    Massive Sulphides Intersected in Diamond Core Drill Hole DODH255
    Diamond core drill targeting of Induced Polarisation (IP), chargeability targets adjacent to, and north of the Las Minerale and Northern Siltstone Orebodies, has intersected numerous zones of sulphide mineralisation, including the copper mineral chalcopyrite (chalcopyrite contains approximately 34.6% Cu).
    The most recent drill hole to test this new mineralised zone (DODH255), was designed to follow up on the exploration success of diamond drill holes DODH236 and DODH253, both of which successfully tested a large ?football-shaped? Induced Polarisation (IP), chargeability-high anomaly, in an area that has not been

    tested in previous drilling campaigns at Rocklands.
    Diamond drill hole DODH253 was the second drill hole to test this area, was designed to scissor-test mineralisation identified in drill hole DODH236, and intersected a number of chalcopyrite occurrences indicating at least two separate mineralised zones exist in this area. Additionally, a zone of semi-massive chalcopyrite was intersected at 390m, suggesting a third mineralised zone may have also been identified at depth.
    Diamond drill hole DODH255, which is currently drilling at approximately 260m, is the third exploration hole to test this area and is designed to follow up on the semi-massive sulphides intersected in drill hole DODH253. This hole has intersected a zone of massive sulphides, within a zone of chalcopyrite

    mineralisation from 143-147m, in a previously un-tested area. Additionally, the hole has intersected significant chalcopyrite mineralisation from 222-229m, 232-240m, and 252-256m.
    This hole is yet to reach the required depth to test the interpreted continuation of semi-massive chalcopyrite mineralisation intersected in DODH253.
    These newly identified zones of chalcopyrite mineralisation occur between the Northern Siltstone and Rainden Orebodies (see fig 3), both to the local grid north of Las Minerale. The new area of mineralisation is located between zones currently included in the Rocklands Group Copper Project resource inventory, and strikes sub-parallel to the Company?s flagship Las Minerale Orebody.
    This new discovery underlines the prospective nature of the Rocklands EPM, in spite of over 300,000m of drilling conducted to date, and highlights the potential for increasing the Rocklands resource inventory identified in the May 2011 Resource Estimate.
    Approximately 20 new exploration targets are currently being investigated, based on one or more of the numerous geophysical surveys carried out over the Rocklands tenement (EPM13049), and surface

    geochemical results from soil and bedrock drill samples.
    Geophysical surveys in our database include SAM (Sub-audio Magnetics), Airborne Radiometrics, Aerial and Ground Magnetics, Induced Polarisation (IP), and Gravity Surveys. The programmes are ongoing and are consistent with the company?s intention to drill out the entire Rocklands tenement.
    This new discovery will now be followed up with a series of diamond holes to test the strike and dip of the identified zones of mineralisation, which are interpreted to be oriented similarly to the Las Minerale, and Northern Siltstone ore bodies.
    Yours faithfully
