MINING COMMENCES AT KINIERO AS PROJECT TRACKS TOWARDS FIRST GOLD IN Q4 CY2025

Robex Resources Inc. has provided an October, 2025, project construction update for its Kiniero gold project in Guinea, West Africa. Robex is on track to deliver first gold at Kiniero in calendar Q4 2025.

Highlights:

• Robex's Kiniero gold project in Guinea remains on track and budget for first gold pour in calendar Q4 2025;
• The Kiniero project remains LTI free (lost-time injury) with 4,857,704 hours complete to Sept. 30, 2025;
• Mine development activities are tracking according to plan; mining has commenced on day-and-night shift with delivery of ore to the run-of-Mine (ROM) pad;
• Drilling and blasting contractor mobilized to site, with the first blast planned this month;
• Construction of the tailings storage facility is progressing on schedule;
• Field erected tankage is 99 per cent complete, with only painting outstanding;
• Oxide crusher ROM wall and power station remaining footings were poured in early October;
• Concrete contract is complete and demobilization commenced;
• All project fabrication materials platework, steelwork, piping and electrical materials have arrived at site;
• SMP (structural, mechanical and piping) works progressing, with 50 per cent of structural steel erected/preassembled;
• SAG (semi-autogenous grinding) and Ball mill assembly of major components is nearing completion;
• Power station is progressing on schedule; low-voltage motor control centres (LV MCCs) received and installed;
• Fuel storage facility tankage erection progressing on schedule.

Robex's managing director and chief executive officer, Matthew Wilcox, said: "We are getting to the tail end of construction at Kiniero as we look towards first gold by the end of [calendar year] 2025; it is pleasing to see the continued efforts and dedication of our teams to complete this project safely while meeting our time and budget considerations.

"Mining is now under way, with delivery of ore to the ROM pad and drilling and blasting set to commence shortly. Major components of the process plant have taken shape and are nearing the commissioning phase, which is scheduled to commence next month.

"As we finalize construction, we continue to see great examples of teamwork across the different areas of the project. I am really proud of what we have achieved to date at Kiniero and what is ahead for Robex in the next few months as we achieve first gold and ramp up to full production."

Kiniero development activities

Construction and development works at Kiniero continue to track well against the schedule.

Mining operations have commenced on day-and-night shift, with 82,590 tonnes material mined, including 20,625 tonnes of ore. An additional 10,000 tonnes of ore were rehandled from historical stockpiles to the main ROM pad.

The operations readiness team has commenced mobilizing to site and, together with the commissioning team to be mobilized early November, the project is well positioned for gold pour in calendar Q4 2025.

Grade control drilling is still progressing, with 66,105 metres drilled at Sabali South covering the entire starter pit, with a further 16,070 metres drilled at Sabali North and 61,506 metres drilled at Mansounia. Grade control drilling results at Sabali South closely tracked the mineral reserve model. Results confirm the robustness of the geological model and support short-term mine planning.

Concrete works for the process plant and power station are complete. All structural steel, platework, piping and electrical material have now arrived at site, and the process plant will quickly transform as construction is accelerated.

Process water and event pond earthworks have been complete and ready for lining.

The SAG mill assembly is complete, and the mill has been floated on the bearings and the ring gear has been installed. The next step is to align the ring gear and install the pinion and drivetrain. The ball mill assembly is almost complete, with the ring gear installation to be complete next week.

Primary crushing and reclaim are well advanced with steelwork and platework installation. Conveyor steelwork is being preassembled and erected.

The construction of the leaching circuit is advancing ahead of schedule, with all intertank screens installed and five of the six agitators installed on Train A, with cable and piping installation to commence next week.

Steelwork for the elution, gold room and reagents is also progressing well.

The on-site pipe fabrication workshop has been set up, and prefabrication of piping is under way.

The electrical team is fully mobilized on site, with major advancements made on the power station, process plant and high-voltage distribution within the process plant. The power station is 45 per cent electrically complete, with nearly 30,000 metres of cables installed. The low-voltage motor control centres (MCCs) have been received at site and placed in position.

The power station is progressing well, with all ancillary equipment delivered and installed. Engine haul building steelwork is complete, with cladding outstanding. The power station is on track with four four-megawatt engines delivered to site; preparation of the base frames has commenced, with the engines to be installed in the coming weeks and planned to run on diesel by mid-November. The power station control room electrical equipment is all installed, with energization for commissioning of radiator fans, pumps and compressors planned for next week.

Overland piping, including the tailings pipeline and fresh water pipeline, is advancing well, with more than 15 kilometres welded.

The tailings storage facility (TSF) is progressing well, with the eastern embankment 76 per cent complete, with 529,195 cubic metres of fill placed. The lining crew has remobilized to site and has installed a further 78,650 square metres of liner during the past week.

Next steps:

• Continue with SMP works for the process plant and power station;
• Complete mill installation;
• Continue with electrical and instrumentation installation in a staged approach to allow energization of switch rooms for commissioning in November;
• Complete the installation of four engines and commence commissioning and run on diesel by mid-November;
• Continue with tailings storage facility earthworks and lining;
• Complete mobilization of operations, operation readiness and commissioning teams; complete recruitment of operators and commence training programs;
• Continue with mining development works and ramp up mining with more ore delivered to the ROM pad;
• Continue grade control drilling at Sabali pit.

Robex remains very well positioned to advance the construction of Kiniero, which remains on schedule to realize first gold production by calendar Q4 2025.

We seek Safe Harbor.
