Exploration company Genesis Resources (GES) has completed metallurgical test work on core samples from its Plavica project in North Macedonia.
During a core drilling program at the project in 2015 and 2016, company staff collected five composite samples. The samples were taken from various drill holes, and mixed together on site at Genesis’ core processing facility in Probistip, North Macedonia.
The core samples were then transported to the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Perth, Western Australia. The CSIRO conducted metallurgical test work on the oxide gold core, which came in five separate 15 kilogram samples.
This metallurgical testing process used by the CSIRO involved a “Clean Mining” technique. After the crushing and milling processes were completed, the CSIRO used a non-toxic, water soluble, non-flammable, inorganic compound to extract the gold.
Within the first five hours of the CleanTech process, just under 80 per cent of the gold from the Plavica project was recovered. Of the five composite samples, the lowest gold recovery rate was 80 per cent, whilst the highest was 85 per cent.
Based on a grind size of 75 microns, the average gold recovery rate of the five composite samples was 83 per cent after 24 hours.
Based on these results, Genesis Resources is now planning further test work at its Plavica project in North Macedonia. This future testing may include work involving bulk samples and differentiation of ore types.
At the end of last week, Genesis Resources closed in the grey for 1.8 cents per share.
