According to reports given at the International Convention of Mining Investors held in Toronto, Canada, fields in the DRs Monte Plata Province have veins with enough gold and zinc to be profitable to mine commercially. Octavio L?pez, Director of Mining in the DR, reported to the convention that a study conducted recently at the San Antonio Uno concession site at Yamas? revealed 8.55% concentration of zinc in samples of the vein there, 3.39% gold and 0.13% lead. An executive of Energold Mining Ltd. quoted by Ultima Hora said that all their explorations in the area indicate sufficient gold to be profitable to mine. "Every hole we dig there finds a massive mineral deposit." L?pez said that his office has granted 12 licenses to explore for minerals throughout the DR, while applications for 11 more are pending.
