General comments

Subject category Comment text
Deposit SEE PE063 FOR DESCRIPTION OF A PROSPECT WITHIN THIS CLAIM BLOCK. RECENT MAPPING BY THE USGS (SUE KARL, ORAL COMMUNICATION, 1998) INDICATES THAT MUCH OF THIS BLOCK OF CLAIMS CONSISTS OF TRIASSIC HYD GROUP ROCKS THAT HOST THE VOLCANOGENIC MASSIVE SULFIDE DEPOSITS OF THE DUNCAN-ZAREMBO BELT DEFINED BY BERG AND GRYBECK (1980), AND BERG (1981).
