Highly placed sources in mining outfit informed that GMDC has allocated close to 10 million tonnes of limestone reserves for four cement manufacturing projects. "We had received expressions of interest (EoIs) from six or seven cement players. Of them we have short-listed around four companies and have also identified limestone from our own reserves. We are now waiting for government approval to enter into longterm supply agreements with these companies," said a GMDC official. At least three of these companies are major players like ACC, Reliance Cementation and Adani Enterprises. GMDC has allocated 2.5 million tonnes of limestone reserves for each at Kutch.
