RIO2 Reports ON Fenix GOLD MINE Progress

Corporate Updates

RIO2 REPORTS ON FENIX GOLD MINE PROGRESS

For Immediate Release December 16, 2024

Vancouver, BC - Rio2 Limited (“Rio2” or the “Company”) (TSXV: RIO; OTCQX: RIOFF; BVL: RIO), after

completing the Company’s highly successful debt and equity financing announced on October 21,

2024, provides an update on the progress made by its Chilean subsidiary, Fenix Gold Limitada (“Fenix

Gold”), which is currently constructing the Fenix Gold Mine located in the Maricunga Gold Belt of the

Atacama Region, in Chile. Advancements include the commencement of hiring of our Chilean

workforce, mobilization of civil construction and plant construction contractors, completion of civil

works for the processing plant site and commencement of construction of the heap leach pad and

adjoining PLS pond. The Company has also entered a fixed price contract totaling US$49M (plus GST)

with its plant construction contractor, HLC Chile SPA, for the construction of the Fenix Gold Mine

adsorption, desorption, and gold recovery (“ADR”) plant, associated infrastructure and site electrical

distribution lines. Long lead items such as gensets, principal pumps, and electrical switchgear facilities

have been purchased directly by Fenix Gold. Rio2 will provide guidance in January 2025 for the

construction schedule and associated budget, along with a projection of when the first gold

production is expected to be achieved.

Andrew Cox, President & CEO, commented, “Since closing our debt and equity financing in October,

we have made excellent progress on all fronts related to the construction of our Fenix Gold Mine. The

execution of the mine built on our proven alliance approach with our civil contractor and plant

contractor is progressing as planned and the negotiation of a fixed price contract for the plant

construction is a positive bonus to managing and controlling our construction budget. We are

extremely happy to see the positive impact that we are making to employment in the Atacama Region

and look forward to providing regular quarterly updates through construction in 2025.”

IMPLEMENTATION OF SAP S/4HANA CLOUD

Rio2 also announces that it has selected the GROW with SAP solution for Enterprise Resource Planning

(“ERP”) and Syntax as its implementation partner. This ERP software solution will be used by Rio2 to

manage our core business processes, including finance, human resources, supply chain and

procurement, all within a unified view of activity and single source of information. The Grow with SAP

solution will help streamline business operations by centralizing data across different departments

and disciplines, allowing for better decision making and improved efficiency.

Syntax will work with Rio2 to implement SAP S/4HANA Cloud through GROW with SAP. Rio2 selected

Syntax as its implementation partner due to our confidence in Syntax’s ability to execute the

implementation successfully, as well as Syntax’s significant expertise in and understanding of the

mining industry.

“Digital transformation is not a nice-to-have; it’s necessary for successfully operating in today’s mining

industry,” said Michelle Smith, Vice-President, Syntax Mining Practice, “Syntax is proud to work with

Rio2 to streamline processes, enhance data visibility, and enable smarter decisions while accelerating

their transformation journey.”

The implementation of SAP S4/H ANA Cloud will support Rio2 at the mine site and in its corporate

offices. On-site, SAP S/4 HANA Cloud will support the operations team during the construction of the

Fenix Gold Mine and afterward when Fenix is in production; off- site, the implementation will allow

Rio2’s corporate offices to analyze vital data, as well as optimize financial reporting. The Company is

targeting a “go-live” of SAP S/4HANA Cloud in Q2 2025.

“As we move towards the next phase of our Company with the construction of the Fenix Gold Mine,

we are really excited about the implementation of SAP S/4 HANA Cloud. It’s a scalable solution that

will grow alongside us, improving both our operations and finance functions,” says Kathryn Johnson,

EVP – CFO and Corporate Secretary. “We are also pleased to be working with Syntax on this project.

We felt that Syntax’s long -standing experience and reputation for excellence working with mining

companies across Canada, the US, and globally made them a great match for our business.”

Rio2 is familiar with SAP® capabilities, as its mining contractor also leverages SAP® tools in its business

activities. This existing synergy between Rio2 and its mining contractor should result in increased

efficiency, reducing costs and directly contributing to operational effectiveness.

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 on and designed in 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 and will generate employment

for at least 1,200 people during the construction phase and 550 people during the 17-year operations

phase. The mine being contemplated at the Project 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.

The scientific and technical content of this news release has been reviewed, approved and verified by

Ronoel Vega, Min. Eng., MMBA, FAusIM M, who is a QP under NI 43-101. For additional information

regarding the Project, including key parameters, assumptions and risks associated with its

development, see the independent technical report entitled “NI 43-101 Technical Report on the

Feasibility Study for the Fenix Gold Project” (the “Feasibility Study”) pursuant to National Instrument

43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”). The Feasibility Study is dated

October 16, 2023, with an effective date of October 16, 2023, a copy of which document is available
