Silver Bow Mining intersects 0.82 meters at 8.2% CuEq on Black Rock Copper Vein at Rainbow Block project in Montana
SBMT•Massive sulfide intercept at Rainbow Block
Silver Bow Mining reported a massive sulfide intercept at its Rainbow Block project in Butte, Montana, on the Black Rock Copper Vein.
Hole SBM26-09 cut 0.82 meters grading 8.20% CuEq, including 6.22% copper, 207.1 g/t silver, 0.27% zinc.
The intercept sits about 30 meters below an unmined copper-silver block shown in Anaconda’s 1978 underground development records.
A follow-up surface hole, SBM26-10, is drilling to test continuity up-dip at shallower depths.
Additional assay results from other vein systems in the same hole remain pending.
