Principal Specialist, RPEE

RPEE Definition & Optimization

• Lead the development and application of RPEE criteria across open-pit and underground deposits.
• Perform and review pit optimizations, underground stope optimizations, and mineable shape analyses at a resource level.
• Ensure that all resource constraints are technically defendable and economically realistic.

Resource Classification Support

• Provide technical input into Mineral Resource classification by defining appropriate mining assumptions and extraction constraints.
• Ensure consistency in RPEE application across sites and projects.

Internalization of Technical Capability

• Reduce reliance on external consultants by delivering in-house pit and stope optimization work.
• Act as the internal technical authority for RPEE-related matters, peer-reviewing both internal and externally generated work.

Cross-Functional Integration
• • Work closely with geology, mine planning, and metallurgy teams to align RPEE assumptions with realistic mining and processing scenarios.
• • Support early-stage project evaluations, development studies, and long-term planning exercises.
Governance, Assurance & Documentation

• Ensure RPEE workflows are documented, auditable, and consistently applied.
• Support internal reviews, audits, and technical governance processes related to Mineral Resource reporting.
• Mentor geologists and engineers in RPEE concepts, optimization techniques, and resource-level mining assumptions.
• Contribute to building long-term internal capability in resource development and evaluation
