Geology

The Z* Principal Analysts are all geologists with extensive experience in mineral resource estimation.
This combination ensures that fundamental components of the geological model are incorporated in the final mineral resource estimate. In this regard Z* firmly believe in forging a close working relationship with the project geologists as the geological model is the foundation of any mineral resource estimate.

THE APPLICATION OF GEOLOGY FOR OPTIMAL MINERAL RESOURCE ESTIMATION

All mineral resource estimation should be undertaken in accordance with the geological model on both a regional and local scale. Of particular importance is the emplacement, depositional and/or structural history which will determine the estimation domains and their boundary conditions and thus ensure correct partitioning of data.

GEOLOGICAL ZONATION

It is imperative that mineral resources are estimated in homogeneous zones that are typically defined by the geology. However, cognisance must also be given to the correlation between geological zones and the associated variability expected in the grade data. A thorough understanding of this mineralisation model is key to accurate estimation of the mineral resource.  Z* have extensive experience in applying interpolation solutions to refine geological boundaries.

OPTIMISING DRILLING PROGRAMMES

It is important to optimise geological drilling campaigns to ensure that a cost effective programme has been planned. It must also be remembered that a range of variables may be collected from geological delineation drilling e.g. density measurements or grade data. It is important that these programmes are optimised for the full range of parameters and not driven by a single requirement e.g. pierce points for a deposit boundary. Z* have extensive experience in optimising multivariable sampling campaigns.
