Star Cement Declared Preferred Bidder for Assam Limestone Block; Shares Edge Higher

Mumbai, June 24: Star Cement Ltd has emerged as the preferred bidder for the Boro Lakhindong (West Block) limestone mining lease in Assam, marking a potentially important step in strengthening its long-term access to a key raw material used in cement manufacturing.

The company disclosed in an exchange filing that it was declared the preferred bidder following an e-auction conducted by the Government of Assam. The limestone block is located in Boro Lakhindong village in Dima Hasao district, formerly known as North Cachar Hills.

According to the filing, the mining lease area spans about 123 hectares and carries estimated limestone resources of 207.822 million tonnes. The preferred bidder status follows the auction process and represents a significant milestone before the grant of the mining lease, subject to applicable procedures and approvals.

For a cement manufacturer, access to limestone reserves is strategically important as it helps secure raw material availability, supports capacity planning and reduces dependence on external sourcing over the long term.

Stock Market Snapshot

Investors reacted positively to the development as the market assessed the potential long-term benefits of securing additional mineral resources.

As of 11:42 IST on June 24, 2026, Star Cement shares were trading at ₹211.70, up ₹1.33 or 0.63% for the session. The Star Cement share price remained in focus after the company announced its success in the Assam mining auction.

While the immediate financial impact of the preferred bidder status may not be visible, market participants often view resource security favourably because it strengthens operational visibility and supports future expansion plans.

Why The Limestone Block Matters

Limestone is the primary raw material used in cement production, making access to quality reserves a critical factor for industry players. Companies with captive limestone resources generally enjoy better control over supply chains and production economics.

The newly awarded block’s estimated resource base of more than 207 million tonnes could provide substantial long-term support to Star Cement’s manufacturing requirements, subject to successful completion of the mining lease process and eventual development of the asset.

The development also aligns with the industry’s broader focus on securing mineral reserves to support future capacity additions and regional demand growth.

Conclusion
