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.
