ALASKA - NIBLACK MINING of Vancouver has begun portal construction and tunnelling at its Niblack VMS copper-zinc-gold-silver project in southeast Alaska. The underground program includes 1,800 metres of ramp development for drilling. The areas beneath the gold-rich base metal Lookout zone, the Mammoth zone and new zones of massive sulphides will be tested.

Mineralization in the Lookout zone has been traced from the top of Lookout Mountain to 500 metres below surface, and the zone is open at depth. The new portal, measuring 4.3 x 4.6 metres, is collared at the base of Lookout Mountain at an elevation of 120 metres. Underground development will include a 1,000-metre main access tunnel that will pass through the deepest portion of the Lookout zone, and three crosscuts, each approximately 300 metres long.

Mineralization at Niblack is hosted by a thick sequence of rhyolite that exhibits widespread alteration and mineralization, according to Niblack Mining. Distribution of the six main massive sulphide occurrences - the historic Niblack mine, Dama zone, Lindsy zone, Trio zone, Mammoth zone and Lookout zone - is controlled by fold repetition of the rhyolite sequence, with the Lookout and Mammoth zones occurring on opposite limbs of a large synclinal fold.
