Life of Mine (LOM) Final Landforms

Many mine owners estimate their rehabilitation liabilities using spreadsheets that apply a simple unit rate to disturbed hectares. While quick, this method often overstates costs by applying inflated allowances, or understates liabilities by ignoring true cut/fill movements and machine productivity. Either way, it leaves mine operators exposed to inaccurate provisioning, regulator scrutiny, and unexpected closure costs.

Our approach is different.

We create 3D digital terrain models (DTMs) that represent the final closure landform.

These DTMs are integrated into our construction simulation software to calculate true cut and fill volumes with engineering precision.

Using these volumes, we model the actual earthworks construction costs, incorporating:

· Dozer productivity curves,

· Material movement vectors (3D) across the surface,

· Realistic production rates and machine effort.

The result is a step-change in Mine Closure Cost accuracy:

· Credible earthwork figures for Mine reshaping  that withstand regulator and auditor review.

· Cost estimates tied to engineering reality, not broad spreadsheet formulas.

· The ability to test alternative closure designs in advance and identify cost  -saving opportunities before committing to construction.

· A defendable financial basis that strengthens closure plans, ESG reporting, and investor confidence.
