Published

TORONTO, March 21, 2019 (GLOBE NEWSWIRE) -- Hudbay Minerals Inc. ("Hudbay" or the "company") (TSX, NYSE:HBM) announced today that it has received the approved Mine Plan of Operations ("MPO") for the Rosemont project from the U.S. Forest Service. The issuance of the MPO is the final administrative step in the permitting process.

"Receiving the MPO is an important milestone that completes the permitting process at Rosemont," said Alan Hair, Hudbay's president and chief executive officer. "With the receipt of the Section 404 Water Permit, an agreement to consolidate 100% ownership and receipt of the approved MPO, Hudbay continues to move the project forward. Rosemont is now a fully permitted, shovel-ready copper project and we look forward to developing this world-class asset."

Rosemont, located in Arizona, is one of the world's best undeveloped copper projects delivering a 15.5% after-tax unlevered IRR at a copper price of $3.00 per pound based on the 2017 Feasibility Study published by Hudbay. Rosemont is expected to produce approximately 127,000 tonnes of copper annually at a cash cost of $1.14 per pound (net of by-product credits) over the first 10 years of operations.
