Robinson is an open-pit copper mine containing three major zones: Tripp-Veteran, Liberty and Ruth. Robinson is owned and operated by Robinson Nevada Mining Company, a subsidiary of KGHM Polska Miedź S.A. (“KGHM”), and is located in White Pine County, Nevada, approximately 11 kilometers west of Ely.

The property is a mature mine site that has been actively mined from the late 1800s to 1978, from 1986 to 1999, and again from 2004 to the present.

Mining is conducted by conventional open-pit methods. The processing plant utilizes crushing, milling and flotation to produce a copper gold concentrate and a molybdenum concentrate. Concentrates are transported to storage facilities in Wendover, Nevada.
