USGS releases first study to assess global earthquake risk to mineral supplies
Earthquakes have the potential to substantially affect mining operations, leading to supply chain disruptions that adversely affect the global economy.
Talisker Resources (TSX: TSK) has reported very long mineralized intervals from drilling at its 100%-owned Bralorne gold project, where it is preparing an initial resource estimate due out in 2022.
In the Pioneer block, Hole 2021-040 extended mineralization 140 metres down plunge and intersected 114.2 metres grading 1.02 g/t gold. This represents part of a longer, 200-metre intersection grading 0.73 g/t gold.
This is part of the bulk-tonnage mineralization discovered in June at Pioneer, located 2 km southeast of Bralorne township.
Above the bulk-tonnage mineralization, recent drilling also intersected the Pioneer main vein, returning 6.4 metres of 7.46 g/t gold.
The Bralorne complex – consisting of the Bralorne, Pioneer and King mines – was one of the highest grade, longest producing gold mines in British Columbia. A total of 4.2 million oz. was produced from an average recovered grade of 17.7 g/t before mining was suspended in 1971.
Only 30 of the 63 known veins were mined, and 29 of them only to a depth of 900 metres. Only the 77T vein went deeper – to 1,900 metres. It remains open at depth as do all the other veins.
Talisker acquired the Bralorne project in November 2019 from Avino Silver and Gold for a cash payment of C$8.7 million plus shares and warrants. Bralorne is fully permitted, including the tailings storage facility.
