Serabi Gold Reports Positive Results from 2026 Brownfield Exploration Program

Serabi Gold plc, a Brazilian-focused gold mining and development company, has announced positive results from its 2026 brownfield exploration programme at the Palito Complex and Coringa Mine. The programme, which aims to expand the company’s known gold resources, has already completed 20,831 metres of diamond drilling, with 11,522 metres drilled at Palito and 9,309 metres at Coringa. The exploration team is targeting high probability near-mine mineralization, with the programme expected to conclude in October 2026.

The 2025 brownfield exploration programme significantly increased the company’s consolidated Measured and Indicated (M&I) resources to 730,800 ounces of contained gold (2,485,800 tonnes @ 9.1 g/t Au) and consolidated inferred resources to 653,300 ounces (2,506,700 tonnes @ 8.1 g/t Au). The 2026 programme, which totals 32,000 metres across both sites, is being carried out using six drill rigs.

Recent drilling results have shown promising signs of resource growth potential. At Coringa, the Serra South zone, located approximately 500 metres southeast of the currently producing Serra zone, has returned high-grade intersections. Hole 26-SR-055 intersected 1.38 metres @ 11.85 g/t Au, including 0.42 metres @ 37.10 g/t Au. Hole 26-SR-059 returned 2.20 metres @ 5.89 g/t Au, including 0.40 metres @ 13.40 g/t Au and 1.19 metres @ 6.87 g/t Au, including 0.49 metres @ 16.55 g/t Au. These results confirm the continuity of the mineralized system along strike and at depth.

At the Meio zone, hole 26-ME-013 returned 1.70 metres @ 16.13 g/t Au, including 0.45 metres @ 35.59 g/t Au. Additional positive intersections from holes 26-ME-012, 26-ME-009, 26-ME-010, and 26-ME-007 define a mineralized corridor extending for more than 200 metres beyond the limits of the current underground development, highlighting the potential for future resource additions and mine-life extension.

At Cabaça, hole 26-FC-005 intersected 1.00 metres @ 10.11 g/t Au, including 0.25 metres @ 40.30 g/t Au, from approximately 42 metres downhole. This result confirms the presence of significant gold mineralization at this satellite target and further demonstrates the potential for additional mineralised centres outside the primary Serra and Meio zones.

At Encosta, hole 26-ME-006 intersected 1.50 metres @ 4.01 g/t Au from approximately 4 metres downhole. The result provides initial confirmation of a target defined by coincident soil-geochemical and induced-polarisation anomalies and supports an open strike opportunity extending for more than 300 metres. Follow-up drilling in the second half of 2026 is planned to test the lateral and vertical continuity of the mineralized structure.

At Palito, the Senna, G3, Barrichello, Piauí, and Massa targets have shown encouraging results. Hole 26-SE-020 at Senna returned 0.82 metres @ 3.99 g/t Au, including 0.25 metres @ 11.20 g/t Au and an additional intercept of 1.24 metres @ 3.62 g/t Au, including 0.35 metres @ 5.53 g/t Au and 0.35 metres @ 6.56 g/t Au. At Massa, hole 26-MS-001 returned 1.12 metres @ 6.12 g/t Au, including 0.43 metres @ 15.20 g/t Au. At Piauí, hole 26-PI-019 intersected a broad mineralised interval of 9.93 metres @ 1.06 g/t gold, including two internal higher-grade intervals of 0.25 metres @ 6.26 g/t Au and 0.25 metres @ 4.95 g/t Au. These results support the interpretation of a broader mineralised envelope containing discrete higher-grade zones.

The exploration team is also reinterpreting the G1-G3 corridor at Palito, which has generated several new structural drill targets. A programme designed to test these targets is planned for the second half of 2026.

Serabi Gold’s CEO, Mike Hodgson, commented, “Phase II of our organic growth strategy continues to yield success with the drill bit in the second year of our brownfield exploration drilling programme at Palito and Coringa. Today’s published high-grade drill results demonstrate the potential to delineate a larger resource at both Palito and Coringa to support production growth. We expect to conclude the 2026 brownfield exploration programme in October 2026 with an updated mineral resource estimate for both Palito and Coringa targeted for Q
