Job Title: Deputy Geology Manager

• Location: Port Moresby, Papua New Guinea
• Industry: Mining and Resources; Geology
• Work Type: In-office; Full-time

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, critical to the delivery of geological integrity, resource growth, and mine life extension. The successful candidate will provide hands-on geological leadership across mine geology, resource modelling, and exploration, while mentoring teams and acting as a trusted technical advisor to operations and senior management.

Key Responsibilities:

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.
• Prepare, review, and contribute to JORC and NI 43-101 compliant technical reports, working with independent consultants and auditors.
• Act as or support the Competent Person / Qualified Person for exploration results and mineral resource statements, as appropriate.
• Lead and participate in technical reviews, audits, and engagements with the PNG Mineral Resources Authority (MRA).
• 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.

About You

You will bring:

• A degree in Geology (Honours preferred); postgraduate qualifications advantageous.
• 15+ years’ experience in underground gold geology, with strong exposure to structurally complex orogenic systems.
• Demonstrated expertise in Leapfrog (advanced level essential); Deswik experience highly desirable.
• Proven experience in mineral resource estimation, underground grade control, and near-mine exploration.
• Strong understanding of JORC and NI 43-101 reporting standards.
• Experience operating in PNG or similar remote, logistically challenging jurisdictions is highly regarded.
• A collaborative leadership style with the ability to mentor, influence, and build high-performing technical teams.
• High personal standards for safety, integrity, and professional accountability.

SENIOR MINE GEOLOGIST - in Port Moresby, Papua New Guinea; Industry: Mining and Resources; Geology ; Work Type: On-Site; Full-time

 

Job Title: Senior Mine Geologist

• Location: Port Moresby, Papua New Guinea
• Industry: Mining and Resources; Geology
• Work Type: On-Site; Full-time

Overview:

We are seeking an experienced Senior Mine Geologist to join the geology team at a high-grade underground gold operation in Papua New Guinea. This is a key site-based role supporting safe, efficient, and profitable underground mining through high-quality geological interpretation, grade control, and short-term mine planning support. The role works closely with the Geology Manager and Deputy Geology Manager and interfaces daily with mine operations, planning, and engineering teams.

Key Responsibilities:

The Senior Mine Geologist will be responsible for:

• Delivering accurate and timely underground mine geology and grade control, ensuring ore boundaries, structures, and mineralisation are clearly defined for production.
• Building, updating, and refining 3D geological and structural models using Leapfrog (essential) to support grade control, short-term planning, and reconciliation.
• Integrating diamond drilling, face mapping, channel sampling, and underground observations into geological models in near real time.
• Supporting the design and execution of grade control, infill, and short-range drilling programs, in collaboration with mine planning and drilling teams.
• Interpreting structurally controlled, high-grade vein systems, including identification of ore shoots, plunge controls, and structural offsets.
• Assisting with mine-to-model and mine-to-mill reconciliation, identifying geological drivers of variance and recommending improvements.
• Maintaining high standards of sampling quality, QA/QC, and geological data integrity, consistent with PNG regulatory and company requirements.
• Preparing and reviewing geological inputs for weekly and monthly mine plans.
• Providing geological guidance to operations to maximise recovery, minimise dilution, and manage geological risk.
• Using Deswik (highly regarded) for short-term mine design review, reconciliation, and alignment between geology and planning.
• Supporting resource development activities through interpretation of underground drilling and model updates.
• Mentoring and supervising junior and national geologists, contributing to skills transfer and localisation objectives.
• Ensuring all geological activities comply with PNG statutory, safety, and environmental requirements.
• Contributing to regular reporting on geology performance, reconciliation, and forward work programs.

About You

You will ideally bring:

• A degree in Geology (Honours preferred).
• 8–12+ years’ experience in underground gold mining, ideally within structurally complex, high-grade vein systems.
• Advanced, practical experience with Leapfrog for structural and orebody modelling.
• Working knowledge of Deswik for mine planning and reconciliation (desirable but not essential).
• Strong understanding of underground grade control, face mapping, sampling techniques, and reconciliation workflows.
• Strong communication skills and the ability to work collaboratively with mine operations and planning teams.
• A safety-first mindset and high professional standards.
