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".

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 688km² land package to 996km², a 45% increase (+308km²). This increased land package provides additional exploration potential in the Tapajos region for a total of 996km².
