Subject category Comment text
Deposit NO VEIN STRUCTURES WERE OBSERVED, BUT THE DUMP ROCK CONSISTS OF QUARTZ-CEMENTED LIMESTONE BRECCIA, INDICATING THAT THE ADIT MAY FOLLOW A QUARTZ OR BRECCIA VEIN CUTTING THE LIMESTONE HOST. THE BRECCIA IS CEMENTED WITH PRISMATIC (COMB) TO MASSIVE WHITE QUARTZ WHICH CONTAINS RHOMBS OF TETRA HEDRITE WITH RIMS OF CRYSTALS ALTERED TO CU OXIDES, MINOR PYRITE, MALACHITE AND GHOSTS AFTER SB? MINERAL. THE LOWER ADIT EXPLORES THE CONTACT BETWEEN AN ALTERED RHYOLITE (?) DIKE AND LIMESTONE HOST ROCK. THE DIKE IS EXPOSED AT PORTAL LEVEL AND IS SO THOROUGHLY ALTERED TO CLAY (ARGILLIZED) AND FE OXIDES THAT NOTHING COULD BE DETERMINED ABOUT ITS ORIGINAL TEXTURE OR COMPOSITION. DIKE IS PARALLEL TO LIMESTONE BEDDING.
