Orvana Announces Preliminary Economic Assessment for Copperwood Project

Orvana Minerals Corp announced today the highlights of their 43-101-compliant Preliminary Economic Assessment of the Copperwood copper project, Upper Peninsula, Michigan, USA.

The study contemplates a 10-year underground operation that applies room-and-pillar mining. A trade-off study determined that the most economic mining method is the use of a continuous miner, which is commonly used in coal, salt, trona, and potash underground mines. Processing would be by froth flotation.

Copperwood is an attractive copper project and we will work towards applying for a mine permit next spring, said Roland Horst, Chief Executive Officer of Orvana.
The state of Michigan considers mining essential to their future economic growth, and Copperwood can definitely be a part of that growth. We are encouraged by the communities’ support to develop the deposit and look forward to working with them to put the mine into production
