In November 2020, Granite Creek Copper completed its acquisition of Copper North Mining Corp, combining its Stu Cu-Au Project (now “Carmacks North”) with the PEA-stage Carmacks Cu-Au-Ag project, thereby consolidating the southern half of the productive and highly prospective Minto Copper Belt in Canada’s Yukon Territory. This 100%-owned, 176-square-kilometer property is on trend with Pembridge Resources’ high-grade Minto Copper-Gold Mine to the north and its excellent access to infrastructure includes the paved Yukon Highway 2 within 60 km as well as grid power within 12 km.

Summary:
The Carmacks copper-gold deposit is similar to the Minto deposit, located 50 km to the northwest (Sinclair, 1976; Pearson, 1977), except that the Minto deposit is flat lying and primarily a sulphide deposit. A number of theories for the genesis of the Carmacks deposit have been postulated over the years and by different operators. The Cu-Au- Ag metal tenor and association with Late TriassicEarly Jurassic granodiorites would appear to suggest a link between mineralization at Carmacks and the porphyry copper deposits of the same age that occur across British Columbia. However, the linear deposit shape, lack of mineralized material-stage veining and lack of porphyry alteration show clearly that the Carmacks copper deposit is not a classic porphyry system. Evidence from the drilling campaigns suggests the deposit was formed by assimilation of older, copper bearing volcano-sedimentary rocks into the Jurassic Granite Batholith. These “rafts” of mineralized rock would have been variably metamorphosed, and in places completely assimilated into the granodiorite. The volcano-sedimentary rafts would tend to pull apart along bedding planes forming large tabular sheets as observed in Zones 1, 4, 7, 7A, 8, 12, 13 and 2000S. Evidence suggests the sulphide mineralization has been remobilized out of the rafts into the surrounding diorite. At a later time, when the upper parts of the batholith where eroded and the rocks were exposed to the atmosphere and meteoric waters, the sulphide mine ........
Summary:
The Carmacks project will be developed as an open pit mine. Mining will be conducted on two 12- hour shifts per day for 335 days per year. It was specified that this was to be envisioned to be conducted with three mining crews using a 20-day on/10-day off rotation.
Four mining phases were designed for the Carmacks Project. Inter-ramp slope angles are 52.6°. The design is also based on 10 m mining benches in a double bench configuration for final walls. The main road is 25 m wide at a maximum grade of 10%. This will accommodate trucks of approximately 90 t such as Caterpillar 777 class trucks.
