    Drilling starts on newly
    discovered copper target
    Highlights:-
    • Drilling starts on newly discovered copper target at Jackson
    Minerals’ Boolaloo Project in WA.
    • Surface mineralisation identified in intermittent outcrops over a
    strike of 350 metres, with the main zone between 10 and 22
    metres wide.
    • Rock chip sampling of visible surface mineralisation has
    returned results varying between 1.48% and 49.7% copper
    and up to 3.4 oz/t of silver.
    • An IP geophysical survey has identified a chargeable and
    conductive zone below the surface mineralisation, supporting
    the potential for sulphides at depth.
    Australian-based exploration company Jackson Minerals Limited (“Jackson” or the
    “Company”) (ASX: JAK) has started RC drilling at its Boolaloo Project in the Pilbara of
    Western Australia.
    This drill program is targeting five new prospects in the Minga Bore area, including
    Copper Strike, Rattler, Eagles Rest, Green Rock and the Lag Anomaly. Exploration work
    conducted at Copper Strike has already produced results which identify it as the priority
    target for this drilling program.
    The Copper Strike Prospect was located by field prospecting and is just off the eastern
    extremity of a large east-west copper geochemical anomaly called Rattler (see Figure 2).
    The main zone of this prospect is defined by intermittent east-west to northwestsoutheast
    trending outcrops over a strike length of approximately 350 metres with widths
    of between 10 and 22 metres. Multiple parallel zones of mineralisation to the north and
    south are less well defined, but the extent of identified mineralisation is approximately
    160 metres in the north-south direction.
    Visible copper mineralisation at the prospect is extensive, over widths not previously
    identified at Boolaloo. Nineteen rock chip samples of the mineralisation have been taken. Malachite rich sandstones and quartz breccias have returned results of between
    1.48% and 20.3% copper. Outcrops of massive chalcocite and malachite (for example
    0.5 to 1 metre wide zones marginal to quartz veining) have returned between 16.2% and
    49.7% copper. The average result for all samples is 12.7% copper.
    Accessory metals such as silver and lead are also noted. Silver up to 3.41 oz/t,
    averaging 0.5 oz/t; and lead up to 6.12%, averaging 0.34%.
    Although extensively oxidised and dominated by copper secondary minerals, primary
    copper sulphides (chalcopyrite) have been located on the surface.
    An IP ground geophysical survey is currently in progress at the Copper Strike prospect.
    Preliminary results suggest there is a chargeable and conductive anomaly below the
    surface mineralisation. Considering the host rocks have been described as a
    monotonous pile of sandstones, such anomalism supports the potential for sulphides at
    depth.
    The proposed drilling at Boolaloo includes 15 holes for approximately 1,600 metres.
    Five prospects are being tested including Copper Strike, Rattler, Eagles Rest, Green
    Rock and the Lag Anomaly. Six holes have been planned for the Copper Strike
    prospect.
    The drilling at Boolaloo will be interrupted due to prior commitments for the drilling
    contractors. However, it is expected all holes will be completed by 20 July 2008.
    Final assay results are expected by early August, although significant results will be
    released to the market as they become available throughout the program.
