Ann: Irvine - Isthmus diamond drilling assay resu, page-7

re: Ann: Irvine - Isthmus diamond drilling as... Good to see this is the 100% focus now:

Hardstaff Peninsula
Diamond drilling has recommenced at the Hardstaff Peninsula on drill hole 11DDH107 at site Y2‐15
(Figure 2).

Drilling is to be completed on a maximum of four drill sites within the zone of Inferred Mineral
Resources located in the central Hardstaff Peninsula. Two diamond drill holes, 11DDH091 (resource
definition) and 11DDH092 (environmental monitoring) have been completed within this zone. Drill core
from both holes has been logged, cut and sampled and dispatched for assay.

At the completion of diamond drilling within this zone, it is expected that a proportion of the Inferred
Mineral Resources will be converted to an Indicated Mineral Resource category following receipt of
assay data, completion of resource modeling and further technical studies. Pluton expects this will
enable the Stage 1 Ore Reserve estimate to be expanded to include more of the Indicated Mineral
Resource defined in the north of the Hardstaff Peninsula, thereby increasing the Ore Reserve base and
mine life of the Project.

The Hardstaff Peninsula is the proposed site of an initial 11 year mining operation producing 40 Mt of
saleable concentrate generating revenues in excess of A$5.6 billion as defined in the Pre‐Feasibility
Study for Stage 1 (ASX announcement, 6th June 2011).
