Alberta Star Intersects Base Metals, Silver at Echo Bay

Alberta Star Development (ASX-V, ASXSF-O) has intersected multiple zones of base metal and silver mineralization on a prospect near the old Echo Bay silver mine on the eastern shore of Great Bear Lake, in the Northwest Territories.

Alberta Star is looking at the Echo Bay, Eldorado, and Contact Lake areas for iron oxide-copper-gold mineralization, where intermediate to felsic plutonic rocks intrude a pile of andesites. Polymetallic veins in the area produced silver, base metals, uranium and radium from the 1930s through to the 1980s.

Recent drilling showed multiple mineralized zones, mainly 1.5 to 3.5 metres in core length, but locally much wider. The intersections showed copper, lead, zinc and silver mineralization, with occasional trace amounts of nickel or cobalt.

Among the better results was a 24.8-metre interval that averaged 2.5% lead, 0.49% copper, 0.31% zinc and 26.5 grams silver per tonne, with 0.03% nickel and 0.6% cobalt. That was in a drill hole with eight other mineralized intersections, ranging from 1.5 metres to 31.8 metres in length, but generally showing grades of 1-3 grams silver per tonne with a fraction of a per cent in copper and zinc.

Another hole cut 7.5 metres grading 0.18% copper, 0.12% zinc, 0.04% lead and 1.4 grams silver, while a third intersected 15.5 metres of 0.54% zinc, 0.2% copper, 0.09% lead and 3.3 grams silver per tonne.

Further results are pending, with samples from four other drill holes in the lab.
