• Drilling Highlights for intercepts in three diamond drill holes at El Refugio:
    • 8.0m @ 5.32 g/t gold, 104.63 g/t silver from 289.3m (CDH-063) including 1.0m @ 29.9 g/t gold, 273 g/t silver from 289.85m
    • 4.82m @ 4.12 g/t gold, 107.13 g/t silver from 259.7m (CDH-062) including 1.6m @ 7.94 g/t gold,211.10 g/t silver from 260.7m Plus 2.1m 4.68 g/t gold, 22.38 g/t silver from 299.5m
    • 7.75m @ 0.95 g/t gold, 24.7 g/t silver from 272m (CDH-061) Plus 15.77m @ 1.44 g/t gold, 76.3 g/t silver from 291m
  • The above intercepts extend the high-grade mineralisation 80m down dip
  • Drilling has continued at El Refugio intercepting structures up to 180m further to the west and up to a further 75m down dip
  • El Refugio continues to grow as a large high-grade gold and silver target

Mithril Resources Ltd (ASX: MTH) (Mithril or the Company) is pleased to provide an update on the fully funded exploration activities at its Copalquin Gold Silver District, Mexico.

Mithril CEO and Managing Director, John Skeet, commented:

“These are excellent intercepts to have received for holes drilled in this part of the Refugio target. They show continuing high-grade gold and silver, multiple vein intercepts and increasing widths. Drill holes up to 180m west have also been completed and we are currently drilling deep, vertical holes intercepting the structures further down dip.

The size of El Refugio continues to increase with the advancing diamond core drill program. We look forward to providing a continuing flow of news over the coming weeks.”

Following the recent drill hole CDH-050 (4.17m @ 62.0 g/t gold and 445 g/t silver from 233.43m) at the El Refugio target, results for drill holes CDH-061 – 063 have been received. Multiple vein intercepts are reported for each hole and with greater widths, adding significantly to the resource potential of the El Refugio target. Drilling is continuing at El Refugio with five more drill holes awaiting assays. Drilling is planned to intercept the structure/veins further down dip. The full reportable intercepts for the three diamond HQ drill holes are given below.


  • 7.75m @ 0.95 g/t gold, 24.7 g/t silver from 272m, plus 0.95m @ 0.95 g/t gold, 10 g/t silver from 291m, plus 15.77m @ 1.44 g/t gold, 76.3 g/t silver from 291m.


  • 4.82m @ 4.12 g/t gold, 107.13 g/t silver from 259.7m, including 1.6m @ 7.94 g/t gold, 211.10 g/t silver from 260.7m, plus 2.1m @ 4.68 g/t gold, 22.38 g/t silver from 299.5m, plus 3.17m @ 0.48 g/t gold, 36.50 g/t silver from 303.85.


  • 1.09m @ 1.46 g/t gold, 37 g/t silver from 282.66m, plus 8.0m @ 5.32 g/t gold, 104.63 g/t silver from 289.3m, including 1.0m @ 29.9 g/t gold, 273 g/t silver from 289.85m, plus 0.64m @ 1.14 g/t gold, 44 g/t silver from 309.32m.

Further drill holes are planned for the La Soledad and El Indio targets just to the north of El Refugio, and across to the east at Los Pinos. Below in Figures 4 to 6 are three cross section through the El Refugio target where the drill holes in this announcement are shown.

Figure 4: Cross Section 440, veins have developed with depth. Drill hole CDH-069 (awaiting assays) has intercepted the veins/structure 60-80m further down dip.
Figure 5: Cross Section 480, veins have developed with depth. Further drilling to continue to intercept the structure/veins deeper.

Figure 6 Cross Section 520, veins have developed with depth. Further drilling to continue to intercept the structure/veins at deeper.


The drill plan focus is on deeper drilling at Refugio with target depths between 300 to 400 m down hole. The majority of the drilling for the current quarter will be directed at Refugio and Soledad where our understanding of the target geometry continues to improve and gives us a high confidence for further success. Approximately 500 m of drilling will be used to drill two scout holes on the Los Pinos ridge where preliminary mapping and detailed soil-sampling indicate a good target along the Refugio to Los Reyes trend.


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.
