Deposit LAS VETAS ESTAN CONFORMADAS POR FRACTURAS TENSIONALES ORIGINADAS POR EL ENFRIAMIENTO DEL INTRUSIVO Y RELLENO POSTERIOR CON SULFUROS. LAS PRINCIPALES VETAS SON CANDELARIA, SAN ROQUE, TOLDOJIRCA, SANTA ROSA, VETA 21, SAN FELIPE. LOS CUERPOS DE REEMPLAZAMIENTO SE UBICAN EN LOS ESTRATOS ALTERADOS DE BLOCKS DE CALIZA ENGLOBADOS EN EL INTRUSIVO, TAL COMO SE TIENE EN EL CUERPO LA TAPADA. ESTE CUERPO SE SITUA 550 METROS DEBAJO DEL CONTACTO DEL INTRUSIVO CON LAS CAPAS ROJAS. CUERPO DE BRECHA TECTONICA, DONDE LA MINERALIZACIN SE HA DEPOSITADO EN LOS ESPACIOS PERMEABILIZADOS POR INTENSO FRACTURAMIENTO DENTRO DE LA ROCA INTRUSIVA ES CONOCIDA COMO CUERPO CANDELARIA.
