The Mine Engineering Superintendent leads the mine engineering function and holds accountability for the integrity of the mine plan, from long-range life-of-mine sequencing through to the weekly plans the operating crews execute. The role owns the technical standards that govern planning, drill and blast design, ground control, and survey, and is responsible for ensuring those standards translate into safe, achievable, and cost-effective plans.

This is a leadership position rather than a senior individual contributor role. Success is measured by the performance of the department and the credibility of the engineering group across the site: whether the plan is issued on time and executed as designed, whether reconciliation is understood and acted on, whether costs are forecast accurately, and whether the next generation of engineers is being developed. The Superintendent is expected to spend meaningful time in the field and be hands on in the development of the engineering team as well as be the senior technical voice in operational decisions where ground conditions, sequencing, or equipment constraints put the plan at risk.

The Mine Engineering Superintendent reports to the Technical Services Manager and serves as a member of the site leadership team. Direct reports typically include Senior Mine Engineers, Drill and Blast Engineers, and Projects Engineers. The position works in close partnership with the Mine Operations Superintendents, Maintenance, Geology, Environmental, and Finance, and interfaces with corporate technical services on standards, studies, and reserve reporting.

• Exercise stop-work authority for any safety concern and hold the engineering team to that same standard in every design, review, and field inspection.
• Ensure engineering designs and work plans comply with federal and state mining regulations and with company safety standards before they are released to operations.
• Own the technical standards and safe operating procedures governing ground control and blasting and ensure they are reviewed and updated as conditions change.
• Participate in incident investigations where design, sequencing, or ground conditions are contributing factors, and drive the resulting corrective actions to closure.

• Own the integrity and accuracy of the mine plan across all horizons: life-of-mine, annual budget, quarterly forecast, and the short-range plans that drive daily execution.
• Approve designs, drill and blast packages, pit development sequencing, and ancillary/project designs prepared by the engineering team.
• Provide technical oversight of stockpile and waste dump management.
• Ensure the design basis for every plan is documented and defensible, including assumptions on dilution, recovery, cycle times, and equipment productivity.
• Direct the reconciliation program, comparing planned to actual tonnage, grade, dilution, and cycle time, and ensure findings feed forward into subsequent plans.
• Establish and maintain the standards, templates, and modeling conventions used across the group so that work is consistent, auditable, and transferable between engineers.

• Partner with the Mine Operations Superintendents to ensure the plan reflects real operational constraints — equipment availability, crew capability, and spatial conflicts — before it is issued to the field.
• Attend the weekly planning meetings, ensuring conflicts are identified and resolved, or that contingency plans are in place, before the plan is committed.
• Coordinate with Maintenance to align equipment availability and major component schedules with the mining sequence.
• Maintain a visible field presence, conducting regular inspections with operations leadership to confirm that work is being executed to design and to standard.
• Serve as the senior technical escalation point when ground conditions, equipment failures, or grade variability require the plan to be reworked in cycle.

• Lead the mine engineering contribution to the annual reserve and resource statement, including mine design, cut-off grade application, and mineable shape definition.
• Own the mining portion of the annual operating and capital budget, including plan development, consumables, and unit cost assumptions.
• Track performance against budget through the year and provide variance analysis and forecast revisions to site and corporate management.
• Evaluate alternative mining methods, equipment fleets, and sequencing options through trade-off studies, and present recommendations with supporting economics.

• Lead, coach, and develop the mine engineering team, setting clear expectations and holding people accountable for the quality and timeliness of their work.
• Build the technical team through structured mentoring, deliberate rotation across planning, drill and blast, and active succession planning for key roles.
• Conduct performance reviews, set development goals, and address performance concerns directly and fairly.
• Manage departmental resourcing, including workload balancing, recruitment, and the appropriate use of consultants and contract engineering support.
• Represent the engineering function to site leadership, corporate technical services, auditors, and external consultants, and present technical work clearly to non-technical audiences.

• Identify and lead business improvement initiatives that reduce mining cost per tonne, improve productivity, or reduce operational risk, and quantify the results delivered.
• Own the mine engineering reporting suite, including plan compliance, development and production performance, reconciliation, and unit cost indicators, and ensure reporting is accurate and issued on schedule.
• Ensure mine planning and design software, survey systems, and data management practices are current, well governed, and applied consistently across the team.
• Critique the cost and operating practice of each mining area and translate accepted improvements into updated standards and safe operating procedures.
• Contribute to site strategic planning and technical studies, including expansion, mine life extension, and closure planning inputs.

• Bachelor of Science in Mining Engineering from an accredited institution.
• A minimum of ten years of progressive mine engineering experience, including at least three years supervising technical staff.
• Professional Engineer registration or an equivalent professional designation.
• Prepare, review, and sign off on technical reports, feasibility studies, and mineral resource/reserve estimations as a certified Qualified Person.
• Demonstrated ownership of a mine plan at multiple horizons, from short-range planning through annual budget.
• Working knowledge of open pit mine planning and sequencing, ground control, drill and blast design, and reconciliation.
• Experience contributing to reserve estimation and annual budget preparation.
• Proficiency with mine planning and design software such as Deswik, Vulcan, or Maptek, and with the Microsoft Office suite.
• Working knowledge of federal and state mining and safety legislation and regulations.
• Proven ability to lead, mentor, and train technical professionals.
• Strong written and verbal communication skills, including the ability to present technical recommendations to senior management.
• Ability to work safely and to promote safe behavior in others.
• Sets high standards for self and others, builds trust, and takes accountability; approachable, reliable, and team oriented.

• Prior accountability for a departmental operating and capital budget.
• Experience leading or contributing to technical studies such as prefeasibility, feasibility, or expansion studies.
• Experience implementing or upgrading mine planning software, scheduling systems, or engineering data management platforms.
• Formal leadership or people management training.

The competencies below distinguish this role from the senior engineering positions that report into it. Candidates are assessed against all six.

Designs and sequences with risk in mind and is visible in the field confirming that the plan is being executed safely.

Knows which assumptions matter, challenges numbers that do not reconcile, and can defend the design basis under scrutiny.

Holds the planning cycle to its dates and its standards, so operations receive a plan it can trust and execute.

Earns credibility with operations, maintenance, and geology so the plan is owned by the site rather than issued to it.

Grows engineers deliberately, delegates real accountability, and builds a bench capable of stepping up.

Understands the cost and value consequences of technical decisions and presents options with the economics attached.

• Registration as a certified Qualified Person.
• The mine plan is issued on schedule at every horizon, and plan compliance is measured, reported, and trending upward.
• Reconciliation between plan and actual is routine and well understood and is used to improve the next plan rather than to explain the last one.
• Operations, maintenance, and geology describe the engineering group as a partner in execution rather than a source of drawings.

• Competitive AIP (Annual Incentive Plan)
• Full benefits on day 1 (medical, vision, dental, employee assistance program, Teladoc service)
• 6% dollar-for-dollar employer match to 401k or Roth, immediate vesting
• Bus service from Lovelock, Fallon, and Winnemucca
• Travel pay for those outside of bus service
• Complimentary health clinic in Lovelock for benefit-enrolled employees and their dependents, providing convenient access to quality care at no additional cost
