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: What is it and what is it used for?
Kaolin or White China Clay
Mineral: Kaolinite Al2Si2O5(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
RUBBER FILLER: >1 million tpa
FIBREGLASS: >1 million tpa
PLASTICS & POLYMERS: >0.5 million tpa
OTHER: Adhesives, sealants, inks, pharmaceuticals, cosmetics, horticulture
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.
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.
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).

PROPERTIES OF FOUR MINOTAUR KAOLIN PRODUCTS
CAREY’S WELL HYDROUS KAOLIN: SEM IMAGE
Nb. Very fine grain size and excellent hexagonal crystallinity
Rotary Calcining Kiln in operation March 2012
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.
