"mineral resource" means a mineral deposit that may eventually be
economically and legally extracted. Mineral resources are restricted to the portion
included in the life of mine
plan and are sub-divided into:
?inferred mineral resources?: a mineral resource where sampling and other data
are insufficient to permit interpretation of the geological framework or to enable
prediction of the geological and/or grade continuity with other than a low degree of
confidence;
?indicated mineral resources?: the spacing of sampling and geological data
points affords a degree of confidence high enough to give a reasonable indication
of geological and/or grade continuity;
?measured mineral resources?: the sampling and geological data points are
spaced such that geological and/or grade continuity may be estimated with a high
degree of confidence.
?mineral reserve?
?mineral reserve? means that part of a mineral resource which could be technically,
economically and legally mined under conditions existing at the time of reporting.
?mineral reserve (South African operations)?
?mineral reserve (South African operations)? means the payable component of the mineral
resource as calculated under conditions pertaining in December 1998. It should be noted
that these conditions will change and therefore pay limits will change in the future. In
addition, the long-range mining plan will mine a mixture of 'payable reserve' and 'marginal
resource'. Mineral reserves are sub-divided into:
?probable mineral reserve?: that part of the indicated mineral resource above a
pay limit calculated in December 1998.
?proved mineral reserve?: that part of the measured mineral resource above a
pay limit calculated in December 1998.
?mineral reserve (other AngloGold operations)?
?mineral reserve (other AngloGold operations)? means the estimated tonnage and grade
which are capable of being delivered to the treatment facility and includes allowances made
for additional dilution or gold loss.
?mineral reserve (Ergo)?
?mineral reserve (Ergo)? means the estimated tonnage and grade of the mineral resource in
the slimes dams and sand dumps, or portions thereof, that are currently technically and
economically treatable.
