Deposit WORKINGS ALONG WILLOW CREEK WERE NOT ACCESSIBLE BECAUSE OF BORAX CO. POLICY, HOWEVER, THEY WERE IN HIGHLY ALTERED VOLCANIC RHYOLITES AND TUFFS, IN SAME TARGET AREA BEING DRILLED BY COMPANY. THE OLDER WORKINGS TO THE NORTH WERE ALONG QUARTZ VEINS IN OLDER SEDIMENTS OF THE AULD LANG SYNE GROUP. SAMPLE 2825 WAS FROM A VEIN CROSSING A STREAM COURSE IN SEDIMENTS THAT WERE BEING PROSPECTED BY A SMALL ADIT. THE VEIN WAS A HIGHLY OXIDIZED, SILICIFIED BRECCIA. SAMPLE 2826 WAS FROM A DUMP ADJACENT TO A COLLAPSED SHAFT IN BRECCIA AND QUARTZ VEINS. MORE PROSPECTS SIMILAR TO THESE DOT THE LANDSCAPE ALONG THE WEST SIDE OF THE RANGE WITHIN THE OLDER SEDIMENTS.
Deposit DEVELOPED BY AN INCLINED SHAFT, 200 FOOT MAIN DRIFT, AND THREE STOPES, AS WELL AS A NEW OPEN PIT. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV
