Hudbay Minerals has announced the results of its preliminary economic assessment of its Mason copper project in Nevada United States.  They report the Mason project is a large greenfield copper deposit and is one of the largest undeveloped copper porphyry deposits in North America.  Mason’s measured and indicated resource estimates are approximately twice the size of Hudbay’s Constancia Peru and Rosemont Arizona deposits. The 2021 Mason preliminary economic assessment contemplates a 27 year mine life with average annual copper production of approximately 140 thousand tonnes over the first ten years of full production. The Mason deposit is planned to be a traditional open pit shovel/truck operation with a copper sulphide mineral processing plant.

Hudbay continues to compile and interpret historical data relating to its land package near Mason and once this is done they expect to complete a geophysical survey to refine exploration targets in preparation for a potential drilling campaign later this year.
