Trilogy Metals.

Trilogy Metals has reported an initial inferred cobalt resource of 77 million lb at its Bornite copper-cobalt project in northwest Alaska. Ongoing metallurgical studies indicate that cobalt occurs predominantly as cobaltiferous pyrite, which would preferentially report to copper tailings following copper flotation. These studies indicate that a cobalt product may be produced on site and therefore justify reporting an initial cobalt resource in addition to the existing 5.5-billion-lb inferred copper resource.

Over the next few months, Trilogy will complete flotation test work focused on concentrating cobalt into a pyrite-rich product that can be considered for further upgrading and recovery of cobalt metal at the Bornite site.

The 77-million-lb contained cobalt inferred resource at Bornite is one of the largest cobalt resources in North America. (
