Key Property

Montanore Silver-Copper Project

The wholly-owned Montanore Project is located twenty-three miles south of the town of Libby, Montana, and hosts one of the world’s largest Silver-Copper deposits. It is located near one of the most prolific silver regions in the U.S. which has produced more than 1 billion ounces of silver historically. The project has excellent infrastructure for mine development close at hand; with road, rail, low cost power, and abundant labor residing in a the mining friendly jurisdiction.

The deposit is categorized as a stratabound sediment-hosted silver-copper deposit, and is one of three major deposits in the area, which include, the Troy Mine and Rock Creek deposits. In-situ mineralization is estimated at more than 230 million ounces of silver and nearly 2 billion pounds of copper. These mineralized zones strike northeast, dipping to the northwest, with only a small portion of the mineralized zone exposed at the surface. This makes the Montanore project best suited as an underground operation. The copper and silver values are carried predominately in the minerals bornite, chalcocite, chalcopyrite and native silver in varying proportions.

The project has undergone extensive engineering, and is designed with an initial production capacity of approximately 12,500 tons per day, estimated to yield 8 million ounces of silver and 60 million pounds of copper annually. The project benefits significantly from past work which included: 70,000 feet of exploration drilling, advanced stage engineering and mine planning, and construction of a 14,000 ft. underground evaluation adit.
