Reporting to the Senior Metallurgist, you’ll connect sampling, testing, and operating data with practical improvements in heap‑leach and SX/EW performance. This is a full‑time career position for an experienced professional, not an internship.

• Maintain accurate technical records and reports while following site safety and environmental requirements.

What you bring

• A bachelor’s degree in metallurgy, chemical engineering, materials science, or a related field.
• Three to seven years of relevant metallurgical or process engineering experience.
• Experience at an open‑pit, heap‑leach, SX/EW copper operation is strongly preferred.
• The ability to turn field observations and process data into practical recommendations.
• Strong communication and Excel skills, sound judgment, and a commitment to working safely.

Gunnison Copper offers competitive pay, professional growth, and the opportunity to contribute directly to the performance of a growing copper operation. Occasional night or weekend work may be required.
