Tocantinzinho Project Update

Detailed Engineering

Detailed engineering is 43% complete, allowing for project procurement to progress to 100%. Notable advancements to date include:

• Procurement for all major equipment for the process plant has been completed
• Permanent camp drawings issued for all disciplines and construction is well underway
• Process plant design review on the piping & instrumentation diagrams is complete
• Significant progress has been made on the transmission line execution strategy, with construction slated to start before year-end

Procurement and Delivery

Overall Project procurement has progressed to 73% completion. Commitments to date total $160 million (34% of total), with expenditures and schedule tracking in line with the Feasibility Study dated February 09, 2022 (filed under GMIN's profile on Sedar, entitled 'Feasibility Study - NI 43-101 Technical Report, Tocantinzinho Gold Project.').

Construction and Pre-Production Mining

Open pit mining has been initiated in our starter pit phase. Excavated waste material will be used for construction purposes, as a source for aggregate, and fill material for constructing the dam of our tailings facility. During the pre-production, it is planned to stockpile approximately 2.4 million tonnes of ore prior to commissioning (~6 months of ore mill feed).

Exploration camp expansion is complete, with the installation of 10 additional sleepers expanding the capacity to 370 beds. The construction effort is currently focused on the permanent camp in order to increase capacity to 1,200 sleepers by yearend.

The following milestones have been achieved in construction work:

• 83% of earthworks and 50% of foundations completed for installation of the permanent camp
• Mine waste dump access road was completed
• All four bridges were completed on the main access road, with the remaining upgrade work ongoing
