Center of Section 9, T29N-R10E

A large skarn area, located 300' southwest of the Vesper Peak Ridge Crest.

It worked limestone lenses altered by contact metamorphism forming bodies up to 70' long by 50' wide. Developments include shallow opencuts.


Tectonics: Cascade Volcanic Arc

Commodity: Nonmetallics are the principal commodities

Deposit: Deposit is formed by a lens of limestone that was altered by contact metamorphism

Deposit type: Skarn Cu

Geology: Area is mapped As chert on 100,000-scale map. Limestone is probably small sliver of marble of eastern melange belt within the chert

Rock formation(s): Squire Creek Stock And Related Rocks
Eastern Melange Belt
