Excelsior Mining (TSX: MIN) just completed a pipeline corridor at the Gunnison copper project in southern Arizona, which means that the company is on track to deliver its first copper production in Q4 2019.
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.
