Bravo Mining's Luanga Project Reveals New High-Grade Nickel-Copper Zone Alongside Expanding Exploration Scope

Drill results from the Babylon target confirm a distinct style of sulphide mineralisation rich in nickel and copper, broadening the investment case at Luanga beyond its platinum group metal deposit.

  • Drill hole DDH26LU330 intersected high-grade magmatic sulphide mineralisation approximately 300 metres south of the Babylon target, returning 5m at 1.28 g/t PGM+Au, 1.0% nickel and 0.37% copper, including 2.7m at 2.11 g/t PGM+Au, 1.75% nickel and 0.68% copper.
  • The newly identified mineralisation carries higher nickel and copper grades relative to the existing Luanga PGM resource, classifying it as a chemically distinct ore type.
  • Four drill holes at the Babylon target (DDH25LU292-295) returned nickel-copper-PGM grades across multiple sulphide-rich intervals, indicating broad spatial continuity.
  • Management noted that magmatic nickel-copper sulphides of this type may be amenable to treatment in the same flotation plant being considered for the Luanga PGM resource, with minor modifications.
  • A 50-kilometre induced polarisation (IP) geophysical survey has commenced as part of a separately funded copper-gold exploration programme, further expanding the project pipeline.

Bravo Mining Corp. (TSX-V: BRVO, OTCQX: BRVMF) is a Canadian and Brazil-based mineral exploration and development company advancing the Luanga Project in the Carajas Mineral Province of Para State, Brazil. The company holds a 100%-owned PGM, gold and nickel deposit and is also exploring for copper-gold and magmatic nickel-copper mineralisation within the same project area. The Luanga Project benefits from road and rail access, proximity to an experienced local workforce, and connection to hydroelectric grid power. Bravo's exploration team includes local and international geologists with prior project experience in the Carajas region.

High-Grade Magmatic Sulphide Ni/Cu-PGM Mineralisation at the Babylon Target

Drill hole DDH26LU330, targeting nickel-copper sulphides near the Luanga deposit, intersected a roughly 22-metre thick sulphide zone approximately 300 metres south of the Babylon target and stratigraphically below the main PGM resource. Within that zone, two distinct intervals of semi-massive to massive sulphides were identified, with the best result returning 2.7 metres at 2.11 g/t combined PGM and gold, 1.75% nickel and 0.68% copper. The sulphide zone was found in the footwall, the rock layer sitting directly beneath the main Luanga deposit, hosted predominantly in harzburgite, a type of ultramafic rock.

Earlier drilling at Babylon itself (holes DDH25LU292 through DDH25LU295, drilled on the same cross-section) also returned sulphide mineralisation across cumulative thicknesses of up to approximately 35 metres in a single hole, including 4.88 metres at 1.59 g/t PGM+Au and 1.07% nickel in DDH25LU292, and 3.6 metres at 1.71 g/t PGM+Au, 1.33% nickel and 0.47% copper in DDH25LU293.

Chairman and CEO Luis Azevedo commented:

"The magmatic Ni/Cu-rich mineralization intercepted 300m south of the Babylon target, coupled with previous and ongoing work in and around Babylon, continues to strengthen the evidence for the potential of high-grade Ni/Cu (+/- PGM) mineralization associated with substantial sulphide volumes across multiple Ni/Cu zones."

The company has scheduled Borehole Electromagnetic (BHEM) geophysical surveying to help guide follow-up drilling at the target.

Babylon Target Geological Interpretation and Bushveld Analogue

The Babylon target sits at the base of the Luanga Mafic-Ultramafic Complex in the North Sector, associated with a large magnetic anomaly, a strong electromagnetic conductor and a gravity high; all geophysical signatures consistent with sulphide-rich bodies at depth. The sulphide minerals identified in drilling include pyrrhotite (an iron sulphide), pentlandite (the principal nickel-bearing mineral) and chalcopyrite (the copper-bearing mineral). Localised concentrations of chromite, a chromium mineral, are also present in close association with the sulphides, marking this as texturally and chemically distinct from other sulphide occurrences at Luanga.

Management draws a geological parallel to the Bushveld Igneous Complex (BIC) in South Africa, where pipe-like nickel-bearing and PGM intrusions occur in the lower ultramafic footwall sequence. The Babylon target appears to occupy a similar geological position at Luanga, sitting at the base of a mafic-ultramafic intrusion and spatially associated with the footwall sequence beneath the main stratiform PGM mineralisation.

Chairman and CEO Luis Azevedo added:

"We have been highlighting the potential for Ni/Cu sulphide deposits at Luanga and the surrounding areas of the Luanga Mafic-Ultramafic Complex since we first discovered the PGM deposit, calling it our Bushveld Analogue, so these results are very encouraging for this part of our exploration."

The Babylon target remains open along strike and at depth, with BHEM surveying planned to refine the next round of drill targets.

Expanded Ni/Cu and Cu/Au Exploration Pipeline Beyond the PGM Deposit

Bravo is advancing exploration on multiple fronts within the Luanga Project, targeting both near-deposit nickel-copper zones and a broader copper-gold programme within the same project footprint.

Chairman and CEO Luis Azevedo stated:

"These results expand our pipeline of Luanga-related exploration prospects beyond the PGM+Au+Ni deposit itself. At the same time, our fully funded Cu/Au-focused exploration activities are also ramping up, with the commencement of a 50km IP survey program, led by our experienced Copper Division team."

On the processing side, management noted that magmatic nickel-copper sulphides at Babylon may be amenable to treatment in the same flotation plant being considered for the Luanga PGM resource, subject to minor modifications. This observation is preliminary and subject to further metallurgical testwork.

Bravo has completed 404 drill holes totalling over 85,900 metres at Luanga to date. Assay results remain pending for 31 holes and six exploration trenches. The project currently hosts three categories of exploration targets: stratiform PGM, magmatic nickel-copper, and IOCG-style (iron oxide copper-gold) mineralisation.

Outlook

Bravo's near-term programme includes BHEM surveying at the Babylon target to refine drill targets, followed by additional drilling to test extensions of the nickel-copper mineralisation along strike and at depth. The 50-kilometre IP survey for the copper-gold programme is already underway. Pending assay results from 31 outstanding drill holes and six trenches are expected to provide further data in the near term. These activities are directed at defining the extent of multiple mineralised systems identified within the Luanga Project area.
