New Mineralization Discovered in Area 3 at Roughrider, With Assays Up to 26.5 m of 3.55% U3O8, Including 6.0 m of 14.46% U3O8

Hathor Exploration Limited (TSX VENTURE: HAT) announces the second set of assays from the 2010 winter drill program on the Roughrider uranium deposit at its Midwest Northeast property in the Athabasca Basin in northern Saskatchewan. New and high grade uranium mineralization was discovered in the central part of the deposit. Highlights of assays from the new intersections include:

1. Intersections of high grade mineralization adjacent to and outside of the Initial Resource Model.

For example: Drill hole MWNE-10-192: 26.5 m of 3.55% U3O8, including 6.0 m of 14.46% U3O8

(ii) See cross section in Figure 4.

2. Intersections of high grade uranium mineralization BOTH within and below the lower grade outer shell of the Initial Resource Model.

For example: Drill hole MWNE-10-179: 22.5 m of 2.80% U3O8, including 5.0 m of 6.23% U3O8 and 3 m of 7.68% U3O8.

(ii) See cross section in Figure 3.

3. Intersections of new uranium mineralization in two separate areas shown as unmineralized within the Initial Resource Model.

For example: Drill hole MWNE-10-187a intersected 9.5 m of 2.64 % U3O8.

(ii) See cross section in Figure 2.

These new assays confirm the potential to increase the resource at Roughrider, as first indicated by the preliminary scintillometer data released as drilling progressed (March 29, 2010 NR).

Assay results from the 27,000 metre 2010 winter drill program for the Roughrider uranium deposit are being 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 3, for which scintillometer data were released on March 29, 2010. 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 the 30 drill holes completed at Roughrider East this winter for 11,951 metres, while Figure 2 shows the location of the 47 drill completed for 14,978m on the Roughrider deposit itself.

A total of 15 drill holes were completed in Area 3 for approximately 4,600 metres. The holes span grid lines 40E to 70E in the central part of the deposit. As shown on Figure 2, Area 3 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.

Assays have been received for fourteen of the fifteen holes completed in Area 3; assays for drill hole 10-211 have not been received from the laboratory. All fourteen holes intersected uranium mineralization (greater than 0.05% U3O8). Three drill holes have a combined Grade-Thickness factor (GT) of less than one, two drill holes have a GT of between 5 and 10, six drill holes have a GT of between 10 and 50, and three drill dills have a GT of greater than 50. A summary of drill hole results is provided below and a full list of composite assay results are in Table 1 at the end of this News Release.

Summary of Area 3 Drill Holes

Line 40E

Drill holes 10-192 and 10-191 were designed to test the mineralization inferred to be down-dip from drill hole 09-47A. Both drill holes successfully intersected mineralization that was higher grade and wider than that modelled in the Initial Resource Model. Drill hole 10-191 intersected several zones of mineralization that include 12.5 m of 2.58% U3O8 and 8.5 m of 0.63% U3O8. Drill hole 10-192 intersected a wide zone of mineralization that returned 26.5 m of 3.55% U3O8 , which includes a higher grade zone of 14.46% U3O8 over 6.0 m. Drill hole 10-195 is an infill drill hole between drill holes 09-47A and 09-44 and intersected 5.0 m of 1.21% U3O8.

Line 50E

Drill holes 10-179, 10-182, and 10-185A were planned as infill holes within the lower grade outer shell of mineralization and successfully intersected wide zones of higher grade uranium mineralization, including 22.5 m of 2.8% U3O8, 22.5 m of 2.55% U3O8, and 12.0 m of 1.0% U3O8, respectively. Further drilling is still required to the west of 09-161C.

Line 60E

Drill holes 10-196 and 10-198 successfully intersected mineralization within an area shown as not having any mineralization in the Initial Resource Model because of a lack of drill information. Drill hole 10-196 intersected 16.0 m of 2.4% U3O8 and drill hole 10-198 intersected 9.5 m of 2.62% U3O8. Drill hole 10-177 was planned to test the thickness of the mineralization acutely intersected in drill hole 08-30. It intersected 5.5 m of 3.04% U3O8. Drill holes 10-173 and 10-174 were designed to test for mineralization at the down-dip northern extent of the deposit. Hole 10-174 intersected 3.0 m of 2.27% U3O8, but did not intersect the intended target. More drilling is required to fully delineate the northern limit of the deposit.

Line 70E

Drill holes 10-187A and 10-189 were designed to test the inferred mineralization down dip from holes 09-88 and 09-110C. Drill hole 10-187A intersected 9.5 m of 2.64% U3O8. Drill hole 10-189 intersected 5.5 m of 0.15% U3O8. Geochemical data has yet to be received from drill hole 10-211; it successfully intersected uranium mineralization and infilled the second "hole" internal to the Initial Resource Model (see Figure 2)

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.

All intersections are down-hole, core-length intervals and true thickness of mineralization is yet to be determined.

Ownership

Terra Ventures Inc. owns a 10-per-cent interest, carried until a decision is made to go to production, in the Midwest NorthEast property.
