Kemess Underground Copper-Gold Mine

A positive Preliminary Economic Assessment of the Kemess Underground Project in north-central B.C. reported that a 12 year mine life could be sustained. It is estimated that over 300 employment opportunities could be created over the life of the mine.

About This Project

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. In March 2012, the Kemess South mine ceased operations and activities are currently focused on reclamation and remediation work.

The results from the Kemess Underground feasability study outlined the development of an underground block/panel cave operation. Highlights of the study include(employs base case commodity price assumptions of $1,300/oz gold; $3.00/lb copper and $23/oz silver and F/X US$/Cdn$1.00):

• Average annual production of 105,000 ounces of gold at a net cash cost of $213 per ounce.

• Average annual copper production of 44 million pounds.

• An approximate 12-year mine-life.

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. In addition, analysis of the geotechnical data compiled during the 2010 drill season and previous drill programs indicate that the ore body is well suited to block caving.

As the Kemess Mine already has in place many of the permits required for the Kemess Underground Project, permitting is expected to be straightforward. All other infrastructure is in place and has been put on care and maintenance in anticipation of future use with the underground mine.

The proposed project is currently in the Pre-Application stage with the B.C. Environmental Assessment Office.
