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.

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.

Chairman

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.
