Services · Testwork & Feasibility
Prove your process works before you commit capital.
Bench-to-pilot metallurgical testwork, process simulation, mass & energy balances, and bankable feasibility studies. We take you from ore / feed characterisation to an investor-ready DFS with engineering handoff package.
What we deliver
Six offerings clients buy individually or as a packaged programme.
Bench-scale testwork
Batch and continuous trials in our lab — atmospheric / pressure leach, SX-EW rougher loadings, solvent screening, reagent optimisation. 15–500 g feed per variable. 4–8 weeks per campaign.
Pilot-scale integrated runs
15–200 kg integrated circuit campaigns — leach, solid-liquid separation, SX, EW / precipitation. Minimum 100-hour continuous operation to generate design data.
Process modelling & simulation
Rigorous unit-op modelling in HSC Chemistry, METSIM, and Aspen Plus. Kinetics, speciation, residence-time distribution, heat integration.
Mass & energy balance
Design-basis M&E balance with full PFD and preliminary P&ID set. Equipment sizing, utility loads, effluent summary, reagent schedules.
Techno-economic analysis
CAPEX (Class 3–4 AACE) and OPEX models with sensitivity on feed grade, reagent price, energy, and recovery. NPV, IRR, payback, breakeven analysis.
Bankable Feasibility Study
JORC / SAMREC / NI 43-101-aligned DFS / BFS reports for investor due diligence, debt financing, and board approval. Includes risk register and execution plan.
Our methodology
A structured 4-phase approach — predictable timelines, clear decision gates.
Scope & baseline
Kickoff, feed / ore characterisation (XRD, SEM-EDS, chemical assay), literature review, test matrix design.
Bench testwork
Parallel batch runs screening leach conditions, reagent types, kinetics. Statistical DoE where applicable.
Pilot campaign
Integrated circuit operation. Steady-state sampling. Data reconciliation. Equipment performance validation.
Report & model
Final technical report, M&E balance, PFD / P&ID package, TEA, financial model, risk register. Board-ready.
What you take home
Every engagement ends with an engineering handoff package that the next phase — FEED, EPC bid, debt lender, or internal board — can pick up and act on without further interpretation.
- Assay certificates (CoA) for all feed, intermediate, and product streams
- Process flow diagram (PFD) + preliminary P&ID set
- Mass & energy balance (Excel-native, scenario-switchable)
- Equipment list with preliminary sizing + duty
- Process description document (what runs where, why)
- CAPEX estimate (Class 3–4 AACE, ±20–30% accuracy)
- OPEX model with reagent / energy / manpower / maintenance build-up
- Financial model (NPV, IRR, payback, sensitivities)
- Risk register with mitigation plan
- Final DFS / BFS report (investor-ready)
