Your Resource Estimation May be Fundamentally Flawed Without a Good Geological Model

Resource estimation is a compilation of data collection and analysis, geological interpretation and geostatistical estimation. The process is expertly summarized in a recent article by Erik Ronald, Is your Mineral Resource or Reservoir Model Fundamentally Flawed? – The Importance of Domaining and Stationarity to Geologists. Stationarity of our data and the influence of geology on the distribution of grades are key underlying concepts of this process. The semi-variogram is the principle analytical tool for establishing whether or not our data posesses stationarity. Stationarity assumes the

Better Instrumentation Requires Better Skills in Mineral Processing

A recent article in CIM Magazine (October 2015) titled “A Measure of Control” describes how better instrumentation and a drive for efficiency are making big changes to the way mineral processing plants are run. When commodity prices were strong and rising, mining companies could afford minor inefficiencies in their plants. That is rarely the case in these days of lower-grade deposits, lower metal prices and economic pressure from every direction. There has been significant progress in automated instruments recently. These measure crucial parameters in the
