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 (Workings): POSSIBLE GROUND SUBSIDENCE BENEATH A RESIDENTIAL AREA FROM SUBLEVEL CAVE OPERATIONS WOULD BE THE MOST SERIOUS ENVIRONMENTAL CONCERN.

Comment (Production): PRODUCTS LISTED ARE FOR THE OVERALL OPERATION AND NOT JUST THE ANSELMO.

Comment (Economic Factors): THE PRODUCTION ZINC-LEAD RATIO OF 5.75 TO 1 (MILLER,1973).

Comment (Deposit): THE ANACONDA COMPANY HAS NO PRESENT PLANS TO RESUME ZINC MINING BUT THE SYNDICATE VEIN RESOURCES AND THE NEAR SURFACE RESOURCES AROUND THE ALICE PIT ARE BEING REEVALUATED BECAUSE OF RECENT SILVER AND ZINC PRICE INCREASES. THIS EVALUATION INCLUDES FIVE BUTTE ZINC MINES WHICH HAVE THE LARGEST POTENTIALLY MINEABLE REMAINING RESOURCES. THE EVALUATION INCLUDES THE ALICE ANSELMO BADGER, LEXINGTON, AND MOUNTAIN CON. MINES. 1985 UPDATE. NO ACTIVITY AT MINE SINCE 1981.

Comment (Geology): NARROW VEIN WIDTHS AND LENGTHS ARE AVERAGES OF MANY BLOCKS.
