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 2(nd) 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.
