RIO2 DESIGNATES PROCESS PLANT CONSTRUCTION AND CIVIL CONTRACTORS

FOR THE FENIX GOLD PROJECT

For Immediate Release SEPTEMBER 28, 2020

Rio2 Limited (“Rio2” or “the Company”) (TSXV: RIO; OTCQX: RIOFF; BVL: RIO) today announces that it

has taken another key step towards the development of its Fenix Gold Project (“the Project”) located

in Chile by selecting the following lead contractors:

 Process plant / site infrastructure construction contractor - HLC Ingeniería y Construcción (“HLC”)

 Leach pad and civil design contractor - Anddes Asociados S.A.C. (“ANDDES”)

 Civil earthmoving and construction contractor - STRACON S.A. (“STRACON”)

Together with Rio2, the companies have executed an early contractor involvement agreement (“ECI

Agreement”) for early works associated with the process plant / site infrastructure, leach pad and

project civil design and construction. Prior to the signing of this ECI Agreement, the parties have been

working exclusively over the past few months in close cooperation with Rio2 management to detail

all project engineering items related to the construction of the Fenix Gold Mine. Detailed engineering

activities fo r the construction of the Fenix Gold Mine are scheduled to be completed in early

November in preparation for project financing.

The scope of works for each contractor includes the following:

HLC - design and construction of the primary crushing and stockpile circuit, ADR plant and

water facilities, lime dosing and leach pad pumping circuit, workshop, warehousing, onsite

offices and dining facilities, onsite power generation and distribution.

ANDDES - engineering design for all civil earthworks, including access roads, water controls,

infrastructure platforms, leach pad and ponds, waste dump and stockpiles. ANDDES will also

provide site-based supervision of all civil works including quality control and assurance.

STRACON - responsible for all earthmo ving and associated activities, all road maintenance

and construction, building and infrastructure platforms, pad and pond construction, waste

dump and stockpile preparation, water controls, water transport for construction purposes

and various support ser vices to HLC and ANDDES as required. These services will be in

addition to their role as lead mining contractor as announced and outlined in a previous press

release dated July 7, 2020.

The commercial terms of the above mentioned contract services wi ll utilize an alliancing -style

commercial framework based on the project configuration, mine plan, methodologies and

productivity estimate assumptions contained in the Fenix Gold Project Pre- Feasibility Study with an

effective date of August 15, 2019 a copy of which document is available under Rio2’s SEDAR profile at

www.sedar.com.

The Fenix Gold Project continues to advance as scheduled and first gold production is estimated for

late H2, 2022.

Rio2 is also pleased to report that the Fenix Gold Project has been recently included in a selected list

of 220 multi-sector projects to be prioritized by the Office of Sustainable Project Management (GPS)

- part of the Chilean Ministry of Economy. This governmental office helps prioritize development

projects that are perceived as environmentally responsible and sustainable and also respectful of their

surrounding communities.

MINE AND INFRASTRUCTURE CONSTRUCTION ALLIANCE

The basis for Rio2 establishing a mine and infrastructure construction alliance with HLC, ANDDES and

STRACON at the Fenix Gold Project is a best for project business strategy. Together with the three

contractors, the Rio2 management team collaborated, implemented and executed with this same

approach when they built the La Arena and Shahuindo gold mines in Peru with Rio Alto Mining Limited.

In the case of the Fenix Gold Project mine and infrastructure construction alliance, Rio2, HLC, ANDDES

and STRACON will work together as an integrated team, dedicated to exceeding goals, controlling

budgets and adding value through exceptional performance while working in a safe and

environmentally sustainable manner focused on every detail of the construction process. The alliance

will implement an inclusive social policy as a priority based on the hiring of local personnel and service

companies from Copiapó and the Atacama Region.

The principal characteristics of a successful alliance are;

• collective responsibility;

• collective sharing of risks and opportunities; and

• no fault, no blame philosophy leading to no disputes between the owner and contractors.

The payment model of an alliance includes;

• reimbursement of 100% of contractor’s project costs plus a fee (corporate overheads and

profit);

• a KPI based regime that rewards for outstanding performance and penalizes poor

performance; and

• unanimous, best for project, management and decision making and the selection of an

integrated owner/contractor team on the basis of best person for each position and avoiding

duplication of roles.

Benefits of an alliance;

Both owner and contractors work together to:

• achieve project objectives by aligning the commercial framework and objectives of the

participants;

• collectively manage project issues and risks;

• collectively own the project risks, and outcomes;

• encourage a collaborative, flexible approach to the management of the project;

• ensure a strong focus on collaboration to achieve win-win solutions;

• manage the project with open book transparency of all costs providing the owner confidence

in the robustness of both the estimate and actual cost outcomes;

• focus on achieving outcomes rather than exchange of contractual dispute letters; and

• eliminate the duplication of resources.

Alex Black, President & CEO of Rio2, stated, “The signing of this ECI Agreement with HLC, ANDDES and

STRACON forms another key part of Rio2’s strategy to prepare for next years’ construction phase of

our Fenix Gold Project. The Rio2 management team is plea sed to work again with HLC, ANDDES and

STRACON, this time in Chile, and look forward to further optimizing the mining and construction

solution for the Project in preparation for next years’ construction program. With only a handful of

new gold mining proj ects entering into construction next year, Rio2’s Fenix Gold Project is set to

become a notable and impactful Latin American gold producer in 2022.”
