105 km to the north-northwest of Ely. The project consists of 116 NMS unpatented lode mining claims registered with the US Department of the Interior Bureau of Land Management (“BLM”) with a total area of approximately 9.7 km2. Bayan Springs South • Bayan Springs North is located in the Southern slopes of the Ruby Mountains north White Pine County, Nevada, USA. It is located approximately 85 km south of Elko and 110 km to the northwest of Ely. The project consists of 45 NMS unpatented lode mining claims registered with the US Department of the Interior Bureau of Land Management (“BLM”) with a total area of approximately 3.75 km2.
*Exploration* *done by other* *parties*	• Acknowledgment and appraisal of exploration by other parties.		• There is no evidence that any systematic exploration has been conducted within the current boundaries of the Bayan Springs North Project. • Bayan Springs South Project, previously known as Bellview property (much wider area then Bayan Springs South Project area) has been extensive exploration more than 70 years. Below is a timeline of the major activities and companies involved that : • 1951–1954: Unknown operators mined small Pb- Ag prospects over Bellview Area (reported grades ~10% Pb and 1 oz/ton Ag). • 1970: Prospectors Kohlmoos and Zilich staked claims for gold. • 1979–1985: Arctic Precious Metals Inc. optioned the property. Work included soil and rock geochemistry, VLF-EM geophysics, detailed mapping, and 95 reverse circulation (RC) drill holes (~15,557 ft / 4,741 m). Arctic outlined a non- compliant resource of ~500,000 tons @ 0.034 oz/ton Au (≈1.17 g/t). • 1980s (unknown date): Geologist Lyle Campbell reportedly drilled ~20 RC holes in the Cherry Springs area, but results were not recorded. • 1986: Silver State Mining Co. drilled 10 shallow vertical RC holes (1,105 ft / 336 m) as infill in the resource area. • 1987: Pegasus Gold Inc. conducted rock chip and soil sampling over jasperoid zones. • 1987–1991: Teck Resources Limited undertook the most significant drilling program, completing 68 RC holes (~10,630 ft / 3,240 m). Teck’s work focused on the “resource zone,” and they calculated a historical (non-NI43-101) resource of 1.12 million tons @ 0.031 oz/ton Au (~0.96 g/t) containing ~34,720 oz Au. This resource lies in the basal Secret Canyon Formation above the Eldorado Dolomite. • 1991–1999: Western States Minerals Corp. drilled 26 RC holes (3,598 m) in several campaigns, and conducted additional mapping, rock-chip

			sampling, and soils geochemistry. • 1996: Homestake Mining Co. drilled 6 RC holes (2,835 ft / 864 m), testing geophysical and conceptual deeper targets beyond the known resource. • 2006–2010: Fronteer Gold (via its subsidiary Nevada Eagle) acquired Bellview. Fronteer compiled all historic data into a GIS database and carried out further field studies, including mapping and sampling. By 2010, Fronteer geologists developed three drill-ready target zones (Saddle, Cherry Springs, and CS) based on the new interpretation. • 2010–2011: Bridgeport Ventures Inc. acquired the Bellview property (and other Nevada projects) from Fronteer in October 2010. Bridgeport’s QP (Dr. Gray) prepared a NI 43-101 technical report (the “Nevada Report”) summarizing the project. No new drilling or exploration by Bridgeport had commenced as of the 2011 filings, but drilling permits were initiated and the property was considered “drill-ready”. • This rich exploration history (including a total of ~225 drill holes reported on the property from which mostly are on Bellview Project) established a solid geological model and identified high-priority targets. Teck’s historical resource (~0.96 g/t Au) provides a benchmark for the gold endowment, while Fronteer/Bridgeport’s work refocused efforts on new target areas (Saddle, Cherry Springs, and CS) with potential for higher-grade mineralization which are within Bayan Springs South project area. • The company is actively working on retrieving those historical results.
*Geology*	• Deposit type, geological setting and style of mineralisation.		Bayan Springs North • The project area lies within a geologically diverse region dominated by carbonate formations that record a history of continental margin sedimentation. These include limestones and dolostones of the Permian-Pennsylvanian Rib Hill Formation, limestones of the Permian Pequop Formation, and carbonate strata of the Permian Park City Group. Locally, these sedimentary units have been intruded by Jurassic and Cretaceous acidic to intermediate, biotitic igneous rocks, and subsequently overlain by Tertiary volcanic rocks, including rhyolites and late Tertiary tuffs. This region’s combination of carbonate-rich sedimentary units and structural complexity makes it permissive for sediment-hosted silver, gold and antimony mineralisation. Carbonate rocks, especially in proximity to intrusive bodies, often provide chemically reactive settings conducive to metal deposition. The presence of deep-seated faults also facilitates the movement of mineralising fluids through these permeable carbonate units, increasing the likelihood of significant mineral accumulation. Collectively, presences of those geological factors within Bayan Springs North project area create a favourable environment for discovering substantial sediment-hosted precious metal deposits.

			Bayan Springs South • This region, on the western slope of the Ruby Mountains, hosts much older stratigraphy which generally strikes north south and dips shallowly to moderately to the east. • The geology is dominated by Lower to Middle Cambrian sedimentary sequences, including limestones, dolostones (notably the Eldorado Dolomite), and shales of the Secret Canyon and Dunderberg Formations. These units are structurally juxtaposed along a complex network of northeast- and northwest-trending faults and thrusts. A swarm of dioritic dikes intrudes the sequence, and major faults exhibit north- northeast, northwest, and east-west orientations. A prominent regional thrust fault emplaces the Cambrian Hamburg Limestone above the Secret Canyon Shale, creating a structural traps. • The stratigraphy is folded into a doubly plunging anticline, further deformed by additional WNW- and NE-trending warps. High-angle faults have played a key role in localizing jasperoid alteration, which acts as a critical control on Carlin-type gold mineralization. • The Bald Mountain deposit, located approximately 10 km south of Bayan Springs South, shares key geological features with the Bayan Springs Project area and provides a meaningful geological analog. According to Nutt and Hofstra (2007), stratabound mineralization at Bald Mountain is primarily hosted within Paleozoic carbonate formations, notably the Dunderberg Shale, Hamburg Dolomite, Secret Canyon Shale, and Eldorado Dolomite lithologies that are also present at the Bayan Springs South Project. These formations have been deformed by folding and thrusting, with gold mineralization commonly localized along thrust faults, high-angle structures, and at stratigraphic contacts. Alteration styles include decalcification, jasperoid development, silicification, and argillization, which are hallmark features of Carlin-type gold systems.
*Drill hole* *Information*	• A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: `o` easting and northing of the drill hole collar `o` elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar `o` dip and azimuth of the hole `o` down hole length and interception depth `o` hole length. • If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.		• No drilling results are being reported.

*Data* *aggregation* *methods*	• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated.	• No data aggregation is being used.
*Relationship* *between* *mineralisation* *widths and* *intercept* *lengths*	• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’).	• No drilling results are being reported.
*Diagrams*	• Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.	• Appropriate figures showing sample locations and list of samples with its coordinates and assays values were included in the main body of this announcement.
*Balanced* *reporting*	• Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.	• The announcement is believed to include all representative and relevant information and is believed to be comprehensive.
*Other* *substantive* *exploration* *data*	• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.	• All relevant and material historical exploration data related to the project area is discussed, have been reported or referenced.
*Further work*	• The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large- scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.	• Further work will include but not limited to retrieving of historical data, data compilation and interpretation, systematic rock chip and soil sampling, geophysics survey, structural interpretation, permitting and drilling.
