Bravo Mining (TSXV:BRVO) has reported new assay results from the Luanga palladium + platinum + rhodium + gold + nickel project, from eight diamond drill holes in the Central and North Sectors. The discovery highlights the nickel sulphide potential of the project which is located in the Carajás Mineral Province, state of Pará, Brazil.
Two DDH in the Central Sector of the project identified a new zone and style of nickel sulphide mineralization. Follow-up drilling has intersected higher-grade nickel sulphide 50m to the north and south of the North Sector with some evidence indicating potential extensions toward the south.
Luis Azevedo, Chairman and CEO of Bravo Mining, commented in a press release: “Today’s results demonstrate the potential for higher-grade nickel ± copper sulphides at Luanga, underlie the existing ~8.1km strike of PGM+Au+Ni mineralization intersected in shallow historic drilling. We are at the early stages of understanding the distribution of, and controls on, this potential new style of nickel ± copper sulphide mineralization, which has now been intersected in both the North and Central Sectors,” he said. “We are very positive about the potential below Luanga and have deployed geophysical tools aimed at detecting this style of mineralization. Work is continuing and aims to drill test future geophysical targets in 2023.”
Highlights from the results are as follows:
- Highlights include 27.7m @ 0.62g/t PGM+Au, 0.62% Ni (Including 4.6m @ 1.12g/t PGM+Au plus 1.12% Ni),
- And: 25.3m @ 1.14g/t PGM+Au, 0.42% Ni, 0.34% Cu (Including 3.4m @ 2.12g/t PGM+Au, 0.84% Ni, 0.34% Cu)
- Follow up, step-out drilling to the massive nickel/copper sulphides intercepted in DDH22LU047 (August 16th, 2022 news release) intersected nickel/copper sulphides along strike, 50m to the north and to the south. Electromagnetics (EM) has identified conductors trending to the south where surface EM is ongoing.
- Drilling in the Central Sector of Luanga has intersected a new zone and style of nickel sulphide mineralization, potentially magmatic nickel sulphide mineralization. It occurs within a different rock-type than the PGM+Au+Ni mineralization at Luanga – further increasing the exploration prospectivity of Luanga. EM surveying is expected to begin shortly.
- A noticeable change in PGM chemistry (significantly higher rhodium to palladium ratio) has been identified in most assay results from both nickel sulphide zones. This also points to a new style of mineralization and provides another possible vector into higher nickel sulphide zones.
