BP Silver (TSX-V:BPAG) reports ‘high-grade’ silver-bismuth-antimony mineralisation from its phase two drilling program at the Cosuño Silver Project in Bolivia.
Drill hole CO-0013 intersected 314.3 grams per tonne silver (Ag), 2.62% bismuth (Bi) and 0.74% antimony (Sb) over 3m. The result is equivalent to 1,328.8g/t silver equivalent (AgEq), within a broader 7m interval grading 168.8g/t Ag, 1.2% Bi, and 0.35% Sb.
The company has completed 19 drill holes totalling 2,289.7m in the expanded phase two program. Results from 17 holes remain pending.
Director and Qualifying Person Stewart Redwood says the Pocañita Chica target continues to demonstrate ‘high-grade’ silver mineralisation within feeder structures.
“Hole CO-0013 intersected a 3m feeder structure grading 1,328g/t silver equivalent, comprising silver, bismuth, and antimony,” Redwood remarks.
“Within a lithocap system, feeder structures can act as conduits for mineralising hydrothermal fluids and may connect to broader vein systems at depth.”
The bismuth and antimony are classified as critical minerals by the US Government, the Canadian Government, and the European Union. The world’s only primary bismuth deposit, Tasna, sits 65km southeast of Cosuño.
CEO Tim Shearcroft says CO-0013 returned the ‘highest silver equivalent grade’ of the program to date. He adds that with 19 holes completed and several more remaining, the potential at Pocañita Chica and across the broader Cosuño system warrants further testing.
BP Silver has completed a high-resolution drone magnetic survey covering 37.5km2 and commenced an induced polarisation survey to identify additional mineralised structures across the hydrothermal system.
At least eight additional drill holes remain under the current program. Drilling continues to test and expand mineralised structures identified to date.
BP Silver is a Canadian mineral explorer focused on advancing a portfolio of silver and polymetallic assets in Bolivia.
