THIRD QUARTER 2011 OPERATING RESULTS:

The third quarter operating statistics showed improvement over the prior year as well as year to date. Ore production has continued at an annualized rate of more than 11 million tonnes. The west side crusher was disassembled and relocated on the east side of the property to provide a centralized crushing facility with a capacity of 500,000 TPM. The east pad and the east side carbon plant (a duplicate plant of the west side facility with a name plate capacity of 500,000 TPM capacity) were commissioned in October. Production is still expected to finish the year at approximately 70-75,000 ounces with a $575-$600 cash cost.

Recovery rate was 56% for the quarter, up from the prior year's rate of 53% but slightly lower than last quarter. This was a result of higher stacking lifts, downtime associated with moving the crusher and some cyanide shortages at the beginning of the quarter. (Recovery rate is defined as ounces produced over ounces loaded to pads.)

During Q3 of 2011, 13,260 ounces of gold were sold. At September 30, 2011, a large inventory of approximately 6,200 gold ounces from Q3 were on hand and had not been sold, primarily due to volatility in the gold price. The Company sold 6,192 of these ounces in October at an average price of $1,658 per ounce, or roughly $10 million additional cash.

Pete Dougherty, President and CEO of Argonaut Gold noted: 'Quarterly gold production provided meaningful ounces towards our guidance for the year and was slightly impacted by the pad height on the west pad, cyanide availability and the relocation of the crushing circuit to the east side. To date 2011 has shown great promise for Argonaut Gold; key initiatives were completed to provide flexibility in our production profile with the commissioning of the east side plant, construction of heap leach pads, adding new equipment to the mining fleet and finally expanding our land position by 100 hectares to the west.'
