General comments

Subject category Comment text
Deposit EXPOSURES ARE IN 3 OUTCROP AREAS WIDELY SPACED ALONG A 335 M STRIKE LENGTH. CENTRAL AND SOUTHERN OUTCROPS PART OF WEAKLY AND ERRATICALLY MINERALIZED BEDDED BRECCIA; MINERALIZED WIDTH OF 6.1 M TO 12.2 M IS INDICATED (NOTE: DATA ABOVE IS FOR BRECCIA BED). NORTHERN OUTCROP IS EVIDENTLY UNRELATED, IS SLIGHTLY OFF STRIKE AND 18.3 M STRATIGRAPHICALLY LOWER. BRECCIA MOST CLOSELY RESEMBLES THE "SHATTER" BRECCIAS OF THE EAST TENNESSEE ZINC DISTRICT.
