Resource Estimation ACALA Consulting Geology & Geostatistics Expertise
ACALA specializes in mineral resource estimation using advanced geostatistical modeling, geological interpretation, and QAQC validation. Our geologists deliver accurate, independent resource evaluations aligned with global reporting standards (Feasibility Study, SNI, KCMI, JORC, SAMREC, NI 43-101), helping mining companies and investors secure financing and manage project risks with confidence
Resource estimation is a fundamental skill of the ACALA Consulting geology team and lies at the core of our practice. From conducting geological interpretations manually or using advanced software, to applying sophisticated geostatistical modeling techniques, ACALA geologists provide the expertise needed to secure financing or advance your project.
We integrate geology throughout the resource process, utilizing the latest technologies at each stage — from validating source data and QAQC checks, to variographic analysis, kriging neighborhood studies, and global or local resource estimation.
Our resource estimation process includes:
- Validating source data, including laboratory assay reports, drilling methods, collar locations, and downhole survey methods
- Assessing QAQC data
- Reviewing or creating domain interpretations, including Geological Matrix Analysis
- Conducting exploratory data analysis
- Performing variographic analysis
- Conducting kriging neighborhood analysis
- Estimating global and local resources using the most suitable methodology
We thoroughly review the data and information provided by our clients and offer informed advice to ensure confidence in understanding the risks and uncertainties associated with your project resources. This may involve using linear or non-linear techniques, which our geostatisticians will explain clearly. We conduct independent mineral resource estimations suitable for public reporting based on SNI, KCMI, JORC, SAMREC, and NI 43-101 standards.
At ACALA Consulting, we collaborate closely with your team during the resource estimation process to ensure a cooperative outcome and leave a positive legacy.
Whether providing geological interpretation, resource evaluation, or statistical analysis, we leverage our extensive resource modeling experience to deliver quality outcomes while managing geological uncertainty.
Geostatisticians
Our geology team comprises high-end resource and mining geology experts. Geostatistical analysis is a key competency, with of our geologists holding postgraduate qualifications in geostatistics. We have the in-house expertise to solve complex problems, grounded in sound scientific principles. A core principle of our team is to ensure geology is considered throughout the entire resource process.
We specialize in single and multi-element analysis, offering advice on all aspects from confirming domains and boundary conditions, comparing drill data types, characterizing spatial continuity and nugget effect, to estimation methodologies including linear and non-linear techniques. We often review existing geostatistical estimation parameters, such as composite lengths, top cut strategy, variogram model parameters, estimation block size, and estimation method.
At ACALA, we have experience ranging from kriging to recoverable resource estimation using local uniform conditioning and simulation. Using GEOVIA Surpac & 3DEXPERIENCE, we apply the most advanced techniques to your project, always tempered with a practical approach.
Examples of our work include:
- Conducting a Drill Hole Spacing Analysis for a client to define quantitative inputs for resource classification and drill hole planning
- Developing a geostatistically sensible domaining strategy for a specific lithological unit and using simulation methodology to evaluate the risk associated with interpolation within that unit
We conduct thorough reviews and offer informed advice to ensure confidence in understanding the risks and uncertainties associated with your project resources.
