Mithril Resources Ltd (ASX: MTH) (Mithril or the Company) is pleased to release further exploration and drilling results at its Copalquin Gold Silver District, Mexico.

Mithril CEO and Managing Director, John Skeet, commented:

“The intercept in drill hole CDH-094 demonstrates the Refugio structure continuity west to the next ridge with thick high-grade gold-silver mineralisation. Drilling is continuing at El Refugio with hole CDH-096, our deepest hole to date (504m), with a broad quartz breccia zone in the last 50m of the hole. The intercepts are in line with the geologic model and El Refugio continues to expand at depth and west, outside the first resource area within our 70 square kilometre Copalquin Mining District.”

Grade thickness as shown is the sum of all intercepts shown for each hole, pierce points are the midpoint of the main intercept. Metal equivalent grades calculated using 70 g/t Ag = 1 g/t Au, based on gold price of USD1,610 per ounce and silver price of USD23 per ounce.

Assays for drill holes CDH-085 to CDH-090 plus CDH-094 have been received. Assay turn-around times from the ALS Vancouver laboratory have increased. Samples from CDH-094 were sent to another ALS laboratory allowing those results to be available in a shorter time. Holes CDH-085 to CDH-090 were drilled to complete the database for the maiden mineral resource estimate (MRE). Drilling has continued at El Refugio, with a series of deeper holes and holes further to the west. On the western side of the centre ridge, the structure is stronger depth and has continued across the valley to the next ridge with the excellent high-grade intercept from drill hole CDH-094 (18.67m @ 9.64 g/t gold, 278.8 g/t silver from 144.0m including 9.30m @ 17.9 g/t gold, 482.2 g/t silver from 148.89m, plus 3.00m @ 1.88 g/t gold, 61.7 g/t silver from 137m).

CDH-096 is a deep hole drilled in the central part of El Refugio, to the maximum depth with the drill pipe on site. The hole stopped in quartz breccia with several quartz breccia zones within the last 50 metres of the 504 metre drill hole.

A drill hole to follow up the high-grade gold-silver intercept in CDH-072 (6.80m @ 74.0 g/t gold, 840.5 g/t silver from 35.2m) is scheduled to further test this structure on the eastern side of El Refugio at El Cometa. The drill will then be moved by helicopter to follow up the intercept in CDH-094 (see Figure 3 below).

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.

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.

Preliminary Concept for Mine Access – El Refugio

Deep high-grade intercepts such as in holes CDH-061, CDH-071 and CDH-077 bring mineralisation closer to potential access from a site with favourable logistics, taking advantage of the local topography. The CDH-077 ‘bonanza zone’ can be reached by an exploration drift (adit) of approximately 750 metres long. Such a drift would allow access for the close-spaced sampling that will be necessary to bring the bonanza grade zone into higher confidence resource categories.
