SilverCrest Reports New Silver Discovery at Cruz de Mayo, Mexico

VANCOUVER, B.C. May 24, 2007 � SilverCrest Mines Inc. (the �Company�) is pleased to report assay results for an additional 8 reverse circulation (RC) drill holes and the re-sampling assay results for 3 previously reported core drill holes at its Cruz de Mayo Project in northern Mexico. These results establish the continuity and grade of a silver mineralized zone that is now considered to be the discovery of a significant new silver deposit. The Cruz de Mayo Project is located approximately 180 kilometres northeast of Hermosillo, Sonora, Mexico and is easily accessible with excellent local infrastructure. The Company owns a 100% interest in 434 hectares and has a contract to purchase an additional 18 hectare concession.

Core Drill Holes

Results shown below from the re-sampling and analyses of the core hole CM05-02 define it as the �Discovery Hole� which intersected 58.9 metres (193.3 feet) grading 110.9 gpt (3.23 opt) silver. Hole CM05-02 was drilled vertically and hole CM05-03 was drilled from the same drill pad at 45 degrees to the southwest. Hole CM08-02 was located approximately 200 metres to the southwest of the Discovery Hole and was drilled at 45 degrees to the east (See attached drill hole plan and cross section).

These holes confirm a broad, lower grade silver zone generally 26 to 59 metres (86 to 193 feet) thick, with grades ranging from 77 gpt to 111 gpt (2 to 3 opt) silver and multiple, narrower, higher grade zones ranging from 489 gpt to 967 gpt (14.3 to 28.2 opt) silver. Core drill holes CM05-01, CM06-04 to CM06-07 and CM06-9 to CM06-23 were reported in previous press releases that are available on SEDAR (www.sedar.com) or our website www.silvercrestmines.com

Reverse Circulation Drill Holes

Step out RC drilling on approximately 100 to 150 metre centres from the Discovery Hole has consistently intersected significant silver mineralization including hole CMRC07-32 with 13.5 metres (44.3 feet) grading 167.7 gpt (4.9 opt) silver and hole CMRC07-33 with 30.5 metres (100.0 feet) grading 56 gpt (1.6 opt) silver (see attached cross section AA′). Within the broader mineralized zone of these significant intercepts, high grade intersections of 7.5 metres (24.6 feet) grading 417.4 gpt (12.2 opt) silver and 1.5 metres (4.9 feet) grading 1370 gpt (40.0 opt) silver were encountered in holes CMR06-32 and CMR06-35 respectively.

Holes CMR07-24 to CMR07-27 were reported in a prior press release dated March 7, 2007. The remaining 15 RC drill holes will be reported as the results are compiled and interpretations are made.� Holes CMRC07-29 and 30 were drilled outside the mineralized zone and showed no significant results. It should be noted that holes CMR07-33, CMR07-34 and CMR07-35 all ended in the mineralized zone with silver values greater than 34 gpt (1.0 opt) silver. Gold results are pending. Previous gold analysis shows 0.3 to 0.7 gpt gold within the higher grade areas of mineralization. All analyses were completed by ALS-Chemex in Hermosillo, Mexico and North Vancouver, BC.

The Company completed three initial core holes in late 2005 to test the possible extension of a small historical silver resource identified in the 1970�s. The Company followed up with a 20 core drill program in early 2006 and a more recent RC drilling program of 27 holes commencing in January, 2007. While good definition of the geology and oxidized zones have been made from logging of the drill core and samples, delays in receipt of analytical results from the labs for both drill programs have hampered, until now, a comprehensive interpretation of silver grades and continuity. With all of the re-sampling results of the core holes in hand and approximately 45% of the RC results compiled, the silver grades can now be related to the geology and more confidence can be placed on the interpretation of nature and style of mineralization.

The oxidized stockwork zone that contains the silver mineralization has been �drill-defined� over a total strike length of approximately 2.5 kilometres. Approximately 800 metres of this length have been tested with detailed drilling while the remainder has been tested with widely spaced holes. The drill area will be the subject of a Technical Report that will provide a NI 43-101 compliant resource estimate. The favorable host for stockwork silver mineralization is a ryholite bed which dips at about 25� to the southwest nearly parallel to the slope of the topography. This �dip slope� makes for potentially low strip ratios for the deposit. The deposit remains open to the northwest and will be the subject of additional work. �

Six samples have been collected for initial bottle roll metallurgical test work at the University of Sonora, Hermosillo under the direction of �Sol y Abode, Ingenieros Asociados, S.A. de C.V. of Hermosillo, Mexico.

Cruz de Mayo is located on the southeast end of a 35 kilometre long trend, the �Silver Angel Trend�. The Company controls most of the trend and continues reconnaissance exploration work to define targets similar to Cruz de Mayo. The trend has several small, grade historical silver-gold producers which required further investigation.

J. Scott Drever, President stated; �We believe the results of the RC drilling program are confirming our earlier view that Cruz de Mayo is potentially a bulk tonnage low grade silver deposit. We are well advanced with the NI 43-101 Technical Report and related computer modeling that will support a silver resource estimate. This report will also define the high grade potential of the deposit and determine whether the preliminary gold values we are seeing in the high grade zone will be a significant contributor to value. We are anxious to see the results of the bottle roll tests that will give us an indication of leachability of the lower grade material and will undoubtedly carry out metallurgical work to determine conventional recoveries of the high grade zones. In the meantime we will do the follow up work to identify other potential exploration targets in the immediate vicinity of the deposit currently being defined as well as along the Silver Angel Trend�.�
