Highlights include 122m at 2.59g/t PGM+Au, including 13m at 9.46g/t PGM+Au; 26m at 3.96g/t PGM+Au and 15m at 3.47g/t PGM+Au.
"Bravo's trenching program continues to return excellent results that are significantly better than average oxide grades reported in the existing Mineral Resource Estimate ("MRE"). In addition, the expanded lateral extent of oxide PGM+Au mineralization at the surface is likely to increase the oxide volume component of a future MRE update. The high-grade zones present within these broad intersections also continue to support our interpretation of supergene enrichment occurring in the near-surface oxide zone," said
- Results continue to demonstrate expansion of the lateral extents of surface oxide mineralization, draped over the topographic high of the outcropping Luanga mineralized trend.
- Trenching also consistently reveals the presence of supergene enrichment in the saprolite zone, situated at the base of oxidation.
- Results at the southern end of the North Sector continue to show broad distribution of oxide mineralization (TRC23LU019 with 150m at 1.38g/t PGM+Au), including zones of high-grade mineralization (26m at 3.96g/t PGM+Au).
- The first trench completed in the Central Sector (TRC23LU016) has also returned high-grade mineralization (122m at 2.59g/t PGM+Au, including 13m at 9.46g/t PGM+Au) that also further supports the intersection of high-grade supergene mineralization in nearby drill hole PPT-LUAN-FD0124 (16m at 13.13g/t PGM+Au).
- Returned grades are consistently better than MRE average grades for the oxide zone, indicating potential for increased tonnes of oxide mineralization at higher grades in future mineral resource updates.
- Trenching is planned to continue along the entire 8.1km strike length of the Luanga deposit, with work now progressing in the Central Sector.

Trenching across the strike of the outcrop/sub-crop aims to better interpret near surface mineralization and to reduce the distance/spacing between assay data points for later resource classification to the indicated category. To date, the program has been highly successful.
Results for trenches TRC23LU017 to 020 cover the southern end of the North Sector while TRC23LU016 is the first trench in the Central Sector (Figure 1). Trenching is now continuing in the Central Sector (TRC23LU013, 014, 015 results pending – Figure 1). Figure 3 shows the location of trenches reported in this press release.
Trenching results continues to highlight significant expansion in the lateral extent of shallow oxide mineralization, which extends out across the topographic ridge along the 8.1km strike length of the Luanga deposit. Results also confirm the presence of supergene enrichment in the saprolite zone (above the base of oxidation), encountering significantly higher than the MRE average grades in the oxide mineralization. The presence of supergene enrichment is also supported by intersections in shallow drillholes nearby (Figure 2 – Section 1) and reported in previous trench results (see
Figure 2 (Section 1) demonstrates the lateral extent of surface oxide mineralization, while the high-grade zone (13m at 9.46g/t PGM+Au) in TRC23LU016 supports the high-grade supergene mineralization in nearby drill hole PPT-LUAN-FD0124 (16m at 13.13g/t PGM+Au).
Trenching to date continues to be successful, and is likely to enhance future MREs, and is very cost effective. Trenching is planned to continue along the entire 8.1km strike length of the Luanga deposit, with work now progressing in the Central Sector.
The same sampling, assay laboratory procedures and QAQC protocols as applied to drill core sampling are applied to trench samples.
A total of 246 drill holes (111 in 2023) have been completed by Bravo to date, for 53,140 metres, including 8 planned twin holes and 8 metallurgical holes (not subject to routine assaying). Results have been reported for 213 Bravo drill holes to date. Results for 25 Bravo drill holes are currently outstanding (excluding the 8 metallurgical holes). A total of 18 trenches have been completed in2023, with results for 15 trenches reported and results for 3 pending.

Samples follow a chain of custody between collection, processing, and delivery to the SGS laboratory in Parauapebas, state of Pará,
Quality Assurance and Quality Control ("QAQC") 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.
