• 8 metres grading 9.92 g/t gold, 20.78 g/t silver and 0.63 % copper or 11.45 g/ ton gold equivalent*, including 2.0 metres grading 28.87 g/t gold, 20.3 g/t silver and 0.68% copper (30.46 g/t gold equivalent). 
• 10 metres grading 3.03 g/t gold, 12.9 g/t silver and 0.61% copper or 4.35 g/t gold equivalent, including 4.0 metres grading 7.47 g/t gold, 29.35 g/t silver and 0.71% copper or 9.26 g/t gold equivalent.

Brian E. Robertson, President and CEO, commented, "We are very encouraged by these recent sampling results. Historical mining at Changaro, one of the primary targets on the Property, was very selective and focused on very high grade ore. These sampling results clearly demonstrate that mineralization with significant grade and widths extend into the hanging wall and footwall of the historical stoping areas.

Results of the sampling program are shown in Table 1.

(*) Gold equivalents calculations use metal prices of US$ 1300/oz. for gold, US$ 25.00/ oz. for silver and US$3.50/lb. for copper. No adjustments have been made for potential relative differences in metal recoveries.

Au EQ g/t equals Au g/t + (Ag g/t x 0.019) + (Cu% x1.77)
