The Cuprite Mine is a documented Gold, Silver and Copper mine in the keystone mining district of Grant County, Wyoming.
Featuring historical workings from the year 1900 including a 954’ drift tunnel, a connecting 165’ incline shaft, a concrete braced tunnel-way, small creek and lakeside frontage.
The Keystone district surrounds the village of Keystone adjacent to Douglas Creek in the Medicine Bow Mountains, and is considered to include all lode deposits adjacent to and within the Keystone quartz diorite .
Ore minerals include malachite, azurite, cuprite, native copper, and native gold in the supergene zone. The underlying hypogene minerals include chalcopyrite, bornite, pyrite, native Copper, and native Gold.
In recent years (1983), some rich samples of gold-bearing quartz diorite have been found near Keystone.
One of the less spectacular samples containing visible gold assayed 18 oz./ton Au.
Primary workings consist of an inclined shaft 165’ deep driven at a 15 degree angle into the mineralized ore trend of the Albany Vein. Shaft workings are located on the upper hillside above the adit workings.
A connecting drift 954’ in length was driven and developed at a 90 degree angle to serve as a haulage adit.
The adit tunnel was constructed with large concrete and timber supports during a previous operation in the 1960’s.
The vein assayed 3 to 28% copper, a trace to 2.56 oz. per ton of gold, and a trace to 2 oz. of silver per ton. cobalt and chromium were also reported
A significantly sized mine spill emanates from the main adit portal, to nearly 600 feet in length and 6 feet in depth. estimated at well over 300,000 yards in material, the mine spill is comprised of granite/ feldspar host rock and low to mid grade ores.
Adit portal and shaft collar have eroded closed over nearly two decades of neglect.
Underground workings require minor rehabilitation and removal of overburden to continue exploration and sampling.
Placer gold values can be mined from the small creek running from the northern hillside through the property to the mouth of Moores gulch.
The small spring-fed creek features moderate water flow with a depth of 2"-to-7" and a width of 2'-to-3.5'.
Suitable for a small river sluice or high-banking operation.
Free gold values have been located in the primary mine spill during the initial survey as well.
Access to the secluded area is excellent via maintained dirt roads, with easy access for any mid clearance vehicle or camper.
Dual parking and staging areas are available near the lakeside, and the northern creek runoff.
Roads are accessible from May to November by motor-vehicles and by snowmobile only during winter months.
Mineral property encompasses the beaches of Rob Roy reservoir, famous for excellent fishing and Kokanee Salmon.
This one on a kind Gold mine holds excellent potential for continued work on the existing and unknown mineral deposits of the property.
The district has been said to hold potential for undiscovered world class deposits.
An excellent property for the beginning enthusiast up to an established mining company.
