Professional Mining Engineering Services

Technically robust mining engineering studies and planning services aligned with JORC Code, NI 43-101 and internationally recognised reporting standards.

Mining Project Study Expertise

JYA provides technically robust mining engineering services designed to support Competent Person (CP) and Qualified Person (QP) sign-off with transparent, auditable and regulator-ready technical outputs across all project stages.

Our studies integrate geological models, geotechnical and hydrogeological inputs, mining methods, production schedules and modifying factors to generate defensible Resource to Reserve outcomes and investment-grade project evaluations.

  • Scoping, pre-feasibility and feasibility studies aligned with industry best practice
  • Pit optimisation, underground stope design, mine scheduling and production sequencing
  • CAPEX and OPEX estimation supported by first-principles cost modelling
  • Integrated financial models focused on NPV, IRR, sensitivities and downside scenarios
  • Resource to Reserve support using JORC and NI 43-101 compliant modifying factors
Mining engineering study and project planning

Our Study & Planning Services

Comprehensive mining engineering support from early-stage study work through to detailed planning, cost estimation and reserve conversion.

Scoping Studies

Early-stage technical and economic assessments that define project options, development pathways and key value drivers for informed decision-making.

Pre-Feasibility Studies (PFS)

Structured PFS work incorporating engineering definition, risk assessment and economic evaluation to support project advancement and technical confidence.

Feasibility Studies (FS / DFS)

Detailed feasibility and definitive feasibility studies developed to industry best practice with defensible assumptions, engineering detail and implementation readiness.

Mine Design & Planning

Pit optimisation, underground stope design, mine scheduling and production sequencing designed to maximise value while maintaining operational constraints and risk controls.

CAPEX / OPEX & Financial Modelling

Study-level cost estimation and integrated financial models built from first-principles methodologies and benchmarked against comparable mining operations.

Resource to Reserve Support

Technical support for Mineral Resource to Ore Reserve conversion, including dilution, recovery, metallurgy, infrastructure and economic modifying factors.

Mining Study Case Studies

Selected project study and mining engineering engagements that demonstrate practical, investment-focused technical outcomes for our clients.
