Geologist

Why This Role

• The opportunity to build deep underground geology experience on one of the most significant copper deposits in North America
• Hands‑on exposure across the full resource evaluation workflow, from drilling and logging through modeling and interpretation
• Long‑term career opportunity on a major underground project near Superior, Arizona, backed by a global mining leader

As a Geologist, you are part of the team building the foundation of orebody knowledge that underpins all future mining decisions. You will work across surface and underground environments, collecting, validating, and interpreting high quality data in collaboration with drilling, core handling, and modeling teams. This is a rare opportunity to develop well‑rounded technical capability within a large, complex underground deposit.

We are currently hiring 2 Geologists to support this growing work.

• Always work safely and actively promote a strong safety culture during field, drilling, and underground activities
• Collect high quality geologic, geotechnical, and drilling related data in a timely and disciplined manner
• Manage daily core inflows including logging, photography, scanning preparation, geotechnical logging, and data QAQC
• Support and supervise drilling operations, reinforcing safe work practices and site standards
• Interpret drill core, core scanning outputs, and downhole geophysical data to support geologic understanding
• Conduct underground mapping, LIDAR scanning, and sampling during drift development and drilling activities
• Synthesize and communicate geologic interpretations to support updates to geologic and resource models
• Prepare daily and periodic reports on drilling progress, underground development, and data collection results
• Update and maintain geologic and drilling databases, reports, and diagrams
• Support focused technical projects that enhance understanding of structure, alteration, and mineralization
