BRAVO'S TRENCHING EXTENDS CENTRAL SECTOR OXIDE MINERALIZATION
Bravo Mining Corp. has received assay results from seven trenches in the Central sector at its 100-per-cent-owned Luanga palladium plus platinum plus rhodium plus gold plus nickel deposit, located in the Carajas mineral province, state of Para, Brazil.
"Bravo's trenching program continues to return excellent results, with grades higher than the average oxide grades reported in the mineral resource estimate. In addition, the greater lateral extent of oxide PGM+Au mineralization at surface is likely to increase the volume of oxide material," said Luis Azevedo, chairman and chief executive officer of Bravo. "Furthermore, it is encouraging to see that trenching results from the Central sector continue to follow the trend observed in the North sector, with broad lateral distribution at surface, combined with supergene enrichment. With trenching now completed across more than half of the Luanga deposit, results continue to outperform expectations."
Highlights include the following.
Results from the Central sector trenches continue to demonstrate the broader lateral extent of surface oxide mineralization in comparison with the zones of primary (fresh rock) mineralization observed in drilling below the trenches (including 52 metres wide in TRC24LU007 and 51 metres wide in TRC24LU008).
Results continue to confirm the presence of supergene enrichment in the saprolite zone (above the base of oxidation), encountering grades that are generally higher than MRE average grades for oxide mineralization.
Grades in trenches further corroborate or improve upon intersections encountered by drilling in the underlying fresh rock, while higher-grade zones within trenches, such as TRC24LU001 (39.6 m at 5.41 grams per tonne PGM+Au) also validate or surpass the high-grade intersections encountered by prior drilling.
Results to date suggest more tonnes of oxide at higher grades, assuming similar cut-off grades to prior estimates.
Trenching is planned to cover the entire 8.1-kilometre strike length of the Luanga deposit and, with work nearly complete in the Central sector, only the Southwest sector and a small portion of the North sector remain.
Outside of the main PGM+Au+Ni deposit, the project remains prospective for copper plus gold plus or minus nickel discoveries with drilling in progress at T5 and T6. This will be followed by drilling at new HeliTEM targets.
Luanga trenching program
Trenching across the strike of the mineralization in the Central sector aims to better interpret near-surface mineralization, reduce the distance/spacing between assay data points for later resource classification, and define the lateral extent or dispersion of surface oxide mineralization. The program continues to be successful, demonstrating that surface enrichment of surface oxide material is not confined to areas of more pronounced topographic relief, like the North sector of the Luanga deposit. Initially, the Central sector, with its flatter terrain, was thought to have less potential for supergene enrichment and/or extensive lateral dispersion due to its lower topographic relief. However, this is now proved not to be the case as results from a further seven adjacent trenches continue to demonstrate in the core of the Central sector. Further, the highest grades in the oxides appear to correlate with the updip projection of the Main sulphide zone.
Recent results continue to confirm the presence of supergene enrichment in the saprolite zone (above the base of oxidation), encountering grades that are generally higher than MRE average grades for oxide mineralization and higher than grades reported in drilling intersections directly below the trenches. These new trench results support results reported previously for the first seven trenches at the Central sector (see
April 15, 2024). Like previous Central sector trenching, results again show significantly greater dispersion as compared with the mineralized thicknesses encountered in drilling below the trenches.
Trenching is continuing to cover the entire 8.1-kilometre strike length of the Luanga deposit, with work close to completion in the Central sector, which will leave only the Southwest sector and a small portion of the North sector to complete the trenching program.
The same sampling, assay laboratory procedures and quality assurance/quality control protocols as applied to drill core sampling are applied to trench samples.
Drill results status update
A total of 315 drill holes have been completed by Bravo to date, for 67,168 metres, including eight metallurgical holes (not subject to routine assaying). Results have been reported for 267 Bravo drill holes to date. Assay results for 40 Bravo drill holes that have been completed are currently outstanding (excluding the metallurgical holes).
About Bravo Mining Corp.
Bravo is a Canadian and Brazil-based mineral exploration and development company focused on advancing its Luanga PGM+Au+Ni project in the world-class Carajas mineral province of Brazil. The project is also prospective for copper-gold plus or minus nickel discoveries, as seen by recent drill intercepts in initial testing of geophysical targets outside of the main Luanga PGM+Au+Ni deposit (see news releases dated
May 28, 2024,
and
June 10, 2024).
The Luanga project is situated on mature freehold farming land and benefits from being in a location close to operating mines and a mining-experienced work force, with excellent access and proximity to existing infrastructure, including road, rail and clean renewable hydro grid power. A fully financed 63,000-metre infill, stepout and exploration drilling and trenching program is well advanced for 2024. Bravo's current environmental, social and governance activities include planting more than 30,000 high-value trees in the project area and surrounding communities, hiring and contracting locally, and ensuring protection of the environment during its exploration activities.
