The role is based at the company's Denver headquarters, with approximately 25% travel to operating and exploration assets.

This is a technically focused position with exposure to a broad range of exploration and resource development activities, including:

• Leading the generation and evaluation of brownfield targets across mine, near-mine and regional environments
• Integrating geological, geochemical, geophysical and drilling datasets to develop and refine exploration hypotheses
• Developing and continuously refining geological interpretations and 3D models to support target advancement
• Leading litho-structural mapping and field investigations
• Providing technical oversight and peer review of drill programs across the portfolio
• Reviewing and prioritising exploration targets and presenting technical recommendations to senior stakeholders
• Leading the consolidation, maintenance and continuous improvement of geological datasets and GIS platforms across the portfolio
• Evaluating and applying new exploration techniques, technologies and datasets to improve targeting effectiveness
• Working closely with site geology, resource geology, mine geology and technical services teams to improve orebody understanding and align exploration activities with business priorities
• Providing technical leadership, guidance and mentorship to geologists and technicians

What they're looking for:

• Strong experience in litho-structural mapping
• Significant experience in brownfield exploration and target generation, ideally within precious metals environments
• Experience working in orogenic, epithermal and/or Carlin gold systems
• Strong GIS capability, with ArcGIS Pro experience an advantage
• Proficiency with Leapfrog Geo or equivalent 3D modelling software
• Strong geological interpretation and exploration targeting capability
• Proven ability to communicate technical interpretations and recommendations to both technical and non-technical stakeholders, including senior leadership
• A collaborative approach and strong commitment to HSEC standards
• Willingness to travel approximately 25% across the company's operating and exploration assets throughout North and South America

This is an exciting opportunity to take on a portfolio-wide technical leadership role, working across exploration targets and producing operations while contributing directly to resource discovery and growth.
