Technical Specialist's Report<br />

The Golden Orb deposit comprises a chert BIF unit enclosed by a sequence <strong>of</strong> basalt, high magnesium<br />

basalt, ultramafics and minor gabbro. The deposit has been interpreted to have developed in a dilati<strong>on</strong>al<br />

positi<strong>on</strong> al<strong>on</strong>g a strike-slip shear.<br />

The Die Hardy and Red Legs deposits are associated <strong>with</strong> BIF in c<strong>on</strong>juncti<strong>on</strong> <strong>with</strong> variably trending shear<br />

z<strong>on</strong>es. Similarly, gold mineralisati<strong>on</strong> at Mt King is interpreted to be c<strong>on</strong>centrated around the intersecti<strong>on</strong> <strong>of</strong><br />

cross cutting faults and the BIFs.<br />

The King Brown deposit is hosted in highly weathered ultramafic saprolitic clays interspersed <strong>with</strong> narrow BIF<br />

units.<br />

Complete oxidati<strong>on</strong> extends to between 45 m below surface and 80 m below surface and locally reaches<br />

depths <strong>of</strong> greater than 100 m.<br />

4.1.2.2 Southern Deposits<br />

Mineralisati<strong>on</strong> at the Battler Deposit is associated <strong>with</strong> <strong>on</strong>e major easterly-dipping north-trending shear z<strong>on</strong>e<br />

in c<strong>on</strong>juncti<strong>on</strong> <strong>with</strong> a major north-north-west-trending, steeply east-dipping splay shear z<strong>on</strong>e.<br />

British Hill mineralisati<strong>on</strong> is associated <strong>with</strong> BIF-hosted quartz veining associated <strong>with</strong> north-trending,<br />

subvertical shear z<strong>on</strong>es <strong>with</strong>in a mafic-ultramafic greenst<strong>on</strong>e sequence. Three main shears have been<br />

identified.<br />

4.1.3 Resources<br />

Mineral Resources for Marda at 25 September 2012 are listed in Table 4.1. AMC has independently<br />

reviewed the total t<strong>on</strong>nes and grade <strong>of</strong> the Marda Central, King Brown, Golden Orb, Barranco Opti<strong>on</strong>, British<br />

Hill and Battler Mineral Resource estimates and found no material differences when compared to the total<br />

t<strong>on</strong>nes and grade reported at 25 September 2012.<br />

Indicated and Inferred t<strong>on</strong>nes differ from those announced by Southern Cross <strong>on</strong> 23 November 2012. Southern<br />

Cross advised the Resource for British Hill was incorrectly reported and the values in the table above are correct and<br />

match those provided by Ravensgate.<br />

The following comments apply to all resources estimated by Ravensgate during 2012. The resource<br />

estimates are based mostly <strong>on</strong> diam<strong>on</strong>d and RC drilling.<br />
