Cabral Gold Drills New Mineralized Structure Connecting PDM and Central Gold Deposits, Cuiú Cuiú Gold District, Brazil

Vancouver, British Columbia--(Newsfile Corp. - December 4, 2025) - Cabral Gold Inc. (TSXV: CBR) (OTCQB: CBGZF) ("Cabral" or the "Company") is pleased to announce drill results from 17 shallow reconnaissance RC drill holes at the previously untested Mutum target located 1300 metres NW of the Central Gold deposit and 500 metres ("m") SE of the PDM gold discovery within the Cuiú Cuiú district.

Highlights

• The Company has identified a new and previously unrecognized mineralized structure which appears to extend for 1.8 kilometres ("km") in a NW-SE direction and connects the Central gold deposit with the PDM gold discovery further to the north

• Reconnaissance drill intercepts from the Mutum target, which is located 1.3km NW of the Central gold deposit and 500m SE of the PDM gold discovery, include 8m @ 1.32 grams per tonne ("g/t") gold from 43m depth in RC0602, 13m @ 0.83 g/t gold from 11m depth in RC0604, and multiple mineralized intervals including 4m @ 0.76 g/t gold from 29m depth and 4m @ 1.06 g/t gold from 41m depth in RC0603

• The mineralized structure at Mutum was identified on the basis of a recent airborne drone magnetic survey over the area followed by follow up reconnaissance drilling. This survey revealed a clear NW-trending structural corridor that was not visible in earlier airborne data

• The Company has subsequently purchased its own in-house drone magnetic system and intends to fly the entire Cuiú Cuiú district as quickly as possible in advance of additional reconnaissance drilling, particularly along the new NW trending structure linking PDM with Central

Alan Carter, Cabral's President and CEO commented, "The significance of the results from several of the shallow reconnaissance drill holes recently completed at the previously untested Mutum target at Cuiú Cuiú cannot be overstated. These drill results are from a previously untested area located 1.3km NW of the Central gold deposit and 500m SE of the PDM gold discovery, and indicate that a NW-trending mineralized structure extending for 1.8km connects the two deposits. This opens up a very large area of prospective ground between Central and PDM for follow up drilling.

The drone magnetic test survey that we recently completed has generated a lot of high-resolution magnetic data that are much more effective at mapping mineralized structures than the existing fixed wing airborne data. This will generate important advances in our understanding of the structural controls on gold mineralization at other deposits and targets within the Cuiú Cuiú district."

Mutum RC Drill Results

The Mutum target is located approximately 500 to 700m south-east of the PDM gold discovery and 1.3km north-west of the Central gold deposit within the Cuiú Cuiú gold district. (Figure 1). Mutum, PDM and Central are all located within a north-west trending corridor defined by anomalous gold-in-soil and auger sampling.

Previous surface trenching on the eastern side of the Mutum target returned 32m @ 1.0g/t gold, 25m @ 0.9g/t gold and 16.5m @ 0.9g/t gold. In addition, several isolated gold-in-auger anomalies occurred to the south-west of the main Mutum target and include TR031 which returned 3m @ 0.31 g/t gold from 3m depth and TR079 which returned 4m @ 0.89 g/t gold from 6.8m depth.

The Mutum target area is characterised by thick soil cover associated with a valley and low gold-in-soil values. Thus far it has not been a high priority for follow up and has never been previously drill-tested. The regional airborne magnetic data also revealed no obvious targets in this area.

However, recent drilling at the PDM target located 500m NW of Mutum, including drill results of 23m @ 4.7 g/t gold (See press releases dated September 25, 2025 and October 22, 2025), and the recognition that PDM is very likely a significant gold deposit in its own right, has led to a re-examination of the area between PDM and Central. Specifically, the Company conducted a drone magnetic test survey at Mutum with the objective of acquiring higher resolution magnetic data by flying significantly closer to the ground than the previous fixed wing airborne magnetic survey, which was flown at a constant height. The objective of the test survey was to determine whether it would be possible to map geological structures with the drone magnetic system.

The results from the drone magnetic survey were striking and significantly exceeded our expectations. The test survey clearly shows a NW trending structure controlling the Central gold deposit extending NW for at least 1.8km and connecting with the PDM gold discovery to the north-west (Figure 2). Whilst this structure was not coincident with the area of anomalous gold values in trenching 300m to the north-east, the structure is coincident with isolated gold-in-auger anomalies.

A total of 17 reconnaissance RC holes were completed in the Mutum area. Of these, 12 holes (RC0590 to RC0601) were drilled in the area of the anomalous trenches described above and returned only narrow zones of low grade gold mineralization including 3m @ 2.80 g/t gold in RC0591, 2m @ 1.43 g/t gold in RC594, and 6m @ 0.56 g/t gold and 3m @ 0.63 g/t gold in RC0595 (Figure 2, Table 1).

Note increased resolution within area of test survey and NW trending magnetic low anomaly in blue indicative of a structure linking the Central gold deposit with the PDM discovery 1.8km to the north-west. The location of drill holes RC0602, RC0603 and RC0604, which all cut gold, is also highlighted.

However, three shallow reconnaissance holes, RC0602, RC0603 and RC0604 that were drilled 300m to the south-west on top of the structure evident from the drone magnetic survey and at the location of a gold in auger anomaly all cut significant intervals of gold mineralization in saprolite. Specifically, RC0602 returned 8m @ 1.32 g/t gold from 43m depth, RC0604 returned 13m @ 0.83 g/t gold from 11m depth, and RC0603 returned multiple low-grade intervals including 4m @ 0.76 g/t gold from 29m depth and 4m @ 1.06 g/t gold from 41m depth (Figures 3 and 4, Table 1).

It is important to note that this area has never been previously drill tested and these reconnaissance drill results are from a recently identified structure which appears to directly connect the Central gold deposit and the PDM discovery within the Cuiú Cuiú district. The nearest hole at PDM is 500m to the north-west and the nearest hole at Central is 1.5km to the south-east. Consequently, these results open up the possibility that the intervening 1.8km strike length between Central and PDM could be mineralized.

In light of these results, the Company is planning a campaign of follow up RC drill holes along a series of east-west traverses drilled perpendicular across the recently identified lineament which extends NW-SE for 1.8km and appears to connect the Central gold deposit to the PDM discovery.

The Company has also purchased its own in-house drone magnetic system, which is now on site, and intends to fly the entire Cuiú Cuiú district as quickly as possible. The exploration team believes that based on the results from the Mutum area, drone-based magnetics have the potential to provide important new insights into the structural controls on gold mineralization within the Cuiú Cuiú district.

Drill results are pending on one additional diamond drill hole at Machichie NE as well as nine diamond drill holes at the Machichie Main area, and five diamond drill holes at the Jerimum Cima target. Diamond drilling with 2 rigs is currently in progress at the Jerimum Cima target aimed at defining the limits of the mineralized zones identified to date and establishing a maiden resource estimate, and at the MG gold deposit where drilling is aimed at expanding the gold deposit down dip. RC drilling with 1 rig is also currently in progress at the Moreira Gomes gold deposit.
