(TSXV: RZL) (the \"Company\" or \"RZOLV\") today reported the results of a bulk-scale vat leach metallurgical test conducted at an independent, operating gold mine in Arizona, marking a significant milestone in the commercial validation of the Company's proprietary non-cyanide gold leaching technology.The program represents RZOLV's most advanced scale-up validation to date, moving beyond laboratory conditions to evaluate metallurgical performance, solution chemistry, reagent stability, hydrodynamics, and operability under representative operating conditions and at meaningful tonnage.Bulk-Scale Test Highlights:73.5 tonnes of low-grade oxidized gold mineralization were processed at an operating mine in Arizona.The test achieved an overall gold recovery of 67.51% over 40 days under the specific conditions evaluated, with recoveries comparable to laboratory-scale reference tests conducted using 1,000 ppm sodium cyanide.The RZOLV™ leach solution demonstrated predictable scale-up behavior, with metallurgical performance consistent with prior laboratory-scale test work.Solution chemistry remained stable throughout the test, maintaining targeted pH and oxidation-reduction potential (ORP) ranges, with no evidence of instability, precipitation, compaction, or channeling.Leached residues exhibited low residual gold content and maintained favorable permeability characteristics throughout the test period.Effective gold adsorption onto carbon was achieved, confirming compatibility with conventional carbon adsorption and electrowinning circuits.Doré production and final weight were consistent with calculated carbon loadings and overall metallurgical accounting.CEO CommentaryDuane Nelson, President and CEO of RZOLV Technologies Inc., commented: \"This bulk-scale vat leach test represents an important inflection point for RZOLV. Processing more than 73 tonnes of ore at an operating mine allowed us to validate not only metallurgical recovery, but solution stability, hydrodynamics, reagent behavior, and carbon performance under real-world conditions.\"\"The predictable scale-up behavior obs...
