Uranium
During April 2005, farm-in partner Quasar
reported that reconnaissance drilling at the Beverley 4 Mile Prospect
intercepted uranium equivalent mineralization.
The drilling targeted sands with potential to host uranium
mineralisation within the ‘Paralana High Plains’, east of the Northern
Flinders Ranges in an area 5 to10km west of the Beverley Uranium Mine
(Figure 5A). It has been suggested that the uranium at the Beverley
Uranium Mine was sourced from weathering of the Mt Painter highlands to
the west. A total of 65 rotary mud drill holes totalling 4,857m have
been completed, additionally two drill holes (AK002 and AK010) had 3m
diamond core tails taken of basement volcanics.
All holes were logged using down hole geophysical probes including a
gamma ray log which is used to calculate equivalent U3O8 grades and
recently a Prompt Fission Neutron (PFN) tool has been used to verify the
presence of uranium mineralisation in selected holes. All holes were
drilled vertically to intersect carbonaceous units within the Tertiary
sedimentary sequence unconformably overlying weathered Proterozoic
basement.
Drilling to date has identified two distinct mineralised zones.
The highly encouraging uranium equivalent results included:
Western Zone
13.5 m @ 0.440 %e eU3O8(1) (including 5.0 m @
0.801 % eU3O8(1))
3.5 m @ 0.562 % eU3O8(1)
4.5 m @ 0.405 % eU3O8(1)
6.0 m @ 0.230 % eU3O8(1)
8.0 m @ 0.137 % eU3O8(1)
Eastern Zone
5.5m @ 0.40 % eU3O8(1)
1.5m @ 0.26 % eU3O8(1)
1.0m @ 0.20 % eU3O8(1)
1.0m @ 0.16 % eU3O8(1)
5.0m @ 0.15 % eU3O8(1)
(1) - eU3O8 refers to equivalent grade U3O8
as estimated from a gamma-ray log
Follow-up geochemical analyses of two metre samples drilled in the
mineralised holes were received in the second half of 2005. The results
indicated anomalous uranium values (up to 2,550ppm in AK019) were
generally coincident with the zones previously reported as containing
anomalous radioactivity as measured by down hole gamma-ray logging.
Thorium values throughout the mineralised zones reported at background
or near background values (<30ppm Th). These analyses confirm the
radioactivity as being due to uranium.
Coarse sands are widespread and thickly developed above a regional
unconformity developed at the top of presumed Proterozoic basement
rocks. These sands frequently show limonite staining suggestive of an
oxidising event that may be related to roll front movement down-dip to
the northeast. The geology of the Paralana High Plains differs from that
encountered to the east at the Beverley Uranium Mine. Mineralisation at
the Beverley 4 Mile Prospect is considered to occur at, or over a
disconformity between, the early Cretaceous Bulldog Shale and the
overlying Eocene Eyre Formation. Importantly, the Eyre Formation is the
host to known uranium deposits such as Honeymoon and Gould’s Dam.
Drilling results in the western extension area continued to provide
highly encouraging results with the majority of holes intersecting
uranium mineralisation The known areal extent of the mineralisation is
currently 1.6km by 1.2km, but the mineralised zone has not been closed
off by drilling. The depth to basement is relatively uniform with depths
commonly between 160m and 190m indicating that there are no major
structural controls within this mineralised zone.
Quasar is planning an extensive drill campaign for 2006. Additional work
to define groundwater quality, mineralogy and metallurgical
characteristics will also be undertaken.

Copper-Gold
At the M2 target area adjoining the old Yudnamutana Mining Field in the
south west of the tenement, 19 rock chip samples were collected over 5
of the initial geophysical targets. Assay results of rock chip samples
returned anomalous gold and copper geochemistry (250 to 350 ppb gold and
1 to 20% copper) from three samples and one sample returned 10 ppm gold
and 4% copper. Four sites were selected for the initial drill programme
to test for IOCG (iron oxide-copper-gold) style copper gold
mineralisation. Quasar has received a PACE grant (Plan for Accelerating
Exploration) from the South Australian Government. This will fund a
portion of the drilling costs on one of the base metal targets.
Quasar has reported that RC pre-collars were drilled, and diamond
drilling has commenced at M2 target in January 2006.

Maldon Gold Project, Victoria (Alliance 100%)
History
The Maldon Goldfield is the next most productive reef goldfield in
Victoria after Bendigo, Stawell and Ballarat. From 1854 to 1926, records
indicate total primary production of 1.75 million ounces of gold at an
average recovered grade of 28 g/t.
Alliance listed on the ASX as Alliance Gold Mines NL in 1994 after it
purchased the Maldon Gold Project from Triad Minerals, including a fully
permitted and an operational gold treatment plant, 3km northeast of
Maldon. From 1988, the previous owner produced over 55,000 ounces of
gold from the Union Hill open pit. Between 1994 and 1998 considerable
drilling was undertaken, mainly along the Eaglehawk Reef and mining
continued in the open pit. A decline was commenced from within the open
pit to explore Eaglehawk and Linscotts reefs, and then head south to
access other reefs adjacent to the town of Maldon. The decline was
suspended in 1997 in a climate of falling gold prices. Scalping and
limited surface mining operations were conducted in the open pit in
1998/99.
In October 2003, Alliance attracted a new major investor and Alliance
underwent changes to its Board, changed its name to Alliance Resources
Ltd and $2.45 million was raised in funding via a non-renounceable
entitlement issue to re-invigorate the Maldon Gold Project.
Geological Review
A geological review of the Maldon Goldfield commenced in December 2003
and was completed during June 2004. The review focussed on a 3km by 1km
corridor hosting the majority of Maldon's historic gold production. The
resulting database was used to produce digital model of historical
mines, major quartz reefs and associated ore shoots. This work relied
heavily on geological mapping by 19th century government geologist R.A.
Moon and mine managers’ reports in the local newspaper. Further research
on the position of quartz reefs and ore shoots from mine managers’
reports in the local newspaper was then added to the database. The
review and subsequent digital modelling showed the five major reefs to
have good structural continuity. It identified 10 target areas,
including possible extensions to the known reefs and possible new ore
shoots.
The review has highlighted structural continuity within five major reef
lines and Alliance has identified 10 target areas to date, including
possible extensions to existing reefs as well as possible new ore
shoots.
Targets are high-grade gold lodes of plus 30,000 ounces, which are
relatively short in strike length but persistent down plunge.

Exploration
Since 2004, Alliance has undertaken diamond drilling of targets
generated by the geological review of the Maldon Goldfield. Exploration
to date has identified potentially mineable mineralisation in Eaglehawk
Reef at Alliance South Prospect.
The first drill holes at Alliance South Prospect (Figure 2) confirmed
the structure as predicted by the geological model and produced several
encouraging intercepts. Step-out and in-fill drilling that has now
tested the reef with 32 holes for a total 8,487 m.

Several mineralised zones associated with Eaglehawk Reef have been
identified at Alliance South, however the dominant mineralised structure
occurs along the western margin of the main lode, close to the west
bounding fault or “wall”. The gold mineralisation is associated with two
moderately south-plunging flexures in the reef. The upper flexure
mineralisation displays continuity over plus 350m down plunge and both
flexures remain open along plunge.

Proposed Exploration and Mining
Alliance is now investigating an exploration decline to permit
extraction of a bulk sample for grade determination through Alliance's
treatment plant. If the results are positive, the Company will be well
placed for underground development. Underground development will also
provide access to some targets currently unable to be drilled from
surface at a reasonable cost.
In the longer term, Alliance plans to test the numerous remaining
targets generated by the geological review.
Operations
The treatment plant is currently on care-and-maintenance. Monitoring of
the rehabilitation areas at Maldon is ongoing.
