'Short, but profitable' life for Rainy River gold mine.

New Gold's Rainy River Mine will have a shorter life span than originally anticipated.

The Toronto mining company posted a new life-of-mine plan of its open pit and underground Intrepid Zone operation, 50 kilometres northwest of Fort Frances.

The new mine plan emphasizes creating positive cash flow over a "shorter, but more profitable mine life."

The previous estimated life span was 14 years after mining operations began in late 2017.

The updated one anticipates closure plans kicking in by 2028.

New Gold undertook mine optimization studies on its two main operating assets at Rainy River and New Afton in B.C. The process revolved around eliminating those gold zones that don't meet the company's profitability threshold.

The mine plan built on a gold price of US$1,275 per ounce.

For surface mining, that will translate to a smaller pit shell to reduce the amount of waste rock to ore until pit operations cease in 2024.

Construction continues underground, with operations slated to begin in 2022 and hitting peak production between 2025 and 2027.

The company said the potential remains to continue mining beyond 2028, but gold prices need to support doing more underground development or exploration.
