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.

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.

Page 8: POOCHERA KAOLIN PROJECT · 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

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 much more expensive Titanium Dioxide (TiO2)

• It provides opacity, brightness & whiteness

• It helps to prevent settling in stored paints

KAOLIN TYPES

HYDROUS KAOLIN

Produced by the wet processing of kaolinised granite, involving:

• Mixing with water;

• Screening:

• Classifying;

• Drying, crushing and grinding.

CALCINED KAOLIN

Produced by heating hydrous kaolin to ~1000oC.

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.

* The term “Exploration Target” should not be misconstrued as an estimate of Mineral Resources and Reserves as defined in the JORC Code (2004), and the term has not been used in that context. The term is conceptual in nature and it is uncertain if further exploration will result in the determination of a Mineral Resource. Refer Clause 18 of the JORC Code (2004).

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.

INFRASTRUCTURE ISSUES

WATER: Low salinity processing water required: desalination of

seawater is an option. Other options are being considered.

POWER: Grid or generated on site.

TRANSPORT: Road and/or rail.

PORTS: Thevenard would require modification to allow container

loading. Otherwise Port Adelaide is currently the closest

container port.

COMMUNITY ENGAGEMENT

MINOTAUR’S PRINCIPLES

• Employ local people and service providers whenever possible.

• Pay service providers promptly.

• Provide training for our employees.

• It’s all about trust! Keep local landholders fully informed of pending

activity and results of work (as much as allowed by the ASX). Listen to

landholders and deal effectively with any concerns.

• Inform local Councils as much as possible about the project and seek

their cooperation.

• Keep nearby communities informed. Be prepared to talk to people.

• Ensure that our employees and contractors respect the local

community.

• Be a part of the local community.
