Integrating the Theory of Sampling into Underground Mine Grade Control Strategies

Abstract: Grade control in underground mines aims to deliver quality tonnes to the process plant via the accurate definition of ore and waste. It comprises a decision-making process including data collection and interpretation; local estimation; development and mining supervision; ore and waste destination tracking; and stockpile management. The foundation of any grade control programme is that of high-quality samples collected in a geological context. The requirement for quality samples has long been recognised, where … Show more

“…This option involves taking half or whole core samples and processing the entire sample by, for example, the single-stage GRG test [18], large-scale screen fire assay and/or bulk leaching. Dominy et al [37,80] applied whole HQ 2-m composites (approximately 17 kg samples) to a coarse gold orebody. A single-stage GRG test with tails leach (and some flotation testwork) was used to provide data for GRG and tails leach recovery, and head grade.…”
