TRX Gold Advancing Processing Plant Expansion Throughput To Be Greater Than 3,000 TPD

TORONTO, Nov. 04, 2025 (GLOBE NEWSWIRE) -- TRX Gold Corporation (TSX: TRX) (NYSE American: TRX) (the “Company” or “TRX Gold”) is pleased to provide an update on the processing plant expansion and upgrade project at the Buckreef Gold Project (“Buckreef Gold”). As outlined in the Company’s Preliminary Economic Assessment (“PEA”) filed on May 27, 2025, the Company’s plan is to expand and upgrade the processing plant over the next two years to increase throughput and recoveries, followed by a transition from open pit to underground mining. The PEA initially contemplated a single 3,000 tonne per day (“TPD”) processing circuit for sulphide ore that was expected to produce average annual gold production of approximately 62,000 ounces of gold over 17.6 years at a capital cost of approximately US$30 million for the processing plant expansion. The Company is now planning and has begun executing on a larger processing facility than was initially contemplated in the PEA, consisting of a 3,000+ TPD processing circuit for sulphide material as well as a 1,000 TPD processing circuit for oxide and transition material, and tailings retreatment. The 1,000 TPD processing circuit is also expected to be capable of processing sulphide material at a reduced throughput level and lower recovery rates (approximately 80+% versus 87+% in the larger 3,000+ TPD circuit for sulphide material) and can be upgraded to have similar specifications to the 3,000+ TPD processing circuit. The newly designed processing plant expansion will consist of plant upgrades and new components being integrated into the existing 2,000 TPD processing plant at a capital cost of approximately US$30 million, in line with the PEA, and financed from internally generated cashflow over the next 18-24 months. The increase in expected throughput from the larger processing circuit is now expected to produce average annual gold production in excess of the 62,000 ounces of gold published in the PEA. Stephen Mullowney, TRX Gold CEO says “The planning and execution of the expanded processing plant is well underway, and it is now envisioned to be larger than anticipated in the PEA, which should lead to higher gold production than was anticipated in the PEA. Our expansion will be rolled out over the next 18-24 months with operational improvements throughout that period which are expected to positively impact financial performance. Since our first gold pour in 2021, the Buckreef Gold processing plant has completed three expansions, increasing its capacity from 360 TPD to 1,000 TPD and subsequently to 2,000 TPD. The forthcoming improvements over the next 18-24 months will continue this growth trajectory. The overall project continues to be on budget and in line with capital cost estimates in the PEA. The Company is currently paying for these upgrades out of cash flow from operations and available liquidity lines, while at the same time continuing to improve overall working capital.” 3,000+ TPD Processing Circuit The 3,000+ TPD Processing Circuit will consist of the following: A separate and new jaw crusher/apron feeder feeding a Semi Autogenous Grind (“SAG”) mill in closed circuit utilizing the largest ball mill in current 2,000 TPD processing circuit;The installation of a new flotation and fine grind unit, which will concentrate 87%-90% of gold into less than 15% of total mass, followed by ultra-fine grinding and intensive cyanide leaching;Adding two pre-leach thickeners for feeding high-density slurry to the carbon in leach (“CIL”) circuit; andThe CIL circuit will utilize the existing large CIL tanks, with additional CIL tanks being added to this circuit. 1,000 TPD Processing Circuit The 1,000 TPD Processing Circuit will consist of the following: The existing 3-stage crushing circuit, which will receive immediate upgrades to improve throughput in the short term including: (i) replacing the apron feeder under the jaw crusher with a more robust unit; (ii) strengthening foundations and reducing vibrations in secondary and tertiary cone crushers; (iii) modifying screen deck for improved crushing circuit efficiency; and (iv) overhauling conveyor belts, drives, alignment systems, cleaning systems, and upgrading electromagnet and weightometers; andThe existing three smaller 360 TPD ball mills as well as smaller CIL tanks.This circuit can also be upgraded to have similar specifications as the 3,000+ TPD processing circuit to achieve similar recovery rates for sulphide material by integrating it into the floatation and fine grind unit and adding a pre-leach thickener. Overall Plant Upgrades Overall Plant Upgrades include: The ball mills will receive a series of immediate upgrades including: (i) installation of new feeders; and (ii) improvements in power draw and feed control, integrating advanced belt feeders and variable speed mill motor drives with enhanced process controls.All CIL tanks will receive immediate upgrades including: (i) upgraded CIL agitators and inter-tank transfer systems to manage increased flow and slurry density; (ii) upgraded pumps and screens; and (iii) enhanced reagent dosing and measurement systems. These upgrades are expected to allow for higher throughput and more stable operating conditions.Installing high-purity oxygen injections using an oxygen plant and Aachen® reactor to increase oxidation and recovery.Replacing four small electrowinning units with a larger, expandable cell and establishing a new adsorption, desorption and refining (“ADR”) plant for elution, acid treatment and regenerating stripped carbon. Carbon handling will become hands-off and automated, and a fines screening process will be implemented to reduce gold solution losses. A new, secure gold smelting room will also be constructed for the larger processing plant; andA cyanide destruction circuit will also be introduced for tailings management. Expansion and Overall Plan Project Status The integrated project comprises two primary tracks: Track 1: Overall Plant Upgrades, which will boost reliability and performance, scheduled for completion in fiscal 2026. This phase includes plant efficiency improvements as detailed above along with constructing the 18 meter diameter pre-leach thickener and installing new ADR & Gold Room facilities; andTrack 2: Complete 3,000+ TPD and 1,000 TPD processing circuits, with scheduled completion in fiscal 2027. Both throughput and recovery rates will gradually increase from now to the scheduled completion date. An owner's project team has been appointed and mobilized onsite. The project schedule is being actively managed and status by work stream is as follows: 3,000+ TPD Processing Circuit 18 meter Pre-leach Thickener: Manufacturing 95% complete, shipping in December 2025.Processing Circuit Flotation Plant and Ultra-Fine Grind Mill: Award manufacturing contracts in November 2025.Processing Circuit SAG Mill: Award manufacturing contracts in January 2026. 1,000 TPD Processing Circuit Apron Feeder: Manufacturing 80% complete, shipping in November 2025 Overall Plant Upgrade Aachen® Reactor: Manufacturing 100% complete, shipping in November 2025.Leach Tank Agitators and Inter-tank Screens: Manufacturing 50% complete, shipping in December 2025.Oxygen Plant: Manufacturing and assembly 75% complete, shipping in December 2025ADR Plant: Manufacturing contract awarded in November 2025, construction slated to begin in April 2026.
