accuracy
/confidence
Resource estimate, as well as, the approach
or procedure deemed appropriate by the
Competent Person? [For example, the
application of statistical or geostatistical
procedures to quantify the relative accuracy
of the resource within stated confidence
limits, or, if such an approach is not deemed
appropriate, a qualitative discussion of the
factors which could affect the relative
accuracy and confidence of the estimate.]
Does the statement specify whether or not it
relates to global or local estimates, and, if
local, have the relevant tonnages or volumes,
which should be relevant to technical and
economic evaluation been stated?
[Documentation should include assumptions
made and the procedures used.]
Have the statements of relative accuracy and
confidence of the estimate been compared
with production data, where available?

4.0 - Criteria for the Estimation and Reporting of Ore Reserves
Item Criteria Essential Reporting Queries
4.1
Mineral
Resource
estimate for
conversion to
Ore Reserves
4.2 Study Status
Is there a description of the Mineral Resource
estimate used as a basis for the conversion to
an Ore Reserve?
Is there a clear statement as to whether the
Mineral Resources are reported additional to,
or inclusive of the Ore Reserves?
Was the type and level of study undertaken to
enable the conversion of Mineral Resources
to Ore Reserves denoted?
[The Codes do not require that a final
feasibility study be undertaken to convert
Mineral Resources to Ore Reserves, but it is
required that appropriate studies have been
carried out to determine a mine plan that is
technically achievable and economically
viable, and that all Modifying Factors have
been considered.]
