of EVR’s near-term antimony production strategy with plant refurbishment underway, maiden drilling well advanced and geophysical surveys having commenced.
EV Resources CEO, Mike Brown, commented : “The commencement of geophysical surveys is a big step in unlocking the antimony potential of Los Lirios. CSAMT has been chosen as the most appropriate method given presence of stibnite as the dominant sulphide associated with mainly quartz. We are expecting the detailed survey over the initial high-priority prospects to provide an extremely valuable tool.
Combining findings from the survey with results from current drilling will allow us to calibrate results and establish a fingerprint we can use in immediate drill targeting, as well as establishing it as an ideal exploration tool. With nearly 5km of the highly prospective LFZ still to be tested in any detail outside of the current drilling prospects, as well as 90% of the property unexplored, this could unlock an extremely efficient and useful tool for drill targeting and antimony discovery at Lirios. Activities at Tecomatlán are progressing, which is very pleasing given the plant’s importance to our strategy of reaching near-term production.”
Geophysics Commenced to Systematically Unlock Property-Scale Potential
The Company has commenced a geophysical survey at the Los Lirios Antimony Project designed to provide systematic, property-scale mineralisation and structural data for target delineation and drill planning.
The program comprises a Controlled-Source-Audio-frequency Magnetotellurics (CSAMT) survey of 13 line kilometres (5km at Lirios 1 and 8 km over the Hormiguero and Lirios 2 areas), and a ground magnetics survey over Lirios 1 to define the structural controls governing the hydrothermal system (see Figure 1). CSAMT has been selected as the most appropriate method given the presence of stibnite as the dominant sulphide associated with quartz gangue.
The survey will cover around 1.3km of strike length over the regional LFZ, which is at least 6km in length and considered by the Company as a critical control over antimony mineralisation within a significant hydrothermal system (see Figure 1).

Figure 1 : Geophysical survey program details
The program is designed to test the responsiveness of mineralisation to this technique, with incorporation of the drilling undertaken to date allowing the Company to create a geophysical fingerprint for the antimony mineralisation at Los Lirios.
The survey will be used to establish immediate priority targets and controls at Lirios 1 and 2, and, as a scalable exploration tool deployable across the full property, significantly improving interpretation quality and exploration efficiency going forward.
More than 90% of the property remains unexplored, with nearly 5km of the highly prospective Lirios Fault Zone yet to be systematically tested, alongside multiple N-S fault systems beyond the main structure hosting Lirios 1, Lirios 2 and Hormiguero. The geophysical program is expected to materially expand the drill-ready target inventory across the project.
Combined with first pass drilling, CSAMT is expected to provide a fundamental exploration and targeting tool as EVR advances towards a maiden JORC Mineral Resource Estimate.
Drilling Progress at Lirios 1 – First Systematic Assay Results Pending
The Company has successfully completed 11 holes of the current campaign at the Lirios 1 prospect, the first systematic drill campaign at Los Lirios. The drill rig has now advanced to the Hormiguero prospect to continue the broader Los Lirios program.
The technical team is focussed on systematic core logging, cutting, and sampling at the Company’s dedicated processing facilities. Initial core observations are providing important geological data on the hydrothermal system, specifically testing Carbonate Replacement deposit (CRD) horizons and the potential of vertical conduit structures, which have significant implications for understanding deposit geometry and volume.
The Los Lirios system has returned channel samples of up to 30.2% Sb[1] at surface, with exceptional recovery characteristics confirmed in metallurgical testwork (>90% via gravity processing; 99% in initial flotation tests[2] ).
Results from the initial program will provide the first quantified subsurface intercepts from this high-grade antimony system and are expected to materially advance EVR’s understanding of the deposit, informing the path to maiden JORC Mineral Resource Estimate targeted for Q3 CY2026. Results will be released to the market following receipt by the Company.
San Miguel Vein – Near-Surface Mineralisation Confirmed
A previously unrecognised, 2m wide vein structure (designated San Miguel) was uncovered adjacent to Pit 5 at Lirios 1. The field team identified signs of alteration and brecciation in overlying calcrete (see Figure 2) and subsequent excavation exposed the structure, confirming new nearsurface antimony mineralisation at a location with no prior historical exploitation or identification. The shallow depth of the San Miguel discovery underscores the untapped potential of the Los Lirios project area and provides a drill-ready additional target.
A handheld XRF unit (pXRF) was used to support visual observations of antimony mineralisation, principally cervantite. Cervantite is a white crystalline oxide of stibnite, often directly pseudomorphing the stibnite crystals in-situ. Results are summarised in Table 1 below.
Five channel samples (856875-856879) have been submitted to the CHEMEX laboratory in Zacatecas for formal assay, with pulps to be dispatched to ALS Vancouver for verification.

Cautionary Statement: The company cautions that estimates of mineral abundance from pXRF results should not be considered a proxy or substitute for laboratory assay results where concentrations or grades are the factor for principal economic interest. Laboratory assay results are required to determine the grade of the mineralisation and any interval widths reported. Significant variation from the results presented in this announcement would be expected from laboratory analysis. The pXRF results support the visual estimates, validating the identification of cervantite being present as an antimony oxide.
Tecomatlán Refurbishment Update – Production Path on Track
The Tecomatlán Processing Plant is the cornerstone of EVR's near-term production strategy, providing a gravity-based antimony concentrator at low capital cost, eliminating the need to build processing infrastructure from scratch and dramatically compressing the timeline and capital requirement to first antimony production. Located just 50km from the Los Lirios Project in the Oaxaca region, Tecomatlán provides a dedicated, low-cost processing hub for EVR’s North American antimony supply strategy.
The refurbishment contractor has commenced a 5-week program to commission the critical grinding circuit, rehabilitating three previously installed, but never used, ball mills ahead of dry commissioning. Machining and assembly of steel formwork and frames is underway and the electrical circuitry and 440V backbone are being assembled for installation. The program is advancing on track, with EVR targeting operational readiness during 2H2026.
The milestone-based payment structure underpinning the plant agreement continues to align EVR's capital deployment with value delivery — a disciplined approach that protects shareholder capital at every step of the refurbishment.

Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections)
| Criteria | JORC Code Explanation | Commentary |
| Sampling techniques | • Nature and quality of sampling (eg cut channels, random chips, or specifc 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 fre 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 |
• Channel sampling was conducted perpendicular to Antimony-Quartz-Calcite Veins and where mineralisation style was strata bound the sampling was conducted perpendicular to bedding to represent true width of the target strata. Pits were not always accessible or safe but sampling is considered suitably representative. • Channels were between 0.35cm to 100cm long, 10cm wide, and 3cm deep. Surfaces were cleaned prior to sampling. The channels were cut with a diamond handheld motorised saw. • The samples were collected and bagged and labelled, ranging from 2.5-5.5kg samples. • Sampling avoided over or under representation of soft/hard mineral phases. |

Expiry Date 16/05/2061. • (2) El Lirio De Los Valles 2. Title Number 244715. Area742 Hectares. Expiry Date 10/12/2065. • (3) El Lirio De Los Valles 3. Fraccion 1 Title Number 246947. Area410 Hectare. Expiry Date 30/11/2065. • The three licences are located in the Zapotitlan Laguna District of Oaxaca State in Mexico. All three licences are held by Mrs. Aleida and Mr. Dante Martinez. EVR entered into Definitive Agreement to acquire 70% of these licences and form a JV company to hold 100% of the titles. EVR, through its local subsidiary Stibcorp, is the operator of the JV. • Lirios 1 is subject to an appeal for nullification by EVR against the Directorate General de Minas (DGM), who have commenced a cancellation process on Lirios 1. This was unlawful as the current owner was not legally notified of such process, as required by the Mining Code. This is now subject to a Judicial appeal process that the Company is actively pursuing. • There are no royalties, and no known impediments to obtaining a licence to operate in the area. |

The Los Lirios Antimony Project is located within the Northern part of the Mixteca Terrane. The Mixteca Terrane is one of the numerous identifed accretionary “exotics”, distinct rock units or terranes, postulated by “Monger and Davis in 1982”. More than 75 terrranes have been identifed, stretching from Southern Alaska to Chiapas State of the Mexico Republic. The accretionary process began in Early Jurassic Epoch, about 200 million years ago. In short, most of the entire Western North America Margin from Alaska to Chiapas in Mexico is a big geological and structural jigsaw puzzle. The boundaries of these terranes have acted as conduits for mineralizing fuids that have resulted in the development of an enormous number of precious and base metal deposits.

Development of the Los Lirios Antimony (Sb) mineralization is hosted in Middle and Upper Jurassic Limestone, |
Conglomerate, and Shales on anticlines and shear zones. Los Lirios Antimony ( Sb ) mineralization paragenesis is formed by Stibnite in Chalcedony and Calcite Gangue. Minor Pyrite observed disseminated in the Chalcedony. It is common to find the Stibnite ( Sb2S3 ) altered to Stibiconite Sb[3+] Sb[5+] 2 O 6( OH ) and other Antimony Hydroxides . This is clearly evident in the shear zones, being exploited on a small scale, near the village of Guadalupe Buenos Aires. This shear zone measures at least 180m in length and 70m wide. A parallel shear zone on the opposite side of the same small ridge indicates that the potential depth of mineralization in these shear zones may exceed more than 250m. More than 7km NW of Guadalupe Buenos Aires Shear Zone a series of stacked shear zones measuring over 110m in length and 60m wide are developed on a flat lying ridge northwest of Cerro Pajarito in El Lirio De Los Valles 1 concession (Los Lirios 1). The mineralisation model from mapping and sampling to date suggests that the primary control for mineralising fluids were subvertical N-S faults, trending from 0 to 15 degrees. These have preferentially developed along or near anticlinal axis, with weak silicification observed in the limestones along with crackle brecciation along the axis. The presence of W to NW trending cross cutting faults at LZ1, LZ2 and Hormigueros suggests these structures played a crucial role in concentrating mineralising fluids and likely provided
| additional open space for the quartz-stibnite mineralisation to precipitate. Strong to moderate silicification envelops the mineralised structures. This structurally controlled mineralisation is considered by EVR as the principal mineralisation target for exploration. The presence of carbonate replacement mineralisation beneath a capping gypsum layer at LZ1 and LZ2 suggests that the gypsum acted as a cap-seal for fluids within the faults forcing them out into specific limestone units, where typical carbonate replacement textures are observed, including veinletting. These limestone units are shallow dipping, with mineralisation observed to extend laterally along these units from vertical feeder structure. They provide a second significant mineralisation target and may have important impact on potential volume for the Project. • No drilling is being reported. |

| 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: • easting and northing of the drill hole collar • elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar • dip and azimuth of the hole • down hole length and interception depth • hole length. • If the exclusion of this information is justifed on the basis that the information is not Material and this |
• No drilling is being reported. |
| • No data aggregation has been applied to the results. • Channel sample widths are representative of true thickness. |

|---|---|---|---|
| exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
|||
| Data aggregation methods |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g., 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 has been applied to the results. | |
| 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’). |
• Channel sample widths are representative of true thickness. |
| • Diagrams in the report include location maps, regional maps and detailed project area maps. These provide an adequate visual representation of the exploration areas. • The reports provide a balanced presentation of early stage geological observations with sample data reported in full. • No selective reporting was used that could misrepresent the overall results. • All available samples and results have been disclosed. • Geological mapping of the pits was conducted prior to sampling. • A representative bulk sample taken from 3 samples was used for preliminary metallurgical testing. Results indicated mineralisation at surface had very low level to negligible impurities, with mineralisation almost entirely antimony (in the form of stibnite and cervantite). These were reported (see ASX Release 16 December, 2025). |

| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any signifcant discovery being reported. These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
• Diagrams in the report include location maps, regional maps and detailed project area maps. These provide an adequate visual representation of the exploration areas. |
|
| 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 reports provide a balanced presentation of early stage geological observations with sample data reported in full. • No selective reporting was used that could misrepresent the overall results. • All available samples and results have been disclosed. |
|
| Other substantive exploration data |
• Other exploration data, if meaningful and material, should be reported including (but not limited to): geologicalobservations; geophysical surveyresults; 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. |

• EV Resources is planning to extend reconnaissance mapping and geophysical surveys to other areas on the 3 tenements. Principal targets are the intersection of W to NW structures with principal N-S fault system preferentially developed on anticline axis of gently folded carbonate units. There appear to be at least 2 of these N-S fault systems on the claims not including the main system on which LZ1, LZ2 and Hormigueros are located.
