NEWS RELEASE

Operating and Financial Results for the
Three Months Ended June 30, 2010
San Francisco Mine Generates $1.9 Million in
Net Profits before Tax

Timmins Gold Corp., (“Timmins” or the “Company”) is pleased to report on its first ever operating and financial results since commercial operations at its flagship San Francisco Mine commenced on April 1, 2010. All currency in this report is in Canadian dollars unless otherwise indicated.

The major highlights for the three months ended June 30, 2010 include the following:

• Commercial operations were deemed to commence on April 1, 2010 following a commissioning period of less than five months;

• The San Francisco Mine averaged a mining rate of 1.7 million tonnes per month during this first quarter of commercial operations and on average 301,765 tonnes of ore were placed on the leach pads (or 10,059 tonnes per day);

• The Company produced and sold 11,299 ounces of gold and 6,696 ounces of silver, realizing gross proceeds of $14.3 million;

• The San Francisco Mine generated net profit before tax of approximately $1.9 million and cash flow from operations of $1.4 million during its first quarter of operations.

• Operating costs, excluding depreciation, at the San Francisco Mine were $13.67(US $13.30) per tonne placed on leach pads or $946 (US $920) per ounce produced and sold, net of by-product credits. These costs are on line to reduce to $520 per ounce by year end and to reach the $420 per ounce life of mine projections.

• For the calendar year, the Company has produced and sold 16,619 ounces of gold and 10,374 ounces of silver, realizing gross revenue of $22.6 million;

• In April, as a result of the first phase of this year’s exploration program the Company announced an increase in the resources at the San Francisco Mine of 25%;

• For the three months ended June 30, 2010, the Company reported a net loss of $4.1 million or $0.03 per share compared to a loss of $0.8 million or $0.01 per share for the comparable quarter in 2009; the Company recognized interest expense and a loss on the embedded derivative in connection with the gold loan financing (both of which were non-cash items) of $5.0 million or an amount in excess of the total loss for the quarter;

• The loss on the embedded derivative is measured by the product of the change in the quarter ending gold prices, adjusted for foreign exchange and time value of money considerations;

• For the three months ended June 30, 2010 cash flow from operating activities was $605,010 compared to a use of cash of $324,116 for the three months ended June 30, 2009; and

• The Company reported net income from operations of $0.9 million for the recently completed quarter.

CONSOLIDATED RESULTS

For the three months ended June 30, 2010, Timmins reported a net loss of $4,090,157 or $0.03 per share on revenue of $14,332,597. This compared to a net loss of $804,330 or $0.01 per share during the three months ended June 30, 2009, a period during which development of the San Francisco Mine had not yet commenced. The financial performance of the Company benefitted from continued strong gold prices and a successful and improving operating performance at the San Francisco Mine offset by expenses recognized on the gold loan.

Cost of goods sold totaled $10,845,997 or $945.89 per ounce of gold sold, net of by-product credits. Depreciation and amortization was $1,215,903 or $107.62 per ounce of gold sold. General and administration costs (including non-cash stock based compensation expense of $553,013) were $1,326,537 for the current quarter, compared to $1,236,190 for the comparable quarter in 2009. In the comparable quarter for 2009, stock based compensation expense was only $49,023.

The asset retirement obligation was $30,741 (2009:$3,621) and other miscellaneous expenses were $2,652, relating to abandoning the Tequila property in March 2010.

During the quarter, the requirement to fair value the embedded derivative in the gold loan resulted in a non-cash expense of $2,599,745 a result of the price of gold increasing by $128.50 per ounce between March 31, 2010 and June 30, 2010. However, the non-cash loss on the embedded derivative is mitigated by the fact that this financial instrument did not require the hedging of any production in late 2009 when gold prices are lower than they are today. The interest expense on the gold loan for the quarter was $2,413,778, and it was also a non-cash item this quarter as repayment of the gold loan does not commence until the end of August 2010.

• Significant improvements to grade control in the pit were implemented;

• The mining contractor brought another drill onto the property to expand production;

• To further improve mining productivity and reduce costs the mining contractor has agreed to supplement the existing fleet with two additional drills (one of which is on-site), three additional haul trucks, and one more shovel; and
