Comments on the reserve resource information

  • SEGUN EL PLAN DE DESARROLLOS PROYECTADOS, DE CONTINUAR LA MINERALIZACION HACIA EL OESTE EN UNOS 30 MTS SE PODRIA ESTIMAR EN UNOS 2,000 TM DE MINERAL PROSPECTIVO CON LEYES SIMILARES PARA LOS MINERALES PROBADO-PROBABLE

Comments on the workings information

  • LA MINA ESTA ACTUALMENTE PARALIZADA.

Comments on development

  • EL DEPOSITO MINERAL HA SIDO DESARROLLADO PIR UN NIVEL PRINCIPAL ACCESIBLE HASTA LOS 19 MTS (LA CONTINUACION DE LA MINA ESTA DERRUMBADA). EN LA GALERIA PRINCIPAL, LA VETA HA SIDO TAJEADA Y RELLENAD EN SU PARTE MAS RICA HASTA LA SUPERFICIE, SOLAMENTE FALTA DESARROLLAR Y EXPLOTAR LA NUEVA ESTRUCTURA ENCONTRADA CON LA ESTOCADA HACIA EL SUR DESDE EL SUBNIVEL. ; ECON.COM: EL MINERAL PERMITE LA OBTENCION DE UN CONCENTRADO DE COBRE Y PLATA CON ALTAS LEYES DE AMBOS ELEMENTOS Y UN CONTENIDO INTERESANTE DE ORO.
