#GSSADD17

Facilitate, promote & encourage exploration discovery

OR

Reduce Exploration Risk

How . . .

• Provision of high quality geoscience data & knowledge• Open file data, precompetitive data, research collaboration

• Targeted initiatives• PACE programs, Coompana, NDI

• Aligned under key UNCOVER themes

GSSA Role – Commodities & Discovery

#GSSADD17

But which commodities ?

• Resources Inventory well defined • Incremental exploration opportunities• Development/production constrained

by commercial considerations

• Natural geological endowment in SA• Long term market position

DISCOVERY CONSTRAINED

• Recognised potential in SA• So far lacking exploration success or scale

significanceCONCEPT DEVELOPMENT STAGE

DEVELOPMENT

EXPLORATION

PROJECT GENERATION

#GSSADD17

Commodity context to Geoscience programs• Ensuring outcomes can be translated to practical exploration outcomes

Adopting a Mineral Systems Approach• Prediction vs Detection

Aligned with UNCOVER themes

GSSA Approach

#GSSADD17

What?• ‘all geological factors that

control the generation and preservation of mineral deposits’ (Wyborn et al, 1994)

Mineral Systems – the “What”

(Joly, 1993)

#GSSADD17

UNCOVER – PREDICTION - DETECTION – the “How”

#GSSADD17

Gold• 115Moz total inventory

• 109Moz Cu-Au, 6Moz Au-only

• 4.9Moz production to date

• 110Moz resource/16Moz reserve

So where to from here . . . .
