Comments on the reserve resource information

  • NO SE HAN ESTIMADO RESERVAS, DEBIDO A LO ERRATICO DE LA MINERALIZACION Y A QUE LA UNICA ZONA CON ACCESO ESTA TOTALMENTE EXPLOTADA.

Comments on development

  • EN LAS CONCESIONES "AMERICA" Y "FORTALEZA" EXISTEN CATEOS QUE NO EXPONEN ESTRUCTURAS MINERALIZADAS. EN LA CONCESION "SANTA ROSA", EXISTEN DOS VETAS DE FRACTURA, TIPO ROSARIO CON CONCENTRACIONES ERRATICAS DE MINERAL DE AG AU SB.

Subject category Comment text
Deposit EN LA CONCESION SANTA ROSA EXISTEN DOS VETAS DE FRACTURA. LA FRACTURA PRINCIPAL SE DENOMINA "SANTA ROSA" Y LA SECUNDARIA "SAN LUIS", PARECIENDO SER UN RAMAL DE LA PRIMERA. EL RUMBO Y BUZAMIENTO DADOS, CORRESPONDEN A LA VETA PRINCIPAL YA QUE LA VETA SECUNDARIA NO ES DE GRAN IMPORTANCIA PORQUE PRESENTA MINERALIZACION SOLO EN LA UNION ENTRE AMBAS VETAS.
