Osisko Metals Inc. May 8 said its winter drilling continues to confirm historical zinc mineralization at its newly acquired Pine Point zinc-lead project in Northwest Territories.
Located near the community of Hay River, the Pine Point project benefits from substantial infrastructure that includes road access, rail head in Hay River and hydro-electric power available on site. A preliminary economic assessment completed in 2015 examined several development scenarios and settled on a mining plan where 10 open-pit deposits are mined in sequence.
The deposits included in the mine plan host 25.8 million metric tons of measured and indicated resources averaging 2.9 percent zinc and 1.1 percent lead, plus 3.7 million metric tons of inferred resources averaging 2.9 percent zinc and 0.8 percent lead.
Roughly 4,000 to 6,800 metric tons of mineralized material would be mined per day and fed into dense media separation plants for pre-concentration prior to being trucked to a centralized 1,800-metric-ton-per-day mill to produce lead and zinc concentrates with a more traditional mining and flotation circuit.
The concentrate will then be trucked about 65 kilometers (40 miles) to a railway facility at Hay River. This method is similar to that used by Cominco (now Teck Resources) when it operated a mine at Pine Point from 1964 to 1987.
