Alamar Resources Ltd
Update on Uranium Projects
The directors of Alamar Resources Ltd (`Alamar' or the
`Company') are pleased to present an update on the company's
activities and strategy relating to its uranium projects.
Uranium Applications in WA
At the beginning of 2009 Alamar undertook to review the
opportunities for uranium exploration in Western Australia. The
company focussed on calcrete hosted deposits in the north-
eastern and central Yilgarn districts. The results of this review
have been the application for a total of six exploration licences
covering significant radiometric anomalies within paleo-drainage
systems.
The areas now under application include:
·
E36/723, a 42 square kilometre claim within the Yeelirrie
paleo-channel, which hosts BHP's Yeelirrie deposit, the
world's largest known calcrete hosted uranium deposit.
·
E29/734 (won in a ballot), a 108 square kilometre claim
hosting a 14km x 4km radiometric anomaly. The anomaly
has been only partially tested by drilling, with several
holes intersecting anomalous (+100ppm) uranium up to
1000ppm.
·
Four grass roots targets totalling approximately 400
square kilometres with little or no recorded previous
uranium exploration.
Upon granting of these exploration licences Alamar believes it
will have a valuable portfolio of underexplored and highly
prospective calcrete hosted uranium targets. The company is
currently reviewing its options for the advancement of these
targets, as well as potentially acquiring additional uranium
assets.

UPDATE ON URANIUM PROJECTS
Targeting for Calcrete Hosted Uranium Deposits in Western Australia
There are a number of well known calcrete hosted uranium deposits in Western Australia,
such as Yeelirrie, Lake Maitland and Lake Way. An initial review of the radiometric
responses of the known deposits in open file radiometric data found that virtually all known
deposits have a recognisable signature in either the uranium (U) count or in a ratio of the
uranium: thorium (U/Th) counts. Open file radiometric data was subsequently obtained from
the Department of Mines and Petroleum and assessed for similar signatures to the known
deposits in the context of a simplified model for calcrete hosted uranium deposit formation.
Components of the deposit model considered when assessing radiometric anomalies
included:
·
Source rocks uranium rich (compared to normal background levels) granites
·
Pathway erosion and weathering of the granites, dissolution of uranium into
groundwater and transport along paleo-drainages.
·
Focus concentration of uranium rich groundwater (channels, lakes)
·
Trap precipitation of uranium as carnotite caused by change in ground water
chemistry (fluid mixing, Ph change etc). The precipitation of carnotite requires
vanadium the nearby presence of highly magnetic rocks were used as a proxy for
the presence of vanadium.
Figures 1 and 2 show the locations of Alamar's tenement applications in relation to
topography and radiometric response. A summary of the targets identified within these
exploration licences are as follows:
Laverton Region, E38/2260, 2261, 2262 (Figure 3)
All of the Laverton tenements cover grass roots targets that have to Alamar's knowledge not
previously been systematically explored for uranium.
E38/2260 occurs at the northern extent of the Lake Throssell drainage system,
approximately 250km north-east of Laverton. There is good access to the project along the
Laverton-Warburton road. There have been recorded occurrences of carnotite within this
drainage system and E38/2260 covers the highest radiometric response (U, U/Th ratio)
within the north-eastern arm of this drainage system. The anomaly is approximately 10km x
1km in size, but may be truncated to the west by aeolian sand cover.
E38/2261 occurs at the upper reaches of an interpreted paleo-channel draining granites with
a high radiometric response. The licence is approximately 50km north east of Laverton with
good road access. The tenement covers a strong radiometric U/Th ratio anomaly and
moderate U anomaly over an area of approximately 7km x 3km.
E38/2262 occurs on the western margin of the Lake Wells drainage system, approximately
200km north of Laverton. The tenement covers a strong radiometric U/Th ratio anomaly and
moderate to strong U anomaly over a strike length of approximately 18km.

Central Yilgarn Region E36/723, E29/734, E59/1628 (Figure 4, 5, 6)
E36/723 covers an area within the Yeelirrie paleo-channel, just 4km from the Yeelirrie South
(Little Well) Prospect (BHP) and about 35km from the main Yeelirrie deposit (BHP), the
largest calcrete hosted uranium deposit in the world (Figure 4). The project is located
approximately 60km west of Mt Keith. The licence contains a roughly 7km x 2km sized
radiometrics anomaly (U, U/Th ratio) of moderate strength.
E59/1628 covers an 8km x 1.5km radiometrics U anomaly within a prominent paleo-channel
(Figure 5). The tenement is located immediately north of the Mullewa Yalgoo Road, just
14km west of Yalgoo. The interpreted paleo-channel drains granites with a very strong
radiometric response (U, Th).
E29/734 covers a 14km x 4km radiometrics anomaly (U, U/Th ratio) within a tributary to the
Lake Barlee drainage system (Figure 6). The project is located approximately 130km north
west of Menzies. This tenement has had previous drilling completed, with results of up
1000ppm U over 1m from drilling completed by ASARCO in 1973 (WAMEX report No. 7278).
More recent drilling was completed by Uranium Equities Ltd in 2007, with 13 holes reported
to contain greater than 100ppm U in gamma ray logs, with a best result of 1.9m @ 347ppm U
(Uranium Equities Ltd, ASX Quarterly report, December 2007). Drilling was reportedly along
the lake margin, with the centre of the lake still untested.
All of the tenements described are still in the application stage. Once granted, Alamar plans
to undertake ground geophysical surveys and possibly drilling to test these targets.
