Mithril Intercepts High-Grade Silver At Target 5 Returning 1,714 G/T AGEQ (5.8 G/T AU, 1,308 G/T AG) Over 1.0 M At The Copalquin District, Mexico

(via TheNewswire) Melbourne, Australia and Vancouver, Canada – November 5, 2025 – TheNewswire - Mithril Silver and Gold Limited ("Mithril” or the "Company") (TSXV: MSG) (ASX: MTH) (OTCQB: MTIRF) is pleased to provide exploration results and update for multiple targets at Mithril’s district scale Copalquin property, Durango State, Mexico. High-grade intercepts returned from initial drilling at Target 5,  a new, silver rich target in the southwest area of the Copalquin District at lower elevation within the large Copalquin epithermal gold-silver system – with results up to 100 metres below surface near the historic El Apomal mine; only ~5% of the mapped and projected vein system has been tested to date.   Target 5 highlights include   2 .75 m @ 660 g/t AgEq 1 ( 2.28 g/t gold, 500 g/t silver) from 93.6 m (AP25-003), including   1.00 m @ 1,714 g/t AgEq ( 5.80 g/t gold, 1,308 g/t silver) from 94.7 m 3.35 m @ 366 g/t AgEq ( 1.71 g/t gold, 246 g/t silver) from 90.15 m (AP25-005), including   1.05 m @ 1,146 g/t AgEq ( 5.35 g/t gold, 771 g/t silver) from 92.45 m 1.25 m @ 728 g/t AgEq ( 4.55 g/t gold, 409 g/t silver) from 119.2 m (AP25-006), plus   0.90 m @ 616 g/t AgEq ( 2.41 g/t gold, 447 g/t silver) from 138.1 m, plus 0.80 m @ 427 g/t AgEq ( 1.51 g/t gold, 321 g/t silver) from 149.5 m Target 5 Drilling is progressing rapidly, with 13 drill holes now completed. Assays have been received for the first eight holes which have all returned reportable mineralised intercepts. Ongoing mapping and channel sampling continues to expand this large target area.   Tasolera Mine area at Target 5 - drilling commences this week following up high-grade channel sampling, including 3,440 g/t AgEq (2.0 g/t gold, 3,300 g/t silver) 2 over 1.40m at this highly prospective area of Target 5.   Target 3 – preparations continue for drilling in the coming months, with further channel sample results pending and the addition of a third rig.  Target 3 is a large and highly prospective gold-silver area with multiple high-grade surface samples returned to date and extensive veins mapped.   “Our maiden drill program at Target 5 is off to an excellent start, delivering multiple high-grade gold-silver intercepts from this new, silver-rich target in the southwest of the Copalquin District,” said John Skeet, Managing Director & CEO. “Assays received for the first eight of thirteen holes all returned reportable mineralisation, confirming the strength of this emerging target — and our work here has just begun with only five percent of the mapped and projected veins tested to date to just 100 metres below surface.”   “Target 5 is rapidly emerging as a major new silver-dominant zone within the broader Copalquin epithermal system where drilling continues, with holes at the high-grade Tasolera mine area commencing this week.  At the same time, Mithril continues to advance Target 3 to drill readiness with ongoing mapping and sampling, while at Target 1 drilling is testing the western extension of the maiden resource area toward the El Gallo mine, 900 metres to the west.”   District Outlook Mithril is fully funded to complete 45,000 metres of drilling through to the second half of 2026, with preparations to add a third drill rig in early 2026 at Target 3. Target 1 drilling continues to focus on expanding the current resource area in the district and drilling is well underway at Target 5.  Detailed mapping and sampling also continue to advance across multiple targets, underpinning the district-scale potential of Copalquin.  A closely spaced aerial magnetic survey will be flown late 2025 and a petrographic fluid inclusion study on samples across the district is supporting the ongoing development of the district scale model for this large epithermal gold-silver system. COPALQUIN GOLD-SILVER DISTRICT, DURANGO STATE, MEXICO With 100 historic underground gold-silver mines and workings plus 198 surface workings/pits throughout 70km 2 of mining concession area, Copalquin is an entire mining district with high-grade exploration results and a maiden JORC resource. To date there are several target areas in the district with one already hosting a high-grade gold-silver JORC mineral resource estimate (MRE) at the Target 1 area (El Refugio-La Soledad) 3  and a NI 43-101 Technical Report filed on SEDAR+, supported by a conceptional underground mining study completed on the maiden resource in early 2022 and metallurgical test work (see ASX Announcement 25 February 2022 ). There is considerable strike and depth potential to increase the resource at El Refugio and at other target areas across the district, plus the underlying geologic system that is responsible for the widespread gold-silver mineralisation. With the district-wide gold and silver occurrences and rapid exploration success, it is clear the Copalquin District is developing into another significant gold-silver district like the many other districts in this prolific Sierra Madre Gold-Silver Trend of Mexico.

The district is within the Sierra Madre Gold Silver Trend which extends north-south along the western side of Mexico and hosts many gold and silver districts.   Multiple mineralisation events, young intrusives thought to be system-driving heat sources, widespread alteration together with extensive surface vein exposures and dozens of historic mine workings, identify the Copalquin mining district as a major epithermal centre for Gold and Silver.   Within 15 months of drilling in the Copalquin District, Mithril delivered a maiden JORC mineral resource estimate demonstrating the high-grade gold and silver resource potential for the district. This maiden resource is detailed below (see ASX release 17 November 2021 ) ^ and a NI 43-101 Technical Report filed on SEDAR+   Indicated 691 kt @ 5.43 g/t gold, 114 g/t silver for 121 ,000 oz gold plus 2,538,000 oz silver   Inferred 1,725 kt @ 4.55 g/t gold, 152 g/t silver for 252 ,000 oz gold plus 8,414,000 oz silver   (using a cut-off grade of 2.0 g/t AuEq*) 28.6% of the resource tonnage is classified as indicated   Table 3  Mineral resource estimate El Refugio – La Soledad using a cut-off grade of 2.0 g/t AuEq*   Tonnes (kt) Tonnes (kt) Gold (g/t) Silver (g/t) Gold Eq.* (g/t) Gold (koz) Silver (koz) Gold Eq.* (koz) El Refugio Indicated 691 5.43 114.2 7.06 121 2,538 157   Inferred 1,447 4.63 137.1 6.59 215 6,377 307 La Soledad Indicated - - - - - - -   Inferred 278 4.12 228.2 7.38 37 2,037 66 Total Indicated 691 5.43 114.2 7.06 121 2,538 157   Inferred 1,725 4.55 151.7 6.72 252 8,414 372   *  In determining the gold equivalent (AuEq.) grade for reporting, a gold:silver price ratio of 70:1 was determined, using the formula: AuEq grade = Au grade + ((Ag grade/70) x (Ag recovery/Au recovery)). The metal prices used to determine the 70:1 ratio are the cumulative average prices for 2021: gold USD1,798.34 and silver: USD25.32 (actual is 71:1) from  kitco.com .   For silver equivalent (AgEq.) grade reporting, the same factors as above are used with the formula AgEq grade = Ag grade + ((Au grade x 70) x (Au recovery/Ag recovery)) At this early stage, the metallurgical recoveries were assumed to be equal (93%). Subsequent preliminary metallurgical test work produced recoveries of 91% for silver and 96% for gold (ASX Announcement 25 February 2022) and these will be used when the resource is updated in the future.   In the Company’s opinion there is reasonable potential for both gold and silver to be extracted and sold. ^ The information in this report that relates to Mineral Resources or Ore Reserves is based on information provided in the following ASX announcement: 17 Nov 2021 - MAIDEN JORC RESOURCE 529,000 OUNCES @ 6.81G/T (AuEq * ), which includes the full JORC MRE report, also available on the Mithril Resources Limited Website.

1   Section 1 Sampling Techniques and Data   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 representativity 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.  Drill core samples are cut lengthwise with a diamond saw. Intervals are nominally 1 m but may vary between 0.5 m to 1.5 m based on geologic criteria.  The same side of the core is always sent to sample (left side of saw).  Reported intercepts are calculated as either potentially underground mineable (100m down hole) or as potentially open-pit mineable (near surface).  Potentially underground mineable intercepts are calculated as length weighted averages of material greater than or equal to 1 g/t AuEQ_70 allowing up to 2m of internal dilution.  Potentially open-pit mineable intercepts are calculated as length weighted averages of material greater than or equal to 0.25 g/t AuEQ_70 allowing for up to 2m of internal dilution.  Rock Sawn Channel samples underground and surface are collected with the assistance of a handheld portable saw. The channels are 2.5 to 3cm deep and 6-8 cm wide along continuous lines oriented perpendicular to the mineralized structure. The samples are as representative as possible   Rock Sawn Channel surface samples were surveyed with a Handheld GPS then permanently mark with an aluminium tag and red colour spray across the strike of the outcrop over 1 metre. Samples are as representative as possible  Rock Sawn Channel underground samples were located after a compass and tape with the mine working having a surveyed control point at the portal, then permanently marked with an aluminium tag and red colour spray oriented perpendicular to the mineralized structure. Samples are as representative as possible  Soil sampling has been carried out by locating pre-planned points by handheld GPS and digging to below the first colour-change in the soil (or a maximum of 50 cm). In the arid environment there is a 1 – 10 cm organic horizon and a 10 – 30 cm B horizon above the regolith. Samples are sieved to -80 mesh in the field. Samples are collected on a 20 m x 50 m grid or every 20 m on N–S lines 50 m apart. These samples are considered representative of the medium being sampled and lines are appropriately oriented to the nearly E–W structural trend.  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).  Drilling is done with MP500 man-portable core rigs capable of drilling HQ size core to depths of 350-400m (depending on ground conditions), reducing to NQ size core for greater depths. Core is recovered in a standard tube.  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.  Drill recovery is measured based on measured length of core divided by length of drill run.  Recovery in holes CDH-001 through CDH-025 and holes CDH-032 through CDH-077 was always above 90% in the mineralized zones. Detailed core recovery data are maintained in the project database.  Holes CDH-026 through CDH-031 had problems with core recovery in highly fractured, clay rich breccia zones.  There is no adverse relationship between recovery and grade identified to date.  Logging Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies.  Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography.  The total length and percentage of the relevant intersections logged.  Geotechnical and geological   logging of the drill core takes place on racks in the company core shed.  Core samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies.    Core logging is both qualitative or quantitative in nature. Photos are taken of each box of core before samples are cut. Photos of cut core intervals are taken after sampling. Core is wetted to improve visibility of features in the photos.  All core has been logged and photographed.   Rock sawn channel samples are marked, measured and photographed at location  Soil samples are recorded at location, logged and described  Sub-sampling techniques and sample preparation If core, whether cut or sawn and whether quarter, half or all core taken.  If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry.  For all sample types, the nature, quality and appropriateness of the sample preparation technique.  Quality control procedures adopted for all sub-sampling stages to maximise representativity of samples.  Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling.  Whether sample sizes are appropriate to the grain size of the material being sampled.  Core is sawn and half core is taken for sample.    Samples are prepared using ALS Minerals Prep-31 crushing, splitting and pulverizing. This is appropriate for the type of deposit being explored.    Visual review to assure that the cut core is ½ of the core is performed to assure representativity of samples.    Crushed core duplicates are split/collected by the laboratory and submitted for assay (1 in 30 samples)  Sample sizes are appropriate to the grain size of the material being sampled.  Rock sawn channel samples and soil samples are prepared using ALS Minerals Prep-31 crushing, splitting and pulverizing. This is appropriate for the type of deposit being explored.    Quality of assay data and laboratory tests The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total.  For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc.  Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established.  Samples are assayed for gold using ALS Minerals Au-AA25 method a 30 g fire assay with an AA finish. This is considered a total assay technique.    Samples are assayed for silver using ALS Minerals ME-ICP61 method. Over limits are assayed by silverOG63 and silverGRAV21. These are considered a total assay technique.  Standards and blanks are inserted at a rate of one per every 25 samples and one per every 40 samples, respectively.  Pulp duplicate sampling is undertaken for 3% of all samples (see above).  External laboratory checks will be conducted as sufficient samples are collected. Levels of accuracy (ie lack of bias) and precision have not yet been established.  Certified Reference Materials – Rock Labs and CDN CRMs have been used throughout the project including, low (~2 g/t Au), medium (~9 g/t Au) and high (~18g/t Au and ~40 g/t Au). Results are automatically checked on data import into the BEDROCK database to fall within 2 standard deviations of the expected value.   Samples with significant amounts of observed visible gold are also assayed by AuSCR21, a screen assay that analyses gold in both the milled pulp and in the residual oversize from pulverization. This has been done for holes CDH-075 and CDH-077.    Verification of sampling and assaying The verification of significant intersections by either independent or alternative company personnel.  The use of twinned holes.  Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.  Discuss any adjustment to assay data.  The verification of significant intersections by either independent or alternative company personnel has not been conducted. A re-assay program of pulp duplicates is currently in progress.  MTH has drilled one twin hole. Hole CDH-072, reported in the 15/6/2021 announcement, is a twin of holes EC-002 and UC-03. Results are comparable.  Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols are maintained in the company’s core facility.  Assay data have not been adjusted other than applying length weighted averages to reported intercepts.  Location of data points Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation.  Specification of the grid system used.  Quality and adequacy of topographic control.  Drill collar coordinates are currently located by handheld GPS. Precise survey of hole locations is planned. Downhole surveys of hole deviation are recorded using a Reflex Multishot tool for all holes.  A survey measurement is first collected at 15 meters downhole, and then every 50 meters until the end of the hole. Locations for holes have been surveyed with differential GPS to a sub 10 cm precision.   UTM/UPS WGS 84 zone 13 N  High quality topographic control from LiDAR imagery and orthophotos covers the entire project area.  Data spacing and distribution Data spacing for reporting of Exploration Results.  Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied.  Whether sample compositing has been applied.  Data spacing is appropriate for the reporting of Exploration Results.  The Resource estimation re-printed in this announcement was originally released on 17 Nov 2021  No sample compositing has been applied.  Orientation of data in relation to geological structure Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type.  If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.  Cut lines are marked on the core by the geologists to assure that the orientation of sampling achieves unbiased sampling of possible structures. This is reasonably well observed in the core and is appropriate to the deposit type.  The relationship between the drilling orientation and the orientation of key mineralised structures is not considered to have introduced a sampling bias.  Rock sawn channel samples are cut perpendicular to the observed vein orientation wherever possible  Sample security The measures taken to ensure sample security.  Samples are stored in a secure core storage facility until they are shipped off site by small aircraft and delivered directly to ALS Global sample preparation facility in Chihuahua, Mexico.  ALS airfreights the sample pulps to their assaying facility in North Vancouver, BC, Canada  Audits or reviews The results of any audits or reviews of sampling techniques and data.  A review with spot checks was conducted by AMC in conjunction with the resource estimate published 17 Nov 2021. Results were satisfactory to AMC.    Section 2 Reporting of Exploration Results 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.  Concessions at Copalquin    No. Concession Concession Title number Area (Ha) Location 1 LA SOLEDAD 52033 6 Tamazula, Durango, Mexico 2 EL COMETA 164869 36 Tamazula, Durango, Mexico 3 SAN MANUEL 165451 36 Tamazula, Durango, Mexico 4 COPALQUIN 178014 20 Tamazula, Durango, Mexico 5 EL SOL 236130 6,000 Tamazula, Durango and Badiraguato, Sinaloa, México 6 EL CORRAL 236131 907.3243 Tamazula, Durango and Badiraguato, Sinaloa, México   Exploration done by other parties Acknowledgment and appraisal of exploration by other parties.  Previous exploration by Bell Coast Capital Corp. and UC Resources was done in the late 1990’s and in 2005 – 2007. Work done by these companies is historic and non-JORC compliant. Mithril uses these historic data only as a general guide and will not incorporate work done by these companies in resource modelling.  Work done by the Mexican government and by IMMSA and will be used for modelling of historic mine workings which are now inaccessible (void model)   Geology Deposit type, geological setting and style of mineralisation.  Copalquin is a low sulfidation epithermal gold-silver deposit hosted in andesite. This deposit type is common in the Sierra Madre Occidental of Mexico and is characterized by quartz veins and stockworks surrounded by haloes of argillic (illite/smectite) alteration. Veins have formed as both low-angle semi-continuous lenses parallel to the contact between granodiorite and andesite and as tabular veins in high-angle normal faults. Vein and breccia thickness has been observed up to 30 meters wide with average widths on the order of 3 to 5 meters. The overall strike length of the semi-continuous mineralized zone from El Gallo to Refugio, Cometa, Los Pinos, Los Reyes, La Montura to Constancia and Santa Cruz is almost 7 kilometres. The southern area from south west of Apomal to San Manuel and to Las Brujas-El Peru provides additional exploration potential up to 6km.  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 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.    See Table 2 in the announcement. 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.  Potentially underground mineable intercepts are calculated as length weighted averages of material greater than or equal to 1 g/t AuEQ_70 allowing up to 2m of internal dilution.  Potentially open-pit mineable intercepts are calculated as length weighted averages of material greater than or equal to 0.25 g/t AuEQ_70 allowing for up to 2m of internal dilution.  No upper cut-off is applied to reporting intercepts.  Length weighted averaging is used to report intercepts. The example of CDH-002 is shown. The line of zero assays is a standard which was removed from reporting.  Au Raw silver raw Length (m) Au *length silver *length           7.51 678 0.5 3.755 339           11.85 425 0.55 6.5175 233.75           0 0 0 0 0           0.306 16 1 0.306 16           0.364 31.7 1 0.364 31.7           3.15 241 0.5 1.575 120.5           10.7 709 0.5 5.35 354.5           15.6 773 0.5 7.8 386.5                     From To Length Au gpt silver gpt     4.55 25.667 1481.9 91.95 96.5 4.55 5.64 325.7   In determining the gold equivalent (AuEq.) grade for reporting, a gold:silver price ratio of 70:1 was determined, using the formula: AuEq grade = Au grade + ((silver grade/70) x (silver recovery/Au recovery)). The metal prices used to determine the 70:1 ratio are the cumulative average prices for 2021: gold USD1,798.34 and silver: USD25.32 (actual is 71:1) from kitco.com  At this early stage, the metallurgical recoveries are assumed to be equal (93%), Subsequent preliminary metallurgical test work produced recoveries of 91% for silver and 96% for gold (ASX Announcement 25 February 2022).  For Rock Saw Channel Sampling and soil sampling in the Copalquin District, silver equivalent (AgEq) is determined using the formula: AgEq grade = silver grade + ((Au grade x 70) x (Au recovery/silver recovery)). The metal prices used to determine the 70:1 ratio are the cumulative average prices for 2021: gold USD1,798.34 and silver: USD25.32 (actual is 71:1) fromkitco.com   At this early stage, the metallurgical recoveries for Au and silver are assumed to be equal (93%) in the absence of metallurgical test work for Targets 2, 3, 4 and 5 material. In the Company’s opinion there is reasonable potential for both gold and silver to be extracted and sold.  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’).  True widths at Refugio between sections 120 and 1,000 vary according to the hole’s dip. Holes drilled at -50 degrees may be considered to have intercept lengths equal to true-widths, Holes drilled at -70 degrees had true widths approximately 92% of the reported intercept lengths and holes drilled at -90 degrees had true widths of 77% of the reported intercept lengths.   True widths at La Soledad are not fully understood and downhole intercepts to date, are reported.  At Las Brujas in Target 2, true widths are not yet known since we are still in the early stages of target definition.  Rock sawn channel samples are cut perpendicular to the observed vein orientation wherever possible  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.  See figures in 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.  All exploration results are reported for intercepts greater than or equal to 0.1 g/t gold equivalent (gold plus silver at 70:1 price ratio for gold:silver).  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.  No additional exploration data are substantive at this time.  Metallurgical test work on drill core composite made of crushed drill core from the El Refugio drill hole samples has been conducted.  The samples used for the test work are representative of the material that makes up the majority of the Maiden Resource Estimate for El Refugio release on 17th November 2021.  The test work was conducted by SGS laboratory Mexico using standard reagents and test equipment.  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.  The Company drilled 148 diamond core holes from July 2020 to July 2022 for 32,712 m.  The Company has stated its target to drill up to 45,000m from July 2025 until the second half of 2026  Diagrams are included in the announcements and presentations showing the drill target areas within the Copalquin District    1  See ‘About Copalquin Gold Silver Project’ section for JORC MRE details, AuEq (gold equivalent) and AgEq.
