In the modern mining industry, project success depends on credibility, technical accuracy, and global compliance. JORC and NI 43-101 standards provide a structured framework to ensure that mineral resources and reserves are reported transparently and supported by sound technical and economic analysis.
These internationally accepted codes form the foundation for investor confidence, regulatory approval, and project financing.
What Are JORC and NI 43-101?
- JORC Code (Australasia): Governs public reporting of exploration results, mineral resources, and ore reserves through a Competent Person.
- NI 43-101 (Canada): A regulatory standard requiring technical disclosures to be validated by a Qualified Person (QP).
Both ensure that mining projects are presented with accuracy, consistency, and accountability, making them globally acceptable.
Key Components of a Feasibility Study
A JORC/NI 43-101 compliant feasibility study is a complete blueprint for mine development, covering:
- Geology & Resources: Resource estimation and reserve conversion
- Mining Plan: Pit design, scheduling, and production strategy
- Process Design: Metallurgical test work and flowsheet development
- Infrastructure: Power, water, plant layout, and logistics
- Environmental & ESG: Tailings, water management, and compliance
- Financials: CAPEX, OPEX, NPV, IRR, and risk analysis
The objective is to demonstrate that the project is technically viable and economically mineable.
Study Progression
Mining projects advance through structured stages:
- Scoping Study (PEA): Concept level
- Pre-Feasibility (PFS): Option selection
- Feasibility Study (FS): Investment decision
The Feasibility Study provides the highest level of confidence for project execution and funding.
Focus on Sustainability
Modern feasibility studies integrate sustainability from the start:
- Efficient water use and recycling
- Safe tailings and cyanide management
- Energy optimization and reduced environmental impact
- Responsible mining aligned with ESG principles
Why Compliance Matters
JORC and NI 43-101 compliance ensures:
- Strong investor confidence
- Easier access to global funding
- Reduced technical and financial risks
- A clear path from resource to production
