SnapshotFor nearly 40 years, Golden Sunlight was one of cornerstone operations in Montana, producing more than 3 million ounces of gold before mining ended in 2019.

On February 11, 2022, the pioneering Tailings Reprocessing Project at Barrick’s end-of-life Golden Sunlight Mine was officially opened.

As of December 2024, the tailings reprocessing project at Golden Sunlight continues to ramp up. The project progressed slower than planned as Barrick continues to refine the process and flow sheet and full production is now expected in the second half of 2025. The reprocessing of high-sulphide tailings eliminates the need for perpetual water treatment, provides a valuable fuel source for the Carlin roasters and facilitates proper closure.
