• Build in-demand project controls and SAP expertise in a structured, well-supported environment that strengthens your long-term career options in mining and heavy industry
• Play a key role in a high-profile underground project, where your work directly impacts cost performance, decision-making, and overall project success

Build your career with a leading global mining organization while staying close to home in the Copper Triangle. As a Cost Control Administrator at Resolution Copper, you will play a key role in supporting cost discipline across operations and maintenance, helping ensure a world-class underground project is delivered efficiently and responsibly. This role is ideal for someone who enjoys working with data, solving problems, and partnering with multiple teams to drive outcomes that matter.

You will gain exposure to complex project environments, advanced systems, and cross-functional teams, all while developing highly transferable skills in cost control, procurement, and financial coordination within a technically advanced mining operation.

You collaborate with project managers and finance partners, resolve questions quickly, and close out the day knowing the project is financially on track and well-supported.

Some days bring complexity. You may encounter delayed invoices, mismatched cost codes, or incomplete contractor submissions that require investigation. You work across teams to resolve discrepancies, clarify details, and keep financial tracking accurate.

Where you will be working

You will be joining Resolution Copper at a pivotal moment in the project’s history. With the Resolution Copper Land Exchange now complete, the project is advancing its next phase of technical work, community engagement, and state permitting activities.

Resolution Copper has the potential to supply nearly 25% of total U.S. copper demand and generate several thousand direct and indirect jobs in the Pioneer Mining District of Arizona, delivering an economic value of several billion dollars over the life of the mine. The project will rely on block caving, a proven underground mining method that uses gravity to extract ore from a deposit located more than 2,000 meters below the surface. This technique is the most viable way to safely and efficiently recover the resource.

As development continues, Resolution Copper will expand its underground operations, conduct extensive drilling and orebody characterization, and maintain both the permitting process and ongoing public engagement with Native American tribes, local communities, and stakeholders.

The Resolution Copper project is vital to securing America’s energy future, infrastructure needs, and national defense by providing a domestic supply of copper and other critical minerals. Once operational, it has the potential to become one of the largest copper mines in the United States, contribute approximately $1 billion annually to Arizona’s economy, and create thousands of local jobs in a region with more than a century‑long mining heritage.
