Ensure reliable grade control models are generated in a timely manner and made available to support effective and efficient planning and design of ore minable perimeters for open pit operations and ore minable stopes for underground operations, supporting achievable production budgets and de-risking delivery of the annual gold production budget in line with the Gold Mine Strategic Business Plan.
Responsibilities
- Foster Grade Control team compliance with site HSE policies, protocols and standards through active participation in geology toolbox meetings and monitoring of leading indicators such as Take5, workplace inspections, critical control verifications and safety observations.
- Develop the skills and technical capability of the grade control modelling team by assigning work, monitoring quality and progress, providing technical support, and recommending training programs aligned to business requirements.
- Lead and guide the site grade control team to ensure compliance with SOPs for grade control modelling workflows for both open pit and underground operations in line with AGA grade control modelling protocols, standards and QAQC requirements.
- Establish standard ways of working for the Gold Mine grade control team and closely monitor adherence to grade control workflow processes and modelling practices for both open pit and underground projects.
- Review generated grade control models, including validation of laboratory and drillhole data, interpretation of high-grade and low-grade wireframes, assessment of metal domains and trends, and review of geostatistical estimation parameters to support model reliability.
