SilverCrest Reports 127.4m @ 65.6 gpt Ag Eq(i) at La Joya Expands Main Mineralized Trend to Northeast and Southwest

VANCOUVER, BRITISH COLUMBIA--(Marketwire -05/07/12)- SilverCrest Mines Inc. (SVL.V)(STVZF.PK) (the "Company") is pleased to announce the results of a further 16 holes of the Phase II drill program currently underway at its La Joya Property in Durango, Mexico. The Phase II program comprises an estimated 80 holes totaling approximately 15,000 metres. Phase II drilling to date has extended the Main Mineralized Trend ("Trend") an additional 500 meters to the northwest beyond the area of the current resource of 101.9 million ounces Ag Eq.(i) (see News release dated March 20, 2012). New results show the Trend expanding an additional 200 metres to the northeast and 100 metres to southwest with the average width increasing from 500 to approximately 700 metres along a strike length of 2,500 metres (see attached figure: http://media3.marketwire.com/docs/788109_figure.pdf [7]). Please reference our website at www.silvercrestmines.com [8] for more information, photos and figures on La Joya.

J. Scott Drever, President stated: "In January we announced an initial Inferred Resource in a portion of the Trend of 57.9 million tonnes grading 28 gpt Ag, 0.18 gpt Au and 0.21% Cu and containing 101.9 million ounces Ag Equivalent(i). We have since drilled 23 holes as a part of the second phase of drilling that have successfully expanded mineralization in all lateral directions with the possible expansion of the resource along the Trend. We have begun to drill the area to the southeast of the declared resource which, based on previous historic drilling and our surface sampling results, is expected to host the most attractive mineralized portion of the Trend".

These further 16 holes have partially tested the eastern and western margins of the northern end of the Trend and have provided in-fill information within the resource area. Silver values range from 2.6 gpt to 255.7 gpt and on a silver equivalent(i) basis values range from 24.0 gpt to 445.6 gpt Ag Eq. Mineralized intervals range from 3.5 metres to 127.4 metres. True thicknesses of mineralized intercepts can be approximated from previously announced drill holes in associated areas and cross-sections. The most significant assay results are shown in the following table;

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

Holes L J DD12-40 and L J DD12-41 have identified additional mineralization along the Contact Zone which had been previously drilled and defined as mineralization near the contact of Cretaceous sediments and underlying quartz feldspar porphyry stock and dykes. The Contact Zone is exposed at surface and in this area has a northwest-southeast strike approximately one and a half kilometer long with semi-massive to massive sulfide mineralization (primarily chalcopyrite and pyrrhotite) immediately adjacent to contacts. This type of mineralization is similar to that of the nearby producing Penoles' Sabinas Mine.

Holes L JDD12-44 to 48 have identified additional mineralization in the Northeast portion of the Trend previously identified as the "Esperanza" target. This mineralization is similar to previously defined mantos, structures/stockwork and the Contact Zone although the mantos and structures appear to be fewer in number and somewhat deeper than in the central section of the Trend. Further drilling in this area is required to better define near surface mineralization.

Core samples for holes L J DD12-49 to L J DD12-52 are currently in the laboratory being analyzed. The program is currently drilling at hole L JDD12-53 located on the south central part of the Trend. Assays for the next series of holes will be reported upon receipt and compilation. Several holes contain anomalous molybdenum, tungsten, lead and zinc values over significant widths in the skarn. The significance of these associated mineral zones is being examined.

The Phase II 80 hole drill program is expected to test approximately 2.5 kilometres of the Trend that includes at least the 8 near-vertical structures/stockwork zones, 14 near-horizontally stacked mantos plus the Contact Zone adjacent to the underlying intrusive. Drilling on the southern extension of the Trend has commenced. Based on Company surface mapping, sampling and historic drill hole results, this area is thought to be potentially the highest grade area along the Trend.

The La Joya Deposit currently has estimated Inferred Resources of:

SilverCrest Mines Inc. (SVL.V)(STVZF.PK) 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.

These statements relate to analyses and other information that are based on expectations of future performance, including silver and gold production and planned work programs. Statements concerning reserves and mineral resource estimates may also constitute forward-looking statements to the extent that they involve estimates of the mineralization that will be encountered if the property is developed and, in the case of mineral reserves, such statements reflect the conclusion based on certain assumptions that the mineral deposit can be economically exploited.
