    Further High-Grade Copper and Silver intercepts at Mount Oxide
    Perilya Limited (ASX: PEM) is pleased to announce continued exploration success from drilling at the Mount Oxide
    copper and cobalt project in the Mt Isa region in Queensland.
    Perilya’s latest round of drilling has confirmed further highly encouraging high grade copper and silver intercepts that
    extend at depth and below the current resource.
    The high grade intercepts returned from deeper drilling in drill hole MOXD104 (Figure 1) included:
    • 17m at 4.2 % copper from 248m,
    • 32m at 4.5 % copper (uncut) from 287m,
    • 12m at 15.3 % copper (uncut) and 161 g/t of silver from 345m.
    MOXD104 was drilled approximately 30 metres south of drill hole MOXD089, which previously reported (5th June 2008) drill
    intercepts including 31m at 6.2% copper from 346m and 23m at 8.9% copper from 395m.
    Perilya’s Executive Chairman, Patrick O’Connor, said our new drilling results, which included 12m at 15.3% copper from
    345m, were primarily below the current resource. They also further demonstrate the continuity of mineralisation along
    replaced sedimentary horizons and the excellent potential at depth.
    “A further hole MOXD105 has also intercepted good visual mineralisation 90m south of the initial intercept and results
    are pending.”
    “All these results bode well for the commercialisation and development process, which has commenced, with a number
    of overseas and Australian parties formerly expressing interest in participating in the further development of the Mount
    Oxide copper and cobalt project either in partnership with Perilya by way of joint venture, or through outright purchase of
    the project.”
    “The continuation of the high grade zones at depth and outside the current resource adds to the project and further
    demonstrates its potential,” he added.

    Mount Oxide Copper and Cobalt Project - Drill Program and Results
    In April, a program of diamond drilling commenced with two rigs targeting extensional mineralisation to the north and at
    depth of the current Mount Oxide resource.
    Drill hole MOXD104 was targeted to investigate potential at depth around the recently released high grade intercepts
    from MOXD089 and to understand the geology and plunge of mineralisation. Hole MOXD104 was drilled immediately
    south of the MOXD089 intercepts within approximately 30m and at a slightly higher elevation and has intersected
    replaced sedimentary horizons with strong hematite alteration associated with a structurally complex zone.
    Mineralisation is hosted in brecciated sediments and consists of coarse veins of bornite and chalcocite. The high grade
    zone is interpreted to be a structural intersection at depth off cross cutting structures and a parallel structure to the main
    mineralised fault. Lower grade zones between contain strong haematite alteration. The high silver grades are also of
    significant interest in this deeper zone. The intercepts are interpreted to be oblique to the mineralisation and interpreted
    to be at least 60% of true thickness.
    The significant intercepts from MOXD104 include:
    • 17m at 4.2 % copper from 248m,
    • 32m at 4.5 % copper (uncut) from 287m,
    o which includes 1m @ 21.3 % copper from 306m, and 2m at 24.3 % copper from 312m,
    • 12m at 15.3 % copper (uncut) and 161 g/t of silver from 345m
    o which includes 5m at 33.0 % copper from 345m
    Previously reported (5th June 2008) significant intercepts from drill hole MDOX089, include:
    • 22m at 6.3 % copper and 0.3 % cobalt from 258m
    • 19m at 3.7 % copper from 315m
    • 31m at 6.2 % copper from 346m
    • 23m at 8.9 % copper from 395m
    Further follow up drilling at depth is also providing significant encouragement with recent hole MOXD105 intersecting
    good visual mineralisation approximately 90m south of the MOXD89 intercept in a similar geological setting again
    demonstrating a plunge direction and continuity at depth, the results are still pending.
    Results are also reported from holes drilled north and above the MOXD89 intercept that contained only altered zones
    demonstrating the geological complexity in the zone.
    These mineralised copper zones at depth are outside of the current resource, which is very encouraging for the addition
    of significant high grade resources at depth.
    A track mounted rig has recently arrived on site and is testing some of the steep topographic zones north of the planned
    open pit to test at shallow depth below outcropping copper mineralisation. Good visual mineralisation has been noted
    during logging with the results still pending from this drilling.

    Background to the Mount Oxide Project
    (100% owned)
    The Mount Oxide project is located in the
    Mount Isa region Western Succession that
    includes several major sediment hosted
    breccia copper deposits. The deposit was
    intermittently mined between 1920 and 1971
    by way of a small open pit and underground
    operation. The project lies 25 kilometres north
    of the existing Mount Gordon mine operated
    by Aditya Birla Minerals Limited.
    The deposit is a chalcocite dominated system
    associated with strong silica-hematite
    alteration and copper mineralisation
    developed on the margins of the hematite
    core. The mineralisation is hosted in a
    sedimentary package associated with a
    strong structural control along the northeast
    trending Mount Oxide fault and associated
    cross cutting faults.
