     RIOFF    +6.21%  
     GC=F    +0.95%       VANCOUVER, British Columbia, Oct. 29, 2025 (GLOBE NEWSWIRE) -- Rio2 Limited (“Rio2” or “the Company”) (TSX: RIO; OTCQX: RIOFF; BVL: RIO) today provides an update on progress made at Rio2’s 100% owned Fenix Gold Project (“Fenix Gold” or “the Project”) currently under construction in the Atacama Region, Chile. At the end of Q3 2025, construction was 63% complete and remains on track and on budget for first gold production in January 2026.
    
    Construction  highlights for the eleven-month period from November 1, 2024, to 30  September 2025, are as follows, with all amounts expressed in US  dollars:
    Health & Safety –  A total of 1,865,791 person-hours have been worked on the Project to  date, with 3 Lost Time Incidents recorded (a finger injury in Q1, a  dislocated ankle and a Back Strain in Q3), resulting in a Lost Time  Incident Frequency Rate (LTIFR) of 1.61. The Total Incident Frequency  Rate (TIFR) for the Project as of September 30, 2025, was 8.58.
    Budget – Total  spend to date since November 2024 of $86.7 million for works completed,  vs budget of $86.6 million. These costs exclude corporate overheads and  pre-construction costs expended in 2022.
    Schedule –  Total Project is currently 63% complete, and we expect to achieve first  gold production in January 2026. All long lead time procurement items  are in hand.
    
    Construction Progress
    As  of the end of Q3, 12.7 hectares of geosynthetics were installed on the  leach pad. This area guarantees a leach pad for six months of production  capacity. Leach pad construction recommenced in October 2025, with an  additional 10 hectares of leach pad capacity expected to be delivered by  the end of the year.
    We have placed  approximately 22,000 m3 of overliner material on the leach pad, covering  approximately 8.5 hectares of geosynthetic material ready to receive  mineral.
    Mining of ore from haul road  excavation work from Fenix Central and Fenix South stater pit area began  in August and continues, with 87,000 tonnes of ore placed onto the  leach pad, during Q3, with an average gold grade of 0.45 g/t, equating  to 1,260 oz placed on the leach pad ready for plant commissioning in  December/January.
    
    The  PLS (Pregnant Leach Solution) pond is now complete and ready for  hydrostatic testing. Water trucking commenced in late September, with  the aim of filling the PLS pond by mid-November for leaching circuit  commissioning.
    Construction of Haul Road 1 is  now complete, while Haul Road 4 is largely complete with only some  minor finishing works required. The Fenix South orebody is now connected  to the leach pad via the designed haul roads.
     Related  to the ADR (Adsorption, Desorption, Recovery) Plant, diesel generators  and all three electrical switchgear rooms have been installed. Reactors  for chemical reactivation (Acid Wash) and Desorption have also been  installed. Ongoing works include the installation of the adsorption  circuit piping and electrics, barren pump station, reagent handling and  chemical reagent storage facilities. Gold Room construction and  implementation of electrowinning, retorts and furnace are also underway.
  Human Resources –  a total of 1,521 personnel (including contractors) are currently  employed at the Project. 94% of the workforce is comprised of Chileans,  with 44% from the Atacama Region and 13% are female.
  Exploration –  Grade control drilling activities at Fenix South were completed in late  July and the internal reconciliation of the MRE for Fenix South will be  concluded in October. Preliminary analysis of this work indicates a  very close reconciliation (tonnes and grade) of the grade control model  to the reserve model.

     FENIX GOLD PROJECT
  The  Fenix Gold Project is one of the largest undeveloped gold oxide, heap  leach projects in the Americas, hosting a Measured and Indicated mineral  resource (as such term is defined in National Instrument 43-101  -Standards of Disclosure for Mineral Projects, “NI 43-101”) of 4.8  million ounces of gold which the Company believes will make a positive  contribution to the Atacama Region and Chile. The Project is an example  of modern gold mining where a full complement of technical,  environmental, and social considerations has been consulted and designed  from the outset. The Project represents a significant investment in the  gold mining business in Chile by a junior mining company of  approximately US$235M of initial and sustaining capital, generating  employment for at least 1,200 people during the construction phase and  800 people during the 17-year operations phase. The mine being  contemplated will be a run-of-mine heap leach operation; no crushing or  tailings storage facilities are required, thereby minimizing the overall  impact and footprint of the Project.
