Blackwater is to be linked to the BC Hydro grid, which is powered by hydro-electricity offering it with a sustainable supply of low-carbon energy, with the potential to supply gold and silver with one of many lowest GHG emissions from an open pit on the planet.
The venture might be developed in phases as an open pit and carbon-in-pulp processing plant. Preliminary capital necessities might be C$592 million for section one with a mill capability of 5.5 million t/y and an annual output of 248,000 oz. of gold. Over the 23-year lifetime of the mine, throughput might be elevated to twenty million t/y with two additional enlargement phases.
The Blackwater gold venture has an after-tax web current worth (5% low cost) of C$2.2 billion, an inner charge of return of 35%, and a payback interval of two years.
The deposit is estimated to include 251 million measured and indicated tonnes grading 1.04 g/t gold and eight.3 g/t silver for 8.4 million oz. gold and 68 million oz. silver. The inferred estimate is 5.6 million tonnes at 0.79 g/t gold and 26 g/t silver, containing 142,000 oz. gold and 4.6 million oz. silver. These numbers replicate a 0.5 g/t gold cut-off.
