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

MONTREAL, QUEBEC, Aug 26, 2010 (MARKETWIRE via COMTEX News Network) --

MatamecExplorations Inc. ("Matamec" or the "Company" - TSX VENTURE:MAT) ispleased to announce that it has stripped and channel sampled theSurprise showing, located in the eastern part of its rareearths-yttrium-zirconium Zeus property (see Figure 1).

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

2010 work on the Surprise showingincluded mechanical stripping, geological mapping of the outcrop (seeFigure 2) and collection of 14-meters of channel samples. The tablebelow lists analysis results for all 17 channel samples, with a bestinterval of 2m @ 5.3% TREO, 73% of HeavyREO + Y2O3/TREO, 3.6% ZrO2 and3.9% 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 notedthat samples 10, 11, 19, and 20 were collected outside the mineralizedzone, to provide data on the unmineralized wall rocks, and are notincluded in the quoted averages (see Figure 2). This showing isconsidered open laterally and at depth.

AndreGauthier, President of Matamec, underlines that "the channel samplingon the Surprise showing proves that the very high ratio of heavy rareearths + yttrium observed on the boulder train was also found in localbedrock, and that high grade niobium is now a recognized factor in thissector of the property."

This is the second set of resultsreleased from Matamec's 2010 exploration campaign on its rareearths-yttrium-zirconium Zeus property, which covers much of the KipawaAlkalic Complex. The 2010 campaign, which ran from May to July 2010,concentrated on the Surprise, TH and Falaises showings and ended with a2000m drilling campaign on the Kipawa deposit. Once all results arereceived, hand samples of the showings will be examined by AnthonyMariano, PhD, who will identify the mineral species containing the rareearths, yttrium, zirconium, niobium and tantalum values.

AlexKnox, geologist (P. Geol), and Aline Leclerc, geologist (OGQ) andVice-President Exploration of Matamec, are qualified persons for theZeus Project. As qualified persons, they have supervised the preparationof the scientific and technical information for the Zeus property andverified the data in this press release.

About Matamec

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

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