Bravo Mining Corp. has received assay results from the two drills hole at the T5 target, and intersected sulphide mineralization in drilling at the T11" electromagnetic (EM) target at its 100% owned Luanga Project ("Luanga") which includes the Luanga palladium + platinum + rhodium + gold + nickel deposit, in the Carajás Mineral Province, Brazil. Hole DDH2405T003 at T5 Target, located 50m west and along strike of previously reported high-grade hole DDH2405T002, intersected 5.2m of semi-massive/breccia hosted copper sulphide mineralization grading 3.1% Cu and 1.1g/t Au.
Copper-gold mineralization at T5 Target remains open at depth and along strike. BHEM surveys at T5 is in progress, including holes DDH2405T003, 04, 05 and 06 which will position Bravo for the August drill program. At T11, drill hole DDH2411T002 intersected four significant sulphide-rich intervals within a broader alteration zone.
Pyrrhotite > pentlandite >> chalcopyrite is present as patches/veins, locally massive to semi-massive textures. BHEM in progress. Assay results have been received from diamond drill holes DDH2405T003 and DDH2405T005 at the T5 target, located 1km east of the Luanga PGM Deposit.
Drill hole DDH2405T006 has also been completed and intersected strong alteration interpreted to be proximal to the mineralization (assays pending). BHEM was completed on the pilot hole (DDH2311T001) at HeliTEM target "T11". BHEM anomalies defined from this drill hole indicated that the targets were deeper, below the drill hole.
These refined targets were then successfully tested by DDH2411T002, which intersected sulphide mineralization. Together, this drilling of HeliTEM and BHEM anomalies comprises a total of 1,179 metres. Bravo continues to conduct systematic first-pass drilling, coupled with BHEM, on the priority EM conductors identified by the HeliTEM survey.
Although these modelled HeliTEM conductors have a lower degree of locational accuracy, they are sufficiently defined to position first-pass drilling proximal to the conductor's location. From there, BHEM provides more precise location of EM anomalies for drill testing. Of the 17 priority EM anomalies identified in the HeliTEM survey (see press release September 11, 2023), Bravo had narrowed this list to 11 high priority conductors that warranted follow-up drilling of predominantly off-hole BHEM conductors.
T5, T6, T16 and now T11 are four of these 11 HeliTEM targets. Drill hole DDH2405T003 intersected 5.2m (grading 3.1% Cu, 1.1g/t Au) of breccia-hosted copper sulphide mineralization, at the T5 target. Like hole DDH2405T002, located 50m to the east, mineralization is interpreted to be consistent with typical copper/gold mineralization seen in the Carajás Mineral Province, and unrelated to the Luanga PGM+Au+Ni Deposit.
DDH2405T006 has been completed down-dip of (below) hole DH2405T002, intersecting significant hydrothermal alteration consistent with that expected proximal (close) to the mineralization. Drilling is paused while BHEM is completed on drill holes DDH2405T003, DDH2405T004, DDH2405T005 and DDH2405T006 to better establish the dip/plunge of mineralization before the next round of drilling. DDH2405T005, located up dip of (above) DDH2405T002, intersected weathered mineralization in the oxidized zone, where mineralization is interpreted to be weathered away.
The T11 target is located proximal to the ultramafic footwall of the Central Sector of the Luanga PGM+Au+Ni deposit. The pilot drill hole targeting the HeliTEM anomaly was shown to be too shallow and was drilled up-dip of the EM conductors which were subsequently better defined by BHEM to be deeper. DDH2411T002 targeted the center of this group of 10 conductors at a more appropriate depth, successfully intersecting four zones of mineralization within an approximately 190m wide hydrothermal alteration zone.
At 96m depth drill hole DDH2411T002 intersects the ultramafic footwall of the Luanga deposit, intersecting an Fe-Ca alteration system which consists of magnetite, grunerite, hornblende, actinolite, biotite and almandine. This mineralogical assemblage is similar to other IOCG-style mineralized systems that occur within the Carajás Mineral Province, and is likely unrelated to the primary Luanga PGM deposit mineralization which is at a stratigraphically higher level. BHEM will be completed on DDH2411T002 prior to commencing follow-up drilling.
A total of 304 drill holes have been completed to date by Bravo, for 65,113 metres, including 8 metallurgical holes (not subject to routine assaying). Results have been reported for 252 Bravo drill holes to date. Assay results for 44 Bravo drill holes that have been completed are currently outstanding (excluding the metallurgical holes).
Bravo plans to extend the current EM drilling program from 3,000m to 8,000m, to continue drilling testing and follow up drilling of EM anomalies.
