The goal of the Kipawa mine project is to supply TTC with heavy rare earths ("HREE") for the production and marketing of hybrid and electric vehicles.

The Company has received $16,000,817 CDN toward the completion of a definitive feasibility study on the Kipawa HREE deposit. This amount includes $163,660 paid by TTC for lab test work. Matamec has managed to stay on budget for the completion of the feasibility study and will communicate the results on Wednesday, September 4th.

Under the terms of the Joint Venture Agreement ("JVA"), with the final payment received, TRECan will now acquire a 49% undivided interest in the Kipawa JV Property. Matamec received $8.5M CDN for the first 25% undivided interest on July 18, 2012. With the cumulative payment of $7,500,817 CDN, TRECan has paid Matamec for the second 24% undivided interest.

About Matamec

Matamec Explorations Inc. is a junior mining exploration company whose main focus is in developing the Kipawa HREE deposit with TRECan. Following the positive conclusion of the PEA study filed on SEDAR in March 2012 (resources that are not mineral reserves do not have demonstrated economic viability), Matamec and TRECan, JV partners, decided to move directly to the feasibility study.

In parallel, the Company is exploring more than 35 km of strike length in the Kipawa Alkalic Complex for rare earths-yttrium-zirconium-niobium-tantalum mineralization on its Zeus property. Since 2008, Matamec discovered many potential showings. Particularly, it drilled the PB-PS Zone in the fall of 2012 and identified similar Eudialyte-Mosandrite/Yttro-Tantanite/Britholite associated mineralization founded at the HREE Kipawa Deposit. This type of mineralization is presently known over 200 metres long and it opens laterally and at depth. The Company plans to drill these extensions later this year.

The Company is also exploring for gold, base metals and platinum group metals. Its gold portfolio includes the Matheson JV property located along strike and in close proximity to the Hoyle Pond Mine in the prolific mining camp of Timmins, Ontario. In Quebec, the Company is exploring for lithium and tantalum on its Tansim property and for precious and base metals on its Sakami, Valmont and Vulcain properties.
