Bravo’s North Sector Emerges as Second Thick, High-Grade Centre of Gravity for the Luanga PGM+Au+Ni Deposit

 

 

 

 

 

Highlights include 69m at 3.8g/t PGM+Au including 5m at 25.4g/t PGM+Au, 45m at 5.0g/t PGM+Au, and 24.9m at 5.9g/t PGM+Au, 0.12% Ni

 

Bravo Mining Corp. (TSX-V: BRVO) (OTCQX: BRVMF),  has received assay results from fifteen diamond drill holes from the North Sector at its 100% owned Luanga palladium + platinum + rhodium + gold + nickel deposit, located in the Carajás Mineral Province, state of Pará, Brazil.

 

 

“The numerous thick high-grade drill intercepts from the North Sector of the Luanga deposit has significantly enhanced the resource potential in this area, thus establishing a second centre of gravity for the Luanga deposit,” said Luis Azevedo, Chairman and CEO. “In the Luanga deposit mineral resource estimate (“MRE”. See press release October 22, 2023), the Central Sector was seen to host a large proportion of the mineral resources, largely due to the concentration of historical holes and Bravo drilling. In contrast, the North Sector had only seen limited drilling at the time of the MRE. However, Bravo’s recent drilling, has consistently intercepted thicker zones of higher-grade mineralization within 150m of surface, as illustrated by the sections in this press release.”

 

Highlights Include:

  • Drilling in the North Sector continues to show improvements in both grade and thickness compared to historic drilling in this sector.
  • Mineralization intersected to date (see Sections 1 and 2) lies within 150m of surface and is open to further extension at depth.
  • The North Sector at the Luanga deposit is now recognised as a second centre of gravity of multiple thick high grade mineralized zones.
  • The current round of BHEM (bore-hole electromagnetic) surveying is close to completion. Drilling has recommencing at T5, testing new conductors along strike defined by this work. This will be followed by drilling at new and re-evaluated HeliTEM targets.

Luanga Drilling Update

 

Results from fifteen diamond drill holes have been received from the North Sector of the Luanga PGM+Au+Ni deposit. All the drill holes reported herein are angled holes (-60 degrees), towards an azimuth of 090°. Together, this set of drill holes comprise a total of 3,212.45 metres of diamond drilling.

 

Section 1 (Figure 1) in the North Sector shows infill and step-out drilling, with DDH24LU249 being the deepest drill hole on the section, exhibiting a wide zone of mineralization, open at depth, within 150m from surface, and consistently increasing in grade from DDH22LU090 to DDH24LU247 to

DDH22LU086 to DDH24LU249. Trenching (TR23LU024) in this area also demonstrates the significant volume of near surface oxide mineralization. These results continue to bode well for potential future MRE updates. In comparison, the Central Sector has been defined to depths of up to 400m below surface, more than twice the depth of current drilling in the North Sector. The addition of a second centre of gravity for the Luanga PGM+Au+Ni deposit has potential to enhance future project economics, as and when demonstrated, mineralization could potentially be extracted from shallower depths for longer periods.

 

Section 2 (Figure 2) is an infill section in the North Sector. Drilling also shows evidence of increasing thickness at depth, again with mineralization defined to date less than 150m from surface and still open at depth. As with Section 1 and in comparison, to the Central Sector, there is still significant potential to extend mineralization to depth while remaining potentially amenable to open pit exploitation, subject to future economic studies. Furthermore, Section 2 shows high volumes of mineralization in comparison to the volume of unmineralized material, demonstrating the potential for relatively low strip ratios in these areas.

 

HeliTEM (Helicopter borne EM) and Copper/Gold Exploration Update

 

Exploration is progressing on both BHEM targets and HeliTEM targets. The current round of BHEM surveying is close to completion. Drilling has recommencing at T5, testing new conductors defined along strike by this work. BHEM is currently in progress at T11. Following the new holes planned at T5, drilling will move to T11, followed by initial testing of new and re-evaluated HeliTEM targets.

 

Drill Results Status Update

 

A total of 311 drill holes have been completed by Bravo to date, for 66,366 metres, including 8 metallurgical holes (not subject to routine assaying). Results have been reported for 267 Bravo drill holes to date. Assay results for 36 Bravo drill holes that have been completed are currently outstanding (excluding the metallurgical holes).

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.
