Resource modelling & GIS
The culmination of all the geological and sampling data into a 3D geological model enables the grade estimations and grade distributions to be reported in a geological grade block model.
A block model is a 3D representation of a mineral deposit used to estimate the quantity and quality of minerals in a specific area. Each block is assigned values for mineral content and other geological parameters, enabling mining companies to understand the distribution of minerals within the deposit and plan their extraction accordingly.
Geostatistical analysis is a powerful tool for informed decision-making in mineral resource estimation, mine planning, and production management. This statistical method considers the spatial variability of geological and mineralogical data, resulting in more accurate and precise estimates of mineral resources.
Grade-tonnage reporting is a standardised method used in the mining industry to visualise the quantity and expected grades of a deposit after applying specific cut-offs. It allows mining companies to compare their deposits with others in the industry and assess the potential profitability of their operations.
Depleting Mining Block Models
MINROM assists in depleting, editing, updating, and incorporating new data into mining block models. This process ensures that the block models accurately represent the evolving nature of the deposit as mining progresses.
Resource modelling is a critical process in mineral projects where estimates of size, grade, and quality of the deposit are made. Mining companies rely on resource modelling to make informed decisions about mining locations and optimise extraction methods for efficiency and cost-effectiveness.
Mineral Resource Statements
Mineral resource estimates derived from resource modelling are classified based on geological and statistical confidence and reported according to industry standards or specific reporting codes such as NI 43-101, JORC, SAMREC, SME, or PERC. These statements provide essential information about the mineral assets of a company.
Competent Person Reports
Competent Person’s Reports (CPRs) are prepared by qualified and experienced individuals to provide independent assessments of a company’s mineral assets. These reports are based on all available geological, technical, and economic data and must comply with specific reporting codes, ensuring transparency and accuracy.
Resource Reconciliations (F1 and F4)
Resource reconciliation involves comparing estimated mineral resources from block models with actual production data to identify discrepancies or variations. In performing resource reconciliations, mining companies can ensure the consistency between estimated resources and actual production. This allows for the complete analysis, optimisation and identification of discrepancies between resource models and actual production grades and tonnages.
