Resource estimation and deposit grading often requires complex analysis and review, with just a small change to parameters having a big effect on the results.
To help explorers and miners gain a rapid and reliable read on their geological data, no matter how often it changes, MICROMINE has introduced a range of new charts in its new Micromine 2020 software release.
Micromine product strategy manager Mark Gabbitus said the Micromine 2020 Chart suite would allow users to set up charts according to their specific requirements, rather than configuring generic chart options.
“Micromine 2020 is all about customisation and precision and the new charts functionality delivers just that,” Gabbitus said.
“The charting tools target common situations where mining professionals face decisions without clear-cut answers, and the charts are able to support the decision-making process by presenting all the information in a highly accurate, interactive and visual way.
“Each chart is dedicated to a specific geological or geostatistical scenario and can be exported in various formats depending on user preferences.”
The new charting tools are all fully integrated with the rest of Micromine 2020’s functions and can be linked to the corresponding layer in a 3D Vizex view.
With full support for expressions and auto-labelling options, the tools also produce highly readable charts without resorting to generic labels.
Micromine 2020 users have a range of charting options to choose from in the new release, which is due to hit the market in November 2019, including:
By inspecting geological grade differences at the contact points between two wireframe domains, geologists can readily view and determine grade differences to develop appropriate management approaches.
This is important as a rapid change in grade difference, known as a hard boundary, requires very different management to a slow change or soft boundary.
Grade tonnage curve
As the final size of a mineral deposit is defined by its grade and tonnage, a grade tonnage curve chart has been added to Micromine 2020 to visually maps and depict this end stage.
Micromine 2020 users can create and view histograms that illustrate the multiple variables of mineral deposits to gain a better understanding of the relationship between those elements to, ultimately, inform production approach and methodology.
For example, the multivariate histogram could be used to identify gold quantities found in quartz, which is positive, or silica found in iron ore, which would be considered as a negative outcome.
As many parameters underpin the interpolation of drillholes used to estimate grades within a mineral deposit, a small change to one or more parameter can have a big impact on the estimation result.
Micromine 2020’s search neighbourhood chart analyses the properties of different drillhole samples taken throughout a site or ‘neighbourhood’ and gives users a visual presentation of how parameter changes affect the result. The outcomes can be reviewed, considered and adjusted.
Added to this, Micromine 2020 features a Quantitative Kriging Neighbourhood Analysis (QKNA) chart.
This chart offers interactive workflow to set up experiments that combine one or more kriging parameters to graph results and produce an optimal grade estimation.
After geologists create an initial block model, by assigning grade estimations to the many locations within a mineral deposit (which involves both known and unknown geological and numerical decisions), Micromine’s 2020 swath plot graph steps in to deliver the ultimate, visual-based data validator.
The swath plot functionality compares one-dimensional graphs from related data sources to determine whether the block model accurately represents reality. This allows users to make modelling corrections at early planning stages before they become more permanent mistakes.
Micromine 2020’s ternary diagram provides a compelling visualisation of three-component data, which is essential for geochemistry where databases comprise three elements.
This interactive multi-chart tool strips out outlining high-grade data and assigns a lower, more representative resource value to allow users to make more accurate resource estimations.
This chart, along with the other range of intuitive and sophistication charting tools, are all part of the new Micromine 2020 release, which offers seamless mine modelling, estimation, design, optimisation and scheduling capacity.
Already trusted by more than 15,000 mining and exploration users around the world, MICROMINE’s comprehensive and easy-to-use exploration and 3D mine design solution offers miners the flexibility that is need, when it’s needed.
In addition to the new charts, Micromine 2020 boasts a new ring design module and Stope Optimiser, an improved scheduler and advances in the Implicit Modelling and Pit Optimiser modules.
