A former Cr occurrence/mine located in sec. 29, T15N, R11E, MDM, about 4.2 km NNE of Hughes Mill, S of Pagge Creek and E of Sugar Pine Road, on National Forest land. MRDS database accuracy for this location is not stated. Apportioned, on basis of additional information, from combined production of 2 or more properties.
This is one of many Cr deposits/mines placed into a very large area termed the "Forest Hill Divide area" by Rynearson. That area is based on geological and topographic considerations versus mining districts and overlaps several defined districts. Those Cr occurrences within mining districts are listed under their respective districts, the remainder are listed under Rynearson’s "Forest Hill Divide area."
This deposit occurs in the easternmost of 3 sub-parallel belts of ultramafic rocks that trend northward across Placer County. Local rocks include ultramafic rocks, chiefly Mesozoic, unit 2 (Western Sierra Nevada and Klamath Mountains).
