The historic Pine Point Mine was the largest and most profitable zinc-lead mine in Canadian history. Located on the south side of the Great Slave Lake 129 kilometers (80 miles) south of Yellowknife and 40 kilometers (25 miles) east of Hay River, the historic Pine Point Mine extracted over 64 Million tonnes of ore at a grade of 7.0% zinc and 3.1% lead between 1964 and 1987.The Pine Point Mine was forced to shut down in 1987 due to the high costs of maintaining a townsite, exhaustion of near-plant resources, and low metal prices ($0.35 Zn, $0.27 Pb). Tamerlane has learned from the problems encountered by previous operators, and is now proposing to mine the Pine Point Mine’s orebodies using a variety of open cut and underground mining methods. No townsite will be needed, and the mill site will be centrally located to all current and future ore deposits at the Pine Point Mine.
In order for mining in the area to be successful, the water table needs to be controlled and stabilized, and for this Tamerlane proposes using known technology to establish a perimeter of frozen water and rock around each deposit. This will allow for a much more economic extraction of ore from the Pine Point Mine property.
Currently, Tamerlane controls a total of 175 km2, including both the historic Pine Point Mine property as well as a contiguous property to the west originally explored by Westmin Resources (Westmin). The property includes a large unmined resource left behind following the Pine Point Mine’s closure in 1987, as well as historical exploration work conducted by the mine’s previous operators. The property contains 35 known potentially mineable deposits. The R190 deposit is the initial focus of Tamerlane’s Pine Point Project.
Tamerlane has found that the Pine Point Mine can indeed be a profitable venture, if a lesson is learned from the site’s history. Tamerlane has been diligently modeling the mine site from all facets, and is confident that the Pine Point Mine will be restored to its previous position of prestige.
