Zodiac Gold Engages SGS South Africa for Preliminary Metallurgical Testwork Program
Vancouver, British Columbia--(Newsfile Corp. - May 8, 2025) - Zodiac Gold Inc. (TSXV: ZAU) ("Zodiac Gold" or the "Company"), a West- African gold exploration company, is pleased to announce that it has formally engaged SGS South Africa (Pty) Ltd, a globally recognized leader in inspection, verification, testing, and certification, to conduct a preliminary metallurgical testwork program on gold-bearing samples from its exploration portfolio. The study will provide the foundation for more detailed metallurgical testwork and forms a key part of the Company's goal to advance the Arthington target.
David Kol, CEO of Zodiac Gold, commented: "This testwork marks an important step in de-risking 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 rigor and reliability."
The metallurgical testwork is designed to assess the amenability of an approximately 18kg 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 behavior. 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 & Residence Time Studies: Evaluating gold dissolution efficiency at intervals from 4 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 1km long 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.
