Hathor Receives Final Winter Assays and Plans an Aggressive Summer Drill Program to Test the Full Potential of Roughrider East

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 29, 2010) - Hathor Exploration Limited (TSX VENTURE:HAT) is pleased to announce the final results for the 2010 winter drill program at Roughrider East. Uranium mineralization has been delineated for 100 m back towards Roughrider from the discovery hole, MWNE-09-170. Results to date outline significant potential at Roughrider East; it is open in all directions and aggressive drilling this summer will both infill areas already drilled, and test the potential extent of mineralization away from current fences.

Summary of New Results

Despite the first pass nature of drilling, uranium mineralization was intersected in all four drill fences, delineating mineralization along 100 metres of strike. Assays from mineralized samples are in Table 1 attached to this release; highlights are shown below.

- MWNE-10-624B:    44.5 m at 0.345% U3O8    40 m west of discovery (09-170)
- MWNE-10-622:     10.5 m at 0.71% U3O8     60 m west of discovery (09-170)
- MWNE-10-626A:    7.5 m at 2.54% U3O8      80 m west of discovery (09-170)
    including:     1.5 m at 7.48% U3O8
- MWNE-10-629:     9.5 m at 1.20% U3O8      100 m west of discovery (09-170)
    including:     2.0 m at  5.50% U3O8

Mineralization is not fully tested on any of the fences, as demonstrated in Figure 3, for example. There is significant potential to intersect high grade uranium mineralization during more tightly spaced follow-up infill drilling.

Summary of RRE Results

Extensive high grade mineralization was delineated at RRE this winter by the detailed drilling of 15 drill holes on two fences spanning 25 m of strike west from the discovery 170. Significant intersections are summarized below, and shown in the schematic section in Figure 4.

- MWNE-10-608:     5.34% U3O8 over 15.5 m, starting at 293.5 m depth
- MWNE-10-609:     3.65% U3O8 over 25.5 m, starting at 294.5 m depth

- MWNE-10-612:     11.75% U3O8 over 19.0 m, starting at 311.0 m depth
- MWNE-10-613:     1.25% U3O8 over 16.0 m, starting at 293.0 m depth
- MWNE-10-607:     81.5 m of 1.6% U3O8, including
                   13.5 m of 6.1% U3O8

Context

Figure 1 shows the 400 m strike length covering the Roughrider uranium deposit and the Roughrider East (RRE) discovery. Of the 77 holes drilled for 26,928 metres during the 2010 winter program, 30 holes were completed on RRE for a total of 11,951 m (Figure 2).

Preliminary scintillometer data for drill holes from Roughrider East were released on February 25, March 3, and April 21, 2010. Geochemical assays from drill holes MWNE-10-600C to MWNE-10-614 were reported on March 3, March 5 and April 27, 2010. This release covers assay data for drill holes MWNE-10-615 to MWNE-10-629.

Potential Upside

There are two important results from this winters drilling at RRE:

- Delineation of uranium for 100 m westward from the RRE discovery increases the possibility of outlining a 400 m east-west strike length to the overall Roughrider uranium system.

- Delineation of high grade uranium mineralization across Lines 0W to 25W at RRE, which enables the outline of a uranium zone of significant size.

The Company has initiated a detailed, hole by hole, section by section delineation of uranium mineralization based on all drilling done to date. There is significant upside potential to the overall resource at the Roughrider uranium deposit based on mineral zones at RRE, as shown on Figure 5.

Exploration and mineralization attributes at RRE are similar to, and in many cases more prospective than those at the original Roughrider deposit as currently outlined in the initial 43-101 compliant resource model completed by Scott Wilson Roscoe Postle Associates Inc. (SWRPA) in December of last year based on drilling completed prior to the summer of 2009 (filed on SEDAR and available on the Company's website at www.hathor.ca). Compelling attributes at RRE include:

Mineralization

- Near-continuous uranium mineralization over a vertical extent of up to 100 m

- Near-continuous uranium mineralization across a structural width of up to 60 m

- Visible chalcopyrite mineralization, with up to 7.5% Cu in a single half metre sample, and up to 2.27% Cu over 12.0 m in composite sections.

- Extensive clay alteration in the basement

Exploration (Figure 6)

- RRE correlates most closely with the projection of the "Midwest uranium trend" based on integrated regional- and property-scale geophysical models.

- RRE occurs at the northwestern edge of a pronounced resistivity low associated with the Midwest trend; the center of this anomaly is approximately 100 m south of hole 170.

- Both Roughrider and RRE are associated with depressions in the unconformity. The unconformity is typically 10-15 m deeper at RRE compared to RR.

Immediate Follow-up Drilling

Summer drilling is planned to start imminently at RRE. There are two main goals:

- One drill rig will test the open area to the east, and complete more detailed drilling (in-fill) to the west on Lines 20W to 100W. Uranium mineralization has been traced westward for 100 m from the discovery hole 170, but only in reconnaissance fashion for the western 80 metres. There is no drilling east of hole 170.

- One drill rig will test the resistitivty low, that is, the potential extension of the high grade mineralization at RRE to the southwest along the Midwest Trend. This target is robust over a strike length of approximately 700 metres.

Also, infill and expansion drilling will continue this summer, from the barge, at Roughrider itself.

Ownership

Terra Ventures Inc. owns a qualified 10 per cent interest in the Midwest Northeast property, carried until a decision is made to go to production based on the completion a feasibility study.
