Improving orebody knowledge with high-resolution rock strength characterization using the Minpraxis Tester
November 23, 2023 | Publications
“The Minpraxis Tester (MPT) is a compression-breakage test device that treats half-core samples continuously length-wise, providing a high degree of rock characterization in comparison to conventional methods. Furthermore, it is able to extract this information while operating as a crusher when used in a conventional assay preparation workflow. This expands the characterized volume of a rock mass to include samples that were recovered for assay purposes, in other words resource core, and would otherwise not be measured with industrystandard methods. The additional resolution on a local-scale (order of 1cm) and the ability to test samples while preparing them for assay results in a significant increase (order of 500 times more) in characterization data over conventional methods.”
