Project Development Highlights
| ● | Toroparu – Advancing Toward a Potential Early 2027 Construction Decision |
| ○ | The Toroparu PFS is targeted for completion in November 2026, including Aris Mining’s first mineral reserve estimate for Toroparu. |
| ○ | The PFS incorporates an execution strategy including experienced mining contractors, with costs supported by competitive international quotations, and a combination of engineering and construction contracting models as well as self-performed work, selecting the most appropriate delivery approach for each project area. This approach is designed to strengthen cost and schedule control while managing execution risk compared with the owner-mining strategy contemplated in the 2025 PEA. |
| ○ | Early works continue, including construction of the Puruni River bridge to strengthen equipment access and regional connectivity. |
| ○ | The Large-Scale Mining License application has been submitted, and Aris Mining is working collaboratively with the Government of Guyana to advance the permitting process. |
| ● | Soto Norte – Permitting Milestone Advancing |
| ○ | As detailed in a new release on September 30, 2026, recent government actions have improved regulatory clarity for Soto Norte's environmental licensing pathway. These include the revocation of the La Baja permanent reserve and the revocation of the August 2026 extension of the Temporary Reserve Area, restoring its original March 4, 2027 expiry date. In addition, on July 29, 2026, the National Mining Agency (ANM) approved the modification to the PTO for Soto Norte in respect of mining concession 0095-68, where the deposit is located. In approving the plan, the ANM reviewed Soto Norte’s geology, mineral resources and reserves, mine design and production plan. |
