The restart of the Woodlawn volcanogenic massive sulfide (VMS) mine in New South Wales presented an uncommon geological and organisational challenge: rebuilding the full geology function while underground development, process plant recommissioning, and production ramp-up proceeded in parallel. In contrast to brownfields operations with mature technical systems, Woodlawn was effectively recommenced without an embedded geology operating model, integrated database architecture, or standardised workflows suitable for an active underground mine. This created a requirement not only to restore site-specific capability but to establish a modern geological framework that could be transferred across a growing multi-asset company. This paper presents the development and implementation of a modular nine-pillar geological operating framework at Woodlawn. The framework comprised: 1. Mapping and digital data capture. 2. Sampling and QA/QC. 3. Geological modelling and domaining. 4. Drill planning and execution. 5. Estimation and reconciliation. 6. Material tracking and stockpile control. 7. Operational readiness and mine-technical integration. 8. Capability and workforce development. 9. Continuous improvement and governance. Each pillar was designed to satisfy immediate operational needs while remaining site-neutral, interoperable and scalable across different commodities and mining methods. Implementation required sequential rebuilding of core technical foundations, including the drill hole database, core handling and photography systems, logging and domaining standards, ore flow tracking, and reconciliation workflows aligned with Parker-style F1, F2 and F3 factors (Parker, 2012). Digital tools, including tablet-based mapping, photogrammetry and machine-assisted core image workflows, were selected for both operational fit and future redeployment potential. By 2025, Woodlawn had transitioned from a restart project with fragmented legacy data to an operating underground mine supported by an integrated geology function. The principal outcome was not simply a set of site procedures, but a transferable geological operating model that linked orebody knowledge, operational control, reconciliation and governance. The Woodlawn case demonstrates that mine restarts can be used to establish scalable geological systems in parallel with production ramp-up, provided that system design is modular, disciplined and explicitly aligned with future multi-asset growth.
