| Deposit | WALLROCKS ARE HIGHLY SHATTERED, CRUMPLED AND ALTERED. MINERALIZATION IS CONTROLLED BY FISSURES RUNNING IN A N-S DIRECTION. |
| Deposit | THE ESTIMATED THICKNESS OF THE UPPER LIMESTONES IS 2,700 FT. THE SEDIMENTARIES ARE INTRUDED BY RHYOLITES OF HIGHLY VARIABLE NATURE. VARIATIONS IN THE APPEARANCE OF THE RHYOLITE ARE THE RESULT OF CHANGES IN TEXTURE, MINERAL CONTENT AND DEGREE OF ALTERATION. ; INFO.SRC : 1 PUB LIT; 3 FIELD OBSERV |
