Spring Hill
Spring Hill is located in the Pine Creek Gold Field,
150 kms south of Darwin. The tenement package
comprises an 1035 ha Mining Lease, ML23812,
surrounded by the 36 sq kms Exploration Licence,
EL22957. Western Desert Resources Ltd has 100%
interest in the tenements.
The project area is in the southern part of the
Palaeoproterozoic to Mesoproterozoic Pine Creek
Geosyncline, straddling a regional shear zone, the
Pine Creek shear. The shear is related to a
number of significant gold deposits in the region.
The area has also been identified as prospective
for tin mineralisation.
Exploration work completed on the EL and ML includes:
• Acquisition of SkyTEM airborne EM data over the
EL area on 150 metre spaced flight lines.
• Purchase of Satellite imagery (Quickbird VHR) for
the Spring Hill EL area.
• Office studies including database compilation,
literature research, drill section output and
planning for future drilling programs.
• The previous metallurgical testwork carried
out by Ross Mining NL has been reviewed by
Bemex Corporation.
Results from the SkyTEM EM survey were received in
September. The survey defined one stand-out anomaly,
a conductor one kilometre long adjacent to the old
Horseshoe tin mine. Geologically, the conductor is
located in the Koolpin Formation, which contains
carbonaceous facies. The nature of the conductor and
possible associated mineralisation will be investigated
by a program of geological mapping, surface sampling
and drilling.

At the Spring Hill gold deposit a database was compiled
containing all of the previous drilling information.
Studies of the drill hole sections showed that the gold
mineralisation was erratic and that higher grade
zones could rarely be traced between section lines
25 metres apart.
Initial results from the metallurgical testwork by
Ammtec indicate that the Bond ball mill work index is in
the typical range for oxide gold ore and has a moderate
value. The results also indicate that SAG milling could
be considered as an option.
The proposed exploration programme for the Spring Hill
gold deposit in 2008-2009 will include a scoping study
covering the metallurgical and processing aspects of any
development and further geological studies. Depending
on the results of this work further exploration drilling
may be undertaken.
