Comments on development

  • LA MINA SINCHI ROCA HA SIDO EXPLORADA MEDIANTE UNA GALERIA DE 145 M. Y ADICIONALMENTE OTRAS LATERALES Y TRANSVERSALES DE CORTA LONGITUD. LAS EXPLORACIONES EFECTUADAS HAN ALCANZADO UNA SUFICIENTE PROFUNDIDAD EN HORIZONTE Y VERTICALMENTE PARA DEMOSTRAR QUE LA MINERALIZACION ECONOMICA TIENE VALORES OXIDADOS Y SUB-COMERCIALES.
