Job description

COMPANY DESCRIPTION

G Mining Ventures is a gold producer with a growing portfolio of assets at different stages of development across the Americas. Over the past two years, the Corporation has evolved from a single-asset developer into an operator and builder, supported by operating cash flow and a pipeline of funded growth opportunities.

JOB SUMMARY

Reporting to the Vice President, Geology & Resources, the Principal Mining Engineer provides senior technical leadership in mine planning, optimization, and evaluation across GMIN’s gold operations, development projects, and growth opportunities, with a focus on South America. The role guides integrated Life of Mine planning, reviews operating performance, and contributes mining expertise to Mineral Reserve estimates, technical studies, and acquisition evaluations.

Working closely with site Technical Services, Geology & Resources, Operations, Finance, and Project teams, the incumbent challenges planning assumptions, evaluates risks and opportunities, and recommends practical improvements that support safe operations, reliable production forecasts, and long-term asset value. The role also strengthens planning standards and develops technical capability across the portfolio.

WORKING CONDITIONS

The Principal Mining Engineer based at G Mining Ventures’ office in Brossard, Quebec will be an office-based role, offering flexibility for remote work and requiring availability for international travel to GMIN operations and projects.

KEY RESPONSIBILITIES

Mine Planning and Technical Leadership

• Provide senior technical guidance for mine design and integrated Life of Mine planning, ensuring alignment with short- and medium-term plans, annual budgets, and Mineral Resource and Mineral Reserve models.
• Review and challenge mine designs, schedules, and key assumptions, including mining rates, sequencing, equipment productivity, dilution, mining recovery, and geotechnical constraints.
• Work with relevant specialists to incorporate processing capacity, metallurgical recovery, infrastructure, water management, environmental and permitting requirements, and closure considerations into achievable mine plans.
• Identify material planning risks and recommend mitigation measures, incorporating health, safety, and responsible mining practices into engineering decisions.

Strategic Optimization and Asset Evaluation

• Develop and review scenarios and trade-off studies covering pit optimization, production rates, cut-off grade strategies, stockpile management, haulage, and equipment selection.
• Evaluate operating costs, capital requirements, and sensitivities with Finance and technical teams to recommend options that improve asset economics, manage risk, or extend mine life.
• Support technical due diligence for acquisitions and growth opportunities, including assessment of mine plans, cost assumptions, execution risks, and opportunities to incorporate resource extensions into future plans.

Mineral Reserves and Technical Studies

• Contribute mining engineering inputs to Mineral Reserve estimates in collaboration with Geology & Resources and other technical specialists.
• Develop and review mining modifying factors and economic assumptions, including dilution, mining recovery, cut-off grades, mine design criteria, and cost parameters; support evaluation of Mineral Resource conversion opportunities.
• Contribute to and review the mining components of scoping studies, preliminary economic assessments (PEAs), prefeasibility studies (PFSs), feasibility studies (FSs), and NI 43-101 technical reports, as applicable.
• Coordinate mining study inputs from site teams and external consultants, reviewing deliverables for technical quality, consistency of assumptions, and appropriate supporting documentation.

Operational Performance Forecasting

• Review mine performance against budgets, forecasts, and Life of Mine plans with site teams to understand material variances and recommend corrective actions.
• Evaluate planned versus actual tonnes, grades, dilution, mining recovery, productivity, and costs, using reconciliation results to improve planning assumptions and forecast reliability.
• Provide mining inputs to rolling production forecasts, annual business plans, and corporate production guidance, maintaining consistency with long-term objectives and clearly communicating material risks.

Technical Governance

• Develop and promote consistent corporate mine planning standards, review processes, and methodologies, with appropriate application of NI 43-101 and CIM standards and guidelines.
• Maintain traceable assumptions, model and schedule versions, and records of technical decisions; use relevant operating benchmarks to support planning inputs.
• Present technical findings and recommendations to senior management, explaining the implications for production, costs, risk, and asset value.

Site Support and Technical Development

• Partner with site Technical Services teams to improve planning workflows and the effective use of mine planning and optimization software.
• Coach and mentor mining engineers and facilitate technical reviews and knowledge sharing across operations and projects.
• Evaluate relevant technologies and industry practices and support practical improvements suited to each asset’s operating conditions.

REQUIREMENTS

Educational and Professional Designation

• Bachelor’s degree in Mining Engineering or a related engineering discipline.
• Professional Engineer designation, or eligibility for professional registration, is considered an asset.

Experience

• At least 10 years of progressive mining engineering experience, including significant responsibility for mine planning and technical studies and demonstrated senior technical leadership.
• Extensive open-pit mine planning experience, supported by practical exposure to mining operations. Underground mining experience is considered an asset.
• Demonstrated experience developing and reviewing Life of Mine plans, mine designs, production schedules, budgets, and planning scenarios.
• Experience contributing mining inputs to Mineral Reserve estimates and preparing or reviewing PFSs, FSs, or comparable technical studies.
• Experience in gold operations or development projects is strongly preferred. Experience in technical due diligence is considered an asset.
• Experience working with site teams in remote, multicultural mining environments is preferred, particularly in South America.

Technical Knowledge and Skills

• Strong knowledge of open-pit design, optimization, scheduling, fleet productivity, haulage, dilution, and mining recovery, including the effects of geotechnical and processing constraints on mine plans.
• Strong understanding of mine economics, operating and capital costs, cut-off grade strategies, scenario analysis, and sensitivity analysis.
• Working knowledge of Mineral Resource and Mineral Reserve classification, mining modifying factors, NI 43-101, and CIM Definition Standards and Best Practice Guidelines.
• Advanced proficiency with recognized mine planning and optimization software, such as Deswik, Datamine, Whittle, MineSched, or equivalent platforms.
• Strong capability in spreadsheet analysis and the interpretation of operational and reconciliation data.

Leadership and Professional Competencies

• Sound technical judgment and analytical skills, with the ability to challenge assumptions independently and turn complex findings into clear, practical recommendations.
• Strong communication and collaboration skills, with the ability to influence decisions across disciplines and provide technical leadership without direct reporting authority.
