Cabral Gold Inc. (TSX-V: CBR) (OTCQX: CBGZF)  is pleased to announce results from 38 additional reverse circulation infill drill holes recently drilled as part of the pre-production drill-to-measured resource upgrade and production de-risking of the gold-in-oxide ore within the MG starter pit at the Cuiú Cuiú Gold District, Brazil.

Highlights

• The stand-out hole from this batch of results was RC737 which returned 25m @ 7.47 g/t gold from surface including 10m @ 17.09 g/t gold from 6m depth. This interval included a higher-grade section of 2m @ 69.3 g/t gold

• This intercept, at 185 gram*meters ranks as #14 on the drill intercept grade-thickness scale of all holes drilled within the Cuiú Cuiú district to date and comes just a week after DDH384 at Jerimum Cima which returned 107.6m @ 2.5 g/t gold including 17.8m @ 13.0 g/t gold, ranking #5 at 269 gram*meters (see press release dated June 2, 2026)

• Drilling has been completed at MG on this program for a total of 5,767 meters drilled in 166 holes. Assay results have been released on 124 holes and are pending on the final 42 infill holes

Alan Carter, Cabral’s President and CEO commented, “These additional infill drill results at MG continue to confirm the presence of consistent, higher gold-in-oxide grades over significant widths, from surface, providing us with greater confidence in planned ore delivery during the initial years of mining at MG. The results from RC737 mean that it is one of the best holes ever drilled within the MG gold deposit, and also within the wider Cuiú Cuiú district. The higher grades noted in several holes at MG, including RC737, could reflect zones of higher-grade mineralization within the underlying primary gold deposit at MG”.

MG RC Infill Drill Results

The MG gold deposit is one of the two main gold deposits that currently comprise the Indicated and Inferred resource base at Cuiú Cuiú (see Figure 1). As with the nearby Central gold deposit, the upper portion of the subvertical MG gold mineralization is extensively weathered resulting in a vertical profile of saprolite extending to 60 meters  depth. This saprolite together with the overlying blanket sediments and soils, which are also mineralized, will form the starter pit for the Phase 1 gold-in-oxide mining operation which is due to commence production in Q4 2026.

The objective of the RC infill drill program at MG is to provide greater confidence in the grade and continuity of the planned oxide-gold ore supply from MG to the heap leach pad, ahead of mining, and to further refine the mine plan that was developed as part of the PFS study release in July 2025 (see press release dated July 29, 2026).

Results have been received on an additional 38 infill RC holes, each drilled to 25m depth, targeting the gold-in-oxide material in the eastern and central parts of the MG starter pit. These follow the receipt of results previously from 86 infill RC holes (see press releases dated April 7, May 7, and May 25, 2026). The program of infill drilling was designed to enhance the level of confidence around the Year 1 mine plan at MG and to upgrade the current resource by the end of this month. The infill drilling program at MG has completed a total of 166 RC holes totalling 5,767m.

The RC drill results reported to date confirm the presence of good grades, from surface, within the weathered saprolite and overlying sedimentary blanket and the Year 1 pit outline (see Figure 2, Table 1).

Of particular note, are the following RC drill results;

• 24m @ 0.79 g/t gold from surface in RC714
• 19m @ 2.19 g/t gold from surface including 7m @ 5.05 g/t gold in RC715
• 25m @ 1.65 g/t gold from surface including 2m @ 8.57 g/t gold in RC716
• 25m @ 0.87 g/t gold from surface in RC717
• 25m @ 0.61 g/t gold from surface in RC718
• 25m @ 0.65 g/t gold from surface in RC719
• 24m @ 0.69 g/t gold from surface in RC722
• 25m @ 1.89 g/t gold from surface including 8m @ 4.52 g/t gold in RC723
• 20m @ 0.93 g/t gold from surface in RC724
• 20m @ 2.59 g/t gold from surface including 6m @ 7.08 g/t gold in RC725
• 25m @ 0.84 g/t gold from surface in RC729
• 25m @ 1.14 g/t gold from surface in RC730
• 18m @ 1.99 g/t gold from surface in RC732
• 25m @ 1.28 g/t gold from surface in RC733
• 25m @ 0.84 g/t gold from surface in RC736
• 25m @ 7.47 g/t gold from surface including 10m @ 17.09 g/t gold in RC737
• 16m @ 1.63 g/t gold from surface in RC738
• 19m @ 0.85 g/t gold from surface in RC741
• 25m @ 0.72 g/t gold from surface in RC742
• 23m @ 0.76 g/t gold from surface in RC743

All of the holes reported herein were drilled within the Year 1 pit to a maximum depth of 25m (Figure 2, Table 1). Many of the holes ended in mineralization. Figures 3 and 4 show cross-sections for holes drilled in the central part of the gold-in-oxide deposit and results for;

1. holes RC731, RC735, and RC737 (which returned 25m @ 7.47 g/t gold from surface including 10m @ 17.09 g/t gold from 6m depth, which included a higher-grade section of 2m @ 69.3 g/t gold) (Figure 3), and

1. holes RC732 (which returned 18m @ 1.99 g/t gold from surface), RC733 (which returned 25m @ 1.28 g/t gold from surface), RC734, RC736 (which returned 25m @ 0.84 g/t gold from surface) and RC738 (which returned 16m @ 1.63 g/t gold from surface) (Figure 4)

These results are in line with the existing MG mine plan and confirm the pre-existing drill hole results and validate the geological model demonstrating the presence of significant near surface resources with good grade material amenable to heap leach.

The Tapajós Gold Province is the site of the largest gold rush in Brazil’s history which according to the ANM (Agência Nacional de Mineração or National Mining Agency of Brazil) produced an estimated 30 to 50 million ounces of placer gold between 1978 and 1995. Cuiú Cuiú was the largest area of placer workings in the Tapajós and produced an estimated 2Moz of placer gold historically.
