Trenching Program Expands High Grade Oxide PGM+Au Mineralization
VANCOUVER - Bravo Mining Corp. has received assay results from nine trenches in the North, Central and Southwest Sectors at its Luanga palladium + platinum + rhodium + gold + nickel project, located in the World Class Carajás Mineral Province, state of Pará, Brazil.
"Trenching has consistently shown a greater lateral extent to the oxide PGM+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 CEO.
Trenching across the strike of the Luanga PGM+Au+Ni deposit has been successfully completed, covering all three Sectors (North, Central and Southwest), 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 8.1km strike length of the Luanga deposit, whilst also confirming the presence of supergene enrichment in the saprolite zone. Grades encountered in the trenches are often comparable to, or higher than, the grade of oxide mineralization and often exceed the grade of the underlying fresh rock.
Trench TRC24LU037 in the North Sector was positioned across historic hole FD0136 (17m @ 36g/t PGM+Au) and Bravo's twin hole DDH22LU043 (17m @ 38g/t PGM+Au). The trench results align well with the underlying drill intercepts, with 97m at 4.86g/t PGM+Au, including 24m at 14.36g/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.
Trenching across the strike of the Luanga PGM+Au+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 (North, Central and Southwest).
Trenches TRC24LU037, 039, and 041 cover the southern end of the North Sector. Trenches TRC24LU033 and 034 are at the southern end of the Central Sector. Trenches TRC24LU047, 050, 052 and 054 are in the Southwest 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 8.1km strike length of the Luanga PGM+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 North Sector, trench TRC24LU037 passes above historic hole FD0136 (17m @ 36g/t PGM+Au) and the Bravo twin hole to this, 22LU043 (17m @ 38g/t PGM+Au). The Bravo twin hole replicated the historic hole extremely well, while the new trench result closely reflects the drill results below, with 97m at 4.86g/t PGM+Au (including 24m at 14.36g/t) dispersed over this area.
Trench TRC24LU037 shows similar high grades, but now dispersed over a much larger area, with 97m at 4.86g/t PGM+Au (including 24m at 14.36g/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 8.1km strike length of the Luanga deposit.
Mineralized widths and grades in all 4 drill holes on this section are relatively similar, while the assay results in trench TRC24LU052 also reflect closely to the drilling. However, surface dispersion covers 123m across the topographic high, showing potential for volumetric growth while maintaining a similar grade. Again, this "mushrooming" of oxide mineralization in the supergene zone demonstrates the potential for volumetric growth in future oxide mineralization that was not possible to define by drilling alone.
Luanga Drilling & Trenching Status consists of a total of 345 drill holes have been completed by Bravo to date, for 73,675.65 metres, including 8 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 metres), with results for all trenches reported.
