Matamec Discovers 3 New TREO Showings in the Falaises Area

MONTREAL, QUEBEC--(Marketwire - Oct. 5, 2010) - Matamec Explorations Inc. ("Matamec" or the "Company")(TSX VENTURE:MAT - News) is pleased to announce that continued exploration in the Falaises area of its Zeus property has led to the discovery of three new showings: Falaises A1, Medium Falaises and Coin (best value of 2.35% TREO and 9.7% ZrO2). In addition, highly mineralized boulders have been discovered around the close-by Couleuvre showing with a best value of 34.5% TREO.




PRESS RELEASE HIGHLIGHTS
- Three new TREO showings discovered in the Falaises area : Falaises A1,
Medium Falaises and Coin with best values of 2.35% TREO and 9.7% ZrO2;
- These new showings are considered open laterally and at depth;
- Four boulders lithologically similar to the Couleuvre showing were
discovered, with an average grade of 15.8% TREO.

Andre Gauthier, president of Matamec, underlines that "the Falaises and Couleuvre showings are both located in the center of heliborne radiometric anomalies. Three similar anomalies, located north of Falaises and on the east shore of Sairs Lake, have not yet been fully explained. Taking this and recent discoveries into account, the potential for new discoveries in this sector of the property is very positive."This is the sixth set of results released from Matamec's 2010 exploration campaign on its rare earths-yttrium-zirconium Zeus property, which covers much of the Kipawa Alkalic Complex. As well as the recent discoveries at the Falaises A1, Medium Falaises and Coin showings, the 2010 campaign included work at the TH showing (see September 20th press release), Surprise showing (see August 19th, August 26th and September 2nd, 2010 press releases) and the PB-PS area, and ended with a 2115m drilling campaign on the Kipawa deposit (see September 23rd press release) with complete results yet to be announced.The Falaises showing ("Cliffs" in French) is located in the center of the Zeus rare earths-yttrium-zirconium property (see Figure 1: http://media3.marketwire.com/docs/Mat131-English-Figure%201.pdf). Falaises was discovered in 2008 following Matamec's acquisition of a confidential heliborne radiometric survey and consists of 50 m (strike length) of impure marbles located at the base of an east-west oriented gneissic cliff. The new discoveries (Table 1 and Figure 2: http://media3.marketwire.com/docs/Mat131-English-Figure%202.pdf) consist of a 60m phlogopite-amphibole marble horizon located 75m due west of the main showing (Falaises A1 showing, best values of 0.86% TREO, 17% HREO + Y2O3 over TREO and 0.12% ZrO2) and a 10m amphibolite band located 40m north-east of the main showing (Medium Falaises showing, best values of 2.35% TREO, 5% HREO + Y2O3 over TREO and 0.32% ZrO2). These new showings are considered open laterally and at depthThe Couleuvre showing ("Garter Snake" in French) is located 900m to the west and consists in a thin, decimetric, highly hematized mafic segregation band in a per-alkalic granite. Despite its small size, this showing has consistently returned high-grade rare-earth values and the four 2010 boulders are no exception to the rule (Table 1 and Figure 2: http://media3.marketwire.com/docs/Mat131-English-Figure%202.pdf) with an average of 15.8% TREO, 11% HREO + Y2O3 over TREO and 0.04% ZrO2.Lastly, the Coin showing is located 750m to the north of the Couleuvre showing. This showing is composed of very coarse-grained amphibole-phlogopite with abundant zircons. Both 2010 grab samples (Table 1 and Figure 2) are frost-heaved, but with an average value of 1.5% TREO, 14% HREO + Y2O3 over TREO and 7.33% ZrO2, they still nicely underline and expand on the original 2008 discovery grab sample. The Coin showing is covered in overburden and is therefore considered open in all directions.
