Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Workings): 3 Adits

Comment (Geology): 1 Set Fractures: Strike NW, Dip 60-75 Deg NW; Second Set: Strike NW, Dip Steeply SW.

Comment (Deposit): IBMG lists the Fourth of July Deposits as being the same as this record. They do plot in the same TRS, so data consolidated into this record.
