OceanaGold is a growing mid‑tier gold and copper producer listed on the Toronto Stock Exchange (TSX). With four operating mines – Haile in the USA, Didipio in the Philippines, and Macraes and Waihi in New Zealand – we are committed to safe, responsible mining that generates strong returns and supports sustainable development.

Job Description

Working an 8 / 6 roster, days only, you will manage the stability of the underground working environment through systematic data collection, geotechnical analysis, planning and underground inspections in line with the Ground Control Management Plan (GCMP).

• Photograph and maintain a record of all stope brows and other geotechnically relevant items of interest.
• Review geological mapping and operational ground condition records daily, ensuring that identified structure and hazardous ground conditions are communicated to operations and that mitigation plans are developed and understood.
• Undertake routine geotechnical monitoring using a TARP and risk‑based priority system.
• Interpret and analyse monitoring data to identify trends, hazardous conditions and predict upcoming issues.
• Delineate, secure and manage areas of hazard with appropriate signage and restrictions.
• Conduct all required QAQC on ground support as outlined in the Ground Control Management Plan.
• Carefully review daily / weekly / monthly operational plans and Mining Instructions (MI) to ensure anticipated geotechnical conditions have been considered and that suitable mining methods and ground support has been specified.
• Install and maintain underground geotechnical monitoring systems and equipment including convergence points, Cyclops, MPBX, smart cables and LiDAR scanners, ensuring equipment is properly serviced, calibrated and maintained in a reliable condition to support critical mining functions.
