COMET Strategy Pty Ltd focuses solely on
value creation through the provision of tools,
expertise and training for strategic analysis in
the mining industry.
SOFTWARE
In the 18 years since its initial development,
COMET Optimal Scheduler has been used on
more than 80 of the world’s most valuable
surface and underground mines and it is now
running in excess of 100,000 scenarios each
year for projects located in countries such as;
Australia, Brazil, Canada, Chile, Mongolia,
PNG, Philippines, Peru, South Africa, USA,
among others.
COMET Optimal Scheduler is an advanced
multi-policy schedule optimisation tool
developed to optimise both single mine and
complex combinations of surface and
underground mines using common
infrastructure. The objective of each
optimisation is to maximize NPV, taking into
account productivity, operational constraints
and economic conditions that may change
throughout the life of the project.
Our algorithms are unique in how they
simultaneously optimises multiple policies
such as pushback/strip sequences, variable
processing cut-off grades, haulage to multiple
destinations, stockpile creation and depletion,
process recovery (throughput/recovery
relationships), multiple ore types and any
number of processing facilities and methods.
COMET Optimal Scheduler is used on many
different types of projects including; copper,
gold, silver, platinum, uranium, bauxite, coal,
iron, diamonds, nickel, zinc, and molybdenum.
COMET ONE is the new on-line schedule
optimisation tool designed to simply and
freely help students understand how to find
and exploit the value drivers of a mine. This is
one way for COMET Strategy puts back into
the next generation of mining professionals.

Research and Development
SOFTWARE DEVELOPMENT
When very particular complexities are to be
modeled and optimised, COMET Strategy has
all the capabilities and experience to create
new ‘Custom Functions’ and software to
tailor the model as close to real to the
operation or project to be studied. The most
famous Custom Functions or algorithms
include:
• Fleet Replacement
• Grinding Adjustment
(Grinding Versus Recoveries).
• Incremental Distance to Waste Dump
(Waste Dump Optimiser).
GRADE ENGINEERING
COMET Strategy is currently working in
collaboration and as a member with CRCORE
on the Grade Engineering Program, with focus
in Mine Planning Optimisation with Grade
Engineering Techniques.
Grade Engineering Techniques include: Sensor
Based Sorting (Bulk Sorting and Particle
Sorting), Differential Blasting (Induced
Deportment), Grade by Size (Natural
Deportment), and Dense Media Separation
(DMS). COMET Strategy is the first company
with CRCORE to create a full optimisation to the
Long Term Mine Plan of an operating mine with
Grade Engineering Techniques. Please visit our
website to download the technical paper.
KEN LANE’S BOOK
COMET Strategy bases a large part of its work,
research and development, on Kenneth F.
Lane’s Cut-Off Grade theories. Lane’s theories
and work have been the base and foundation
for strategic mine planning worldwide for the
last century. COMET Strategy has recently
released the latest edition in two languages;
English and Spanish.
