SilverCrest Intercepts 10.1 Metres of 6.53 gpt Gold and 218.7 gpt Silver at Santa Elena, Northern Mexico

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 19, 2007) - SilverCrest Mines Inc. (TSX VENTURE:SVL) (SVL, the "Company") is pleased to report assay results for the next 5 drill holes of an ongoing Phase II 40 drill hole program at its Santa Elena Project located in Northern Mexico. The Santa Elena Project is located approximately 150 kilometres northeast of Hermosillo, Sonora, Mexico and is easily accessible with excellent local infrastructure. The Company has the right to acquire a 100% interest in the property.

These 5 core holes (to view the attached drill plan for hole locations please click on the following link: http://www.ccnmatthews.com/docs/SilverCrestMap.pdf) are part of the current program to in-fill and expand the current reported resources for the project. Of this series of holes, the most notable near-surface intercepts were encountered in holes SE07-22 and SE07-23. Drill hole SE07-22 intercepted 12.85 metres (42.15 feet) grading 4.92 gpt gold (0.143 opt) and 205.2 gpt silver (5.98 opt) and hole SE07-23 10.10 metres (33.13 feet) grading 6.53 gpt gold (0.190 opt) and 218.7 gpt silver (6.37 opt). The results of the first 2 drill holes for Phase II were announced in a press release dated September 6, 2007.

The results for this series of core holes at Santa Elena are as follows:

Hole number SE07-26 was lost due to down-hole problems. This hole location was re-drilled by SE07-35 which intercepted a mineralized zone of approximately 20 metres for which assay results are pending. A total of 17 holes of the Phase II program have been completed to date.

For this series of holes the estimated true width of the mineralized zone ranges from 6.75 to 12.85 metres and averages 9.67 metres (31.7 feet) grading an estimated 7.87 gpt (0.229 opt) gold equivalent. This higher grade portion of the Main Zone is present from surface to a vertical depth of approximately 100 metres and is expected to fall within the limits of the proposed open pit. These drill holes are in-fill and expansion holes to the east of the main area of reported resources. The grades encountered in these five holes are up to twice the grades previously encountered by limited drilling in this location. Once drilling is complete, a new resource will be estimated and should result in upgrading most of this area from inferred to indicated resources.

All samples are being analyzed at ALS-Chemex in Hermosillo, Mexico and North Vancouver, BC, Canada.

The dimensions of the mineralized zone are now estimated at 800 metres in strike length, 300 metres down dip, and a width ranging from 5 to 30 metres with an expected average of 15 metres in true width. The deposit currently remains open to the north (Footwall Zone), to the east and to depth. All of which will be further tested with the remaining holes of the Phase II drill program.

J. Scott Drever, President, stated; "We are certainly encouraged by the results of these latest holes at Santa Elena. We currently have two drills operating and the results of the program continue to exceed our expectations as the size of the deposit continues to grow. Our understanding of the nature and extent of the mineralization is improving and we have been able to successfully anticipate the most likely areas for resource expansion. This Phase II drill program will provide a basis for a resource estimation update. We are focused on completing our pre-feasibility study and making a production decision for an open pit heap leach operation before year end. If higher grade intercepts continue to be encountered and sufficient resources are defined, we will consider the viability of a conventional milling operation as a second phase of development to extend the project's potential mine life."
