Claim Map: Red Chris

Imperial's wholly owned Red Chris copper/gold property is located 80 kilometres south of Dease Lake in northwest British Columbia. The property covers a total area of 29,482 hectares and is comprised of five 30 year mining leases covering 5,141 hectares and 83 mineral claims encompassing 24,341 hectares. The Red Chris project was issued a Mines Act permit in May 2012 by the Province of British Columbia.

First Concentrate Shipment

The first load of copper concentrate from the Red Chris mine was loaded at Stewart Bulk Terminals in Stewart, BC on April 11, 2015. This is the first shipment, and the inaugural voyage, for the new ship M/V Edward Oldendorff.

Site Commissioning

Commissioning activities commenced in November 2014. In February both the SAG and ball mill drive systems were operated at 100% load factors. As a result, the flotation circuits and secondary regrind mill are being commissioned with low grade ore, resulting in the first production of copper concentrate on February 17. The commissioning process will continue over the next few months.


Mining activities have commenced in both the East and Main zones, utilizing the P&H 2800 electric cable shovel and CAT 793 haul truck fleet. Mining will initially be from these two pits, which will eventually form one large pit.

Moving Forward

The Company continues to work closely with the Tahltan First Nation, whose cooperation has been instrumental in the construction of the Red Chris mine - an important milestone for the Tahltan, Imperial and the Province of British Columbia.

A third party review of the tailings dam was completed in October 2014 by consultants retained by representatives of the Tahltan Nation. Red Chris and the Tahltan Central Council are working together to develop a work plan to implement the recommendations contained in the review. We are also working with the representatives of the Tahltan Nation to finalize an Impacts & Benefits Agreement.

Sale & Transfer of Power Line

Imperial completed and closed the sale of the 93 kilometre 287kV Iskut extension of the Northwest Transmission Line to BC Hydro for $52 million on December 19, 2014.

Power Line Construction

Power was delivered to the Red Chris mine on November 7, 2014. The Iskut extension of the Northwest Transmission Line (NTL) was built by Highway 37 Power Corp., a subsidiary of Imperial, from the terminus of the NTL at the Bob Quinn substation to a newly constructed substation at Tatogga Lake. A 16 kilometre 287kV power line which connects the Red Chris mine to the Tatogga substation was built by Imperial.
