Subject category Comment text
Deposit ESTE YACIMIENTO OFRECE POSIBILIDADES INTEREZANTES DEBIDO A LEYES CONSIDERABLES DE AG Y AU CON AFLORAMIENTOS DE 100 M Y UN ANCHO 15 M. AUNQUE SE TIENE DIFICULTAD EN LA RECUPERACION DEL MINERAL (POR PALLAQUEO) POR ESTAR DESIMINADO,FAVORECE A LA INSTALACION DE UNA PLANTA DE CONCENTRACION POR FLOTACION PARA OPTIMIZAR SU RECUPERACION DEL CUERPO MINERAL.
