CEC had categorised the mines in the area in three categories -- A, B and C. The mines in which there was least or no irregularities were categorised as 'A' and those with maximum illegalities were placed in category 'C'.
The apex court, while accepting the majority of the recommendations made by CEC since July 2011 on the mining issues in Karnataka, also said that illegal iron ore mining on the Andhra-Karnataka border would remain suspended till the demarcation of boundary between the two states is completed.
The illegalities referred to included illegal mining activities, allotment of huge quantities of iron ore at throw-away prices to private companies and an increase in rates at which iron ore was supplied to some other companies.
Earlier on September 3, 2012 the apex court had partially lifted its ban on mining operations in Karnataka, ordered more than a year ago, and gave a green signal for extraction of iron ores on 18 leases in category A mines, subject to certain conditions being fulfilled.
