Geology & Resource Estimation

The collection of reliable samples from a mineral prospect or mine is an essential basis for the production of an accurate resource estimate The strategy to be adopted must thus be carefully designed so that at each stage of the process, the chance of taking biased, unrepresentative or contaminated samplesEstimation of a mineral resource is the starting point to successful mine development A reliable estimate combines good quality and relevant data, competent geological interpretation and a methodology for producing from that data and interpretation, a reliable representation of the mineralized deposit, its geometry, its grade distribution, its metallurgical variability and its densityMineral Resource and Ore Reserve Estimation The AusIMM

Evaluation of Acid Digestion Procedures to Estimate

In minerals analyses, the digestion process is the limiting factor as to how much time the entire procedure takes and also concerns the efficiency of recovering the actual amount of mineral present in the sample (McCarthy and Ellis, 1991) Considering that the interactions of minerals with organic matrices may vary depending on the analyzedmineral resources prior to mine design and planning This definition is based on geological knowledge of the orebody and on sample information from an exploration drilling grid, usually with infill drilling in the areas to be extracted during the first years of the project The first step in resources estimation is an exploratory analysis aimed atGeostatistical estimation of mineral resources with soft
