Specifications for Metallurgic, Chemical Limestone
and Dolomite, Cement-Materials Mineral Exploration
1 Scope
This Standard specifies the degree of exploration study, exploration quality,
classification and type condition of resources/reserves, estimation of
resources/reserves, etc. for metallurgical, chemical limestone and dolomite, cement-
material mineral (calcareous material, clay material, and siliceous material)1); and
provides the deposit exploration type for analogy, and exploration engineering spacing
for reference.
This Standard is applicable to the metallurgic, chemical limestone and dolomite,
cement-materials mineral exploration, resource/reserves estimation; applicable to the
acceptance and review for the exploration design and exploration result report of
metallurgic, chemical limestone and dolomite, cement-material mineral; can also serve
as the basis for assessing and estimating the mineral resources/reserves during the
financing and the like activities of mining rights transferring, and mineral exploration
and mining.

1) Cement-material mineral generally includes. calcareous material – limestone, argillaceous limestone,
marble; clay material – clay, loess, mudstone, silt rock, shale, phyllite; siliceous material – sand,
sandstone.
3 Target Tasks of Exploration
The exploration work can be divided into four phases, namely, pre-survey, general
survey, detailed survey, and prospecting. The target tasks in each phase are as follows.
3.1 Pre-survey phase. through comprehensive study of geological data in the area,
preliminary field observation, very small amount of engineering verification, analogy
and prediction of the known deposit with the similar geological characteristics, propose
the area with larger mineral resources potentials for the general survey.
3.2 General survey phase. through adopting outcrop inspection, geological mapping,
limited number of sampling work, and the like field work against the area with larger
mineral source potentials confirmed in the pre-survey phase, generally find out the
geology and tectonics in the general survey area; generally understand the orebody
shape, production condition, and quality characteristics; generally learn exploring
technology of the deposit; conduct the mineral processing and separation analogy
study; propose whether it is worth for the further detailed survey, and encircle the range
for the detailed survey area.
3.3 Detailed survey phase. adopt several exploration methods and measures against
the detailed survey area encircled by the general survey; take certain network degree
system to sample; basically identify the geological and tectonic characteristics, and
control situation for the orebody, which mainly includes orebody shape, occurrence,
size, and mineral quality; basically confirm the continuity of the orebody; basically find
out the technical conditions of deposit mining; conduct the mineral processing and
separation analogy and laboratory flow test study; make the assessment for whether
it has industrial value or whether it can be used in the near future. If necessary, encircle
exploration range; and provide basis for pre-feasibility study, master mine planning,
and preparation of mine project proposals. For the mining areas that directly provide
mining and utilization, it shall meet the requirements of mine construction design.
3.4 Prospecting phase. through encrypting various sampling projects against the
exploration area proposed by the detailed survey, identify the deposit geological
characteristics in detailed; confirm the orebody shape, occurrence, size, change
regularity of down-strike and inclination, spatial location and ore quality characteristics;
confirm the continuity of orebody; find out the technical conditions of ore...
