West McArthur
|
|
|
Location:
This
project lies between 6 and 30 km west of the producing McArthur
River mine (436 million pounds U3O8
grading 25%U3O8 per tonne).
Geology:
Basement
rocks comprising Archean granitoids and Lower Proterozoic (Trans
Hudson) Wollaston and Mudjatik group metamorphic rocks.
These
metamorphic rocks are composed of supercrustals (psammites,
pelites and minor greenstones) and associated intrusions. These
are overlain by an estimated 600 to 850 metres of flat-lying
Athabasca sandstones and conglomerates.
Exploration
Prior
work by Kerr Addison, Cogema, and Cameco includes airborne
and ground geophysics, lithogeochemical surveys and lake
sediment surveys covering more than half of the property which
are documented in some 61 assessment reports. Several EM
conductors are present, some of which have been drilled on
adjoining ground. CanAlaska has used GIS in compiling these
existing datasets and has assimilated them to create a powerful
exploration tool.

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.
Previous exploration was hampered by the depths to the
basement, however, recent advances with Megatemtm.,
airborne geophysical survey technology has enabled penetration
to those depths. In winter 2005, the survey flown by CanAlaska
located previously unknown conductive zones, and sharply defined
the known conductors (see
April 19, 2005 release). These have been
earmarked for high priority follow up ground-based geophysics
and geological studies.
West
McArthur Project
This
extensive project, located 7 -- 27 km west of the
McArthur River Uranium Mine, has six priority drill
target areas. These are derived mainly from the
interpretation of the early 2005 Megatem II
electromagnetic survey, combined with geology
interpreted from aeromagnetic data, and nearby drill
holes. Detailed follow-up ground geophysics over the
past four weeks has concentrated on direct
measurement of alteration within the Athabasca
sandstone cover rock over two of these drill target
areas. |

 |
Preliminary
results from the first ground geophysical surveys of
rock resistivity have provided strong evidence of
alteration within the sandstone cover above basement
conductors, from the unconformity to at least 400
metres above the unconformity on the first of four
grids (see attached graphic). President Peter
Dasler notes: "This is a most significant
confirmation of a hydrothermal alteration system
directly related to the Megatem electromagnetic
discoveries. We are surprised at the quality
of the data defining the first zone surveyed (MC-1,
see attached graphic). In the next weeks, we
expect to receive airborne gravity data to further
profile the zones. We eagerly await the
opportunity to drill test the targets."
Strategic Partnership (see April 11, 2007 news release)
CanAlaska entered into an option agreement with Mitsubishi Development Pty Ltd.
("MDP"), an Australian-based mining company wholly-owned by Mitsubishi Corporation of Japan, to undertake uranium exploration on the West McArthur project. MDP may acquire a 50% ownership interest in the West McArthur Project by expending a minimum Cdn$11.0 million in cash and exploration payments to CanAlaska over a 3½ -year period. Upon MDP fulfilling its exploration commitments under the Option Agreement, the parties will enter into a 50/50 joint venture. To-date, MDP has expended over
Cdn.$8 mil. in exploration and will be supporting further drilling on the project in Winter 2009.
