Jangada Mines plc (AIM: JAN), a Brazil-focused natural resources company, has announced the completion and interpretation of a geophysical survey programme at its Molly Gold Project in the Tapajós Province of northern Brazil. The programme identified 15 geophysical targets in total, nine of which have been ranked as high priority, across a 6,656-hectare licence area. The results demonstrate a strong correlation between newly identified structures and known gold mineralisation, reinforcing the company's geological model and providing a framework for the ongoing diamond drilling programme.

Key Points

  • Jangada Mines plc (AIM: JAN) is an AIM-listed Brazil-focused natural resources company
  • A 368.2 line-km MagDrone survey and 11.8 line-km ground IP survey have been completed at the Molly Gold Project in the Tapajós Province
  • 15 geophysical targets identified, nine ranked as priority, across areas including South Boomerang, Vivi, Esmeril, Eastpot and new area West Boomerang
  • Investors should watch for assay results from the ongoing 11-hole, approximately 1,400-metre diamond drilling programme, with three holes completed to date intersecting visible mineralisation

MagDrone and IP Surveys Map Extensive Structural Framework Across Molly Gold Project's 3,320-Hectare Survey Area

The geophysics programme comprised two distinct surveys conducted between 1 July and 7 November 2026. The MagDrone survey covered 3,320 hectares across the southern and western project area, flying 97 north-south lines at 100-metre spacing to map faults, shear zones and alteration zones. A ground Induced Polarisation survey across 14 lines at Vivi and Molly 2 tested structures below surface to depths of approximately 100 to 120 metres. Together, the surveys mapped a network of E-W and NE-SW structures, a prominent ENE-WSW structural corridor along the southern project area, and magnetic sources extending to depth, with upper surfaces mostly between 50 and 200 metres below surface.

Nine Priority Targets Confirmed at South Boomerang, Vivi, Esmeril, Eastpot and Newly Identified West Boomerang

The nine priority targets span five distinct areas, each with supporting geological evidence. South Boomerang hosts four priority targets associated with historical artisanal workings, with one drill hole of 200 metres planned. The Vivi target — where surface grab samples previously returned up to 306.23 g/t Au — hosts one priority target now being tested by seven drill holes totalling 900 metres. Esmeril returned grab samples of up to 26.56 g/t Au from quartz veins. West Boomerang is a newly identified area on the north-western extension of the Boomerang trend, supported by historical artisanal workings, with mapping and sampling planned for 2027. The announcement notes that grab sample grades are selective and not representative of average vein grades.

Geophysics Validated Against Molly 1's JORC Inferred Resource of 130,000 oz Au at 2 g/t and Vivi Surface Sampling

A key element of the programme was testing geophysical results against areas of confirmed mineralisation before applying them to generate new targets. The drill-confirmed Molly 1 deposit, which carries a JORC (2012) Inferred Resource of 130,000 oz Au at 2 g/t, and the Molly 2 target both sit on the southern ENE-WSW structural corridor identified by the MagDrone survey. The Vivi vein swarm, comprising at least seven mineralised quartz veins over approximately one square kilometre, coincides with priority target five. This correlation between geophysical signatures and known mineralisation supports the company's approach to directing future drilling across the broader licence area.

Three Drill Holes Completed With Visible Mineralisation Intersected; Assay Results Awaited

An 11-hole diamond drilling programme totalling approximately 1,400 metres is currently under way, comprising seven holes at Vivi, three at Molly 2, and one at South Boomerang. The announcement states that three drill holes have been completed to date — V01A, V02A and V03A at Vivi — all intersecting visible mineralisation, with samples currently undergoing assay testing. Hole V03A was drilled beneath the exposed Vivi 1 vein, where surface grab samples returned 151.23 g/t Au and 112.45 g/t Au. Investors will be watching for laboratory assay results, which will be reported once received and validated by the company.
