RZOLV TECHNOLOGIES ANNOUNCES INDEPENDENT SGS LAB-SCALE TEST RESULTS ON GRAVITY CONCENTRATES - 98.7% GOLD RECOVERIES

Rzolv Technologies Inc. has released the results of independent metallurgical testing conducted by SGS Canada Inc. evaluating the performance of Rzolv's proprietary, non-cyanide gold leaching formula on gravity concentrate material.

The test program was carried out at SGS's Burnaby, B.C., 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 sulphide-based gravity concentrates sourced from two separate gold projects located in Alaska. The material was prepared to a particle size of 80 per cent passing two millimetres. The objective of the testwork 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 limits evaluated by SGS, Rzolv achieved gold recoveries of 98.7 per cent on oxide-based gravity concentrates and 89.4 per cent on sulphide-based gravity concentrates over a 96-hour leach retention time. Under the same laboratory conditions, a reference solution containing 2,000 parts per million sodium cyanide achieved gold recoveries of 99.9 per cent and 90.7 per cent, respectively.

The company notes that results are specific to the material tested and the conditions applied. Further testwork is continuing 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.

Chief executive officer commentary

Duane Nelson, president and CEO of Rzolv, 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."

The metallurgical results reported herein are laboratory scale only and are not intended to support, nor should they be construed as supporting, any mineral resource, reserve or production estimates.

Key test highlights -- independent SGS metallurgical results:

• Independent third party validation by SGS: All metallurgical testwork was conducted by SGS Canada Inc. at its Burnaby, B.C., laboratory under controlled conditions, providing independent confirmation of performance using industry-standard methods.
• Excellent gold recoveries on gravity concentrates: Rzolv achieved 98.7-per-cent gold recovery on oxide gravity concentrates and 89.4-per-cent recovery on sulphide gravity concentrates over a 96-hour leach cycle, demonstrating strong dissolution performance on high-grade materials.
• Performance comparable with cyanide under identical conditions: Under the same laboratory assumptions, Rzolv delivered gold recoveries and leach kinetics that were directly comparable with a 2,000-part-per-million sodium cyanide reference solution, confirming technical parity without the use of cyanide.
• Demonstrated effectiveness on both oxide and sulphide 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 environmental, social and governance 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 continuing evaluation across a broader range of mineralogies and operating assumptions as it advances toward commercial deployment.
