PIDC undertook a major development program with USAID funding, and the services of foreign experts were acquired for the development of coal mines at greater depth. A scheme costing Rs. 16.7 million was executed between 1956 to 1965 for this purpose. This scheme was targeted to increase the annual production capacity to 300, 000 tons per annum. The proposed target could not be achieved due to a major geological disturbance/fault known as the main Makerwal. Maximum production of 218, 000 tons was achieved in 1967-68.

MCL was transferred to PMDC in 1974. PMDC initiated a major investment program to replace the old worn-out machinery. An expenditure of Rs. 24,308 million was made to develop drivage into the coal seam. In 1995 the MCL was privatized by the Privatization Commission of Pakistan.

At the time of the privatization of Makerwal Collieries Limited, the proved reserves of coal were negligible and no future planning could be done unless and until the geological investigations are carried out to establish the coal services and wages were arranged either from loan or sale of project assets. The deep sealed reserves below water level, and lack of proved reserves over employment at the project was the main hurdles in the way of efficient operation of the project.

The company had not been profitable for the last ten years. PMDC had been providing financial assistance since 1983 and as of late, the Privatization Commission was paying employees salaries. Due to recurring losses and insolvency, the company was not a good concern. The project was not financially viable at its present status.
