Assay results have been received from 17 drill holes: LR037, LR043, LR045, LR050, LR054, LR056, LR061, LR062, LR071, LR073, LR074, LR079, LR080, LR084, LR088, LR091 and LR098 at La Romanera deposit (details reported below). The drill hole intercepts reported here are located in the center to the eastern extent of the deposit. The deposit remains open to the east based on these results. Hole LR073 which intersected 33.1 m grading 0.3 % Cu; 3.9 % Pb; 7.7 % Zn; 0.73 g/t Au and 156.3 g/t Ag, including 10.1 m grading 0.2 % Cu; 9.2 % Pb; 10.3 % Zn; 0.96 g/t Au and 240.6 g/t Ag , occurs at the outer limit of the historical drilling and shows the deposits continues to extend eastwards. Please see Figures 1 and 2 below for drill hole locations and Table 1 for detailed drill hole data.
Six of the drill holes occur within the footprint of the historical drilling and the remainder are outside. Drilling continues to intersect significant higher grades in gold and silver relative to the historical mineral resource estimate, in this part of the deposit. The high gold and silver results are occurring over a wider area than previously thought and in both lenses. Intercepts that have been described as stockwork previously and are characterized by millimetre to centimetre scale veinlets that are particularly rich in copper.
