Vedanta Resources plc

Production Release for the Fourth Quarter and

Full Year Ended 31 March 2013

Highlights

Ø Full year production growth across Oil & Gas, Copper, Aluminium, Lead and Silver

Ø Oil & Gas full year production 19% higher driven by 32% production growth at Rajasthan

Ø Commenced exploration drilling in Rajasthan and made a successful discovery; commenced oil production from Aishwariya and commercial gas sales from Rajasthan

Ø Record quarterly and full year production of mined zinc-lead and integrated silver at Zinc India

Zinc - India

Mined metal production was a record 260,000 tonnes in Q4, 16% higher than the corresponding prior period, and in line with the annual mine plan. Full year production was 870,000 tonnes, 5% higher than the previous year.

The integrated production of refined zinc was 181,000 tonnes in Q4, 8% higher than Q3. Full year production was 660,000 tonnes, in line with the annual plan. Sales of zinc metal-in-concentrate (MIC) were 61,000 tonnes, due to surplus concentrate in Q4. Integrated production of refined lead was 32,000 tonnes in Q4 and 107,000 tonnes for the full year, up 2% and 20% respectively.

Integrated production of silver was a record 3.22 million ounces in Q4 and 10.35 million ounces for the full year, up 20% and 36%, respectively, driven by the continued ramp-up of the SK mine and the Dariba lead smelter.

During the year, Rampura Agucha underground mine and Kayad mine achieved the milestone of development ore production as per plan.

Zinc International

Total production of refined zinc and mined zinc-lead MIC was 102,000 tonnes in Q4 and 426,000 tonnes for the full year, in line with the annual mine plan.

Oil and Gas

In Q4, average daily gross operated production was 202,014 barrels of oil equivalent (boe), 12% higher than the corresponding prior period. Working interest production was 18% higher at 126,623 barrels of oil equivalent per day (boepd). The increase was driven by ramp-up at the Rajasthan block, where gross production was 22% higher at 168,594 bopd in Q4.

At the end of Q4, oil production was commenced from Aishwariya, the third largest oil field in the Rajasthan block, which will ramp up to the FDP approved production level of 10,000 bopd. Commercial gas sales were also commenced from the Rajasthan block during Q4 with initial volumes of 5 million standard cubic feet per day.

Following clarification from the Government of India that exploration would be permitted in development areas, exploration drilling was commenced in the Rajasthan block in February. This is a step towards realising the basin potential of 300,000 bopd. Recent exploration drilling has resulted in a discovery, the 26th in the Rajasthan block.

In the Sri Lanka block, the Phase-II exploratory well encountered multiple reservoir sands without hydrocarbons, and was plugged and abandoned. Earlier, a three-well Phase-I exploration programme resulted in two successful discoveries. We continue to work on the Sri Lanka block, and the data from this Phase-II well along with the results of the prior two discoveries are being integrated to fully understand the future block potential.

Iron Ore

Iron ore operations continue to be affected by suspension of mining in Goa and Karnataka. At Karnataka, the matter for reopening of Category A and B mines has been heard by the Honourable Supreme Court, and the order has been reserved and is expected to be announced soon. Earlier a few Category A mines had been allowed to resume operations by the Court.

Regarding the suspension of mining in Goa, the Honourable Supreme Court is expected to fix the dates for initial hearings. In the meantime, the State Government and major miners including Sesa Goa, have filed their responses to the Central Empowered Committee report. Separately, we have filed an application to the Court seeking a stay on the suspension of mining and restrictions on ore transportation.

In Q4, production of pig iron and metallurgical coke were 75% and 48% higher at 104,000 tonnes and 94,000 tonnes, respectively, due to the new capacities commissioned in Q2 FY2013.

At our Liberia iron ore project, exploration activities are progressing well, and we remain on track to deliver the first shipment by end FY2014.

Copper - India and Australia

Copper cathode production was 86,000 tonnes in Q4, 7% higher than the corresponding prior period, and 8% higher at 353,000 tonnes in FY2013. Mined metal production at Australia was 28% higher at 7,000 tonnes in Q4 and 15% higher at 26,000 tonnes for the full year.

The first 80MW unit of the 160MW captive power plant at Tuticorin has been stabilised during the quarter and is now operating at capacity, with plant load factor (PLF) of 81% during the quarter. Surplus power generated by this plant beyond the captive consumption requirements were sold, and commercial power sales were 35 million units in Q4 and 42 million units for the full year. The second 80MW unit is expected to be synchronized in Q1 FY2014.

Tuticorin Copper Smelter Update

Following a few public complaints of emissions, we had responded to the queries of the Tamil Nadu Pollution Control Board (TNPCB) confirming that all plant parameters were within permitted limits. The District Administration confirmed that no case of illness was reported on account of the alleged emissions. However, TNPCB ordered closure of the smelter on 29 March 2013.

Separately, on 2 April 2013, the Honourable Supreme Court has upheld our appeal filed in 2010 against the Madras High Court order for smelter closure and ordered us to deposit INR 1 billion (approx. $18mn) with the District Collector, Tuticorin, which will be used to improve the environment, including soil and water, in the vicinity of the plant. Over the two year court process, regulatory bodies had inspected and confirmed that the plant meets the required standards. Some recommendations for improvements had been proposed by them, all of which had been implemented.

This Supreme Court order does not affect the recent closure order issued by TNPCB. We are actively engaged with TNPCB and relevant authorities to obtain permission to restart the operations. We have also filed an appeal with the National Green Tribunal against the closure order by TNPCB and for interim relief to operate the plant, and the matter is being heard.

 Copper - Zambia

Integrated production was 8% higher at 36,000 tonnes in Q4 and 16% higher at 160,000 tonnes for the full year, as compared with the corresponding prior periods. The increase was driven by production ramp-up at Konkola, due to development of dewatered reserves using the Konkola Deep Mining Project (KDMP) infrastructure, and by higher primary copper production at the Nchanga Tailings Leach Plant (TLP).

Total finished copper production was 15% higher at 54,000 tonnes in Q4, and 8% higher at 216,000 tonnes for the full year.

Mined metal production was 2% higher at 33,000 tonnes in Q4, and 12% higher for the full year. As compared with Q3, mined metal production was lower due to a temporary suspension of mining at the Chingola Open Pits (COP) F&D, due to non-renewal of mining contract.

At the KDMP, waste hoisting from the bottom-shaft loading level of the new shaft#4 is progressing as planned, and ore hoisting is expected to commence in Q2 FY2014.

Aluminium

Aluminium production was 10% higher at 195,000 tonnes in Q4, and 15% higher at 774,000 tonnes in full year, as compared with the corresponding prior periods. The Jharsuguda-I and Korba-II smelters operated above their rated capacities, with significant improvement in specific power consumption and throughput at Jharsuguda-I. Power sales at BALCO 270MW were lower in Q4 and full year due to evacuation constraints.

Alumina production at Lanjigarh remains temporarily suspended since 5 December 2012, due to inadequate availability of bauxite. We remain engaged with the Orissa state authorities for allocation of bauxite as per our existing MoU with the Orissa state government. Separately, we are working on obtaining bauxite supplies for the refinery from other sources including our captive mines at BALCO, in order to restart the refinery operations. As stated earlier, the production of alumina will not affect production at the smelters.

At the 325ktpa Korba-III aluminium smelter, mechanical and electrical completion and pre-commissioning of the rectifier, potline and related utilities for the first phase of 84 pots out of the total 336 pots have been completed. Further work is in progress, and we plan to tap first metal in Q2 FY2014. The smelter plans to initially draw power from the existing 810MW power plants at BALCO. The first 300MW unit of the BALCO 1,200MW captive power plant is awaiting final stage regulatory approvals.

Having obtained the Stage-II Forest Clearance for the 211mt coal block at BALCO, the process for diversion of forest land has been initiated by the State Government, and we are in the process of signing the mining lease agreement. We expect to commence mining in Q2 FY2014.

Power

Power sales were 22% higher at 2,356 million units in Q4 and 36% higher at 8,888 million units for the full year, as compared with the corresponding prior periods. The increase in Q4 was primarily due to higher power generation and sales from three units of the Jharsuguda 2,400MW power plant.

The plant load factor (PLF) of three operating units in Q4 was 58%, compared to 31% in Q3. Overall the station delivered an effective PLF of 44% considering all four units. The fourth unit was commissioned on 31 March 2013. The increase in PLF was driven by the commissioning of the new shared 1,000MW Raipur-Wardha transmission line in January 2013, and partial easing of the evacuation restrictions. We expect 50-60% PLF for all four units in the near future with further easing of evacuation restrictions.

Work at the Talwandi Sabo power project is progressing well and the first unit is expected to be synchronized in Q2 FY2014.

Refinancing of Put Option on US$883mn 4% Convertible Bonds due 2017

The total put option exercised on the US$883mn 4% convertible bonds due 2017 is $810 million, which is due for payment on 29 April 2013. Refinancing for this has been tied up through bank loans and existing cash.
