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.
