SilverCrest Reports Positive Column Leach Test Results For El Zapote Project, El Salvador

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Dec. 14, 2006) - SilverCrest Mines Inc. (the "Company") (TSX VENTURE:SVL)(FWB:CW5) is pleased to report on the column-percolation test work that has been completed with respect to the Company's 100% owned El Zapote Project in El Salvador. The metallurgical testing is a continuation of feasibility related work designed to optimize process parameters and to permit comparison of a heap leach operation and a conventional mill facility. The heap leach alternative is being considered as a way to reduce capital and operating costs and shorten the time required to achieve initial production.

As a follow-up to the positive silver recovery results from bottle roll tests completed earlier in 2006, column-percolation test work on the oxide materials from El Zapote's Cerro Colorado III deposit was completed. This work was undertaken by Sol & Adobe Ingenieros Asociados, S.A. de C.V. in association with the University of Sonora, Hermosillo, Mexico and consisted of two column tests using minus 3/4 inch and a re-crush to minus 1/4 inch material which was then subjected to a 112 day test period. Final test results from this work are presented below and show a potential heap leach recovery of 50 to 55% for silver and over 90% for gold:

Cyanide consumption levels will be reviewed by SGS Mineral Services of Lakefield, Ontario during planned test work on cyanide recovery and optimization of the process.

The current reported NI 43-101 compliant resources for the project, which includes resources for the Tajado deposit, are presented below.

category. Cut off grade equals 34.0 gpt Ag. Numbers are rounded.

(ii)The Tajado resource is all in the Inferred resource category.


In the event the Company decides to proceed with an initial heap leach operation, there is approximately 500,000 tons of oxide material (Measured and Indicated Resource to NI 43-101 standards) grading 203 gpt Ag (5.9 opt) and 0.26 gpt Au (0.007 opt) available at the Cerro Colorado III deposit for a potential open pit, heap leach operation with an extremely low strip ratio in the initial years of operation. An additional oxide resource of approximately 500,000 tons grading 118 gpt Ag (3.4 opt) and 0.28 gpt (0.008 opt) is present at the nearby Tajado deposit.

Preliminary metallurgical test work indicates that additional silver may be recovered from the sulphide portion of the deposits, which could entail a second phase of heap leach production. Alternatively, a decision at that time to recover the zinc resources through conventional milling could be made depending upon a number of factors, most significant of which would be the price of zinc. Substantial cash flow would be expected to be available from the initial heap leach operation that could be utilized to fund the second phase of operations.

In addition to ongoing metallurgical work at El Zapote, the permitting process for an exploitation license continues. Further environmental work is underway and exploration reconnaissance of the concession area is in progress. Analyses of the samples from a geotechnical hole (CC304-03G), drilled at Cerro Colorado III in 2005, have been completed with the assay results in the interval from 0.0 to 15.8 metres grading 1.32 gpt Au (0.038 opt Au) and 72.3 gpt Ag (2.10 opt Ag) including an interval of 1.0 metre of 11.57 gpt Au (0.337 opt Au) and 111.2 gpt Ag (3.24 opt Ag). These grades show a significant gold zone located near the surface at Cerro Colorado III. All analysis was completed at CAS Laboratories (certified lab) in Tegucigalpa, Honduras.

J. Scott Drever, President, stated; "The column test results are very encouraging for a potential, initial phase silver heap leach operation at El Zapote. Given these positive results, we will revise our current technical economic study based on this alternative process design with the view to significantly reducing capital cost requirements and accelerating the possibility of an early production decision. This revised study is slated for completion by mid - 2007."
