Sierra Nevada Gold (ASX: SNX) has commenced RC drilling at the high-grade silver Endowment Mine within its Blackhawk Epithermal Project in Nevada, USA.
The compass is drilling up to 12 holes for approximately 1,500m at Blackhawk over the next two to three weeks.
Drilling will focus on testing remnant high-grade ore positions, vein extensions, near surface mineralised breccias and chargeability targets generated by Induced Polarisation (IP) surveys/
The company has identified a large and high-grade intermediate sulphidation epithermal (ISE) Ag-Au-Pb-Zn vein field, related to a large porphyry system located immediately to the south of the Epithermal Project. Partially coincident with the Blackhawk porphyry system, the Blackhawk ISE vein system covers about five sq. km and is open under cover both to the north and northeast, with 22.5-line km of veins identified to date.
Recent and ongoing mapping and sampling by Sierra Nevada has identified further veins within ISE vein field.
“We are excited to have the drill program underway at Blackhawk to test the most prospective silver targets and given we have spent considerable time and planning in refining these targets, we’re very keen to see what it returns," Executive Chairman, Peter Moore, said.
"Previous drilling at the Endowment Mine has delivered high-grade results up to 1270g/t silver. With more than 20km of veins identified to date, we are working to test the most prospective areas first.”
