Our Moonlight-Superior Copper Project in Plumas County, California includes copper resources with silver and gold credits in three deposits – Moonlight, Superior and Engels. A 2018 Preliminary Economic Assessment demonstrated positive economics at US$3 copper for the Moonlight deposit, which has a NI 43-101 indicated resource of 252 million tons at 0.25% copper and an inferred resource of 109 million tons at 0.24% copper.
Legendary Copper in California
We are now preparing to initiate an expansion drill program to include the higher-grade Superior and/or Engels deposits to further improve the project’s economics. The Superior deposit has a NI 43-101 resource of 54 million tonnes at 0.41% copper, and the Engels deposit has an unconfirmed historical resource of 19 million tons at 0.63% copper sulfide at surface.
