SASKATOON, June 24 /CNW/ - Star Uranium Corp. (SUV-TSX Venture) announces
drill results for Stony Rapids and Collins Bay winter exploration program.
Core logging and sampling of the core from the winter drilling programs
on the company's Stony Rapids and Collins Bay properties is now complete, and
analytical results have been received.
All three of the holes on the Stony Rapids property intersected Athabasca
sandstone then passed through the unconformity and into hematized basement
rocks. The first hole, SS08-1, intersected about 172 metres of sandstone, but
was lost due to technical drilling problems only about 12 metres into the
basement. Uranium values increase towards the unconformity from a low of
0.31 ppm to a high of 6.32 ppm (partial digestion of sample) a few meters
above the unconformity. The corresponding uranium values for a total digestion
of the sample are 1.18 ppm and 18.7 ppm. The number of analyses in the
basement is too small to reveal any pattern. Several other elements increase
towards the unconformity as well, and combine to reveal a weak alteration of
the sandstone. This indicates that the process that can form uranium deposits
has been active here, but not to the extent of forming a potentially economic
deposit. This level of alteration and mineralization can be found at many
places in the basin.
Hole SS08-2 was drilled 2 km northeast of hole SS08-1. It intersected
about 95 m of sandstone, and then passed into basement rocks identified as the
mafic granulite shown in the Saskatchewan Geological Atlas. The pattern of
element concentrations in this hole is similar to that in SS08-1, i.e. a low
of 1.19 ppm uranium (partial extraction) or 3.32 ppm (total extraction) about
40 m above the unconformity and a high of 17.5 (partial) or 28.6 ppm (total)
about 5 m above the unconformity, with a generally similar pattern in many
other elements. This hole was drilled well into the basement, and the
analytical results show uranium and other elements decreasing in concentration
away from the unconformity, from a high of 11.8 ppm uranium (partial
digestion), or 17 ppm (total) to a low of 2 ppm (partial) or 3 ppm (total)
about 5 metres below the unconformity. Of note in this hole are values of
chromium from 1320 ppm to 2460 ppm in the upper 4 metres of the basement
rocks, and values of chromium of 1850 ppm and 1740 ppm in two samples at about
126 and 139 metres depth respectively. The basement rocks also contain values
of nickel from 277 to 609 ppm (partial) or 472-868 ppm (total).
All of the holes were drilled to test weak conductors and the cause of
the conductor here would appear to be moderate to weak clay alteration a few
metres below the unconformity.
Hole SS08-3 was drilled 1.2 km north of hole SS08-2, close to the edge of
the Athabasca basin. It passed through about 34 metres of sandstone before
intersecting the unconformity. In this hole the highest uranium analyses
(25.3 ppm partial, 27 ppm total) were in the upper half-metre of the basement
(mafic granulite), and decreased rapidly below that. Here, too, the patterns
of concentrations of other elements indicate that the mineralizing process was
active, but not strongly enough to form a uranium deposit. As in hole SS08-2,
chromium values are noteworthy, from 1370 ppm to 2110 ppm in the upper three
metres of the basement, and 3100 ppm over 0.6 m in a zone of disseminated
sulphides at a depth of about 211 metres below the collar. Nickel values are
254-293 ppm (partial) and 435-480 ppm (total) in the upper three metres of the
basement, and the sample at about 211 m depth contains 1170 ppm nickel
(partial) or 1500 ppm (total). This sample also contains 457 ppm copper
(partial) or 519 ppm (total), which is much greater than any copper values
found in the other samples.
In the Collins Bay project nine holes were attempted. Four holes were
completed in a fence in the northeastern corner of the property, and a fifth
was lost in overburden. The holes were 50 metres apart along a line trending
east-southeasterly. Two holes were drilled about 2 km west of the fence, and
two more were drilled about 2.5 km southwest of the fence.
As expected, none of the holes intersected any sandstone. The geologic
model here was a basement-hosted uranium deposit similar to Cameco's (CCO-TSX)
Eagle Point orebody located 2 km NW of Star Uranium's Collins Bay property.
The immediate targets were weak conductors outlined in work previously carried
out by the company.
The rocks intersected in all holes were of essentially the same two
types, i.e. a dominant coarse-grained to very coarse-grained pegmatoid rock
consisting mainly of quartz and feldspar, and a mafic gneiss. There were many
sections showing chloritic clay alteration, hematization, and fracturing, but
these were not of the intensity to be expected near a uranium deposit.
The sampling protocol for all of these holes was to sample sections with
some or all of alteration, fracturing, and higher-than-background counts of
radioactivity. The radioactivity of the core was measured with two hand-held
scintillometers, and most of the holes were also checked for radioactivity by
lowering a radiation detector down them. By this latter method, even if
radioactive material were not recovered in the core, it might be detected in
the wall of the hole.
The uranium analyses in all of the holes varied between a value of less
than the detection limit of 2 ppm, and 84.3 ppm (partial extraction) or
0.2 ppm and 86 ppm (total extraction). There is no pattern to the values, and
thus no mineralized "zone" is defined.
