GEOVIA Whittle 2026 – Strategic Open-Pit Mine Planning & Optimization

GEOVIA Whittle 2026 is a leading strategic open-pit mine planning and optimization software, developed by Dassault Systèmes under its GEOVIA brand. This application is essential for open-pit mining operations, consultancies, and resource geology firms focused on determining optimal pit limits and maximizing project economic value. It serves professionals involved in resource estimation, mineral economics, and corporate mining investment analysis, providing robust tools for complex, large-scale mine planning scenarios.

Advanced Pit Shell Optimization and Economic Analysis

GEOVIA Whittle 2026 provides industry-standard algorithms essential for defining the economic limits of open-pit mines. Its analytical power enables detailed financial assessments crucial for pre-feasibility and bankable feasibility studies.

Lerchs-Grossmann and Floating Cone Engines

At its core, GEOVIA Whittle 2026 utilizes the Lerchs-Grossmann (LG) algorithm for 3D pit optimization and the Floating Cone method for 2D analysis. These foundational algorithms are capable of processing large block models to generate optimal pit shells, considering defined economic parameters and geological structures. The software supports the creation of multiple nested shells, representing various economic scenarios or cut-off grades, which are critical for phased development planning.

Revenue Factor and NPV Maximization

The software is engineered to maximize project Net Present Value (NPV). This is achieved through detailed financial modeling that incorporates variable revenue factors, discount rates, and cutoff grades. By analyzing a range of economic conditions, Whittle 2026 identifies the pit design that yields the highest projected economic return, using discounted cash flow (DCF) analysis to account for the time value of money. This rigorous approach ensures that strategic decisions are based on sound economic principles.

Integrated Production Scheduling and Phase Design

Beyond determining the ultimate pit limit, GEOVIA Whittle 2026 offers sophisticated tools for translating optimization results into practical, phased mining plans. These capabilities are vital for guiding day-to-day operations and ensuring long-term project viability.

Nested Shells & Pushback Designer

GEOVIA Whittle 2026 features a new, interactive Pushback Designer tool, allowing for intuitive definition and sequencing of mining phases. This builds upon the software’s ability to generate nested pit shells, facilitating the creation of practical mineable areas. The Pushback Designer enables users to define sequences of operations, considering practical mining constraints and optimizing material movement strategies for each phase.

Multi-Stream Scheduling Flexibility

The software supports flexible production scheduling at various intervals, including annual and quarterly plans, essential for comprehensive resource management. It allows for the integration of multiple ore streams, accommodating different material types and quality specifications. This capability is crucial for effective ore blending strategies and stockpile management, ensuring that processing plants receive feed that meets operational requirements and maximizes downstream value.

Geology Integration and Reserve Reporting

Seamless integration with geological data and robust reporting functionalities are central to GEOVIA Whittle 2026’s utility in strategic mine planning. These features ensure that designs are geologically sound and compliant with industry regulations.

Block Model Compatibility

GEOVIA Whittle 2026 offers extensive compatibility with various geological block model formats. It supports direct import from industry-standard software such as GEOVIA Surpac, Dassault Systèmes’ Vulcan, Datamine, and Leapfrog Mining. This broad compatibility ensures that geologists and engineers can work with their existing data models, streamlining the input process and facilitating collaboration across different software platforms.

Compliant Reserve Reporting

The software aids in the generation of resource and reserve reporting that complies with international standards such as JORC (Australasian Code for the Reporting of Exploration Results, Mineral Resources and Ore Reserves) and NI 43-101 (National Instrument 43-101). It allows for the incorporation of modifying factors derived from the pit optimization and scheduling processes, ensuring that reported reserves reflect practical economic and operational realities.

Visualization, Scenario Management, and Automation

GEOVIA Whittle 2026 enhances user interaction and efficiency through advanced visualization, comprehensive scenario management, and powerful automation capabilities.

3D Pit and Drillhole Display

The software provides integrated 3D visualization tools for displaying generated pit shells, block models, and drillhole data. Users can visualize the results of optimization runs, examine the geometry of nested shells, and overlay key information such as grade distributions or fault lines. Cross-sections and detailed views further aid in the interpretation of geological data and the validation of pit designs, supporting effective communication of plans to stakeholders.

Python API & Batch Processing

GEOVIA Whittle 2026 includes a Python API, offering advanced users the ability to script custom workflows and automate repetitive tasks. This scripting capability supports complex analyses, batch processing of multiple scenarios, and integration with other planning tools. By leveraging the command-line interface and Python scripting, engineers can significantly increase the efficiency of their strategic planning processes and conduct more extensive sensitivity analyses.

Integration and Workflow Connectivity

GEOVIA Whittle 2026 is designed to integrate within a broader mining software ecosystem, enhancing overall workflow efficiency. Its connectivity allows for seamless data exchange and operational synergy across different phases of mine planning and execution.

The software offers direct integration with Dassault Systèmes’ GEOVIA Vulcan, enabling a streamlined workflow from block modeling and geological interpretation to pit optimization. It also exchanges data effortlessly with GEOVIA Surpac for geological modeling and mine design tasks. Cloud licensing options provide flexible access to the software, while its ability to interface with third-party scheduling tools ensures compatibility within diverse project environments. This interconnectedness is key for modern, data-intensive mining operations.
