Financial Results – Second Quarter 2011

During the second quarter of 2011, revenue was $21.6 million from gold sales of 14,331 ounces compared to $12.5 million from sales of 10,387 ounces in the second quarter of 2010. Cost of sales and depreciation, depletion and amortization expenses were $11.0 million for the quarter. Cash cost per gold ounce for units sold (see Non-IFRS measures section note below) was $578 compared to $712 in the same period of 2010 principally because some ounces sold in the second quarter of 2010 had been fair valued on the acquisition of Castle Gold. During the second quarter of 2011, operating income from mining operations was $10.6 million compared to a $3.5 million operating income in the second quarter of 2010. Net income for the quarter was $5.2 million, or $0.06 per share.

Cash on hand decreased from $34.2 million at March 31, 2011 to $32.3 million, as a result of $11.3 million in cash used for payment of expenditures on mineral properties, plant and equipment and the timing of delivery and sale of ounces produced during the quarter that were not sold until early July. Cash flow from operations before changes in non-cash operating working capital and other items was $7.6 million. The cash flow provided by operating activities in the quarter was $8.4 million; again this was impacted by the timing of gold shipments and sales.

Summary of Production Results

Total tonnes mined increased by 44% for the second quarter 2011 over the second quarter of 2010. Once again utilizing a larger, more efficient truck fleet at El Castillo for the full quarter, the rate of mining production exceeded 1.65 million tonnes per month. Total ounces loaded to the pads also increased. In the second quarter of 2011, there were 29,555 ounces placed on the pad, representing a 47% increase over the 20,112 ounces placed on the pad in second quarter of 2010.

Gold production of 17,453 ounces in the second quarter of 2011 was a 73% increase compared to the second quarter of 2010.

The strip ratio of waste to ore declined in the second quarter of 2011 to 0.78 compared to the second quarter of 2010 of 0.85. (The new NI 43-101 compliant technical report for El Castillo indicates the anticipated strip ratio is approximately 0.88 for the life of mine).

Key operational metrics and production statistics for the second quarter of 2011 compared to the respective period in 2010 are presented below:

Non-IFRS Measures

The Company included the non-IFRS measure “Cash cost per gold ounce for units sold” in this press release to supplement its financial statements which are presented in accordance with International Financial Reporting Standards (“IFRS”). Cash cost per gold ounce for units sold is equal to cost of sales less silver sales divided by gold ounces sold. The Company believes that this measure provides investors with an improved ability to evaluate the performance of the Company. Non-IFRS measures do not have any standardized meaning prescribed under IFRS. Therefore they may not be comparable to similar measures employed by other companies. The data is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. Please see the MD&A for full disclosure on non-IFRS measures.
