Nifty mining and milling capacity (annualized based on Apr-Sep actuals) increased to
2.4mn tonne
Mt Gordon production ramp up accomplished successfully and reached pre-C&M level
Mt Gordon resources increased from 0.55mn MT of contained copper to 2.07mn MT of
contained copper
Improvement in Site Unit costs vs LY YTD
Working on various Cost optimization initiatives at both mines
Lower LME, higher exploration costs and heavy congestion at Port Hedland adversely
affected shipments and in turn resulted in lower profitability
Generated Operating EBITDA of $ 26.2mn, incurred $ 9.8mn on Exploration cost, so net
EBITDA was $ 16.4mn in H1 FY13

Nifty: Further Cost Optimization Initiatives
Mining:
• Reduce and/or optimise the cost of development- To optimize Fibrecrete, consumables and
support
• Reduce and/or optimise the cost of blasting- Optimize Powder factor, drill design, explosive pricing
• Maximise haulage capacity- To improve time management, designs
• Maximise effectiveness of pastefill- To have supplementary paste plants, rock fill
Processing:
• Change delivery system- Optimise cement addition by improving delivery system
• Look for methods of recovery improvements
Maintenance:
• Optimise Numbers- Review and rationalize personnel numbers in line with benchmark report
• Review cost through strategy rebuild plan- put in optimised rebuild strategy in place
Cost optimization initiatives targeted to achieve savings of more than $ 12mn
per annum compared to current costs
Cost optimization gain will start flowing from Q3, full gain likely
from next FY

associated with high grade sulphide
ore zones
The antiform is bounded NW- to
WNW-trending faults, the Haldi and
Masala faults, in the pit.
Reactivation along early normal
faults suggests they are early basin-

been reactivated during

2012 ANNUAL REPORT – MANAGEMENT DISCUSSION AND ANALYSIS
1. Recoverable copper in the inventory under leach is additional to measured mineral resources.
The information in this table which relates to Mineral Resources for the Nifty and Mt Gordon operations is a depletion of the 2012 Mineral Resource which is based on and accurately reflects reports prepared by Mr Geoff Bullen in 2010 and Mr. Peter Ball in 2012.The information in this report which Relates to Mineral Resources for the Maroochydore project is based on and accurately reflects reports prepared by Mr Geoff Bullen in 2010. Mr Bullen and Mr ball has the necessary experience relevant to the style of mineralisation, the type of deposit and the activity undertaken to qualify as a ‘Competent Person’ under the JORC Code for Reporting of Mineral Resources and Ore Reserves (2004 Edition). Mr Bullen and Mr Ball have given his consent to the inclusion of the material in the form and context in which it appears. Mr Bullen was an employee of Aditya Birla Minerals Limited during the period of the 2010 reporting. Mr. Ball of DataGeo Geological Consultant (an independent geological consultant).
Aditya Birla has had preliminary studies carried out for the Deposits currently reporting Mineral Resource at Mt Gordon to establish if it is economic to mine at a lower head grade and hence cut-off. This work has suggested that material within the mineral resource above a cut-off of 0.5% has the potential to be mined by bulk underground methods.
The Measured and Indicated Minerals Resource tabled above are inclusive of those Mineral Resources modified to produce the Ore Reserve. In all Resources and Reserves tables, significant figures do not imply precision. Figures are rounded according to JORC Code guidelines.
The depletion of the Mineral Resources for the Nifty and Mt Gordon operations for the 2012 reporting is based on and accurately reflects reports prepared by Mr Peter Ball of DataGeo Geological Consultants (an independent geological consultant) in 2012. Mr Ball is a member of the AusIMM(CP-Geo) and Mr Sivasamy is a Mebber of the Australian Institute of Mining and metallurgy. Mr Ball has the qualifications and necessary experience with this style of mineralisation to qualify as a competent person as described by the 2004 JORC Code for reporting of Mineral Resources and Ore Reserves. Mr Ball and Mr Sivasamy has given their consent to the inclusion of the material in the form and context in which it appears. Mr Sean Sivasamy is an employee of Aditya Birla Minerals limited.
