ORDER
WHEREAS, the Mines and Minerals (Development and Regulation) Act, 1957
(hereinafter, ‘the Act’) was enacted to provide for development and regulation of
-mines and minerals in the country.
2. AND WHEREAS, minor minerals are those minerals which are specified or
notified under section 3(e) of the Act.
3. AND WHEREAS, the mineral ‘Limestone used in kilns for manufacture of lime
used as building material’ was declared as minor mineral vide Notification No.
G.S.R. 436, dated the 18' June, 1958 as amended by Notification No. G.S.R. 1199,
dated 12th September, 1961 and further superseded by Notification No. G.S.R.
786(E), dated 23rd August, 1989 in exercise of the powers conferred by section
3(e) of the Act. Limestone when used for any other purpose is a mineral other than
minor minerals (hereinafter, ‘major minerals’).
4 . AND WHEREAS, an Inter-Ministerial Committee was constituted on 4h
March, 2024 in NITI Aayog on Mines and Minerals Sector. The said Committee in
its report dated 4th November, 2024 has observed that presently, use of limestone
in making lime has significantly reduced and most of limestone is used in cement
manufacturing and in chemical industries, smelters, fertilizer unit, sugar factory etc.
Considering that limestone is widely available in many parts of the country, and
given its use predominant in cement industry, there appears compelling reason to
classify limestone as major minerals. Accordingly, the Committee recommended
that entry regarding limestone in notification of minor minerals may be deleted and
all minor mineral leases of limestone may be converted as major mineral leases.
5. AND WHEREAS, the Central Government in exercise of the powers conferred
by section 3(e) of the Act has amended the notification No. G.S.R. 786(E), dated
23rd August, 1989 to remove ‘Limestone used in kilns for manufacture of lime used
as building material’ from the list of minor minerals vide Notification No. G.S.R 751
(E) dated 10th October, 2025. Therefore, on and from 10th October, 2025, all type
of mineral Limestone is a major mineral.

6 . AND WHEREAS, as per Section 13 of the Act, the Central Government is
empowered to make rules in respect of major minerals. The Central Government
has framed the Minerals (Other than Atomic and Hydro Carbons Energy Minerals)
Concession Rules, 2016 (hereinafter, ‘MCR, 2016’) in exercise of the powers
conferred by section 13 of the Act.
7 : AND WHEREAS, the Central Government has framed the Mineral
Conservation and Development Rules, 2017 (hereinafter, ‘MCDR, 2017’) in
exercise ofthe powers conferred by section 18 of the Act in the interest of
conservation and systematic development of minerals in the country.
8. AND WHEREAS, pursuant to the reclassification of minor mineral Limestone
as major minerals, the existing minor mineral leases of limestone will be regulated
in accordance with the provisions of the Act and the rules framed thereunder in
respect of other major minerals. As such, the lease period of the existing minor
mineral leases of Limestone shall be governed as per section 8A of the MMDR Act
on classification of Limestone as major mineral. Thus, lease period of mining
leases granted after the commencement of the MMDR Amendment Act, 2015 shall
be for the period of 50 years. Further, in case of mining leases granted before the
commencement of the MMDR Amendment Act, 2015, the lease period shall be
extended and be deemed to have been extended up to a period ending on 31st
March, 2020 (for merchant mines) or 31st March, 2030 (for captive mines) with

completion of renewal period, if any, or a period of 50 years from the date of grant
of such lease, whichever is later, subject to the condition that all the terms and
conditions of the lease have been complied with.
9 . AND WHEREAS, various issues related to application of existing rules for
major minerals may arise due to transition of the existing minor mineral mining
leases to major mineral category, such as period for registration of lease holders
with the Indian Bureau of Mines, approval of mining plan, royalty rates applicable,
compliance of various requirements, etc. Accordingly, it is considered necessary to
make certain transitory arrangements for smooth transition of the existing minor
mineral mining leases of Limestone to major mineral category.
10. AND WHEREAS, it is also noted that certain applications for grant mineral
concession in respect of minor mineral Limestone were pending before State
Governments that, will be affected by categorization of ‘Limestone used in kilns for
manufacture of lime used as building material’ to major mineral. Accordingly,
a transitory period is required to be provided to the applicants that have already
