Northisle Copper and Gold Inc. (TSX-V: NCX) (“Northisle” or the “Company”) is pleased to announce that it has commenced a metallurgical testing program covering the Hushamu and Red Dog deposits, as well as the Northwest Expo target on its North Island Project (the “Project”).

Sam Lee, President and CEO of Northisle commented, “We see the potential to improve both copper and gold recoveries at the project overall and are also keen to determine the potential preliminary recoveries from Northwest Expo. This program is a key element of our focus on driving project value while being efficient with shareholder capital.”

Metallurgical Program Details

Northisle has retained Kelly McLeod, P.Eng. who, together with Ausenco Engineering Canada Inc., have designed a comprehensive metallurgical program for the Project to assess the feed characteristics and metallurgical recovery performance of samples from the Hushamu and Red Dog deposits, as well as the Northwest Expo target in support of future technical studies. Laboratory testing will be conducted by Base Metallurgical Laboratories Ltd.

The program will also evaluate the use of enhanced process technologies including coarse particle flotation, alternative grinding and flotation technologies and copper / molybdenum separation testing, which will determine the potential for production of a saleable molybdenum concentrate. Finally, in order to evaluate the potential for improved gold recoveries, the program will also consider pyrite concentrate leaching based on balancing the gold content between the copper concentrate and pyrite concentrate.

Initial work on Northwest Expo will seek to determine preliminary recovery estimates based on the 2021 drill samples with additional testing to be completed following the resource definition drilling program at Northwest Expo, contemplated for the first half of 2023.
