The Snly lntegrated, End-to-end Geology andMine Planning Solution for Stratified Deposlts

Gemcom Minex" is the only integrated

end-to-end software specifical ly

designed for stratified deposits. Fully

integrating all aspects of mining from

exploration through rehabi litation,

Minex ensures that your resources

are evaluated accurately and mined

efficiently, improving your productivity

and profitability throughout the mining

lifecycle. Developed in partnership

with the mining industry, the softwareis employed by the world's largest

mining companies.

Geological Modelling andResource EvaluationThe basis of any mine plan is areliable geological model. Minex offerscomprehensive tools to help geologists

manage data, model and quantify

stratified deposits, with support foreven the most complex faults.

lntegrated Data Management

"^:' Connect seamlessly to corporateborehole data storage systemsincluding Microsoft@ Access@ and

SQL Server@, Oracle@, and acQuire-'.

-"r Comprehensive tools facilitate datavalidation, auditing and resourcereporting to meet stock exchange

and reporting requirements.

""':t lmport grids from space and tabdelimited text files.

'*:. import and export Vulcan and

Carlson grid files and seam modelsas well as string data in AutoCAD@,

including its 2010 file format.

""i' Manage the location of project inputand output files using Minex's filemanagement tools.

Modelling

The key to accurate geological

modelling is effective interpretation.Minex uses all available data (i.e.geophysics, qual ities, lithology,

washability, and structural) to correlateand interpret the deposit.

""ir Repeatable, fast and accuratemodelling tools build entiremodels, including seam floor,

thickness, quality and othersurfaces in minutes. Specialisedtools for deposits with faultsallow accurate modelling of

inclined or curved faults, in normal

or reverse fault environments.

'-':r Model the complete coal wash curve

so that yield, ash and other analyses

can be estimated across the entire

deposit, and used in resource and

reserves reports to simulate plant

processes by area or schedule time.

'-'i Multiple industry standard

estimation tools, including an

interface to GSLIB for kriging and

conditional simulation.

""r Variogram modelling includes

dynamic lag adjustment to help

identify the best variograms forthe data.

-":' Validation tools including Jack Knifing

to help ensure confidence in theaccuracy of your geological models.

""i. Contouring, sectioning, 3D borehole,statistics and histogram displays tomaximise resource presentation

to managers, mining engineersor investors.

Mine PlanningMinex mine planning functions are

integrally linked to the geological

model. Planning starts by defining the

economic or best areas, so these areas

can be targeted during the subsequentpit design phase. Once designed, the

reserves and quality data are stored ina database to provide fast access forviewing, editing and manipulation.

Optimisation

-* The Minex Pit Optimiser locates andgenerates a final pit that is break

even at its limits, using the well-knownLerchs Grossman (LG) algorithm.

*'i Pit optimisation is ideal where pits

are deep and the material in thesloping final highwall makes a verticalanalysis difficult. For simpler flat lying

deposits Minex provides both verticaland inclined strip ratio calculations.

Open Pit Mine Design

'^: Powerful and easy to use Pit andRamp Design tools allow manualor automatic generation of pitsor dumps. Ramps are generated

as the pit or dump is created,providing instant visualisation ofyour project.

'-l Design a road or spoil pile on anyexisting mine topography, and easilypatch this into existing surfaces.

-t Mine designs are integratedwith the geological model and

optimisation output, enablingfast, accurate and timely designs.Minex dissects the deposit into a

set of mining volumes using theintersection of benches, strips and

blocks with the geological model.

Underground Mine Design

-'i Create detailed underground minedesigns using a set of rich and

interactive tools that provide instantvisualisation of your design asit unfolds.

'*i Using the Underground QuickLayout tool, create panels foreither longwall or bord andpillar layouts based on panel

configurations and working typeswith just a few keystrokes.

""s' Display your mine design using theUnderground 3D Reserves Displaytool and colour each block basedon a single color, working type or aquality variable.

Short-term Production

Minex provides you with a number ofdaily production tools:*'r Users can interface with a variety of

modern Survey GPS instruments todownload from the field, or uploadfor peg out.

Mine SchedulingEffective mine scheduling is a criticalpart of any mining operation. Smartscheduling of layered deposits, usingtools specifically designed for thetask, can be the difference betweenan operation being viable, and one

being marginal or losing money. Minexprovides numerous scheduling tools
