SilverCrest Announces Positive La Joya Preliminary Economic Assessment
Base Case Pre-Tax NPV(5%) of US$133 Million and 30% IRR for “Starter Pit”

VANCOUVER, BC - October 21, 2013 - SilverCrest Mines Inc. (“SilverCrest” or the “Company”) is pleased to announce that it has completed the Preliminary Economic Assessment (“PEA”) for its La Joya Silver Copper Gold Project (“La Joya”) located in Durango, Mexico. Summaries of the current resources used for the PEA, a preliminary Life of Mine Plan (LOMP), operating costs, capital costs and project economics are presented in tables below. A Technical Report compliant with NI43-101 is being completed by EBA Engineering Consultants, a Tetra Tech Company (EBA) with an effective date of September 23, 2013 to be filed within 45 days of this release. All currency values are presented in US$ unless otherwise specified.

N. Eric Fier, President & COO stated, "The positive results of this PEA will enable us to plan the next steps, establish achievable milestones and identify additional studies and analyses to optimize the project economics. We have engaged extensively with local communities at this early stage of the La Joya project development, emphasizing the importance of building collaborative, long term and sustainable relationships with all stakeholders”.

The PEA focuses on the first stage of La Joya development (“Starter Pit”) as a low strip, open pit with an initial 9 year life of mine plan (“LOMP”) and opportunities for expansion. This approach provides attractive economic returns using conservative metal price estimates and lower initial capital costs, which are more attractive in the current market. The conceptual open pit operation would be in conjunction with a 5,000 tonnes per day (tpd) conventional mill and flotation/leaching plant to produce a high grade silver-copper concentrate with gold credits. The Starter Pit will have a conceptual average annual production of 3.9 million silver equivalent (AgEQ)* ounces per year and approximately 5 million ounces AgEQ* per year for each of the first 4 years of operation. An expansion of the Starter Pit to include additional resources within a larger pit would then be contemplated.

The Company cautions that the PEA is preliminary in nature in that it is based on Inferred Mineral Resources which are considered too speculative geologically to have the economic considerations applied to them that would enable them to be characterized as mineral reserves, and there is no certainty that the PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

HIGHLIGHTS OF THE PRELIMINARY ECONOMIC ASSESSMENT

The PEA incorporated Base Case metal prices of $22/oz Ag, $3/lb Cu and $1200/oz Au (5 year historical average). Highlights of the Base Case economic estimates for the Starter Pit are as follows:

• Pre-tax NPV5% of $133 million and an Internal Rate of Return (“IRR”) of 30.5%
• Pre-tax NPV5% of $156 million and IRR of 34% using current metal prices of $21.93/oz Ag, $1316.25/oz Au and $3.27/lb Cu (as of 18/10/2013)
• After-tax NPV5% of $93 million and an IRR of 22%
• Payback period of approximately 2 years on initial capital
• Pre- production capital costs of $141 million including contingencies of $17 million
• Sustaining capital is estimated at $8 Million
• Cash operating costs for the first three years average $10 per ounce AgEQ* and $13 per ounce AgEq* for the 9 years Starter Pit
• Pre-tax undiscounted operating cash flow before capital expenditures totalling $342.5 million at an average of $38 million per year with the first four years averaging $60 million per year
• A 9 year LOMP with 15.5M tonnes grading 50g/t Ag, 0.33%Cu and 0.19 g/t Au
• Life of mine production of an estimated 34.8 million payable AgEQ*ounces, consisting of 19 million ounces of silver and 53 thousand ounces of gold and 93 million pounds of copper in concentrate, and
• Production of an attractive high grade silver-copper concentrate (averaging 35% Cu and 4kg/t Ag) with a gold by-product.

* Silver equivalency for the PEA includes silver, gold and copper and excludes lead, zinc, molybdenum and tungsten values. The Price Ratio for Ag:oz Au is (54.4:1), lb Cu:oz Ag is (7.3:1), both based on 5 year historic metal price trends of US$22/oz silver, US$1200/oz gold, US$3/lbs. copper. Metallurgical recoveries are incorporated in the economic analysis (see Summary of PEA parameters in table below).

PEA ECONOMIC ANALYSIS

* Silver equivalency for the PEA includes silver, gold and copper and excludes lead, zinc, molybdenum and tungsten values. Price ratio for Ag: Au is (54.4:1), Ag:Cu is (7.3:1), both based on 5 year historic metal price trends of US$22/oz silver, US$1200/oz gold, US$3/lbs. copper. Metallurgical recovery is incorporated as recoverable metal.

The PEA for the Starter Pit reports strong revenues in the initial four years of operations and a decrease in the revenues for subsequent two years due to decrease in the grades. It is anticipated that additional drilling and optimization of the mine schedule could improve these results based on the presence of high grade material in some sectors of the deposit which may ultimately be incorporated into the mine plan.
Sensitivity analyses were completed by adjusting commodity prices, the results of which are presented in the following graph.

The Starter Pit economics are more sensitive to silver and copper price, as they represent 55% and 36% of the total revenues respectively under the base case scenario. Each 10% increment in metal prices from the base case changes the pre-tax NPV by approximately $60 million and the IRR by approximately 8%.

PEA CAPITAL COSTS

EBA completed detailed cost estimates for the mine and processing plant based on preliminary vendor quotes, contract mining and similar projects recently completed in Mexico. Pre-production capital costs are estimated to total US$141 million including a $17 million contingency using an open pit mine contractor. This includes development of the project over a period of 1.5 years including initial mining for one year before start-up of operations. The La Joya property has excellent infrastructure to keep capital costs reasonable with a nearby international airport, highways, railway, main power grid and lines, several operating mines and communities with available workforce. The pre-production capital costs from the PEA are summarized below.

Provisions for $8 million of working capital and $6 million in mine closure have been made as part of the economic analyses in the PEA.

PEA STUDY PARAMETERS

The PEA has incorporated the following operational and economic parameters used in the Net Smelter Return Model (“NSR”) for the silver-copper-gold concentrate and also gold-silver dore production model from tailings leaching.

No smelter penalty charges for deleterious metals were applied to the concentrate for the PEA. The study assumes that silver copper concentrate will be shipped overseas by trucking from site to a port in Mexico which is the most used route for concentrate producers in operation near La Joya.

PROCESSING & METALLURGY

The most recent metallurgical studies indicate that a conventional flotation circuit will potentially recover a high grade silver copper concentrate with gold credits. Depending on mineralization style and conditioning applied on the ALS locked cycle flotation tests, preliminary metal recoveries to the third cleaner concentrates range from 82.7 to 86.7% Cu, 76.7 to 84.3% Ag, and 18.2 to 42.4% Au for Manto and Structure composites. A gold leaching circuit with potential to recover 90% of gold and silver from the tailings to produce metal dore has also been incorporated in the PEA.

The bulk silver copper concentrates from preliminary results produced from Manto and Structure composites show certain potentially deleterious elements for smelting such as arsenic, antimony and bismuth. Adding cyanide at cleaner flotation stages reduces the arsenic content to acceptable market limits without sacrificing copper, silver and gold recoveries. Additional test work is in progress to assess the distribution, concentration and potential reduction of antimony and bismuth.

LA JOYA RESOURCES

The La Joya mineral deposit is defined as a silver copper- gold skarn with disseminated to semi-massive sulphide (bornite –chalcopyrite) with three main ore types; Mantos, Structures and Contact Zone. The updated Mineral Resource estimations for the La Joya Project provided estimated Inferred Resources of 126.7 million tonnes grading 23.5 gpt Ag, 0.19%Cu and 0.17 gpt Au containing 198.6 million ounces of silver, 533 million pounds of copper and 95,900 ounces of gold. These resource estimates were announced by news release dated January 29, 2013 and are contained in a technical report dated March 27, 2013 titled “Updated Resource Estimate for the La Joya Property, Durango, Mexico and are the basis for the PEA.

*Silver equivalency for the resource estimation filed on March 27th, 2013 includes silver, gold and copper and excludes lead, zinc, molybdenum and tungsten values. Ag:Au is 50:1, Ag:Cu is 86:1, based on 5 year historic metal price trends ofUS$24/oz silver, US$1200/oz gold, US$3/lb copper. 100% metallurgical recovery is assumed. Classified by EBA, a Tetra Tech Company and conforms to NI 43-101 and CIM definitions for resources. All numbers are rounded. Inferred Resources have been estimated from geological evidence and limited sampling and must be treated with a lower level of confidence than Measured and Indicated Resources. Note that AgEQ calculation for resources is different than PEA economic analysis based on change in metal prices. Mineralization boundaries used in the interpretation of the geological model and resource estimate are based on a cut-off grade of 15 g/t AgEq using the metal price ratios described above.

The conceptual first stage for development of La Joya with an initial 9 year Starter Pit uses the 60g/t Ag Eq cut off Inferred Resource for Manto and Structure Zones representing mineralized zones close to the surface. The PEA conceptual open pit and economic analysis excludes the Contact Zone, Santo Nino and Cerro Coloradito resources which are included in the above table.

The Contact Zone resources, not incorporated in the PEA, contains consistent Tungsten mineralization which is currently the subject of additional studies aimed at definition of preliminary economic parameters to be integrated in future assessment of the La Joya Project.

PEA POTENTIAL PRODUCTION

The Whittle Pit analysis examined the NPV of 41 potential pits utilizing a 5,000 tpd operational capacity. The optimum pit is #31 with the highest NPV(see Table below) producing a 15.8 years LOMP, but it did not meet the criteria established for a Starter Pit with low strip ratio(less than 3:1) and reasonable capital costs. On this basis the selected pit for mine design & scheduling was Pit # 18.

*41 Optimized pit shells have been generated by keeping the parameters used for the Whittle optimization constant (Operating Costs, Metallurgical Recoveries, Pit Slope Angles and Discount Factor) and by varying the Revenue using a range of metal prices illustrated in the table above

The optimal mine scheduling incorporates, mining ore and waste in the year-1 grade optimization and stockpiling of material for reprocessing during the project life. is The production scheduling (Mill Feed Tonnes & grades) is illustrated as follows:

The 5,000 tpd processing plant will be comprised of crushing, milling and standard flotation facilities with production of a silver-copper concentrate as well as a gold-silver leaching circuit for re-treatment of tailings. The PEA adopted as a guideline a mitigation of environmental and social impact by minimizing the footprint of all proposed operational facilities in the region.

PEA OPPORTUNITIES AND FUTURE STUDIES

Several opportunities are identified that could significantly enhance the economic return outlined in the PEA, including the following:

• The current Inferred Resources at La Joya provide opportunity for significant project expansion,
• Mineralization at La Joya is open in most directions with excellent potential to further increased resources. Further infill and expansion drilling is recommended to reclassify resources at a Pre-Feasibility Study level,
• Additional and detailed metallurgical test work will be completed aiming to optimize the metallurgical flow sheet and potentially improve metal recoveries,
• Review and optimization of the mining schedule could potentially provide opportunities for reduction in waste and haulage costs which could decrease capital and operating mining costs,
• This PEA does not address the potential for recovery of several other identified potential products including tungsten, molybdenum, lead, zinc, and tin which may have significant value. Further work is recommended, and
• Several other targets have been identified on the plus 10,000 hectare concession that remain to be explored for potential new discoveries
