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 (Workings): THE MAXIMUM SURFACE AREA POTENTIALLY DISTURBED, 30 HECTARES, WAS ESTIMATED BY THE UTAH GEOLOGICAL AND MINERAL SURVEY.

Comment (Ownership): THE MILL RECOVERY OF LEAD AS PROPOSED IS LOW; HOWEVER, IT IS CLOSE TO ACTUAL DATA PROVIDED BY KENNECOTT MINERALS COMPANY PERSONNEL. THE OTHER MILL RECOVERIES PROPOSED ARE SPECULATIVE. IN SEPT 1994 CENTURIAN MINES CORP. REPORTED 100% OWNERSHIP IN THE MAMMOUTH MINE (CENTURIAN MINES CORP 1993 ANN REPT. P. 3.)

Comment (Reserve-Resource): QUANTITY MATRIX 1 WAS BASED ON THREE SOURCES OF INFORMATION: THE RESERVE ESTIMATE MADE IN 1976 BY THE UTAH GEOLOGICAL AND MINERAL SURVEY AND A PRODUCTION ESTIMATE MADE BY THE EVALUATOR (FROM 10-K FORM REPORTS OF YEARS 1977, 1978, AND 1979). THE GRADE COMES FROM UGMS OPEN-FILE REPORT 22, P. 210.
