Nevada, the Turquoise Ridge complex also increased year-over-year attributable measured and indicated resources by 1.5 million ounces2 mainly off the back of a revised geological model at Turquoise Ridge Underground.
Copper mineral reserves for 2021 are estimated using a copper price of $2.75 per pound and mineral resources are estimated at $3.50 per pound, both unchanged from 2020.
Attributable proven and probable copper reserves were 12 billion pounds2 at an average grade of 0.38% in 2021. Attributable measured and indicated copper resources were 24 billion pounds2 at an average grade of 0.35%, and inferred copper resources were 2.1 billion pounds2 at an average grade of 0.2% in 2021. Mineral resources are reported inclusive of reserves.
Mineral resource management executive Rodney Quick said, “The geological improvements and remodeling are now starting to make a real impact. The incorporation and integration of mine design optimizations are also driving many of the mineral resource additions. A sound understanding of the geological orebody has been integrated with a better understanding of local variations in the geotechnical and metallurgical disciplines to produce integrated and optimized mine designs.”
