TZ: The drilling programs continued to test exploration targets within 5km radius around the existing infrastructure of the TZ gold mine, including testing the extension of the TZ deposit at depth and along strike. A total of 3,285 m of diamond drilling and 1,893 m of reverse circulation drilling were executed during this quarter. Within the TZ pit, 1,715 m were drilled to explore extension of the deposit at depth. For regional exploration, the focus was to test the main structural trend within 5 km to the infrastructure. Some of the results from drillholes returned 27.0 m at 0.85 g/t Au and 23.0 m at 0.91 g/t Au (BRZ-25-089A) south of the TZ pit, demonstrating the presence of gold, however continuity and volume were not reached. Building on insights gained from the southern exploration results, the team redirected its efforts to the northwest of TZ pit, where the geological trend shows strong potential and 1,016 m of diamond drilling were completed at Toca‑Toca during the last quarter.
             
Oko West: The main exploration focus was to test the NW Extension target. This target was generated from geological mapping, geophysics completed in 2025, gold anomalies in soil sampling, anomalous gold samples in trenches with multiple gold intercepts including 10.0 m at 0.72 g/t Au and 12.0 m at 0.29 g/t Au (OKWT24-105), highlighting approximatively +50m of anomalous gold grade. A total of 2,507 m of diamond drilling, 4,944 m of reverse circulation drilling, and 52 m of trenching were executed during this quarter in the NW Extension target.
             
Gurupi: Exploration drilling activities restarted at Gurupi in the fourth quarter, with two diamond drill rigs and one reverse circulation drill rig. Field activities continued to test the continuity of the Chega Tudo deposit to the north within the Maranhão State. Trenching and soil sampling were also collected. Exploration focused on Grodiacol targets with a total of 1,085 m of diamond drilling and 1,046 m of reverse circulation drilled since November 2025 following trench intercepts of 7.0 m at 2.76 g/t Au (GSUBT-25-005), 19.0 m at 0.96 g/t Au (GJIBT-25-001) and 13.4 m at 1.02 g/t Au (GUD-26-007). At a regional scale, 571 additional soil samples were collected, with most assays still pending.
