The building of the two-mile high-density polyethylene pipeline corridor connecting the Johnson Camp Mine processing facility to the production wellfield began in January.

“We are now more than 90% finished in terms of the entire construction process, and we look forward to completing the remaining elements over the next month,” Stephen Twyerould, Excelsior’s CEO and president, said in a media statement.

The 9,560-acre Gunnison project hosts the North Star deposit which, according to Excelsior, contains a measured and indicated copper resource of 4.99 billion pounds.

The mine is expected to produce 2.2 billion pounds of pure copper cathode over its 24 year lifespan.
