SilverCrest Reports 50m @ 151.8 gpt Ag Eq(i) at La Joya Main Mineralized Trend Continues to Expand

VANCOUVER, BRITISH COLUMBIA--(Marketwire -07/17/12)- SilverCrest Mines Inc. (SVL.V)(STVZF) (the "Company") is pleased to announce the results of an additional 11 holes of the Phase II drill program currently underway at its La Joya Property in Durango, Mexico. The Phase II program is comprised of 80 holes totaling approximately 15,000 metres. Phase II drilling reported to date has extended the Main Mineralized Trend ("Trend") beyond the area containing the current Inferred Resource of 101.9 million ounces Ag Eq.(i)(see News releases dated March 20 and May 7, 2012 and attached figures:

http://media3.marketwire.com/docs/20120717_Coloradito_La_Joya.pdf and http://media3.marketwire.com/docs/20120717_La_Joya.pdf). The drill defined Trend now extends for approximately 2 kilometres with an average width of approximately 700 metres. Please reference our website at www.silvercrestmines.com for more information, photos and figures on La Joya.

J. Scott Drever, President stated: "Since announcement of our initial resource in January of this year, we have drilled an additional 45 holes as a part of the second phase of drilling at La Joya and have now reported positive results for 33 holes. We have successfully expanded mineralization in all lateral directions along the Trend with the possible expansion of the declared resource. The most recent holes confirm our interpretation that the area to the south of the declared resource appears to host the most attractive mineralized portion of the Trend which in many instances begins at or near to surface".

The Company has completed 45 core holes to date of the planned 60 core and 20 RVC holes in the Phase II program. Three of the 11 holes reported in the tables and text below partially tested the southern extension of the Trend, one hole is an in-fill of the Phase I resource area and the remaining seven holes focused on the Coloradito target. Silver values in the holes along the Trend range from 8.5 gpt to 124.1 gpt and on a silver equivalent(i) basis values range from 25.8 gpt to 246.2 gpt Ag Eq. Mineralized intervals range from 6.8 metres to 182.0 metres. True thicknesses of mineralized intercepts can be approximated from cross sections of previously announced drill holes in associated areas. The most significant assay results are shown in the following 2 tables;

All sample analyses were completed by ALS Chemex in Zacatecas, Mexico and North Vancouver, BC, Canada.

The Phase II drill program is expected to test approximately 2.5 kilometres of the Trend which includes at least 8 near-vertical structures/stockwork zones, 14 near-horizontal, stacked mantos plus the Contact Zone that is adjacent to the underlying intrusive. Drilling on the southern extension of the Trend continues with two drill rigs and a third starting in July. A reverse circulation drill is expected to be added in due course. Based on Company surface mapping, sampling and historic drill hole results, the southern area is thought to be potentially the highest grade area along the Trend. Drill results presented in above table partially reflect this higher grade area.

Core samples for holes L J DD12-60 to L J DD12-66 are currently in the laboratory being analyzed. The Company is currently drilling at hole L JDD12-71 located on the southern part of the Trend. Assays for the next series of holes will be reported upon receipt and compilation. Several holes contain anomalous molybdenum, tungsten, tin, lead and zinc values over significant widths in the skarn. The significance of these associated mineral zones is being examined.

Seven additional holes were drilled on the Coloradito target which is a separate target one kilometre to the west of the Trend. Coloradito mineralization consists of skarning with stockwork veining. This mineralization is similar to that identified in adjacent Main Mineralized Trend with multiple intrusives doming Cretaceous sediments and subsequent skarn development. Molybdenum values appear to be higher (up to 0.6% Mo) at Coloradito compared to La Joya where copper values are higher (up to 15% Cu) which implies a different intrusive or a subsequent intrusive event with different mineralizing solutions. Coloradito holes also contain anomalous Cu, Pb, and Zn. Additional drilling will be necessary to determine the nature and extent of this potential deposit.

Previous historic drilling results for Coloradito were stated in a news release dated February 16, 2012. New drill hole assay results confirm the previously identified molybdenum and tungsten mineralization which show up to 116 metres thick grade 0.048% Mo and 0.098% WO3. Reported near surface mineralization is similar to current economic or potentially economic near surface bulk tonnage deposits such as Thompson Creek Mine, ID (0.046 to 0.081 % Mo), Endako, BC (0.030 to 0.046 % Mo) Sisson, NB (0.031% Mo, 0.094% WO3), and El Creston, Mexico (0.071% Mo, 0.06% Cu).

All sample analyses were completed by ALS Chemex in Zacatecas, Mexico and North Vancouver, BC, Canada.

Hole L J DD12-51 (Az, Dip; 45, 45) located south of the Coloradito target showed no significant results with most of the hole drilled in mostly marble with minor skarning which was targeting deeper skarn mineralization. The deeper target was not intercepted.

The La Joya Deposit (Mineral Mineralized Trend) currently has estimated Inferred Resources of:

Please refer to the January 4, 2012 news release for further details of the Inferred Resource estimate and to the La Joya NI 43-101 Technical Report dated February 20, 2012.

The Phase II drill program is anticipated to be complete in August 2012 with a subsequent revision and announcement of updated resources by Q4 2012. Extensive metallurgical test work is ongoing to review amenability and potential metallurgical recoveries of Ag, Au, Cu, W, Mo, Sn, Zn and Pb. Test work results will be presented in the next NI 43-101 Technical Report also anticipated in Q4 2012.

SilverCrest Mines Inc. (SVL.V)(STVZF) is a Mexican precious metals producer with headquarters based in Vancouver, BC. SilverCrest's flagship property is the 100%-owned Santa Elena Mine, which is located 150 km northeast of Hermosillo, near Banamichi in the State of Sonora, Mexico. The mine is a high-grade, epithermal gold and silver producer, with an estimated life of mine cash cost of US$8 per ounce of silver equivalent (55:1 Ag:Au). SilverCrest anticipates that the 2,500 tonnes per day facility should recover approximately 4,805,000 ounces of silver and 179,000 ounces of gold over the 6.5 year life of the open pit phase of the Santa Elena Mine. A three year expansion plan is underway to double metals production at the Santa Elena Mine and exploration programs are rapidly advancing the definition of a large polymetallic deposit at the La Joya property in Durango State.
