About Jerritt Canyon

The Jerritt Canyon deposit was discovered in 1972, with first gold production from the property occurring in 1981. The Jerritt Canyon property includes 30,821 hectares of mining claims in Nevada. First Majestic acquired the Jerritt Canyon Gold Mine from Sprott Mining Inc. on April 30, 2021. In May 2023, operations were suspended to prioritize exploration and technical studies. Jerritt Canyon is now entering a new phase of evaluation and planning, requiring reliable technical support to advance work associated with a potential future restart of operations.

The Communications Systems Specialist is responsible for the design, implementation, maintenance, troubleshooting, and continuous improvement of mission‑critical communications systems that support mining operations. This role helps ensure the reliability, availability, and performance of two‑way radio networks, dispatch systems, private LTE infrastructure, microwave and wireless backhaul, and related communications equipment used across surface and underground mining environments.

Working closely with Mine Operations, IT, Maintenance, Safety, Security, and Engineering teams, the Communications Systems Specialist provides technical support and leadership for communications infrastructure, supports operational technology (OT) initiatives, and helps ensure communications systems meet operational, safety, and regulatory requirements.

• Install, configure, program, maintain, and troubleshoot portable, mobile, base‑station, digital, analog, and LTE‑enabled radio systems.
• Maintain repeaters, duplexers, multicouplers, combiners, antennas, feedlines, RF distribution equipment, grounding systems, and related radio infrastructure.
• Perform radio fleet management, firmware updates, codeplug maintenance, talkgroup/channel configuration, and subscriber provisioning.
• Conduct RF coverage testing, drive/walk testing, signal‑strength validation, and coverage gap analysis across surface and underground work areas.
• Troubleshoot interference, signal degradation, poor audio quality, failed equipment, antenna issues, cabling faults, and network connectivity problems.
• Support dispatch radio consoles, recording systems, emergency communication channels, paging/alerting systems, and radio interoperability requirements.
• Manage daily operations of the communications/radio shop, including work prioritization, service requests, repairs, and field support coordination.
• Maintain inventory of radios, batteries, chargers, antennas, accessories, spare parts, programming cables, test equipment, and critical communications supplies.
• Calibrate, repair, bench test, and document communications equipment using approved test equipment and standard operating procedures.
• Maintain accurate documentation, including radio asset records, codeplug versions, frequency/talkgroup assignments, repair history, maintenance schedules, wiring diagrams, and site configuration records.
• Coordinate vendor support, warranty repairs, contractor activities, licensing support, and equipment lifecycle planning for communication systems.
• Support deployment, optimization, and maintenance of private LTE infrastructure supporting mining operations and operational technology applications.
• Configure and support LTE base stations, EPC/core components, SIM management, subscriber provisioning, and device onboarding processes.
• Monitor LTE and radio network performance, analyze alarms, review system logs, and resolve connectivity or performance issues.
• Coordinate LTE and radio integration with dispatch, fleet management, telemetry, safety systems, security systems, and other operational technologies.
• Perform communications network performance analysis, capacity planning, and reliability improvement recommendations.
• Assist with migration planning from legacy radio systems to LTE‑enabled or hybrid communication solutions.
• Support microwave, wireless backhaul, fiber optic, Ethernet, and IP‑based communications infrastructure associated with site communications reliability.
• Monitor system health using network management, radio management, and monitoring tools; elevate issues as needed to…
