BRAVO'S TRENCHING PROGRAM EXPANDS HIGH GRADE OXIDE PGM+AU MINERALIZATION
Bravo Mining Corp. has received assay results from nine trenches in the northern, central and southwestern sectors at its 100-per-cent-owned Luanga palladium-plus-platinum-plus-rhodium-plus-gold-plus-nickel (PGM-plus-Au-plus-Ni (platinum group metal, gold and nickel)) project, located in the world-class Carajas mineral province, state of Para, Brazil.
"Trenching has consistently shown a greater lateral extent to the oxide PGM-plus-Au mineralization at surface, which includes areas with significantly higher grades. The continued success of trenching results suggests the potential for an increase in the volume of oxide mineralization at Luanga. Additionally, the higher-grade zones within these sections align with or enhance the grades observed in the drilling below the trenches, further supporting our interpretation of supergene enrichment," said Luis Azevedo, chairman and chief executive officer of Bravo.
Highlights include:
- Trenching across the strike of the Luanga PGM-plus-Au-plus-Ni deposit has been successfully completed, covering all three sectors (northern, central and southwestern), and results are ready for inclusion in the upcoming mineral resource update.
-
Results highlight a significant expansion in the lateral extent of shallow oxide mineralization, extending across the topographic highs, along the entire 8.1-kilometre (km) strike length of the Luanga deposit, while also confirming the presence of supergene enrichment in the saprolite zone.
- Grades encountered in the trenches are often comparable with, or higher than, the grade of oxide mineralization and often exceed the grade of the underlying fresh rock.
-
Trench TRC24LU037 in the northern sector was positioned across historical hole FD0136 (17 metres (m) at 36 grams per tonne (g/t) PGM plus Au) and Bravo's twin hole DDH22LU043 (17 m at 38 g/t PGM plus Au). The trench results align well with the underlying drill intercepts, with 97 m at 4.86 g/t PGM plus Au, including 24 m at 14.36 g/t, dispersed over this area.
- Trenching has consistently shown evidence of mushrooming of the oxide mineralization and supergene enrichment. This demonstrates the potential for volumetric growth in oxide mineralization in the future.
Luanga trenching program
Trenching across the strike of the Luanga PGM-plus-Au-plus-Ni deposit aims to improve the interpretation of near-surface mineralization and to reduce the distance/spacing between assay data points with the objective of supporting mineral resource classification to the indicated category. The program has continued to be successful in meeting Bravo's objectives, with trenching now complete over all three sectors of Luanga (northern, central and southwestern).
Trenches TRC24LU037, TRC24LU039 and TRC24LU041 cover the southern end of the northern sector. Trenches TRC24LU033 and TRC24LU034 are at the southern end of the central sector. Trenches TRC24LU047, TRC24LU050, TRC24LU052 and TRC24LU054 are in the southwestern sector. The current trenching program is now complete.
Trenching results continue to highlight significant expansion in the lateral extent of shallow oxide mineralization, which extends down both slopes of the topographically elevated areas, along the entire 8.1 km strike length of the Luanga PGM-plus-Au deposit. Results also continue to confirm the presence of enrichment in the saprolite zone (above the base of oxidation), encountering grades that are equal or better-than-average grades of oxide mineralization in surrounding drill holes. In the northern sector, trench TRC24LU037 passes above historical hole FD0136 (17 m at 36 g/t PGM plus Au) and the Bravo twin hole to this, 22LU043 (17 m at 38 g/t PGM plus Au). The Bravo twin hole replicated the historical hole extremely well, while the new trench result closely reflects the drill results below, with
97 m at 4.86 g/t PGM plus Au (including
24 m at 14.36 g/t) dispersed over this area.
Trench TRC24LU037 shows similar high grades, but now dispersed over a much larger area, with
97 m at 4.86 g/t PGM plus Au (including
24 m at 14.36 g/t). This mushrooming of oxide mineralization demonstrates the potential for volumetric growth in future oxide mineralization that was not possible to define by drilling alone.
Trenching has now been completed over the 8.1 km strike length of the Luanga deposit.
The same sampling, assay laboratory procedures and QA/QC (quality assurance/quality control) protocols as applied to drill core sampling are applied to trench samples.
Luanga drilling and trenching status
A total of 345 drill holes have been completed by Bravo to date, for 73,675.65 m, including eight metallurgical holes (not subject to routine assaying). Results have been reported for 304 Bravo drill holes to date. Assay results for 33 Bravo drill holes that have been completed are currently outstanding (excluding the metallurgical holes). A total of 45 trenches have been completed to date (for 9,065.73 m), with results for all trenches reported.
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, as well as its Cu-Au (copper and gold) exploration opportunities in the world-class Carajas mineral province, Para state, Brazil.
Bravo is one of the most active explorers in Carajas. The team, comprising local and international geologists, has a proven record of PGM, nickel and copper discoveries in the region. It has successfully taken a past IOCG (iron ore, copper and gold) greenfield project from discovery to development and production in the Carajas.
The Luanga project is situated on mature freehold farming land and benefits from being located close to operating mines and a mining-experienced work force, with excellent access and proximity to existing infrastructure, including road, rail, ports and hydroelectric grid power. A fully financed 70,000-plus m infill, stepout and exploration drilling and trenching program was completed in 2024. Bravo's current environmental, social and governance activities includes planting more than 30,000 high-value trees in and around the project area, while hiring and contracting locally.
Technical disclosure
Technical information in this news release has been reviewed and approved by Simon Mottram, FAusIMM (fellow of the Australasian 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. Mr. Mottram has verified the technical data and opinions contained in this news release.
Schedule 2: assay methodologies and QA/QC
Samples follow a chain of custody between collection, processing and delivery to the SGS 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 laboratory by Bravo staff. Additional information about the methodology can be found on the SGS Geosol website in its analytical guides. Information regarding preparation and analysis of historic drill core is also presented in an attached table, where the information is known.
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.
