      Athabasca Basin Winter Drill Programs Complete
=======================================================================

Vancouver, BC - Triex Minerals Corporation (TXM-TSX.V) (the "Company")
is pleased to announce that it has recently completed the winter drill
program on the Pasfield Lake property in the eastern Athabasca Basin,
Saskatchewan.

Property details, including ownership, location maps and results from
previous programs, are available on the Company's website at
www.triexminerals.com.

Two vertical holes were completed on the property, for a total of 2,116
metres. Both holes targeted the trace of the regional Cable Bay shear
zone east of the lake, and east of the basement uplift block discovered
under the central part of the lake during 2007 drill programs. Drill
targets were the integration of surface geochemical anomalies with
geophysical features, including basement conductors, gravity lows and
changes in near-surface resistivity. Hole PF09-007 intersected the
unconformity at 906 m, the "regional" depth of basement based on
historic drill holes northwest of the property.

This drilling confirms the presence of a major regional shear zone east
of the lake, and of hydrothermal fluids and extensive alteration along
the structure. This drilling also confirms the complexity of the graben
structures between the shear zone and the margin of the eight kilometre
across basement uplift block under the lake itself. Further drilling is
required to adequately test for uranium along the margins of the uplift
block, and in the prospective but complex graben areas, especially
where shallow basement is indicated by AMT geophysical surveys.

In Drill Hole PF09-007, iron staining and spotted hematite alteration
was throughout Athabasca Group sandstone (see photo on the Company's
website). Strong radioactivity (5 times background, and up to 600 cps)
was measured over an extensive width (40 metres) immediately above the
unconformity. More than 20 metres of pervasive chlorite alteration in
fault breccia was intersected in the basement below the unconformity.
In Drill Hole PF09-008, quartz and siderite veins, veinlets and veinlet
breccias were throughout Athabasca group sandstone cover.

The significance of these results will be evaluated once geochemical
data are in hand for uranium, and the key pathfinder elements for
unconformity-type uranium deposits. Geochemical samples of core will be
processed at the Saskatchewan Research Council Geoanalytical
Laboratories in Saskatoon. A partial digestion preparation and
fluorimetric XRF analysis will be used, with a check by total digestion
preparation and ICP analytical finish. Drill holes were radiometrically
probed using a down-hole Mount Sopris 2PGA-1000 poly-gamma probe.

The Pasfield Lake property remains a large and compelling exploration
target, encompassing a major basement uplift feature located on a major
regional shear zone, with strong surface geochemical anomalies and
strongly altered and radioactive rocks discovered in drill core on both
sides of the lake, that is, on both the eastern and western "arms" of
the Cable Bay Shear zone. More drilling is required to follow-up
results to date and adequately test the strike length of the key
structural targets on the property.
