Hercules Property

The Hercules Property is a gold and silver mine located in Lyon county, Nevada at an elevation of 6,266 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.

Land Status

Land ownership: BLM Administrative Area
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 (Commodity): Ore Materials: gold

Comment (Commodity): Gangue Materials: pyrite

Comment (Deposit): Hercules hosts epithermal gold and silver mineralization within two separate northerly-trending structures. Mineralization is associated with a shear zone, dipping 80-85E. The vein dips 5-10E and is greater than or equal to 20 feet thickT. he host structures, each approximately 9,000 feet in length, remain open along strike and down dip. Workings follow a shear dipping 80-85E in host andesite flow containing andesite boulders up to 2 feet in diameter . One adit also cut a 20-foot thick vein trending N5-10E that was hydrothermally altered, light tan, mostly brecciated and commonly containing fine-grained pyrite.

Comment (Workings): The old workings consist of three adits, two shafts and approximately ten prospect pits, in an area of new roads, drill pads and many major drill holes dating from about 1980 to the present time (1989). Above the old workings several drill pads were used to slant drill at vein system from the southeast. Two crosscut adits trend S80E.

Comment (Development): In September, 1997, Adamas Resources Corp. announced that it had entered into an agreement with GLS Global Assets Ltd. whereby GLS can acquire a 51% interest in Adamas' Hercules gold project. More than $2 million in exploration work has been done since 1984 on the property including over 34,000 feet of core and RVC drilling by prior earlier optionees, including Asamera, Horizon Gold, St. Joe Minerals and Phelps Dodge. Under the terms of the agreement, GLS would have until December 31, 1997 to complete a due diligence evaluation of the Project. Adamas planned to conduct its own exploration work on the Project, focusing on the numerous as-yet untested gold anomalies and geophysical targets previously identified on the Project grounds. In 1989 the property was owned by Ivan Bowman, 105 Bardie Court, Grass Valley, California. In 2004, Three reverse circulation holes drilled by Lincoln Gold Corp. to test the deeper levels of the Hercules vein system in the Como district failed to find bonanza-grade gold and silver mineralization. The holes encountered intervals of low-grade gold values near the surface, but the bonanza-grade values were not present at depth. Miranda Gold Corp. and Lincoln therefore terminated their joint venture and option on the Hercules property.

Comment (Economic Factors): In 1996, reserves for the property were reported at 7,313,000 tons of ore grading 0.023 opt gold and 0.159 opt silver,an a total geologic resource of 20-50 million tons grading 0.040-0.045 opt gold. In 1997, Adamas reported that the property contained a geological resource amenable to open pit mining methods estimated at between 170,000 and 213,000 ounces of gold with over 1.5 million ounces of silver.

Comment (Geology): NBMG samples 3767 and 3768 were taken in the workings.

Comment (Identification): This record supersedes earlier records #RE00005 and MP90063 from which all material has been incorporated into the current record. Records #RE00005 and MP90063 should be deleted.

Comment (Location): The Hercules Property is at Barton Springs on the north slope of the Pine Nut Mountains, about 4 miles north of the major Como District mines.
