Matamec confirms 33 metres at 1.491% TREO
Matamec Explorations Inc. ("Matamec") is pleased to announce that it confirms that they obtained 1.491% TREO (total of the rare earth oxides and yttrium) up to 33 metres by re-calculating the chemical oxide elements during the resampling of the T-1 historic trench, 68 metres long, in the West Zone of the Kipawa deposit. The Company had presented the results of this trench as well as three other historic trenches, T-3, T-11 and T-8, as chemical element results (see press releases dated June 30th and July 16th, 2009) within the framework of a new NI 43-101 resource calculation. The resource calculation was initiated in November 2008 when Matamec re-sampled, under the supervision of SGS-Geostat four (4) of thirteen (13) previously excavated trenches of which twelve (12) were sampled (excluding T-5 trench) by Unocal Canada Ltd (« Unocal ») in 1990 on the Kipawa deposit. In June 2009, SGS-Geostat produced a first independent report regarding the re-sampling of the four (4) trenches and it was appended to the NI 43-101 report of the Zeus property that Matamec filed on SEDAR July 20th, 2009. The re-sampling permitted the realisation of a first check of the historical results and knowledge of the distribution of the rare earths, previously known prior to 2009 from bulk samples from 1988. SGS-Geostat concluded that the 108 samples collected confirmed the high grade rare earths mineralization of the Kipawa deposit, particularly for cerium, dysprosium, erbium, gadolinium, lanthanum, neodymium, praseodymium, samarium and yttrium (for sampling Quality Control and selection of the most appropriate analytical method, see SGS report, appendix III of the NI 43-101 technical report). In the re-sampling program (Figure 1: Trenches and bulk sampling – Kipawa Deposit), two of these trenches tested the full width of the West Zone (Trenches T-1 and T-3), one trench tested the East Zone (Trench T-8) and the last trench (Trench T-11) tested the Central Zone between the two. This central Zone was not originally part of the 1990 historical resource calculation. It is important to note that the T-8 and T-11 trenches contain historical bulk sampling sites (samples KBS-2, KBS-3 and KBS-5), solely assayed for cerium, yttrium and zirconium. These sites could not be re-sampled in 2008, due to an irregular sampling surface (5 metres un-sampled on T-8 and 20 metres unsampled on T-11). The results of the new oxide calculations for the November 2008 re-sampling program of trenches T-1 and T-3 in the West Zone are presented in the following Table 1:Kipawa Deposit | West Zone | |||

Sampling from 12 of 13 trenches and 7 bulk samples collected by Unocal and Molycorp in 1988 and 1990 on the Kipawa deposit
Sampling from 12 of 13 trenches and 7 bulk samples collected by Unocal and Molycorp in 1988 and 1990 on the Kipawa deposit. As well as the thirty-four (34) historical drill holes that were done by Unocal in 1988 and 1990 on the Kipawa deposit, thirteen (13) trenches of 100 metres were excavated in the overburden and 12 were channel sampled in 1990 for a total of 666.5 metres sampled. Also, a total of four (4) bulk samples of approximately 350 kilo grams each and three (3) samples of approximately 20 kilo grams were blasted from these trenches. Of these seven (7) bulk samples, four (4) were sent in 1990 by Molycorp to Mountain States R&D; International for separation and lixiviation tests. Historically, the rare earths were not systematically analyzed during the drilling by Unocal in the 1988 and 1990 exploration campaigns since the main element of interest at the time was yttrium. The rare earth mineralization of the Kipawa deposit is known primarily because of the bulk sampling. Four of these samples were analyzed in 1988 for yttrium, zirconium and cerium, while the other three were analyzed in 1990 for yttrium, zirconium, and the suite of rare earths as indicated in tables 4 and 5 below:Location | Sample | Trench | Weight in kg | Y2O3% | CeO2% | Rare Earths % | ZrO2% |

Matamec is exploring for rare earth elements on the Heavy Rare Earth’s Kipawa deposit (Zeus property), located in the Kipawa Alkaline Complex in Temiscamingue, Quebec, and for significant gold deposits in the Timmins mining camp in Ontario, of which the two main targets are the Matheson JV property, with Goldcorp Canada Ltd and Goldcorp Inc, and the Montclerg property.
