The Kemess Underground Project is located approximately 5.5 km north of the past producing Kemess South mine in north-central British Columbia. During its mine-life, the Kemess South mine produced close to 3 million ounces of gold and over 300 million pounds of copper.
The results from the Kemess Underground feasibility study outline the development of an underground block cave operation with average annual production of 105,000 ounces of gold and 44 million pounds of copper at cash costs of $213 per ounce of gold, net of by-product credits, over a mine-life of approximately 12 years using base case commodity price assumptions of $1,300 per ounce for gold, $3.00 per pound for copper and $23 per ounce for silver and an exchange rate of US$/CDN$1.00.
The envisaged Kemess Underground block cave operation would leverage the existing infrastructure and mill facilities at the Kemess South mine, currently on care and maintenance, including a permitted area for tailings storage in the Kemess South open pit.
Over the next two years, the Company intends to pursue strategies at Kemess that enhance intrinsic value, such as permitting and additional exploration outside existing reserves, to further develop the optionality of this asset.
