RZOLV hits 97.0% gold recovery on copper-gold ore without pretreatment

Vancouver, British Columbia--(Newsfile Corp. - April 16, 2026) - RZOLV Technologies Inc. (TSXV: RZL) (OTCQB: RZOLF) (FSE: S711) ("RZOLV" or the "Company") is pleased to report the results of recent metallurgical test work in which the Company achieved approximately 97.0% gold recovery on a complex copper-gold ore using the RZOLV formula, without pretreatment. The tested material graded approximately 9.6 g/t gold and 2.12% copper and is hosted within an alkaline gold-copper porphyry system. The gold mineralization is interpreted to be low-sulphidation epithermal mineralization.

The Company believes these results are significant because copper-bearing gold ores are widely recognized as challenging for conventional cyanide processing. SGS technical publications note that copper minerals can materially increase cyanide consumption and complicate solution management, and that where cyanide-soluble copper becomes significant, operators may consider adding a SART circuit to precipitate copper sulphide and recover cyanide for recycle. By achieving approximately 97.0% gold recovery on this copper-bearing ore without pretreatment, RZOLV believes the test work supports the potential for a simpler and potentially lower-cost processing route relative to a conventional cyanide alternative on similar mineralization.

RZOLV Technologies conducted bottle roll leach tests on the subject material to evaluate performance under controlled laboratory conditions. The test was conducted at 20% pulp density on a 150 g sample crushed to a target size of -500 µm and run for 168 hours with solution sampling at regular intervals.
