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.

o Company remains debt free; having repaid $5.3 million to Banco Santander in Brazil during Q1-

2026.

• Installation of the 4th 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.

o Discussions are ongoing with the Agência Nacional de Mineração (“ANM”), regarding the possible

extension of the current GUIA.

• For the full mining licenc e (“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.

o Successful site visit by the local Indigenous communities to Coringa occurred on July 17, 2026.

o 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 .”

Assay Results

Assay results reported within this release include those provided by the Company's own

on-site laboratory facilities at Palito and have not yet been independently verified. 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.
