Sources in the investigating agency said that a chargesheet was likely to be filed on Monday before a designated court and the Supreme Court would be apprised of it.
The Supreme Court had asked the CBI, during the last hearing on February 11, to submit a status report on the filing of a chargesheet in six cases finalised by the agency.
The CBI has filed over 16 FIRs, including those against AMR Iron and Steel, JLD Yavatmal Energy, Vini Iron and Steel Udyog, JAS Infrastructure Capital, Grace Industries, Jindal Steel and Power, Rathi Steel and Power, Jharkhand Ispat, Green Infrastructure, Kamal Sponge, Pushp Steel, Hindalco, BLA Industries, Castron Technologies and Castron Mining and Nav Bharat Power.
These FIRs were registered after the agency probed three preliminary enquiries related to coal block allocation between 2006 and 2009, 1993 and 2004 and projects given under a government scheme.
The CBI may also inform the apex court of the permission sought from nine states that were reluctant in allowing the agency to conduct a probe in their jurisdiction.
The CBI had been directed to file chargesheets in all the cases finalised by it by the first week of March, but the agency moved a petition on March 4 seeking more time to file chargesheets.
