Vancouver — Seabridge Gold is moving ahead with a prefeasibility study on its Courageous Lake gold property in the Northwest Territories.
The company has hired consulting firm Hatch to upgrade capital and operating cost estimates tallied in last year’s scoping study. The prefeasibility report is expected in July.
Based on preliminary reports, a large-scale, open-pit operation provides the best potential to recover the known gold resource at Courageous Lake. Metalurgical studies indicate that the refractory ore at Courageous Lake’s FAT deposit can produce a high-grade flotation concentrate that captures 93-94% of mill feed gold content at a relatively coarse grind. Hatch also estimated that a refractory process to treat this concentrate should ultimately recover 90-92% of mill feed gold content.
The Fat deposit hosts a measured and indicated resource of 48 million tonnes grading 2.06 grams gold per tonne, plus another 65.1 million tonnes grading 2.07 grams gold in the inferred category. Because of its impact on mine planning and project sizing, the junior will include the inferred resources in the latest Hatch study.
