About The Position

Nevada Gold Mines is seeking a Mineralogist to support its Carlin operations. The role delivers mineralogical support to optimize gold processing performance, diagnose metallurgical issues, and provide technical guidance to operations and projects. The position works across exploration, mine geology, processing, environmental, and regional technical teams on geometallurgy and mine-to-mill initiatives. The posting describes Mineralogist I/II/III levels, with mentoring responsibilities and advanced experience requirements specified for the Senior Mineralogist (Mineralogist III).

Requirements

Bachelor of Science degree in Geology, Mineralogy, Metallurgical/Materials Engineering, or a related field.
Experience in a mineral processing or metallurgical laboratory, preferably in gold; 5+ years is required for Senior Mineralogist.
Ability to use common database, spreadsheet, and word-processing programs, including Excel and MS Word.
Hands-on experience with reflected light microscopy and at least one of XRD, SEM-EDS, or automated mineralogy.
Understanding of laboratory safety, chemical handling, and QA/QC in a formal quality environment.
Strong organizational skills and ability to manage competing priorities and work with minimal supervision in an operations-driven setting.
Excellent written and verbal communication skills, with the ability to collaborate across technical and operational teams.
Ability to work in an operations-focused team environment.
Proven safety record and ability to support the work group in achieving safety, environmental, and production goals.
Demonstrated ability to perform the essential functions of the position.

Nice To Haves

MSc or PhD in mineralogy, process mineralogy, or economic geology, preferred for Senior Mineralogist (Mineralogist III).
Experience with Labware.
Strong ore and process mineralogy skills in sulfide and gold systems, including textures, paragenesis, and alteration.
Track record of designing mineralogical programs that resolve metallurgical and operational problems.
Proficiency with standard office tools and mineralogy/imagery software for SEM-EDS, XRD, and automated mineralogy.
Advanced multi-technique expertise is expected for Senior Mineralogist.

Responsibilities

Characterize ore, plant, and exploration samples, focusing on gold occurrence, gangue, and deleterious minerals.
Diagnose refractory and double-refractory behaviors and connect mineralogy to grinding, flotation, leaching, POX, roasting, and tailings performance.
Troubleshoot plant issues 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).
Maintain data integrity and QA/QC, and follow laboratory methods, SOPs, and information systems.
Integrate mineralogical, assay, and metallurgical data to develop actionable conclusions and recommendations.
Prepare technical reports and presentations for metallurgists, geologists, engineers, and management.
Maintain and coordinate calibration and servicing of microscopes.
Collaborate with exploration, mine geology, processing, environmental, and regional technical teams on geometallurgy and mine-to-mill initiatives.
Promote strong safety, health, environmental, and community practices in the lab and field.
Mentor and coach technicians and junior professionals in mineralogy and laboratory practice at the Senior Mineralogist level.
Perform other duties as assigned.
