The Point Rousse Project covers an area of over 54 km2 and has significant access, mining, milling and tailings infrastructure. Highlights include the fully permitted Pine Cove gold processing facility, large capacity in-pit tailings storage facility, hydro electric power, access roads and a deep water port facility.
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 1,350 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 idled in March 2023 and is currently on a care and maintenance program.
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.
