The presentation must be considered in the light of these uncertainties and investments in AusAmerican should be considered as speculative in nature. The presentation is not a prospectus or similar disclosure document and does not constitute an invitation to apply for shares. Statements relating to potential quantity and grades of exploration targets in this presentation are conceptual in nature as there has been insufficient exploration to define a mineral resource and it is uncertain whether further exploration will result in the determination of a Mineral Resource

Competent Person. The review of exploration activities and results contained in this presentation in relation to the Company’s projects is based on information compiled by Mr. Richard Holmes.

Mr. Holmes is a Member of the Australasian Institute of Mining and Metallurgy and has sufficient experience which is relevant to the style of mineralization and types of deposits under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the December 2004 edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the JORC Code). Mr. Holmes consents to the inclusion of this information in the form and context in which it appears in this presentation.

Cautionary note

The potential quantity and grade stated in the Exploration Target is conceptual in nature and there has been insufficient exploration to define a Mineral Resource. It is uncertain if further exploration will result in the determination of a Mineral Resource. The exploration target is based upon a combination of historical mining information (geological plans, sections and limited underground drilling/sampling) and surface geological mapping of the prospective horizon.

Bluebell Exploration Target

• Initial exploration target “open pit” concept

• 15 – 20 million tonnes at 0.6 – 0.8% copper, 0.2 – 0.4 g/t gold and 15 – 30g/t silver*

• Intersected in numerous workings/underground drill holes

• Based on historical records and reports

• Mine plans

==> picture [175 x 98] intentionally omitted <==

==> picture [302 x 204] intentionally omitted <==

• Limited underground drilling and sampling

• Brownfields exploration rather than greenfield exploration

• *The potential quantities and grades presented are conceptual in nature, there has been insufficient exploration to define an overall Mineral Resource and it is uncertain if further exploration will result in the determination of a Mineral Resource
