VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov 27, 2012) - SilverCrest Mines Inc. (TSX VENTURE:SVL)(CW5.F)(NYSE Amex:SVLC)(NYSE MKT:SVLC) (the "Company") is pleased to announce the results of an additional 15 holes (LJ DD12-75 to LJ DD12-89) of the Phase II drill program nearing completion at its La Joya Property in Durango, Mexico. 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.*(see News releases dated March 20 and May 7, 2012 and attached Figure: http://media3.marketwire.com/docs/silvercrestmap1.pdf). Drilling and surface sampling has extended the Trend to approximately 2.5 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.
Five of the 15 holes reported in the tables and text below continued to test the southern extension of the Trend with the remaining 10 holes focused on the delineation of the Contact Zone and Santo Nino Target. Silver values in this series of core holes along the Trend and Contact Zone range from 3.3 gpt to 189.0 gpt. Silver equivalent based values range from 19.7 gpt to 324.1 gpt Ag Eq.* (0.57 oz/ton to 9.45 oz/ton). Mineralized intervals range from 15.2 metres to 288.7 metres. True thicknesses of mineralized intercepts can be approximated from cross sections of previously announced drill holes in the respective areas. Intercepts in holes drilled at a 45º angle are at vertical depths considerably less than implied by the core length measurements so many of the intercepts are near surface. Intercepts in holes 79, 84 and 86, presented below, are examples of near surface higher grade mineralization that may be considered in a potential starter pit. The most significant assay results for this series of holes are shown in the following tables:

Contact Zone and Santo Nino Target (W, Cu, Au)
Four additional holes were drilled on the near-surface portion of the Contact Zone which is located within the Trend boundaries but can be identified separately from the manto and structure mineralization of the Trend. The Contact Zone mineralization is located geologically and spatially below the Trend mineralization. The Contact Zone mineralization consists of skarning with stockwork veining and occurs adjacent to intrusive stock and dykes which are exposed at surface in the southern portion of the Trend. Holes intercepting the Contact Zone also contain anomalous Pb (lead), Zn (zinc), Mo (molybdenum) and Sn (tin).
Partial drilling of the Contact Zone shows consistent intercepts of wide-spread tungsten (W03), gold (Au), copper (Cu) mineralization from near surface to depths of up to approximately 300 metres vertically. All drilling to date that has intercepted intrusive(s) has also intercepted the Contact Zone over an area of approximately 2 kilometres by 1 kilometre with estimated thicknesses ranging from 10 to 200 metres and appears to conform to the contours of the underlying intrusive. A detail model of the intrusive surface has been developed from drill data to provide a guide for further definition of the Contact Zone which is considered a "potential large bulk tonnage tungsten target" and will be segregated as part of the next resource estimation due in Q4 2012.
Holes L J DD12-76, 77, 78 80, 82, and 83 were drilled to test the Santo Nino Target approximately 1 kilometre east of the Trend''s eastern boundary. Hole 82 intercepted 18.4 metres of semi-massive sulphides grading 20.1 gpt Ag, 0.04 gpt Au and 0.43% Cu. This hole encountered an extension of the massive sulphide mineralization (Santo Nino) reported in the discovery Hole L J DD12-74 which intercepted 35.2 metres grading 52.2 gpt Ag, 0.05 gpt Au, 1.6% Cu and 0.037% WO3. The mineralization is believed to be associated with a substantial east-west structure that cross cuts the width of the Trend mineralization to the west. Holes L J DD12-77, 78, and 80 were located near the Santo Nino target but were off the target and intercepted no significant values.

Near surface tungsten/molybdenum mineralization encountered in both the Contact Zone and the adjacent Coloradito target (see previous press releases) is similar in grade 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 references are from public company websites.
The Phase II drill program is essentially complete and was designed 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 which is adjacent to the underlying intrusive. Drilling on the southern extension of the Trend and Contact Zone has been completed and two of the three core drill rigs have been released. A reverse circulation drill is expected to commence drilling on exploratory targets in the area prior to month end. Based on Company surface mapping, sampling and historic drill hole results, the southern area is still believed to be potentially the highest grade area along the Trend. The Company is currently examining the potential for a potential near-surface, higher grade, low strip open pit as a conceptual "starter pit" that will be evaluated in a Preliminary Economic Assessment in 2013.
Core samples for holes L J DD12-90 to L J DD12-105 are currently being logged, sampled or are in the laboratory for analyzes. 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. Extensive metallurgical test work is underway to examine the amenability and potential metallurgical recoveries of Ag, Au, Cu, W, Mo, Sn, Zn and Pb. Metallurgical test work results will be presented in the NI43-101 Technical Report in early 2013.
The La Joya Deposit (Main Mineralized Trend) currently has estimated Inferred Resources of:
|CATEGORY**||CUT OFF GRADE (AG EQ.* GPT)||TONNES |
|AG GPT||AU GPT||CU %||CONT- |
AINED AG EQ. OZ*
* Silver equivalency includes silver, gold and copper and excludes lead, zinc, molybdenum and tungsten values. Ag:Au is 50:1, Ag:Cu is 86:1, based on 5 year historic metal price trends of US$24/oz silver, US$1200/oz gold, US$3/lb copper. 100% metallurgical recovery is assumed.
** Classified by EBA, A Tetra Tech Company and conforms to NI 43-101, 43-101CP, and CIM definitions for resources. All numbers are rounded. Inferred Resources have been estimated from geological evidence and limited sampling and must be treated with a lower level of confidence than Measured and Indicated Resources.
*** Mineralization boundaries used in the interpretation of the geological model and resource estimates are based on cutoff grades of 15 gpt Ag Eq and 30 gpt Ag Eq using the metal price ratios described above.
Please refer to the January 4, 2012 news release and to the La Joya NI 43-101 Technical Report dated February 20, 2012 for further details of the Inferred Resource estimate.
The target size of the La Joya mineralization and the potential subsequent estimated resources based on the current geologic model, drilling and sampling from the Phase II 2012 program suggests the possibility of target resources that may be 50 to 100% greater than the current resources. This potential increase in quantity of resources is conceptual in nature and insufficient exploration has been completed to define with certainty a mineral resource of this size. It is uncertain that further exploration will result in the target being delineated as a mineral resource.
