June 3, 2025

  • High-Grade Channel Sampling Highlights Compelling New Drill Target -

Melbourne, Australia and Vancouver, Canada Mithril Silver and Gold Limited ("Mithril ' or the "Company") (TSXV: MSG) (ASX: MTH) is pleased to provide high-grade channel sample results for a newly developing drill target (Target 5) at Mithril's district scale Copalquin property, Durango State, Mexico.

Highlights

  • Mithril's ongoing mapping and sampling program continues to uncover high -grade gold-silver drill targets across the expansive 70 km² Copalquin District in Mexico.
  • Recent work at Target 5 has outlined multiple northwest-trending parallel veins up to 500 metres in length within a 1.6 km wide corridor, located just 1.5 km southwest of the existing Target 1 resource area.
  • Notably, sampling at this lower elevation (650 -900 m) has returned grades exceeding 1% copper, lead, and zinc. Mineralisation has now been found for over 1,000 metres of vertical relief between Target 2 and Target 5. The styles of mineralisation and associated host rocks support the model of a district wide epithermal system potentially centred along a 5km eastwest trend of rhyolite flow domes.
  • First-pass drilling at Targets 5 and 3 is scheduled for next quarter , following the completion of Target 1 resource update drilling and the district-scale geological model refinement.

Highlight channel sample results from surface and underground workings within Target 5:

  • 0.7 m @ 4.64 g/t gold, 732 g/t silver (226229; Mina Apomal)
  • 0.8 m @ 2.84 g/t gold, 777 g/t silver (527107; Mina Apomal)
  • 0.5 m @ 5.36 g/t gold, 706 g/t silver (527143; Apomal Norte)
  • 0.8 m @ 2.58 g/t gold, 716 g/t silver (798719; Dulces Nombres)

Samples with high base metal values:

  • 1.0 m @ 1.48 g/t gold, 236 g/t silver, 0.17% copper, 1.73 % lead, 0.06% zinc (798776; Veta Azul)
  • 1.0 m @ 0.04 g/t gold, 8 g/t silver, 0.03% copper, 0.09 % lead 1.28 % zinc (79770; Veta Azul)
  • 1.0 m @ 0.07 g/t gold, 41 g/t silver, 1.59 % copper, 19 ppm lead, 61 ppm zinc (226223; Apomal)
  • 0.85 m @ 0.06 g/t gold, 145 g/t silver, 0.1% copper, 1.14 % lead , 0.05% zinc (527169; Duraznito)

'The high -grade channel sampling results at Target 5 are another strong endorsement of the Copalquin District's potential to host multiple, high -grade gold-silver deposits, ' said John Skeet, MD and CEO of Mithril Silver and Gold. ' The wide vein corridor at Target 5, high grades, and presence of significant base metals at lower elevations underscore the robust vertical extent of this epithermal system. Importantly, these results confirm that our district-scale exploration strategy is delivering, with Target

ADVISORS

5 now emerging as a compelling new drill target. We look forward to commencing the first-ever drilling at this area in the upcoming quarter, alongside continued work to update the resource at Target 1 and further define the broader mineralised system across the Copalquin District .'

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) 1 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 ( see ASX announcement 01 March 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.

Copalquin District Exploration Progress Update

Surficial and underground channel sampling at the Target 5 Area (El Apomal, El Duraznito, Veta Azul, Dulces Nombres) has returned excellent results, with several channel samples intersecting very highgrade silver and high-grade gold within a broad, outcropping vein system, which extends 1.6 km west of the Dulces Nombres to El Apomal Mine ( Figure 4 ).

Full sample results are given in Table 2

Significant gold and silver target 5 channel sampling highlights include:

Dulces Nombres Mine area: 1.0 m@ 0.141 g/t Au, 841 g/t Ag (798709; underground) 0.8 m @ 2.58 g/t Au, 716 g/t Ag (798719; underground) El Apomal Mine area: 0.7 m @ 4.64 g/t Au, 732 g/t Ag (226229; underground) 0.8 m @ 3.14 g/t Au, 333 g/t Ag (226241; underground) 0.9 m @ 5.2 g/t Au, 297 g/t Ag (226244; underground) 0.6 m @ 1.25 g/t Au, 381 g/t Ag (527103; underground) 0.8 m @ 2.84 g/t Au, 777 g/t Ag (527107; underground) 1.0 m @ 2.47 g/t Au, 252 g/t Ag (527141; surface)

High-Potential Discovery at Target 5 -El Apomal: Target 5 development started with the dewatering, mapping and sampling of the historic El Apomal Mine ( Figure 3 ). The mine, a 130-metre underground adit, is dominated by a mineralized quartz vein, up to 1.5 m wide (The Apomal vein). The southeast trending Apomal vein can be traced over 500 metres and remains open to the northwest and southeast. Several parallel vein sets have been mapped and sampled up to 300 m to the southwest of the Apomal Mine ( Figure 3 ; Assays pending).

Anomalous silver values (up to 196 g/t Ag ; Table 3) have been reported at the El Duraznito Mine which is located more than 300 m to the northeast of the Apomal mine ( Figure 4, 5 ; Table 2 ).

The Veta Azul and Dulces Nombres Mines are located over 900 m northeast of the El Duraznito Mine and have returned high-grade silver values (up to 841 g/t Ag; Figure 4; Table 2 ). The veins in these mines appear to have a similar orientation to the veins observed underground and on surface in the El Apomal Mine area.

Moderate-grade Au and Ag mineralized quartz veins were intersected in two holes (CDH152 -5.66m @ 2.58 g/t gold, 230 g/t silver from 18.5m including 1.98m @ 4.59 g/t gold, 520 g/t silver from 18.5m and CDH-154 - 2.90m @ 1.86 g/t gold, 240 g/t silver from 75.1m) drilled at the historic Copalquin Mine which is located approximately 2.5 km east of El Apomal Mine . The veins at Copalquin are interpreted to be part of the wide vein system observed at Target 5.

Target 5 veins mapped to date, are primarily hosted in granodiorite and are situated at a lower elevation in the system at 650 -900 m compared with the mineralised zones at Target 1 (900 -1,150 m) and Target 2 (1,500 - 1,700 m). Mineralised parallel vein sets have now been mapped and sampled for over 1,000 metres of vertical relief between Target 2 and Target 5 across a width of approximately 5 km, a further indication of the Copalquin District to potentially host a large, multi-target mineralized system.

The styles of mineralisation and associated host rocks found at various elevations conform to the model of a district wide low sulphidation epithermal system potentially centred along a 5km eastwest trend of rhyolite flow domes.

Continued mapping and sampling is underway to the south and southeast of the El Apomal Mine where several outcropping veins have been identified. An exploration road is advancing to the Target 5 area to provide access for drill pads.

Further targets for mapping and sampling include the areas to the immediate south of Target 5 towards the historic mines Tasolera 1 and 2 (~1 km from Apomal) and to the southeast towards the historic mine Guamuchilito (~1.7 km from Apomal).

ABOUT THE COPALQUIN GOLD SILVER PROJECT

The Copalquin mining district is located in Durango State, Mexico and covers an entire mining district of 70km 2 containing several dozen historic gold and silver mines and workings, ten of which had notable production. The district is within the Sierra Madre Gold Silver Trend which extends north-south along the western side of Mexico and hosts many world-class gold and silver deposits.

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+

  • 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. At this early stage, the metallurgical recoveries were assumed to be equal. 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.

The Company confirms that it is not aware of any new information or data that materially affects the information included in the original market announcement and that all material assumptions and technical parameters underpinning the estimates in the relevant market announcement continue to apply and have not materially changed. The company confirms that the form and context in which the Competent Person's findings are presented have not been materially modified from the original market announcement.

For Target 5 area where silver equivalent (AgEq) has been used in the maps, AgEq is determined using the formula: AgEq grade = Ag grade + ((Au grade x 70) x (Au recovery/Ag 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 for Au and Ag are assumed to be equal in the absence of metallurgical test work for Target 5 material. In the Company's opinion there is reasonable potential for both gold and silver to be extracted and sold.

Mining study and metallurgical test work supports the development of the El Refugio-La Soledad resource with conventional underground mining methods indicated as being appropriate and with high gold-silver recovery to produce metal on-site with conventional processing.

Mithril is currently exploring in the Copalquin District to expand the resource footprint, demonstrating its multi-million-ounce gold and silver potential. Mithril has an exclusive option to purchase 100% interest in the Copalquin mining concessions by paying US$10M on or any time before 7 August 2028.

JORC Code, 2012 Edition -Table 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 msamples 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 mbut may vary between 0.5 mto 1.5m 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
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 drillingHQ size core to depths of 350-400m (depending on ground conditions), reducing toNQ 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. • 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.
Criteria JORC Code explanation Commentary
• 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. • 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
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 ½of 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 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. • 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 AgOG63 and AgGRAV21. 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
Criteria JORC Code explanation Commentary
• 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 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. • Soil sampling is also subject to a program of standards and blanks using the X-ray florescence (XRF) analyser. Results are acceptable. Samples were analysed using three wavelengths 50Kv, 40 Kv and 15 Kv for times of 120 seconds, 30 seconds and 30 seconds respectively. • 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 CDH-001 through CDH-048 and CDH-051 through CDH-148 have been surveyed with differential GPS to a sub 10 cm precision. Hole CDH-005 was not surveyed • UTM/UPS WGS 84 zone 13N • High quality topographic control from LiDAR imagery and orthophotos covers the entire project area.

Resource and Ore Reserve estimation procedure(s) and classifications applied. • Whether 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.
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.

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 is almost 6 kilometres. The southern area from Apomal to San Manuel and to Las Brujas-El Peru provides additional exploration potential up to 5km.
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. • No new drilling reported in this announcement

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 • 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 17 th November 2021. • The test work was conducted by SGS laboratory Mexico using standard reagents and test equipment.
