Synopsis: In a development that strengthens the company’s raw material security, J. K. Cement Limited has been declared the Preferred Bidder for the Karunda Limestone Block-I in Chittorgarh, Rajasthan, following an e-auction conducted by the Government of Rajasthan.
A limestone block win in Rajasthan’s Chittorgarh district brought J. K. Cement Limited back into the regulatory spotlight on Wednesday, after the company filed a disclosure dated April 23, 2026. The filing confirmed that the Government of Rajasthan declared JK Cement the Preferred Bidder in the e-auction for Karunda Limestone Block-I , a mining lease covering 35.98 hectares
With a market capitalisation of Rs. 44,776.95 crore, the shares of J. K. Cement Limited was trading at Rs. 5,794 per share, down 3.05 percent from its previous close of Rs.5,977. It is trading at a P/E of 40.6 apiece.
The Karunda Limestone Block-I is situated in Chittorgarh, Rajasthan ; a district that sits within one of India’s most limestone-rich belts and in close proximity to JK Cement’s existing North India manufacturing infrastructure. The block was put up for competitive e-auction by the state government, and JK Cement’s selection as Preferred Bidder is the first step in the formal grant of a mining lease; execution of the lease deed and regulatory clearances will follow before extraction can commence.
Limestone is the primary raw material in cement production, typically constituting around 1.5 tonnes of input per tonne of clinker produced. Captive limestone blocks reduce dependence on merchant limestone purchases, which are subject to price volatility and supply disruptions.
For a company with JK Cement’s scale in North and Central India, each additional block secured through competitive auction extends the raw material runway and moderates long-run production costs. At 35.98 hectares, Karunda Block-I is not a large reserve, but its strategic value lies in geographic proximity to existing plants rather than sheer reserve size.
The filing notes that standard SEBI disclosure requirements under the Master Circular are not applicable to this event type, which means the company is not obligated to disclose reserve estimates, expected annual extraction volumes, or capital expenditure plans at this stage. Those details typically emerge at the mining plan approval stage.
