l Certain oral and written statements contained or incorporated by reference in this presentation, including information as to the future financial or operating performance of the Company and its projects, constitute forward-looking statements. All statements, other than statements of historical fact, are forward-looking statements. The words “believe”, “expect”, “anticipate”, “contemplate”, “target”, “plan”, “intend”, “continue”, “budget”, “estimate”, “may”, “will”, “schedule” and similar expressions identify forward-looking statements.
Forward-looking statements include, among other things, statements regarding targets, estimates and assumptions in respect of nickel, gold or other metal production and prices, operating costs and results, capital expenditures, mineral reserves and mineral resources and anticipated grades and recovery rates. Forward-looking statements are necessarily based upon a number of estimates and assumptions related to future business, economic, market, political, social and other conditions that, while considered reasonable by the Company, are inherently subject to significant uncertainties and contingencies. Many known and unknown factors could cause actual events or results to differ materially from estimated or anticipated events or results reflected in such forward-looking statements. Such factors include, but are not limited to: competition; mineral prices; ability to meet additional funding requirements; exploration, development and operating risks; uninsurable risks; uncertainties inherent in ore reserve and resource estimates; dependence on third party smelting facilities; environmental regulation and liability; currency risks; effects of inflation on results of operations; factors relating to title to properties; native title and aboriginal heritage issues; dependence on key personnel; and share price volatility and also include unanticipated and unusual events, many of which are beyond the Company’s ability to control or predict.
The Company disclaims any intent or obligation to update any forward-looking statements, whether as a result of new information, future events or results or otherwise. All forward-looking statements made in this presentation are qualified by the foregoing cautionary statements. Investors are cautioned that forward-looking statements are not guarantees of future performance and, accordingly, not to put undue reliance on such statements.

Notes:
- For the Open Pit Mineral Resource estimate, mineralisation in the Havana, Havana South, Tropicana and Boston Shaker areas was calculated within a US$1,550/oz pit optimisation at an AUD:USD exchange rate of 1.03 (A$1,500/oz).
Notes:
-
The Proved and Probable Ore Reserve (December 2012) is reported above economic break-even gold cut-off grades of 0.4 g/t for Transported/Upper Saprolite material, 0.5 g/t for Lower Saprolite material, 0.6g/t for Sap-Rock (Transitional) material and 0.7g/t for Fresh material at nominated gold price US$1,300/oz, oil price US$86/barrel and exchange rate 1.02 AUD:USD (equivalent to A$1,278/oz Au).
-
The Open Pit Mineral Resources have been estimated using the geostatistical technique of Uniform Conditioning, using cut-off grades of 0.3g/t Au for Transported and Saprolite material, 0.4g/t Au for Transitional and Fresh material.
-
The Havana Deeps Mineral Resource estimate has been reported outside the US$1,550/oz pit optimisation at a cut-off grade of 1.73g/t Au, which was calculated using a gold price of US$2,000/oz (AUD:USD 1.05) (A$1,896/oz).
-
The Competent Persons statement is incorporated in the JORC Code and Forward-Looking Statements section of this report.
Reference : ASX Release dated 25 October 2013 Mineral Resources and Ore Reserves Estimates at 30 June 2013
-
The Havana Deeps Underground Mineral Resource was estimated using the geostatistical technique of Ordinary Kriging using average drill hole intercepts.
-
Resources are inclusive of Reserves.
-
JV partner and TGP Manager AngloGold Ashanti Limited reports Mineral Resources and Ore Reserves by calendar year. An updated Mineral Resource estimate is expected at the end of calendar 2013.

Notes:
-
Teutonic Bore Mineral Resource estimate is as at August 2009 and was previously reported in accordance with the 2004 Edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’. It has not been updated since to comply with the JORC Code 2012 on the basis that the information has not materially changed since it was last reported.
-
All Measured Resource and associated dilution was classified as Proved Reserve. All Indicated Resource and associated dilution was classified as Probable Reserve.
-
Mining depletion as at 30 June 2013 has been removed from the 2013 reserve estimate.
-
Mineral Resources include massive sulphide and stringer sulphide mineralisation. Massive sulphide resources are geologically defined, stringer sulphide resources are reported above cut-off grades of 0.5% Cu for Bentley and Jaguar, 0.7% Cu for Teutonic Bore.
-
The Bentley underground reserves have decreased by 1.1 million ore tonnes as a result of depletion 313,000 ore tonnes, changes in realised (AUD) metal prices within the net smelter return cut off valuation process and increases in the site cut-off values ( 2013 $180/t direct feed and $120/t marginal feed versus 2012 $160/t direct feed and $100/t marginal feed ) have impacted mainly in the Arnage stringer material resulting in a reduction of 590,000 ore tonnes, changes in resource interpretation along boundaries on ore surfaces, and minor changes in mining method in the Brooklands surface of 16,000 ore tonnes.
-
Block modelling used ordinary kriging grade interpolation methods within wireframes for all elements and density.

Notes:
-
All Resources tonnes have been rounded to the nearest one thousand tonnes and grade to the nearest 1/10th percentage/gram per tonne.
-
Mineral Resources include massive sulphide and stringer sulphide mineralisation. Massive sulphide resources are geologically defined, stringer sulphide resources are reported above cut-off grades of 0.5% Cu.
-
Au grades for Wilga are all inferred due to paucity of Au data in historic drilling.
-
Block modelling used ordinary kriging grade interpolation methods within wireframes for all elements and density.
-
Mining depletion as at end of historic mine life (1996) has been removed from the Resource estimate for Wilga.
Notes:
-
All Reserves tonnes have been rounded to the nearest one hundred thousand tonnes and grade to the nearest 1/10th percentage/gram per tonne.
-
No Ore Reserves were reported in 2012.
-
Gold (Au) grades are Inferred at Wilga due to a paucity of gold assays in historic drilling. Revenue from gold in the Wilga ore was included in the estimation of the Ore Reserve. The contribution to Revenue of this gold was estimated to be $3.84 per gram of gold in situ . This inclusion was not material to the value of the mining envelopes considered and did not warrant downgrading of any portion of the Ore Reserve attributable to Wilga. The contribution from Wilga represents 13% of the Total Ore Reserve.
-
Historic mining depletion for Wilga has been removed from the 2013 reserve estimate.

Notes:
-
The Mineral Resource estimate was estimated within a conceptual A$1,600/oz Au pit optimisation completed in 2012 and for the area of drill coverage at 100m x 50m spacing or less. Contained gold (oz) figures have been rounded to the nearest one hundred ounces.
-
Mostly RC drilling with 1m cone split samples analysed for Au by 50g fire assay.
-
Mineralisation was wireframed at a cut-off grade of 0.3g/t Au and Mineral Resources were reported above a cut-off grade of 0.5g/t Au.
-
The 2013 Mineral Resource estimate has reduced slightly from the 2012 estimate due to the closer spaced drilling in certain areas allowing refinement of the wireframes and grade interpolation search distances.
-
Block modelling used ordinary kriging grade interpolation methods for composites that were top-cut to 10g/t Au in the supergene zone and 16g/t Au for the remaining mineralisation. Top-cuts are not severe, trimming no greater than 0.5% of the samples.
-
There are no Ore Reserves for Karlawinda.
