Cygnus aims to prioritise resource growth of the Chibougamau copper gold project through an aggressive exploration drilling campaign focusing on resource extension, and brownfield and greenfield targeting, with the application of modern geophysics.
The Jaculet mine is located 2.5 kilometers by road from the Copper Rand mill and was in operation from 1960 to 1971 producing a total of 1,091,000 tonnes at 1.84% Cu, 1.44 g/t Au and 6.85 g/t Ag (20,074 tonnes of Cu and 1.57 tonnes Au)1. Jaculet was mined to a depth of 366 meters (1,200 feet) and the shaft was deepened to 500 meters (1,650 feet) in 1972.
The Jaculet mineralized system consists of two distinct subparallel shear zones separated by approximately 200 meters, known as Zone 1 and Zone 2, which both remain open at depth with very little development below 366 meters.
The Cedar Bay mine operated from 1958 to 1990 and produced 3.9 million tonnes grading 1.56% Cu and 3.22 g/t Au. The ore from the mine was processed at the Copper Rand mill located 5 kilometers by road. The deposit was mined to a depth of 670.5 meters and the existing shaft extends to a depth of 1,036 meters. Doré Copper completed four holes (including wedges) totaling 4,842 meters in 2018 The current Mineral Resources at Cedar include Indicated resources of 130,000 tonnes at 9.44 g/t Au and 1.55% Cu, and Inferred resources of 230,000 tonnes at 8.32 g/t Au and 2.13% Cu. During 2020, Doré Copper completed 9,025 meters of drilling.
The Southwest Zone is located 300 meters southwest of the Cedar Bay mine Main Zone and was partially developed in late 1960s on two levels (114 meters and 200 meters) right to the property limit with Patino Mining at the time. The potential extension of the Cedar Bay Southwest Zone along strike to the southeast was never tested by Patino Mining and subsequent companies that controlled that ground.
The Doré Ramp (previously called Lac Doré Ramp) gold-copper deposit is located approximately 2.5 km by road of the Copper Rand mill. It was drilled in a few different phases from 1984 to 1992 with a total of 47 drill holes from surface. A double ramp approximately 1 kilometer long was excavated in 1991-92 to a vertical depth of 160 meters, followed by an underground drilling campaign of 46 holes totaling 10,200 meters testing the deposit to a depth of 240 meters. Only five holes tested the deposit between 300 and 600 meters. No subsequent exploration programs were carried out on the Doré Ramp deposit.
