• During the second quarter a total of 2,966 ounces of gold were produced at the Briggs Mine, of which 1,955 was sold at an average gold price of US$936. Revenue from the second quarter was credited against capitalized costs as the mine continued to be in development.
• Gold production from Briggs totaled 1,756 ounces in the month of July and ramp-up of production to an annualized rate of 40,000 ounces will continue throughout 2009.
• Capital expenditures on the re-start of operations at Briggs totaled US$14.6 million as of June 30, 2009.
• A new estimate of gold mineralization at Briggs, based on recent drilling, resulted in an 11 percent increase in the measured and indicated resource and a 34 percent increase in the inferred resource.

• Pinson Mining Company, a subsidiary of Barrick Gold, has advised the joint venture that the open pit option for Pinson is not viable. The joint venture is discussing other alternatives for the project.

• A positive variance of $0.4 million in general and administrative expenses was due primarily to a decrease in expenses related to merger costs incurred during the first half of 2008 and a strong attention to cost controls.
• A negative variance of $0.4 million related to exploration expense at the Cecil R property.
• A negative variance of $0.2 million due to a lower unrecognized gain on non-financial derivatives due to a higher gold price which decreased the fair market value of the gold hedges.

Cautionary Note to U.S. Investors --- The United States Securities and Exchange Commission permits U.S. mining companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally extract or produce. We use certain terms in this report, such as "measured," "indicated," "inferred," and "resources," that the SEC guidelines strictly prohibit U.S. registered companies from including in their filings with the SEC.
