Construction

The following major milestones have been reached in construction:

• Improvements of deteriorated sections of the Transgarimpeira State Road from Morais Almeida to Jardim do Ouro were initiated;
• The municipal access road from Jardim do Ouro to site under the responsibility of Brazauro was upgraded with the installation of several culverts to improve overall drainage and to help control erosion during the rainy season. All wooden bridge approaches were installed and have enhanced safety on the road;
• The internal site road to the industrial area was completed;
• Four dorms of the 1,200-person permanent camp are completed and occupied, with work on track for completion of the full camp including welcome center, sewage treatment plant and water treatment plant in March;
• Permanent kitchen footings and walls were poured. The structural erection of the kitchen is advancing well with Civil, Structure and Architecture progress of 55% and overall completion reaching 50%; and
• Bulk fuel storage of 420,000 liters is in process with civil works completed and tanks installed.

Pre-Production Mining

Pre-production mining in the starter pit was initiated with commissioning of the first mine fleet units with 590,000 tonnes of waste material excavated. The waste material was used for road construction and in the future will be used to construct the tailings dam. This material has undergone rigorous geotechnical testing to assure its suitability. The starter pit has recently reached fresh rock as expected, which provides competent material for construction purposes, as a source for aggregate, and filter material for constructing the FTSF. During the pre-production period the ore stockpile will reach approximately 2.4 million tonnes prior to commissioning representing about 6 months of mill feed.

Since the November 2022 issuance of the Declaration of Public Utility ("DUP") on the 138 kV power transmission line from Novo Progresso to TZ, by The National Agency of Electric Energy ("ANEEL"), powerline construction has commenced.

In summary:

• Detailed engineering of the powerline and substations was completed, submitted, and approved by Equatorial Pará Distribuidora de Energia S.A., the entity responsible for energy distribution in the state of Pará;
• Selection of contractors for forest suppression and powerline installation was finalized and all materials purchased;
