Mithril Silver and Gold Limited ("Mithril” or the "Company") (TSXV: MSG) (ASX: MTH) is pleased to provide high-grade maiden drill results for a new drill discovery at the Target 2 area in Mithril’s Copalquin silver and gold district property, Durango State, Mexico (Figure 1).
Exploration Progress Update
Drilling at Target 2 (Las Brujas) has returned excellent results, with shallow holes over a 200-metre strike length intersecting very high-grade gold and silver within a broad, near-surface structure. Hole T2DH25-006 returned 11.5m @ 8.61 g/t gold, 57.6 g/t silver from 44.5m, including 3.85m @ 25.33 g/t gold, 128 g/t silver from 46.65m including 0.85m @ 109.5 g/t gold, 325 g/t silver from 46.65m. Follow-up drilling ~80 metres down dip is planned for the next phase.
Momentum Building Across the Copalquin District – Multiple Targets Advancing (Figure 2)
- Exciting Progress at El Peru (Target 2 Extension): The first phase of drilling at El Peru, 400 m east of Las Brujas, has been completed. Multiple shallow drillholes have shown further extension of the mineralized footprint of this emerging high-grade zone (samples dispatched).
- Eastern District Activity Ramps Up: A second exploration camp has been established to support aggressive mapping and target generation at Targets 2 and 3, highlighting our commitment to unlocking the eastern potential of the district.
- High-Potential for additional Discovery at Target 5 – El Apomal: A new target has been defined at the historic El Apomal workings. A 130-metre underground adit has been dewatered, mapped, and sampled (assays pending), and a surface vein has been traced over 300 metres — a compelling new drill target developing.
- District-Scale Potential Confirmed: Over 1,000 metres of vertical relief between Target 2 and Target 5 across 5 km demonstrates the immense scale and structural complexity of the Copalquin district, underscoring its potential to host a large, multi-target mineralized system.
- Resource Expansion Underway at Target 1: Deep drilling at the El Refugio structure continues to intercept the targeted zone, with samples dispatched for assay. Drilling success here will directly contribute to an upcoming Target 1 resource update.
“We’re advancing on multiple fronts across the Copalquin district, with strong drill results at Las Brujas, exciting new potential at El Apomal, and ongoing success at our flagship Target 1 resource area,” said John Skeet, CEO and Managing Director. “The scale of this system is becoming increasingly evident, with multiple mineralized zones across the district. With drilling, mapping, and sampling all in full swing, we’re well positioned to continue building momentum and unlock significant value through discovery and resource growth.”
COPALQUIN GOLD-SILVER DISTRICT, DURANGO STATE, MEXICO
Figure 1 Copalquin District location map, locations of mining and exploration activity and local infrastructure
With 100 historic underground gold-silver mines and workings plus 198 surface workings/pits throughout 70km2 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.

Extensions and New Zones of High Grade Tin at Bygoo North
HIGHLIGHTS
- Scale of Bygoo Tin Project continues to grow with the discovery of new zones of tin mineralisation during the Company’s second RC drilling campaign
- Very broad zone of tin mineralisation at the Stewart’s Lode extended along strike with:
- 118m @ 0.32% Sn from 44m in BRC015 (unconstrained internal dilution); including
- 29m @ 0.53% Sn from 44m, including 8m @ 1.17% Sn from 45m
- 12m @ 0.45% Sn from 116m; and
- 28m @ 0.52% Sn from 146m
- Caspin’s maiden drilling at the Smith’s Lode returns further high-grade tin with:
- 16m @ 0.68% Sn from 49m (BRC013); including
- 5m @ 1.73% Sn & 1.45% Cu from 53m;
- Drilling identifies a further new zone of mineralisation named ‘Radius’, between Dumbrell’s and Smith’s, with:
- 16m @ 0.48% Sn from 124m (BRC016); including
- 2m @ 2.05% Sn & 0.37% Cu from 128m
- Wide zones and high-grade tin mineralisation now drilled over +1,000m of granite contact zone with large gaps in drilling and open along strike.
- High resolution aerial magnetic survey covering ~800km2 to commence shortly
Caspin’s Managing Director, Mr Greg Miles, commented “These results are an exciting epilogue to our maiden drilling program at the Bygoo Project. We are delighted with intersecting 16m @ 0.68% Sn in our first drill hole at Smith’s, including a high-grade zone of 5m @ 1.73% Sn, coupled with 1.45% Cu, the highest-grade copper result by Caspin to date. Another 100m-plus intersection of tin mineralisation at Stewart’s also confirms continuity of ‘bulk’ mineralisation, at very shallow depths. And finally, a new zone of tin mineralisation at ‘Radius’ result demonstrates verifies Caspin’s geological model and growing understanding of key controls to tin mineralisation.
“Most importantly, we now recognise the tin mineralisation potential over greater than 1,000m of shallow granite contact strike at Bygoo North. Drilling is quickly demonstrating that Bygoo North has excellent potential to grow into a tin project with substantial scale. Drilling will continue to target new zones of tin mineralisation and extensions of known areas of shallow tin mineralisation along strike.”
Since acquiring the project, the Company has invested considerable time to understand the geology and controls on mineralisation at Bygoo North. Using the previous exploration data as a base and steadily importing other legacy data such as drilling from the 1970s, the Company is developing a new geological model for the prospect. The Ardlethan Granite contact can now be traced over 1,000m at the prospect, with greisen-style mineralisation developed variably along its entirety (Figure 1).
Figure 1. Location plan of mineralisation and relationship to granite contact at Bygoo North, with significant intercepts. The prospective granite horizon represents the potential for greisen mineralisation on the granite contact to approximately 100m below surface.
These latest results provide further evidence that mineralisation is constrained only by drilling. There are obvious additional drill targets for further exploration. A planned high-resolution aerial magnetic survey, commencing in the following weeks, will further assist refinement of the geological model and hence the targeting process, particularly the several kilometres of untested granite contact to the north and south.

Lake Hope HPA Pre-Feasibility Study and Maiden Ore Reserve
- Very strong economic metrics and low-cost production: NPV10 A$1.165 billion (with no by-product revenue)
- Capex A$259 million
Opex US$5,860 per tonne excluding by-product credit - Potential Opex of <US$4,500 with by-product credit
- Maiden Probable and Proved Ore Reserve of: 1.7 Mt at 26% Al2O3 for 450,000 tonnes of contained Al2O3.
- Election to proceed to an 80% interest in Playa One Pty Ltd providing Impact with 80% ownership in the Lake Hope resource and intellectual property.
- Definitive Feasibility Study to commence with construction of pilot plant and investigation into the integration of Lake Hope with the HiPurA process.
The PFS highlights the project's exceptionally strong economics and outlines a pathway for Lake Hope to become a global supplier of low-cost, low-carbon HPA, benefiting both the local Ngadju Aboriginal Native title holders and the broader community. The robust economics stem from the unique characteristics of the Lake Hope deposit, which facilitate cost-effective mining and processing.
The PFS confirms that, to the best of Impact's knowledge based on published data, the Lake Hope project could be among the lowest-cost producers of HPA globally, potentially by a significant margin of at least 30%.
Given these strong fundamentals, Impact will issue 120 million shares, escrowed for 12 months, to exercise its option to acquire an 80% interest in Playa One Pty Ltd, which owns the Lake Hope assets and intellectual property, including two patents for metallurgical processes (ASX Release March 21st 2023).
Work will now commence on a Definitive Feasibility Study (DFS), which will include the construction of a pilot plant to produce HPA samples at scale for discussions on offtake agreements. The pilot plant project, currently underway, will be part-funded by the recent federal government grant awarded to Impact Minerals in collaboration with CPC Engineering and Edith Cowan University (ASX Release October 22nd 2024).
In addition, as part of these studies, Impact will focus on the potential integration of the Lake Hope ore and its associated metallurgical processes with the assets and intellectual property related to the HiPurA process, which were recently acquired through Impact’s 50% share in Alluminous Pty Ltd (ASX Release April 23rd 2025).
As the acquisition occurred near the end of the PFS, the study only pertains to Lake Hope as a stand-alone project and does not consider integration with HiPurA. Impact believes the HiPurA acquisition will accelerate the Company’s entry into the HPA market by several years, potentially enhancing the economics of the combined projects.
Lake Hope PFS Summary
Impact Minerals’ Managing Director, Dr Mike Jones, said, “The Lake Hope PFS clearly demonstrates that Impact Minerals is now on the cusp of delivering a significant, low-cost and highly scalable HPA project. In just over two short years since acquiring the rights to the project, we have proven that Lake Hope’s unique natural feedstock, combined with a straight-forward flowsheet, offers one of the most capital-efficient and environmentally responsible pathways to high-purity alumina production globally. The Project’s strong margins, minimal carbon footprint, and ability to deliver 4N product without critical reagents or complex processing provides us with a clear competitive advantage as the HPA market enters a phase of rapid growth.”
“Importantly, the PFS positions Lake Hope to potentially be the upstream foundation of our vertically integrated HPA business. Through our recent acquisition of a 50% interest in Alluminous Pty Ltd and the HiPurA® downstream processing technology we are now accelerating plans to seamlessly integrate Lake Hope feedstock with HiPurA’s potentially modular HPA production capacity. This unique model offers Impact the flexibility to scale production in line with market demand and customer qualification, while minimising capital intensity and de-risking the path to early revenues.”
“With the PFS now complete, our next steps are clear: we will advance the detailed engineering required to bring Lake Hope into production, which will revolve around our exciting federal government co-funded membrane research project now underway in conjunction with Edith Cowan University and CPC Engineering. We believe very significant improvements to our flow sheet will emerge from that work. We will also progress approvals and initiate off-take discussions. At the same time, we will help fund and rapidly develop the HiPurA® modular production pathway to establish near-term capacity and position Impact as a differentiated, vertically integrated supplier of high-purity alumina to the global market. The opportunities in front of us are significant and today marks a major milestone in what is shaping up to be an exciting future for Impact Minerals and our shareholders.”
