Geology

Moonlight is at the northern terminus of the Walker Lane mineral belt in Plumas County, California. Mineralization at the Moonlight project is hosted by a large and complex Jurassic intrusive stock regionally located near the triple point junction of the Cascade, Sierra Nevada and Basin and Range provinces.

The mineralization has been classified as a porphyry-copper type system but does not exhibit many features characteristic of these systems. Additionally, it is an unusual low-sulfide system containing only sparse amounts of acid-generating sulfide minerals such as pyrite.
