| Deposit | THE OLDEST ROCKS ARE DARK GRAY THIN-BEDDED LIMESTONE (PUCARA GROUP, TRIASSIC-JURASSIC) WHICH CROP OUT ONLY TO THE NE AND SW OF THE MINE AREA AND ARE NOT FOUND WITHIN THE MINE. THEY ARE OVERLAIN BY A WHITE CROSSBEDDED QUARTZ-RICH SANDSTONE WITH SUBORDINATE REDDISH SANDY SHALE AND THIN BEDS OF BLACK SHALE AND LOW-GRADE COAL. ABOVE THE SANDSTONE ARE WELL-BEDDED DARK-GRAY LIMESTONES WITH INTERCALATIONS OF RED SHALE AND BRECCIA. NEAR THE BASE OF THE SECTION IS A BED OF DOLOMITE THAT WEATHERS TO A DISTINCTIVE YELLOW COLOR AND IS USEFUL AS A MARKER BED IN MAPPING. THE DOLOMITE CONTAINS ABOUT 9% MAGNESIUM OXIDE, 16% CALCIUM OXIDE, 1.4% IRON OXIDE, AND 46% INSOLUBLE MATERIAL. ALL THE ORE BEDS AT CERCAPUQUIO ARE FOUND IN THIS LIMESTONE UNIT. |
| Deposit | ORE MAY CONSIST OF ALTERNATING BANDS OF ORE MINERALS AND SHALE, WITH SHALE FRAGMENTS IN ORE AND STRINGERS OF ORE MINERALS IN SHALE. ORE MAY BE DISSEMINATED IN RED SHALE OR GOUGE, OR MAY FORM VEINLETS IN FRACTURED LIMESTONE IN THE HANGING WALL. |
