Transformation by design.

We help mining and critical minerals companies connect strategy, technology, and behaviour — turning transformation intent into measurable results.

Strategy × Execution Process systems & design Techno-economic modelling CFD & process simulation

Model before you decide

Connect design choices to value, cost, and risk.

Decision quality

From strategy to operation — decisions grounded in data and context.

Systems that shape behaviour

Design operating systems that make change sustainable.

From concept to operation

R&D, scale-up, and integration across critical minerals value chains.

Where we create value in critical & strategic minerals

Strategic transformation

  • Reframing how value is created across mining and critical minerals
  • Connecting corporate strategy to technical and organisational systems
  • Designing pathways for scalable, sustained change

Deep technical capability

  • Process systems engineering & metallurgical design
  • Integrated modelling across the mining value chain
  • Technology development from concept to operation

Simulation & TEA

  • Process + CFD modelling for copper, nickel, lithium, and REEs
  • Techno-economics & risk across project options
  • Sensitivity & scenario analysis for investment decisions

The global energy transition depends on secure, responsible supply of critical minerals — copper, nickel, lithium, and rare earths. Persephone helps companies translate that strategic imperative into actionable design, modelling, and development decisions.

The API between startups and operators

We bridge innovators and mining companies — translating real operational needs into credible technology pathways. Persephone helps startups become deployment-ready and enables operators to source, trial, and scale what matters most in the critical minerals ecosystem.

How we do it

Problem definition

Sharp, actionable operator briefs aligned to value levers.

Ecosystem mapping

Connecting the right labs, OEMs, and partners to accelerate validation.

Integration readiness

Ensuring safety, maintainability, and operational integration.

Scale-up proof

From first trial to full deployment — with clear KPIs and verified value.

Modelling & simulation — the decision engine

Connect technical choices to business outcomes. From species-level chemistry and techno-economics to CFD of heaps and hydromet circuits, our models help reveal trade-offs and optimise designs before steel is cut.

Techno-economics

NPV, IRR, constraints, sensitivities, and project trade-offs.

Process simulation

Steady-state & dynamic flowsheets across hydromet and pyromet systems.

CFD & transport

Heaps, reactors, heat & species transport for critical minerals processing.
