Pacific Matchless Mine

The Pacific Matchless Mine is a silver and lead mine located in Pershing county, Nevada at an elevation of 6,001 feet.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

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.

Comment (Deposit): TWO ADITS EXPLORE THE MINERALIZED SHEAR ZONE WITH SOME STOPING AND DRIFTING AT THE END OF EACH ADIT. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT

Comment (Geology): GEOL.COM: LARGE CUBES OF PYRITE OCCUR BOTH IN QUARTZ-TOURMALINE VEINS AND WALL ROCKS. BASALT FEEDER DIKES, YOUNGER THAN THE MINERALIZATION, WERE FOUND LESS THAN 5 CM THICK IN DRIFTS OF THE LOWER ADIT. PROBABLY RELATED TO THE LATE TERTIARY BASALT FLOWS CAPPING LIMESTONE RIDGES IN EASTERN PART OF THE DISTRICT.
