Lead- and zinc-bearing exhalite, Dolly Varden silver-gold project. PRECIOUS METALS In April, Banks Island Gold Ltd. started production at the Yellow Giant gold-silver mine. Currently mining under- ground at the Bob and Tel developments, mill throughput is 200 tonnes per day. In its first five months, the operation sold over 220,000 grams of gold and 575,000 grams of silver. Pretium Resources Inc. released an updated feasibility study for its Brucejack underground project. The proposed 18-year mine has an estimated 230 million grams contained gold in proven and probable categories. The project is in the review stage of provincial environmental assessment. Deep drilling at the Valley of the Kings continues to intersect high-grade gold over 0.5- to two-metre intervals. Ascot Resources Ltd. focused exploration on the past-producing Premier gold-silver mine, drilling a structural zone 30 to 150 metres wide. Dolly Varden Silver Corporation and Hecla Mining Company continued drilling into the fall at the past-producing Dolly Varden silver-gold project. Drilling intersected deep mineralized horizons, proving geological con- cepts generated by fieldwork earlier in the year. At the nearby Homestake Ridge, drilling by Homestake Resources Corporation extended the strike length of the Slide zone to 800 metres. The Slide zone, discovered during 2013 drilling, is considered analogous to the main Homestake Silver deposit. Main Homestake, Homestake Silver and South Reef zones contain an indi- cated 20 million grams of silver and 3.8 mil- lion grams of gold, and an inferred 633 million ounces of silver and 28.3 million ounces of gold.
