UPDATE DRILLING REPORT ON AIRSTRIP COPPER AND
DIBETE PROSPECTS
Extension to Discovery at Airstrip Copper Prospect,
Botswana
The Board wishes to update the market on its recent drilling program at
the above two prospects:- At the Airstrip Copper prospect, a step out
diamond drill hole, (ACRD 029) from the discovery hole (ACRC003)
previously announced (ASX release dated 3 February 2010) has resulted
in an intersection of massive bornite rich copper sulphides over an
interval of 0.25 metres. Bornite has a theoretical composition of
Cu5FeS4 which contains 63.3% copper.
Extensive analysis of the intersection and of a coppper bearing standard
material by a Niton portable XRF analyser has indicated that the
intersection has high grades of copper and silver. The diamond core will
need to be sent to a laboratory for analysis to confirm the copper and
silver grades.
Modelling of the intersection position has been carried out and it can
now be seen that the previous intersections in holes ACRC 003, 6 and 10
and the current intersection are likey to be part of a single relatively
planar sheet of mineralisation.
The current intersection was drilled at 325 degrees, at a conductor
interpreted from the Company’s recent Gradient Array and Dipole-
Dipole IP surveys through the Airstrip Copper prospect area.

The mineralisation is interpreted to be a thin massive sulphide zone with narrow
veins and disseminated sulphides in the immediate host rocks particularly in the
partly bleached and altered footwall to the mineralisation. The tenor of this
mineralisation cannot be assessed at present but is expected to result in a broader
intersection of mineralisation of about 0.5 metres thick.
A second intersection has subsequently been made approximately 10 metres
vertically above the intersection in ACRD 029 in hole ACRD030. This intersection
contains 0.58 m of silver bearing bornite rich mineralisation from 55.72-56.30
metres. No detailed work has yet been carried out on this intersection or its
immediate host rocks.
The following plans show the relationship between all the holes drilled in this area
including those holes that failed to intersect mineralisation.

Plan of drill holes and conductor targeted in ACRD029
The Company’s aim of gaining a better understanding of the results of the previous
drilling program, where hole ACRC003 intersected a 3 metre interval of 22% copper
and 33 ounces silver (as shown below), is being achieved.
11m @ 7.63% Cu, 462 g/t Ag from 52m
Incl 7m @ 11.81% Cu, 717g/t Ag from 52m
Incl 3m @ 22.74% Cu, 1379g/t Ag from 53m
With a far better understanding of both the geology and geophysical characteristics
of the mineralisation, a program of step out holes is now in progress. Samples will
be dispatched to the laboratory when detailed logging and core splitting has been
completed.

DIBETE PROSPECT
The Company is also working on a series of additional prospects, with visible copper
mineralised intersections being found at Dibete Copper prospect in holes DBRD 001,
4, 5 and 6, with holes 9-12 not yet completed. The plan below shows the location of
the drill holes in relation to a large zinc anomaly and to previously interpreted
conductor axes interpreted from ground EM surveys.

The RC samples are currently being assayed and results will be released to the
market as soon as they are available.

OTHER TARGETS
A series of high quality targets have also been interpreted from a combination of old
data and new IP surveys at other prospects, including Mmatsiane and Mashambe.
These prospects are now drill ready. Work is continuing on additional targets which
will also be tested by drilling.
Results from drill holes on each of the project areas will be made available to the
market as they are received and interpreted.

Note: The Airstrip Copper (PL110/94), Dibete (PL111/94) Mmatsiane (PL54/98) and
Mashambe (PL54/98) tenements are subject to a Section 17 extension under the
Botswana Mines and Minerals Act on the basis of a new discovery.
The information in this report that relates to Exploration Results is based on information
compiled by Mr. Peter Temby, a consultant employed by Anpet Exploration Pty Ltd and a
member of The Australian Institute of Geoscientists. Mr. Temby has sufficient experience that is
relevant to the style of mineralisation and type of deposit under consideration and to the activity
which he is undertaking to qualify as a Competent Person as defined in the 2004 Edition of the
Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves.
Mr. Temby consents to the inclusion in this report of matters based on his information in the
form and context in which it appears.
