AUSTRALIA’S IDENTIFIED MINERAL RESOURCES <strong>2005</strong><br />
■<br />
Drilling by Thundelarra Exploration Ltd and Sally Malay Mining Ltd at the Copernicus North<br />
prospect in East Kimberley intersected a broad zone of <strong>mineral</strong>isation that included intersections<br />
grading 1.36% Ni, 0.87% Cu and 0.05% Co over 17 m from 199 m; and 1.45% Ni, 1.16% Cu and<br />
0.05% Co over 14 m from 260 m.<br />

Western Areas NL reported an intersection of 44.2 m at 3.74% Ni at the T1 deposit being<br />
developed at Flying Fox and another intersection of 34 m at 4.4% Ni was announced in February<br />
<strong>2005</strong> for the deeper T5 deposit.<br />
Exploration drilling by Jubilee Mines NL in 2004 included intersections of 4.6 m at 9.2% Ni at<br />
Prospero and 5.85 m at 7.93% Ni at the Alec Mairs deposit. These results were followed by very<br />
substantial intersections at the Prospero deposit and included 30.5 m at 7.6% Ni in <strong>2005</strong>.<br />
LionOre Mining International Ltd reported that drilling a new and a previously untested geological<br />
setting confirmed the presence of a shallowly dipping pyroxenite hosted Ni-Cu-Pt-Pd-Au-Co<br />
<strong>mineral</strong>isation at Billy Ray prospect in the Lake Johnston project. Intersections included 43 m at<br />
0.61% Ni, 0.31% Cu, 0.38 g/t Pt-Pd from 2 m; and 29 m at 0.49% Ni, 0.15% Cu, from 79 m<br />
including 2 m at 3.13% Ni, 1.21% Cu, 0.62% Co and 0.56 g/t Pt-Pd from 79 m.<br />
LionOre also reported intersections from a newly discovered prospect, The Horn, 8km west of<br />
Thunderbox; 9.95 m at 0.98% Ni and 0.21% Cu from 133.05 m, including 1.55 m at 2.34% Ni and<br />
0.37% Cu from 133.05 m; and 9.85 m at 0.79% Ni and 0.24% Cu from 110.15 m including 0.30 m<br />
at 2.03% Ni and 0.17% Cu from 110.15 m.<br />
In a joint venture with Pioneer Nickel Ltd, Jubilee Mines NL completed a 2 900 m reverse<br />
circulation drilling program at the Acra Joint Venture Project, which returned 40 m at 0.57% Ni<br />
and 242 ppm Cu. Further drilling was commenced in <strong>2005</strong>.<br />
At Anomaly 11, 20 km south of the Blair Nickel Mine, an 18 RC hole drilling program by<br />
<strong>Australia</strong>n Mines Limited confirmed previous nickel intersections and included 2 m at 2.25% Ni<br />
within 10 m at 1.25% Ni.<br />
Titan Resources Ltd reported intersections of 5 m at 2.11% Ni and 6 m at 3.29% Ni obtained from<br />
a drilling program to confirm nickel <strong>mineral</strong>isation from previous drilling on the mafic-ultramafic<br />
contact below open pit at Munda.<br />
In early 2004, Barra Resources Ltd reported an intersection of 42 m at 1.12% Ni and 0.059% Co<br />
from 10 m depth in the saprolite zone of weathered ultramafic rocks (Martins Zone) at the<br />
Riverina project, 130 km north of Coolgardie (WA). The oxide nickel saprolite zone has a possible<br />
strike length of 1 km. Follow up drilling to test the basal footwall contact of the ultramafic<br />
sequence intersected 4 m at 0.7% Ni from 144 m at the footwall of fresh ultramafic rocks. Further<br />
drilling of down hole electromagnetic anomalies in the first half of <strong>2005</strong> led to the discoveries of<br />
massive and disseminated nickel sulphides at the Riverina Joint Venture project area including<br />
31 m at 1.17% Ni, 618 ppm Cu and 105 ppb Pl, and 1.14 m at 2.28% Ni and 315 ppm Cu.<br />
At Barrow Creek (NT), Mithril Resources Ltd (in a joint venture of BHP Billiton, Goldstake<br />
Exploration Inc and Imperial Granite and Minerals Pty Ltd) reported nickel, copper and silver<br />
<strong>mineral</strong>isation over a strike length of 800 m with the better intersections of 0.35 m at 8.27% Cu,<br />
1.22% Ni and 26.2 g/t Ag at a depth of 110 m; and 0.6 m at 2.27% Cu, 2.86% Ni, and 8.5 g/t Ag at a<br />
depth of 170 m. BHP Billiton withdrew from the joint venture in early <strong>2005</strong> and Mithrill entered into<br />
an option and Joint Venture agreement with Falconbridge (<strong>Australia</strong>) Pty Ltd to explore and develop<br />
nickel sulphide deposits within the Barrow Creek Project. Drilling is to commence in May <strong>2005</strong>.<br />
GME Resources Ltd announced in March <strong>2005</strong> upgraded <strong>resources</strong> from their infill drilling of their<br />
Mt Kilkenny and Eucalyptus lateritic deposits amounting to 18.55 Mt of indicated <strong>resources</strong> at<br />
1.27% Ni and 0.1% Co, and 22.31 Mt of inferred resource at 1.23% Ni and 0.1% Co at a cut off<br />
grade of 1% Ni. High grade intercepts from the infill drilling included 16 m at 1.575% Ni and<br />
0.142% Co at Mt Kilkenny; 11 m at 1.92% Ni and 0.111% Co at Eucalyptus Central; and 7 m at<br />
1.751% Ni and 0.131% Co at Camelback.
