Please try againEXPLORATION UPDATE HIGHLIGHTSThe Company is currently in the second year of its Phase II organic growth strategy to expand the total Group mineral inventory to +1.5Moz Au, with the programme expected to complete October 2026. 2025 brownfield exploration programme increased 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).During H1-2026 20,831 metres of diamond drilling were completed, comprising 11,522 metres across 37 holes at Palito and 9,309 metres across 42 holes at Coringa.The 2026 brownfield exploration programme totals 32,000 metres across Palito and Coringa, with six drill rigs currently operating across the two sites.Recent results from the 2026 brownfield exploration programme continue to support resource growth potential including: 26-SR-055 – 1.38 m @ 11.85 g/t Au, including 0.42 m @ 37.10 g/t Au (Coringa Serra South)26-SR-059 – 2.20 m @ 5.89 g/t Au, including 0.40 m @ 13.40 g/t Au, and 1.19 m @ 6.87 g/t Au, including 0.49 m @ 16.55 g/t Au (Coringa Serra South)26-ME-013 – 1.70 m @ 16.13 g/t Au, including 0.45 m @ 35.59 g/t Au (Coringa Meio)26-SR-062 – 1.00 m @ 6.85 g/t Au, including 0.25 m @ 25.80 g/t Au (Coringa Serra)26-FC-005 – 1.00m @ 10.11 g/t Au, including 0.25m @ 40.30 g/t Au (Coringa Cabaça)26-ME-006 – 1.50m @ 4.01 g/t Au (Coringa Encosta)26-MS-001 – 1.12m @ 6.12 g/t Au, including 0.43m @ 15.20 g/t Au (Palito Massa)Results obtained to date have supported a number of new prospective models and reinterpretations. The exploration team is concentrating efforts on specific priority trends while ensuring continuous coverage of the main zones, enabling a more proactive stance while optimizing resource allocation, reduction of rework, and improving overall operations efficiency.Reinterpretation of the G1-G3 corridor at Palito identified new structural drill targets with drilling to follow in H2-2026.Updated Mineral Resource Estimates expected in Q1-2027 incorporating all validated results from the 2026 brownfield exploration programme.Mike Hodgson, CEO of Serabi, 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 Q1-2027, incorporating the drill results since our last update.This advertisement has not loaded yet.This advertisement has not loaded yet, but your article continues below.We look forward to continuing to unlock exploration value across our portfolio, where the 2025 brownfield exploration programme alone contributed to a significant increase in our total mineral inventory. We will continue to leverage our proven exploration, permitting expertise, along with our well established in-country relationships to execute on our strategy of creating a premier gold growth company in Brazil.”DETAILED RESULTS AND TECHNICAL DISCUSSION2026 Brownfield Exploration Program at Coringa Mine UpdateFigure 1 – Map of Select Targets and Intercepts at Coringa MineThe 2026 brownfield exploration programme at Coringa has drilled 9,309 metres to date in 42 diamond drill holes primarily focused on drilling identified targets along trend to the northwest and southeast of the currently producing Serra and Meio zones.Year-to-date results continue to demonstrate the significant growth potential of the district, with positive results generated from multiple target areas including Serra South, Serra, Meio and satellite targets such as Cabaça and Encosta. Recent drill results continue to confirm the geological controls responsible for the Serra and Meio deposits extend beyond the currently defined resource areas.The discovery of the Serra South zone in 2025, located approximately 500 metres southeast of the currently producing Serra zone, represents significant validation of the Company’s exploration model and demonstrates the potential for additional mineralized centres to occur along the broader, district-scale, structural corridor. Recent results include 1.38 m @ 11.85 g/t Au, including 0.42 m @ 37.10 g/t Au, in hole 26-SR-055 and 2.20 m @ 5.89 g/t Au, including 0.40 m @ 13.40 g/t Au, and a second interval of 1.19 m @ 6.87 g/t Au, including 0.49 m @ 16.55 g/t Au, in hole 26-SR-059, confirming continuity of the mineralised system along strike and at depth. Ramp development of Serra South zone commenced in Q2-2026.Drill results from the Meio zone continue to demonstrate potential for resource growth immediately southeast and along trend of the current mining area. Hole 26-ME-013 returned 1.70 m @ 16.13 g/t Au, including 0.45 m @ 35.59 g/t Au. Together with additional positive intersections from holes 26-ME-012, 26-ME-009, 26-ME-010 and 26-ME-007, these results define a mineralized corridor extending for more than 200 metres beyond the limits of the current underground development and highlight the potential for future resource additions and mine-life extension at the Meio zone.At Cabaça, hole 26-FC-005 intersected 1.00 m @ 10.11 g/t Au, including 0.25 m @ 40.30 g/t Au, from approximately 42 metres downhole. The shallow, high-grade intercept confirms the presence of significant gold mineralisation 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 m @ 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 H2-2026 was designed to test the lateral and vertical continuity of the mineralised structure.At Sr. Domingos, multiple priority drill targets were generated from discrete induced-polarisation anomalies within a previously untested portion of the Coringa district. The programme represents the first systematic drill evaluation of the target and is designed to determine whether the geophysical responses are associated with sulphide-bearing structures similar to those hosting gold mineralisation elsewhere at Coringa. Initial drill testing commenced during July.At Pista, multiple drill targets have been defined along an approximately 400-metre gold-in-soil anomaly supported by historical artisanal workings, continuous quartz-vein structures and encouraging rock-chip results of up to 7.46 g/t Au. Mapping identified a brecciated quartz vein containing fresh pyrite, together with a broader vein and stockwork system developed along prospective northwest-southeast structural trends. The combination of geochemistry, mapping and surface mineralisation has allowed several priority drill sites to be defined.Recent highlight intercepts for Coringa’s 2026 brownfield exploration programme include:Hole_IDTargetObservationFromToInterval (m)Grade(Au g/t)Laboratory Results26-SR-053Serra South 76.3377.250.924.65ALS Resultincluding76.8777.250.3811.05ALS Resultand94.4595.511.064.40ALS Resultincluding94.9795.510.545.88ALS Result26-SR-055Serra South 197.63199.011.3811.85ALS Resultincluding197.93198.350.4237.10ALS Resultand202.12203.121.0014.65ALS Resultincluding202.37202.620.2557.20ALS Result26-SR-058Serra South 122.55123.500.954.48ALS Result26-SR-059Serra South 233.00235.202.205.89ALS Resultincluding234.80235.200.4013.40ALS Resultand280.81282.001.196.87ALS Resultincluding281.06281.550.4916.55ALS Resultand298.15299.301.152.92ALS Resultincluding299.00299.300.305.71ALS Result26-SR-062Serra 121.10122.101.004.67ALS Resultincluding121.40121.800.4011.65ALS Resultand354.62355.621.006.85ALS Resultincluding355.00355.250.2525.80ALS Result26-SR-063Serra 510.24511.241.003.12Palito Resultincluding510.74511.240.506.2Palito Result26-FC-005Cabaça 42.0043.001.0010.11ALS Resultincluding42.4542.700.2540.30ALS Result26-FC-007Cabaça 34.5034.750.253.78ALS Result26-ME-006Encosta 4.425.921.504.01ALS Result26-ME-007Meio 181.00181.350.354.51ALS Result26-ME-009Meio 96.4797.370.902.78ALS Resultincluding96.8097.120.327.56ALS Result26-ME-010Meio 171.70172.701.005.44ALS Resultincluding172.00172.250.2517.05ALS Result26-ME-012Meio 27.9528.951.003.44Palito Resultincluding28.2528.650.404.93Palito Result26-ME-013Meio 92.5594.251.7016.13Palito Resultincluding92.5593.000.4535.59Palito Result26-ME-014Meio 98.6299.721.102.25Palito Resultincluding98.8799.220.354.58Palito ResultNote: All drill results above have been sent to ALS for assay testing. ‘ALS Result’ denotes the results were assayed and test results received from ALS while ‘Palito result denotes assays drill results sent to ALS for testing but test results are not yet received and therefore represent Serabi internal assay results.Figure 2 – Location of Meio Infrastructure with Recent Exploration Drillholes2026 Brownfield Exploration Program at Palito Complex UpdateFigure 3 – Map of Select Targets and Intercepts at Palito ComplexThe 2026 brownfield exploration programme at Palito Complex has drilled 11,522 metres to date over 37 drill holes. The focus was to increase near-mine ounces, particularly at Senna, G3, Barrichello, Piauí and Massa.Drilling at Senna continues to confirm the continuity to the northwest and southeast of the mineralized structure, with hole 26-SE-020 returning 0.82m @ 3.99 g/t Au, including 0.25m @ 11.20 g/t Au and an additional intercept of 1.24m @ 3.62 g/t Au including 0.35m @ 5.53g/t Au and 0.35m @ 6.56g/t Au.The recently initiated drilling at Massa provided encouraging results, with hole 26-MS-001 returning 1.12m @ 6.12 g/t Au including 0.43m @ 15.20 g/t Au.At Piauí, hole 26-PI-019 intersected a broad mineralised interval of 9.93m @ 1.06 g/t gold, including two internal higher-grade intervals of 0.25m @ 6.26g/t Au and 0.25m @ 4.95 g/t Au. Together with additional mineralised intersections from surrounding holes, the result supports the interpretation of a broader mineralised envelope containing discrete higher-grade zones. Ongoing geological modelling is evaluating the geometry and continuity of the Piauí mineralised system.At Tatu, holes 26-TA-001 and 26-TA-003 returned narrow high-grade intersections of 0.28m @ 7.22 g/t Au and 0.25m @ 6.50 g/t Au, respectively. The results confirm the presence of high-grade gold-bearing structures at this early-stage target, although additional geological evaluation is required to establish their continuity and overall significance.Recent highlight intercepts for Palito’s 2026 brownfield exploration programme include:Hole_IDTargetObsFrom ToInterval (m)Gold Grade (Au g/t)Laboratory Results26-PI-019Piauí 79.0789.009.931.06ALS ResultIncluding 84.7585.000.256.26Including 85.0085.250.254.9526-PI-026Piauí 123.20123.600.403.20ALS Result26-TA-001Tatu 122.22122.500.287.22ALS Result26-TA-003Tatu 57.2557.500.256.50ALS Result26-SE-020Senna 48.2249.040.823.99ALS ResultIncluding 48.7949.040.2511.20 52.8153.831.023.49 238.95240.191.243.62Including 239.24239.590.355.53Including 239.6239.940.356.56 250.92251.360.443.7026-MS-001Massa 68.6168.860.255.95ALS Result 134.67134.930.265.78 144.05145.171.126.12Including 144.74145.170.4315.2026-GT-009G3 371.02371.380.364.75ALS Result26-GT-010G3 431.09432.101.017.41Palito ResultIncluding 431.09431.450.3613.11 483.61485.001.396.13Including 483.96484.210.2523.55Note: All drill results above have been sent to ALS for assay testing. ‘ALS Result’ denotes the results were assayed and test results received from ALS while ‘Palito result denotes assays drill results sent to ALS for testing but test results are not yet received and therefore represent Serabi internal assay results.Reinterpretation of G1-G3 Corridor to be Tested in H2-2026Through the integration of historical drilling, underground mapping and revised structural modelling, the exploration team developed a new geological framework suggesting several mineralized structures previously considered isolated potentially form a larger and more continuous mineralized system. The revised geological model incorporates structural offsets, branching vein systems and previously unrecognized dilation zones that may positively impact future exploration targeting and resource estimation. A diamond drilling programme was designed for H2-2026 to test priority targets generated from the updated interpretation.Figure 5 – Reinterpreted G1-G3 CorridorAbout Serabi Gold plcSerabi Gold plc is a gold exploration, development and production company focused on the prolific Tapajós region in Pará State, northern Brazil. The Company has consistently produced 30,000 to 40,000 ounces per year with the Palito Complex and is planning to double production in the coming years with the ramp up of the Coringa Mine. Serabi Gold plc recently made a copper-gold porphyry discovery on its extensive exploration licence. The Company is headquartered in the United Kingdom with a secondary office in Toronto, Ontario, Canada.The information contained within this announcement is deemed by the Company to constitute inside information as stipulated under the Market Abuse Regulations (EU) No. 596/2014 as it forms part of UK Domestic Law by virtue of the European Union (Withdrawal) Act 2018.The person who arranged for the release of this announcement on behalf of the Company was Andrew Khov, Vice President, Head of Investor Relations & Business Development.SERABI GOLD plcMichael Hodgson t +44 (0)20 7246 6830Chief Executive Officer m +44 (0)7799 473621Andrew Khov m +1 647 885 4874Vice President, Head of Investor Relations & Business Development e contact@serabigold.comBEAUMONT CORNISH LimitedNominated Adviser & Financial AdviserRoland Cornish / Michael Cornish t +44 (0)20 7628 3396PEEL HUNT LLPJoint UK BrokerRoss Allister / Georgia Langoulant t +44 (0)20 7418 9000TAMESIS PARTNERS LLPJoint UK BrokerCharlie Bendon/ Richard Greenfield t +44 (0)20 3882 2868CAMARCOFinancial PR – EuropeGeorgia Edmonds / Fergus Young t +44 (0)20 3757 4980Assay ResultsAssay 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.Forward-looking statementsCertain statements in this announcement are, or may be deemed to be, forward looking statements.
