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 (Geology): A FINE-GRAINED GRANITIC INTRUSIVE IN CONTACT WITH INTERBEDDED LIMESTONE & MARBLE WITH THE STRIKE OF THIS CONTACT GENERALLY S70E AND N70W, WITH DIP STEEP TO THE SOUTH. A LARGE THRUST FAULT BLOCK OF THE GRANITIC ROCK CRUSHED THE ONE TIME LIMESTONE BEDS MAKING THEM CHANNELS FOR THE TRANSPORTATION AND DEPOSITION OF SILICA AND TUNGSTEN BEARING SOLUTIONS ORIGINATING FROM THE GRANITIC INTRUSION. THIS DEPOSIT IS RELATED TO THE ADJACENT NEVADA SCHEELITE ORE BODY, AND MAY BE PART OF ROOF PENDANT PLUNGING NORTH.
Comment (Development): CONSISTING OF 4 UNPATENTED LODE CLAIMS. PROPERTY WAS PREVIOUSLY OWNED AND WORKED BY THE DON CLARE MINING CO. IN 1955 AN INVESTMENT GROUP HEADED BY CLARENCE THORNE REOPENED THE MINE TO THE 100-FT. LEVE. LAST ACTIVITY AT THORNE MINE WAS IN 1976 WHEN THE OPEN PIT AREA WAS STRIPPED AND CLEARED TO THE ORE ZONE
Comment (Deposit): STRATA OF SCHEELITE-BEARING TACTITE OCCURS AS CRUSHED IRON OXIDE-STAINED LAYERS OF FROM 1 1/2' TO 5 FEET THICK AND 12-30 FT. LONG. THESE OCCUR AS FAULTED SEGMENTS SANDWICHED IN BETWEEN STRATA OF MARBLEIZED LIMESTONE.
Comment (Workings): VERTICAL SHAFT TO 100 FT. LEVEL WITH 200 FEET OF DRIFT AND STOPES TO THE SURFACE; INCLINE SHAFT 100 FEET WITH 100 FOOT OF DRIFT.
Comment (Production): MOST OF PRODUCTION DURING WORLD WAR I
