BROSSARD, QC, May 26, 2022 – G Mining Ventures Corp. (“GMIN” or the “ Corporation”) is pleased to

provide an update on key developments on its 100% owned Tocantinzinho Gold Project (“ TZ” or the

“Project”). Additionally, GMIN is pleased to announce the appointment of key staff members as the

Corporation looks to execute on its objective of advancing the Project towards a construction decision in

H2-22.

Louis-Pierre Gignac, President & Chief Executive Officer, commented: “GMIN is advancing the TZ project

with a comprehensive early works program, including commencement of detailed engineering, the start of early-

stage construction activities including upgrades to the camp and to the surrounding infrastructure, procurement

of long lead items, establishment of a logistics base, and planning for access road improvements. We are very

pleased to add a number of talented and experienced staff to the GMIN team, many of the individuals being

familiar faces from past projects. We have assembled an exceptional team to continue the advancement of TZ into

one of the biggest primary gold mines in Brazil, with commercial production targeted to commence in the second

half of 2024.”

Tocantinzinho Development Update

Since the release of the TZ Feasibility Study (as detailed in the press release dated February 9, 2022) the

Corporation has advanced development of the TZ project on several fronts.

Health & Safety

Year to date, a total of 71,060 hours has been worked without any lost time incident. The health and safety

of employees, contractors and other stakeholders is at the forefront of the Corporation’s values and

objectives.

Labor Agreement

GMIN has agreed in-principle to a new collective bargaining agreement with the local mining union,

Sindicato dos Trabalhadores nas Indústrias de Extração e Beneficiamento de Minérios Ferrosos e não

Ferrosos dos Estados do Amapá e Pará. The agreement will take effect on August 1 st, has a term of two

years, and is intended to cover the construction phase as well as the initial phase of operation. The

agreement will enable the implementation of a 2 week-on / 2 week-off roster schedule for the Project, and

establishes the details of the benefits packages.

Human Resources and Employee Training

The team has grown and expanded with the increased level of activity on site. At the time of the TZ

acquisition, the Project team had 15 employees, which has now grown to 42, with the additional hirings

focused on Supply Chain, Human Resources, Environment, and Health & Safety. Job fairs were held in our

neighboring communities of Itaituba, Moraes Almeida and Novo Progresso that resulted in exceptional

turnouts, with over 500 resumes collected, and hundreds of first interviews conducted.

Training programs have been initiated in collaboration with the National Industrial Training Service

(“SENAI”), the largest institution of professional and technological education in Latin America. SENAI is a

network of not-for-profit secondary level professional schools established and maintained by the Brazilian

Confederation of Industry (a patronal syndicate), making SENAI one of the most important institutions in

the country providing formal training for specialized workers. The first set of classes is geared toward

construction personnel. Additionally, a mine equipment simulator was purchased and mobilized to start

training and help with the recruitment process for mobile equipment operators.

Execution Strategy – The “Self-Perform” Approach

Project execution will be through the G Mining Services (“ GMS”) “Self-Perform” approach, an integrated

team strategy that provides an overall lower risk approach, and allows for better site coordination, initiative

on potential cost and schedule efficiencies and, ultimately, better project delivery and transition to

operations. GMIN will not seek a fixed price Engineering, Procurement and Construction Management

contract (commonly referred to as “ EPCM”) for the Project’s mill and major facilities. Whereas EPCM

providers may outsource and manage multiple sub-contractors, GMIN will execute the project in-house. By

fully controlling logistics, directly purchasing equipment, and directly hiring labor, the approach will help

keep project teams focused and overhead costs minimal, particularly through the elimination of costly “scope

changes”.

Aspect Self-Perform Approach EPCM Approach

Project Team

/

Responsibility

• Project owner hires GMS, brings key personnel on

the payroll, and integrates the personnel with their

internal project team, effectively combining to

create an in-house team

• Project owner remains the project manager as GMS

personnel become internal employees

• Project owner hires external engineering firm to be

the project manager

• Project owner establishes internal project team to

manage and oversee the EPCM firm

Engineering

• GMS completes engineering and assumes

coordination in-house by adding the required GMS

personnel to the in-house team as needed

• QA/QC performed by third parties

• EPCM firm performs engineering or outsources to

third party engineering firms

Procurement

• Direct purchase of equipment and materials on a

global scale

• Central management of supply chain with

management of logistics to site

• Some procurement management by EPCM firm

• Procurement is also done by contractors,

depending on EPCM package

Construction

• GMS (acting as the project owner) executes

construction of all aspects of project with exception

of certain scope items awarded to local contractors

• Direct hiring of expatriate and local work force

reduces mark-ups, GMS transfers key employees to

construction team for duration of project

• Construction performed by contractors as per

engineering approved drawings

• Each contractor has predefined scope where each

contractor has its supervision and overheads

Management

• Project team manages personnel, schedule and

costs

• Project team manages services such as construction

camp and employee transportation

• External engineering firm establishes a small project

team to manage external contractors

• Management of scope changes and extras

Power Supply Agreement

Brazil’s national grid operator, Operador Nacional do Sistema Elétrico (“ONS”), has confirmed the availability

of 22.9 megawatts (“MW”) of power supply requested by GMIN. ONS is the government agency responsible

for the coordination and monitoring of electric power generation and transmission facilities connected to

Brazil’s national grid, where 84% of installed capacity is from renewable resources, mainly hydropower.

Negotiations on final pricing are progressing with three shortlisted contractors for the construction of the

191km power transmission line. When the construction decision for the transmission line is made, the

strategy will be to execute on multiple fronts, potentially with up to two contractors. The construction of

the transmission line is the main scope of the Project that will be outsourced and thus not executed using

the Self-Performed approach.

Project Expenditures

Procurement activities are currently focused on long lead items, with firm prices being finalized with selected

suppliers. Several major mechanical and electrical packages are under final review and in line with the

budgetary quotes from Q4-21 used in the DFS. Total project commitments and expenditures are expected

to total $47 million by the end of June.

Expenditures and commitments include:

 1200-person permanent camp facility sourced from local Brazilian suppliers;

 Grinding mills (SAG & ball) from Metso Outotec;

 Partial purchase of the primary mining fleet from Grupo Sotreq, the local Brazilian Caterpillar dealer;

 Drilling equipment from Sandvik Group;

 Support equipment such as pickup trucks and service trucks; and

 Concrete batch plant.

Construction – Early Works Activities

Expansion of the exploration camp, which will support initial construction activities, is in progress and

includes additional sleepers, a kitchen expansion, an additional water well, as well as sewage and power

generation. The expanded exploration camp will have capacity for 350 individuals, and is to be completed

by the end of July. Access road improvements to drainage and road surfacing is being initiated at this time

as well. A freight forwarder logistics base is being established in Moraes Almeida, which will provide storage

and consolidation area for equipment and materials moving to site especially during the early stages of the

project.

Regional Exploration Upside

Agência Nacional de Mineração (known as “ ANM”), the Brazilian federal mining agency, has granted the

renewal of several exploration licenses, some outside of the immediate project area, resulting in an

expansion of the existing 688km 2 land package to 996km 2, a 45% increase (+308km 2). This increased land

package provides additional exploration potential in the Tapajos region for a total of 996km 2.
