- Supergene and hypogene porphyry copper mineralization targets in southern portion of multi-porphyry-center Yerington mining district
- Tertiary faults have dramatically dismembered and extended district - a cluster of large porphyry Cu(-Mo) systems centered on a Jurassic-age granitic pluton
- Fault-bound deposit pieces include: past-producing Yerington and McArthur mines (Anaconda), and the undeveloped Bear-Lagomarsino and Ann Mason deposits
- Much of district remains covered by post-mineral sedimentary and volcanic rocks
- Extensive geologic work in the district by Anaconda geologists in the 1960's, 70's and 80's produced highly-constrained structural and geologic models for the district, and these provide effective exploration tools and have helped illuminate additional targets for exploration
- Dike swarms and skarn deposits in southern part of Yerington district highlight presence of another, yet-undiscovered, porphyry center
- Multiple lines of geologic evidence supported by a refined structural interpretation points to structurally offset porphyry center under volcanic and sedimentary cover on BCE property
