Open-pit mine planning software that returns a practical plan in minutes

Pit selection, block scheduling and haulage usually mean three steps in three tools. Keeping them aligned as assumptions move eats a good share of any study.

Cognomine solves all three in a single pass. Ultimate pit selection decides what is economic to extract, the block schedule decides what gets mined when, and haulage decides how the material moves and what fleet that needs. Because they resolve together rather than one after another, there is one set of inputs to prepare and one result to defend.

Strategic planning has always been limited by what a solver can accept at once. To get a long-horizon answer back in reasonable time, operating detail gets dropped, and the plan that comes back is one a crew could not run as scheduled.

Cognomine keeps that detail in the solve: bench and phase sequencing, dig precedence, drill-and-blast lag, digger separation, slope constraints, haulage and processing capacity, grade targets and stockpile strategy, with the capital and operating trade-offs behind them. It runs in the cloud on quantum-ready algorithms, and runs cost nothing beyond the credit already on your account.

Test the price decks, the delayed capital project, the changed cut-off grade, then take your executives or clients a recommendation you can defend. Closing the gap between plan and practicality is what Cognomine is built for.

How the constraints are held →

We publish our benchmarks in full, including what they do not show: one against Google OR-Tools, and replays on two MineLib deposits.

Google OR-Tools. A full ten-year plan, benchmarked against Google OR-Tools on the same orebody, the same constraints and the same assumptions. Cognomine returned a plan in minutes. Google OR-Tools, given the same variables and the same constraint set, was stopped unconverged at 12 hours. The Cognomine plan returned $273M more discounted NPV, about 16% higher, on $149.5M less equipment capital, around 59% less, with a peak fleet of 2 diggers and 17 trucks against 5 diggers and 41 trucks.

MineLib. Published third-party solutions on public deposits, replayed under the physical constraints a real operation works under. On two deposits so far the published plans lost very different shares of their stated value, which is itself the finding.

Most of the block models that come into Cognomine belong to someone other than the person uploading them. The platform is built for that. Client data stays in Australia, is encrypted in transit and at rest, is isolated to your account, and is removed within 30 days after your entitlement ends.

You can hand results to a client read-only with no limit on recipients, and bring up to two additional authorised users in to work on the model alongside you. Nobody you share with has to buy anything. If a client's security team wants to review our controls before you upload, we will support that review.
