· Execute aggregate gradation and physical property tests to meet plant specifications.

· Measure moisture content, density, and mineral composition for operational reporting.

· Operate, calibrate, and maintain laboratory equipment, including spectrometers, flotation cells, sieves, scales, and moisture analyzers.

Data Management & Reporting

· Record, analyze, and report test results with precision and accuracy.

· Generate daily and weekly laboratory reports for mine operations and plant management.

· Competence in technical reporting, data documentation, and communication with operations staff.

· Physically capable of handling heavy samples and working in industrial environments.

Preferred:

· Experience with froth flotation, tailings analysis, and iron ore beneficiation.

· Background in precious metals assay, rare earth testing, or aggregate plant operations.

· MSHA Part 48 certification or willingness to obtain upon hire.

Physical Demands/Environmental Factors
