Paranaíta Gold Project Update
Consistent 700m vein with visible gold mineralisation
Jangada Mines Plc (AIM: JAN), a Brazil focussed natural resource development company, is pleased to announce a positive update on its fully funded exploration programme at the 7,211-hectare Paranaíta Gold Project ("Paranaíta" or the "Project") located in Brazil's historically significant Alta Floresta-Juruena Gold Province.
The programme aims to expand the current resource from 210,000 to ~350,000 oz Au under the JORC code, and fast-track a PEA for a high-grade, open pit mine producing ~20,000 oz Au/year. The priority is the high-grade TP2 - c.106,600 oz @ 16.65 g/t Au and TP3.2 (within TP3) - c.34,600 oz @ 1.35 g/t Au zones, two of the six identified targets along the 8km mineralised corridor which has 15+ high-grade gold occurrences and historical sampling up to 135 g/t Au.
The following progress has been made at Paranaíta since exploration began in September 2025:
Trenching:
· 21 of the planned 31 100m trenches have been excavated with the remaining expected to be completed by third week of October. (See Figure 1)
· Visual interpretation from the trenches TR-02 to TR-07 identified a consistent 700m vein with clearly defined mineralisation. (See Figure 2)
· The 31-trench programme, extending to 3,100m in total, will guide the planned drilling campaign locations.
Sampling & Analysis:
· 68 samples sent for chemical analysis on 2nd October to SGS Geosol with grade results anticipated to be ready in 30 days.
· Visible sulphides are present in multiple samples.
· 14 grab samples collected from TP3.2 area, a high-grade shallow target zone, which will be sent to the lab with additional samples from the remaining trenches as part of the QAQC verification programme.
Topographic Surveys:
· Two topographic surveys have been executed. These have mapped the trenches and sampling at the TP2 target and will be used in the upcoming resource modelling.
Drilling Contract:
· A contract to conduct 1,800m of diamond drilling ('DD') has been signed with Sondagem Asafe, with two rigs expected to be on-site by end of October.
· The 15-hole programme is expected to last 10 weeks, with updates released as appropriate during the drilling campaign.
Jangada CEO, Paulo Misk, said: "Exploration at the high grade Paranaíta Gold Project is progressing well. The identification of 700m of continuing vein mineralisation is an excellent start and underpins the prospectivity of the targets. Samples with visible gold have been sent for analysis and we look forward to the return of the assays from an area that already has c.106,600 oz @ 16.65 g/t Au. This TP2 high grade shallow zone will be the focus of the drilling campaign, and I am delighted to confirm that we have now signed a contract for the 15 hole 1,800m DD campaign.
"We are building a Brazil-focused gold producer, and the development programme underway is exciting. Matto Grosso and the Alta Floresta-Juruena Gold Province offer significant opportunity, and I look forward to results of the current work as we aim to rapidly scale Jangada and create long-term value for all stakeholders."

PARANAITA PROJECT & EXPLORATION PROGRAMME DETAILS:
Jangada exploration programme at Paranaíta, is focussed on validating the existing gold resource of approximately 210,000 ounces ('oz') gold ('Au'), currently classified under the Brazilian Comissão Brasileira de Recursos e Reservas (CBRR) standards, and expand it to around 350,000 oz Au, under JORC standards. The Company's objective is to deliver a Preliminary Economic Assessment ('PEA'), targeting a high-grade, open-pit gold operation producing 20,000 ounces of gold per year.

Paranaíta sits on an 8 km east-west mineralised corridor hosting at least 15 high-grade gold occurrences. Current resources total approximately 210,000 oz Au at 3.165 g/t, with TP02 and TP3.2 among six priority zones for near-term open-pit development. TP2 contains 199,090 tonnes at 16.65 g/t Au for 106,600 oz Au, while TP3.2 contains 794,650 tonnes at 1.35 g/t Au for 34,588 oz Au, providing a strong platform for growth.
Following the recent site visit, Jangada's technical team has reviewed a substantial body of historic exploration data, valued at approximately US$2 million, allowing refinement of the new fully funded exploration programme.

The exploration licences are in good standing and will be upgraded to development and production status upon completion of the PEA. The region already hosts a number of producing operations, and the Board sees no impediment to the advancement of the Project.
The exploration programme is based on significant historical data, which has underscored the strong prospectivity of Paranaíta. Sampling returned robust results, with mineralisation hosted both in quartz veins and as disseminated gold within altered biotite granite. Of 66 samples tested, 31 assayed above 1.0 g/t Au and 16 above 10.0 g/t Au, with the highest returning 135 g/t Au.
Drilling results from previous programmes also highlight the Project's potential. At the East Traira target, hole ETR_DDH01 intersected 5.0 metres at 5.48 g/t Au, including 1.0 metre at 18.81 g/t Au and 3.0 metres at 8.77 g/t Au. Historical trenching has returned equally encouraging results, including 3.8 metres at 12.5 g/t Au and 2.1 metres at 19.3 g/t Au. Paranaíta is considered to be open-pittable, with six high-priority zones already identified, and is underlain by a porphyry-epithermal magmatic-hydrothermal system, offering significant geological upside.
