Hathor Exploration Limited: Economic Assessment is Underway at Roughrider

Hathor Exploration Limited (TSX:HAT) is pleased to announce that a formal
economic assessment has been started for the Roughrider Uranium Deposit at its
Midwest Northeast Property in the Athabasca Basin of northern Saskatchewan.


Hathor has initiated an independent, NI 43-101 compliant Preliminary Assessment
("PA") of the Roughrider Uranium Deposit. The PA will evaluate, in detail, the
economic viability of developing the deposit as it is currently defined, and
express the viability in the form of a net-present-value analysis (NPV). The
study will be authored by SRK Consulting (Canada) Inc. Completion is expected in
approximately four months. The first working group meeting was held June 16,
2011, and a site visit for the full working group is planned for June 27, 2011.


Environmental baseline work is being conducted in parallel with the PA.
Fieldwork began in late May, and will be ongoing throughout 2011.


A detailed working knowledge of Roughrider geological models and resources, as
announced on November 30, 2010, for the West Zone and on May 17, 2011, for the
East Zone provide the foundation for the PA. The attributes of Roughrider,
including location, size, grade, depth, recovery and ore composition are
expected to provide for a robust model; the attached previously released figures
highlight some of the key attributes.


Midwest Northeast Property

The Midwest Northeast Property is located within the main uranium-producing
eastern corridor of the Athabasca Basin. The Property comprises 3 mineral leases
covering 598 ha. Infrastructure is excellent. The Property is connected to
Highway 955 by a 6 km winter road. The property is 8.5 km north of the
infrastructure centre of Points North and the Points North commercial airport,
the main service hub for northeastern Saskatchewan. The Property is within 25 km
of operating uranium mine, mill and tailings facilities established at Rabbit
Lake and McClean Lake during the past 35 years of production in the Athabasca.


Terra Ventures Inc. owns a qualified 10% interest in the largest lease, carried
to the completion of a positive feasibility study and announcement of intent for
commercial production. Terra and Hathor recently announced (May 9, 2011) a
definitive Plan of Arrangement, which remains subject to a number of conditions
including, but not limited to, receipt of all regulatory, court and shareholder
approvals, and will result in consolidation of 100% ownership of the Roughrider
uranium deposit.
