BRAVO'S TRENCHING PROGRAM CONTINUES TO EXPAND OXIDE PGM+AU MINERALIZATION
Bravo Mining Corp. has received assay results from eight trenches in the central and northern sectors at its 100-per-cent-owned Luanga palladium-plus-platinum-plus-rhodium-plus-gold-plus-nickel project (PGM (platinum group metal) plus gold (Au) plus nickel (Ni)), located in the world-class Carajas mineral province in the state of Para, Brazil.
"Trenching has uncovered a wider lateral extent of oxide PGM-plus-Au mineralization at surface, which includes areas with higher grades. These findings suggest a potential 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 trench lines, 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 continues to be successful, with work to date almost complete in the northern and central sectors. Results highlight significant expansion in the lateral extent of shallow oxide mineralization, which extends across the topographic highs, along the entire 8.1-kilometre (km) strike length of the Luanga deposit tested to date.
- Results confirm the presence of enrichment in the saprolite zone, while encountering grades that are on par or better than the grade of the oxide mineralization and often improve upon intersections encountered by drilling in the underlying fresh rock.
- In the northern sector, trench TRC24LU043, where more pronounced topography again provides clearer evidence of supergene enrichment, returned 156.5 metres (m) at 1.01 grams per tonne (g/t) PGM plus Au, including five m at 5.24 g/t PGM plus Au.
- This mushrooming of oxide mineralization in the supergene zone demonstrates the potential for volumetric growth in future volumes of oxide mineralization.
- Drilling continues at the T5 target, with assays pending for six drill holes, all of which have all intersected copper sulphide mineralization on the eastern end of T5.
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 continues to be successful in meeting Bravo's objectives, with trenching almost complete in the northern and central sectors, and only eight trenches remaining to be completed this year.
Trenches TRC24LU030, TRC24LU031A+B, TRC24LU032, TRC24LU035 and TRC24LU036 cover the southern extent of the central sector, while trenches TRC24LU043 and TRC24LU044 are at the southern extent of the northern sector. Trenching continues in the central sector, with only one trench to complete before commencing in the southwestern sector.
Trenching results continue to highlight significant expansion in the lateral extent of shallow oxide mineralization, which extends across 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) but to lesser degree in the central sector, where the topographic highs are less exaggerated, encountering grades that are equal or better than average grades of oxide mineralization in surrounding drill holes. In the northern sector, trench TRC24LU043, where more pronounced topography demonstrates clearer evidence of supergene enrichment, returned a result of 156 m at 1.01 g/t PGM plus Au, including five m at 5.24 g/t PGM plus Au.
Mushrooming of oxide mineralization in the supergene zone demonstrates the potential for volumetric growth in future oxide mineralization that it was not possible to define by drilling alone.
Trenching continues along the entire 8.1 km strike length of the Luanga deposit, with work finalizing the central sector and progressing to completion in the southwestern sector.
The same sampling, assay laboratory procedures, and quality assurance and quality control (QA/QC) protocols as applied to drill core sampling are applied to trench samples.
Luanga drilling and trenching status
A total of 332 drill holes have been completed by Bravo to date, for 70,577.75 metres, including eight metallurgical holes (not subject to routine assaying). Results have been reported for 267 Bravo drill holes to date. Assay results for 57 Bravo drill holes that have been completed are currently outstanding (excluding the metallurgical holes). A total of 37 trenches have been completed to date (for 7,623.08 metres), with results for 36 trenches reported and results for one trench pending.
T5 target -- exploration update
Drilling continues at the T5 target, located one km east of the Luanga PGM-plus-Au deposit. Assays are pending for drill holes DDH2405T012, DDH2405T013, DDH2405T014, DDH2405T015, DDH2405T016 and DDH2405T017, all of which have intersected copper sulphide mineralization on the eastern end of T5.
About Bravo Mining Corp.
Bravo is a Canadian- and Brazil-based mineral exploration and development company focused on advancing its PGM and copper-gold Luanga project 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. The team 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 and hydro grid power. A fully financed plus-70,000-metre infill, stepout and exploration drilling and trenching program is well advanced for 2024. Bravo's current environmental, social and governance activities includes planting more than 30,000 trees in and around the project area, hiring and contracting locally, and working to ensure 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 of the Australia Institute of Mining and Metallurgy), president of Bravo, 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 in the 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 the 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.
