Bravo Intercepts Further High-Grade Copper-Gold Mineralization at T5 Intercept of 8.75m at 9.48% Cu and 2.1g/t Au

 

 

 

 

Copper-Nickel Mineralization Intersected in First Drill Hole at T16 target Intercept of 1.29m at 2.39% Cu, 1.17% Ni

 

Bravo Mining Corp. (TSX-V: BRVO) (OTCQX: BRVMF), has received assay results from the second drill hole at the “T5” target and from the first drill hole in the “T16” electromagnetic target. This is the third HeliTEM (Helicopter based electromagnetics) target to be drilled at the 100% owned Luanga Project which includes the Luanga palladium + platinum + rhodium + gold + nickel deposit, in the Carajás Mineral Province, state of Pará, Brazil.

 

“Exploration continues to yield very encouraging results, both from ongoing drilling at T5, and now at another HeliTEM geophysical target, T16. At T5, we continue to intersect high-grade Iron Oxide Copper Gold style (“IOCG-style”) mineralization, which is a well documented style of mineralization in the Carajás, while at T6 and now T16, we potentially see two distinctly different styles of mineralization that appear magmatic related,” said Luis Azevedo, Chairman and CEO. “Whilst we are encouraged with these discoveries, we are still in the early days of the exploration program and these initial successes suggest potential for yet more discoveries given the number of anomalies Bravo has yet to test or follow up.” he said. “We also need to integrate these findings and new styles of mineralization into our regional models to reassess all the other HeliTEM anomalies that were previously set aside before we encountered IOCG-style mineralization at T5. The Carajás Mineral Province is an exceptionally fertile area and Luanga sits within a corridor containing several significant IOCG deposits/operations. Bravo looks forward to continuing our exploration efforts in this prolific region.”

 

Highlights Include:

  • Hole DDH2405T004 at Target T5, located 50m east and along strike of previously reported high-grade hole DDH2405T002, intersected 8.75m of massive/semi-massive/breccia hosted high-grade copper sulphide mineralization grading 9.5% Cu and 2.1g/t Au (Figures 1 and 2).
  • High-grade copper-gold mineralization at Target T5 remains open at depth and along strike.
  • Hole DH2405T006 is now in progress at T5, below (down-dip of) discovery hole DH2405T002.
  • Initial drill hole DDH2416T001 at Target T16 HeliTEM target intersected 1.29m of breccia hosted sulphide copper-nickel mineralization (Figure 5) grading 2.39% Cu, 1.17% Ni.
  • Mineralization at T16 is potentially a different style of mineralization, one not previously observed at Luanga.
  • Drilling will continue at T5, while a second drill rig will commence follow-up drilling on BHEM (Borehole Electromagnetic) anomalies at T6, T11, T15, T16 and T17.
  • As a result of the initial positive results, the EM-target drilling has increased from an initial 3,000m to 8,000m and may increase further, depending on results.

 

Exploration Drilling Update

 

Assay results have been received from diamond drill hole DDH2405T004 at the T5 target, 1km east of the Luanga Deposit, and from diamond drill hole DDH2416T001 at the T16 HeliTEM target, 1.2 km south of Luanga’s PGM+Au+Ni-rich Central Sector. BHEM has been completed on hole DDH2416T001 at T16. Together, this latest drilling comprises a total of 371 metres.

 

Bravo continues to conduct systematic first-pass drilling, coupled with BHEM, on the priority EM conductors identified by the HeliTEM survey. Although these modelled HeliTEM conductors have a lower degree of locational accuracy, they are sufficiently defined to position first-pass drilling proximal to the conductor’s location. From there, BHEM provides more precise location of EM anomalies for drill testing. Of the 17 priority EM anomalies identified in the HeliTEM survey (see press release September 11, 2023), Bravo has narrowed this list to 11 high priority conductors that warrant follow-up drilling of predominantly off-hole BHEM conductors. T5, T6 and now T16 are three of these 11 HeliTEM targets.

 

Drilling will continue at T5, while a second drill rig will commence to follow-up drilling on BHEM anomalies at T6, T11, T15, T16 and T17, before moving to new targets to implement initial drilling/BHEM.

 

T5 Target

 

Figure 2 shows the mineralization intersected in DDH2405T004, the second hole at the T5 target, and located 50m east and along strike of previously reported hole high-grade copper-gold mineralization in DDH2405T002 (see press release May 28, 2024) which intercepted 11.48m at 14.3% Cu, 3.3g/t Au including 2.9m at 22.9% Cu, 3.6g/t Au.

 

Drill hole DDH2405T004 intersected 8.75m (grading 9.48% Cu, 2.1g/t Au) of massive/semi-massive/breccia hosted copper sulphide mineralization, at the T5 target. Like hole DDH2405T002, located 50m to the west, mineralization is interpreted to be consistent with typical Carajás IOCG-style hydrothermal mineralization (also supported by preliminary chemistry from handheld XRF spectrometer), further indicating T5 as IOCG-style and unrelated to the Luanga Deposit.

 

DDH2405T006 is now in progress, below (down-dip) DH2405T002, with additional drilling planned along strike and up and down dip.

Hole DH2405T003, drilled 50m west of DH2405T002 (Figure 4) intersected breccia hosted copper sulphides (Figure 3). Like DDH2405T002 and 004, this core also contains semi-massive/breccia IOCG-style copper sulphide mineralization, confirming continuity of the sulphide mineralization along strike. Assays are pending.

 

DH2405T005, located up dip of DH2405T002 (Figure 4), intersected oxidized mineralization with interpreted ex-massive sulphides present as weathered oxides (assays pending). Mineralization at T5 remains open along strike, and up-dip/down dip from the intercepts reported here.

 

T16 Target

 

T16 is located 1km south of the PGM+Au+Ni mineralization in the Central Sector and is hosted in meta-diorite below the Luanga footwall ultramafic sequence. Figure 5 shows the intersected mineralization, which consists of 1.3m of breccia hosted sulphides, mainly pyrrhotite, generating a strong EM response. This first drill hole at T16 targets the HeliTEM anomaly and appears to have successfully intersected the EM conductor. BHEM data indicates that the conductor extends at depth, below DDH2416T001.

 

T16 has a clear association between Ni-Cu and Pt-Pd-Au, which is very different to both T5, which is essentially chalcopyrite (Cu sulphide) associated, and T6, which is essentially pyrrhotite (Fe sulphide) associated. This Pt-Pd-Au association indicates that T16 may have a contribution from the Luanga Deposit. The low Ni/Cu ratio (~0.5) and Au/Pd ratio (~0.75) are quite distinct from both magmatic and remobilized sulphides previously seen associated with the Luanga Deposit. Mineralization at T16 is potentially a different style of mineralization not previously observed at Luanga.

 

Follow-up drilling will target the BHEM conductor at a greater depth, below DDH2416T001.

Drill Results Status Update

 

A total of 298 drill holes have been completed to date by Bravo, for 63,672 metres, including 8 metallurgical holes (not subject to routine assaying). Results have been reported for 249 Bravo drill holes to date. Assay results for 41 Bravo drill holes that have been completed are currently outstanding (excluding the metallurgical holes). Bravo plans to extend the current EM drilling program from 3,000m to 8,000m, to follow up identified EM anomalies, continue to systematically evaluate T5, and other high-priority conductors defined by HeliTEM and subsequent BHEM surveys. In addition to exploratory drilling on EM anomalies, ongoing drilling continues at the Luanga Deposit.

Schedule 2: Assay Methodologies and QAQC

 

Samples follow a chain of custody between collection, processing, and delivery to the SGS Geosol laboratory in Parauapebas, state of Pará, 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 SGS Geosol laboratory by Bravo staff. Additional information about the methodology can be found on the SGS Geosol website (SGS) in their analytical guides. Information regarding preparation and analysis of historic drill core is also presented in the table below, where the information is known.

 

Quality Assurance and Quality Control 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.
