Highlights

Aditya Birla Minerals Limited (ASX - ABY) ("Aditya Birla" or "The Company") is pleased to announce an updated total in-situ Mineral Resource at the Company's Copper Operations of 79.73mt @ 1.28 % Cu for 1.02mt of contained copper.

• The "in-situ Sulphide" Mineral Resource for the Nifty Copper Operations as at 31/03/2016 totals 23.46Mt @ 2.03% Cu above a reporting cut-off grade 1.2% Cu.

• The "in-situ Oxide" Mineral Resource for the Nifty Copper project as at 31/03/2016 totals 4.33Mt @ 0.86% Cu above a reporting cut-off grade 0.4% Cu.

• The in-situ Mineral Resource for the Nifty Copper Project Heap Leach Pad ("Pad") as at 31/03/2016 totals 3.31Mt @ 0.74% Cu at a cut-off grade 0.5% Cu.

• The "in-situ Oxide and Supergene" Mineral Resource for the Maroochydore Copper project as at 31/03/2016 totals 43.20Mt @ 0.91% Cu and 391ppm Co above a reporting cut-off grade 0.5% Cu.

• The "in-situ Sulphide" Mineral Resource for the Maroochydore Copper project as at 31/03/2016 totals 5.43Mt @ 1.66% Cu and 292ppm Co above a reporting cut-off grade 1.1% Cu.

  Nifty Mineral Resource

  The in-situ Sulphide Mineral Resource total has been adjusted for model updates and mining during the period between 01/04/2015 - 31/03/2016.

  Changes to the in-situ Sulphide Mineral Resource since the last annual reporting for the Nifty Copper Operations include: -

• Updates to the Sulphide Mineral Resource model for Nifty to include additional geological information and ongoing re-interpretation.

• A revised estimation methodology.

• Changes to resource classifications to better reflect production results.

• Allowance for the full year production from the underground mine.

The Nifty Mineral Resource was updated using all appropriate information as at 31st March 2016 by Mr Sean Sivasamy (Sivasamy) of Aditya Birla Minerals Limited.

Production during the previous twelve months was depleted from the updated Sulphide Mineral Resource Model and the Nifty sulphide resource is now reported as 23.46Mt @ 2.03% at a cut- off grade of 1.2% Cu.

The Oxide and Supergene Resource for Nifty tonnes now reports at 4.33Mt @ 0.86% at a cut- off grade of 0.4% Cu, which also remained same as reported at 31st March 2015.

The Heap Leach Pad Mineral Resource for the Nifty Project remains same as estimated as at 31st March 2015 by DataGeo and totals to 3.31Mt at 0.74% Cu at a cut-off grade of 0.5% Cu.

The Mineral Resource has been classified and reported in accordance with the 2012 Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC, 2012).

The Nifty sulphide depletion work was carried out by Mr Sivasamy. The Nifty copper operation Mineral Resources are shown in Table 1.

Maroochydore Mineral Resource

The "in situ Oxide and Supergene" Mineral Resource for the Maroochydore Project as at 31st March 2016 remains same as estimated at 31st March 2013 by DataGeo. The Maroochydore Mineral Resource is 43.20 Mt @ 0.91% Cu and 391 ppm Co above 0.5% Cu cut-off grade.

The "In situ Sulphide" Mineral Resource for the Maroochydore copper project as at 31st March 2016 remains same as estimated at 31st March 2014 by Mr Sivasamy. The Sulphide Mineral Resource is 5.43Mt at 1.66% Cu and 292ppm Co above cut-off grade 1.1% Cu.

The Mineral Resource has been classified and reported in accordance with the 2012 Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC, 2012).

The Maroochydore Oxide and Sulphide Mineral Resources are shown in Table 2.
