MONTREAL, QUEBEC, May 10, 2010 (Marketwire) -- Matamec Explorations Inc. ("Matamec")(TSX VENTURE:MAT) is pleased to announce confirmation on the spatial continuity of the Y-REE-Zr mineralized zones of the Kipawa deposit, within its 100% owned Zeus property in Temiscamingue, Quebec. Establishing this continuity in the 700m long Central Zone, set between the historically drilled Western and Eastern Zones, was one of the major objectives of Matamec's 2009 drilling campaign. The Kipawa deposit is now known over a continuous length of 1.2 kilometres and down to a depth of 85 metres.

PRESS RELEASE HIGHLIGHTS

--  Drill holes completed by Matamec strongly suggest a remarkable
geological continuity in this deposit as well as in REE-Y-Zr and Zr-
(REE-Y) mineralized zones;

-- In all sections examined within the Central Zone, except one, the down
dip drill holes are better mineralized than those updip, strongly
suggesting that mineralization intensity increases downdip of the
currently defined deposit. Follow-up drilling in this area will start
this spring;

In order to illustrate the relationship of the mineralized zones to geology and to highlight the continuity of the Kipawa deposit, three cross sections of the typical units are presented below (http://media3.marketwire.com/docs/Mat112-Fig1_English.pdf). These sections show the relationships of the mineralization, both REE-Y-Zr and Zr-(REE-Y) to the rock types.

Section 1480E (http://media3.marketwire.com/docs/Mat112-Fig2_English.pdf) shows that the syenite gneiss is about 60 m thick. It is overlain, with a gradational contact, by unmineralized peralkaline granite. The lower limit of the syenite and associated calc-silicate rocks is the base of the Kipawa Alkalic Complex, where it is in contact with Archean-aged granitic gneiss.

In this section the uppermost REE-Y-Zr mineralized zone, the Eudialyte zone, thickens from 8.9 m true thickness in the up dip hole 90-KU-28 to 29.4 m true thickness in 09-KM-61, 70 m down dip. The mineralization is associated with mesocratic to mafic, weakly foliated peralkalic syenite gneiss

The Zr-(REE-Y) mineralized zones, especially at the top of the syenite gneiss, are continuous and thick. The zone of Zr-(REE-Y) mineralization below the Eudialyte Zone is well represented in 09-KM-61. The old Unocal up dip holes either did not cut this interval or were not completely analysed for Zr.

Section 1600 (http://media3.marketwire.com/docs/Mat112-Fig3_English.pdf), 120 m to the south-east, shows similar relationships. The hole furthest down dip, 09-KM-54, shows a considerably thicker mineralized horizon than the up dip hole 09-KM-35.

In this section, in the syenite gneiss of the mineralized Eudialyte zone, the dominant REE-bearing mineral is eudialyte. In locally occurring patches of calc-silicate rocks the dominant REE mineral is mosandrite.

This section shows that the entire width of the syenite gneiss, outside of the calc-silicate horizons, is mineralized with Zr. This Zr mineralization takes the form of eudialyte within the REE-Y-Zr zones, and slightly altered vlasovite outside of these zones.

Section 2100E (http://media3.marketwire.com/docs/Mat112-Fig4_English.pdf) is located 500 m further to the south-east, near the junction of the Central Zone with Unocal's East Zone. This section, although less thickly mineralized, again shows the continuity of the REE-Y-Zr mineralized Eudialyte Zone in this part of the deposit. Again, the up dip hole has the least thickness of REE-Y-Zr mineralization. In the two down dip holes, the mineralized Eudialyte Zone is approximately twice as thick.

In the furthest down dip hole, 09-KM-51, the upper mineralized zone contains eudialyte as the principle REE-bearing mineral, as opposed to mosandrite in the two up dip holes. This may signal a change in geological environment and that more typical thicknesses of eudialyte, as seen to the north-west, may be expected downdip in this and adjacent sections.

In Section 2100E the Zr-(REE-Y) mineralized zones are virtually continuous in the syenite gneiss. Note that the uppermost portion of hole 90-KU-10, above the REE-Y-Zr zone, was not analysed for Zr by Unocal.

These three sections, combined with all the other sections completed by Matamec, strongly suggest a remarkable geological continuity of this deposit as well as in REE-Y-Zr and Zr-(REE-Y) mineralized zones. In all sections examined within the Central Zone, except one, the down dip drill holes are better mineralized than those updip, strongly suggesting that mineralization intensity increases downdip of the currently defined deposit. Follow-up drilling in this area will start this spring;

The following table indicates the thickness of the syenite and associated rocks, including amphibolites and calc-silicate rocks in each hole drilled in 2009. The numbering sequence of the 2009 fall drill campaign began with the drill hole 09KM-35. All drill holes were drilled perpendicular to the strike and dip of the gneisses, thus the widths reported from our drill holes represent the approximate true width of the syenitic complex and its associated mineralized zones.
