Kimmer Economics
Open-pit economics for the block model you already have. Kimmer Economics turns a CSV block model into block values, cutoff grades, a discounted cash-flow with a Turkey-specific royalty model, and an optimized ultimate pit, all in a local desktop app. This is a pre-release alpha: the core economics engine is validated against published industry benchmarks, but the desktop app is still filling in reporting and export.
Block model in, pit economics out.
A tested economics engine handles the numbers, block values, cutoff grades, cash flow, and ultimate pit, so mine planners work with results, not spreadsheets full of band-aids.
Block economics engine
Computes per-block tonnage, revenue, and economic block value (EBV), then classifies ore vs. waste across the whole model, fast enough to sweep the entire block model at once.
Cutoff grade, four ways
Break-even cutoff in four variants, basic, stripping-ratio-adjusted, AISC-based, and in-situ dilution/recovery-adjusted, plus grade-tonnage curves sweeping 50 cutoffs and overall/break-even stripping-ratio analysis.
NPV/DCF with a Turkey royalty model
A discounted cash-flow engine with a fixed 25% corporate tax and a Turkish royalty table (Groups I–IV, ~8 named Group-IV metals, underground -50% and domestic-processing -75% discounts with an Au/Ag/Pt exclusion).
Ultimate pit & nested shells
Industry-standard ultimate-pit optimization finds the most valuable pit for your economic assumptions. A revenue-factor sweep generates nested pit shells with per-shell analysis for pushback planning.
Production scheduling
Two schedulers ship in the engine: a fast heuristic and an exact optimization for small models, so you can trade solve time against optimality.
Sensitivity & Monte Carlo
Tornado and spider diagrams, Monte Carlo with P10/P50/P90 and probability-of-positive-NPV, and a break-even solver, visualized in-app alongside an interactive 3D block/pit viewer.
From block model to pit shell in one workflow
Import a CSV block model with flexible column mapping (density and rock type optional, grid dimensions inferred from unique coordinates), compute block economics and cutoff grades, run the ultimate pit, and inspect nested shells and cash flow, all locally, with an interactive 3D viewer for cross-sections and bench-by-bench review.
