Location
The Cree East project is a high-priority property located
in the south-eastern portion of the Athabasca Basin, 35
km west of the formerly producing Key Lake mine and 5 to
22 km north of the south rim of the Athabasca Basin. The
project is comprised of 16 contiguous mineral claims
totaling 55,935 ha.
Geology
The project area covers Athabasca group conglomerates and
sandstones. Sandstone unconformably overlies basement at
depths in the order of 200 to 300 metres in the south.
Structural breaks which trend across the across the
property further drop the basement to estimated depths
of 800 to 900 metres across the northern edge of the
property The basement is composed of the Lower
Proterozoic, (Trans Hudson) Mudjatik domain, granitoids
and associated minor supercrustals (psammites, pelites
and metavolcanics) A significant portion of the property
is considered to be underlain by rocks of the highly
prospective Wollaston Domain.
Past Exploration
Due to the project's proximity to the Key Lake mine, the
area has been explored since the early 1970's by SMDC
and Uranerz among others. Most of this exploration was
on the southern rim of the project area, as previous
airborne geophysical surveys had limited depth
penetration, and the depth to the unconformity increases
to the north. Regional geochemical studies and
geophysics have located numerous conductors around the
southern and eastern edge of the property. Some of these
conductors have been drilled, but the results have been
inconclusive.
Recent Exploration
CanAlaska carried out VTEM airborne surveys across
the property area in 2005 and determined priority
targets. In 2006, detailed collection of over 2,000
surface rock samples and over 400 lake sediment samples
by CanAlaska's field crews defined three large areas of
dravite and clay alteration on surface, and localized
boulder samples containing anomalous uranium. Before
April 30, 2007, initial ground geophysical data from the
first lines of IP-Resistivity surveys, provided the
Company with evidence of strong alteration in the
sandstone horizons overlying these basement conductors.
Additional IP-Resistivity and Audio Magneto Telluric
geophysical surveys were used to further define these
targets this year. Drill programs started on the project
in late February 2008 and large zones of alteration were
intercepted. Extreme clay alteration and unconsolidated
sands prohibited the Company from completing the
majority of the drill holes.
During the summer of 2008, CanAlaska Uranium Ltd (CanAlaska) undertook a
multi-faceted $1.6M exploration programme at its consisting of IP/Resistivity
surveying on land and high-resolution single channel seismic data
collection on Cree and McIntyre Lakes, lake sediment sampling on Cree
Lake, and a 5- hole diamond drilling programme. |

All of the drill holes
reached their target depth in basement. The 2008 summer-drilling
produced very positive results:• Strong fracturation and alteration
in most drill-holes.
• Faulting between many of the drill-holes
• Geochemical enrichment in uranium and other elements both in the
basement and in the sandstone.
• Boron is distinctly anomalous in the top sandstone of all drill-holes,
comparable to the results of the regional sandstone boulder sampling in
this area.
The winter 2009 Cree East exploration programme was successful in
drilling 15 holes for a total length of 6,747 metres, with only one
drill-hole abandoned in bad ground near surface. All of the holes but
one reached their targeted depth, and showed multiple zones of uranium
and basemetal enrichment, as well as basement offsets and hydrothermal
alteration.
In summer 2009 detailed geophysical surveys, and infill VTEM surveys
were used to prioritize target areas for 2010 drilling.
Potential The potential of this project is for
unconformity style Uranium mineralization of both the Simple (Low REE,
basement hosted) and the Complex (High REE, Sandstone hosted) types of
Uranium. The area has numerous conductors and faults which act as both
the conduit and the trap for potential Uranium mineralization. A number
of structures and conductive targets have been identified from the
Company's exploration efforts.
Strategic Partnership
The Cree East Project is funded
by a Korean consortium, comprising Hanwha Corporation, Korea Electric
Power Corporation, Korea Resources Corporation and SK Energy Co. Ltd. In
December, 2007, CanAlaska entered in a joint venture whereby the Korean
consortium may earn a 50% ownership interest in the Cree East Project by
investing Cdn$19.0 mil. towards exploration of the project.
