VANCOUVER, BRITISH COLUMBIA-- July 13, 2011-SilverCrest Mines Inc. (the "Company") (TSX VENTURE:SVL) is pleased to report it has achieved Commercial Production at its 100% owned Santa Elena mine located in Sonora, Mexico. Commercial Production is deemed to have commenced when management determines that the operational commissioning of the mine shows:

• a significant portion of mining, crushing, plant operating capacity has been achieved;
• all facilities are operating at a steady state of production; and
• a pre-determined, reasonable period of operating time has passed.

Prior to achieving commercial production, revenues and related expenses have been recognized in Property Plant and Equipment as a reduction or increase respectively to carrying values of mining assets. Q2 of 2011 will be the first period reported as being commercial whereby revenues and expenses will be presented in forthcoming consolidated interim financial statements.

During 2011, which will be a partial year at full production rates, and based on the current life of mine plan, the mine is expected to produce approximately 430,000 ounces of silver and 26,000 ounces of gold. The first full year of production will be 2012 during which the mine is expected to produce 478,000 ounces of silver and 32,000 ounces of gold. From 2013 through 2016, there is a significant increase in recovered silver ounces of an estimated 750,000 to 1.1 million ounces per year.

The following summarizes the main highlights during the respective periods of the Commissioning Phase of Santa Elena and the first quarterly period of commercial production ending June 30, 2011;

• The crusher is currently operating above daily designed throughput of 2,500 tpd with an average of 2,583 tpd for the period January through June 2011 and anaverage of 2,737 tpdduring Q2, 2011.

• Estimated initial silver recovery of 21% and gold recovery of 38% are consistent with budgeted numbers of 24% for silver and 41% for gold during the Commissioning Phase. Projected total metal recoveries of 35 to 40% silver and 65 to 70% gold which are based on a 300 day leach cycle appear to be achievable. The average time under leach for the Main Zone higher grade ore is currently at 60 days.

• The Main Zone is now being mined and leached with leach recovery times similar to the extensive Metcon metallurgical testing and bulk column test work. In June high grade ore being delivered from the Main Zone to the pad averaged approximately53.35 gpt Ag and 1.97 gpt Auand the overall grade of the ore on the pad has increased from 40.35 gpt Ag and 0.60 gpt Au in January to 41.28 gpt Ag and 1.03gpt Au at the end of June.

• Metal production has increased steadily from 64,712 ounces of silver and 3,152 ounces of gold in Q1 to74,678 ounces of silver and 5,476 ounces of gold in Q2, 2011.

• Loan payments of US$1.3 million and US$800,000 were made from production revenues to Macquarie Bank Limited on March 31, 2011 and June 30, 2011, respectively, Loan obligations of US$5.6 million remain for fiscal 2011. As of June 30, 7,515 ounces of gold had been delivered in to the Macquarie gold price protection program.

• 1,879 ounces have been delivered to Sandstorm under the gold stream agreement to the end of Q2, 2011.

• No lost time accidents since construction started in 2009 with over 560,000 hours worked.

• The Company currently has approximately$34.5 million in cash.

J. Scott Drever, President stated; "We are certainly pleased at this time as to how the Commissioning Phase for the Santa Elena operations has progressed. All aspects of the operations are at design capacities and are functioning as expected with the exception of the crusher. We have experienced a number of operating challenges with crusher operations which have required operating times to be increased to an average of 18 hours per day rather than the budgeted 14 hours to meet production targets. Our supervisory personnel have worked diligently to assure that the normal start-up challenges were resolved and the project has reached a steady state at design capacity. The receipt of substantial revenues from the sale of our silver and gold production has reduced the amount of working capital required during start up and has set the stage for early, free cash flow that will be utilized to implement the Company's strategy for corporate growth."
