Comments

Comment (Production): SEVERAL SMALL SHIPMENTS OF PB-AG ORE WERE MADE IN THE YEARS 1924-1926 (NOLAN, 1935, P. 156).

Comment (Development): THE USBM OPEN FILE REPORT (MINERAL PROPERTY FILE 4.1INCLUDES EXCELLENT SURFACE AND UNDERGROUND GEOLOGIC MAPS AND A LONGITUDINAL SECTION OF THE WORKINGS. A SEVEN HOLE DRILLING PROGRAM WAS PROPOSED IN THE REPORT.

Comment (Deposit): THE LIMITS OF THE ORE BODY HAVE BEEN DIFFICULT TO DETERMINE IN AREAS LACKING A QTZ. MONZONITE CONTACT OR A POST-MERAL FAULT.

Comment (Workings): AN INCLINED SHAFT CONNECTS THE 100, H (PRINCIPAL LEVVEL), AND 234 (200 FT. IN THE USBM REPT.) LEVELS; A VERTICAL SHAFT FROM THE SURFACE CONNECTS WITH THE 100 FT. LEVEL. THE 100 FT. LEVEL IS KNOWN AS THE "WORKING" LEVEL, WAS EXTENSIVELY STOPED, AND IS MOSTLY INACCESSIBLE.

Comment (Geology): THE NORTH END OF THE ORE BODY IS ENRICHED IN LEAD, ZINC, AND SILVER; THE SOUTH END IS ENRICHED IN ARSENIC
