| Deposit | DEPOSIT CONSISTS OF GOLD MINERALIZATION OCCURRING ALONG A HIGH-ANGLE FAULT THAT JUXTAPOSES ANDESITE (HANGING WALL) AGAINST THE MT. LAIRD TUFF (FOOT WALL). DRILL HOLES HIT LIMESTONE AT A VERY SHALLOIW DEPTH. AS MUCH AS 1 PPM AU IS IN HIGHLY ARGILLIZED AND LIMONITE STAINED VOLCANIC ROCK IN THE FAULT ZONE. LIMONITE IS OXIDATION PRODUCT OF PYRITE AND SOME LIMESTONE IS PYRITIC. |
