Encouraging Copper, Cobalt and Molybdenum Assays – Cethana,...

Encouraging Copper, Cobalt and Molybdenum Assays – Cethana, Tasmania 4th September 2008, Melbourne: Pluton Resources Ltd (“Pluton”) (ASX: PLV) is pleased to announce that final assays have been received from the two diamond drill
holes (CETD1 and CETD2) drilled earlier this year at Cethana in Tasmania (EL29/2006).

Results are as follows:

• Several broad intervals of anomalous copper mineralisation were intersected by the first diamond drill hole, CETD1, into the Cethana airborne magnetic anomaly.

• The best intersection grades 5m @ 0.21% Copper, 0.13 grams per tonne Gold, 4 grams per tonne Silver, 144ppm Molybdenum and 137ppm Cobalt from 213m down hole.

• Broader intersections in CETD1 such as 18m @ 0.1% Copper, 120ppm Molybdenum and 73ppm Cobalt from 245m highlight the potential for a bulk tonnage mineralising system.

• Narrow intervals identified within CETD2 have similar levels of mineralisation. Substantial zones of copper enrichment within the volcanic host are consistent with a
proximal porphyry target.

To date, two strongly chargeable zones have been defined by ground geophysics (Induced Polarisation or IP) within the very large aeromagnetic anomaly.

Neither of these chargeable and magnetic zones have been adequately drill tested by the two hole diamond program and remain outstanding drill targets for porphyry style mineralisation.

CETD1 and CETD2 (approximately 150m apart) were the first diamond drill holes into the very large (1.5kmx1km) Cethana magnetic anomaly. CETD1 drilled into the centre of
the aeromagnetic anomaly and CETD2 drilled into the peak ground magnetic anomaly.

The recent IP survey defined chargeability anomalies adjacent to these peaks and coincident with the broader aeromagnetic footprint. These prospective zones have not yet
been tested by drilling.
