Doré Copper has consolidated a large land package of brownfield projects in and near Quebec’s Chibougamau prolific mining camp that has produced 1.6 B lbs of copper and 4.4 M oz of gold. The properties include 13 former mines, deposits and resource target areas, all within a 60 km radius of its Copper Rand mill.
The Copper Rand mill was constructed in 1959 and then updated and expanded in the 1970s, 1980s and then again in the early 2000s. The mill last operated in 2008.
The mill is connected to the Quebec energy grid and has a power supply of 25 MW at 25 kV. Water used for the process would be recycled from the tailings management facility. The site has a substation, core shack, laboratory, warehouse, and office complex. The process plant building occupies a surface area of 2,830 m2 and consists of crushing, fine ore storage, grinding, gravity recovery of particulate gold, flotation of a copper concentrate, thickening, and filtration. The concentrator had an installed milling capacity of approximately 2,700 tpd. The tailings were pumped two kilometers at a level elevation to the Copper Rand tailings management facility.
