SCHEDULE I
EVIDENCE OF MINERAL CONTENTS
Existence of mineral content will have to be established in an area for the
purpose of auction of Mineral Block by carrying out exploration as per the suggested
geological parameters and exploration norms given in Part-I, II and III of
Schedule-I.
Part – I
Definitions
1. The exploration for any minor mineral deposit involves two stages namely, General Exploration
(C2) and Detailed Exploration (C1). These stages of exploration lead to resource categories namely
Inferred Mineral Resource and Indicated/ Measured Mineral Resource respectively reflecting the
degree of geological assurance.
2. General Exploration (C2) involves the initial delineation of an identified deposit. Methods used
include surface mapping, pitting/ trenching/ drilling, followed by sampling for evaluation of
mineral quantity and quality (including mineralogical tests on laboratory scale if required), and
limited interpolation based on indirect methods of investigation. The objective is to establish the
main geological features of a deposit, giving a reasonable indication of continuity and providing an
initial estimate of size, shape, structure and grade.
3. Detailed Exploration (C1) involves the detailed three-dimensional delineation of a known deposit
achieved through sampling, such as from outcrops, pits, trenches, boreholes, shafts and tunnels etc.
Sampling grids are closely spaced such that size, shape, structure, grade and other relevant
characteristics of the deposit are established with a high degree of accuracy. Processing tests
involving bulk sampling may be required.
4. Mineral Resource is a concentration or occurrence of solid material of economic interest in or on
the earth‘s crust in such form, grade or quality and quantity that there are reasonable prospects for
eventual economic extraction. The location, quantity, grade or quality, continuity and other
geological characteristics of a Mineral Resource are known, estimated or interpreted from specific
geological evidence and knowledge, including sampling. Mineral Resources are subdivided, in
order of increasing geological confidence into Reconnaissance, Inferred, Indicated and Measured
resource categories which are defined as follows:-
(a) Inferred Mineral Resource is that part of a Mineral Resource for which quantity and grade or
quality are estimated on the basis of limited geological evidence and sampling achieved through
a stage of preliminary exploration. An Inferred Resource has a lower level of confidence than
that applying to an Indicated Mineral Resource and shall not be converted to a Mineral Reserve.
Jharkhand Gazette (Extraordinary), Wednesday, 23th January, 2019
4
The majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources
with continued exploration.
(b) Indicated Mineral Resource is that part of a Mineral Resource for which quantity, grade or
quality, densities, shape and physical characteristics are estimated with sufficient confidence to
allow the application of Modifying Factors in sufficient detail to support mine planning and
evaluation of the economic viability of the deposit. Geological evidence is derived from
adequately detailed and reliable exploration, sampling and testing and is sufficient to assume
geological and grade or quality continuity between points of observation. An Indicated Mineral
Resource has a lower level of confidence than that applying to a Measured Mineral Resource and
may only be converted to a Probable Mineral Reserve.
(c) Measured Mineral Resource is that part of a Mineral Resource for which quantity, grade or
quality, densities, shape, and physical characteristics are estimated with confidence sufficient to
allow the application of Modifying Factors to support detailed mine planning and final
evaluation of the economic viability of the deposit. Geological evidence is derived from detailed
and reliable exploration, sampling and testing and is sufficient to confirm geological and grade
or quality continuity between points of observation. A Measured Mineral Resource has a higher
level of confidence than that applying to either an Indicated Mineral Resource or an Inferred
Mineral Resource. It may be converted to a Proved Mineral Reserve or to a Probable Mineral
Reserve.
5. A Feasibility Study (FS) is a detailed comprehensive economic study of the selected development
option for a mineral project that includes appropriately detailed assessments of applicable
Modifying Factors together with any other relevant operational factors and detailed financial
analysis that are necessary to demonstrate at the time of reporting that extraction is reasonably
justified (economically mineable).
6. Feasibility Mineral Resource: A Feasibility Mineral Resource is that part of
Indicated/ Measured Mineral Resource which is not economically mineable as,
defined by studies at feasibility level. This material is identified as being possibly
economically viable subject to changes in technological, economic, and
environmental and/ or other relevant conditions.
7. Mineral Reserve is the economically mineable part of a Measured and Indicated Mineral Resource.
It includes diluting materials and allowances for losses, which may occur when the material is
mined or extracted and is defined by studies at Feasibility level as appropriate that include
application of Modifying Factors which are factors those are taken into consideration while
conducting a Pre-feasibility or feasibility study so as to convert Mineral Resources to Mineral
Reserves. These include, but are not restricted to, mining, processing, end use, cut-off grade,
threshold value, metallurgical, infrastructure, economic, marketing, legal, environmental, social and
governmental factors. Mineral reserve may further be categorized as:-
(a) Probable Mineral Reserve is the economically mineable part of an Indicated,
and in some circumstances, a Measured Mineral Resource. The confidence in
the Modifying Factors applying to a Probable Mineral Reserve is lower than
that applying to a Proved Mineral Reserve.
(b) Proved Mineral Reserve is the economically mineable part of a Measured
Mineral Resource. A Proved Mineral Reserve implies a high degree of
confidence in the Modifying Factors.
