Hi Mr Knight,
Indicated --
Quantity and grade, and/or quality, are
computed from information similar to that
used for Measured Resources, but the sites
for inspection, sampling, and measurement
are farther apart or are otherwise less
adequately spaced. The degree of
assurance, although lower that for
Measured Resources, is high enough to
assume geologic continuity between points
of observation.
Inferred --
Estimates are based on geologic evidence
and assumed continuity in which there is
less confidence that for Measured or
Indicated Resources. Inferred resources
may or may not be supported by samples
or measurements but the inference must
be supported by reasonable geo-scientific
data.
Reserve.
A Reserve is that part of the Resource that
meets minimum physical and chemical
criteria related to the specified mining and
production practices, including those for
grade, quality, thickness, depth; and can be
reasonably assumed to be economically
and legally extracted or produced at the
time of the determination. The feasibility of
the specified mining and production
practices must have been demonstrated or
can be reasonably assumed on the basis of
tests and measurements.
Proven Reserve --
That part of a Measured Resource that
satisfies the conditions to be classified as a
Reserve.
