The Madeline Claim is a manganese and iron mine located in Clallam county, Washington at an elevation of 1,686 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.

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.

Comments

Comment (Location): ABOUT 1 MI NORTH OF US 101; 1 MI WEST OF HECKLES, ALONG A ROAD IN BAD CONDITION TO BEAR CAT CLAIM, THEN BY TRAIL 0.25 MI.

Comment (Deposit): MANGANESE SILICATES IN RED LIMESTONE STRIKE EAST AND DIP ABOUT 65 N. THE FOOTWALL IS MARKED BY A STRONG SHEAR ZONE. THE RED LIMESTONE IS BORDERED ON THE NORTH BY A NARROW BAND OF TUFF AND ON THE SOUTH BY PILLOW BASALT. IN THE WESTERNMOST PIT THE BUREAU OF MINES IN 1939-40 SANK A 7- BY 7- FT INCLINED SHAFT 80 FT IN THE SHEAR ZONE ALONG THE FOOTWALL OF THE MINERALIZED BODY. IN THE SHAFT MANGANIFEROUS LIMESTONE AND SILICA CAN BE SEEN ALL ALONG THE HANGING WALL. BETWEEN DEPTHS OF 30 AND 55 FT, PILLOW BASALT IS ALSO SEEN IN THE HANGING WALL. THE FOOTWALL OF THE INCLINED SHAFT IS COMPOSED OF BASALT IN THE UPPER PART; SILICA IN THE MIDDLE PART; AND A RED ROCK CONTAINING SILICA, IRON, AND MANGANESE IN THE LOWER PART. AT A DEPTH OF 37 FT A CROSSCUT WAS DRIVEN 24 FT NORTHEASTERLY THROUGH LIMESTONE AND MANGANESE SILICATES TO A CONTACT WITH A SHEARED RED LIMESTONE AND SILICA. A ZONE OF MANGANESE SILICATES 15-20 FT THICK WAS PENETRATED BY THE CROSSCUT. FROM THE SAME STATION, 37 FT BELOW THE

Comment (Workings): THREE TRENCHES; ONE 80 FT SHAFT; ONE 37 FT CROSSCUT; ONE 8.5 FT DRIFT; ONE 25 FT ADIT. THREE TRENCHES SPACED 10 FT APART, AVERAGING 25 FT LONG, 8 FT WIDE, AND 10 FT DEEP, WERE CUT IN THE PILLOW BASALT. THESE CUTS EXPOSE MANGANIFEROUS MATERIAL ASSOCIATED WITH SILICA AND A STRONG SHEAR ZONE THAT IS ELSEWHERE COVERED WITH OVERBURDEN. A25-FOOT ADIT 27 FT WEST OF THE INCLINED SHAFT IS CAVED. THIS ADIT IS REPORTED TO HAVE BEEN DRIVEN IN THE PILLOW BASALT AND TO HAVE ENCOUNTERED MANGANESE SILICATE 11-18 FT FROM THE PORTAL.

Comment (Deposit): COLLAR, A DRIFT WAS DRIVEN 8.5 FT EASTWARD ALONG THE SOUTHERN CONTACT OF THE MINERALIZED ZONE TO DETERMINE THE DIRECTION OF THE CONTACT. THIS CONTACT CONVERGED ON THE ONE PREVIOUSLY FOUND IN THE FACE OF THE CROSSCUT.
