Deposit ASOCIADAS A ROCAS ANDESITAS OCURREN DOS ESTRUCTRAS MINERALIZADAS DENOMINADAS: VETA JUANITA Y VETA MANUELITA. LA ETA JUANITA TIENE UN AFLORAMIENTO OBSERVABLE DE 250 M RUMBO S-75-W, BUZAMIENTO 70-S Y UNA POTENCIA PROMEDIO DE 1.00MTS. LA VETA MANUELITA TIENE UN AFLORAMIENTO DE 100 MTS RUMBO S-64-W Y BUZAMIENTO 70-S POTENCIA PROMEDIO 0.80 MTS . EN AMBOS LA MINERALIZACION SE PRESENTA EN FORMA ERRATICA.
Deposit SE CONSIDERA QUE LA EJECUCION DEL PROYECTO TIENE POSIBILIDADES FAVORABLES PARA LOCALIZAR MINERAL DE MAYOR RENDIMIENTO ECONOMICO QUE EL ACTUAL. ; INFO.SRC : 2 UNPUB REPT
