Project Case Studies
These case studies show how I work across three connected mining challenges: aligning mine delivery with downstream development, making resource uncertainty visible, and connecting technical evidence with investment value. Project details and figures are generalised where confidentiality applies.
Downstreaming Integration
Coordinating mine geology, ore supply, infrastructure, construction, and downstream requirements within a large integrated nickel-cobalt development.
Outcome: Contributed to programme completion approximately four months ahead of target while maintaining dilution at around 2% and strengthening operational safety performance.
Focus: Mine-to-Project interfaces · Ore Specification Control · Multifunction Coordination · Project Safety
Resource Risk Prediction
Investigating recurring differences between a resource model and production by combining reconciliation, drillhole-spacing analysis, density review, and field verification.
Outcome: Established a clearer and repeatable basis for identifying geological uncertainty, prioritising validation work, and improving confidence in resource and mine-planning decisions.
Focus: Resource Modelling · Ore Reconciliation · 3D Spatial Analysis · Geological QA/QC
Techno-Finance Integration
Connecting resource confidence, mine-development assumptions, project economics, regulation, and downside risk within a traceable mineral-investment evaluation.
Outcome: Applied the approach across more than 15 mineral-opportunity reviews and supported two completed acquisitions while also identifying opportunities requiring further evidence or a no-go decision.
Focus: Technical Due Diligence · Mine Economics · Scenario Testing · Investment Evaluation
Confidentiality: These case studies use public, personal, or appropriately anonymised information. Companies, sites, counterparties, commercial assumptions, and sensitive datasets are generalised or omitted.
