Another challenging year ahead…
The “Millennium Super Cycle” from 2003-
2011 was an unprecedented period of
growth and investment. The urgency to
bring production to market quickly
stretched people and project resources.
Now metal prices have declined and even if
some experts say that we are towards the
bottom of the market, the mining industry
is left with the legacy of high costs,
declining ore quality and less efficient
operating practices. More than ever, it
needs to focus on saving costs and improve
productivity.
Resource is a key asset and at Yaoni
Consulting we understand that geological
modeling and resource calculations are
crucial to help you minimize risks and make
the right decision at every stage of your
project.
That means apply state-of-the-art
methods, review current procedures,
identify possible avenues for improvement
and implement them.

As a Resource Geologist with 10 years operational experience, member of the Australasian
Institute of Mining and Metallurgy (AusIMM) and an expert with SURPAC, I can assist you with:
 Modeling your orebody in 3D using SURPAC ;
 Implementing the best resource
estimation technique for your
deposit, including conditional
simulation ;
 Writing technical reports
 Implementing SURPAC scripts to
automatize your procedures ;
 Reconciliation between estimation
and actual production ;
 Exploring effective solutions to
reduce the gap between estimation
and actual production (SMU size,
grade control spacing, possible bias
between drill holes…)
