The McIlvenna Bay project is an underground copper and zinc mine located in Saskatchewan, Canada.
Canada-based mining company Foran Mining initially developed the project. A pre-feasibility study for the project was completed in April 2020, while a feasibility study was published in April 2022 and was later updated in March 2025. The study highlighted a mine life of 18 years for an initial investment of approximately C$987.4m ($696.7m).
In April 2026, Eldorado Gold completed the acquisition of Foran Mining, valuing the company at approximately C$3.8bn. Following the transaction, Foran became a wholly owned subsidiary of Eldorado.
In June 2026, Eldorado Gold announced the production of the first copper concentrate at the McIlvenna Bay project.
The site team is now concentrating on ramping up operations towards commercial production, anticipated in the third quarter of 2026, and a nameplate throughput capacity of 4,900 tonnes per day (tpd).
The project is expected to produce an average of 41 million pounds (mlb) of copper, 20,000oz of gold, 444,000oz of silver and 54mlb of zinc annually.
