Paranaíta Gold Project Update

Highlights

· Trenching returns gold grades of up to 4.3g/t and confirms 800m strike length;

· 1,100m of drilling completed;

· First assay results from drill programme returned grades of up to 3.1g/t over 16.2m;

· Remainder of drilling assay results expected in February 2026;

· Exploration results reaffirm Company view of Paranaíta's ability to materially expand on existing open-pitable JORC Resource of 210,000 oz Au @3.165 g/t.

Jangada Mines Plc (AIM: JAN), a Brazil focused natural resource development company, is pleased to announce an update on exploration work being conducted at the 7,211-hectare Paranaíta Gold Project ("Paranaíta" or the "Project") located in Brazil's historically significant Alta Floresta-Juruena Gold Province.

Exploration activities, some of which are ongoing, include sampling, drilling and geophysical surveys, with the objective being to define a shallow open-pit mining opportunity at the Project. Preliminary results are meeting expectations and confirming the Project's potential, with several additional promising targets having been identified for future exploration.

Trenching & Soil Sampling:

The trenching programme, while primarily focused on identifying geological structures, returned encouraging gold grades from soil samples. When combined with previous results and historical artisanal mining data, the trenching programme confirmed a NE-SW trending mineralised structure extending over more than 800m in strike length and up to 100m in depth at the TP-02 target.

Trenching results include grades of up to 3.1 g/t Au, as well as continuous intervals of up to 20m in the TR-JG-04 trench area. Additional positive results were obtained in trenches TR-JG-05A and TR-JG-05B areas, with grades reaching up to 4.3 g/t Au.

At TP-3.2, soil sampling delivered strong results, including grades up to 6.4 g/t and continuous intervals of up to 32m above the cut-off grade in the trench TR-JG-25B area. Additional anomalous results were recorded in the TR-JG-28 and TR-JG-22 trench areas.

Drilling:

The drill programme is focused on expanding the current resource from 210,000 oz Au @3.165 g/t to ~350,000 oz Au under the JORC code. The TP2 and TP3.2 zones have a resource of c.106,600 oz @ 16.65 g/t Au and c.34,600 oz @ 1.35 g/t Au respectively and are two of the six identified high priority targets along the 8km mineralised corridor. This corridor has 15+ high-grade gold occurrences and historical sampling up to 135 g/t Au.

A total of 1,100 m of drilling has been completed to date, and the programme is currently paused pending receipt of all results. Core samples from the first drill hole #2 at TP-02 confirmed the encouraging results from trenching and sampling, intersecting multiple mineralised intervals with grades up to 3.1 g/t and a total mineralised length of 16.2m. These are consistent with the geological prognosis of GE21, the primary vendors of the Project.

Assay results from the remaining holes from the drilling programme are expected this month. Once received and in tandem with GE21, detailed geological modelling will take place to ascertain the next step of resource delineation, following which the remainder drill holes of the programme will be planned with the aim of strategically expanding the current mineral resources. 

Jangada CEO, Paulo Misk, said: "Supported by the current favourable gold market conditions, initial results from Paranaíta reinforce our confidence in achieving the objective of defining a shallow open-pit mining opportunity at the Paranaíta Project. The trench results, which allowed the demarcation of the 800m mineralised structure and its confirmation in the drill holes executed so far, are encouraging, supporting our learned opinion that the TP02 target of the Paranaíta Project is scalable. Once the drilling results are received, we will work closely with GE21 to both plan additional drilling and deliver an enhanced geological model, with the aim of expanding the initial inferred mineral resource of 210,000 oz Au (currently reported under the Brazilian Comissão Brasileira de Recursos e Reservas standards) and classifying it to JORC standards."
