Name of the Project
Mason copper project.

Location
Nevada, in the US.

Project Owner/s
Hudbay Minerals Inc.

Project Description
If brought into production, Mason is expected to become the third-biggest copper mine in the US.

The project has total measured and indicated resources of 2.22-billion tonnes grading 0.29% copper, 67 g/t molybdenum, 0.03 g/t gold and 0.63 g/t silver.

A preliminary economic assessment (PEA) has shown that the Mason project has the potential to more than double Hudbay’s current copper production levels.

The PEA envisages a 27-year mining operation, with average copper production of about 140 000 t/y over the first ten years of full production.

The mine plan includes the construction of a 120 000 t/d conventional flotation concentrator.

The mine plan includes 1.1-billion tonnes at 0.34% copper-equivalent, 98% of which is from the measured and indicated categories.
