VANCOUVER, Jan. 5, 2017 /CNW/ - IsoEnergy Ltd.
("IsoEnergy" or the "Company") (TSXV:ISO) is pleased to report on the first stage of a two-stage drilling
program at each of its Thorburn Lake and Radio uranium projects in the eastern Athabasca Basin of
Saskatchewan. Results of Phase 1 drilling at Thorburn Lake include the intersection of
uranium mineralization in drill hole RD16-19, and elevated radioactivity at the unconformity in several other drill holes.
The highlight of Phase 1 drilling at Radio was the discovery of a large zone of basement clay alteration with a tenor and scale
that is typically found close to significant uranium mineralization, including the nearby Roughrider uranium
deposit.
IsoEnergy is undertaking a two-stage drilling program, where land accessible targets were drilled during the period September to
November 2016, whilst drilling of targets accessible upon ice formation will be undertaken in Q1
2017. Thorburn Lake, located 7 kilometres east of the Cigar Lake uranium mine, is 100% owned. IsoEnergy has an
exclusive right to earn a 70% interest in the Radio property, which is located 2 kilometres east of the Roughrider uranium
deposit.
Thorburn Lake – Elevated Radioactivity at the Unconformity
Six drill holes (2,587 metres) were completed at Thorburn Lake to follow up on two previous drilling campaigns in 2008 and 2011
that identified an area of anomalous radioactivity and geochemistry at the sub-Athabasca
unconformity. Previous results include 0.43% U3O8 over 0.6 metres in drill hole TBN11-05A. Figure
1 shows the drill hole locations at Thorburn Lake. Depth to the unconformity at Thorburn Lake ranges from 290 to 350
metres.
Elevated radioactivity at the sub-Athabasca unconformity was observed in five of the six
recently completed drill holes. The highlight was TBN16-19 where radioactivity up to 1,900 counts per second (30-40 times
background) was measured with a hand-held SRAT SPP2 scintillometer in an interval straddling the unconformity. Geochemical
results from the radioactive interval in TBN16-19 returned 0.10% U3O8 over 0.5 metres. Other
geochemical highlights include 524 ppm U over 0.5 metres (TBN16-17), 71 ppm U over 0.5 metres (TBN16-20), 55.4 ppm U over 0.5
metres (TBN16-15) and 47 ppm U over 0.5 metres (TBN16-16), all of which occur immediately adjacent to the unconformity. Other
encouraging features include strongly graphitic fault zones in drill holes TBN16-16, -17, -19 and -20, with zones of moderate to
intense sandstone alteration in drill holes TBN16-17 and -20. This zone of mineralization, alteration, structure, and
elevated radioactivity is open along strike in both directions and is strengthening to the northeast beneath Thorburn Lake.
Systematic sampling through the sandstone column for SWIR reflectance analysis indicates that the sandstone clay alteration zones
in TBN16-17 and -20 are dominated by illite and sudoite, similar to sandstone alteration zones around many unconformity related
uranium deposits in the Athabasca basin.
IsoEnergy is planning a 10 hole (4,300 metre) winter drilling program to follow up on the 2016 results. Drilling will be
carried out in conjunction with a program at the Radio property during the January to March 2017
winter drilling season. The primary target will be the northeast strike extension of the mineralization, alteration and
structural zone described above. Secondary targets include several resistivity low anomalies observed in an 85 line-kilometer
DC-resistivity geophysical survey completed in October 2016.
Radio Property - Basement Clay Alteration Zone
A total of 13 drill holes (4,946 m) were completed on the Radio property. Three main target areas were evaluated as shown
in Figure 2 below: (1) the central Roughrider Corridor of metasediments, (2) magnetic low anomalies along the Northern Corridor of
the property, and (3) weak but extensive clay alteration in 2013 drill hole RD13-08 along the Southern Corridor of Radio.
This last target area is the location of the basement clay alteration discovery. Depth to the sub-Athabasca unconformity at Radio ranges from 170 to 190 metres.
Five drill holes were completed in the vicinity of drill hole RD13-08 during the campaign. The initial target was the
up-dip projection of weak but persistent clay alteration in RD13-08 toward the sub-Athabasca
unconformity on cross section 400E (Figure 3). Drill hole RD16-11 was the first in the current program to target the area and
intersected 105 metres of moderate to strong structurally controlled grey and white clay alteration in the basement 280 metres
up-dip of RD13-08, and 200 metres down-dip of the unconformity. The zone is associated with several parallel (stacked)
graphitic fault zones that are conformable with the geology and foliation.
Drill hole RD16-17 was subsequently collared 75 metres up-dip of RD16-11 (also on cross section 400E) and intersected 130 metres
of weak to strong clay alteration in the lower sandstone and upper basement, demonstrating that the zone extends for a minimum of
75 metres along the dip direction. A fourth drill hole, RD16-19 was completed 75 metres up-dip of RD16-17. RD16-19
intersected only 25 metres of weak alteration in the sandstone and basement, suggesting that it over-shot the strong portion of the
alteration zone.
Drill hole RD16-21A evaluated the along-strike projection of the zone 200 metres to the northeast on cross section 600E, and it
intersected the strongest alteration to date, consisting of 120 metres of moderate to strong clay alteration in the basement,
beginning immediately below the sub-Athabasca unconformity. As with section 400E, the zone
is associated with parallel (stacked) graphitic fault zones that are conformable with the geology and foliation.
Samples of the graphitic fault zones associated with the basement alteration zone are elevated in common uranium pathfinder
elements such as molybdenum (up to 184 ppm), nickel (up to 274 ppm), cobalt (up to 45 ppm) and vanadium (up to 270 ppm).
Systematic sampling through the alteration zones for shortwave infrared (SWIR) reflectance analysis indicates that the clay
alteration zone is illitic, similar to the clay alteration zone that surrounds the nearby Roughrider deposit.
IsoEnergy is planning a 10 hole (4,100 metre) winter drilling program to follow up on the 2016 results. Drilling will be
carried out in conjunction with a program at the Thorburn Lake property during the January to March
2017 winter drilling season. The primary target will be uranium mineralization associated with the large zone of
basement clay alteration described above.
Steve Blower, Vice-President Exploration, commented: "Exploration success in the Athabasca basin usually begins with the intersection of significant alteration zones, which have a much larger
footprint than the bodies of uranium mineralization they encompass. The volume and intensity of clay alteration in the
southern target area at Radio is impressive and is similar to alteration haloes around the recently discovered Roughrider, Arrow
and Gryphon basement uranium deposits. I'm also encouraged by the size of the area of elevated radioactivity at Thorburn
Lake, especially considering that alteration and structure are improving toward the northeast. Both sites warrant additional
aggressive drilling campaigns during the January to March 2017 winter drilling season."
