The second quarter production showed improvement for the sixth consecutive quarter as well as year over year. Mine ore production has improved to an annualized rate over 11 million tonnes. Crushing capacity at the west plant has continued year over year improvements of 218% and is now running at an annualized rate of 3.4 million tonnes. Production was strong at 17,453 ounces, a 73% improvement year over year. Recoveries were 59% for the quarter, an improvement over prior year's rate of 50% but lower than last quarter. (Recovery rate is defined as ounces produced over ounces loaded to pads). This was due to lower cyanide concentration and flow rate to the pad coupled with higher stacking lifts. The lower cyanide concentration was due to a shortfall of cyanide resulting from the Company's supplier experiencing flooding at their production facility. The Company has addressed this issue by sourcing cyanide from alternative sources. Currently, the Company has a sufficient cyanide supply at site and the Company's primary supplier has reestablished production flow to the site. The Company expects this set back to not impact full year production guidance of 70 - 75,000 gold ounces.
