Studio Maxipit

Studio Maxipit finds optimum pit limits and block-by-block extraction sequence for given geological and economic parameters. Studio Maxipit performs two types of optimization:

A Lerchs-Grossmann search to find the economic limits to open pit and NPV optimizing extraction sequence.
A Resource-based search to find optimum blended pit and extraction sequence.

Geological Risk Enabled Studio Maxipit imports the conditional simulation data to generate Risk Rated Pits and probability distributions of profits and NPV for any extraction sequence.

Studio Maxipit Input

A block model defining geological and geochemical properties of the mineral deposit.
Economic parameters such as metal prices, mining and processing costs, metal recoveries, etc.

Studio Maxipit Output

Pit topographies (surfaces) viewable and exportable as 3D objects, contours and block model fields. In addition to Lerchs-Grossmann ultimate pit and phases, Studio Maxipit can generate any configuration of intermediate pits from NPV optimal and blended extraction sequences.
Customizable spreadsheet reports and charts including pit specific reports, bench reserves and grade curves.
Viewable and exportable block models with cost/revenue information and pit definitions.

Optimization Tools

Economic Model: calculate revenues, costs, metal recoveries and overall block values for multiple products (metals), multiple rock types and multiple processing methods. The application provides support for spreadsheet type formulas for cost and recovery calculations.
LG Pit Optimizer: generate Lerchs-Grossmann ultimate pit and phases, and an NPV maximizing extraction sequence.
Blended Pit Optimizer: generate optimal blended pit within the maximum resource or LG ultimate pit, and an optimal blended extraction sequence. The extraction sequence can be used to obtain intermediate blended pits.

Reports and Charts

Studio Maxipit displays reports in built-in spreadsheets. Studio Maxipit reports include fixed content optimization summaries and customizable reports on optimization results, bench reserves and grade curves. Customization options include:

Selecting which data columns to display and the order in which they are to be displayed.
Defining new data columns with spreadsheet type formulas.
Modifying report look in ways typical for spreadsheet applications.

Any report data column or a combination of columns can be charted with the built in charting application.

Visualization

Studio Maxipit supports visualization in 2D and 3D of all objects it generates and imports including block models, surfaces and digitized outlines. 3D windows allow you to manipulate the objects visually in a CAD like manner, query the objects for data, animate and insert smart plot items like text boxes, scale bars, coordinate grids etc. All surfaces can be rendered in the usual 3D manner and contoured, formatted and animated using a range of tools.

External Data Sources

Block models with geological data, surfaces and polygonal outlines can be imported from many external sources like text files, data bases tables, spreadsheets, AutoCAD etc. Special facilities are provided for importing and refreshing data from Datamine and Medsystem files. All objects generated by Studio Maxipit can be exported to third-party applications.
