Background Baris G. Yildirim MSc. in Mineral Processing (Hons) and Geologist PhD at University of Queensland

- He is very much integrated with the mining & exploration business in Turkey.

- Previously , He worked in project management at Teck Resources in Turkey and managed multiple exploration projects.

- Kirazli and Agidagi Projects

- Demir Project

- Kizildam Project

- Konya Inlice Project

- His work at Teck was awarded twice from his effort at Kirazli Gold project, as New Discovery and Best Work Proposal.

- Baris Yildirim worked as a project geometallurgist for Teck Metals in Canada, and executed an plant optimisation project between Highland Valley Copper Mine and the Teck research center.

- He has involved building two mines in his career in 10 years. One of them is underground Pb-Zn-Ag operation in South of Turkey and the second one is vermiculite operation in Central Anatolia.

Background II

5

Geometallurgy involves a quantified and

spatially constrained approach to ore

characterisation in terms of relationships

to critical processing performance

behaviours.

Geometallurgy complements but does

not replace existing approaches to

design and optimization of mining and

mineral processing operations.

What is Geometallurgy?

Geometallurgy requires integration

across a wide range of existing activities

- it includes aspects of process

mineralogy, mine geology, metallurgy,

process control, resource modelling,

geostatistics..

6

Primary aim is to provide more constrained inputs that reflect inherent

geological variability and its impact on machine-based process

parameters

e.g. hardness, comminution energy, size reduction, liberation, product

recovery.. Steve Walters, 2005

What is Geometallurgy?

Malcolm Powell, 2013

The application of a spatially modelled suite of geotechnical,

metallurgical and environmental attributes of an orebody to maximise

the value of a mining project, both in design and operation.

Tim Napier Munn, 2010

Steve Williams, 2004

What Geometallurgy

Aims to Deliver ?

Incorporation of geometallurgical

parameters into resource modelling to

supplement traditional geology and

grade-based attributes, enabling a more

holistic approach to economic

optimization.

Detailed geometallurgical models that

reflect inherent variability also aim to

reduce technical risk associated with

design and operation of mining

operations.

Geometallurgical information can be used

to optimize flow sheet design and

equipment sizing with a view to predicting

and optimizing plant performance and

production over life of project.

Deterministic geometallurgical models are

more effective than empirical

measurements.

Mission and Vision

Remains the Same

Famous Rosetta

Stone of Egyptian

archeology

One rock one language

Develop a sampling and testing strategy that can be

more effectively used to define

and asses geometallurgical

variability.

Use technology as a driver for change.

Bridge the cross discipline divide between the various

professions involved on large

mine sites.

Create a more quantified shared language that is

machine friendly in terms of processing but honours intrinsic

geology.

Why Take a DNA Approach to Testing

How will large numbers of

small highly constrained

samples tell us anything about

the geometallurgical nature

of giant ore deposits and big

mines

Consider an analogy with

DNA sequencing the

precise nature

of constrained samples will

allow fundamental models to be

constructed that can define the

overall nature of the beast..
