GEO ratios are computed by dividing the average realized gold price per ounce by the average realized silver price per ounce received by the Company in the respective period. Preliminary GEO ratios are listed above:

Fire Creek – Nevada:
At Fire Creek, the Company milled 49,060 ore tons in the second quarter at an average milled head grade of 1.01 gold equivalent ounces per ton, producing 45,733 gold equivalent ounces. YTD, Fire Creek has produced 64,966 gold equivalent ounces, approximately 66% of its annual production guidance. In the second half of the year, Fire Creek will increase waste development activities. This will result in producing fewer ore tons at similar grades. We continue to expect to meet our annual production guidance of 97,000 to 100,000 gold equivalent ounces.

Midas – Nevada:
At Midas, the Company milled 43,172 ore tons in the second quarter at an average milled head grade of 0.36 gold equivalent ounces per ton, producing 13,962 gold equivalent ounces. YTD, Midas has produced 25,366 gold equivalent ounces, approximately 59% of its annual production guidance. Midas will increase its development activities in the second half of the year, thus producing fewer ore tons at similar grades. We continue to expect to meet our annual production guidance of 42,000 to 45,000 gold equivalent ounces.

Hollister – Nevada:
At Hollister, the Company mined 15,162 ore tons in the second quarter at an average mined head grade of 0.47 gold equivalent ounces per ton for a total of 7,069 gold equivalent ounces, which were stockpiled at the end of the second quarter. Stockpiled ore is expected to be processed at the Midas mill in the second half of the year after metallurgical test work is completed. Mining rates are expected to increase significantly in the second half of the year as we complete development activities and increase cut and fill and long hole mining rates. We continue to expect to meet our annual production guidance of 30,000 to 35,000 gold equivalent ounces.

True North – Canada:
At True North in Canada, the Company milled 44,484 ore tons in the second quarter from the True North Mine at an average milled head grade of 0.14 gold ounces per ton, producing a total of 5,798 gold ounces. The Company also milled 25,191 tons from the True North Tailings at an average milled head grade of 0.05 gold ounces per ton producing an additional 1,113 gold ounces. Additional ore tons are expected to come from the Cohiba mine as development work commenced in the second quarter. We expect to meet our annual production guidance of 41,000 to 45,000 gold ounces from multiple ore sources.
