General comments

Subject category Comment text
Deposit SHALEY SEDIMENTS ARE BADLY BROKEN AND INTRUDED LOCALLY BY A RHYOLITE BRECCIA WHICH LOCALLY TRENDS N10W AND HAS MINOR CRYSTAL-RICH VEINS AND VEINLETS ASSOCIATED WITH IT. FROM A NE-TRENDING ADIT, THE WORKINGS HAVE STOPED THROUGH TO THE SURFACE ALONG THE STRIKE OF A VEIN, AT LEAST 4 TIMES OVER 300 FT. MUCH OF THE MATERIAL REMOVED FROM THESE WORKINGS ARE NOW ON THE HEAP LEACH PILE AT THE BOTTOM OF THE CANYON.
