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 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 (Deposit): REYNOLDS OWNS APPROXIMATELY 75 PERCENT OF THE RESOURCE AREA, WATER AND ELECTRICAL POWER ARE ALREADY ESTABLISHED AT THE MINE SITE. ADDITIONAL MAPS ARE ST. HELENS, CHAPMAN, TRENHOLM, TAINERS, CLATSKANI. THE AREA WAS AUGERED AND CORE DRILLED FROM 1945 TO 1970. THERE IS MINOR DEFORMATION BECAUSE OF LATERIZATION. MOST OF THE LATERIZATION TAKES PLACE ON THE LOWER PART OF THE DIP-SLOPE. TO SOME EXTENT THE LAND FORMS ARE A RESULT OF DEFORMATION AND THE ORE IS RELATED TO GEOMORPHOLOGY. ORE IS NOT CONTINUOUS FOR THE LENGTH AND WIDTH OF THE MINERALIZED ZONE. MATRIX GRADES AND TONNAGES ARE BASED ON WET TONNES. BAYER PLANT COSTS ARE THE BASIS FOR BENEFICIATION COST ANALYSIS.
