Matamec Scoping Study Due Beginning of Q4

MONTREAL, QUEBEC--(Marketwire - Aug. 11, 2011) - Matamec Explorations Inc. ("Matamec" or the "Company")(TSX VENTURE:MAT) has engaged the independent engineering firm Roche Ltd. from Montreal, Quebec, to complete its preliminary economic assessment study (PEA) of the HREE Kipawa Deposit located near Temiscaming in SW Quebec. The study is on schedule for publication at the beginning of the fourth quarter. Highlights from the study include:

• A NI43-101 compliant indicated and inferred resource (press releases June 30, 2011 and July 7, 2011);
• A mining development plan for an open pit, small operation mine with a low strip ratio;
• Design production of 4000-4500 tpd for 5,600 tpa of mixed REO concentrate;
• A well defined metallurgical process in two simple, low cost steps based on recent tests:
  1. 35% pre-concentration with 90% recovery (July 21, 2011);
  2. Simple direct leaching method with 88% recovery (Aug. 4, 2011).

André Gauthier, Matamec's president, says "we are fully confident that we have all the ingredients to produce a robust and positive economic study. Kipawa's outcropping, sub-horizontal deposit geometry, its proximity to infrastructure and its simple mineralogy makes it a deposit that will be easy to mine and process with competitive costs, even at lower REE prices."

Aline Leclerc, V-P Exploration (Geo.) Matamec and Robert Crépeau Eng., (Independent Consultant) are the Qualified Persons for this press release.
