Mining Geology & Resource Estimation

SRK has considerable experience in managing exploration programmes, interpreting the structural setting of ore deposits and in drilling, sampling and assaying techniques. This enables us to help our clients find, delineate and estimate the size and quality of their mineral deposits effectively. Our team of resource geologists has a wealth of experience in the majority of commodities and mineral occurrences.

Data quality and sampling density are the cornerstones of this work and we provide specific services in this area. In addition, we use state of the art software to produce 3D models of the geometry of the mineralisation, as well as statistical and geostatistical methods to determine and model the distribution of the commodity of interest within these. This enables us to then report Mineral Resource Estimates in line with international reporting codes, and also provides a good basis for mine planning and subsequent project evaluation exercises.

Our overall approach is to tailor our input to our clients’ particular needs, whilst maintaining an independent role for reporting of resources and reserves in the public domain.

SRK's structural geologists help manage exploration and mining risks, reduce capital costs, and minimize mining hazards.
Most ore deposits formed within tectonically active areas, such as ancient basins and orogenic belts. It is no wonder then that the vast majority of mineral deposits are affected or controlled, to a greater or lesser extent, by geological structures. From the perspective of mineral exploration and mining, the potential...
An evaluation of the mineralogy and petrology of ore minerals and associated gangue are essential keys to understanding the genesis and mineral associations of ore deposits. Additionally these studies are fundamental in the assessment of the potential methods for mineral processing. Expertise and Facilities SRK has developed in- house expertise...
Effective, efficient and secure electronic storage and validation of technical data is a fundamental aspect of exploration, Mineral Resource estimation and mine planning. SRK provides services and solutions to capture, validate and manage your technical data and communicate the results with precision and clarity, in accordance with international reporting codes...
SRK optimises sampling procedures for methodology and audits samples for quality.
The collection of reliable samples from a mineral prospect or mine is an essential basis for the production of an accurate resource inventory. The strategy to be adopted must thus be carefully designed so that, at each stage of the process, the chance of taking biased, unrepresentative or contaminated samples...
SRK reviews both quality assurance / quality control procedures and data, to ensure data quality.
Appropriate Sampling and QA/QC is essential in all aspects of the evaluation process, to ensure the best estimates are achieved; the quality of an estimate is dependent on the quality of the data used. Approach SRK have experienced personnel who can audit, review and advise on quality control procedures in...
Appropriate 2D and 3D computerised geological and mineralisation models of a mineral deposit are a funamental element of Mineral Resource estimation. Appropriate modelling and domaining yields the most robust estimate from a given sample base. Approach SRK utilises a wide variety of computerised modelling methodologies, selected to suit the deposit...
Statistical and geostatistical analyses are essential in understanding the grade distribution and continuity in your deposit. SRK can apply knowledge and experience in this field to assist in optimising drilling and sampling strategies and grade estimation domaining and kriging parameters. Understanding geostatistics can assist in Mineral Resource classification and quantifying...
Approach Grade modelling is an essential requirement in understanding your deposit. SRK utilises a wide range of techniques to model your deposit, across a wide range of commodities and deposit styles. Our approach to grade modelling is always based on the geology of your deposit: we aim to tailor the...
SRK acts on grade control data to minimize differences between planned and actual mine production.
Understanding grade distribution and optimising mining selectivity through grade control is essential to achieving the mine plan. SRK has the expertise to implement, monitor, analyse and react to grade control data. This allows the results to be reconciled against planned production and actual plant data. Minimising difference between planned verses...
Natural variability and sampling uncertainty influence location and accuracy of economic grades in an orebody model. Each deposit therefore needs to be considered on its own merits. SRK has a large team of ‘Competent Persons’ experienced in assessing such uncertainty and applying Mineral Resource classification in accordance with international reporting...
