The Mason project is located in west-central Nevada, approximately 75 km southeast of Reno within the historical Yerington Mining District. Mason is a copper-molybdenum porphyry deposit hosted by granodiorite and quartz monzonite. Projected to the surface, the mineralization greater than 0.15% copper covers an area approximately 2.3 km by 1.3 km. At depth, it extends more than a kilometre and remains open in most directions.

In April 2021, Hudbay announced a positive Preliminary Economic Assessment (“PEA”) that contemplates an open pit operation with a 27-year mine life with average annual copper production of approximately 140,000 tonnes over the first ten years of full production. At a copper price of $3.10 per pound, the after-tax net present value using a 10% discount rate is $519 million.

The PEA and mine plan were based on a revised resource model which was used to publish Hudbay’s first compiled updated resource estimate for Mason. The updated Measured and Indicated Mineral Resources at Mason consist of 2,219 Mt at 0.32% copper and 67 g/t molybdenum (NSR cut-off of $6.25/tonne), effective January 1, 2021.
