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.
Mine Description
The Fravel mines, including the Golden Fleece mine, are located at the abandoned camp of Poeville in secs. 13 and 24, T. 20 N., R. 18 E. The mineralization occurs in schistose metavolcanics cut by dikes of quartz monzonite porphyry of Tertiary age. The rocks are bleached in the zone of weathering and grade downward into greenish propylitized rocks containing abundant pyrite. The trend of the foliation in the meta volcanics ranges from about N. 30° E. to about N. 70° E. with a near vertical dip.
The economic metallic mineralization occurs in quartz-calcite stringers or veinlets, which contain abundant pyrite and varying amounts of enargite, galena, sphalerite and argentite. These veinlets are concentrated in lodes or stockwork-like bodies of unknown dimensions which, in general, parallel the foliation of the metamorphic rocks.
Hill (1915, p. 193) states that the ore in general was low grade, ranging between $4.60 and $12.00 per ton in gold and silver. Some pockets of high grade gold-silver ore were mined in the oxidized zone, and small bunches of rich silver-copper are have been mined in the sulfide zone.
The workings in the Poeville area consist of several shafts and tunnels and numerous pits and trenches. The main shaft at the Fravel-Paymaster mine is reportedly 400 feet deep and includes 2,000 feet of lateral workings (Overton, 1947, p. 76). Most of the workings are now inaccessible. None of the shafts can be entered.

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 (Workings): MINERALIZATION OCCURS IN SCHISTOSE METAVOLCANICS CUT BY DIKES OF QUARTZ MONZONITE PORPHYRY. ROCKS ARE BLEACHED IN WEATHERED ZONE, GRADE DOWN INTO GREENISH PROPYLITIZED ROCKS CONTAINING ABUNDANT PYRITE. TREND OF FOLIATION IN METAVOLCANICS RANGES FROM N30E TO N70E, WITH NEAR VERTICAL DIP. ECONOMIC MINERALIZATION OCCURS IN QUARTZ-CALCITE STRINGERS WHICH PARALLEL THE FOLIATION IN THE METAVOLCANICS. VEINLETS ARE CONCENTRATED INTO LODES OR STOCKWORK-LIKE BODIES.

Nevada Gold
Nevada has a total of 368 distinct gold districts. Of the of those, just 36 are major producers with production and/or reserves of over 1,000,000 ounces, 49 have production and/or reserves of over 100,000 ounces, with the rest having less than 100,000 ounces. Read more: Gold Districts of Nevada.
