  • 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 Geology and Resources

Five magnetic anomalies as target

  • Very limited outcrop

  • 20,000m drilling

  • 70 holes

Results

  • Consistent magnetite siltstone in all anomalies Exploration Target[1] 6 to 11 billion tonnes

  • 900-1,900 million tonnes of concentrate

  • Mass Recovery (DTR) 14-17% Concentrate Grade of 69-71% Fe

And a Maiden Resource

==> picture [381 x 320] intentionally omitted <==

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) 9

HAWSONS IRON PROJECT

Lower Mining Costs – In Pit Crushing and Conveying

  • Existing and Proposed IPCC operations e.g. :Bingham Canyon

  • – ~165Mtpa linked to the Copperton Concentrator by an 8km conveyor system

  • Escondida – Over 320Mtpa

==> picture [223 x 171] intentionally omitted <==

  • Benefits :Lower fuel usage (fuel and transport ~50% of mining costs )

  • Truck utilisation increase by up to 15%

  • less long up hill hauls

  • Uses Electrical power – lower cost

  • Better operational safety

  • Deeper mine – maximise resource

Transport Options – Great Optionality

Recent Developments – March 21, 2012

  • MOU signed with Flinders Ports to determine long term handling, storage and loading solution at Port Pirie, South Australia

Common User Facility for potential to export 20 – 30Mtpa of iron concentrates

Start Up Preference

  • Year 1 – 5MT

  • slurry to Broken Hill , rail to Port Pirie

  • Ramp up to yr 4 - 20MT

  • slurry to Broken Hill , slurry / rail to Port Pirie

  • 13Mtpa available using existing rail to Port Pirie

  • Port Capacity available at Port Pirie pending upgrade
