We carve success of Mining Projects
Success of Mining projects depends on reliable estimation of the grade of mineralization. Our team of licensed geologists, geotechnical and environmental engineers have extensive experience in both underground and open pit mining. They posses strong understand of mining and mineral processing and supports mineral resource and reserves estimations.
Mineral Resource Estimation
- Exploration drilling assay QA/QC
- Geological mapping and interpretation of sections and plans
- Mineral domain determination and construction of three-dimensional domain envelopes for grade interpolation constraints
- Assessment of whether to employ restrictions using high grade values (outlier/capping determination)
- Interval composite creation
- Exploratory data analyses (EDA)
- Development and implementation of appropriate grade estimation plans, including consideration of grade and structural domains within the deposit and selection of drillhole assay composites, search distances and search limitations to be used in the estimation.
- Validation of estimates by inspection of sections and plans, and by comparison to nearest neighbour (polygonal) estimates by elevation and coordinates
- Variography calculation to analyse the spatial variability of the mineralization.
Feasibility Studies
Our experts are highly skilled in economic evaluation of mines, estimation of ore reserves, determining deposit grades, testing extraction methods and developing feasibility studies, which are used to determine whether mine development should commence based on commercial viability and financial availability.
Mineral Reserves Estimation
- Base cases to determine the ultimate pit geometry.
- Incremental pits shells developed using different revenue factor or similar method.
- Development of Mine plans
- Pit designs
- Determine which incremental pits will be used as basis for pit phase selection.
- Estimation of mobile mine equipment, fleet selection and supporting equipment
- Development of surface mine facilities and supporting infrastructure
- Mine capital and operating cost development
- Financial modelling
- Underground mining estimations, including cut-off grade/value determination, design shapes to outline production locations, and mine access and ventilation designs and models.

Ore Reserve Estimation
Ore-reserve estimates are based upon the results of exploration and development and analyses of the samples derived therefrom. Unless a deposit is fully developed (and even then, to a lesser degree), certain assumptions have to be made regarding the continuity and grade of ore between exposed faces or drill holes that have been sampled.
Our Value Proposition
Our specialists interpret available information and are able to provide accurate results. We combine the assay values of the samples and interpret the geological criteria and consider the influence of structural conditions on continuity and grade of ore, including loss of ore in mining, dilution with waste which, in turn, may depend on the mining method employed or to be employed, and the cost of mining, which could be used as an important factor in determining the minimum grade of rock that can be classed as ore.
