Target selection completed for West McArthur
Multiple conductors and targets in 1.6 km (one mile) long zone
Large geochemical halos reach surface
Vancouver, Canada, January 18, 2019 -- CanAlaska Uranium Ltd.
DH7N)) ("CanAlaska" or the "Company") reports that
plans have been made for drill testing of the northern portion
of Grid 5, where Cameco identified multiple intercepts of
uranium mineralization in the most recent drill programs. See
previous news December 11, 2018. Under the Joint Venture with
Cameco, CanAlaska will act as Operator and plans to drill 7000
metres in 10 drill holes this summer to endeavor to intersect
lenses of higher-grade uranium mineralization.
West McArthur uranium discovery
In August 2017, Cameco intersected the first high grade uranium
mineralized intervals on the northern portion of the five-kilometre
long Grid 5 target area at the West McArthur uranium project.
The project extends over 36,000 hectares and the eastern
boundary is 6 kilometres (4 miles) northwest of Cameco's
majority-owned McArthur River uranium mine and associated
To date three holes have intersected mineralization, up to a
maximum of 1.51% U3O8 over 5.5 metres. The main anomalous zone
is situated at a flexure in the three recognizable conductors,
(the "C10" graphitic conductor package). Four kilometres to the
east, the C10 conductor hosts the Cameco/Orano Fox Lake high
grade uranium deposit.
Three graphite-bearing rock units ("conductors") define a 6.6 km
long conductive trend west from the Fox Lake uranium deposit
onto the West McArthur project. The first 1.6 kilometres (one
mile) of this trend onto the project hosts a significant
flexure, and the conductors rotate to the south. The large ZTEM
geophysical anomaly shows that this trend continues for a
further five kilometres to the south, and is shown as insert in
Figure 1. High grade mineralization was intersected at target B,
where the trend bends southward, 1,600 metres west of the
The eight drill holes carried out by Cameco, under their
previous option to earn 30% of the project, intersected a series
of geochemical halos around and above uranium mineralization.
The halos are very distinctive and characteristic of known
uranium deposits. The size of the halos, with boron and uranium
values to near surface, and high uranium and base metal values
at the unconformity, suggest the possible presence of
significant uranium mineralization. These targets are shown in
yellow on Figure 1.
The long section, shown in Figure 2, transects
the three conductors and shows the extent of anomalous uranium
intersected in the sandstone, extending 1600 metres in length
and as much as 700 metres in height above the unconformity
(Figures1&2), with uranium mineralized zones at, and above, the
The most obvious target for the next drilling will be close to
the intersections in drill holes WMA042 and WMA042-2 where a
five metre uranium mineralized horizon was intersected at the
unconformity. The nearest drill hole (WMA044) is 127 metres to
the SSE, and this has not explained the basement offset between
the target and drill hole WMA035, which is 300 metres to the SE.
This is shown as Target B in Figure 1.
The identified priority targets shown in Figure 1 are as
Target A has extensive uranium and boron in sandstone.
Drill holes WMA045 and WMA048, respectively, overshot and
undershot the C10 & C10N conductors.
Target B with high grade intersections requires close-in
follow up; WMA042 and 42-2 overshot the C10 conductor missing
the main target but matching basement alteration of WMA044.
Target C: The first program drill holes undershot C10S
target intersection with a uranium-arsenic anomalous fault zone
in sandstone of WMA044.
Target D: The drill holes undershot conductor C10S and
overshot C10. There is an extensive fault zone in the sandstone
of WMA046 which projects to the location of conductor C10 at the
Target E: Reconnaissance drill hole WMA050 overshot the
C10N conductor target. This is shown by the anomalous uranium
and arsenic perched in the fractured sandstone. This zone
projects eastwards to the location of conductor C10N at the
CanAlaska's President, Peter Dasler, comments: "We have a series
of exciting targets in a complex geological setting at the
flexure of the three conductors. The recent reconnaissance
drilling has given us mineralized targets for detailed
delineation. We have been able to attract senior staff who were
associated with the project during the option period and we all
look forward to operating the project, a good summer drill
season, and new successes."
