Molly Gold Project Sampling Results
'Multiple bonanza grade samples returned across three target areas'
Jangada Mines plc (AIM: JAN), a Brazil-focused natural resources company, is pleased to announce exceptional high-grade gold results from a multi-target grab sampling programme at its Molly Gold Project in the Tapajós Province, northern Brazil. Sampling across the Vivi, Molly 2 and newly identified Jane and Esmeril targets has returned high gold grades, particularly at Vivi and Molly 2, highlighting the presence of extensive gold-bearing vein systems and widespread mineralisation across the project area.
HIGHLIGHTS
· Further bonanza-grade gold at Vivi: Samples returned 151.23 g/t, 112.45 g/t, 49.93 g/t and 39.74 g/t Au, following an initial peak result of 306.23 g/t Au, alongside 166.00 g/t Ag, 2.19% Pb and 1.12% Zn.
· Consistently high grades at Vivi: Three samples exceeded 100 g/t Au, four exceeded 40 g/t Au, 10 exceeded 10 g/t Au and 19 exceeded 1.0 g/t Au.
· Extensive vein system at Vivi: Mapping and sampling identified a dense cluster of at least seven mineralised veins across approximately 1 km².
· New high-grade zones at Molly 2: Additional mineralisation identified grading 370.41 g/t Au (148.00 g/t Ag) and 241.30 g/t Au (57.50 g/t Ag), highlighting multiple mineralised zones with varying orientations and dips.
· Further upside from new targets: Jane and Esmeril returned highly encouraging results with the top samples being 26.56 g/t Au and 15.16 g/t Au from Esmeril
· Polymetallic mineralisation: Gold occurs alongside silver, copper, lead and zinc within structurally controlled quartz vein swarms aligned with regional trends.
· Pending assays: Second sampling programme across Vivi, Molly 2, Boomerang South and Eastpot on-going.
Jangada Chief Executive, Paulo Misk, said: "The latest results from the Molly Gold Project have exceeded our expectations, delivering further bonanza-grade gold mineralisation and reinforcing the project's exceptional potential as a multi-target, polymetallic system. At Vivi, recent samples returned up to 151.23 g/t Au, following the previously reported 306.23 g/t Au, while Molly 2 delivered grades of 370.41 g/t Au and 241.30 g/t Au. The consistently high grades, alongside associated silver, copper, lead and zinc mineralisation, highlight the potential for an extensive, structurally controlled mineralised system.
"We have now identified seven highly prospective target areas: Molly 1, Molly 2, Vivi, Jane, Esmeril, Boomerang South and Eastpot. The identification of gold mineralisation at Jane and Esmeril extends the project's prospective footprint to the south, while at Boomerang, with its 5km strike length, we have barely scratched the surface. We believe significant exploration upside remains across the project.
"Exploration continues at pace, with geological mapping ongoing, interpretation of the completed drone magnetic and induced polarisation (IP) surveys nearing completion, and aeromagnetic results expected shortly. Our fully funded Phase 2 drilling campaign is also nearing completion. Importantly, Molly is displaying geological characteristics similar to producing gold mines in the region, further strengthening our confidence in its potential to host a significant and commercial gold system."
DETAILS
Grab Sample Programme & Results
The results of most of the grab sampling programme across the Vivi, Molly 2, Jane and Esmeril targets within the Molly Gold Project have now been received, returning exceptional gold grades, particularly from Vivi and Molly 2. Results from Jane and Esmeril have also confirmed the prospectivity of these newly identified targets, warranting further follow-up exploration.
Importantly, numerous high-grade samples were collected directly from mineralised veins, highlighting the abundance of gold-bearing structures and extensive vein swarms across the project area. The presence of significant additional metal credits, including silver, copper, lead and zinc, further supports the interpretation of a potentially extensive, structurally controlled polymetallic mineralising system. Together, these results reinforce the prospectivity of the Molly Gold Project, highlighting its potential for multiple mineralised zones and further discoveries within the highly prospective Tapajós Province of Brazil.
A second sampling programme is underway with further assay results pending from Vivi, Molly-2, Boomerang South, and Eastpot.
The Vivi Target
The programme at Vivi was expanded following the initial discovery of bonanza-grade gold mineralisation, returning 306.23 g/t Au, accompanied by 166.00 g/t Ag, 2.19% Pb and 1.12% Zn from mineralised vein material. This exceptional initial result prompted further geological mapping and additional grab sampling of the identified mineralised veins, which subsequently returned further high-grade gold results including 151.23 g/t Au, 112.45 g/t Au, 49.93 g/t Au and 39.74 g/t Au. Across the programme, three samples exceeded 100 g/t Au, four exceeded 40 g/t Au, 10 returned grades above 10 g/t Au and 19 samples exceeding 1.0 g/t Au. These results highlight the occurrence of exceptional gold mineralisation across multiple sampled occurrences.
Sampling and surface mapping at Vivi has now identified a cluster of mineralised veins over an area of approximately 1km2 with the extent of the individual veins and the cluster yet to be fully determined.
Importantly the assay results also confirm the polymetallic nature of the mineralisation, with elevated silver, lead, zinc and copper concentrations consistent with a polymetallic hydrothermal mineralising system. This geochemical association, together with the distribution of high-grade gold-bearing veins, provides encouraging evidence of a broader mineralised system and may offer valuable indicators for identifying additional mineralised structures.
One of the mineralised structures identified at Vivi was systematically sampled through a comprehensive channel-sampling programme. A total of 78 samples were collected with 54 assay results pending from six channels oriented perpendicular to the main structure. In addition to these channel samples, assay results are pending from an external laboratory for a further 26 grab samples collected at Vivi.
The Figure below shows the Vivi identified mineralised quartz veins in yellow and the gold grade obtained after external lab analysis.

Geological mapping also identified multiple mineralised quartz veins displaying variable orientations and thicknesses, broadly consistent with the regional structural trends and dip directions recognised elsewhere within the Tapajós Province. The presence of several mineralised structures, rather than a single isolated vein, supports the interpretation of a potentially extensive, structurally controlled swarm of gold-bearing quartz veins.
The combination of high-grade gold assays, polymetallic mineralisation and multiple identified vein structures highlight the exploration potential of Vivi and expands the prospective footprint of the Molly Project. While grab samples are selective and not necessarily representative of average grades or mineralisation continuity the results provide a strong basis for further geological mapping, systematic geochemical sampling and structural interpretation to assess vein continuity and define priority targets for future drilling.
The Molly 2 Target
Following the drilling results announced on 17 August 2026, the Company decided to reassess the Molly-2 Target area to look for evidence of additional mineralised bodies and determine their potential extent. New mineralisation was identified, returning exceptional grades from grab samples, including 370.41 g/t Au and 148.00 g/t Ag, 241.30 g/t Au and 57.50 g/t Ag. These grades confirm the presence of multiple mineralised zones within a single target, with varying orientations and dips, forming a large, mineralised vein system. These results, in combination with the pending geophysical interpretations are anticipated to generate additional drill targets.
The Figure below shows the Molly-2 identified mineralised quartz veins and the gold grade obtained after external lab analysis.

The Jane and Esmeril Targets
The newly discovered Jane and Esmeril targets lie west of Vivi and were identified through evidence of artisanal mining in the area. A gold-bearing vein system is clearly present, and samples were collected from the veins at Esmeril with the highest of 15.16 g/t Au and 26.56 g/t Au.
Structures were identified along the boundary of the Molly Project claim, with their strike extending into the project area. Geophysical and geological mapping interpretations suggest that possible extensions of these structures lie within the Jane and Esmeril targets.
The work completed to date at these targets has been preliminary, and further detailed investigation is under planning.
The Figure below shows the Jane and Esmeril identified mineralised quartz veins and the gold grade obtained after external lab analysis.
