Principles of Using Microdiamonds for Resource Estimation: 1—the Impact of Mantle and Kimberlite Processes

The suitability of micro-diamonds for local (blocked) resource estimation – opportunities and challenges

“…These debates have centred round the suitability of microdiamonds for global and zonal average grade calculations. The impact of mantle processes and geology on microdiamond-based estimation methods has already been addressed (Stiefenhofer et al, 2016), as well as key features of the microdiamond estimation process (Stiefenhofer et al, in prep.). In this paper the debate is taken a step further and the suitability of microdiamonds for use in local block estimates was investigated through analysis of key geostatistical properties.…”
