Overview:
We
are seeking a highly experienced Deputy Geology Manager to support the Head of
Geology at one of Papua New Guinea’s most structurally complex, high-grade
underground gold operations. This is a senior technical and leadership role,

Reporting
to the Head of Geology, the Deputy Geology Manager will:
- Provide geological leadership across mine geology, resource geology, and exploration, ensuring consistent interpretations, datasets, and 3D models across underground operations and near-mine exploration.
- Oversee geological modelling and mineral resource estimation in a structurally complex, high-grade orogenic gold system, ensuring models are robust, auditable, and aligned with underground mine planning requirements.
- Ensure rapid integration of drilling results (grade control, infill, step-out, depth extensions, and regional targets) into resource models and short- to mediumterm mine plans.
- Design, review, and optimise drilling programs to improve ore definition, reconciliation, and mine life extension.
- Direct and support exploration activities across PNG, including drilling, mapping, sampling, logistics, and remote site operations.
- Act as a key technical advisor to mine operations, supporting production planning to maximise recovery, minimise dilution, and reduce geological risk.
- Establish and enforce high standards of data integrity, QA/QC, and database governance, suitable for PNG regulatory scrutiny and international reporting codes.

- Analyse and interpret geological and spatial data using Leapfrog (essential) and Deswik (highly regarded), while championing innovation in structural modelling and data integration.
- Mentor and develop PNG national geologists, supporting localisation, succession planning, and long-term capability building.
- Contribute to life-of-mine planning, feasibility studies, and corporate strategy, including evaluation of new PNG exploration opportunities.
- Promote and lead strong health, safety, environmental, and compliance performance across all geological and exploration activities.
- Deliver clear weekly, monthly, and quarterly reporting to site and corporate leadership.
