Development Highlights
The Troilus deposit lies within the eastern segment of the Frotêt-Evans Greenstone Belt, and it is primarily a gold-copper deposit, but contains minor amounts of silver, zinc, and lead.
The project encompasses the historic Troilus Mine, which was an open pit operation producing gold, copper, and silver continuously from 1996 to 2009. The mine produced more than two million ounces of gold and approximately 70,000 tonnes of copper.
A Feasibility Study announced in May 2024 considers an open-pit mine processing 50,000 tonnes per day with life-of-mine average annual payable gold production of 244,600 oz, 17.3 Mlb of copper and 446,700 oz of silver over an expected 22-year mine life.
Troilus announced positive metallurgical results from a pilot plant testing program completed for Zone X22, part of the main mineral reserve pits at Troilus, in June 2024. Metallurgical recoveries of 91.4% for gold, 94.0% for copper, and 87.2% for silver were achieved from sample X22-1.
