About the role

We are looking for a Geologist - Logging to collect, interpret and deliver high-quality geological and geotechnical data that strengthens resource knowledge and supports safe, informed decisions across Rio Tinto Kennecott. Working closely with mapping and modelling geologists, geotechnical engineers, metallurgists and drill contractors, you’ll turn drill core, chip, survey and geophysical information into practical geological interpretations for current open-pit investigations and future open-pit and underground development.

This is a great opportunity for someone who enjoys hands-on geology, careful data stewardship and collaborative problem solving, and wants to deepen their technical capability in a major mining operation.

Reporting to the Superintendent, Logging & Core Shed and working in a collaborative, multidisciplinary geology environment within the Mine planning team, you will

• Log and sample diamond drill core and chips, capturing rock type, structure, alteration, mineralogy and geotechnical information to required standards.

• Interpret geological and geotechnical data to support resource understanding, mine planning, expansion studies and geological models.

• Review and interpret down-hole surveys and borehole geophysical data, including acoustic televiewer logging, to improve subsurface understanding.

• Maintain geological and geotechnical data quality through effective quality assurance and quality control, chain-of-custody practices and complete documentation.

• Integrate multiple data streams into clear, practical interpretations and provide timely information to modelling geologists and geotechnical engineers.

• Coordinate with drill contractors and technical stakeholders, providing geological recommendations that support safe and effective daily drilling operations.

• Use geological software and data systems to compile, validate, analyse and communicate technical information.
