• Ensure all financial and productivity assumptions used in schedules reflect validated data, historical performance, and current operational constraints.
• Support the integration of cost inputs into Deswik schedules by providing validated rates, unit costs, and productivity metrics.
• Contribute to reconciliation processes across the medium-term horizon, including variance analysis between planned and actual costs, physicals, and productivity.
• Prepare regular cost modelling reports and dashboards to support operational reviews, business planning, and planning forums.
• Ensure cost assumptions reflect changes in infrastructure timing, development strategy, mining method adjustments, and operational readiness requirements.
• Coordinate with production engineering, LOM planning, mine operations, and finance teams to ensure alignment between physical schedules and financial expectations.
• Support capital planning by providing cost inputs related to development corridors, infrastructure requirements, sequencing options, and mining method scenarios.
• Maintain documentation, templates, and cost-modelling processes to support governance, repeatability, and audit readiness.
