Deposit WORKINGS EXPLORE A 10-15 FT THICK REPLACEMENT BED IN LIMESTONE. BEDDING IS GENERALLY HORIZONTAL WITH A SLIGHT INCLINATION OF 5-10 E. MOST ROCKS AT MINESITE ARE MEDIUM TO THICK-BEDDED, ARGILLACEOUS MARLY GREY-BROW TO YELLOWISH TAN LIMESTONES, SOME RECRYSTALLIZED AND/OR SHOWING ALGAL STRUCTURES. MASSIVE LIMESTONE CLIFFS (HIGHLAND PEAK FM) LIE SEVERAL HUNDRED FEET ABOVE THE MAIN WORKINGS, AND CHISHOLM (?)SHALE OUTCROPS 50-80 FT UPSLOPE FROM WORKINGS, INDICATING THAT MINE IS PROBABLY IN UPPER LYNDON LIMESTONE. THE EXPLORED HORIZON IS CHARACTERIZED BY LIGHT RED HEMATITE, LIMONITE, AND SPARSE MN OXIDES. THE CEILING OF THE WORKINGS CONSISTS OF MARLY ORANGE-BROWN LIMESTONE,FINELY CRYSTALLINE, WITH POCKETS OF LIMONITE, LENSES OF FE-MN OXIDES, AND RANDOM CALCITE VEINS AND VEINLETS. THE REPLACEMENT HORIZON IS DARK BROWN, MORE COARSELY CRYSTALLINE AND MARLY IN APPEARANCE. NBMG SAMPLE 1438 CONSISTS OF DARK RED-BROWN LIMESTONE OF THIS TYPE WITH IRREGULAR WHITE VUGGY CALCITE VEINS,GALENA AND PYRITE.
Deposit SULFIDES ARE GENERALLY VERY FINE GRAINED. THE ROCKS ARE QUITE DENSE, POSSIBLY DUE TO FINE-GRAINED DISSEMINATED SULFIDES, OR BARITE. SOME SPECULARITE WAS NOTED ON FRACTURE SURFACES, AND ALSO SOME SILICIFICATION OF WALLROCK. EVIDENCE OF SHEARING OR BRECCIATION ALONG BEDDING PLANE FAULT IS VISIBLE WITHIN WORKINGS, INDICATING REPLACEMENT MAY HAVE BEEN PARTIALLY CONTROLLED BY THE BEDDING PLANE FAULT. OTHER FACTORS INFLUENCING MINERALIZATION, ACCORDING TO THE LITERATURE ARE THE SCODDE FISSURE (N70E) AND LAMPROPHYRE DIKES. ORE EXTENDS ALONG BEDDING 25 FT ON EACH SIDE OF FEEDING FISSURE; VERY LITTLE ORE OCCURS IN THE FISSURE ITSELF. ORE IS FAULTED OFF ON THE EAST BY A N20E FAULT.
