    Mithril drill program delivers 74 g/t gold over 6.8m at Copalquin District, Mexico

    Mithril Resources Ltd (ASX: MTH) has reported “bonanza high-grade” results including 6.8m @ 74 g/t gold, 841 g/t silver from 35.2m from the shallow drilling at El Cometa, within its Copalquin Gold Silver District, Mexico.

    MTH said that the drilling has resulted in continued expansion of the El Refugio structure to 650m long and 300m down dip. Other significant results included 4.61m @ 1.87 g/t gold, 89.3 g/t silver from 155.84m; 7.60m @ 2.34 g/t gold, 143.6 g/t silver from 253.25m; 6.00m @ 1.41 g/t gold, 66 g/t silver from 240m; and 1.05m @ 2.36 g/t gold, 95.3 g/t silver from 186m.

    MTH said that the drilling has resulted in continued expansion of the El Refugio structure to 650m long and 300m down dip

    The company said that drilling continues along the El Refugio structure with deep holes CDH-075 – 076 intercepting multiple veins, whose assays are awaited.

    MTH said that soil sampling has commenced to extend the El Refugio structure a further 1.3 km west.

    Cometa project

    The company’s Copalquin District mining concessions cover 70km2 and include dozens of historic mines and workings. The Cometa Project area includes the historic La Soledad and El Refugio multilevel mines that operated in the second half of the 19th century.

    Exploration and drilling programs

    The company had recently commenced exploration and drilling at its Copalquin Gold Silver District, Mexico.

    MTH said that assay results for four drill holes (CDH-068, CDH-069, CDH-070, and CDH-071) were received expanding the El Refugio structure, plus a hole (CDH-072) designed to twin historic drill hole UC-03, intercepting extreme high-grade gold and silver.

    High-grade results

    The company announced that bonanza high-grade results were reported from shallow drill hole CDH-072 completed at El Cometa, suggesting north-south trending structure, while the company’s deeper drilling to extend the eastern side of the El Refugio clavo showed excellent continuity intercepting multiple veins.

    CDH-072

    The company said that the drill hole CDH-072, twin of historic UC-03, was Mithril’s follow up test of the Cometa portion of the Refugio to Los Reyes structural zone.

    Standout intersections from CDH-072 included 6.8m @ 74 g/t gold, 841 g/t silver from 35.2m including 2.1m @ 235 g/t gold, 2,554 g/t silver from 37.9m.

    CDH-068

    The company said that the drill hole CDH-068 extends the main Refugio structure another 60 meters to the west. Important results included 4.61m @ 1.87 g/t gold, 89.3 g/t silver from 155.84m, plus 0.77m @ 4.00 g/t gold, 37.0 g/t silver from 176.41m, plus 0.90m @ 0.59 g/t gold, 38.0 g/t silver from 193.38m.

    CDH-069

    The company said that CDH-069 was a deeper hole on the same section as CDH-062. Significant results included 7.60m @ 2.34 g/t gold, 143.6 g/t silver from 253.25m plus 1.00m @ 2.64 g/t gold, 167.0 g/t silver from 266.35m.

    CDH-070, CDH-071

    The company said that the drill holes aggressively stepped down dip of hole CDH-053 on the eastern side of the El Refugio clavo have extended the veins deeper by 50 metres (CDH-070) and 100 metres (CDH-071).

    Important results from CDH-070 included 6.00m @ 1.41 g/t gold, 66 g/t silver from 240m including 0.50m @ 9.53 g/t gold, 613 g/t silver from 240m, plus 1.00m @ 4.94 g/t gold, 96.0 g/t silver from 235.87m, plus 1.80m @ 2.38 g/t gold, 53.1 g/t silver from 157.55m.

    Standout intersections from CDH-071 included 1.05m @ 2.36 g/t gold, 95.3 g/t silver from 186m, plus 0.50m @ 28.9 g/t gold, 471 g/t silver from 222.77m, plus 1.66m @ 2.41 g/t gold, 152.8 g/t silver from 235.87m.

    Drilling ongoing

    The company said that drilling continues along the El Refugio structure with deep holes CDH-075 – 076 intercepting multiple veins, whose assays are awaited.

    Soil sampling

    The company had announced soil sampling results (silver only) for the Refugio and part of Refugio West areas on March 24, 2021. After receipt of the gold analysis, the area was re-interpreted identifying low-level gold anomalies that correspond to the locations of mapped quartz-bearing structures.

    Mithril said that a follow-up soil sampling program over the Refugio West target is underway with 240 samples planned to be collected from five sample grids of 48 samples each. MTH said that successful results from this program may extend the target zone for drilling a full 1,300 meters west from the currently westernmost drill holes.

    What’s next?

    The company said that the drill will soon be relocated to La Soledad to deepen existing drill holes to intercept the Leon vein intercepted by CDH-014 and CDH-054 and which was also observed in CDH-001 and CDH-010. MTH said that subsequently the drill will target the intersection of the El Refugio and the La Soledad structures. This an important target determined by the vein models developed from the 3D modelling of the drill data.

    Management statements

    Mithril CEO and Managing Director, John Skeet, said: “With the extremely high-grade intercept in hole CDH-072 we have confirmed the bonanza grades El Cometa intercepted by the historic drilling (UC-03) and further developed the model for the complex El Cometa vein system. The model will guide future exploration in this structure which extends 2km east to Los Reyes.

    Our deeper drilling to extend the eastern side of the El Refugio clavo has shown excellent continuity intercepting multiple veins. Hole CDH-068 has confirmed further westerly extension of the El Refugio structure ahead of exploration work aimed at expanding the structure up to 1.3km west.

    El Refugio has already grown to 650m long and 300m down dip and with a very high-grade zone (clavo) within the mineralised structure. Recently completed deep (+400m) drill holes have continued to intercept the central portion of the clavo and we look forward to reporting these results.”
