The Guanomi Mine is a molybdenum mine located in Washoe county, Nevada at an elevation of 3,940 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.

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 (Location): ON SW SHORE PYRAMID LAKE
Comment (Workings): ORIGINALLY PROSPECTED IN 1920'S AS A AU-AG PROSPECT, WAS EXPLORED IN THE 1930'S AND AGAIN IN 1971-72 AS A MO-CU PROSPECT. OUTCROP AREA COVERS ONLY FEW HUNDRED SQUARE YARDS, IS SURROUNDED BY LAKE LAHONTAN SEDIMENTS. LARGER OUTCROP OF ALTERED QUARTZ MONZONITE PORPHYRY OCCURS TO SOUTHWEST, ON RIDGE ON EAST SIDE OF TOM ANDERSON CANYON.
Comment (Geology): QUARTZ MONZONITE PORPHYRY INTRUDES ASH FLOW TUFFS OF HARTFORD HILL RHYOLITE THIN OXIDE ZONE CAPS PRIMARY SULFIDES. ALTERATION AND MINERALIZATION PRESENT IN THE QUARTZ MONZONITE STOCK SUGGESTS THE POSSIBILITY OF A COMMERCIAL BODY OF MOLY ORE.
