(TSXV: RZL) (the \"Company\" or \"RZOLV\") today announced the results of independent metallurgical testing conducted by SGS Canada Inc. (\"SGS\") 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.Chart 1: Bottle Roll Leaching Recovery Results - (SGS)To view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/11597/280071_rzolv.jpgFigure 1: Bottle Roll Leaching Recovery Results - (SGS)Test ReagentCal Head (g/t Au)Residue (g/t Au)Recoveries (%)1hr2hrs4hrs8hrs 24 hrs48 hrs72 hrs96 hrsOxide ConsRZOLV339.04.28021.632.241.557.786.397.9-98.7CN357.90.032.357.382.493.599.799.999.999.9Sul...
