Archean Star Announces Completing 91.5% of Gnaweeda Option Expenditures

Archean Star Resources Inc. (TSX VENTURE:ASP) (the "Company" or "Archean")
announces that it has advised Teck Australia Pty Ltd. ("Teck") and Chalice Gold
Mines Limited, ("Chalice") that Archean has completed over 80% of the budgeted
2011-2012 Joint Venture expenditure of AUD$1,750,000 on the Gnaweeda Gold
Project ("Gnaweeda"). Under the terms of the underlying Joint Venture Agreement
between Teck and Chalice, and the current Option Agreement between Archean and
Teck, Archean is the Operator of the Joint Venture.


Chalice elected not to fund its pro-rata share of the Gnaweeda 2011 - 2012 Joint
Venture expenditure, and, pursuant to the Teck-Chalice Agreement, Chalice has
been diluted to an approximately 13.5% ownership of Gnaweeda, with the Teck
ownership percentage increasing to 86.5%.


To date Archean has spent approximately AUD$2,750,000 or 91.5% of the required
AUD$3,000,000 expenditure required to earn Teck's interest in the Gnaweeda
Property, subject to Teck having a 75% back in right. Archean now has only
AUD$250,000 of additional expenditures to incur to complete its 100% earn-in of
Teck's interest.


The approximately 170 sq km Gnaweeda Greenstone Gold Belt, which is
substantially under explored, has the potential to host similar size gold
deposits to the nearby Meekatharra gold fields that have historically produced
approximately 3.5 million ounces of gold, and has current reported resources of
approximately 3.3 million ounces of gold. Gnaweeda is located in the northeast
area of the highly prolific Murchison Greenstone Gold Belt where, historically,
over 18 million ounces of gold have reportedly been produced. Westgold Resources
recently announced a 29% increase in their resources at the Cue project in the
Murchison gold belt; from 1.9 million ounces to 2.7 million ounces.


Archean Star Resources Inc., is a junior exploration company listed on the TSX
Venture Exchange that is creating shareholder value by earning, through its
wholly owned subsidiary, Archean Star Resources Australia Pty Ltd, 100% of Teck
Australia Pty Ltd.'s ("Teck") interest, subject to a 75% back in right in such
interest to Teck, in Chalice Gold Mines Limited's Gnaweeda Gold Project in
Western Australia. Currently the Company has expended approximately AUD$2.75
million of the AUD$3 million required to earn 100% of Teck's interest in
Gnaweeda. The Company's goal is to identify and develop a one million plus ounce
gold resource at Gnaweeda.
