Vancouver, British Columbia--(Newsfile Corp. - January 12, 2026) - RZOLV Technologies Inc. (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.

CEO Commentary
Duane Nelson, President and CEO of RZOLV Technologies Inc., stated: "We are very pleased with the independent metallurgical testing conducted by SGS. Under the test conditions evaluated, RZOLV's non-cyanide solution demonstrated gold recoveries and leach kinetics comparable to those achieved using cyanide-based reference methods commonly applied prior to smelter treatment, under the specific laboratory conditions evaluated.
These results represent a meaningful technical milestone for the industry and support RZOLV's potential to provide a cost-effective alternative to the current cyanide, and smelter-based methods used today for the treatment of gold-bearing concentrates."

Key Test Highlights - Independent SGS Metallurgical Results
Independent third-party validation by SGS - All metallurgical test work was conducted by SGS Canada Inc. at its Burnaby, BC laboratory under controlled conditions, providing independent confirmation of performance using industry-standard methods
Excellent gold recoveries on gravity concentrates - RZOLV™ achieved 98.7% gold recovery on oxide gravity concentrates and 89.4% recovery on sulfide gravity concentrates over a 96-hour leach cycle, demonstrating strong dissolution performance on high-grade materials
Performance comparable to cyanide under identical conditions - Under the same laboratory parameters, RZOLV™ delivered gold recoveries and leach kinetics that were directly comparable to a 2,000-ppm sodium cyanide reference solution, confirming technical parity without the use of cyanide
Demonstrated effectiveness on both oxide and sulfide concentrates - The ability to achieve high recoveries across two distinct concentrate types suggests broad applicability to gravity and flotation concentrate streams where cyanide or smelting may be constrained or uneconomic
Potential alternative to smelter-based concentrate treatment - Management believes these results support RZOLV™'s potential to provide a cost-effective, non-cyanide alternative to smelter treatment for certain gold concentrates - a market segment historically limited by high costs, logistics, and ESG constraints
Material sourced from real operating jurisdictions - Test material originated from two separate gold projects in Alaska, reinforcing that the results are based on representative, real-world concentrate material rather than synthetic or idealized samples
Strong technical foundation for scale-up and further optimization - While results are specific to the material and conditions tested, the Company has emphasized disciplined test programs and ongoing evaluation across a broader range of mineralogies and operating parameters as it advances toward commercial deployment
