New Acquisition in Athabasca Basin
======================================================================

Vancouver, BC - Triex Minerals Corporation (TXM-TSX.V) ("Triex" or the
"Company") continues to build upon it's existing portfolio of uranium
properties in the Athabasca Basin in northern Saskatchewan, and is
pleased to provide the details for it's latest acquisition. For
property location maps, please visit the Company's website at
www.triexminerals.com.

The Company has executed an option agreement with Raytec Development
Corporation for the right to earn up to a 70% interest in two
properties, the Riverlake (Key Lake West) and Highrock (Key Lake East),
located at the southern margin of the eastern Athabasca Basin.

Staked in 2004, the properties are located on either side of the Key
Lake mine road. The Riverlake property (3 claims, 16,556 hectares)
covers a large, circular magnetic low feature with similarities to the
Pasfield Lake magnetic anomaly that the Company is currently exploring.
An Athabasca Group sandstone outlier is mapped immediately to the east
of the magnetic low feature. A V-TEM survey flown in 2007 identified
electromagnetic conductors on both the east and west margins of the
magnetic low feature. The Highrock property (4 claims; 15,206 hectares)
covers an Archean basement antiform with flanking conductors, and is
located only eight kilometres southeast of the Key Lake deposit
situated along the northern margin of the adjacent Archean basement
antiform.

Ground geophysical surveying is planned for December-January to better
define the location and geometry of airborne conductors, with follow-up
first-pass drilling to be carried out during the third quarter of 2008.
Near-surface, basement-hosted uranium mineralization is the target on
both properties.

Subject to regulatory approval, Triex will earn an initial 51% joint
venture interest in the two properties by paying $25,000 in cash,
issuing 25,000 common shares (with a restrictive 4 month hold period)
and incurring an aggregate of $1,200,000 in staged exploration
expenditures by on or before November 24, 2008. The Company can
increase its ownership interest to 70% by incurring an additional
$2,400,000 in staged exploration expenditures on or before November 24,
2011. Triex will be the operator of the exploration program.

Dr. Alan Armitage, Ph.D., P.Geo., Vice President of Exploration at
Triex, is a Qualified Person as defined by National Instrument 43-101
and is responsible for program design and quality control of
exploration undertaken by the Company in the Athabasca Basin. This
release has been reviewed by Dr. Michael Gunning, Ph.D., P.Geo.,
President of Triex and a Qualified Person as defined by National
Instrument 43-101.

Triex is a Canadian junior mineral exploration company focused on
uranium opportunities in North America. The company is working in three
proven districts, advancing nine core projects which span grass roots
reconnaissance exploration to advanced-stage resource delineation. The
2007 exploration budget is $8.7 million.
