Matamec Intersects .926% TREO Over 29.4 Metres With 34% HeavyREO+ Y2O3/TREO and 1.19% ZirconiumO2 Over 64.9 Metres in the New Central Zone on the Kipawa Deposit
MONTREAL, QUEBEC, Mar 31, 2010 (MARKETWIRE via COMTEX News Network) --
Matamec Explorations Inc. (TSX VENTURE: MAT) ("Matamec") is pleased to announce that assay results have been received for the second group of the November-December 2009 diamond drilling program on the Central part of the rare earth-yttrium-zirconium (REE-Y-Zr) Kipawa deposit located within the Zeus property. The best preliminary results are .926% TREO (total rare earth oxides) over 29.4 metres in hole KM-61.
PRESS RELEASEHIGHLIGHTS
-- The Kipawa deposit is in competition with the lateritic superficial clay
deposits located in the Lognan/Jiangxi region of Southern China, where
95% of the global heavy rare earths and yttrium production comes from.
These deposits are 3 to 10 meters thick with grades going from .05% to
.20% TREO;
-- The mineralization and the host syenite have been traced laterally for a
length of 1.2 kilometres, on an average of 52 metres thick and are known
to a depth of 80 metres;
-- The Kipawa Deposit is presently considered open both laterally and at
depth;
-- The total of each of the ten drill holes of the second preliminary
analysis group range from .366% to 1.60% TREO over thicknesses going
from 2.8 meters to 29.4 meters. These drill hole intersections contain
27% to 48% HeavyREO + Y2O3 / TREO;
-- The total of each of the eleven drill holes of the first preliminary
analysis group range from .474% to 1.54% TREO over thicknesses going
from 2.5 meters to 17.6 meters. These drill hole intersections contain
17% to 48% HeavyREO + Y2O3 / TREO;
-- As well as REE-Y-Zr mineralization, the Kipawa deposit contains thick
zones of ZrO2 (zirconium oxides) mineralization. The total of each of
the drilling holes go up to 1.10% ZrO2 over 49.1 meters to 1.01 % ZrO2
over 67.2 meters;
-- Each of the 11 first drill hole ZrO2 mineralized zones are accompanied
with TREO values. The totals for each of the drill holes go from .243%
to .453% TREO with thicknesses going from 49.1 to 67.2 meters. These
drill hole intersections contain 27% to 36% HeavyREO + Y2O3 / TREO;
-- A REE-Y-Zr mineralized zone is present in all analysed drill holes;
-- In all but one of the drill sections in which two or more holes have
been drilled, the hole that was drilled the furthest down dip (South-
West) had the thickest and/or highest grade intersection;
-- Upon receipt of all the 2009 assay results, a new NI 43-101 resource
estimate will be completed by SGS-Geostat using the new data as well as
the historic Unocal data;
-- Mineralogical work is being supervised by Dr. A. Mariano and preliminary
metallurgical tests are being done under the auspices of L. Heymann,
P.Eng;
The total of each of the ten drill holes of the second preliminary analysis group range from .366% to 1.60% TREO over thicknesses going from 2.8 meters to 29.4 meters.

Kingsnorth of Industrial Minerals Company of Australia Pty Ltd. on their
last presentation entitled "Rare earths - balancing supply & demand" at the
20th Industrial Minerals International Congress & Exhibition on March 21-24,
2010, in Miami divided the 15 REEs in three types:
Light (or Ceric) rare earths (LREO) = La2O3 to Nd2O3.
Medium rare earths (MREO) =Sm2O3 to Gd2O3. Heavy (or Yttric) rare earths
(HREO) = Tb2O3 to Lu2O3.
----------------------------------------------------------------------------
Note : The fifteen elements which compose TREO of each drill hole will be
published when the assay results for all 33 drill holes will be received.
----------------------------------------------------------------------------
Note: these TR-Y-Zr zones are defined by a 0.1% + Y2O3 cut-off over a
minimum of 2.5 meters to conform with the historic Unocal data.
----------------------------------------------------------------------------
This brings to 21 the number of drill holes out of 31 of this program for which Matamec has received interim results. Every drill hole for which the results are known has intersected with a mineralized zone. Many of these zones contain multiple layers of REE-Y-Zr.
Moreover, the complete results are now available for the first group of drill holes (11 drill holes, see press release on March 5, 2010), most particularly for the over-limits of ZrO2. The complete results are detailed in Table 2 (see Table 1 for the location of the assays that are circled inred):

----------------------------------------------------------------------------
Note : The fifteen elements which compose TREO of each drill hole will be

----------------------------------------------------------------------------
Note: these TR-Y-Zr zones are defined by a 0.1% + Y2O3 cut-off over a
minimum of 2.5 meters to conform with the historic Unocal (1988-1990) data.
----------------------------------------------------------------------------
The total of each of the eleven drill holes of the first preliminary analysis group range from .474% to 1.54% TREO over thicknesses going from 2.5 meters to 17.6 meters. These drill hole intersections contain 17% to 48% HeavyREO + Y2O3 / TREO.
These results show that a zone of REE plus Zr mineralization is present in every hole so far analysed, confirming (1) the postulated continuity between the previously defined (by Unocal Canada Ltd, 1990) West and East Zones; (2) in all but one of the drill sections in which two or more holes have been drilled (see Figure 1), the hole that was drilled the furthest down dip (South-West) had the thickest and/or highest grade intersection. The best of the intersections in Table 1 above, that in KM 61, is located at the east end of the West Zone and is completely open at depth. These two facts strongly suggest that the mineralization is improving in the down dip direction within the recently drilled area, which significantly increases the tonnage potential of the project.
As well as REE-Y-Zr mineralization, the Kipawa deposit contains thick zones of ZrO2 (Zirconium oxides) mineralization. The total of each of the drill holes go up to 1.10% ZrO2 over 49.1 meters to 1.01 % ZrO2 over 67.2 meters. The majority of the Zr in these adjacent zones is contained in the mineral vlasovite, a potentially non-refractory Na-Zr silicate. Mineralogical work is being supervised by Dr. A. Mariano and preliminary metallurgical tests are being done under the auspices of L. Heymann, P.Eng. These two world renowned experts are members of the Strategic Committee for Rare Earths advising Matamec's Board of Directors.
Each of the ZrO2 mineralized zones of the first 11 drill holes are accompanied with TREO values. The totals for each of the drill holes go from .243% to .453% TREO with thicknesses going from 49.1 to 67.2 meters. These intersections contain 27% to 36% HeavyREO + Y2O3 / TREO. Matamec considers itself a potential global supply for REE-Y-Zr. It is in competition with the lateritic surficial clay deposits located in the Lognan/Jiangxi region of Southern China, where more than 95% of the global heavy rare earths and yttrium production comes from. These deposits are 3 to 10 meters thick with grades going from .05% to .20% TREO.
These Zr mineralization zones, which are accompanied by TREO, are present in every hole, so far analysed, as set out in the table 3 below (they are defined by an arbitrary 0.5% ZrO2 cut-off over a minimum width of 5 m, other than the total for each drill hole). Only those drill holes for which complete over limit analyses have been received are listed below:

Note: that the ZrO2 zones in the table above sometimes overlap with or

----------------------------------------------------------------------
All mineralized zones intersected to date, both REE-Zr and Zr, are interpreted to dip at about 20o to the southwest, parallel to the layering in the host peralkalic syenite gneiss. The mineralization and the host syenite have been traced laterally for a length of 1.2 kilometres. The syenite body which hosts the mineralized zones is an average of 52 metres thick and is known to a depth of 80 metres. The Kipawa Deposit is presently considered open both laterally and at depth.
Upon receipt of all the 2009 assay results, a new NI 43-101 resource estimate will be completed using the new data as well as the historic Unocal data. In terms of historic resources, the Kipawa Deposit is composed of the West Main Zone (1.26 Mt @ 0.15% Y2O3 and 0.96% ZrO2) and the East Main Zone (1.09 Mt @ 0.14% Y2O3 and 1.17% ZrO2). Please note that a qualified person has not done sufficient work to classify the historical estimates as current mineral resources, Matamec is not treating the historical estimates as current mineral resources and the historical estimates should not be relied upon.
Matamec maintains a quality control program conforming to industry best practices in the sampling and analysis of drill core. The NQ core is split, with one half kept for reference at our Val d'Or facilities. Samples were then submitted in batches containing known standards and blanks to the ALS Chemex ("ALS") preparation facility in Val d'Or where the samples are reduced to pulps and couriered to ALS in Vancouver (B.C.) for analysis. The samples were analysed by ICP-MS methods on a 2 gram sample size. The samples and core are stored in a secure location until delivered to ALS.
Alex Knox (P.Geol) and Aline Leclerc, geologist (OGQ) and Matamec's Vice-President Exploration, are Matamec's Qualified Persons for the Zeus project. As QP, they supervised the preparation of the scientific and technical information for the Zeus property and verified the data disclosed in this press release. Alex is member of the Strategic Committee for Rare Earths advising Matamec's Board of Directors.
