Mithril Resources Ltd (ASX: MTH) (Mithril or the Company) is pleased to provide exploration results for its 100% optioned Copalquin Gold Silver Project in Mexico where a maiden 529koz gold equivalent^* high-grade gold-silver JORC resource has been defined at El Refugio-La Soledad ^*(see ASX announcement 17 November 2021)

Mithril CEO and Managing Director, John Skeet, commented:

“The very high-grade CDH-140 intercept is an excellent result adding significantly to the El Refugio resource confidence on this westerly ‘section 800’ where there is no previous drilling. Drill hole CDH-141 intercepted a wide zone of gold-silver mineralisation with several reportable and high-grade intercepts, demonstrating the size and continuity of the El Refugio structure and its significance in the Copalquin District. Drilling at the eastern end of El Refugio has been completed with good observations in drill core and awaiting assays. Study work is producing development opportunities for the El Refugio resource to progress over the coming months.”

El Refugio Drilling May-June 2022

Drilling recommenced at El Refugio in May 2022 with a program of six deep holes, three drilled from a location slightly oblique to the main structure, in order to reduce the length of the drill holes to reach the targeted depth. Assays have been received for all drill holes. The program successfully achieved the objective of locating the main structure and confirming high-grade gold and silver on the western side of the El Refugio resource area while providing additional information for the location of the upwelling feeder zone. The previously reported intercept in hole CDH- 137 of 5.67m @ 4.37 g/t gold, 174g/t silver from 331.33m, (CDH-137), including 1.67m @ 9.64 g/t gold, 399 g/t silver from 331.33 plus 1.00m @ 1.68 g/t gold, 67.2 g/t silver from 367.0m and 1.00m @ 1.27 g/t gold, 46.1 g/t silver from 370.0m filled a gap down dip on section 560 and drill hole CDH-136 confirms the downdip extension with some further high-grade gold and silver mineralisation and multiple intercepts.

The first drill holes on section 800 are reported with exceptional high-grade gold and silver intercepts in this western side of the El Refugio resource area with 5.83m @ 15.7 g/t gold, 474 g/t silver from 91.77m, (CDH-140), including

1.81m @ 45.5 g/t gold, 1,387 g/t silver from 93.77m down dip of hole CDH-139 (Figure 3). This supports the high- grade previously intercepted 40m west by drill hole CDH-094 with 18.87m @ 9.67g/t gold, 279g/t silver.

El Refugio Drilling June-July 2022

A drill programme has recently been completed on the eastern side of El Refugio targeting deep and near to where the main El Refugio upwelling zone is projected.

Core from the most recent holes have the first observed occurrences of platy quartz after calcite, a texture indicative of boiling and gold deposition. Late amethyst is also observed filling what was open space at the time of mineralization. This texture is indicative of boiling. Visible silver minerals are commonly observed in the mineralized veins. All drill core samples have been dispatched for assay.

The above figure shows an oblique view of the La Soledad-El Refugio vein and block models with traces of drill holes to date. Recent drill logs and results show significant depth potential of this major system and also indicate the general location of the El Refugio upwelling feeder zone and this is consistent with the epithermal gold-silver model shown in the figure below.

Scoping Study Work

Work is progressing to assess the first stage development options to optimally exploit the high-grade El Refugio resource. Recent drilling has been spaced across the strike of the mineralized zone to infill strategic areas. There are options to reduce the mine development meterage and to take advantage of topography and high-grade zones within the El Cometa-El Refugio resource on the eastern side of the deposit to potentially produce attractive development economics including low initial capital requirements and short payback period.

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 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).

• 2,416,000 tonnes @ 4.80 g/t gold, 141 g/t silver for 373,000 oz gold plus 10,953,000 oz silver (Total 529,000 oz AuEq*) using a cut-off grade of 2.0 g/t AuEq*
• 28.6% of the resource tonnage is classified as indicated

*AuEq. = gold equivalent calculated using and gold:silver price ratio of 70:1. That is, 70 g/t silver = 1 g/t gold. 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

Mining study and metallurgical test work supports the development of the El Refugio-La Soledad resource with conventional 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 in 2022 to demonstrate its multi-million ounce gold and silver potential.

Mithril Resources is earning 100% interest in the Copalquin District mining concessions via a purchase option agreement detailed in ASX announcement dated 25 November 2019.

District South Section

The Las Brujas-El Peru target is drill ready following positive results from the rock chip sampling program from within the historic mine working and the soils sampling program that revealed a good gold and silver anomaly. The historic mine workings at Las Brujas and at El Peru are connected by a 500m long surface trace of quartz vein.

Mapping and rock chip sampling of a north-south oriented structure at El Guamuchilito has been completed. Aerial drone surveying will continue until the end of the dry season usually around mid-late June.
