Comments on the reserve resource information

  • SE HAN LIMITADO EN CUANTO A MAGNITUD Y CONTENIDO LAS RESERVAS INFERIDAS DEBIDO A QUE EL SKARN, NO SE ENCUENTRA UNIFORMEMENTE MINERALIZADO EN TODOS LOS SECTORES.

Comments on the workings information

  • LAS LABORES MINERAS TIENEN UNA GALERIA PRINCIIPAL QUE EXPONE MINERALIZACION DESDE LA BOCAMINA HASTA LOS 10 M.; EN EL PUNTO DE LA BOCAMINA +21 SE HA EJECUTADO UN CRUCERO DE 10 M. HACIA EL W, Y QUE INTERCEPTA EL FLANCO OCCIDENTAL DE LA AUREOLA DE CONTACTO. EN EL PUNTO DE LA BOCAMINA +36 M. SE HA DESARROLLADO UN CRUCERO AL E. TOTALMENTE ESTERIL. EN EL PUNTO DE LA BOCAMINA +42 M. SE HA CORREGIDO EL DESARROLLO DE LA GALERIA ORIENTANDOLA HACIA EL W.

Comments on development

  • LOS DESARROLLOS RECIENTES, Y LA IRREGULARIDAD QUE ES CARACTERISTICA DE METASOMATISMO DE CONTACTO, ESTOS DESARROLLOS INDICAN QUE LAS RESERVAS PROBABLES SE HAN REDUCIDO EN FORMA CONSIDERABLE.
