1 Application Scope
This Standard specifies the requirements for the exploration study level and control
level, exploration work quality, classification of mineral resources/reserves and type
conditions, estimation of mineral resources/reserves for kaolinite, bentonite and
refractory-clay mineral exploration; it proposes the ore deposit exploration types and
the reference exploration engineering intervals for analogic use.
This Standard applies to the exploration of kaolinite, bentonite and refractory-clay
minerals and the estimation of mineral resources/reserves; it applies to the acceptance
and appraisal of the geological reports of kaolinite, bentonite and refractory-clay
mineral exploration; it may also work as the basis for the assessment and estimation
of mineral resources/reserves in the activities including mining right transfer and
mineral exploration, development, financing and listing.

3 Purposes and Tasks of Exploration
The exploration work of kaolinite, bentonite and refractory-clay is divided into four
states, namely reconnaissance, general exploration, detailed exploration and
prospecting. The purposes and tasks of all stages are as follows.
-- Reconnaissance. in accordance with the areal geological study results and
through preliminary field inspections, tiny amounts of engineering verification,
analogies and speculations of known deposits of similar geological characteristics,
to come up with the areas of great potential of minerals for general exploration, in
order to provide basis for the general exploration work;
-- General exploration. for the areas of great mineral potential for general
exploration, using inspection, geological mapping, limited number of sampling
projects, to approximately identify the geological and structural conditions of the
areas for general exploration; to approximately master the morphology and
occurrence of ore body and ore quality characteristics; to understand the technical
conditions for mineral exploitation; to conduct analogical study of the processing-
dressing properties of minerals; to come up with whether it is worthy of general
exploration further or to circle out the ranges of the detailed exploration areas;
-- Detailed exploration. for the detailed exploration areas circled out in the general
exploration, using large-scale geological mapping and all kinds of exploration
methods and means including systematic sampling denser than in the general
exploration stage, to basically identify the geology, structure and morphology,
occurrence and size of major ore body and ore quality; to basically ascertain the
continuity of ore body; to basically identify the technical conditions for ore deposit
mining; to conduct analogies or optional tests and laboratory process test study
for the processing-dressing of ore; and to make an assessment whether there is
an industrial value. If necessary, circle out the exploration ranges for the use in
feasibility studies, drafting mining overall plans and compiling mining project
proposals. For the mining areas which are directly developed and utilized, the
degree of the processing-dressing property test shall meet the requirements for
the mine construction and design;
-- Prospecting. for the ore bodies of a known industrial value or the prospecting
areas circled out in the detailed exploration, by increasing all kinds of sampling
projects whose interval sha...
