Estimation parameters are determined using
geostatistics as a guide, with consideration of
geological/structural analysis of ore geometry when available.
Ordinary Kriging, Inverse Distance, and various forms
of Indicator Kriging have all been utilized; all using
appropriate geologic controls.
Results are validated graphically and categorized by
confidence classification (measured-indicated-inferred) and
other relevant categories (oxidation, RQD, etc.)
Results are fully documented with itemized file lists,
parameter tables, estimation scripts, etc. so that revisions
can happen easily.
Our estimates have been confirmed by third party audits
and reconciliation studies on several properties.
