RZOLV Technologies Inc. Announces Independent SGS Lab-Scale Test Results on Gravity Concentrates - 98.7% Gold Recoveries
RZOLV Technologies Inc. announced the results of independent metallurgical testing conducted by SGS Canada Inc. evaluating the performance of RZOLV's proprietary, non-cyanide gold leaching formula on gravity concentrate material. The test program was carried out at SGS' Burnaby, British Columbia metallurgy laboratory and compared gold recovery achieved using RZOLV™? against conventional sodium cyanide under controlled bottle-roll leaching conditions. The material tested consisted of both oxidized and sulfide-based gravity concentrates sourced from 2 separate gold projects located in Alaska. The material was prepared to a particle size of 80% passing 2 mm. The objective of the test work was to evaluate the technical performance of RZOLV™? relative to cyanide on high-grade gravity concentrate material, particularly in contexts where cyanide use may be constrained or less effective. Under the specific laboratory test parameters evaluated by SGS, RZOLV™? achieved gold recoveries of 98.7% on oxide-based gravity concentrates and 89.4% on sulfide-based gravity concentrates over a 96-hour leach retention time. Under the same laboratory conditions, a reference solution containing 2,000 ppm sodium cyanide achieved gold recoveries of 99.9% and 90.7%, respectively. The Company notes that results are specific to the material tested and the conditions applied. Further test work is ongoing to evaluate performance across a broader range of ore types, mineralogical characteristics, and operating conditions. RZOLV™? continues to focus on third-party validation and disciplined test programs as it advances the evaluation of its technology for potential commercial applications.
