Bravo's Infill Drilling Continues to Intercept Magmatic Nickel Sulphides at Depth at Luanga

04.04.2023  |  CNW

Highlights include 8.7m @ 1.46g/t PGM+Au, 0.46% Ni (Including 2.0m @ 4.11g/t PGM+Au, 1.68% Ni),

And: 4.9m @ 1.13g/t PGM+Au, 0.56% Ni (Including 0.9m @ 3.06g/t PGM+Au, 2.05% Ni)

VANCOUVER, April 4, 2023 - Bravo Mining Corp. (TSXV: BRVO) (OTCQX: BRVMF), ("Bravo" or the "Company") announced that it has received assay results from five diamond drill holes ("DDH") in the North Sector, drilled along strike from the previously announced magmatic nickel (± copper) sulphide intercepts drilled as part of the Phase 1 program (see news releases dated February 14th, 2023 and August 16th, 2022), at its 100% owned Luanga palladium + platinum + rhodium + gold + nickel project ("Luanga" or "Luanga PGM+Au+Ni Project"), located in the Carajás Mineral Province, state of Pará, Brazil.

"With infill drilling alone continuing to intercept magmatic nickel sulphides at depth, the Company is accelerating its plans for exploration with the commission of a detailed airborne Electromagnetic ("EM") survey over the entire Luanga project area (7.810ha)" said Luis Azevedo, Chairman and CEO of Bravo. "While our understanding of the distribution and controls on magmatic nickel (± copper) sulphide mineralization is still in its early stages, we continue to see patterns and evidence that suggest potential at depth and in the ultramafic footwall sequence, and perhaps these might lead towards a common more central location below the Luanga intrusion. Fast-tracking a comprehensive geophysics program could unlock the potential below Luanga, and greatly accelerate the Phase 2 exploration program in 2023," he said.

Highlights Include:

  • Infill drilling continues to intercept magmatic nickel sulphides at depth at Luanga, further reinforcing the need to accelerate focused nickel exploration below the known PGM+Au mineralization at Luanga.
  • Drilling in the North Sector of Luanga has intercepted the continuation of magmatic nickel sulphides, below the depth of existing historical drilling.
  • A significant detailed geophysical program is being commissioned to accelerate the ongoing Phase 2 program.
  • A detailed HeliTEM (Helicopter airborne EM) survey over the entire Luanga project is the key component of the geophysics program.
  • Detailed gravity and ground magnetic surveys have also commenced, prioritizing prospective magmatic nickel sulphide targets within favourable geology, and potential feeder zone target(s).

Notes:

All intercepts were in fresh rock.


Given the orientation of the hole and the mineralization, the intercepts are estimated to be 85% to 100% of true thickness.


* Bravo's nickel grades are sulphide nickel, and do not include non-recoverable silicate nickel, unlike historic total nickel assays.


Magmatic Nickel Exploration Program

Given the increasing number of magmatic nickel sulphide intercepts at depth in the infill drilling program, and the recent commencement of Phase 2 extensional drilling below this mineralization, Bravo has elected to accelerate its exploration program targeting magmatic nickel (± copper) sulphides at Luanga.

The Company has engaged a geophysical contractor to complete a HeliTEM survey over the entire Luanga project. The EM survey is planned at a detailed line spacing of 150m and is expected to be carried out in Q2, 2023.

A ground magnetic survey is underway, with 35 line/km completed to date utilizing Bravo's own equipment. A detailed gravity survey has commenced using the Company's new CG-6 gravity meter and base station (Figure 1). These surveys prioritize prospective nickel stratigraphy and potential feeder zone target/s.

North Sector Magmatic Nickel Sulphides in Infill Drilling

Infill drilling in the North Sector (Figure 2) continues to intercept magmatic nickel sulphides at depth (Section - Figure 4). Some infill drilling by Bravo has been deeper than historical drilling on nearby sections, perhaps explaining the absence of observed nickel sulphides in historical drilling.

Figure 3 shows the location of drill results in this news release, demonstrating that higher-grade magmatic nickel sulphides are vectoring to the south, towards the center of the intrusion, whilst passing under the depth extent of the shallower drilling on historical drill sections.

The Phase 2 program has commenced, with 21,500 meters of drilling planned, focused on extensional drilling to depth (below the known mineralization) and exploration of new targets. The extensional drilling seeks to follow the Luanga PGM+Au deposit down dip while, at the same time, extending holes to depths sufficient to test the interface between the PGM host sequence and the ultramafic footwall sequence. The accelerated geophysical program aims to generate magmatic nickel sulphide exploration targets and examine the entire Luanga project area, including outside the mineralized footprint identified to date.

DDH22LU088 and DDH22LU098 shown in the section below (Figure 4), encountered magmatic nickel sulphides close to the bottom of the drill holes, deeper than tested by nearby historical drilling. Current exploration targeting thus recognizes the magmatic nickel sulphide potential at depth, closer to the ultramafic footwall sequence and within the ultramafic footwall sequence, and vectoring towards the center of the Luanga intrusion which ideally should be closer to a feeder zone location. Similarly magmatic nickel sulphides encountered in the Central Sector also appear to vector towards the center of the Luanga intrusion, which aligns with the Company's geological model for Luanga.

Luanga Drill Program Progress

A total of 165 drill holes (30 in 2023) have been completed by Bravo to date, for 28,674 metres, including all 8 planned twin holes and all 8 metallurgical holes (not for routine assaying).

Results have been reported for 117 Bravo drill holes to date. Excluding the 8 metallurgical holes, results for 40 Bravo drill holes are currently outstanding.

Luanga's maiden NI 43-101 MRE is on-track for H2/2023.

Schedule 2: Assay Methodologies and QAQC

Samples follow a chain of custody between collection, processing, and delivery to the ALS laboratory in Parauapebas, state of Para?, Brazil. The drill core is delivered to the core shack at Bravo's Luanga site facilities and processed by geologists who insert certified reference materials, blanks, and duplicates into the sampling sequence. Drill core is half cut and placed in secured polyurethane bags, then in security-sealed sacks before being delivered directly from the Luanga site facilities to the Parauapebas ALS laboratory by Bravo staff. Additional information about the methodology can be found on the ALS global website (ALS) in the analytical guides.

Quality Assurance and Quality Control ("QAQC") is maintained internally at the lab through rigorous use of internal certified reference materials, blanks, and duplicates. An additional QAQC program is administered by Bravo using certified reference materials, duplicate samples and blank samples that are blindly inserted into the sample batch. If a QAQC sample returns an unacceptable value an investigation into the results is triggered and when deemed necessary, the samples that were tested in the batch with the failed QAQC sample are re-tested.
