Cabral Gold Reports High-Grade Results in 2 Separate Targets at the Cuiú Cuiú Gold District, Brazil

Cabral Gold hits 52.3 g/t gold at Machichie Main and 49m @ 2.0 g/t at Jerimum Cima, expanding oxide resource potential in Brazil's Cuiú Cuiú district.
- Cabral Gold reported exceptional drilling results from two key targets, with drill hole RC0499A returning 2m @ 52.3 g/t gold at Machichie Main and RC0561 intersecting 49m @ 2.0 g/t gold at Jerimum Cima.
- The Machichie Main discovery represents a previously unrecognized high-grade zone located in the western part of the deposit, with mineralization occurring in highly altered intrusive rock at 41m depth.
- Jerimum Cima results confirm the presence of a fifth gold-in-oxide blanket within the Cuiú Cuiú district, potentially extending mine life and increasing production for the Phase 1 starter operation.
- Multiple additional intercepts were reported across both targets, including significant near-surface mineralization in blanket sediments and saprolite material suitable for oxide processing.
- Both discoveries remain open in multiple directions and at depth, suggesting potential for resource expansion through continued drilling programs.
Cabral Gold Inc. is a junior resource company focused on the identification, exploration, and development of gold properties in Brazil. The company holds a 100% interest in the Cuiú Cuiú gold district located in the Tapajós Region within Pará state in northern Brazil. The project currently contains National Instrument 43-101 compliant Indicated resources of 12.29Mt @ 1.14 g/t gold (450,200oz) in fresh basement material and 11.11Mt @ 0.48 g/t gold (171,883oz) in oxide material, plus Inferred resources of around 606,708 gold ounces in fresh basement and oxide materials.
Machichie Main High-Grade Discovery
The latest drilling results from Machichie Main have revealed a significant new zone of high-grade mineralization. Drill hole RC0499A delivered the standout result of 2m @ 52.3 g/t gold from 41m depth within highly altered intrusive rock in the western part of the deposit. This represents a previously unrecognized zone of high-grade gold mineralization that occurs between known mineralized zones.
Additional strong results from the program included drill hole RC0529, which intersected multiple mineralized intervals including 9m @ 0.72 g/t gold from 28m depth and 25m @ 0.93 g/t gold from 43m depth. The program also returned several notable intercepts in near-surface oxide material, including 18m @ 0.87 g/t gold from surface in blanket sediments and 8m @ 1.26 g/t gold from 13m depth in saprolite.
According to President and CEO Alan Carter, "These latest drill results from the Machichie Main gold deposit indicate the presence of a new previously unrecognised high-grade zone immediately south of the main gold deposit. These results come on top of recent very high-grade results at the nearby Machichie NE target located 150m to the northeast of Machichie Main."
Strategic Importance of Oxide Material
The presence of excellent gold values in near-surface blanket sedimentary material and saprolite holds particular significance for Cabral's development plans. Carter noted that these results "augers well for the expansion of the current gold-in-oxide blanket at Machichie Main and its potential inclusion in revised resource and reserve estimates which are expected in the next few weeks as part of the updated PFS on the gold-in-oxide starter operation."
Brian Arkell, Cabral's VP of Exploration and Technical Services, emphasized the discovery's importance in the company news release:
"Machichie is a very significant discovery in that it potentially provides a higher-grade source of feed for the proposed oxide heap leach process plant. We've hit several higher-grade zones of near-surface mineralization along the 900-metre strike length and our drilling, while still widely spaced, is showing good continuity."
The Machichie Main zone trends east-west and is located 500 metres north of the MG gold deposit. The zone features primary mineralization within intrusive rocks overlain by an extensive weathered layer consisting of near-surface sediments and underlying saprolite, both considered gold-in-oxide material. A preliminary Inferred resource estimate of 3.73 million tonnes @ 0.5 g/t gold was previously calculated for the gold-in-oxide material at Machichie Main.
Jerimum Cima Emerges as Fifth Oxide Target
The drilling program at Jerimum Cima has confirmed the presence of another significant gold-in-oxide blanket within the district. The standout result came from drill hole RC0561, which intersected 49m @ 2.0 g/t gold from 7m depth in saprolite, including high-grade intervals of 1m @ 8.1 g/t gold from 7m depth, 1m @ 57.0 g/t gold from 21m depth, and 1m @ 7.1 g/t gold from 35m depth.
The target is located 3km ENE of the Central gold deposit and 3.5km NW of the MG gold deposit. It is characterized by a strong gold-in-soil anomaly of +100ppb gold covering an area of 900m x 1000m, comparable to the anomalies above the established MG and Central gold deposits.
Previous reconnaissance drilling at Jerimum Cima had returned 39m @ 5.1 g/t gold in primary intrusive rock material, while surface trenching yielded multiple significant intercepts including 18m @ 1.9 g/t gold, 14m @ 1.6 g/t gold, 20m @ 1.2 g/t gold, 10m @ 1.3 g/t gold, and 24m @ 0.7 g/t gold in weathered gold-in-oxide blanket and saprolite material.

Resource Expansion Potential
Carter highlighted the dual significance of the Jerimum Cima results:
"The excellent near-surface gold grades returned from RC561 are thus important for two reasons. Firstly, they auger well for the potential to add to the current gold-in-oxide resource base within the project area and possibly extend the mine life and/or increase annual production of the Phase 1 starter operation. Secondly and perhaps more importantly, these results together with previous drilling and trench results suggest the presence of an underlying primary zone of gold mineralization in intrusive rocks below the weathered gold-in-oxide cap."
The mineralized zone at Jerimum Cima appears to trend east-west over at least 400m and remains open to the east and west and at depth. Recent results suggest this zone may be the same as that intersected in previous drilling and trenching, indicating continuity across the target area.
Future Investment Outlook
The Cuiú Cuiú project is located within the Tapajós Gold Province, which historically produced an estimated 30 to 50 million ounces of placer gold between 1978 and 1995, representing Brazil's largest gold rush. Cuiú Cuiú was the largest area of placer gold workings in the Tapajós region and produced an estimated 2 million ounces of placer gold historically.
Both discovery areas remain open in multiple directions, with additional drilling planned to determine the extent of mineralization. The company currently has results pending on 35 RC drill holes and plans to increase the number of drill rigs on site in the coming weeks. For investors evaluating Cabral Gold, these latest results demonstrate the company's ability to continue expanding its resource base through systematic exploration within an established gold district. The discovery of high-grade zones at both Machichie Main and the confirmation of a fifth oxide blanket at Jerimum Cima suggest significant potential for resource growth.
The focus on oxide material is particularly strategic given the company's planned heap-leach starter operation, which could provide earlier cash flow generation compared to processing primary ore. However, investors should note that while these results are encouraging, the discoveries require additional drilling to define their full extent and economic potential. The company's position within a historically prolific gold region provides geological confidence, but successful development will depend on continued exploration success and efficient project execution.
