Hathor Extends Roughrider Uranium Mineralization Eastward

Hathor Exploration Limited (HAT:TSX-V) is pleased to announce assay results from drill hole MWNE-11-667, the first complete set of drill hole assays received from the ongoing 2011 winter drill program at the Company's Roughrider project in the Athabasca Basin, Saskatchewan. Some 15,000 metres are planned for the three rig program, which will continue until the end of the winter season (Figure 1).

Drill hole MWNE-11-667 has intersected significant new uranium mineralization 40 m to the east of the East Zone, as it is currently defined by 2010 drilling. The East Zone now has uranium mineralization in drill holes across 200 m. This new intersection is the most easterly mineralization discovered to date in the overall "Roughrider System" (Figure 2), and mineralization remains open to the east.

The main intersection comprises two core intervals of 16.5 m and 18.0 m of 2.14 % and 1.30 % U₃O₈ respectively, separated by 3.0 m with an average grade of < 0.01 % U₃O₈, for a composite of 1.57 % U₃O₈ over 37.5 m. Data are in Table 1 below. Important attributes include:

Visible pitchblende mineralization present over a vertical extent of 90 m (Photo 1 and 2)
Clay and hematite alteration is pervasive throughout the composite interval (Photo 3).
Mineralization is hosted entirely within basement rocks, well below unconformity regolith.
Deleterious elements such as arsenic and selenium, are low. Associated metals such as Cu and Mo are also low.

This new mineralization is deeper than the mineralization intersected to date elsewhere within the Roughrider system. As shown in the 3-D model in Figure 3, the mineralization in MWNE-11-667 represents either: 1. the down dip extension of the East Zone of Roughrider, or; 2. an entirely new zone of mineralization, separate from East Zone, with unique geometry and extent. The grade shell shown in Figure 3 for the East Zone was produced using Leapfrog 3D geological modelling software for preliminary mineralization wireframe models completed by Hathor, and currently being evaluated for a preliminary NI 43-101 mineral resource estimate for East Zone.

This new mineralization is a significant development for Roughrider: it either extends the East Zone, or it adds a third zone to the system.

Infill drilling continues along the entire length of the East Zone, between East Zone and West Zone ("the gap"), and northeast of West Zone, as shown in Figure 1). That said, drill holes planned for the 2011 winter season (Figure 1) have been reprioritized as a result of this drill hole. Detailed drilling will be done around Hole 667 for the remainder of the drill season to establish the potential for this new mineralization, and to determine its relationship to East Zone.

* All intersections are down-hole intervals. Geometry of mineral zone is not yet determined.
** All drill holes have the prefix 'MWNE-'.

Samples were analyzed for U3O8 at the Geoanalytical Laboratories of the Saskatchewan Research Council (SRC). The facilities used for the analysis operate in accordance with ISO/IEC 17025:2005 (CAN-P-4E). The samples were analyzed using ISO/IEC 17025:2005-accredited U3O8 method. The samples were analyzed for a suite of other base metal elements including nickel, cobalt, copper and lead by ICP-ES. Dry bulk density determinations will have been carried out on the drill core.

The Midwest Northeast Property is within the main uranium-producing eastern corridor of the Athabasca Basin. The Property comprises 3 claims covering 543 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 community of Points North and the Points North commercial airport, the main service hub for northeastern Saskatchewan. It is within 25 km of operating uranium mines, mills 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 claim on the Property, carried to the completion of a positive feasibility study and announcement of intent for commercial production.
