We are looking to expand our team at our metallurgical testing lab in Fort Collins, Colorado. As our new Metallurgical Technician , you will play an important role on a team whose work is essential to achieving this goal.

Role

In this position you will support metallurgical and analytical testing programs by preparing, processing, and analyzing ore samples in a laboratory and field environment. The role requires hands-on work with crushers, pulverizers, sample splitters, and leaching equipment. Ideally, you will have experience handling geological and metallurgical samples, working safely in a dusty and physical environment, and following detailed SOPs to ensure quality data generation. This position directly supports metallurgists, laboratory managers, and field test supervisors in metallurgical process evaluation, ore characterization, and leach optimization programs.

Responsibilities

Sample Preparation and Ore Handling (50%)

• Receive, log, and label incoming ore and metallurgical samples from clients, field projects, or mine sites.
• Use jaw crushers, roll crushers, and cone crushers to reduce rock specimens to specified particle sizes for analysis.
• Operate ring and puck pulverizers, ball mills, or disk mills to further homogenize samples to fine powder (e.g., -150 µm or finer).
• Perform riffle and rotary sample splitting to obtain representative sub-samples for assay, leaching, or metallurgical testing.
• Combine, bag, and inventory composite samples accurately according to test instructions or client specifications.
• Routinely lift, shovel, and handle bulk material (up to 50 lbs) for composites, agglomeration batches, or column leach charges.
• Maintain clean and calibrated equipment, including dust collection systems, crushers, and pulverizers to prevent contamination.

Testing Support (30%)

• Assist in setting up, charging, and operating bench and pilot-scale leach tests (bottle rolls, column tests, vat leaching, etc.).
• Collect liquid and solids samples during leach cycles at designated intervals for solution assay, pH, dissolved oxygen, and cyanide concentration.
• Prepare and weigh reagents (cyanide, lime, acids, etc.) for solution chemistry and cyanide destruction tests.

Laboratory Operations (10%)

• Clean and maintain work areas and ensure safe handling of hazardous materials per MSDS and safety procedures.
• Follow Quality Control/Quality Assurance (QC/QA) protocols for duplicate samples, blanks, and standards.
• Assist in data entry for sample tracking, assay reporting, or metallurgical balances.

Safety and Compliance (10%)

• Follow safety practices and wear proper PPE when working in dusty, noisy, or chemical environments.
• Comply with OSHA standards, lockout/tagout procedures, and industrial hygiene protocols.
