Mithril to Acquire the La Dura Gold-Silver Property Adjacent to its Flagship Copalquin Property, Durango State, Mexico

About this update from Mithril Silver And Gold Limited

Melbourne, Australia , Vancouver, Canada - Mithril Silver and Gold Limited (' Mithril ' or the 'Company') (TSXV: MSG) (ASX: MTH) (OTCQB: MTIRF) is pleased to announce the execution of a Purchase Option to acquire the La Dura gold-silver property close to Mithril's flagship and district scale Copalquin property, both in Durango State, Mexico . The La Dura property consists of 5 contiguous mining concessions for a total area of 2,052 hectares, located less than 5 km from the town of El Durazno and less than 20 km from the Company's flagship Copalquin District property The La Dura property hosts several historic mines and workings with the most notable being the 4 level La Dura gold-silver mine with a 60 tonne per day processing facility The property has a large historic database of mining records and data from various sampling campaigns from 1990's to 2018. The mine last operated in 2013 The Company has an exclusive option to purchase 100% interest in the concessions at any time over 4 years by paying US$4 million to the vendor1 The Company will maintain the La Dura mining concessions in good standing and has committed to complete LiDAR and aerial magnetic surveys over the property in the first year and a minimum spend of US$200,000 on exploration work in the second year. The LiDAR survey is scheduled to be flown over the property this month followed by the aerial magnetic survey in early 2026. There are no further exploration expenditure commitments The acquisition of the La Dura property expands our land holding close to our flagship Copalquin District property, where drilling is progressing at Targets 1 and 5, with Target 3 drilling scheduled to commence in January 2026 . The first half of 2026 will be a pivotal period in the rapid advancement of the Copalquin District as we progress target expansion drilling and continue our geologic development of the feeder system responsible for the widespread gold and silver mineralisation across this large district. 'The historic La Dura mine was a notable past producer, and the local geology provides potential to host gold and silver mineralisation across the 20 km2 mining concession area', said John Skeet , Managing Director & CEO. ' La Dura lies within the same geologic locality as our flagship Copalquin property and is only 5 kilometres from our existing support office in the town of El Durazno . The upcoming LiDAR and aerial magnetic surveys will provide an initial assessment of the prospectivity across the 20 km2 concession area ahead of detailed mapping, sampling and future drill testing. Mithril has a strong foundation of knowledge at La Dura , with management having completed exploration work on the property in 2017-2018. The team's proven technical strengths and discovery experience at Copalquin position the Company well to unlock value at La Dura .' About the La Dura Project La Dura consists of 5 contiguous mining concessions with a total area of 2,052 hectares and located in Durango State, Mexico , 5 km from the town of El Durazno and 20 km from Mithril's flagship Copalquin property. The property hosts a significant Au-Ag sheeted to stockwork vein system associated with NW striking faults in Tertiary rhyolite. Mineralization occurs on surface along 650 metres of strike and has been mined in the San Manuel shoot at the La Dura historic mine, to about 140 metres depth. Veins are characterised by low sulphide mineralisation with minimal to no alteration of the host rhyolite tuff. Historically, the veins have been exploited and explored solely on the progress of the underground workings and assaying. The project warrants property scale mapping, wide spaced soil sampling and channel sampling to develop targets for drill testing. LiDAR and aerial magnetic surveys are planned as precursors to a field programme. The veins at the various workings appear to be hosted by Upper Series volcanic rocks and may have significant depth potential should they extend into the lower series andesitic rocks at some greater depth. ABOUT THE COPALQUIN GOLD SILVER PROJECT The Copalquin mining district is located in Durango State, Mexico and covers an entire mining district of 70km2 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 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.
