to the site to supply power to the Project. In addition to the site infrastructure, it is assumed that a 135 km, 230 kV transmission line will be constructed from the BC Hydro Glenannan substation near Endako, B.C. Potentially acid generating waste rock, along with tailings, will be deposited into the TSF located to the north/northwest of the open pit.Īt closure, all buildings will be removed, disturbed lands rehabilitated, and the property returned to otherwise functional use according to future approved reclamation plans and accepted practices at the time of closure. Overburden and non potentially acid generating waste rock not required for construction will be placed in stockpiles adjacent to the open pit. Most of the waste material sourced from the pit will be used for construction of the tailings storage facility (“TSF”) or placed in the TSF itself. The material will be sourced via conventional open pit mining methods, initially targeting high-grade, near-surface ore for processing, with lower-grade material being stockpiled for processing at the end of the mine life. The proposed mine plan involves mining 334 Mt of ore, 584 Mt of waste rock and 83 Mt of overburden. A combined gravity circuit and whole ore leaching (WOL) will be used for recovering gold and silver. The ore processing facilities will be expanded to achieve 33,000 tpd (12 Mtpa) starting in year 6 with a final expansion to achieve 55,000 t/d (20 Mtpa) starting in year 11 of operation. The Blackwater Project will comprise the construction, operation, and closure of an open pit gold and silver mine and ore processing facilities commencing with a nominal milling rate of 16,000 t/d (6.0 Mtpa). Surface rights over the Project area are controlled by the Crown. Artemis has a 100% recorded interest in 329 mineral claims covering an area of 148,902 ha distributed among the Property and the Capoose, Auro, Key, Parlane and RJK claim blocks. The Project is accessible by major highway and access/service roads. The Project is located in central British Columbia, approximately 160 km southwest of Prince George and 446 km northeast of Vancouver.
