RZOLV REPORTS APPROXIMATELY 97.0% GOLD RECOVERY ON COMPLEX COPPER-GOLD ORE WITHOUT PRETREATMENT, HIGHLIGHTING POTENTIAL TO SIMPLIFY FLOWSHEETS VERSUS CYANIDE

Rzolv Technologies Inc. has released the results of recent metallurgical testwork in which the company achieved approximately 97.0-per-cent gold recovery on a complex copper-gold ore using the Rzolv formula, without pretreatment.

The tested material graded approximately 9.6 grams per tonne gold and 2.12 per cent 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 an SART circuit to precipitate copper sulphide and recover cyanide for recycle. By achieving approximately 97.0-per-cent gold recovery on this copper-bearing ore without pretreatment, Rzolv believes the testwork 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-per-cent pulp density on a 150-gram sample crushed to a target size of minus 500 micrometres and ran for 168 hours with solution sampling at regular intervals.

Analytical basis

Testing was carried out at ambient laboratory temperature. Process pH and oxidation-reduction potential were monitored during the tests. Solution samples were collected at closely spaced intervals during the initial four hours to characterize early-stage kinetics, followed by additional sampling at 24, 48, 72, 96 and 120 hours.

Gold extraction values reported herein are based on internal solution and residue calculations generated during the test program. Final solid residues from the test were subsequently submitted to ALS Laboratories for independent assay verification. Results are presented above.

"This is an important result for Rzolv because it goes well beyond recovery alone," said Duane Nelson, president and chief executive officer of Rzolv Technologies. "To achieve this high gold recovery on a copper-bearing complex ore without pretreatment suggests that Rzolv may offer a practical alternative in mineral systems where cyanide can become penalized by copper. If supported by further work, this could translate into simpler plant design, lower capital costs, lower reagent penalty and the potential to avoid the need for a costly SART circuit that might otherwise be required under a cyanide flow sheet."

The company believes the implications of this result may include:

• Potential flow sheet simplification by reducing or potentially eliminating the need for a separate copper-cyanide management circuit;
• Lower capital intensity, through the possible avoidance of an SART plant and related supporting infrastructure;
• Reduced operating complexity, including fewer unit operations and less process management associated with copper-cyanide recycling;
• Improved project economics, particularly for lower-grade or copper-bearing gold ores where processing costs are highly sensitive to reagent consumption and circuit complexity; and
• Expanded market relevance for Rzolv, further supporting its potential application in ore types that can fall within conventional cyanide penalty windows.

The company further notes that the absence of pretreatment in this testwork is particularly encouraging. Pretreatment steps can add substantial cost, time, technical complexity and permitting burden to a project. Demonstrating high gold recovery without such steps may improve the commercial attractiveness of Rzolv for certain complex orebodies.

These are ore types where conventional cyanide does not merely underperform environmentally, but can become economically burdened by complexity, copper interference, pretreatment requirements or downstream circuit additions. If this result is supported by further work, it suggests that Rzolv may not be simply an alternative to cyanide, but a superior solution in selected copper-bearing gold systems. The company intends to continue metallurgical work to further evaluate recovery performance, reagent optimization, copper deportment, process economics and scale-up across broader sample sets and operating conditions.
