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 (Deposit): DISSEMINATED AND STREAKY CINNABAR OCCURS IN LIGHT GREY OPALITE. THE OPALITE IS PROBABLY A REPLACEMENT OF TUFF AND -PEBBLY TUFF. THE FINE-GRAINED OPALITE UNIT MAY BE ONLY 1-2 M T-HICK, ALTHOUGH IT IS NOT ANYWHERE COMPLETELY EXPOSED. ARGILLIZ-ED OLIVE TUFFACEOUS SEDIMENTS ARE ADJACENT TO THE OPALITE. THE- OPALITE UNDERLIES A RIDGE-CAPPING TERTIARY BASALT FLOW UNIT. -ORE IS PRESUMABLY AT THE SAME STRATIGRAPHIC HORIZON AS THAT AT- THE GOLDBANKS MINE, AND IT HAS THE SAME GENERAL CHARACTER WIT-H FINELY DIVIDED CINNABAR COLORING FAVORABLE PARTS OF THE OPAL-ITE BLANKET. LOCALLY THE OPALITE IS UNUSUALLY VUGGY WITH IRREG-ULAR CAVITIES LINED WITH CLEAR CRYSTALS OF POST-CINNABAR QUART-Z. ORE LACKS CONTINUITY.
Comment (Workings): MANY BULLDOZER CUTS, SHORT ADITS, SCATTERED PITS, SMALL OPEN PIT, DRILL HOLES.
Comment (Development): R-ESTAKED BY OTHERS (POSSIBLY KENNECOTT?). IN 1984, RECENT ROTAR-Y DRILLING AND ROADS NORTH OF THE OLD PIT 200+ M WERE NOTED, P-OSSIBLY BY KENNECOTT.
Comment (Development): IN 1940, THE PRONTO PLATA CLAIMS 1-9 AND THE RED HILL CLAIM WERE LOCATED, AND LATER ABOUT 50 MORE PRONTO PLATA CLA-IMS WERE ADDED. IN 1942 AND 1943, THE BRADLEY MINING COMPANY D-ID CONSIDERABLE EXPLORATION BY MEANS OF ABOUT 20 BULLDOZER CUT-S, SHORT ADITS, AND SCATTERED PITS OVER ABOUT 0.5 SQ MI. THE L-ARGEST CUTS ARE BELOW THE SMALL CABIN ON THE PROPERTY AND CONS-IST OF A 400-FT-LONG GASH ALONG THE HILLSIDE, AND 2 OTHER CUTS- ABOUT 140 FT LONG, DIVERGING FROM IT AND TRENDING AT RIGHT AN-GLES UP THE HILL. IN SPITE OF EXTENSIVE EXPLORATION, THE ONLY -PRODUCTION HAS COME FROM TEST RUNS OF ORE HAULED TO THE BRADLE-Y FURNACE AT OPALITE, AND BY AUG 1943, THE PROPERTY WAS IDLE. -TITLE TO THE PROPERTY WAS RETAINED BY H. W. BALDWIN UNTIL 1962- WITH ADDITIONAL EXPLORATION DONE UNDER LEASE BY STANLEY JOHNS-ON IN 1958, COLGATE CORP OF LOS ANGELES IN 1959, AND C. R. BIS-HOP AND T. R. MOXNESS IN 1961, BUT NONE OF THESE ACHIEVED ANY -PRODUCTION. BALDWIN DROPPED THE PROPERTY IN 1962, AND IT WAS
