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, electrum

Comment (Economic Factors): There was unknown but small amount of historic production from the mine in the 1930s.In 1998, reserves were reported to be 130,000 to 140,000 oz Au proven, plus 300,000 oz Au indicated.

Comment (Geology): The shear zone contains small amounts of gold and silver in gangue of quartz and iron oxides.

Comment (Identification): The current record incorporates material from MRDS record # M030034 for the old Winnemucca Mountain Mine which is encompassed by the current Winnemucca Gold Property.

Comment (Location): The property is located on the southern slope of Winnemuca Mountain.

Comment (Workings): The historic mine was developed by a series of open cuts and shallow tunnels

Comment (Commodity): Gangue Materials: quartz; iron oxides; molybdenite, chalcopyrite

Comment (Deposit): The property is covered by 22 or more unpatented claims.

Comment (Development): The historic Winnemucca Mountain mine was owned by Gus and Ab Rogers from at least 1937 through 1945. The ore shipped from the mine during this period had a high iron content, and was shipped primarily for use as flux. The mine area has been prospected sporadically since that time as a precious metals prospect. In 1997, Anvil Resources announced delay of a two-phase drilling program scheduled for the Winnemucca Mountain gold property while it sought additional funding or a joint venture partner. Extensive earlier exploration on the property proved up 130,000 to 140,000 oz of gold in the main stockwork zone with several other potential zones targeted for drill testing. In 1987 in the same area, Pallaum Minerals announced signing of an option to acquire what they called the ?W property? , where earlier drilling identified disseminated gold in silicified sediments and in quartz/ carbonate veining (Pallaum Minerals press release, 4/16/97). In 1998, Pallaum began a preliminary exploration program on the property and planned drilling in the latter part of the year. The work centered on an area of gold mineralization that graded 0.04 opt gold over 100 feet. Pallaum Minerals was subsequently evaluating potential joint venture opportunities.
