Where MEP expresses or implies an expectation ti or belief as to the success of future exploration and the economic viability of future project evaluations, such expectation or belief is expressed in good faith and is believed to have a reasonable basis. However, such projected outcomes are subject to risks, uncertainties and other factors which could cause actual results to differ materially from projected future results. Such risks include, but are not limited to, exploration success, product price volatility, changes to current mineral resource estimates or targets, changes to assumptions for capital and operating costs as well as political and operational risks and government regulatory outcomes. MEP disclaims any obligation to advise any person if it becomes aware of any inaccuracy in or omission from any forecast or to update such forecast. Information the following presentation that relates to Exploration Data and Mineral Resource Estimates for the Poochera Kaolin Deposits is based on information evaluated by Mr Lewis Barnes who is a Member of Australian Institute of Geoscientists and who has sufficient experience relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as Competent Persons as defined in the 2004 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the JORC Code ). Mr Barnes is a contract employee of Minotaur Exploration Ltd and he consents to the inclusion in the presentation of matters based on his information in the form and context in which they appear.

5 Kaolin or White China Clay KAOLIN: What is it and what is it used for? Mineral: Kaolinite Al 2 Si 2 O 5 (OH) 4 USES CERAMICS: Traditional (>4000 years) and ongoing use: >5 million tpa PAPER FILLING & COATING: >11 million tpa PAINT FILLER & EXTENDER: >1 million tpa and growing g RUBBER FILLER: >1 million tpa FIBREGLASS: >1 million tpa PLASTICS & POLYMERS: >0.5 million tpa OTHER: Adhesives, sealants, inks, pharmaceuticals, cosmetics, horticulture

6 KAOLIN IN CERAMICS Whiteware Sanitaryware Tiles Porcelain Bone China Vitreous China Glazes and Engobes Kaolin prices vary from ~$100 per tonne to in excess of $1,000 per tonne.

7 KAOLIN USES IN PAPER & PAPERBOARD Filling and Coating Applications Kaolin is used to fill and coat paper & paperboard: to produce an even, flat surface to provide a bright, white surface to provide a good surface for ink absorption High quality paper requires high quality (and priced) kaolin.

8 KAOLIN IN PAINTS Kaolin is used as an opacifier, a pigment and an extender in the manufacture of paint. This is a growing industry, especially in China. Kaolin is used as: A substitute for the more expensive Titanium Dioxide (TiO 2 ) It provides opacity, brightness & whiteness It helps to prevent settling in stored paints

9 KAOLIN TYPES HYDROUS KAOLIN Produced by the wet processing of kaolinised granite, involving: Mixing with water and dispersant (blunging) Wet screening Classifying (using cyclones and/or centrifuges) Pressing to produce filter cake Drying, crushing and grinding. CALCINED KAOLIN Produced by heating hydrous kaolin to ~1000 o C. This process removes water (~14%) from the crystal lattice of the kaolin, This process removes water ( 14%) from the crystal lattice of the kaolin, resulting in an amorphous material with even greater brightness and whiteness than the hydrous kaolin.

32 Pilot Plant Products and Marketing Strategy The Streaky Bay Pilot Plant has produced several hundred kilograms of three selected high quality hydrous kaolin products and seventy kilograms of premium quality calcined kaolin. An experienced kaolin marketing consultant has been engaged to advise on marketing strategy. Samples are being sent to selected potential clients around the world to enable them to test the suitability of Carey s Well kaolin for their particular applications. To date, samples have been sent to China, Korea, Indonesia, Thailand, Vietnam, Bangladesh, India, Italy and the UK. Initial target t markets include ceramics, paint and high h quality paper coating. Some early responses have been favorable and we expect to complete this market assessment within six months. In conjunction with this marketing strategy, Minotaur is actively seeking Investment Partners.

33 In summary, the Carey s Well Kaolin Deposit: Is very large (>50 year potential mine life), Appears to be very uniform in quality and distribution, Has all the qualities needed to produce high quality hydrous kaolin using conventional processing techniques, Demonstrates the ability to produce very high quality calcined kaolin, Is well located with a port at Thevenard within easy trucking distance, Has an excellent waste to ore ratio and could be mined using simple open cut mining processes.
