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: Private
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 (Location): NEAR THE HEADWATERS OF THE WEST FORK OF PILGRIM CREEK

Comment (Deposit): VEINS ARE STRICTLY FRACTURE FILLINGS WITH NO SIGN OF REPLACEMENT. VEINS ARE UNIQUE IN THAT THERE IS NO NOTICEABLE WALL ROCK ALTERATION. VEIN WIDTHS RANGE FROM 1 TO 15 INCHES, BUT THE SMALLER VEINS ARE USUALLY GROUPED IN PARALLEL CLUSTERS SO THAT THE TOTAL OR ACCUMULATED VEIN WIDTH AT ANYONE POINT IS RARELY LESS THAN 6 INCHES.

Comment (Workings): WORKINGS CONSIST OF TWO ADITS APPROXIMATELY 300 AND 850 FT LONG RESPECTIVELY.

Comment (Geology): HOST BEDS STRIKE N 25 DEG TO 45 DEG W AND DIP 9 DEG TO 25 DEG NE. QUARTZ AND PYRITE WERE THE FIRST TO MINERALIZE. SPHALERITE AND CHALCOPYRITE WERE PROBABLY DEPOSITED SIMULTANEOUSLY BECAUSE MOST SPHALERITE CONTAINS MINUTE EXSOLUTION BLEBS OF CHALCOPYRITE ALONG CRYSTAL PLANES. MOST CHALCOPYRITE, HOWEVER FORMS RELATIVELY LARGE MASSES. ALL MINERALS WITH THE EXCEPTION OF PYRITE AND MARCASITE OCCUR THROUGHOUT THE VEIN AS BLEBS AND MASSES WITH RELATIVELY LITTLE INTERMINGLING OF SPECIES.

Comment (Development): SEVEN UNPATENTED CLAIMS. ORIGINAL DEVELOPMENT WORK WAS BY SURFACE PITS. MINE WAS INACTIVE FROM 1950 - 56 . IN 1957 MINE WAS REOPENED BY HOLLIDAY MINES AND WAS DEVELOPED INTERMITTENTLY THROUGH 1971 .

Principal Gold Districts of Montana

In Montana, 54 mining districts have each have produced more than 10,000 ounces of gold. The largest producers are Butte, Helena, Marysville, and Virginia City, each having produced more than one million ounces. Twenty seven other districts are each credited with between 100,000 and one million ounces of gold production. Read more: Principal Gold Districts of Montana.
