Burt Plain Project
This project comprises one exploration licence,
EL25338, of about 800 sq kms which is located
40 kms north of Alice Springs. The area of interest
was originally identified as an iron ore prospect from
government aeromagnetic data.
Western Desert Resources Ltd and NuPower Resources
Ltd entered into the “Bushy Park” joint venture on
5th February 2008. NuPower Resources Ltd can earn a
51% interest in energy minerals on the tenement by
spending a total of $1,000,000 on this EL and Mueller
Creek EL25658 within three years. The tenement area
includes outcrop of high grade metamorphics of the
Palaeoproterozoic Arunta Block.
Interpretation of government aeromagnetic and gravity
information shows anomalies indicative of a huge iron
oxide system. Gravity and induced polarisation (IP)
surveys carried out last year at the Capricorn prospect
confirmed the likely presence of significant amounts
of sulphides and iron oxides.
This suggested possible targets of commercial interest
include Olympic Dam style IOCG deposits or nickel
sulphide deposits of the Voisey’s Bay or Norilsk type.
Five holes were drilled on various gravity, magnetic
and IP anomalies within the Capricorn Prospect for a
total of 1,832.5 metres.

Weak, deep IP anomaly |
The holes intersected mafic gneisses from shallow
depth with a consistent magnetite content of about
10%, which explains the observed magnetic and gravity
anomalies. All holes also intersected substantial
intervals of pyrite, which is clearly the source of the IP
responses. Drill core samples were analysed for a
suite of elements. Base metals, precious metals and
uranium values were uniformly low.
Significantly, all holes show enrichment in vanadium
with weak associated cobalt, nickel and barium values.
Better vanadium intersections are shown below:
It is postulated that the vanadium is associated with
magnetite. Vanidiferous magnetite occurs in many
gabbroic bodies worldwide and is mined in South Africa
and Russia. Vanadium is an essential element in the
composition of certain types of specialised steel.
Further exploration will be required to determine
whether zones of higher magnetite content occur within
the mafic gneisses. Any magnetite-rich zones could
be expected to contain higher and possibly economic
vanadium values. A detailed airborne magnetic survey
is planned to determine targets for further drilling.

During 2008 exploration work on the tenement included:
• Acquisition of airborne EM data over the
tenement using the Tempest system.
• Acquisition of gravity data over the western
part of the tenement in conjunction with the
NT government’s regional gravity program.
• Collection of water samples from six bores.
Following interpretation of the EM data, drilling may be
undertaken by NuPower Resources for palaeochannel
uranium deposits. |
