The government announced on Tuesday that limestone will now be fully classified as a major mineral, removing earlier distinctions based on its use. This change is expected to improve the ease of doing business by allowing leaseholders to mine, sell, or use limestone without restrictions based on its end use. Previously, limestone was treated as both a minor and major mineral depending on how it was used. If used to make lime for building materials in kilns, it was classified as a minor mineral, but if used for making cement, fertilizers, chemicals, sugar, or steel, it was considered a major mineral.

To ensure a smooth transition, the Ministry of Mines issued an order on October 13, 2025, stating that all current minor mineral leases for limestone will now be treated as major mineral leases, without disruption. This decision followed recommendations from an inter-ministerial committee, which consulted with industry stakeholders. The change addresses the declining availability of limestone for lime-making, as most limestone is now used by industries like cement and chemicals.

By removing limestone from the minor minerals list, the government has met a long-standing demand from leaseholders, who can now freely sell limestone to cement and other industries. This move is expected to boost construction activity, create jobs, and support economic growth.
