the precipitated minerals (minerals) is one of the natural wealth
influential in the national economy. Therefore efforts
to determine the quantity and quality of mineral deposits that should
always worked with a higher degree of certainty, in line with
stages of exploration. The more advanced stage of exploration, the greater
the level of confidence in the quantity and quality of mineral resources and
backup.
Based on the exploration phase, which describes the level
belief in its potential, do business grouping or classification
mineral resources and reserves.

Basic or classification criteria in a number of countries, especially the level of
geological confidence and economic feasibility. It was pioneered by the US Bureau
of Mines and the US Geological Survey (3), which until now still practiced
by countries with important mining industry like Australia
(2) United States (1), Canada and others. These countries
follow the classification of proved reserves (proven) and probable (probable) of
Securities and Exchange Commission in the United States (4). trust
United Nations (UN) in this case the Economic and Social Council (Economic
and Social Council) has prepared proposals reserve classifications and
Mineral resources that are simple and easily understood by all
party (5). In addition to the above criteria, the UN also uses economic
market (market economy) as one of the criteria.
In Indonesia, a problem that there are still non-existent classification
mineral resources and reserves were raw so that the various parties
government agencies and mining companies use
classification alone, which is considered the most appropriate classification
with the properties of mineral deposition and kebijakasanaan in
the company. The result is the statement of the quantity and
quality mineral resources or reserves often create confusion,
especially if the statement was not accompanied by a detailed explanation
regarding the classification criteria.
With regard to the fact mentioned above, the Government of Indonesia in
this case the Ministry of Mines and Energy sees the need for
draw up a standard classification that can be used to
classifying the types of mineral resources and reserves and
specify the criteria used for the grouping.

Classification of Mineral Resources and Reserves is a process
collection, filtration and processing of data and information from a
mineral deposits to obtain a quick overview of the
the precipitate was based on the criteria: the belief in geology and mining feasibility.
The criteria are based on the beliefs of geological exploration phase which includes
review the survey, prospecting, general exploration and detailed exploration
Mine eligibility criteria based on economic factors, technology,
regulations / legislation, environmental and social (economic,
technological, legal, and social environment factor).
Mineral Resources (Mineral Resources) are deposits of minerals
expected to be used in practice. Mineral resource
certain geological confidence can turn into a backup after
conducted feasibility study and meet the criteria are eligible
mine.
Reserves (Reserve) is a mineral that has been known to precipitate size,
shape, distribution, quantity and quality and that is economically,
technical, legal, and social environments can be mined at the time
the calculation is done
