G Mining Ventures Announces Formal Construction Decision for Tocantinzinho Gold Project and Provides Project Development Update

  • Positive construction decision approved by the Board of Directors on Tocantinzinho Gold Project
  • Extension to key installation licenses received
  • Advancing procurement and commitments for long lead items, with $136 million committed to date (29% of total) in line with budget, with detailed engineering 30% complete
  • Early works activities completed on time and on budget with no lost time incident
  • Appointment of Mathieu Gignac as Project Director, Julie-Anaïs Debreil as Vice-President Geology & Resources, and Eduardo Leão as Sustainability Manager

BROSSARD, QC / ACCESSWIRE / September 12, 2022 / G Mining Ventures Corp. ("GMIN" or the "Corporation") (TSXV:GMIN) (OTCQX:GMINF) is pleased to announce that its Board of Directors has made a formal decision to proceed with the construction of the Tocantinzinho Gold Project ("TZ" or the "Project"). Additionally, GMIN is pleased to provide an update on developments on the Project, including the receipt of essential installation license extensions, recruitment, engineering, procurement, early works activities, and the appointment of additional key personnel.

Louis-Pierre Gignac, President & Chief Executive Officer, commented: "GMIN was reorganized in October 2020 with the objective of building the next intermediate gold producer. In less than two years, the management team acquired a great project in TZ, released an updated Feasibility Study in February 2022, and completed a $481 million comprehensive financing package in a turbulent and volatile capital markets environment. This construction decision is an important milestone which has been achieved by de-risking the technical, permitting and funding aspects, and that confirm the TZ project is both a robust and responsible development opportunity. We are happy to see step one of our "Buy, Build, Operate" strategy progressing as planned, and are excited to commence full construction of TZ, for what will be one of the largest primary gold mines in Brazil."

"The updated feasibility study from February 2022 incorporated many of inflationary pressures seen in the industry, while still demonstrating very positive results of NPV5% of $622 million and IRR of 24% using a $1,600 per ounce gold price. We are very pleased that the regulators are in agreement with the high quality of our ongoing detail engineering work and have approved several of the key permit extensions we had requested. Lastly, we welcome additional highly qualified team members with extensive relevant experience to continue to advance TZ. With this formal construction decision, we target commercial production at TZ in the second half of 2024."

Louis Gignac Sr., Chairman of the Board of Directors of GMIN, commented: "The Board of Directors' formal decision to begin construction on TZ reflects our confidence in the significant value that the Project can bring to stakeholders in the State of Pará and all GMIN shareholders. The Board also extends its gratitude to GMIN's established supportive shareholders as well as the new shareholders established through its recently completed financing package, with whom we are fully aligned to grow GMIN into the next intermediate gold producer, using TZ as the foundational asset."

ESG and Permitting Update

The Corporation and its Brazilian subsidiary, Brazauro Recursos Minerais S.A. ("Brazauro"), maintain active and constant contact with all relevant environmental and governmental authorities, including the State Secretariat of Environment and Sustainability ("SEMAS"), Instituto Chico Mendes and Biodiversity ("ICMBio"), Equatorial Energia ("Equatorial"), National Agency of Electric Energy ("ANEEL"), National Mining Agency ("ANM"), and the Institute of Colonization and Agrarian Reform ("INCRA").

Environmental Permitting

GMIN has received all the necessary environmental installation permits to progress with full construction, which include:

  • Site installation license valid until August 2024
  • Forest Suppression Authorization and related fauna and flora permits for the site
  • Tubular well drilling and use permit for the temporary camp and construction
  • Grant for release of sanitary sewage from the site
  • Tubular well permit for permanent camp and aggregate plant
  • Licenses for the transmission line, landfill, concrete plant, fuel station and tailings dam are currently valid and being further extended by SEMAS

Site preparation activities at TZ started on August 15th and focused initially on the permanent camp area where full construction is scheduled to commence in September. Our construction activities are supported by Brazauro's environmental team which follows thorough protocols to rescue fauna and flora limiting any potential impact to the local environment and ensuring a stable ecosystem.

Health & Safety

The health and safety of employees, contractors and other stakeholders is at the forefront of the Corporation's values and objectives. A total of 250,580 hours has been worked year to date without any Lost Time Incidents.

Human Resources

Brazauro has grown to a workforce of 252 employees and contractors. Brazilian employees represent 98% of our workforce, of which 70% are from local communities and the State of Pará.

Additional recruitment job fair days were held in our neighboring communities where we collected almost 200 resumes and conducted over 100 interviews. We now have over 1,000 resumes in the database in our effort to hire locally.

Employee Training

The construction working training programs in collaboration with the National Industrial Training Service ("SENAI") has graduated 24 successful students from its first training camp. The Program's main goal is to contribute to the socio-economic development of the micro-region of Itaituba and the southwestern region of the State of Pará by promoting employment, providing training and possibility to participate in the implementation phase of the TZ Project. The second class started in August 2022.

Social programs for the development of the region proposed in the environmental licenses are being implemented, such as environmental education, training of local labor and support to the development of economic diversification. Other social programs are under development to add even more local value with income generation, education, and other development opportunities.
