Matamec Gets an Average of 74% HeavyREO + Y2O3/TREO, 2.8% TREO and 2.1% of Nb2O5 on all Samples Analyzed From the Surprise Showing

MONTREAL, QUEBEC--(Marketwire - Aug. 26, 2010) - Matamec Explorations Inc. ("Matamec" or the "Company" - TSX VENTURE:MAT) is pleased to announce that it has stripped and channel sampled the Surprise showing, located in the eastern part of its rare earths-yttrium-zirconium Zeus property (see Figure 1).

This outcrop was discovered in September 2008 and stripped manually over 2 meters at that time. Analysis gave up to 2.3% TREO (total rare earth and yttrium oxide), 0.7% ZrO2 (zirconium oxide) and 1.1% Nb2O5 (niobium oxide). In addition, this showing lies within a large boulder train, from which six grab samples recently yielded >10.6% TREO, up to 86% HeavyREO + Y2O3/TREO and up to 7.0% Nb2O5 (see press release dated August 19th, 2010).

2010 work on the Surprise showing included mechanical stripping, geological mapping of the outcrop (see Figure 2) and collection of 14-meters of channel samples. The table below lists analysis results for all 17 channel samples, with a best interval of 2m @ 5.3% TREO, 73% of HeavyREO + Y2O3/TREO, 3.6% ZrO2 and 3.9% Nb2O5. The average ratio of mineralized samples is 2.8% TREO, 74% of HeavyREO + Y2O3/TREO, 2.3% ZrO2 and 2.1% of Nb2O5. It should be noted that samples 10, 11, 19, and 20 were collected outside the mineralized zone, to provide data on the unmineralized wall rocks, and are not included in the quoted averages (see Figure 2). This showing is considered open laterally and at depth.

Andre Gauthier, President of Matamec, underlines that "the channel sampling on the Surprise showing proves that the very high ratio of heavy rare earths + yttrium observed on the boulder train was also found in local bedrock, and that high grade niobium is now a recognized factor in this sector of the property."

This is the second 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. The 2010 campaign, which ran from May to July 2010, concentrated on the Surprise, TH and Falaises showings 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.
