Bravo Mining Corp. reported assay results from the Babylon target area, located adjacent to the North Sector of its 100%-owned Luanga palladium + platinum + rhodium + gold + nickel deposit, located in the Carajás Mineral Province, Pará State, Brazil. Follow up drilling to the magmatic Ni/Cu-rich mineralization in the Babylon region continues to show encouragement, with higher grades and mineralized thicknesses than reported in May 2026.
These results continue to suggest potential for additional mineralization below the existing Luanga PGM+Au+Ni Deposit. The preliminary interpretation from the recently completed Deep IP survey line that also covers Babylon appears to support the rational for deeper testing below the known mineralization defined to date as well as following up on the high grade PGM+Au mineralization also intersected in this drill hole. Approximately 7.6km (3 lines) of IP completed to date, out of a planned 50km IP survey program.
DDH26LU347 tested an anomaly generated from Bore Hole Electromagnetics (“BHEM”) on previously reported drill hole, DDH26LU330, successfully intercepting a massive to semi-massive sulphide zone from 205.58m downhole. The sulphide zone is associated with a chromitite interval hosted in orthopyroxenites of the Luanga Transition Zone, and consists of pyrrhotite (gangue), pentlandite (primary Ni sulphide mineral) and chalcopyrite (primary Cu sulphide mineral), as shown in polished thin section. DDH26LU347 also intersected a separate 6.0m interval grading 6.81 g/t PGM+Au from 122.70m downhole, with low sulphide values.
BHEM surveying is planned to assist in further follow-up drilling. The Deep Induced Polarization (“IP”) survey associated with ongoing Cu-Au exploration, which also covers the Babylon target, has identified a significant IP anomaly at depth, which warrants priority drill testing. Drilling Highlights: DDH26LU347 from 122.70m to 128.70m, 6.00m @ 0.02 g/t Au, 3.84 g/t Pt, 2.30 g/t Pd, 0.64 g/t Rh, 0.01% Ni, 0.01% Cu, 6.81 g/t PGM+Au (FR/LS); from 205.58m to 219.02m, 13.44m @ 0.02 g/t Au, 0.77 g/t Pt, 1.21 g/t Pd, 0.02 g/t Rh, 1.55% Ni, 0.33% Cu, 2.02 g/t PGM+Au (FR); including 205.58m to 212.30m, 6.72m @ 0.03 g/t Au, 1.34 g/t Pt, 1.73 g/t Pd, 0.04 g/t Rh, 2.25% Ni, 0.55% Cu, 3.14 g/t PGM+Au (FR).
All ‘From’, ‘To’ depths, and ‘Thicknesses’ are downhole. Intercepts are estimated at 102% of true thickness. Type: FR = Fresh Rock.

The most recent drill hole targeting Ni/Cu sulphides proximal to the Luanga Deposit, DDH26LU347, is in the North Sector, approximately 300m south of the Babylon target and stratigraphically below and immediately east of the main PGM+Au+Ni mineral resource. DDH26LU347 was designed to test an Electromagnetic (“EM”) plate generated from the BHEM survey conducted on nearby previous hole DDH26LU330 drilled in this area. EM data was processed and interpreted by Bravo’s geophysical consultants, delineating a high conductivity plate model, dipping 40 degrees at approximately a 270-dip direction.
DDH26LU347 successfully intercepted a massive to semi-massive sulphide zone starting at 205.58m downhole. The sulphide mineralization is associated with a chromitite interval hosted in an orthopyroxenite layer of Luanga’s Transition Zone, and consists of pyrrhotite (“Po”), pentlandite (“Pn”) and minor chalcopyrite (“Ccp”). Pentlandite is mainly present as fine- to medium-grained crystals, with minor exsolution lamellae in pyrrhotite.
The well-preserved mineral textures and close association of chromite with the sulphide mineralization, indicates that a sulphide liquid pool was segregated and concentrated at this portion of the Luanga Mafic-Ultramafic (“MUM”) intrusion. Euhedral chromite crystals with enclosed sulphide blebs and partially corroded faces indicate the coexistence of chromite and the immiscible Ni-PGE bearing sulphide liquid. This supports a magmatic origin to the mineralization, thus clearly related to the Luanga MUM intrusion.
To date, three lines of IP surveying have been completed as part of the ongoing Cu-Au exploration program. One of these survey lines covers the Babylon target, along an East-West 2km long traverse. The sections and preliminary interpretations of the IP data at Babylon highlight strong chargeability and a low-resistivity anomalies that appear to correspond to the Babylon sulphide mineralization, likely extending deeper and potentially at a higher angle than the current drilling.
Based on this encouraging outcome, the IP data will be integrated with the existing Babylon datasets (geology, drilling and EM) to drill test the deep target. A total of 442 drill holes has been completed by Bravo to date, for 96,887 metres, including 8 metallurgical holes (not subject to routine assaying). Results have been reported for 396 Bravo drill holes to date.
Assay results for 46 holes are currently pending (excluding the metallurgical holes), some of which relate to exploration drilling outside the Luanga PGM+Au+Ni resource area. In total, 58 trenches have been completed to date (for 10,901 metres), with results from 6 trenches currently pending.
