Purepoint Uranium Group Inc.: Radon Lake Exploration Update

Marketwired
Purepoint Uranium Group Inc. (TSX VENTURE: PTU) is pleased to
provide the following update on its recent first pass drill program
at the Radon Lake Zone of their Red Willow Property in
Saskatchewan's Athabasca Basin.
Purepoint tested the Radon Lake conductor with 13 drill holes
for a total of 2,726 metres over a distance of approximately two
kilometers. As predicted, the region demonstrated favourable
indications of potential uranium deposition. In addition to strong
clay and sandstone alteration, anomalous radioactivity was
intersected above the unconformity (RL08-09), at the unconformity
(RL08-05) and within the basement rocks (RL08-02 and 06).
"The source of the high radon-in-water anomaly at Radon Lake has
been a mystery since its discovery by Gulf Minerals in 1971" said
Scott Frostad, VP Exploration of Purepoint. "Though our drill
program in this area produced several uranium mineralized
intercepts, we now believe that the primary source of radon most
likely lies to the north of the Lake itself, and remains on our Red
Willow property to be discovered."
Highlights
- Radon is a short lived, radioactive gaseous element formed by
the decay of radium which itself is a decay product of uranium. The
lake overlying the conductor demonstrates high radon gas levels fed
from a local source.
- An alteration zone above the unconformity (sandstone) at Radon
Lake (hole RL08-09) returned 656 ppm U over 0.3 metres (over 200
times background levels) while other holes intersected narrow
radioactive fractures (greater than 100 ppm U) up to 40 metres
below the unconformity.
- The Radon conductive trend hosts Areva's Burnt Island showing
(1.8% U3O8 over 0.5m) located only 1,500 metres west of the Red
Willow boundary.
- Recent Purepoint geophysical surveys at Radon Lake extended
the length of the conductor to over three kilometers.
Purepoint's 100% owned Red Willow property adjoins AREVA 's
claim group that contains the JEB, Sue, McClean and Caribou
deposits to the west, as well as UEX's Hidden Bay project that
surrounds the Rabbit Lake, Collins Bay and Eagle Point deposits to
the south.
The Radon Lake Zone is located approximately six kilometers
south of the Red Willow Osprey Zone. In April 2008, Purepoint
reported diamond drill hole RW-19 from the Osprey Zone had
intersected a structure averaging 0.58% U3O8 over 1.0 metre at a
shallow depth of less than 100 metres and included an interval
assaying 3.03% U3O8 over 0.1 metres. RW-19 is located approximately
80 metres north from the Osprey Zone discovery hole RW-07, which
reported 0.20% eU3O8 over 5.8 metres in December 2007.
Radon Lake Zone
Interest in the area began in 1971 with the discovery of high
concentrations of radon found in the surface water. The area was
also found to have anomalous radioactivity in the overburden. In
1981 three holes drilled by Gulf Minerals north-west of Radon Lake
all intersected graphite with the best result being 76 ppm U over
1.0 metre.
Purepoint tested the Radon Lake conductor with thirteen drill
holes over a distance of approximately 2 kilometers. Anomalous
radioactivity was intersected above the unconformity (RL08-09), at
the unconformity (RL08-05) and within the basement rocks (RL08-02
and 06). These four holes are spread out over a distance of 1.6
kilometres. The electromagnetic conductor was explained by
graphitic pelitic basement rocks in 6 of the 13 drill holes.
RL08-02 encountered a radioactive structure within pelitic
basement rocks that returned 180 ppm U over 1.0 m from 118.0 to
119.0 m. The structure was associated with fault gouge, quartz
veining, limonite and chlorite alteration. RL08-05 intersected
radioactivity at the unconformity that was strongly clay altered
and assayed 189 ppm U over 0.3 m between 117.7 and 118.0 m. RL08-06
intersected a radioactive fracture approximately 39 metres below
the unconformity within a pelitic unit which returned 102 ppm U
over 0.3 m from 150.0 and 150.3 m.
RL08-09 provided the best uranium intercept of the drill program
from limonite altered sandstone returning 656 ppm U over 0.3 metres
between 106.2 m and 106.5 m. The altered sandstone returned a
weighted average of 175 ppm U over 1.1 metres between 106.9 and
107.2 m.
About Purepoint
Purepoint Uranium Group Inc. is focused on the precision
exploration in the Canadian Athabasca Basin of more than 42 defined
target areas on its eleven 100% owned projects, and its two Basin
projects joint ventured with Cameco Corporation and AREVA Resources
Canada Inc. Established in the Basin well before the resurgence in
uranium, Purepoint is actively advancing this large portfolio of
multiple drill targets in the world's richest uranium region.
