Notice Regarding Unpatented Mining Claims for Sale


Unpatented Mining Claims


Unpatented mining claims are claims in which the claim holder owns the mineral rights to the property but not the surface land. The surface belongs to the U.S. government and is administered by the Bureau of Land Management (BLM) and/or the U.S. Forest Service. Surface access  for the mineral rights owner is gauranteed under the 1872 mining law but rules and regulations do apply.  The county in which the claim is located maintains claim records of unpatented mining claims as required by law and collects a fee for this service. Claim requirements very by state a complete list of state and federal laws and regulations is available on our website by clicking the button below.

Mining Potential


Unique opportunity for both a small-scale underground mine and the discovery and development of 100-million-ounce silver equivalent ore body.   

Small scale mining possible of 17,500 tons of ore containing 188,475 ounces of Silver and 1557 ounces of Gold.  

At $15 silver and $1400 gold gross metal value is $7,457,625 with substantial potential to develop reserves many-fold.

Revett Formation

Unique Silver & Gold Occurrence in the Revett Formation of the Belt Rocks.   

The Revett formation is the primary source of production in the nearby Coeur d’ Alene Mining District which has produced over One Billion ounces of silver.

The Granite Peak Cobalt-Copper-Nickel-Gold Property Available

North Idaho Polymettalic Prospect

Cobalt Mining Claims

The property is located in North  Idaho. Sampling revealed mineralized zones with as much as 2.3% Copper, .21 % Cobalt, .38% Nickel, and .06 oz. per ton Gold.  



The dominant rock types are fine to coarse-grained, garnet-bearing muscovite schist on the ridge top, underlain by thin-bedded siltstone/quartzite. Both foliation in the schist and bedding in the siltstone/quartzite strike northeasterly and dip at low angles to the northwest. Crosscutting these structures is a steeply- to vertically-dipping shear zone containing pockets of massive sulfides (pyrrhotite, and very small amounts of chalcopyrite and pentlandite). The zone contains massive carbonates (calcite and siderite/ankerite), large green trelolite crystals, and minor quartz, talc, sericite, chlorite, magnetite, and biotite. Cobalt and nickel are associated with the pyrrhotite. At the surface, these minerals are in a red-orange iron oxide zone (pictured above). Also, present are subparallel massive quartz veins that are up to 10 ft thick, strike N. 65" W., and dip near vertical.

Exploration of the area has proved that copper, cobalt, nickel, and gold bearing minerals are present. The prospect is to early stage to identify economic deposits, although it appears to have high potential. The most likely deposit-model types will be vein or stratabound, possibly fitting Blackbird-type cobalt-copper model. The presence of rocks and mineralization similar to that in the Idaho cobalt belt indicates that the belt may extend  much farther north than previously thought. Both the subject property and an unnamed prospect in a nearby drainage contain significant amounts of cobalt associated with pyrite and other sulfides. This should result in exploration beyond the bounds of the presently  identified Idaho cobalt  belt area.


The property is currently available for purchase, joint venture or earn-in agreement with qualified exploration and mining companies. Interested parties should be prepared to sign a confidentiality and area of interest agreement. Inspection of data and site visit can be arranged after documents are signed by both parties. Seller makes no representations either expressed or implied. All interested parties should conduct due diligence efforts by a qualified registered professional geologist. Contact Kurt J. Hoffman at 208-661-7517.
