ZODIAC GOLD ENGAGES SGS SOUTH AFRICA FOR PRELIMINARY METALLURGICAL TESTWORK PROGRAM
Zodiac Gold Inc. has formally engaged SGS South Africa Pty. Ltd., a globally recognized leader in inspection, verification, testing and certification, to conduct a preliminary metallurgical test work program on gold-bearing samples from its exploration portfolio. The study will provide the foundation for more detailed metallurgical test work and forms a key part of the company's goal to advance the Arthington target.
David Kol, chief executive officer of Zodiac Gold, commented: "This test work marks an important step in derisking our assets and improving our understanding of mineral recoverability. The results will inform our flowsheet development and set the foundation for more detailed studies. Working with SGS gives us confidence that the results will meet the highest standards of technical rigour and reliability."
The metallurgical test work is designed to assess the amenability of an approximately 18-kilogram (kg) sample to gravity separation, cyanidation and acid leaching techniques, with a focus on optimizing gold recovery, while also evaluating associated copper (Cu) and nickel (Ni) leaching behaviour. The test program will cover:
- Gravity recovery (GRG): utilizing a Knelson centrifugal concentrator to assess free gold content and efficiency of gravity separation;
- Diagnostic leach tests: sequential cyanidation and oxidative leaching to evaluate the deportment of gold within different mineral matrices;
- Reagent consumption studies: quantifying the required doses of cyanide and lime, vital for process design and cost estimation;
- Leach kinetics and residence time studies: evaluating gold dissolution efficiency at intervals from four to 48 hours to determine optimal processing times;
- Preg-robbing and grind sensitivity tests: understanding the impact of particle size and activated carbon addition on gold recovery;
- Acid leaching: a separate test for evaluating the extraction of Cu and Ni under controlled pH and temperature conditions, using sulphuric acid.
A composite sample of quarter-core from six drill holes along the one-kilometre-long (km) mineralized trend at the Arthington target will be processed, with careful preparation, milling, splitting and chemical analysis at each stage to ensure accuracy and representativeness.
The test work will commence upon receipt of the sample at SGS's state-of-the-art facility in Randfontein, Gauteng, and results are expected in early Q3 (third quarter) 2025.
The company is currently undertaking a 2,000-plus-metre (m) diamond drilling program along a one km mineralized trend at the Arthington target, which is part of a 16 km long soil anomaly, including the Arthington, Ben Ben, Feh Feh and Youth Camp targets.
