Move more tonnes, with less uncertainty.

From pit to port, mining is a chain of variable, capital-intensive steps. Stochastix models the whole value chain, so you can de-risk expansions, right-size fleets and hit shipping targets, instead of planning on averages that quietly destroy value.

The challenge

Where value leaks across the mining value chain.

Grade & price uncertainty

Ore grades and commodity prices swing constantly. Plans built on a single expected case look fine on paper and underperform in reality.

Hidden bottlenecks

Pit, crusher, rail and port rarely choke where you expect. Spending capital to debottleneck the wrong step is an expensive way to learn that.

Fleet sizing & haulage

Truck and shovel fleets are enormous capital and operating costs. Over-sizing wastes money; under-sizing strands tonnes.

Stockpiles & blending

Meeting product specs from variable ore while juggling stockpiles and cut-off grades is a continuous, high-stakes balancing act.

How we help

Models for the whole pit-to-port chain.

We combine simulation, optimisation and forecasting into tools your planners and executives use to make confident, defensible calls.

Mine-to-port simulation

A discrete-event digital twin of the full chain, load, haul, crush, rail, stockpile, ship, to find the real constraint and test debottlenecking before you spend.

Fleet & blend optimisation

Optimal truck/shovel allocation, haul-route and dispatch decisions, plus blend and cut-off grade optimisation to hit specs at lowest cost.

Expansion & risk analytics

Monte Carlo NPV and throughput analysis across price and grade scenarios, so capital decisions come with a probability, not just a point estimate.

In practice

The kind of work we deliver.

Worked examples of how we approach mining and resources problems, and the decision each one informs.

Simulation

Mine-to-port debottlenecking

A full-chain discrete-event model of load, haul, crush, rail, stockpile and ship pinpoints the true binding constraint, which often isn't where it's assumed, so capital goes to the step that actually limits tonnes.

Optimisation

Haul-fleet optimisation

Mixed-integer optimisation of truck and shovel allocation across shift patterns and pit phases, validated against a simulation twin and stress-tested over price and grade scenarios.

Lower costsame tonnes, fewer truck-hours
Analytics

Expansion under price uncertainty

A Monte Carlo NPV model for a major expansion propagates commodity-price, grade and ramp-up uncertainty into a full distribution of outcomes, so the board sees the odds rather than a single point estimate.
