NI 43-101 Technical Report: Standards & Best Practices

The NI 43-101 technical report governs mineral project disclosure for Canadian reporting issuers, but is widely adopted as the gold standard internationally, including for operations in Western Australia such as St Ives. This regulatory framework enforces rigorous standards for data integrity, qualified personnel, methodology disclosure, and error checking.

• ✔ Personnel Qualification: All technical statements must be underpinned by the expertise of a Qualified Person (QP), whose credentials, independence, and site familiarity must be declared.
• ⚡ Data Validation: From sample collection to assay and modelling, every data source used in resource and reserve estimation must be cross-checked, documented, and reproducible.
• 📄 Reporting Transparency: The report requires full disclosure of methods, model assumptions, parameters, and economic factors. Sensitivity analyses are provided to show impacts of fluctuating metal prices, costs, and exchange rates.
• ⚠️ Delineation of Uncertainties: Uncertainties—whether geological, metallurgical, operational, or economic—are clearly described, ensuring risks are made transparent to all stakeholders.

These foundational elements are evident throughout the St Ives Gold Mine technical report, enhancing stakeholder confidence and aligning with global best practices.

Geology & Resource Estimation at St Ives Gold Mine

The geological framework of St Ives is dominated by brittle, structurally-controlled gold systems. Primary ore is contained within steeply dipping, quartz-carbonate-sulfide veins and lodes hosted in Archaean greenstone sequences. Ore shoots are typically disseminated within fracture-controlled host rocks, requiring precision in geological interpretation and resource estimation for reliable economic planning.

Resource estimation at St Ives is grounded in:

• 🟦 High-quality drill data—including precise collar surveys, downhole geophysical measurements, and laboratory assay data
• 🟩 3D geological modelling—integrating lithology, alteration zones, mineralization trends, and structural controls
• 🟧 Geostatistical grade interpolation—using kriging and other methods with domain-specific parameters, factoring in spatial continuity, anisotropy, and grade domaining
• 🟥 Cut-off grades and economic parameters—tuned for optimal ore recovery while ensuring acceptable levels of dilution and loss

Each stage in this process is rigorously documented, enabling expert review and compliance with NI 43-101 report requirements.

Block Model Design and Ore Data Integration

Accurate ore data capture and block modelling underpin defensible resource and reserve statements in the St Ives Gold Mine technical report. The methodology integrates multi-source data:

1. Precise drill collar and downhole surveys for spatial accuracy
2. Comprehensive assay data—detailing gold grades, mineralization width, and ancillary element concentrations
3. Geophysical logs and digital core imagery to support lithological and alteration domaining
4. 3D model construction—using wireframes and block models updated with each new drill campaign
5. Automated geostatistical interpolation—kriging, inverse distance, or nearest neighbor, depending on spatial data density and continuity requirements

Cut-off grade calculation, dilution and ore loss factors, and economic filter parameters are adjusted in response to new data—the process is inherently dynamic and subject to routine validation and sensitivity analyses as demanded by the 43 101 technical report standards.

“Advanced mining methods at St Ives achieve ore recovery rates exceeding 90%, as documented in the latest technical report.”

Mining Methods, Design & Sustainable Stewardship

Mining at St Ives prioritizes a balance of safe, productive extraction with strong environmental and social stewardship. The 43-101 technical report details an integrated approach to mining method selection, equipment use, and the technical design of stope geometries, pillars, and backfill strategies.

Commonly used mining methods include:

• Sublevel open stoping for steep, continuous ore zones with reliable ground conditions
• Cut-and-fill for variable or narrow lodes, enabling selective extraction and reduced dilution

Each method is evaluated for ore recovery, dilution, safety, and environmental considerations. Stopes and pillars are strategically designed for ground support, mining sequence control, and progressive backfill to reduce geotechnical risk and control subsidence.

💡 Sustainable Mining Design Principles

• Efficient Ore Transfer: Schedule-driven ore/waste routing, harmonized with equipment and ventilation plans
• Worker Health & Safety: Dust suppression, noise reduction, and real-time air quality monitoring
• Rehabilitation: Progressive closure methodology, landform reshaping, and re-vegetation
• Biodiversity Alignment: Mine design considers local species, habitats, and post-closure land use
• Regulatory Integration: Continuous engagement with local and regional regulators for ongoing compliance

Processing, Metallurgical Recoveries & Production Rates

Gold processing at St Ives is described with full transparency, detailing each stage from ore comminution to concentrate or doré production. The technical report outlines:

• Crushing and grinding circuits optimized for ore hardness and throughput requirements
• Gravity separation and flotation as primary beneficiation mechanisms
• Leaching (where applicable) for recovery of refractory gold
• Systematic testwork reporting on recovery rates, impurity profiles, and tailings characterization

Recovery models are subjected to routine sensitivity analyses—testing for ore variability by lithology, sulfide content, and grade. Average recovery rates above 90% are achieved due to both process optimization and strict adherence to metallurgical best practices.

Environmental, Social, and Governance Considerations

The St Ives technical report gives equal importance to environmental, social, and governance (ESG) practices as it does to geological and processing metrics. ESG compliance is integrated through:

• 🌍 Baseline and ongoing environmental monitoring including water use, soil stability, and ecosystem health
• 🧭 Tailings management: Detailed containment strategies, periodic dam stability checks, and downstream impact analyses
• 👥 Community engagement: Structured consultation with local and indigenous groups, benefit-sharing protocols, and grievance redressal mechanisms
• 🛡️ Worker health and safety: Mandatory reporting of lost-time injuries, real-time emergency response systems, and ongoing training programs
• 🔗 Regulatory compliance: Continuous reporting to government and environmental agencies, with rapid adaptation to evolving standards

Strong ESG performance is highlighted as a cornerstone of modern mining practice—creating sustained social license, reducing operational risk, and supporting broader industrial and regional economies.
