About the role

You'll work closely with operations, technical services, and project development teams to ensure high metal recoveries, efficient reagent use, and safe, compliant plant operations.
This is a site-based role with regular exposure to both fieldwork and metallurgical analysis.

Optimize Metallurgical Processes - Monitor and improve metallurgical performance across heap leach pads, SX/EW plants, flotation circuits, and comminution areas (crushing/milling).
Identify bottlenecks, troubleshoot issues, and implement improvements to enhance throughput and recovery.
Design and Execute Test Program - Plan and supervise metallurgical testwork (e.g., column leach tests, flotation tests, grinding studies). Interpret results to support operational changes or project decisions.
Maintain accurate records of metallurgical balances, recoveries, and plant efficiency metrics.
Collaborate Across Teams - Work with operations, maintenance, and geology teams to integrate metallurgical insights into daily decision-making. Provide input to capital projects, equipment selection, and commissioning activities.
Skilled in metallurgical test design, data analysis, and performance optimization.
Design and Execute Test Program - Plan and supervise metallurgical testwork (e.g., column leach tests, flotation tests, grinding studies).
Interpret results to support operational changes or project decisions.
Collaborate Across Teams - Work with operations, maintenance, and geology teams to integrate metallurgical insights into daily decision-making.
Engineer Out Requirements, then Automate - We simplify, optimize, and then automate for scale.

3-7 years of experience in mineral processing, ideally with exposure to both hydrometallurgical and flotation circuits.
Strong understanding of heap leach dynamics, SX/EW systems, flotation chemistry, and comminution fundamentals.
Experience with metallurgical modeling and software tools such as METSIM, HSC, or similar process modeling software package

Expect a fast-paced, hands-on environment where your contributions directly influence production and growth.

Champion Safety and Compliance - Promote a strong safety culture and ensure that all metallurgical work aligns with environmental, health, and regulatory standards.
