Whittle 4.4

Whittle by Gemcom Software International Inc. is a strategic mine planning application widely used in the open‑pit mining industry to maximize project value from early scoping through feasibility and life‑of‑mine planning. It converts geological block models and economic inputs into optimized pit shells, practical mining phases (pushbacks), and long‑term production plans that respect operational and economic constraints.

Leveraging the Lerchs–Grossmann method and advanced optimization techniques, Whittle evaluates cut‑off grades, blending and processing limits, stockpiling strategies, and multiple price and cost scenarios to identify the most valuable mining sequence. It supports sensitivity and risk analysis for commodity prices, recoveries, slopes, and costs, providing clear insight into net present value (NPV), cash flow, and project robustness. Results are easy to compare across scenarios, and data integrates with common geology, design, and scheduling tools to streamline handoff between technical teams.

Key capabilities:

• Ultimate pit limit optimization and nested pit shells
• Pushback/phase generation and stage refinement
• Cut‑off grade optimization and stockpile modeling
• Constrained long‑term scheduling with mining, processing, blending, and product quality targets
• Sensitivity and risk analysis for prices, costs, slopes, and recoveries
• Reporting and interoperability within standard mining software workflows

Ideal users include mine planners, strategic planners, project evaluators, and financial analysts working on open‑pit evaluations and optimization.
