On the larger land package, the Company has identified a prospective stratigraphic contact

between volcanic rocks and black and grey pelagic sediments and cherts that has been traced by

Atico geologists for ten kilometers. This contact has been determined to be an important control

on VMS mineralization on which Atico has identified numerous target areas prospective for

VMS type mineralization occurrence, which is the focus of the current surface drill program at

El Roble.
