New Zones Discovered at Roughrider; Return Assays as High as 22.50 m of 11.31% U3O8

Hathor Exploration Limited (TSX VENTURE: HAT) announces the first set of complete assays from the 2010 winter drill program on the Roughrider uranium deposit at its Midwest Northeast property in the Athabasca Basin in northern Saskatchewan. A new zone of uranium mineralization was intersected in the western part of the deposit. Highlights of assays from the new discovery include:

1. Discovery of high grade uranium mineralization within, and extending beyond, the lower grade shell of the Initial Resource Model. For example: Hole MWNE-10-197a intersected 17.0 m of 15.20% U3O8.
2. Discovery of high grade uranium mineralization adjacent to and outside of the Initial Resource Model. For example: Hole MWNE-10-200 intersected 22.50 m of 11.31% U3O8.
3. Confirmation of high grade uranium mineralization inferred to be down- dip of the high grade shell within the Initial Resource Model. For example: Hole MWNE-10-188B intersected 7.5 m of 28.98% U3O8.

These new assays underscore the potential to increase the Initial Resource Model for the Roughrider uranium deposit, via both infill drilling and extension drilling on zones defined in the initial model, and by the discovery of entirely new zones. These new assays confirm the potential to grow the resource which was first indicated by the preliminary scintillometer data (April 13, 2010 NR), as clearly shown on the cross sections in Figure 3 and Figure 4 - (See Figure 2 for Location) available on the Company's website at www.hathor.ca.

Assay results from the 27,000 metre 2010 winter drill program for the Roughrider uranium deposit will be released in the same four blocks, or areas, that were used to organize and release the original scintillometer data (see news releases dated March 29, April 13, and April 15, 2010). This news release covers Area 1, the first area for which all assay results have been received. The remaining assay results will be reported in subsequent releases, including those for the Roughrider East discovery.

Figure 1 on the Company's website shows the 400 m strike length potential of the Roughrider uranium deposit and Roughrider East discovery. Figure 1 also shows the location of 30 drill holes completed at Roughrider East for 11,951 metres. Figure 2 is a plan map which shows the location of all 47 drill holes (14,978 m) completed on the Roughrider deposit itself.

A total of 13 drill holes were completed in Area 1, the western-most of the four areas covering the Roughrider uranium deposit as it is currently delineated. It spans span grid lines 45W to 5E. Of the 13 drill holes, 10 intersected uranium mineralization. Four have a Grade-Thickness factor (GT) of between 1 and 5, three have a GT of between 10 and 50, and three have a GT of greater than 200. A full list of composite assay results are shown in Table 1 at the end of this News Release.

Area 1 includes parts of both the high grade core shell of mineralization (greater than 5% uranium oxide) and the lower grade outer shell of mineralization (less than 5% uranium oxide), as defined by the Initial NI43-101 compliant resource model ("Initial Resource Model") completed by Scott Wilson Roscoe Postle Associates Inc. (SWRPA) in December, 2009. The report is posted on SEDAR and on the Company's website at www.hathor.ca, and includes all drilling prior to the summer of 2009.

The Roughrider uranium deposit remains open. More drilling is yet required to fully delineate the high grade uranium mineralization within the deposit as it is currently outlined. The deposit remains open down-dip to the northwest and to the north. Further, along-strike continuity to the east for some 200 metres towards the Roughrider East discovery is yet to be fully tested.

Summary of Assay Data for Area 1:

Line 0

Drill holes 10-197A and 10-200A were designed to test the down dip extension of the outer resource shell from Drill Hole 09-123. The mineralization intersected was much stronger and broader than that modelled in the Initial Resource Model. An upper zone, which correlates to the mineralization first intersected in 09-126 and subsequently in 10-200, returned 12.5 m at 0.49% U3O8. Two additional zones lower down, which occur both within and beyond the outer shell modelled in the Initial Resource Model returned 17.0 m of 15.20% U3O8 and 2.0 m of 0.5% U3O8. Hole 10-200A intersected 22.50 m of 11.31% U3O8 in a new zone of high grade, basement-hosted mineralization located approximately 10 m below the unconformity and not modelled in the Initial Resource Estimate, returned.

See Figure 3 Cross Section (April 13 NR) on the Company's website.

Line 10W.

Drill holes 10-188B and 10-190 were designed to test the mineralization inferred to be down-dip from drill hole 09-123 and along strike from 09-116. Drill hole 10-188B intersected numerous zones of mineralization containing semi-massive to massive to massive pitchblende and returned assays of 3.0 m of 0.15% U3O8, 2.0 m of 1.29% U3O8, 7.0 m of 2.27% U3O8, 4.0 of 1.82% U3O 8, and 7.5 m of 28.98% U3O8. Drill hole 10-190, which also intersected numerous zones of mineralization, returned assays including 11.5 m of 0.87% U3O8, 8.0 m of 0.75% U3O8, and 3.0 m of 0.17% U3O8 . The mineralization intersected in 10-188B and 10-190 confirm the presence of both high grade uranium mineralization which was inferred to be down-dip of the high high grade core shell within the Initial Resource Model Drill hole 10-193 returned 10.50 m of 3.67% U3O8. and successfully intersected the strike extension of the new shallow zone of mineralization discovered in Drill Hole 10-200 and 10-197A.

See Figure 4 Cross Section (April 13 NR) on the Company's website.

Line 20W.

Holes 10-178 and 10-186 were both designed to test the new shallow zone of mineralization located 6-10 m below the unconformity. They returned 6.5 m of 3.8% U3O8 and 2.5 m of 0.6% U3O8, respectively. Hole 10-175 was an infill drill hole between the mineralized hole 09-129 and the unmineralized hole 09-49. It intersected several thin zones of mineralization, including 1.5 m of 0.2% U3O8, 3 m of 0.15% U3O8, 6 m of 0.14% U3O8, and 3.0 m of 0.08% U3O8.

Line 30W.

Hole 10-176 was collared on 20W at the same location as 10-178, but the intersection is plotted on Line 30 W because of excessive drill swing. This drill hole intersected 2 main intervals of mineralization, an upper zone that returned 2.5 m of 0.17% U3O8 and a lower zone that returned 3.5 m of 1.20% U3O8.

Line 40W.

Holes 10-180, 10-181, 10-183, 10-184 were drilled to test for a possible southwestern extension of the Roughrider uranium deposit. Based on prior drilling information, drill holes 10-180 and 10-181 were considered to have a high probably of overshooting the expected strike extension. These two drill holes were completed to aid geological/geotechnical modelling of the architecture of the Archean Midwest Dome. Drill holes 10-180, 10-181 and 10-183 did not intersect any anomalous radioactivity (greater than 500 cps) and thus were not sampled. Drill hole 10-184 intersected several zones of mineralization over 17 m, including 3.0 m of 0.26% U3O8 and 0.5 m of 0.29% U3 O8. Further drilling is required to the southwest of this area to investigate the possibility of a new zone of mineralization, such as that recently discovered in drill hole 10-200A.

QAQC

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. Select samples will be analysed for precious metals including gold, platinum, palladium and rhenium. Dry bulk density determinations were also carried out on the drill core.

Field and laboratory of select samples show good reproducibility, consistent to those documented in the NI43-101 report containing the Initial Resource Model.
