Important information 

The information in this presentation is designed as an aid to a spoken 

explanation. It is not to be considered without that explanation. It is not 

intended to guide any investment decisions in Terramin Australia Ltd. 

The information is intended as a guide to the potential of Terramin’s 

projects but is not predictive. Consideration of the technical and financial 

factors requires skilled analysis and understanding of the context. 

The information in this report that relates to Exploration Results and Mineral Resources is based on information compiled by Mr. Robert Singer. Mr 

Singer is a Member of The Australasian Institute of Mining and Metallurgy. Mr Singer is Chief Geologist and a full time employee of Terramin 

Australia Limited. He has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the 

activity which he is undertaking to qualify as a Competent Person as defined in the 2004 Edition of the ‘Australasian Code for Reporting Exploration 

Results, Mineral Resources or Ore Reserves’. Mr. Singer consents to the inclusion in the report of the matters based on his information in the form 

and context in which it appears.

Outline of talk 

Introduction 

Update on Angas Mine 

What have we learnt 

What do we do next 

Terramin’s other assets 


Angas Mine 

60 km from Adelaide 

Australia’s first mining 

belt (c1845) 

Company tenements 

total 1,160km 2 

Angas: new discovery 1991 

• Mining Lease grant August 2006 

• MARP approved March 2007 

• Construction from June 2007 

• Milling from August 2008 

Fast (but not always 

smooth) path to production 



Angas – low operating cost attributes 

shallow virgin ore body 

coarse grind 

precious metals credit 

grid power- low fixed price 

no fly-in fly-out 

local equipment support 

services 


Angas Mine– Progress to date 

Decline at -250m 

• Over halfway 

there 

Development on 

nine levels 

+700,000t mined 

Good 

reconciliation- 

• but not always 


Angas Mine- 2010 A Year of Change 

 

 

Change in key management personnel 

• New General Manager- Rob Howie 

• New Metallurgy Superintendent- Rene van Oevelan 

• New Mine Manager- Andrew Harris 

Change in operating environment 

• Enterprise agreement negotiations 

• Work roster changes 

• Staff turnover 

• More diverse workforce 

• A real mine 



Now we are at steady state- where to next 

Refocus on exploration 

Mapping and structural modelling at Angas 

Developing new exploration model 

Drill more holes! Where 



-Near Mine potential 


Angas Mapping

Angas Mine and beyond 

Angas is not the only target 

Northern Fleurieu/ Adelaide hills area 

Menninnie Dam- Eyre Peninsula 

Tala Hamza- Algeria 


Terramin – SA Exploration 


VTEM & Magnetic Survey 

Objectives: 

 

 

 

 

EM detection of base metal 

sulphide deposits in Kanmantoo 

basement rocks beneath 

electrically conductive cover 

(Murray Basin and younger). 

Improved understanding of the 

structural characteristics of the 

basement rock packages 

Identification and mapping of fluid 

pathways and alteration systems 

Extensions and additions to 

Angas mine resource 

Processing, interpretation and 

target generation is in progress. 

Area flown by VTEM helicopter survey

KC2 

Menninnie – ready to move 

 

 

 

 

 

 

Open Central Zone Inferred Resource of 

3.8Mt @ 4.0% Zn and 3.2% Pb, and 

34g/t Ag 

160km from Pt Pirie lead smelter 

High lead content 

Other prospects with good Pb-Zn drill 

results 

Large geophysical and Cu-Pb-Zn 

geochemical anomalies 

Concept a central plant with satellite 

orebodies 

Drilling possible from early 2011 


Slide 20 

KC2 Ken Cross, 25/11/2010

Menninnie – ready to move 

 

 

 

 

 

 

 

 

Terramin to regain exploration management 

Open Central Zone Inferred Resource of 

3.8Mt @ 4.0% Zn, 3.2% Pb, 34g/t Ag 

160km from Pt Pirie lead smelter 

Other prospects with good Pb-Zn drill results 

Large geophysical and Cu-Pb-Zn geochemical 

anomalies to be drilled in 2011 

Indications of more widespread mineralisation 

within and beneath Gawler Range Volcanics 

Encouraging discoveries of epithermal vein 

systems that may host Au and Ag-Pb-Zn 

Concept a central plant with satellite orebodies 


Menninnie 


The Tala Hamza deposit 

Mineral Resource 

Measured, Indicated 

and Inferred 

68.6 Mt at 4.6% Zn, 

1.1% Pb 

As at November 2009 

Resource inclusive of Reserve 

Ore Reserve 

Probable 

38.1Mt @ 4.8% Zn, 

1.4% Pb 

As at August 2010 

Note: See slides 35 and 36 for complete 

JORC Statement 


Conclusion 

Terramin is poised for a period of growth: 

 

Completion of the Tala Hamza DFS is a milestone toward a major mine 

that’s set to commission as other major Pb-Zn mines close 

 

Angas is running smoothly and will be a major cash flow generator in 

2012-15, and beyond. 

 

Fleurieu exploration is rejuvenated with several new targets in the pipeline 

 

Gawler Ranges projects provide high expectation for substantial additions 

to known Pb-Zn resources and new Cu and/or Au discoveries
