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): THE COUNTRY ROCK IS GRANITE WITH INTRUSIVE DIKES. COPPER ORE APPEARS IN AND NEAR THE CONTACT OF TWO OF THESE DIKES AND FOR OVER A HUNDRED FEET FROM THE CONTACT. THE SILICIOUS AND BASIC INTRUSIVE ROCKS ARE COVERED IN PLACES BY LIMESTONE WHICH WAS PROBABLY THE INTRUDED ROCK AND ONLY LIES ON AND NEAR THE SURFACE. THE DIKES STRIKE A LITTLE NORTH OF WEST AND DIP SOUTH 60 DEGREES. COPPER OF VARIOUS VALUES IS FOUND ALONG THE CONTACT FOR OVER TWELVE HUNDRED FEET. THE IDAHO EXTENSION SHAFT HIT ORE ABOUT 8 FT. WIDE WITH CU-SULFIDES AND-OXIDES RUNNING 10% CU. THE ROSS SHAFT IS LOCATED ON OUTCROP OF AZURITE WHICH DIPPED OUT OF SHAFT 15 FEET, THIS ORE GAVE BETTER THAN 18% CU. ON ABE LINCOLN EXTENSION CLAIM HEMATITE AND LIMONITE CARRIES GOLD VALUES.
