General comments

Subject category Comment text
Deposit MOST BRECCIATED, SILICIFIED, AND LIMONITIC ZONES ARE WEAKLY MINERALIZED. SOME, HOWEVER, ARE HIGHLY MINERALIZED CONTAINING UP TO 141. OZ/TON AG (SAMPLE 19 OF SATKOSKI AND SOKASKI). MINERALIZED ZONES INVARIABLY HAVE SMALL LATERAL EXTENT.
Deposit JOHNSON CANYON HAS FEW EXPOSURES OF SILVER-BEARING ROCK, BUT MAJOR SUBSURFACE MINERALIZED STRUCTURES MAY BE PRESENT. HIGH SILVER CONTENT IN THE MINERALIZED ROCKS ON AND NEAR THE PATENTED CLAIMS IS COMMONLY RELATED TO BRECCIATION AND SILICIFICATION ALONG NORTH-TRENDING FAULTS. OTHER AG LOCALES ARE IN SILICIOUS LIMONITE ALONG BEDDING PLANES AND CROSS FAULTS, OR IN SMALL PODS, BUT MAJOR SUBSURFACE MINERALIZED STRUCTURES MAY BE PRESENT. NOTE: EVENING NO. 1 MINE AND EVENING NO. 2 MINE ARE ON THIS PATENTED CLAIM. ; INFO.SRC : 1 PUB LIT
