Specifications for iron, manganese and
chromium mineral exploration
1 Scope
This standard specifies the specifications of geological exploration for iron,
manganese, chrome minerals, including scope, normative references,
objectives and tasks of exploration, degree of investigation and study,
requirements for exploration control, exploration work and quality requirements,
feasibility evaluation, classifications of mineral resources/reserves, type
conditions, requirements for mineral resources/reserve estimates, etc.
This standard is applicable to geological exploration of iron, manganese and
chrome ore as well as the mineral resource/reserve estimate. It is also
applicable to the inspection and evaluation of exploration reports of iron,
manganese, chrome mineral. It may also be used as the basis for evaluating
and estimating mineral resources/reserves in such activities as mining rights
transfer, financing, fund-raising, stock listing for mineral exploration and
development.

3 Purpose and task of exploration
3.1 Pre-review
Through comprehensive study on geology, geophysical exploration,
geochemical exploration, remote-sensing in the region, preliminary field
observations, a very small number of engineering verification results,
comparison with deposits of known similar geological features, propose the
select prospecting areas, to carry out pre-review work. Make evaluation for the
geophysical anomalies, geochemical anomalies, remote-sensing anomalies,
mineralization points, ore deposits which have ore-forming conditions in the
pre-review region, to initially understand their characteristics and distribution
ranges, to provide a basis for further general check.
4.1.2 General review stage
Collect such data as geological, mineral, geophysical, geochemical, remote-
sensing geology, to understand regional geological features and prospects for
mineralization. Roughly identify the strata, lithology, thickness, occurrence,
distribution in the reviewed region. Roughly identify the distribution, scale,
occurrence of larger folds, faults, fracture zones. Roughly identify the type,
quantity, form, distribution of intrusive rocks or eruptive rocks. Evaluate all kinds
of geophysical anomalies, geochemical anomalies, remote-sensing anomalies,
ore deposits or mineralization points, to roughly identify their output
characteristics and distribution range. For mineral deposits (body) with further
working value in the region, it shall roughly identify the distribution, quantity,
location of occurrence, thickness, scale, occurrence, ore quality. It shall roughly
understand the development of the oxidation zone of the deposit (body), to
provide basis for further detailed review work.
4.1.3 Detailed review stage
4.1.3.1 Regional geology: Further study such data as the stratum, structure,
magmatic rocks, metamorphic rocks, minerals related to mineralization in the
region. Based on such data as geophysical, geochemical, remote-sensing
geology, clarify the location, regional geological features, mineralization
conditions, mineralization prospects of iron, manganese, chromium minerals in
regional structures as well as the major minerals in the region.
4.1.3.2 Mining ...
