Noting El Castillo's continuous improvements and increase in production, Argonaut's President and CEO Peter Dougherty noted:

"The 3rd quarter marks the third consecutive quarter of increased gold production at El Castillo (12,724 ounces). During the 3rd quarter there were 24,202 ounces delivered to the pad. This was a record month for ounces delivered to the pad at El Castillo. Upgrades to the west side processing plant more than doubled the previous flow rate.

The capital expansion program is scheduled for completion by year end, which will include commissioning of the east side processing plant. Combined, the two plants' facilities will provide a processing capacity of over 1 million tonnes of ore per month.

October demonstrated production abilities of operations at El Castillo following the CAPEX improvements. October production was over 5,000 ounces, with over 1.5 total tonnes mined. The improvements made at the El Castillo mine were key to establishing a 75,000 ounce run rate in 2011."

This press release should be read in conjunction with the Company's unaudited consolidated interim financial statements for the quarter-ended September 30, 2010 and associated Management's Discussion and Analysis ("MD&A") which are available from the Company's website www.argonautgoldinc.com, in the "Investors" section under "Financial Filings", and under the Company's profile on SEDAR at www.sedar.com.

Summary of Production Results:

Year over year, total tonnes mined increased by +83% for the quarter. With a full quarter of utilizing a larger, more efficient truck fleet at El Castillo, the rate of mining production exceeded 1.5 million tonnes per month. The total of ounces loaded to the pads also increased. In the 3rd quarter 24,202 ounces were placed on the pad, representing a 20% increase over 2nd quarter in 2010.

Gold production of 12,724 ounces in the third quarter of 2010 was a 66% increase compared to the third quarter of 2009.

The 3rd quarter strip ratio was slightly higher than previous quarters. The Company chose to begin mining the $1,000 pit limit in accordance with the arrival of the new larger capacity fleet. This was done in anticipation of the new 43-101 technical report to be completed and released in January 2011. The strip ratio is expected to return to the range historically mined at El Castillo.

Key operational metrics and production statistics for the third quarter of 2010 compared to 2009 are presented below:

Financial Results - Third Quarter 2010

During the third quarter of 2010, revenue was $9.8 million compared to $7.0 million for El Castillo in Q3 of 2009 as reported by Castle Gold Corporation ("Castle Gold") for the El Castillo Mine in its Management's Discussion and Analysis for the Quarter ended September 30, 2009 posted on November 26, 2009 on www.sedar.com. The increase in revenue is due to more gold ounces sold and higher gold prices. During the third quarter of 2010, cost of sales and depletion, depreciation and accretion expenses were $6.7 million. Cash cost per gold ounce for units sold was $622. (Cash cost per gold ounce for units sold is a non-GAAP measure and is cost of sales less silver sales divided by gold ounces sold.) Income from mining operations was $3.2 million and net income was $345,358. Cash cost per ounce of gold produced was $621. (Cash cost per ounce of gold produced is a non-GAAP measure and is mining and processing cost over units produced.)

During the nine months ended September 30, 2010, revenue was $31.7 million compared to $18.1 million for El Castillo as reported by Castle Gold. The increase in revenue is due to 7,343 more gold ounces sold and higher gold prices. During the first nine months of 2010, cost of sales & depletion, depreciation and accretion expenses were $25.0 million. Cost of sales included 11,032 gold ounces, of the 26,779 gold ounces sold, that were fair valued at acquisition of Castle Gold at market price of gold less cost to process units. The year-to-date cash cost per gold ounce for units sold (a non-GAAP measure) was $809 which includes the above fair value adjustment. During the first nine months of 2010, income from mining operations was $6.6 million and net loss was $1.6 million. During the first nine months of 2010, cash cost per ounce of gold produced (a non-GAAP measure) was $605.
