SilverCrest Santa Elena Mine Commissioning Phase Update Silver and Gold Sales Reported

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 04/13/11 -- SilverCrest Mines Inc. (TSX VENTURE: SVL) (the 'Company') is pleased to report on start-up production and commissioning phase activities at its 100% owned Santa Elena mine located in Sonora, Mexico. Based on revised reserve estimates, mine plan and leach cycle, the open pit mine is expected to produce approximately 800,000 ounces of silver and 30,000 ounces of gold per full year of production at an estimated life of mine cash cost of US$8 per ounce of silver equivalent using a 55:1 Ag:Au ratio on a recovered ounce basis. Based on start-up production for the first quarter and assuming Commercial Production (near design capacity and steady-state) is achieved by June, the mine is expected to produce approximately 430,000 ounces of silver and 26,000 ounces of gold for 2011. The most significant commissioning activities completed to December 31, 2010 and March 31, 2011 are outlined below.

--  Ounces to leach 597,500 Ag, 14,940 Au

--  Ounces poured to dore 119,598 Ag, 5,292 Au

--  Ounces sold 85,064 Ag, 3,266 Au

--  Gross proceeds US$5,348,000

Production and Commissioning Activities to December 31, 2010

--  Approximately 336,000 tonnes of lower grade ore (includes 15,000 tonnes
    of old dumps) have been crushed from the open pit at a strip ratio of
    waste to ore of approximately 2:1. Mining of these lower grade tonnes
    (average grade of 0.60 gpt Au and 40.2 gpt Ag) was necessary to provide
    working space for equipment in the initial cut and to create a lower
    angle for the ultimate pit high wall for safety reasons. This lower
    grade material is considered pre-strip for the higher grade Main Zone
    which is now being mined and will provide the bulk of the ore to be
    mined in 2011.

--  The crusher operated at near design throughput capacity of approximately
    2,500 tpd. There was approximately 35,000 tonnes of ore from the open
    pit in stockpile waiting to be crushed at the end of the year.
    Optimization of the various operating parameters of the crusher was
    underway in order to reach a steady state of production at design
    capacity and to achieve the ultimate size reduction of ore to 100% minus
    3/8'.

--  By December 31, the heap leach pad held an estimated 336,500 tonnes of
    ore containing approximately 360,000 ounces of silver and 6,900 ounces
    of gold that were under leach.

--  On September 9, 2010, the Company poured its first dore bar. As of
    December 31, 2010, 54,886 ounces of silver and 2,140 ounces of gold were
    produced as dore with a significant amount of silver and gold still in
    solution for processing and recovery. The Company sold 27,675 ounces of
    silver and 933 ounces of gold for gross proceeds of approximately
    US$1,538,000. The Company delivered 187 ounces of gold under its gold
    stream contract with Sandstorm and delivered 746 ounces under the gold
    price protection program with Macquarie Bank.

--  Average cost per ounce silver equivalent (55:1 Ag:Au) during start up in
    2010 was US$18.40 and cost per tonne of ore processed was US$13. Since
    the mine is currently in the commissioning phase, these costs are not
    representative of average commercial production projections.

Production and Commissioning Activities from January 1 to March 31, 2011

--  Approximately 220,000 tonnes of ore were crushed from the open pit at a
    strip ratio of waste to ore of approximately 3:1. Mining of the lower
    grade material was completed and the lower grade stock pile was
    processed. The high grade ore (average quarterly grade of 1.21 gpt Au
    and 39.3 gpt Ag) of the Main zone is now being mined and will provide
    the bulk of the ore to be mined in 2011. Crusher throughput averaged
    2,428 tonnes per day which is nominally below the design throughput
    capacity of 2,500 tpd. Optimization of the various operating parameters
    of the crusher was completed or underway in order to reach a steady
    state of production at design capacity.

--  Currently, the heap leach pad holds an estimated total of 555,000 tonnes
    of ore containing approximately 597,500 ounces of silver and 14,940
    ounces of gold that are under leach. In the first 90 days of the leach
    cycle for ore on the pad, recovery was estimated at 25 to 30% recovery
    for gold and 10 to 15% recovery for silver. The first ore placed on the
    pad has been under leach for approximately 200 days with estimated total
    recoveries of 35 to 45% of the gold and 20 to 30% of the silver. The
    optimum recoveries of 65 to 70% gold and 35 to 40% silver predicted by
    the design metallurgical test work appear to be achievable, but final
    leaching times may extend beyond the 300 day, test work leach cycle.

--  The Merrill Crowe recovery unit, refinery and on-site lab were all
    performing well. Optimization of cyanide concentrations, solution
    volumes and heap Ph is underway. Steady state production at design
    capacities will be dependent on sufficient tonnages and grade of ore on
    the pads to accommodate the required solution volumes.

--  During the 3 month period ended March 31, 64,712 ounces of silver and
    2,152 ounces of gold were produced as dore with a significant amount of
    silver and gold still in solution for processing and recovery. The
    Company sold 57,390 ounces of silver and 2,333 ounces of gold for gross
    proceeds of approximately US$3,810,000. The Company delivered 467 ounces
    of gold under its gold stream contract with Sandstorm and delivered
    1,866 ounces under the gold price protection program with Macquarie
    Bank. Project to date is cash positive accounting for budgeted work
    capital, operating costs and gross proceeds.

--  Average cost per ounce silver equivalent (55:1 Ag:Au) during the first
    quarter of 2011 was US$11.30 and cost per tonne of ore processed was
    US$12.70 which is within range of the operations budget. Since the mine
    is currently in the commissioning phase, these costs are not
    representative of average commercial production projections.

--  To date, no lost time accidents have occurred since construction started
    in October 2009 with over 450,000 hours worked.

J. Scott Drever, President stated; 'We are certainly pleased at this time as to how the commissioning phase for the Santa Elena mine is progressing. We are beginning to see the high grade ore of the Main Zone being stacked on the pads. Initial sales of our silver and gold will offset the operating costs during this start up phase and will set the stage for early, free cash flow that will be utilized to implement the Company's strategy for corporate growth.'
