Reports Q2-2026 Production & Operational Highlights

Reports Q2-2026 Production & Operational Highlights Serabi Gold plc (“Serabi” or the “Company”) (AIM: SRB, TSX: SBI, OTCQX: SRBIF), the Brazilian focused gold mining and development company, is pleased to announce the Company’s production results and operating highlights for Q2-2026 (all financial amounts are expressed in U.S. dollars unless otherwise indicated). Q2-2026 OPERATIONAL HIGHLIGHTS Quarterly gold production of 11,007 ounces, a 5% increase from Q2-2025. Cash as of 30 June 2026 of $65.7 million vs $64.4 million as of 31 March 2026.

Company remains debt free; having repaid $5.3 million to Banco Santander in Brazil during Q1-2026. Installation of the 4 th  ball mill at Palito Complex progressing on time and budget, expected to be operational by Q4-2026 and will increase annual processing throughput to 330ktpa in 2027. The full transition from selective open stoping to mechanised sublevel stoping at Coringa remains on track for Q4-2026.

Coringa Mine currently operates under a 3-year GUIA licence which expires on January 29, 2027. Discussions are ongoing with the Agência Nacional de Mineração (“ANM”), regarding the possible extension of the current GUIA. For the full mining licence (“LI”) at Coringa, the Company requires a change of land use approval from the Instituto Nacional de Colonização e Reforma Agrária (“INCRA”) as well as the approval of the Estudo de Componente Indígena (“ECI”) from FUNAI, which are both progressing well.

Successful site visit by the local Indigenous communities to Coringa occurred on July 17, 2026. Change of land use is in the final stage, requiring approvals by INCRA at the state and federal levels. Based on the assumption that the LI will be awarded by Q4-2026, the Company remains on track to deliver FY2026 consolidated production in excess of a record 53,000 ounces gold.

Mike Hodgson, CEO of Serabi, commented: “Serabi delivered a solid second quarter with over 11,000 ounces of gold produced, taking our first half total gold production to over 23,000 ounces. This performance was broadly in line with budget with quarterly production expected to increase in the second half of the year. Despite lower realised gold prices in Q2, development of the Galena and Serra South zone at Coringa and approximately $4 million of one-time G&A and tax charges, Serabi ended the quarter with an increased cash balance of $66 million following record cash generation in Q1 while maintaining a debt-free balance sheet.    Operationally, Coringa continued to perform strongly, with milled grades of 7.41g/t gold.

The move to mechanized sublevel open stoping method has continued, which the Company anticipates will be complete by year end bringing benefits to cost, output and safety. Development of the third zone at Coringa, Galena, is advancing well. A fourth zone at Coringa, Serra South, which was a significant discovery from the 2025 brownfield exploration programme, had development initiated during the quarter.

At Palito Complex, production was impacted by milled grades averaging 5.26 g/t Au YTD, compared to over 6 g/t Au in FY2025. Activity continued across several established zones, with development focused on G3. Stoping is expected to recommence at G3 in the second half, which should support improved grades and production.

We continue to make steady progress on the LI at Coringa. The LI is issued by SEMAS, the state environmental agency, who in turn are awaiting two approvals;   the ‘change of land use’ from the land registry body, INCRA which has been technically approved at both state and federal levels and now awaits final legal sign off. The second approval required by SEMAS is from FUNAI, the Indigenous government agency, who need to protocol the approval of the Estudo de Componente Indígena (ECI or Indigenous Impact Study).    Since the ECI was physically presented and positively received by the Indigenous communities in March 2026, numerous consultations have taken place including a successful second site visit by the local Indigenous communities to Coringa Mine on 17 July 2026.

During the quarter the Company released updated reserve estimates and resource estimates for the Palito Complex and Coringa Mine, based on the approximately 38,000 metres drilled in 2025. In only our first year of Phase 2, our consolidated M&I resource increased to 731koz Au and our consolidated inferred resource to 653koz Au, which is more than half-way towards our growth target. Looking ahead, Serabi remains in a strong cash position with zero debt and multiple organic growth catalysts expected later this year.

This includes the Palito Complex plant expansion which remains on track and on budget for completion by Q4-2026 and the transition to mechanized sublevel open stoping method at Coringa targeted for year end. We expect our production profile will increase sequentially through the remainder of the year and anticipate another record year of production in 2026, with production guidance in excess of 53,000 ounces.” OPERATIONAL RESULTS            (1)   The table may not sum due to rounding.            (2)   Production numbers are subject to change pending final assay analysis from refineries. Group production for the second quarter was 11,007 ounces.

Group ore mined during the quarter was 59,094 tonnes at 6.19 g/t Au compared to 54,965 tonnes at 7.06 g/t Au for the first quarter of 2026. The Palito Complex process plant treated 57,122 tonnes at 6.21 g/t Au compared to 54,587 tonnes at 7.05 g/t Au for Q1-2026. A total of 3,903 metres of horizontal development has been completed for the quarter of which 2,151 metres was ore development.

The balance was the ramp, crosscuts and stope preparation development. The Coringa Mine continues to perform well. On the Serra zone, production was focused on the levels of 260m, 190m, 158m, 143m, 125m, and 106m, with development on levels 170m, 158m, 126m, 104m and 88m.

On the Meio zone, development is focused on level 271m and stoping ongoing on levels 336m and 286m. The new Galena zone is in development with the main ramp currently at the 249m level and sill drive development on levels 285m and 269m. Coringa Mine operates under the terms of the 3-year GUIA licence which permits the transportation of 100,000 tonnes of ore per year as previously reported.

Palito Complex production and development is varied, with production from the Barrichello, G3, and Piquet zones. Development is ongoing on the Senna and G3 veins, ranging from levels -15m down to -210m level on G3.    FINANCE UPDATE Cash balance at the end of June 2026 was $65.7 million. During Q1-2026, the Company fully repaid its $5.3 million unsecured loan arrangement with Banco Santander and is now debt free.

Serabi closely monitors the performance of its own facility against results from independent laboratory analysis for quality control purpose.

As a matter of normal practice, the Company sends duplicate samples derived from a variety of the Company's activities to accredited laboratory facilities for independent verification. Since mid-2019, over 10,000 exploration drill core samples have been assayed at both the Palito laboratory and certified external laboratory, in most cases the ALS laboratory in Belo Horizonte, Brazil. When comparing significant assays with grades exceeding 1 g/t gold, comparison between Palito versus external results record an average over-estimation by the Palito laboratory of 6.7% over this period.

Based on the results of this work, the Company's management are satisfied that the Company's own facility shows sufficiently good correlation with independent laboratory facilities for exploration drill samples. The Company would expect that in the preparation of any future independent Reserve/Resource statement undertaken in compliance with a recognized standard, the independent authors of such a statement would not use Palito assay results without sufficient duplicates from an appropriately certificated laboratory.
