KellGold utilises commercially proven unit operations and learnings from processing of PGM concentrates through the Kell Process. The following benefits could be realised for KellGold (Adams, et al., 2015):- • No constraints on flotation concentrate grades or impurities which could increase float mass pull and recoveries; • Cyanide free gold recovery which negates the need to destroy the cyanide in tailings streams – some countries ban the use of cyanide altogether; • Reduced water usage,

October 2017 / Mining Method Selection
Selecting a mining method is one of the most critical and problematic activities of mining engineering. The ultimate goal of the mining method is to maximise the profit and extraction of the mineral resources while providing a safe working environment. The selection of the mining method is a complex task considering many technical, economic, human and historical factors. Analysing all these factors will assist in identifying the appropriate mining method that is technically feasible for

June 2016 / Who Needs Geology
Very often Companies are faced with budgetary constraints. This results in placing pressure on the time spent on generating Mineral Resource models. Technical Reports often vividly describe a projects’ geological location and the mineralisation mechanisms that have been interpreted to occur. However, seldom do these characteristics get fully imparted on the end Mineral Resource result, resulting in poor Mineral Reserving outputs. Consulting companies often receive Mineral Resource models for review or updating and are readily

May 2017 / Gold Cost Curves
Industry cost curves are valuable tools to benchmark the operational cost performance of an existing operation or new proposed mine project against industry. The industry cost curve indicates the ability of the existing mines to endure cyclical commodity prices and ensure continuous mining operations over time. This measure of a mine’s cash margin per ounce can also be a useful tool for the following:- – Use as a Comparison tool; – Use as an Analytical

Dec 2016 / What on Earth are Rare Earths
The term “rare” in reference to rare earth elements (“REEs”) is not strictly correct and stems from the early 1950s. The complexity of REE ores and elements made the separate economic extraction of individual elements more difficult and costly. Some of the elements are relatively abundant in the earth’s crust but the economic extraction is often not possible. The International Union of Pure and Applied Chemistry defines REEs as the 15 Lanthanide elements plus Scandium
