Hathor Continues to Grow Roughrider as Far East Discovery is Expanded Upon Completion of 2011 Winter Drill Program
VANCOUVER, April 11 /PRNewswire/ – Terra Ventures Inc. (TSX-V: TAS) is pleased
to provide an update on the Midwest Northeast Uranium property in which
Terra owns a 10% production carried interest. In a press release dated
April 11, 2011, Hathor reported:
“Hathor Exploration Limited (TSX: HAT) is pleased to announce the
completion of the 2011 winter drill program at Roughrider in the
Athabasca Basin, Saskatchewan, and in particular, the confirmation of a
third mineral zone in the Roughrider system, named Far East and located east of the previously discovered East Zone. Highlights
and key attributes of the Far East Zone include:
-- Elevated radioactivity in 15 of 17 drill holes completed at Far East around discovery hole MWNE-11-667, which intersected 1.57% U308over 37.5 m (Feb. 24, 2011 News Release). -- Nearly continuous radioactivity over drill lengths up to 50 m -- Off-scale radioactive intervals in 13 of the 15 drill holes with anomalous radioactivity, and off-scale radioactive intervals totalling up to 8.9 m in a single hole -- Semi-massive and massive pitchblende mineralization in replacement, vein, fracture lining and breccias textures -- Locally pervasive alteration surrounding basement-hosted mineralization, and also at the unconformity above -- Drill intersections span 45 metres of strike, in an easterly direction, across mineral zones dipping moderately north-northeast; intersections of 30-50 metres are oblique to true thickness -- Mineralization is basement-hosted, up to 200 m below the unconformity, and not restricted to Wollaston Group lithologies
Figure 1 shows all drill holes completed during the winter program. Figure 2 is a more detailed plan map which provides detail of the infill holes
completed at East Zone, and delineation holes at Far East Zone. Figure 3 is a cross section along Line 110E, showing three drill hole
intersections, and the relationship between alteration and
mineralization, including the extensive alteration at the unconformity
above; Figure 4 is a zoom in of the same section view as in Figure 3, showing better the detail of radioactive zones. Figure 5 is a long section, with drill hole MWNE-11-683 for cross-reference with
the cross sections. Styles of uranium mineralization are shown in Photo 1, Photo 2, Photo 3 and Photo 4.
Overall, the Roughrider Far East zone remains open (untested) to the
east, and it will be the focus of an aggressive follow-up drill program
this summer. It represents a material development in the resource
potential of the overall Roughrider uranium system, as shown in Figure 6.
2011 Winter Program Summary
The 2011winter program utilized three drill rigs. A total of 19,244 metres were completed in 49 drill holes (Figure 3). A breakdown of holes is as follows:
- Roughrider Far East Zone (Line 80E to Line 17 drill holes 7,587 m 130E) - Roughrider East Zone Infill (Line 100W to 14 drill holes 5,200 m Line 70E) - "Gap" between Roughrider West and East 9 drill holes 2,768 m Zones: (From 110W to 180W) - Reconnaissance, Resistivity and Magnetic 9 drill holes 3,689 m targets
This News Release covers all drill holes completed at Roughrider this
winter. Infill drill holes at East Zone contained variable amounts of
mineralization. These assays, when available will be incorporated into
the resource model currently being developed and evaluated for the East
Zone. Drill holes in the “Gap” contained local radioactivity and trace
uranium mineralization, but did not return any material intersections.
In addition to a basement target, pervasive alteration at the
unconformity was intersected in several of the drill holes.
Reconnaissance drill holes on resistivity and magnetic targets
elsewhere on the property did not produce any material radioactive
intersections, but improved the geological and exploration models for
the Roughrider system and the Midwest uranium trend; follow-up drilling
this summer will be considered once all geochemical data are in-hand.
Radioactivity summaries of individual drill holes are provided at the
end of this release. Complete assays for complete drill holes will be
released when available.

Natural gamma emission radiation is measured in counts per second (cps)
using a SuperSCINT RS-120 hand-held gamma-ray scintillometer. While the
upper detection limit of the RS-120 scintillometer is greater than that
of the Exploranium GR-110, for continuity purposes, all values than are
>9999 cps are continued to be classified as “off-scale”. The reader is
cautioned that scintillometer readings are not directly or uniformly
related to uranium grades of the rock sample measured, and should be
used only as a preliminary indication of the presence of radioactive
materials. All intersections are down-hole, core-length intervals and
true thickness of mineralization is yet to be determined.
