Goat Rocks

The Goat Rocks is a copper and molybdenum mine located in Lewis county, Washington at an elevation of 6,201 feet.

About the MRDS Data:

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: National Wilderness
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 (Development): PRONOUNCED MAGNETIC LOW AND GEOCHEMICAL ANOMALIES. GLACIER LODE CLAIM APPEARS LONG ABANDONED

Comment (Deposit): TWO OTHER AREAS WITHIN THE GOAT ROCKS STUDY AREA HAVE POSSIBLE PORPHYRY COPPER-RELATED MINERALIZATION BUT ARE DEEMED LESS FAVORABLE THAN THE GOAT ROCKS AREA. ; INFO.SRC : 1 PUB LIT

Comment (Reserve-Resource): AREA IS DETERMINED TO HAVE A MODERATE POTENTIAL FOR PORPHYRY COPPER TYPE MINERALIZATION

Comment (Commodity): ELEMENTS LISTED ARE GEOCHEMICALLY ANOMALOUS IN SAMPLES COLLECTED FROM THE MINERALIZED AREA

Comment (Location): UNSURVEYED. AREA IS JUST NORTH OF OLD SNOWY MOUNTAIN BENEATH AND WEST OF THE PACKWOOD GLACIER. LOCATION GIVEN IS FOR GLACIER LODE CLAIM

Comment (Geology): AREA HAS PRONOUNCED COLOR ANOMALY DUE TO OXIDATION OF PYRITE
