Geologic setting

Geologic description

The Stone Lode prospect is a poorly known, but promising gold prospect in skarn near a limestone/monzonite contact; it is geologically very similar to Nixon Fork Mine (MD062). Mineralization consists of garnet-rich and wollastonite-idocrase-epidote skarn that replaces an Ordovician limestone near the margin of a small monzonite body that is currently undated.
