SilverCrest's Santa Elena Mine Expansion Continues on Schedule

VANCOUVER, BRITISH COLUMBIA--(Marketwire -07/06/12)- SilverCrest Mines Inc. (SVL.V)(STVZF) (the "Company") is pleased to announce an update on activities for the Santa Elena Mine Expansion Plan and the ongoing Phase II La Joya drill program in Mexico. The Santa Elena Mine expansion remains on schedule, targeting a 100% increase in metal production commencing in 2014. Resource definition drilling and extensive metallurgical test work continues at La Joya with an anticipated Q4, 2012 resource update. The most significant activities are outlined below. For more information and to view photos and videos, please visit the Company's website at www.silvercrestmines.com.

Santa Elena Expansion Plan

--  GR Engineering Services (GRES) of Brisbane, Australia is completing the
    design and engineering with respect to the proposed 3,000 tonne per day
    CCD processing plant. Construction is scheduled to commence in Q4, 2012.
    Initial construction priorities include earthworks, pouring foundations
    and tank fabrication. Detailed engineering for the entire facility
    should be completed by Q1, 2013 with a target to begin milling ore from
    the open pit by January 2014.
--  Long lead time equipment for the new processing plant is currently being
    sourced either through purchase of used equipment and/or procurement of
    new equipment which is being funded from the Company's treasury.
--  Underground decline work continues with approximately 470 metres of the
    main ramp driven to date. The total underground development budgeted for
    2012 is approximately 1500 metres. This 4.5 x 4.0 metre production
    decline ramp will provide access to underground resources with an
    anticipated initial production rate of 1,000 tonnes per day starting in
    mid-2014.
--  The leach pad expansion is well advanced with completion expected in
    July. This pad expansion will provide a further 2 years of capacity for
    open pit heap leach material. Once the new processing plant is
    operational, use of the leach pads will be discontinued.
--  Gold and silver metals inventory remaining on the leach pads is
    currently being assessed as part of the mill feed for the Expansion
    Plan. Based on in-pit grade control, crusher composites and produced
    metals to date, approximately 1.9 million tonnes containing significant
    residual gold and silver ounces exists on the leach pad. Based on the
    current mine schedule, approximately 4 million tonnes of heap leached
    material may be available for reprocessing once the CCD processing plant
    is constructed. This inventory and amenability for recovery in the
    proposed processing plant will be addressed in the upcoming Expansion
    Plan Pre-Feasibility Study ("PFS"). The Company cautions that the
    potential quantities reported above are conceptual in nature and there
    has been insufficient work to date to define a NI 43-101 compliant
    resource.
--  A shallow 13 hole in pit drill program to better define tonnages and
    grade of the lower part of the planned open pit was completed in June.
    Results confirm the high grade nature of mineralization which shows up
    to 6.2 gpt Au and 102.7 gpt Ag over 16 metres. A new Gemcom block model
    is being constructed to augment the Santa Elena Life-of-Mine-Plan and
    refine projected future cash flows.
--  Surface drilling of the Santa Elena Main Zone is underway to further
    delineate underground Resources for conversion to Reserves based on
    completion of the Expansion Plan PFS anticipated by year end. Eighteen
    proposed holes are currently being drilled.
--  The Cruz de Mayo Project is a component of the Santa Elena Expansion
    Plan and work is ongoing to complete a PFS in Q3, 2012. An additional 6
    holes are to be drilled in July to further delineate Resources for
    conversion to Reserves.

La Joya Exploration

--  Phase II core drilling with two drill rigs continues to expand the known
    mineralized zones. Initial holes in this program have expanded
    mineralization to the north and east while more recent drilling has
    tested favorable areas to the south and west. To date, 40 of the 60 core
    holes planned for the Phase II program have been completed with an
    additional 20 reverse circulation holes to be completed upon rig
    availability. Assay results for the next 10 to 15 holes are being
    compiled and expected to be released later this month.
--  A new resource estimate for La Joya is anticipated in Q4 2012 with a
    target to increase the current resource of plus 100 million ounce silver
    equivalent (Ag-Cu-Au) by 50 to 100%. Please refer to February 21, 2012
    Technical Report filed on SEDAR.
--  Results to date from drilling at La Joya suggest that there is
    significant mineralization containing tungsten, molybdenum, tin, lead
    and zinc that may be by-products to the dominant silver-copper-gold
    mineralization. Further drill results and the subsequent resource update
    should assist with delineating this potential.
--  Acquisition of data generated from a historical airborne geophysical
    survey over an estimated 1400 square kilometre area including La Joya
    has been completed. This data was reprocessed by Fugro Airborne
    Geophysics of Ottawa, Canada with 25 additional magnetic-gravity-IP
    targets defined using La Joya geophysical signatures as guidelines. The
    Company is currently prioritizing these targets for further exploration
    work with plans to drill a number of the highest priority targets later
    this year.
--  To accommodate the identification of the new targets in the area, the
    Company has expanded its land package at La Joya to a total of 10,656
    hectares.

J. Scott Drever, President stated; "We are certainly pleased as to how the various components of the Santa Elena Expansion Plan to double our production and the exploration of the La Joya project are progressing. Most importantly, as we anticipated, the work is being funded largely from operational cash flow of approximately $2.5 million per month leaving our treasury of $35 million intact for the larger capital items associated with the mill facilities. This planned strategy insulates the Company from the need to finance during the current market conditions."
