Vedanta Aluminium Metal Ltd has taken a significant step towards securing its raw material supply by obtaining the long-awaited consent to operate its Sijimali bauxite mine in Odisha. This development comes at a critical time as the company faces a pricing dispute with its long-term supplier, Odisha Mining Corporation Ltd (OMCL). The company aims to commence production this financial year, targeting an initial output of 1 million tonnes, which is expected to ramp up to 5-6 million tonnes by FY28.
Sijimali Mine: A Strategic Move for Vedanta
The Sijimali bauxite mine, which received its operational consent in September 2026, is poised to play a crucial role in Vedanta's supply chain. Currently, Vedanta requires approximately 12 million tonnes of bauxite annually to sustain its 3 million tonnes of aluminium production capacity. Historically, the company has relied heavily on bauxite sourced from OMCL and imports, which has made its cost structure vulnerable to fluctuations in global bauxite prices.
The CFO of Vedanta, Anup Agarwal, highlighted during the company's September-quarter earnings call that the Sijimali mine is expected to replace imported bauxite, leading to savings of around $25 per tonne. This is particularly significant as Vedanta anticipates facing a price increase of $8-10 per tonne from OMCL due to the ongoing dispute over pricing adjustments.
Pricing Dispute with Odisha Mining Corporation
Vedanta's relationship with OMCL has been strained due to a long-standing dispute regarding the pricing of bauxite. The company is currently contesting OMCL's revised pricing structure in the [Supreme Court](/topic/supreme-court-of-india), with the case partially heard and set for further proceedings after the Diwali break. Should the court rule against Vedanta, the company could be liable for ₹5,600 crore in past dues and face higher future procurement costs.
Despite the legal challenges, Vedanta continues to procure bauxite from OMCL under protest, adhering to the prices set by the state-owned miner. Agarwal noted that Vedanta plans to increase its sourcing from OMCL from the current 2.4 million tonnes per year to as much as 4.8 million tonnes, as OMCL ramps up its production capacity. This increase is in line with OMCL's long-term linkage policy, which reserves 80% of the expanded output for Odisha-based refineries.
Cost Implications and Future Projections
Analysts suggest that Vedanta's strategy to increase domestic bauxite sourcing through the Sijimali mine and higher procurement from OMCL will ultimately lead to overall cost savings. Shweta Dikshit, lead metals and mining analyst at Systematix Group, stated that while Vedanta may incur higher costs from OMCL as sourcing volumes increase, the cost of OMCL bauxite remains more competitive than imported alternatives.
The company is targeting a significant reduction in its hot metal production costs, aiming to lower it to around $1,550 per tonne from the current range of $1,710-1,720 per tonne in the first half of FY27. This ambitious goal is supported by the expectation that increased captive alumina production and domestic bauxite sourcing could yield savings of $100-125 per tonne.
Expansion Plans and Community Engagement
In addition to the Sijimali mine, Vedanta has secured the Karlapat bauxite block in Odisha, with its subsidiary Bharat Aluminium Co. (Balco) being declared the preferred bidder. Balco's bid included a remarkable 175% auction premium, marking it as the highest premium offered for a bauxite block auction in India. This acquisition is part of Vedanta's broader strategy to secure raw materials for its planned expansion of aluminium smelting and alumina refining capacities.
The company aims to increase its captive bauxite contribution from approximately 40% currently to 75% by the end of FY27, facilitated by the ramp-up of its mines and expanded supply from OMCL. However, the operationalization of the Sijimali mine hinges not only on regulatory clearances but also on securing the cooperation of local communities, which is essential for sustainable mining operations.
Conclusion: A New Chapter for Vedanta
As Vedanta embarks on this new chapter with the Sijimali bauxite mine, the company is strategically positioning itself to mitigate risks associated with pricing disputes and supply chain vulnerabilities. The anticipated increase in domestic bauxite sourcing, coupled with the ongoing legal battle with OMCL, will be pivotal in shaping Vedanta's operational landscape in the coming years. The company's ability to navigate these challenges will ultimately determine its competitiveness in the aluminium market and its long-term sustainability in the industry.
