Deposit BANDED AND, LOCALLY WHERE THICKEST, BRECCIATED VEINS 0.3 TO 2.5 M WIDE. BISMUTH VEIN SAID BY OWNER (G. PEREZ) TO CONTAIN GOLD. MANTOS ARE SUBHORIZONTAL ZONES 20M THICK OF ALTERNATING, FRACTURED (N70E, AND N-S SUBVERTICAL) HORNFELSED BEDS OF MARL AND SHALY MARL 1 TO 1.5 M THICK. MINERALIZATION OCCURS AS 1-2 CM BANDS ALONG BEDDING PLANES, AS FRACTURE FILLINGS, AND DISSEMINATIONS OF PYRITE-TETRAHEDRITE-CASSITERITE-TOURMALINE. VEINS OCCUR JUST BELOW MANTOS AND APPEAR TO BE FEEDER CONDUITS FOR MINERALING FLUIDS. CASSITERITE AND WOLFRAMITE ABUNDANCE INCREASES WITH DEPTH.
