Highlights:

Metal extraction of 96.1 - 98.5% nickel and 96.1 - 97.7% cobalt from bioleaching tests.
Bioleaching could offer much higher metal recoveries than flotation (29-51% nickel and 48-89% cobalt), significantly increasing the value of current mineral resources.
Both massive sulphides and rougher sulphide tails are amenable to bioleaching, potentially producing nickel/cobalt sulphates onsite for the battery manufacturing industry.
On-going tests are expanding to include high recoveries of copper and precious metals (palladium, platinum, gold, etc.).
Bioleaching is a promising, cost-effective, and eco-friendly technology for developing a low-carbon footprint green mine at the Ferguson Lake project.
