“The El Roble mine performed below schedule this quarter as the transition to the new areas was delayed by unexpected challenging rock quality conditions. Tonnage and particularly head grade were impacted as access to higher grade stopes was slowed down.” said Fernando E. Ganoza, CEO. “We expect to see progressive improvements in the second and third quarter this year to recover the planned development and preparation rate, which will allow us to make up for most of the lost production.”

Mineralization is open at depth and along strike and the Company plans to further test the limits of the deposit. 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.
