Johnny Lee Deposit; Lowry Deposit

The Black Butte ore body is defined by laterally extensive, shale-hosted, massive-pyrite horizons. Black Butte contains at least 10 mineralized sulfide horizons, five of which contain copper. Three of these copper-bearing sulfide horizons are of greatest interest to the company at the time of writing, and are referred to as the Lower, Middle, and Upper Sulfide Zones (LSZ, MSZ, and USZ, respectively). The USZ and LSZ are the dominant mineralized zones in the Johnny Lee Deposit, and the MSZ is more important in the Lowry Deposit.
