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.

Comments
Comment (Location): DESCRIPTION NOT ENTIRELY CLEAR BUT THE IRONTON GROUP CONSISTED OF FIVE CLAIMS STAKED ALONG THE SHORELINE OF UPPER HALF OF TOWER ARM, PROBABLY ON THE WEST SHORE (ROEHM, 1946 [IR 195-41]). LOCATION KNOWN ONLY TO WITHIN TWO MILES OF SHORELINE BUT LIKELY TO BE IN SECTION 19 OR 30, T. 58 S., R. 76 E.
Comment (Deposit): ROEHM (1945 [IR 195-41]) DESCRIBES THE PROSPECTS AS A ZONE OF MINERALIZED SCHIST THAT OUTCROPS AT HIGH TIDE. PYRITE IS DISSEMINATED AND IN NARROW THIN SEAMS IN THE SCHIST. SMALL SPECKS OF SPHALERITE AND GALENA OCCUR IN SOME OF THE THICKER SEAMS. RECENT GEOLOGIC MAPPING (SUE KARL, ORAL COMMUNICATION, 1998) INDICATES THAT THE ROCKS ON THE WEST SIDE OF TOWER ARM DEFINITELY INCLUDE DEVONIAN SCHISTS AND MAY INCLUDE SOME OF THE TRIASSIC HYD GROUP THAT HOSTS VOLCANOGENIC MASSIVE-SULFIDE DEPOSITS IN THE REGION.
Comment (Workings): AN OLD OBSCURE PROSPECT THAT HAS HARDLY BEEN MENTIONED IN A HALF CENTURY. HOWEVER, THE AREA IS PROBABLY PRESENTLY UNDER CLAIM IN ONE OF THE LARGE CLAIM BLOCKS THAT HAVE STAKED IN THE VICINITY IN THE LAST SEVERAL YEARS AS A RESULT OF RENEWED INTEREST IN THE DUNCAN CANAL AREA.
Comment (Production): NONE
Comment (Exploration): Status = Active
