KAM Highlights
Drilling completed in 2008 significantly expanded the size potential of the KAM prospect. Mineralization at KAM is near surface and open to the north, south and at depth.
Drill holes intersected high grade uranium mineralization including:
- 10 metres of 0.30% (6 lbs/ton) U3O8
including 4 metres of 0.56% (11.2 lbs/ton) U3O8
- 5 metres of 1.59% (31.8 lbs/ton) U3O8
including 1 metre of 1.16% (24.3 lbs/ton) U3O8
- 9 metres of 0.36% (7.2 lbs/ton) U3O8
including 4 metres of 0.7% (15.4 lbs/ton) U3O8 and
including 1 metre of 1.59% (31.8 lbs/ton) U3O8
- 8 metres of 0.12 (2.64 lbs/ton) U3O8
including 4 metres of 0.21(4.4 lbs/ton) U3O8
The KAM prospect is one of a number of uranium targets on Uranium North's South Baker Project in Nunavut. The KAM property was discovered in 1978 and explored by Urangeshellschaft Canada Limited until 1982. There work identified the KAM North and KAM South mineralized zones. Based on drill hole data, the strike length of the KAM south mineralized zone is a minimum of 250 m and appears to be open to the south and north. The north zone is marked by a 60 m by 50 m boulder field.
Work completed over the past two years by Uranium North included an airborne magnetic and radiometric survey, rock and soil sampling, geological mapping, and diamond drilling. This work has significantly expanded the size potential of the KAM prospect. This work is summarized below.
Summary of Exploration
Part of the 17,865 line kilometer airborne magnetic and radiometric survey completed by Terraquest Limited, at a line spacing of 100 metres, covers the KAM prospect. This is the first comprehensive survey flown in the area since 1976. Linear magnetic low features identified from the magnetic data, which may relate to structurally controlled alteration associated with uranium mineralization, are coincident with a uranium-bearing boulder train that extends for approximately two kilometres. Further, a radiometric anomaly identified along the magnetic low feature is coincident with uraniferous boulders collected in 2007 that have yielded U3O8 values ranging from less than 0.1 to 2.98%.
More than 224 rock samples were collected in 2007. More than 40% of the samples exceed 0.2% U3O8 including numerous boulders exceeding 1% U3O8.
Of special interest is one area measuring approximately 150 x 100 metres contains 9 boulders with U3O8 values exceeding 1%. Coincident enzyme leach soil geochemical anomalies (up to 2 orders of magnitude above background) support the possibility of a local 150 x 100 metre bedrock source of high-grade uranium mineralization.
Limited soil geochemistry completed by the Company to date over this area strongly suggests that the uraniferous system is open to the west with an unknown width.
The boulders are gneissic in composition and exhibit chlorite-hematite alteration and periodically strong silica filled brecciation textures. Uranium mineralization occurs as uranium oxides and hydroxides including pitchblende and is often associated with pyrite and chalcopyrite.
Based on the results of the 2007 exploration program a drill program was planned for 2008. A total of 1060 metres of drilling were completed in six holes. All holes were inclined 45 degrees. The drill results significantly expand the size potential of the KAM prospect. Mineralization at KAM is near surface and is open to the north, south, and at depth. Surface exploration indicates additional uraniferous zones may exist to the west.
Drill hole K-05-08 intersected two zones: a 10 metre zone grading 0.3% (6.0 lbs/ton) U3O8 including 4 metres of 0.56% (11.2 lbs/ton) U3O8, and a 5 metre zone of 0.42% (8.4 lbs/ton) U3O8 including 1 metre of 1.16% (23.2 lbs/ton) U3O8 (see table below).
Drill hole K-03-08 collared approximately 100 metres from K-05-08, also intersected two zones: a 7 metre zone grading 0.23% (4.6 lbs/ton) U3O8, and a 9 metre zone grading 0.36% (7.2 lbs/ton) U3O8. The latter includes a 4 metre zone of 0.7% (14 lbs/ton) U3O8 which contains a 1 metre interval of 1.59% (31.8 lbs/ton) U3O8 (see Table Below).

All intersections reported are down-hole, core-length intervals. The true thickness of mineralized zones is yet to be determined.
K-06-08 drilled 102.7 metres of volcanic rocks belonging to the Christopher Island Formation before penetrating basement rocks. A 1 metre zone of 0.10% (2 lbs/ton) U3O8 was intersected. It is likely that this hole overshot the main target horizon.
An additional drill hole was collared 2 kilometres to the west to test the possible westerly extent of the mineralized zone. The hole was lost before intersecting bedrock.
Exploration History
Exploration for uranium in the eastern Baker Lake region began in the 1960's with Aberford Resources, and continued over the succeeding years (primarily the later 1970's and early 80's) by Urangesellschaft Canada Ltd., AGIP/NorEx joint venture, and E&B Explorations Ltd. These companies focused on the faulted contacts/unconformity between the Proterozoic supracrustal rocks of the Baker Lake Basin with the underlying Archean gneissic granitoids. Numerous geochemical and geophysical surveys were performed including radiometric airborne surveys, mapping, prospecting, soil gridding, and to a moderate degree - drilling. Consequently, several prospective showings and anomalous boulder trains were discovered, including the KAM prospect.
Exploration work at the KAM prospect was conducted by Urangeshellschaft between 1978 and 1982. The KAM prospect is comprised of north and south mineralized zones located approximately 900 metres apart. KAM South is marked by a 1600 metre east-west trending radioactive boulder train with boulders assaying up to 4.04% U3O8 with average values of 0.69% U3O8. KAM North is marked by a 60 by 50 metre
boulder field, with assays returning values up to 5% U3O8 with average values of 2.0% U3O8
Ten BQ diamond drill holes were completed for a total of 1584 metres in 1982 by Urangesellschaft. Nine were drilled in the KAM South zone and one on the KAM North zone. Four of the drill holes at the south zone intersected uranium mineralization as shown in the table below. drill hole DDH-2 which intersected five uranium zones including 1 metre of 0.23% U3O8, 1 metre of 0.05% U308, 3 metres of 0.13% U308 and 2 metres of 0.17% U308 and drill hole DDH -3 which intersected 3 metres of 0.17% U3O8 including 1 metre of 0.44% U3O8.

In addition, drill hole DDH-1 intersected uranium mineralization in three horizons east of DDH-2. Only one sample was analyzed which showed a U3O8 content of 0.015% over 1 metre. DDH 2 and DDH 3 were both drilled within an area covered with radioactive boulders, while DDH-5 was outside the boulder field by an estimated 100 metres. The presence of uranium rich boulders suggest that the mineralization occurs at the surface beneath about 5 to 10 metres of overburden.
The single hole drilled into the north zone also encountered uranium mineralization in the same geological rock type as the south zone. Based on drill hole data, the strike length of the mineralized zone is a minimum of 250 metres and appears to be open to the south and north indicating that uranium mineralization could extend over 900 metres to KAM North. The drill holes confirm high-grade uranium over several intervals from near surface to a depth of 140-metres downhole.
A considerable amount of additional drilling was recommended by Urangesellschaft on the KAM North and KAM South occurrences in 1982. There are no known reports of this drilling being carried out.
