How is the Solid Mineral Resource Estimation Process Conducted?
Precise and verified resource estimations are conducted in compliance with international reporting codes (CRIRSCO: JORC, NI 43-101, SAMREC, KAZRC).
The process encompasses 4 core stages:
- Data Aggregation and Synthesis — assembly and validation of geological mapping, drilling logs, geophysical survey records, and laboratory assay results to build an integrated deposit framework;
- Quantity and Grade Estimation — spatial analysis and geostatistical modeling of grade distribution within mineralized envelopes using advanced digital 3D block models;
- International Resource Classification — categorization of mineral assets into Inferred, Indicated, and Measured Resources based on geological confidence and QA/QC compliance;
- Technical Reporting and Strategic Recommendations — compilation of audit-ready technical reports containing resource estimates, classification metrics, and risk-mitigated strategies for asset progression.
The Result — Clients receive a comprehensive Technical Report detailing all resource estimation parameters, formal resource categories, and strategic recommendations for subsequent mine planning and development phases.

The Importance of Mineral Resource Estimation
Mineral resource estimation serves as a pivotal instrument for executive decision-making and capital allocation in subsoil management. It establishes the baseline for downstream exploration strategy, defines the economic viability of deposit development, and instills institutional investor confidence.
Raw assay records and drilling logs alone are insufficient — precise data synthesis, spatial interpolation, and robust 3D geological modeling are required to substantiate resource tonnages and grades. Errors at this stage risk inflated asset valuations, capital misallocation, and flawed investment frameworks.
GeoJet Group executes mineral resource estimations in full alignment with international standards (CRIRSCO: JORC, NI 43-101, SAMREC), securing global reporting recognition and absolute audit transparency.

Approach and Methodology
Mineral resource estimation is executed through a structured, multi-phase framework designed to deliver objective, verifiable, and audit-ready results.
1. Data Aggregation, Audit, and Synthesis
The initial stage focuses on the collection and thorough auditing of geological maps, drilling logs, geophysical survey data, and laboratory assay records. Key emphasis is placed on Quality Assurance / Quality Control (QA/QC) verification — assessing sampling methodologies, assay laboratory protocols, and spatial coordinate integrity. This process yields a standardized, database-ready platform for subsequent 3D subsurface modeling.
2. 3D Spatial Modeling and Geostatistical Estimation
Spatial distribution of target mineralization within domain envelopes undergoes rigorous geostatistical analysis. Utilizing 3D block modeling and variography-guided interpolation techniques (e.g., Ordinary Kriging, Inverse Distance Weighting), wireframe boundaries of mineralized zones are delineated to establish precise volume and grade calculations.
3. International Resource Categorization
Following 3D spatial interpolation, mineral resources are classified into Measured, Indicated, and Inferred categories based on geological continuity, data density, and confidence thresholds under international reporting codes (CRIRSCO: JORC, NI 43-101, SAMREC, KAZRC). Where required, resource matrices are reconciled with national classification frameworks.
4. Technical Reporting and Strategic Roadmap
The final deliverable is an audit-ready Technical Report complete with resource statements, grade distribution plans, cross-sections, block model visualizations, and structured documentation. Concluding sections provide actionable strategic recommendations to optimize downstream exploration, mine planning, and metallurgical testing.
