Newcrest December 2013 Resources and Reserves Statement

(all figures in United States dollars and in 100% terms unless stated otherwise)
MELBOURNE, Australia, Feb. 14, 2014 /CNW/ - Newcrest Mining Ltd. (Newcrest) has updated its Mineral Resource and Ore Reserve estimates for the 12 month period ending 31 December 2013, and these are presented in Tables 1 to 4 below.
The reserves estimates reported in this release have been prepared under the direction of a Qualified Person, as defined in NI 43-101, using accepted industry practice and have been classified in accordance with the JORC Code1. Except as described below, there are no material differences between the definitions of Proven and Probable Mineral Reserves under the applicable definitions adopted by the Canadian Institute of Mining, Metallurgy and Petroleum (the "CIM Definition Standards") and the corresponding equivalent definitions in the JORC Code for Proved and Probable Ore Reserves.
It is noted that under the CIM Definition Standards, the completion of a pre-feasibility study is the minimum prerequisite for the conversion of Mineral Resources to Mineral Reserves. The CIM Definition Standards define a pre-feasibility study as "a comprehensive study of a range of options for the technical and economic viability of a mineral project that has advanced to a stage where a preferred mining method, in the case of underground mining, or the pit configuration, in the case of an open pit, has been established and an effective method of mineral processing is determined. It includes a financial analysis based on reasonable assumptions on mining, processing, metallurgical, economic, marketing, legal, environmental, social and governmental considerations and the evaluation of any other relevant factors which are sufficient for a Qualified Person, acting reasonably, to determine if all or part of the Mineral Resource may be classified as a Mineral Reserve".
The JORC Code 2012, which came into effect on 1 December 2013, prescribes completion of a pre-feasibility study as a minimum prerequisite to declare an Ore Reserve (the JORC equivalent of a Mineral Reserve); however this requirement of the JORC Code does not come into effect until 1 December 2014.
A pre-feasibility study within the meaning of the CIM Definition Standards has not yet been completed in respect of Newcrest's Ridgeway Deeps Lift 2, Telfer Underground (VSC), O'Callaghans and Hiré deposits. Accordingly, the tables below present Newcrest's total Ore Reserves, as classified in accordance with the JORC Code, and include a reconciliation to identify:
(a) the Ore Reserves that could be classified as Mineral Reserves under applicable CIM Definition Standards; and
(b) the Ore Reserves which would not be classified as Mineral Reserves under applicable CIM Definition Standards, as required by NI 43-101. It is planned to complete the required studies to support Mineral Reserves estimation for those deposits during 2014.
The Mineral Resources estimates have been prepared under the direction of a Qualified Person, as defined in NI 43-101, using accepted industry practice and have been classified and reported in accordance with the JORC Code. There are no material differences between the definitions of Measured, Indicated and Inferred Mineral Resources under the CIM Definition Standards and the equivalent definitions in the JORC Code.
_______________________________
1 Newcrest reports its resource and reserve estimates in compliance with the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the JORC Code).
Mineral Resources are quoted inclusive of Ore Reserves.
Long term metal price and foreign exchange assumptions for Mineral Resources and Ore Reserves are set out in the table below. They are unchanged for both Newcrest and the Morobe Mining Joint Ventures (MMJV) managed sites from those adopted for the 31 December 2012 estimates, other than for Gosowong for which Newcrest has now adopted the same assumptions. Where appropriate, Mineral Resources are also spatially constrained within notional mining volumes based on metal prices of US$1,400/oz for gold and US$4.00/lb for copper. This is a conservative approach adopted to eliminate non-contiguous mineralisation from resource estimates.
Long Term Metal Price Assumptions | Newcrest Managed | MMJV Managed |
Mineral Resource Estimates | ||
Gold - USD/oz | 1,350.00 | 1,400.00 |
Copper - USD/lb | 3.10 | 3.50 |
Silver - USD/oz | 23.00 | 25.00 |
Ore Reserve Estimates | ||
Gold - USD/oz | 1,250.00 | 1,250.00 |
Copper - USD/lb | 2.70 | 3.10 |
Silver - USD/oz | 20.00 | 21.00 |
Long Term Exchange Rate USD: AUD | 0.80 | 0.90 |
As is typical with epithermal deposits, the deposits at Gosowong and Hidden Valley contain amounts of silver. The Cadia East porphyry deposit contains some molybdenum in addition to the gold, copper and silver reported.
In this section, the term "Cadia Province" refers to Cadia Hill, Ridgeway, Ridgeway Deeps, Big Cadia, Cadia Extended and Cadia East. The term "Telfer Province" refers to the Main Dome open pit, the West Dome open pit, Telfer Underground, Telfer Satellite Deposits and O'Callaghans.
Colin Moorhead (BSc (Hons), FAusIMM), a Competent Person (as defined in the JORC Code) and a Qualified Person (as defined in NI 43-101), has approved the data set out below, including sampling, analytical and test data underlying the results. For a description of the quality assurance program and quality control measures applied, please refer to the applicable technical report filed at www.sedar.com. Newcrest has also lodged Explanatory Notes for the Annual Mineral Resources & Ore Reserves Statement - 31 December 2013 on its website at www.newcrest.com.au. These notes provide additional information in support of the 2013 Resources and Reserves Statement.
The Morobe Mining Joint Ventures' Mineral Resources and Ore Reserves are quoted at Newcrest's 50% interest.

Table 4: Mineral Resources Statement as at December 31, 2013
Table 4 sets out estimates of Measured, Indicated and Inferred Mineral Resources for Newcrest's assets as at December 31, 2013. Mineral Resources are reported inclusive of Ore Reserves. As a result, Ore Reserve estimates should not be added to the corresponding Mineral Resource estimates.
Mineral Resources that do not form part of the Ore Reserves do not have economic viability. Due to lower certainty of their recoverability, the inclusion of resource estimates should not be regarded as a representation by Newcrest that such amounts can necessarily be economically exploited, and investors are cautioned not to place undue reliance upon such figures. Therefore, no assurances can be given that the estimates of reserves or resources presented in this release will be recovered at the tonnages and ore grades presented, or at all.
