BRAVO'S NORTH SECTOR EMERGES AS SECOND THICK, HIGH-GRADE CENTRE OF GRAVITY FOR THE LUANGA PGM+AU+NI DEPOSIT
Bravo Mining Corp. has received assay results from 15 diamond drill holes (DDH) from the North sector at its 100-per-cent-owned Luanga palladium plus platinum plus rhodium plus gold plus nickel deposit, located in the Carajas mineral province, state of Para, 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 chief executive officer. "In the Luanga deposit mineral resource estimate (MRE, see press release
Oct. 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 150 m 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 with historic drilling in this sector.
-
Mineralization intersected to date lies within 150 m of surface and is open to further extension at depth.
-
The North sector at the Luanga deposit is now recognized as a second centre of gravity of multiple thick high-grade mineralized zones.
-
The current round of BHEM (borehole electromagnetic) surveying is close to completion. Drilling has recommenced 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 15 diamond drill holes have been received from the North sector of the Luanga platinum group metals plus gold plus nickel deposit. All the drill holes reported herein are angled holes (minus 60 degrees), toward an azimuth of 090 degree. Together, this set of drill holes comprise a total of 3,212.45 metres of diamond drilling.
Section 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 150 m 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 400 m 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 plus Au plus 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 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 150 m from surface and still open at depth. As with Section 1 and, in comparison with 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 with the volume of unmineralized material, demonstrating the potential for relatively low strip ratios in these areas.
HeliTEM (helicopter-borne electromagnetic) 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 is 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 eight 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).

About Bravo Mining Corp.
Bravo is a Canadian- and Brazil-based mineral exploration and development company focused on advancing its Luanga PGM plus Au plus Ni project in the world-class Carajas mineral province of Brazil.
The Luanga project is situated on mature freehold farming land, and benefits from being in a location close to operating mines and a minin experienced work force, with excellent access and proximity to existing infrastructure, including road, rail and clean renewable hydro grid power. A fully financed 63,000-metre infill, step-out and exploration drilling and trenching program is well advanced for 2024. Bravo's current environmental, social and governance activities include planting more than 30,000 high-value trees in the project area, hiring and contracting locally, and ensuring protection of the environment during its exploration activities.
Technical disclosure
Technical information in this news release has been reviewed and approved by Simon Mottram, FAusIMM (fellow, Australia Institute of Mining and Metallurgy), president of Bravo Mining, who serves as the company's qualified person as defined in National Instrument 43-101 -- Standards of Disclosure for Mineral Projects (NI 43-101). Mr. Mottram has verified the technical data and opinions contained in this news release.
Assay methodologies and quality assurance/quality control
Samples follow a chain of custody between collection, processing and delivery to the SGS Geosol 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 SGS Geosol laboratory by Bravo staff. Additional information about the methodology can be found on the SGS Geosol website (SGS) in its analytical guides. Information regarding preparation and analysis of historic drill core is also presented in a table on-line, where the information is known.
Quality assurance and quality control (QA/QC) is maintained internally at the lab through rigorous use of internal certified reference materials, blanks and duplicates. An additional QA/QC program is administered by Bravo using certified reference materials, duplicate samples and blank samples that are blindly inserted into the sample batch. If a QA/QC 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 QA/QC sample are retested.
We seek Safe Harbor.
