Is Iron Still Worth It ?
In the News :
China slow down :
==> picture [386 x 315] intentionally omitted <==
The Chinese economy was expected to grow 7.8 per cent in 2012 and 8.2 per cent in 2013, the IMF said. Oct 9[th] AAP
This is a very good slow down ! Will still require Iron
Slide 6
Is Iron Still Worth It ?
In the News :
Iron price reduction
Hematite producers reducing project expenditure

Slide 7
Is Iron Still Worth It ?
Implications – all in U$ :
Est’ Marginal Chinese Costs – Westpac CAP Est’ (@ 69% Fe)
• Probable Future Base cost for 62% $120/t • CAP will realise a premium (69% Fe) • Hawsons very profitable at $120/t (62% Fe)

Slide 8
HAWSONS IRON PROJECT Largest Magnetite Project in NSW
- Resource – very large with potential for
50 year plus mine life
Native Title has been extinguished
==> picture [389 x 234] intentionally omitted <==
-
Mining – very low unit costs because low strip ratio, very wide mining widths, low abrasion index and single pit
-
Processing - comparatively very low cost because of very soft mineralised rock
-
Infrastructure – water, power, transport
-
and port all available for start up
-
Approvals – low hurdles compared

HAWSONS IRON PROJECT Maiden Resource / Exploration Target[1 ]
JORC Inferred Resource (12% DTR cut off)
1.4 billion tonnes at 15.5% mass rec. 220 million tonnes of concentrate 69.9% Fe; 2.50% SiO2; 0.22% Al2O3; 0.002 P2O5
Exploration Target[1] 6 to 11 billion tonnes
==> picture [267 x 168] intentionally omitted <==
900-1,900 million tonnes of concentrate DTR 14-17%, Con’ Grade 69 – 71% Fe
1 The potential quantity and grade of the exploration targets is conceptual in nature and there has been insufficient exploration to define a Mineral Resource. It is uncertain if further exploration will result in the determination of a Mineral Resource. (DTR is Davis Tube Recovery)
Eastern limit of Inferred Resource
10
Hawsons EXPLORATION PORTFOLIO At 15.5% DTR - Why Does it Work ?
The Value at Hawsons :
1. Low waste to Ore ratio (0.3:1)
- Mining costs low - not mining too much waste
2. Large mining widths and single pit to year 20
-
Mining costs low – thick consistent Fe units
-
Large and easy to move material – in pit crushing and conveyancing
-
Minimising truck usage – lower OPEX
3. Soft Ore
-
Lower mining costs (compared to BIF’s)
-
Lower grinding (processing costs)
-
Reduce CAPEX
4. High grade concentrate will low contaminants
5. Infrastructure
-
Power, water, rail, mining community
-
Port availability

HAWSONS IRON PROJECT
Why Does it Work ? – Soft Ore
Unique Metallurgical Characteristics :
- Low bond work index of 6 - 8 kWh/t
(BIF’s ~ 15 – 30 kWh/t)
- Low abrasion index ~ 0.09
(BIF’s ~0.3 – 0.7 )
-
Rock Strength (UCS) 50 – 90 Mpa
-
(BIF’s ~ 355 Mpa )
All this shows very soft ore

Tungsten Production
-
Historically China controls supply
-
China dominated in ‘80 & ’90’s
-
Chinese mines historically high graded
-
ATP plants installed were artificially supported by government
-
Created artificial supply cheap W
-
Results today
-
West stopped W exploration
-
Chinese mines now operate at higher costs
-
China now a net importer of W
-
China imposes a 5% tariff on all W exports
-
Identified globally as a Strategic Material

Tungsten – What you may not know
-
Tungsten Properties
-
Highest melting point of ALL metals
-
Hard metal therefore robust
-
SG 19.3 – very dense
-
Thermal Expansion 40% of steel
-
Uses for Tungsten include: -
-
Hard wearing tool protection (Tungsten Carbide / Tool Steel)
-
Mining drill bits
-
Machine tools / cutters
-
-
Heat sinks / Transition spacers
-
Furnace and Light bulb elements

The information in this presentation that relates to Exploration Results and Resources is based on information compiled by S.N.Sheard, who is a Fellow of the Australian Institute of Geoscientists and has had sufficient experience which is relevant to the style of mineralization 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 of Exploration Results, Mineral Resources and Ore Reserves'. S.N.Sheard is an employee of Carpentaria and consents to the inclusion in the report of the matters based on his information in the form and context in which it appears.
