Map highlighting Kemess’s location in British Columbia, Canada.

Overview

The Kemess Project is located in the highly prospective Toodoggone District in the northern interior of British Columbia. Kemess was a past producing mine which benefits from significant infrastructure already on-site, including: a 380 km, 230 kilovolt power line; a 50,000 tpd nameplate processing plant in need of some refurbishment and equipment replacements; “mothballed” site infrastructure including a water treatment plant, camp, administration facilities, air strip, truck shop and warehouse which will require some refurbishment; and tailings storage using the previously mined pit as well as an existing tailings facility, which is capable of expansion.

In addition, Kemess has several permits in place from the site’s previous operations and development plans. Amendments to existing permits will be required to align with the updated plan. Centerra also benefits from established relationships with its First Nations partners through existing impact benefit and other agreements, supported by ongoing discussions regarding the planned development strategy.

Kemess as a Potential Second Long-Life Gold-Copper Asset in British Columbia

Centerra is advancing technical studies for a potential gold-copper mine with an initial 15-year mine life and is progressing work a Pre-Feasibility Study which is expected to be completed in 2027.

Kemess represents a strategic opportunity as Centerra continues to advance its self-funded organic growth pipeline. Kemess has the potential to become Centerra’s second long-life gold-copper asset in British Columbia, complementing Mount Milligan and strengthening its presence in the Toodoggone, one of the most prospective mining jurisdictions in North America, supported by strong economics and significant exploration upside potential.
