MONTREAL, QUEBEC--(Marketwire - July 7, 2011) - Matamec Explorations Inc. ("Matamec" or the "Company") (TSX VENTURE:MAT) would like to take the opportunity to provide additional information regarding its press release of Thursday, June 30, 2011.

Infill drilling has upgraded the Kipawa Deposit resource and indicated resources have increased by 67% at a 0.2% TREO cut-off. The table below now provides the TREO cut-off grades for the Kipawa Deposit for November 2010 and June 2011. Depending on the cut-off grade applied, the recently completed definition drill program has increased the indicated resource by between 40% (cut-off of 0.5% TREO) and 67% (cut-off of 0.2% TREO) and the indicated resource now stands at between 72% and 84% of the total resource.

If we compare current resource (June 2011) with the resource of November 2010 at an equivalent cut-off:

/T/

-- It increases the volume of the REE zones inside the overall mineralized

envelope of the deposit.

-- It increases the RE Oxide content in the REO envelope (at 0.2% TREO).

-- It increases of the size of the indicated mineral resources.

/T/

RE Oxide Zones:

/T/

-- At a cut-off grade of 0.3% TREO, mineral resources in the Indicated

category show an increase from 8.3 Mt to 12.5 Mt with little change in

grade. This represents an increase of 51% in Rare Earth Oxide content.

-- More than 94% of the mineral resources grade higher than 0.2% TREO in

each category.

/T/

Matamec's metallurgical tests suggest that a 0.2% TREO cut-off could be a realistic mining scenario for this deposit. At this cut-off the current resource stands at 17,645,000 tonnes in the indicated category and 6,805,000 tonnes in the inferred category. The resources contain 76,800 tonnes total rare earths and yttrium (TREO) in the indicated category and 25,200 tonnes TREO in the inferred category. The heavy rare earths (HREO+Y) average 36% of the TREO content. The contained dysprosium increases from 1,800 tonnes to 2,800 tonnes in the indicated category.
