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.

Comment (Development): INTERMITTANT SMALL-SCALE MINING OR PROSPECTING BETWEEN 1908 AND 1932 REPORTED. MINING BY OPEN-CUT METHODS. EXPLORED BY SEVERAL PROSPECT PITS AND DRILL HOLES.

Comment (Deposit): GOLD AND CASSITERITE IN BASAL PART OF MAINLY UNFROZEN CREEK AND BENCH GRAVELS AND IN THE TOP FEW FEET OF BEDROCK. JUST BELOW THE MOUTH OF HENDERSON CREEK PLACERS APPEARED TO HAVE BEEN LIMITED TO THE PRESENT CREEK GRAVEL DEPOSITS, ALTHOUGH SOME BENCH GRAVELS PROBABLY WERE MINED. GOLD BEARING GRAVELS AT AN UNKNOWN SITE ABOUT 5 FEET THICK. GROUND SAID TO AVERAGE 12 TO 20 FEET IN DEPTH; INCLUDES BOTH MUCK OVERBURDEN AND GRAVEL.

Comment (Workings): MOST OF BENCH GROUND IS UNFROZEN AND ALL OF THE GRAVEL IN THE VALLEY BOTTOM IS UNFROZEN AND WET.
