JSW Cement Ltd announced that it has been declared the preferred bidder for the mining lease of the Sikilangso Limestone Block in Assam. The company shared the update in a regulatory filing dated 2 March 2026.
The bid relates to an e-auction conducted by the Government of Assam for the allocation of limestone resources. JSW Cement participated in the auction and was identified as the preferred bidder for the block covering both Part A and Part B.
The disclosure was made to stock exchanges in line with the listing regulations applicable to the company.
The Sikilangso limestone deposit is located in Umrangso in the Dima Hasao district of Assam. The area forms part of a region where limestone deposits are present and are used in cement manufacturing.
The block is divided into 2 sections. Part A covers about 200 hectares, while Part B also covers roughly 200 hectares. The combined area of the 2 sections therefore totals about 400 hectares.
Limestone extracted from such blocks is typically used in the production of clinker, which is the key ingredient in cement.
State governments allocate mineral resources through an electronic auction process. Companies interested in mining rights place bids online during the auction.
After the bidding stage, the bidder offering the highest qualified bid is identified as the preferred bidder. This status indicates that the company has secured the top bid for the mineral block.
Further steps, including documentation and approvals from authorities, generally follow before the mining lease is formally granted.
JSW Cement operates as part of the JSW Group, which has businesses across steel, energy, infrastructure and cement. The group has an overall business footprint valued at about $23 billion.
The company said the information regarding the preferred bidder status has also been uploaded on its website.
