VANCOUVER, June 22, 2022 - Bravo Mining Corp. ("Bravo" or the "Company") today announced that it has received assay results from two twin holes, the first two of seven that are planned at its Luanga platinum group metals (palladium + platinum + rhodium) + gold + nickel (PGM+Au+Ni) project ("Luanga"), located in the Carajás Mineral Province, state of Para?, Brazil. The results of the twin holes closely correlate with the immediately adjacent historic drill holes in both tenor and mineralized thicknesses.
"We are pleased with the results of our inaugural Luanga Phase 1 25,500m confirmation, infill and step out drill program with the receipt of the assays from two twin drill holes that confirm the immediately adjacent VALE SA drill holes," said Luis Azevedo, Chairman and CEO of Bravo. "We look forward to continuing to provide updates as our drilling and re-assay programs ramp up."
Highlights
- Assay results from two of the seven planned twin drill holes aimed at confirming results from historic VALE SA drilling have been received demonstrating a strong correlation with the historic intercept grades and thicknesses.
- Highlights of Bravo's intercepts are tabulated below, and comparisons with the historic intercepts are provided on the following pages.
HOLE-ID | From (m) | To (m) | Thickness | Pd (g/t) | Pt (g/t) | Rh (g/t) | Au (g/t) | Ni % | 4E* (g/t) | TYPE |

- *4E = palladium + platinum + rhodium + gold.
- All From To depths, and Thicknesses are downhole
- Given the orientation of the holes and the mineralization, the intercepts are estimated to range from ~70 to 100% of true thickness.
- Ox = Oxide. Sul = Sulphide. Recovery methods and results will differ based on the type of mineralization
- NA: Not Applicable as intercept is a mix of oxide and sulphide mineralization.
Twin Hole Drill Program
Of the 252 historic drill holes completed by VALE SA, seven were selected for twinning using diamond core of the same size (NQ) as the historic drill holes. To date, four twin holes have been completed aggregating 608.10m. These twin holes were designed to be spread evenly along the approximate 7km of strike of the Luanga project, testing mineralization with a range of tenor.
Bravo has received final assay results (including palladium, platinum, rhodium, gold and nickel sulphide) for the first two twin holes (shown below, Schedule 1). Samples were submitted to ALS Brasil Limitada's ("ALS") preparatory laboratory in Parauapebas, located approximately 72km from Luanga, and then sent to their laboratories in Peru and Vancouver for assaying (Schedule 2).
A comparison of the original historic intercepts with the Bravo twin hole intercepts is tabulated below. Bravo's twin hole intercepts closely correlate with the immediately adjacent historic drill holes in both thicknesses and grades, noting that Bravo nickel grades are for sulphide nickel, which is representative of potentially recoverable nickel (by conventional flotation treatment), and does not include non-recoverable silicate nickel.

Schedule 2: Assay Methodologies and QAQC
Drill core sampling followed a chain of custody between collection, processing and delivery to the ALS laboratory in Parauapebas, state of Para?, Brazil. The drill core was delivered to the core shack at Bravo's Luanga site facilities and processed by geologists who inserted certified reference materials, blanks and duplicates into the sampling sequence. The NQ drill core was quarter cut and placed in secured polyurethane bags, then in security-sealed sacks before being delivered directly from the Luanga site facilities to the Parauapebas ALS laboratory by Bravo staff. If the ALS rhodium overlimit of >1.00g/t rhodium is reached Bravo will send the pulps to SGS re-analysis. Samples were prepared and analyzed following procedures summarized in the table below and additional information about the methodology can be found on the respective ALS or SGS global websites (ALS, SGS) in their analytical guides. Information regarding preparation and analysis of historic drill core is also presented in this table where the information is known.
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.
