Northisle Copper and Gold Inc. (TSXV: NCX) has announced preliminary metallurgical results from its Northwest Expo target within the North Island Project. The results demonstrate combined flotation and leach recoveries ranging from 88.7% to 92.6% for gold and flotation ranging from 68.7% to 87.7% for copper.
“We are very pleased to receive these positive metallurgical results at Northwest Expo within the North Island Project,” commented Northisle president & CEO Sam Lee. “Gold recoveries were significantly higher than initially anticipated and the clean copper concentrate remains very attractive with low deleterious elements. These results are a significant step towards accelerating the consideration of this gold-rich zone within our large, richly endowed porphyry district in 2024.”
The test programme was developed and managed by Ausenco Engineering Canada ULC and K-met Consultants Inc. who are both independent of Northisle. Base Metallurgical Laboratories Ltd. performed the test work in Kamloops, BC and is also independent of Northisle.
The strong gold recoveries averaged 89.8% using conventional flotation followed by cyanide leaching of the flotation tails. The copper recoveries averaged 80.2% with a 24.4% copper concentrate grade from locked cycle testing.
The initial mineral resource estimate for Northwest Expo completion is on track for Q1 2024. Upon completion, the company will review opportunities to optimize the North Island Project during Q2 2024, including an evaluation of various combinations of the Northwest Expo, Red Dog and Hushamu deposits as standalone, combined, or staged projects.
Northisle Copper and Gold is a Vancouver-based company whose mission is to become Canada’s leading sustainable mineral resource company for the future. Northisle, through its 100% owned subsidiary North Island Mining Corp., owns the North Island Project, which is one of the most promising copper and gold porphyry projects in Canada.
