RIO Rio2 Limited New

Rio2 Limited (“Rio2” or the “Company”) (TSXV: RIO; OTCQX: RIOFF; BVL: RIO), is providing an update on construction activities at its Fenix Gold Mine located in the Maricunga Gold Belt of the Atacama Region, in Chile.

OVERVIEW

Pre-construction activities commenced at the Fenix Gold Mine in 2022 prior to the Environmental Impact Assessment (“EIA”) for the project being rejected by the Chilean environmental regulators. Those activities included:

• ordering and securing of long lead items for the construction of the adsorption, desorption, and gold recovery (“ADR”) plant and associated infrastructure
• fabrication of ADR plant components such as tanks and ADR plant foundation footings
• construction of a 565-person camp and associated mess and office facilities at the Lince infrastructure site, located 20km from the mine site
• water loading facilities at the Nueva Atacama water treatment facilities located in Copiapo

The project’s EIA was subsequently approved in December 2023 following a successful 18-month appeal process.

The Company recommenced construction activities at the Fenix Gold Mine in October 2024 after successfully completing a debt and equity financing for the construction of the mine announced on October 29, 2024.

The projected construction capex for 2025 is estimated to be USD 122 M (excluding Chilean VAT tax which is refundable) with construction expected to be completed in November 2025. First gold production is currently guided for January 2026.

PLANT SITE

Bulk earthworks at the plant site have been completed and concrete bases for the footings of the processing plant have been poured. The ADR plant will be housed within a steel framed building cladded with modular thermo-acoustic panels.

LEACH PAD

Earthworks have commenced on the leach pad stability platform, which forms the base of the Phase 1 leach pad. The leach pad has been designed to be built in four phases over the 17-year mine life of the 20,000 tonnes per day operations.

PREGNANT LEACH SOLUTION (“PLS”) POND

Excavation earthworks for the PLS pond have commenced adjacent to the ADR plant. The PLS pond will be lined with a double HDPE geomembrane liner system and have an installed capacity of 28,000 cubic metres. As determined by water balance modelling in the 2023 Fenix Gold feasibility study, a larger major events pond is currently planned to be built in year 6 of the mine operation.

PERSONNEL

The recruitment activities for the Fenix Gold Mine have focused on hiring key personnel for construction activities and future mine operation roles. Personnel numbers at the Fenix Gold Mine are increasing and, currently, over 531 staff and contractors work on-site. At the end of Q4 2024, approximately 50% of the workforce were from the Atacama region, and 16% of on-site personnel were women.

SAFETY

At the end of Q4 2024, the project achieved 161,917 person-hours worked with no lost time injuries reported.

GRADE CONTROL DRILLING AND GEOPHYSICAL SURVEY

In February, the Company will commence a 12,000m grade control drilling program focused on the first three years of production planned from the Fenix South and Fenix North pit areas. Fenix South will be the first area drilled during the months of February, March and April, and Fenix North will be drilled in October and November. The Fenix South pit will be the principal source of ore for the first year of mine production.

From February to March the Company will complete a survey of 25,000 meters of CSAMT electromagnetic lines. This survey will help the geological team identify silicified zones associated with black banded veins, which are the main gold host at the Fenix Gold deposit. The geophysical targets generated from this work will allow the Company to focus its future exploration drilling campaigns with the objective to grow the mineralized resource at Fenix Gold. Resource expansion drilling is currently planned to occur once gold production has commenced at the mine.

Rio2 is also pleased to announce that Enrique Garay has recently returned to the Company as Senior Vice President - Geology to lead and oversee the Fenix Gold geological team in preparation for mining toward the end of 2025 and future exploration.

MINE EXPANSION STUDY & ASSOCIATED EIA

A preliminary internal study completed by the Rio2 technical team has indicated that the Fenix Gold Mine has the potential to be expanded from its first phase 20,000 tonnes per day ore mining rate to around 80,000 tonnes per day. Increasing the ore mining rate to this level could see gold production rise from an initial rate of approximately 100,000 oz per annum to a target range of 250,000 – 300,000 oz per annum. To quantify and justify this potential expansion, the Company has initiated a mine expansion study with a target completion date by the end of 2025. Long-term water options will be assessed for the study and the most optimal water strategy will be selected and form a base case for project economics. To put this potential expansion case on a fast track to a construction decision, Rio2 has recently initiated baseline studies for an EIA study on the project, which is anticipated to be ready for review by the environmental regulators in the Atacama Region by Q4 2026. As most of the required infrastructure for the expanded project (apart from water which is expected to be provided by a third-party provider) is within the existing footprint of the currently approved EIA, the Company expects the EIA process to advance relatively smoothly. Updates will be provided as the expansion study and EIA progress.

Andrew Cox, President & CEO, commented, “Site activities at the Fenix Gold Mine continue advancing to plan. We are delighted with the team we are putting together and the milestones achieved so far. We look forward to continued success as we prepare the mine for first gold production in January 2026.”

STOCK OPTION GRANT

The board of directors of the Company has approved the grant of an aggregate of 6,310,000 incentive stock options (the “Options”), pursuant to the Company’s Stock Option Plan, to a total of 72 directors, officers and employees of the Company, its Peruvian subsidiary, Rio2 S.A.C., and its Chilean subsidiaries, Fenix Gold Limitada and Lince S.A. The Options are exercisable at a price of $0.70 per share (based on a 10% premium over the closing price of C$0.63 on January 10, 2025) and will expire five years from the grant date. The Options represent the Company’s annual grant of long-term incentives consistent with the Company’s regular yearly compensation.

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 550 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.
