JOB DESCRIPTION

Would you like to have a career with a collaborative, diverse, and dynamic mining company? We have an exciting opportunity for you!

We are seeking a Mineralogist to join our team at our Carlin operations. This individual will deliver high‑impact mineralogical support to optimize gold processing performance, diagnose metallurgical issues, and provide clear technical guidance to operations and projects.

At Nevada Gold Mines, our vision is to be the world’s most valued gold mining business by finding, developing, and operating the best assets with the best people. We are committed to a safe work environment sending every person home safe and healthy every day and leaving a sustainable legacy on our host communities.

• Characterize ore, plant, and exploration samples, focusing on gold occurrence, gangue, and deleterious minerals.
• Diagnose refractory and double‑refractory behaviors and link mineralogy to grinding, flotation, leaching, POX, roasting, and tailings performance.
• Provide rapid plant troubleshooting using mineralogical data and recommend practical process adjustments.
• Evaluate new ore bodies and blends, defining mineralogical response to POX, roasting, and cyanidation test work.
• Design and oversee representative sample preparation for routine and investigative mineralogy programs.
• Develop and apply mineral analysis methods using reflected light microscopy, XRD, SEM‑EDS, and automated mineralogy (MLA/QEMSCAN/TIMA).
• Enforce data integrity, QA/QC, and adherence to laboratory methods, SOPs, and information systems.
• Integrate mineralogical, assay, and metallurgical data to produce actionable conclusions and recommendations.
• Prepare concise technical reports and presentations for metallurgists, geologists, engineers, and management.
• Maintain and coordinate calibration and servicing of microscopes.
• Collaborate closely with exploration, mine geology, processing, environmental, and regional technical teams on geometallurgy and mine‑to‑mill initiatives.
• Lead and model strong safety, health, environmental, and community practices in the lab and field.
• Mentor and coach technicians and junior professionals in mineralogy and laboratory practice (Senior Mineralogist).
• Perform other duties as assigned.

• Bachelor of Science degree in Geology, Mineralogy, Metallurgical/Materials Engineering, or related field required; MSc/PhD in mineralogy, process mineralogy, or economic geology preferred for Senior Mineralogist (Mineralogist III).
• Experience in a mineral processing or metallurgical laboratory, preferably in gold; 5+ years for Senior Mineralogist required.
• Ability to work with common database, spreadsheet and word processing programs (Excel and MS Word) required.
• Experience with Labware preferred.
• Proven hands‑on experience with reflected light microscopy and at least one of XRD, SEM‑EDS, or automated mineralogy; advanced multi‑technique expertise expected for Senior Mineralogist required.
• Strong ore and process mineralogy skills in sulfide and gold systems, including textures, par agenesis, and alteration preferred.
• Track record of designing mineralogical programs that resolve metallurgical and operational problems preferred.
• Proficient with standard office tools and mineralogy/imagery software for SEM‑EDS, XRD, and automated mineralogy preferred.
• Solid understanding of lab safety, chemical handling, and QA/QC in a formal quality environment required.
• Strong organizational skills, able to manage competing priorities and work with minimal supervision in an operations‑driven setting required.
• Excellent written and verbal communication, able to influence and collaborate across technical and operational teams required.
• Ability to work in an operations focused…
