Matamec Discovers up to 6.48% TREO and 72% + HeavyREO+Y2O3/TREO on the TH Showing

MONTREAL, QUEBEC--(Marketwire - Sept. 20, 2010) - Matamec Explorations Inc. ("Matamec" or the "Company")(TSX VENTURE:MAT) is pleased to announce that continued exploration on its TH showing has lead to a significant increase of its overall size. The best reported values are 6.48% TREO, 3.32% ZrO2 and up to 72% + HeavyREO Y2O3/TREO on certain samples.

Located in the north section of the Zeus property (Figure 1), the TH showing was discovered in 2008 following the acquisition of an unpublished helicopter radiometric survey. The showing consists of a series of granitoid gneiss outcrops oriented north-south, all enriched in rare earths, yttrium and zirconium. In addition, the showing is located within a soil anomaly measuring more than 700m north-south by 200m east-west.

Samples collected during the 2010 campaign underscore the significant enrichment of this showing (Table 1 and Figure 2). Traverses outside the main 2008 showing area also led to the discovery of two new sub-outcropping areas enriched in rare earths-yttrium-zirconium, adding more than 300m to the showing's north-east extension (Figure 2).

The 2010 campaign also included mechanical stripping of the main TH outcrops and collection of 50 meters of channel samples. The table below lists the best channel samples obtained in 2010, with a maximum of 1.19% TREO, 26% HeavyREO+ Y2O3/TREO and 1.18% ZrO2 over 1.9 meters (see Figure 3 for sample locations). This showing is considered open laterally and at depth.

Andre Gauthier, president of Matamec, underlines that "while less spectacular than the Surprise showing, the TH showing does cover a large surface area. There is therefore a significant probability of finding an important volume of potentially economic mineralization in this spot."

This is the fourth 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 TH showing, the 2010 campaign included the Surprise showing (see August 19th, August 26th and September 2nd, 2010 press releases) and the Falaises showing and ended with a 2000m drilling campaign on the Kipawa deposit. Once all results are received, hand samples of the showings will be examined by Anthony Mariano, PhD, who will identify the mineral species containing the rare earths, yttrium, zirconium, niobium and tantalum values.

Alex Knox, geologist (P. Geol), and Aline Leclerc, geologist (OGQ) and Vice-President Exploration of Matamec, are qualified persons for the Zeus Project. As qualified persons, they have supervised the preparation of the scientific and technical information for the Zeus property and verified the data in this press release.

About Matamec

Matamec explores for significant gold deposits in the Timmins mining camp in Ontario of which the Matheson JV property with Goldcorp Canada Ltd. and Goldcorp Inc. is the main target. In Quebec. the Company explores for precious and base metals on its Sakami, Valmont and Vulcain properties. As well, Matamec is exploring for gold together with Northern Superior Resources Inc. on its Lepérance/Wachigabau property.

Concurrently with the above mentioned exploration programs, Matamec's Quebec Tansim property is also being explored for rare metals such as lithium, tantalum and niobium.
