Pine Cove Mill
Location
The Point Rousse Project is located within the Baie Verte Mining District, on the Point Rousse/Ming’s Bight Peninsula, in the northern portion of the Baie Verte Peninsula, approximately 6 km northeast of the Town of Baie Verte, in north central Newfoundland, in the Province of Newfoundland and Labrador. The Point Rousse Project covers an area of over 54 km2 and has significant access, mining, milling and tailings infrastructure.
Assets and Infrastructure
Highlights include the fully permitted and operational Pine Cove gold processing plant, large capacity in-pit tailings storage facility, hydro electric power, access roads and a deep water port.
The Pine Cove mill operates as a grind/flotation circuit followed by leaching. Comminution is via a two stage crushing plant followed by a 10’ x 14’ primary ball mill, which is rated for an average of 1,300 tpd of ore. Cyclone overflow feeds the flotation circuit, with three column cells for roughing, one scavenger/staged reactor cell, and one cleaner cell. The concentrator has a flotation circuit which produces a gold-pyrite concentrate that advance to the leach circuit. Flotation concentrate is thickened in a 4.5 m diameter thickener and reground in a 5.5’ x 10’ diameter ball mill down to a P80 grind size of 20 microns. Leaching is conducted in a series of four 75 cubic metre, mechanically agitated leach tanks. Two drum filters and a Merrill-Crowe circuit are used for gold recovery from the pregnant solution. Cyanide destruction of leach tailings is achieved through the Inco SO2 process. Tailings are stored sub-aqueously in the Pine Cove open pit.
The Pine Cove mill was restarted in February 2025 after a two year period of care and maintenance. The mill is processing existing mineralized stockpiles and is now producing gold doré for sale to gold refiners. Processing will transition to the high grade Hammerdown Gold Project in the second half of 2025.
Waste rock from historic mining operations is crushed, screened and shipped to international markets as construction aggregate by Shoreline Aggregates, a local firm with extensive history and experience in the Baie Verte district. Aggregate products are shipped from a deep water port that can accommodate Panamax class vessels.
