======================================================================

Vancouver, BC - Triex Minerals Corporation (TXM-TSX.V) ("Triex") and
Pitchstone Exploration Ltd. (PXP-TSX.V) (collectively "the Joint
Venture") are pleased to announce the successful acquisition of those
claims on the Mountain Lake, Dismal Lakes and Kendall River properties
which are under option in the Hornby Bay Basin, Nunavut.

Location maps for the properties are available on the Company's website
(www.triexminerals.com). The properties are in the proximity of the
Mountain Lake uranium deposit located 100 kilometres southwest of the
coastal community of Kugluktuk in western Nunavut, northern Canada.

Pursuant to an Option to Purchase Agreement dated July 22, 2006 with
Aramis Ventures Inc. (see August 2, 2006 News Release) the Joint
Venture has successfully purchased 100% ownership, subject only to a
royalty, of 4 claims forming the Kendall River property in the Hornby
Basin covering a total of 4,180 hectares. Surface work on this
property in 2006 and 2007 refined targets related to a field of
radioactive boulders discovered in the 1970's. Future work will focus
on drill-testing the target area.

Pursuant to an Option to Purchase Agreement dated July 31, 2006 with
Ur-Energy Inc. (see April 26, 2006 News Release) the Joint Venture has
successfully purchased 100% ownership, subject only to a royalty, of 58
claims (52,464 hectares) forming part of the Dismal Lakes and Mountain
Lake properties. Pursuant to an Option to Purchase Agreement dated
July 31, 2006 with Patrician Diamonds Inc. (see April 26, 2006 News
Release) the Joint Venture has successfully purchased 100% ownership,
subject only to a royalty, of 10 additional claims (7,295 hectares)
forming part of the Dismal Lakes property.

Surface work in 2006 and 2007 on the Joint Venture's collective Hornby
Bay Basin properties has delineated numerous targets, with some data
collected from the western part of the Mountain Lake claim block in
2007 still pending. Drilling by the Joint Venture to this point has
focused on the Mountain Lake Deposit; future work will focus on testing
regional targets.
