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.

Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments
Comment (Deposit): VEINS-SERIES OF AT LEAST 3 VEINS OF COPPER SULFIDE AND OXIDE MINERALSA 50-CM WIDE TECTONIC CRUSH ZONE LIES ALONGS A N20E, 50SE FAULT IN GREENISH CALCAREOUS HORNFELS AND PHYLLITE AND P-OSSIBLY GREENSTONE OF ORDOVICIAN VALMY FM. QUARTZ VEIN MATTER - WITH LESSER CALCITE (PARTLY LATER THAN QUARTZ) IN THE ZONE CO-NTAINS PYRITE, CHALCOPYRITE, AND LIMONITE, MALACHITE AND RARE -AZURITE. THE QUARTZ VEIN MATTER IS MILKY WITH LOCAL COCKADE ST-RUCTURE. A PROSPECT PIT ON RIDGE 200 M EAST OF MINE IS SIMILAR-, BUT CONTAINS MORE LIMONITE GOSSAN IN QUARTZ VEIN MATTER ALON-G A N-TRENDING 45 DEGREE EAST FAULT CRUSH ZONE UP TO 2 M WIDE.- TAN TO PINK CALCITE OCCURS AS GANGUE AND IS PARAGENETICALLY L-ATER THAN QUARTZ.
Comment (Geology): OXIDIZED AND SULFIDE COPPER MINERALS OCCUR IN A SERIES OF AT LEAST THREE VEINS FROM 4 TO 7 FEET WIDE WITH A GENERAL NORTH AND SOUTH STRIKE AND DIPPING FROM 50 TO 80 DEGREES EAST. THE GANGUE IS PRINCIPALLY QUARTZ, CALCITE, AND COUNTRY ROCK.
