PRESS RELEASE – SEPTEMBER 17, 2018

RIO2 LIMITED

CORPORATE UPDATE

Rio2 Limited (“ Rio2” or the “ Company”) (TSXV: RIO; BVL:RIO) is pleased to provide a

Corporate Update.

CHANGE OF PROJECT NAME AND CHILEAN SUBSIDIARY NAME

Rio2 has chosen to change the name of the Cerro Maricunga Gold Project to the Fenix Gold

Project and the name of the Company’s Chilean subsidiary from Minera Atacama Pacific

Gold Chile Limitada to Fenix Gold Limitada. The reasons for the name changes are to simplify

Guatemala, Panama, Ecuador and Brazil.

Mr. Garay obtained his degree as a Geological Engineer from Universidad Nacional de

Ingenieria, Peru and has a M.Sc. in Mineral Exploration from Queens University, Canada.

FENIX GOLD PROJECT – ACTIVITIES UPDATE

Staged Development Strategy

To date, the Fenix Gold Project has been envisaged as a heap leach gold mining project that

will involve open pit mining of mineralized material, three stage crushing, no agglomeration

and cyanide leaching of gold. For details of this plan see Atacama Pacific Gold Corporation’s

independent technical report entitled “NI 43-101 Technical Report on the Cerro Maricunga

Project Pre-Feasibility Study Atacama Region, Chile” dated October 6, 2014 with an effective

date of August 19, 2014, a copy of which document is available on SEDAR under Rio2

Limited’s SEDAR profile at www.sedar.com.

Based on Rio2’s findings in the Pre -Feasibility Study, Rio2 is planning to revis e the

development of the Fenix Gold Project and produce a Feasibility Study which is scheduled for

completion in H2, 2019, outlining the revised development plan.

The current thinking is focused on a staged development plan which will focus on mining

higher-grade mineral reserves in the early years of production followed by a steady

expansion of production to an optimal throughput rate with the aim of maximizing free cash

flow that is generated by the project. The Company believes that a staged approach to

developing the Fenix Gold Project will allow for upfront capital expenditures to be minimized

and will make financing simpler with cash flow from operations to be utilized to fund project

expansion.

Revised Mineral Resource Estimate

In preparation for t he completion of a Feasibility Study on the Fenix Gold Project, Rio2 is

planning to produce a revised resource estimate for the deposit to be completed by the end

of the Q1, 2019. To assist with producing the new resource estimate, the Company’s

geologists under the direction of Mr. Garay are currently re -logging the existing core from

past Fenix drilling programs dating back to 2010. The principal reason for re -logging the

core is to generate, for the first time, a geological model that will support the new resource

estimate. The Company geologists believe that there is a high -grade component to the

resource related to structures and breccias which are prevalent in the deposit but have not

been defined in the current resource estimate which has been constra ined by a 0.15 g/t

grade shell without considering geological domaining. The Company’s geologists are also

resampling surface exposures of the mineralized resource to include this information in the

revised resource estimate. Previous surface sampling was not included in the current

resource estimate despite a high proportion of samples being above the average

mineralized resource grade and the resource outcropping at surface.

The Company is also planning to commence a 7,000 -meter drilling program in Novem ber

2018, focused on the US$ 728 pit shell defined in the Pre-Feasibility Study. The objective of

this drilling is to intersect and define east-west structural feeders that the geologists believe

are controlling the near surface higher grade mineralization. The drilling will also serve as a

check for previous drilling within the US$ 728 pit shell and assist in better defining the near

surface higher grade mineralized component of the new resource estimate.

Feasibility Study Engineering Activities

A series of geometallurgical, geotechnical and condemnation drill holes will also be

undertaken to follow on from the in -pit drilling program. Metallurgical drilling will assist the

Company on completing a trade -off of various crushing options for the project whil e

geotechnical drilling will focus on pit wall stability and condemnation drilling will be targeted

in areas of mine infrastructure such as leach pad, waste dump, process plant and other

mine facilities. All the information gathered from this additional drilling will contribute to the

completion of the planned Feasibility Study.

Water Supply Options

Rio2 has a water supply agreement in place with Aguas Chañar S.A. for the purchase of 2.5

million cubic meters (80 litres per second) of treated industrial water annually. The term of

the agreement is for 13 years and commences upon the start of production at the Fenix

Gold Project. Aguas Chañar S.A. is a company jointly owned by Aguas Nuevas S.A. (a

subsidiary of Marubeni Corp) and a private Chilean investment fund, Toesca Asset

Management. The company owns and operates a water treatment facility in the City of

Copiapo located approximately 140 kilometers west of the Fenix Gold Project. Rio2

anticipates that the use of industrial water will simplify the permitting process for the

development of the Fenix Gold Project as water required for the project will not be extracted

from underground water sources as typically is the case in most Chilean mining projects.

The current plan is to build a pipeline with associated power line from the Aguas Chañar

facilities to Fenix which is likely to be constructed along the existing main road from Copiapo

to Argentina which passes within 20 kilometers of Fenix. The capital costs, operating costs

and cost of water for this water solution have been incorporated into the Pre-feasibility Study

NI 43-101 Technical Report on the Cerro Maricunga Project Pre-Feasibility Study with

effective date, August 19, 2014.

As Rio2 is considering a staged development strategy for the Fenix Gold Project, water for

the contemplated starter project is likely to be in the range of 15 to 25 litres per second

depending on throughput. To satisfy the amount of water required and to accelerate the

time to Stage 1 production, the Company is reviewing a number of water options involving

unused water rights in the proximity of the project.

Environmental Activities

From an environmental perspective, the Company has recently commenced activities

related to completing an environmental baseline study on the Fenix Gold Project. Depending

on the ultimate water source that is selected for the starter project, it is currently estimated

that the baseline study will be completed by mid 2019 and an Environmental Impact Study

filed thereafter for the review and approv al by Chilean Environmental Authorities. The

Company is also in the process of completing a social baseline study as a precursor to

engagement and dialogue with all stakeholders within the area of future development of the

Fenix Gold Project.

CORPORATE ACTIVITIES UPDATE

Rio2’s leadership team has begun repositioning the Fenix Gold Project as a new, gold

development stage project in the precious metals sector. Since closing the acquisition of

Atacama Pacific Gold Corp., numerous meetings have been held wit h a broad range of

investment bankers and mining analysts with the objective of raising awareness of Rio2 and

its new project. To that end, an analyst visit to the Fenix Gold Project has been coordinated

for later this month and members of the Executive Management team will also be attending

the Denver Gold Forum in Colorado Springs. News flow is expected to increase during the

next 18 months as the Company completes its planned drilling program, updates the

mineral resource estimate, completes additional e ngineering work, files an Environmental

Impact Study and completes a Feasibility Study on the project.

Alex Black, President and Chief Executive Officer of Rio2, stated, “The Rio2 management

team is keenly focused on advancing the Fenix Gold Project to pr oduction and a number of

activities will be completed during the next 18 months that will demonstrate how we intend

to achieve our objective. Once we have completed the Feasibility Study we will be able to

outline a detailed project schedule which will provide project timing and key milestones.”
