Exploration Update for the Athabasca Basin
======================================================================

Vancouver, BC - Triex Minerals Corporation (TXM-TSX.V) ("Triex")
continues to advance its diverse portfolio of properties in the
Athabasca Basin, and is pleased to announce that drilling is underway
at the Pasfield Lake property, along with a concurrent program of
prospecting and ground geophysical surveys at the near-by Stony Road
property. At Cochrane River, a summer program of early-stage target
delineation work was completed in August, and at Mann Lake, drilling is
planned for November, following completion of the Pasfield program.
Property location maps can be viewed at the company's website at
www.triexminerals.com.

Pasfield Lake Property

Drilling has commenced at Pasfield Lake, located in the eastern
Athabasca Basin in northern Saskatchewan. The Property is 35
kilometres south of the road that connects Points North and Stony
Rapids, and 60 kilometres northwest of the Cigar Lake Mine, the second
largest high-grade uranium deposit in the world.

A fence of four holes is planned across the regional structure that
bounds the western margin of an uplifted block of basement rock. The
block is roughly eight kilometres across as defined by previous
airborne and ground geophysical surveys. It was confirmed by
first-pass drilling in the spring of 2007 when basement rocks of
granite gneiss and graphitic metapelite were intersected at 300 metre
depth, compared to depths of 900 metres and greater elsewhere in the
region (see news release dated May 1st, 2007). All drill holes will be
probed using a Mount Sopris 2PGA-1000 down-hole poly-gamma probe.
Geochemical samples of core will be processed at the Saskatchewan
Research Council laboratories in Saskatoon, Saskatchewan.

Continued drilling is planned for the upcoming 2008 winter drill season
starting next January.

Triex has the right to acquire an 80% interest in the Pasfield Lake
property from Thelon Ventures Ltd. Triex currently has a 60% interest
in the Property, and is the Operator. The property consists of 16
claims covering a total area of 66,811 hectares.

Stony Road Property

A surface program of geophysics and geochemistry will be done on the
Stony Road property during the next six weeks, concurrent with drilling
at Pasfield Lake. Crews will be based out of the Pasfield Lake camp
located some 40 kilometres to the southwest of the property.

The Stony Road property is located on the northern extension of Highway
905 in the northeastern part of the Athabasca Basin of northern
Saskatchewan. The property is approximately 75 kilometres northwest of
operating uranium mines at McClean Lake and Rabbit Lake.

EM Pulse Geophysics has been contracted to complete an
audiomagnetotelluric geophysical survey (AMT) on four transect lines
across the property. Concurrent till sampling and prospecting will
augment the AMT survey. This program will concentrate on two main
targets identified by an airborne MEGATEM II survey (magnetics and EM)
completed in 2006, and a 3,158 line-kilometre 3-D Full Tensor gravity
gradient airborne survey completed in May 2007.

First pass drill testing of at least one of the targets is anticipated
for the upcoming 2008 winter drill season starting next January.

Triex has the right to acquire a 70% interest in the Stony Road
property from Magnum Uranium Corp. The property consists of 15
contiguous mineral claims covering a total area of 73,996 hectares.
Triex is the Operator.

Mann Lake Property

A six week Diamond drill program is planned for the Mann Lake property
starting in November 2007. This program will follow up on pervasive
clay alteration identified in Athabasca Group sandstone for up to 90
metres above the unconformity in Hole MN06-002 completed last fall.
Hole MN06-002 is located on an east-west structure which is defined by
a ground-based gravity survey and is also evident as a cross-cutting
feature on a high resolution, airborne magnetic and EM survey. Four
holes are planned for a total of 3,000-3,500 metres and will test in
more detail the mineral potential of the structure.

The Mann Lake property is located in the eastern Athabasca Basin in
northern Saskatchewan. It is approximately 25 kilometres southwest of
the McArthur River Mine, the largest high-grade uranium deposit in the
world, and approximately 15 kilometres to the northeast of Cameco
Corporation's recently discovered Millennium Deposit. The Mann Lake
area is being actively explored. Cameco Corporation continues to
explore on their property immediately adjacent to the Mann Lake
property, following up on basement-hosted uranium mineralization
discovered during its 2006 summer drilling season.

Triex has the option to earn up to a 70% interest in the Mann Lake
Property from Consolidated Abaddon Resources Inc. The property consists
of one claim covering 3,473 hectares. Triex currently owns 51% and is
the Operator.

Cochrane River Property

The Property is near the northeastern edge of the Athabasca Basin, in
basement rocks approximately 80 kilometres northeast of Cameco
Corporation's Eagle Point Mine. It is within the Wollaston-Mudjatic
magnetic low transition zone, along which all of the major uranium
deposits in the eastern Athabasca Basin occur.

A four week surface program of mapping, prospecting and boulder and
till geochemistry was completed in August. This work will refine
targets in four key areas that have been selected on the basis of
previously completed work, including: high resolution airborne EM and
magnetic surveys; ground resistivity surveys; an extensive lake
sediment survey, and; a regional structural analysis based on the
compilation of all available regional and property-scale geologic maps
and mineral occurrences, and remotely sensed data sets (see News
Release dated April 25, 2007).

Drill targets will be evaluated, and prioritized, later this fall once
all analytical results are received from a total of 606 rock and till
samples that have been sent to the Saskatchewan Research Council
laboratories. First pass drilling is anticipated for the first or
second quarter of 2008.

Triex has the option to earn up to a 70% interest in the Cochrane River
property from Uranerz Energy Corporation. The property consists of
seven mineral claims covering 28,012 hectares. Triex is the Operator.
