Gold Rush Expeditions, Inc. is proud to present the Historic Keystone Mine Property. The Keystone Mine is a grouping of 80 acres of lode mining claims. These mines have historically been worked for Gold and silver in quantity. The Keystone Mine is for sale exclusively through Gold Rush Expeditions, Inc. The Keystone claims are located just outside of Winnemucca, Nevada and have been properly staked and marked at all corners.
All Gold Rush Expeditions, Inc. claims are meticulously surveyed, mapped and researched. On-site field work is completed by Corey Shuman and Jessica Shuman, nationally recognized Mineral Surveyors with over 36 years of combined experience.
Somewhat remote, but very historic gold mining area. The area is known for gold recovery in washes and alluvial plains. The gold deposits, while known, are not widely mapped And the extent is largely unknown but favorably reported by development geologists. The Keystone mine provides excellent value for a small to medium sized commercial operation. Commercial is recommended as there will be some investment required in permitting and clearing the shafts and adits for safe working.
There is extensive tonnage in gold and silver reserves noted in 1940s US Bureau of Mines and Geology reports. The extent and depth of the deposits are not mapped or defined but described as likely very large. Large enough to support the proposed development of a small town to house the miners in 1942.
A series of 4 lode claims covering the actual workings and outcrops of the historical Keystone Mines and the Tamzy Claims.
The Keystone Mine site could be broken down into two camps, east, and west. The West Keystone Mine Camp has been known as the Keystone #4 and 5 and the Tamzy #3. These workings are accessible when dry, but will require some pumping and clearing work. In the spring season, the adit contained 3' of water making it largely inaccessible. The shaft above is in good condition but the exposed timber work has started to collapse and will need to be cleared. There are many open trenches and exposed ore bodies that have been sampled as recently as 1981. Gold is the primary element that has been worked in the mines but there are also reported deposits of silver and platinum.
The eastern Keystone Mine camp covers the historic Keystone Mine, Keystone Mine 2-5, and the North Keystone Mine. These mines are the primary workings as reported in historical reports. The mines are easily accessible. Surveyors documented thousands of tons of ore have been blocked out underground in the smaller workings. Air shafts from upper adit can also be used as escape routes which are required for commercial operations. Surveyors observed a wide gold and silver lode in the mine that has been sampled and lightly worked. Vein gets as wide as 3 feet in some areas and pinches into the size of a thread in others. Ore is dark, heavy with lead and silver and has some visible gold flake in it. Lode and veins are still intact and should be explored and worked further.
Access to the Keystone Mine is direct and simple. Getting trailers or equipment to the site on the current roads will not be an issue. No need to improve roads for machinery. Impressive amount of ore carloads were removed from the upper adits lower level (not surveyed) as evidenced by the carbide ore car markings inside the mine. Headframes would need to be stabilized before use.
History of the Keystone Mine
The Keystone was developed on a small scale in or around 1870, minimal investment was expended and minimal amounts of gold and silver were shipped from the mine. The mine produced in small quantities until 1936 when the “Jones Bros.” leased the property from the Jackson family. From 1936 to 1940, the Jones bros did much sampling of the existing workings and dumps. Additionally, substantial geological survey and reporting in preparation for development of the property into a full scale producing property. This effort and expenditure were thwarted by the War Act in 1941. A full reporting was released in 1942 which detailed the high potential of a very profitable operation and very rich mine. The mine was never developed further after the War Act was rescinded. The property was retained by the Jones (Jones Bros. from above) until 1989 when the Carl Family (related by marriage to the Jones) took over the claims. These claims lapsed due to non-payment in 2012.
From a USBM report: The Keystone Mine was first located by Phillip Muller in 1872 and later acquired by Mrs. Bertha Jackson. In 1936 it was leased to R. M. and A. H. Jones of Winnemucca. The Nevada Keystone Co. was organized in 1942 which leased the property to the Dayton Dredging Co. of San Francisco, California.
An assay report from 1940:
Our sample No. 227 had a width of 5 feet and showed: gold .02 oz, silver 17.9 oz, lead 2.9% and zinc 2%. The drift was started in this ore. A car sample from the first round in the drift, representing 9 tons hoisted, gave: gold, .05 oz; silver, 13.05 oz; lead, .9%; zinc, 1.4%.
Extensive mappings and current and historical reports match up well and show the potential and established values in the mine and around the mine.
