Company Overview

Cabral Gold Inc. (TSXV: CBR | OTCQX: CBGZF | FRA: C3J) is a junior resource company engaged in exploration, development, and near-term production from gold properties in Brazil. The company holds a 100% interest in the Cuiú Cuiú gold district in the Tapajós Region within the state of Pará. The district contains National Instrument (NI) 43-101 compliant resources totalling 666,300 ounces in Indicated categories and 525,700 ounces in Inferred categories across oxide and primary material. The company is constructing a Phase 1 gold-in-oxide heap leach operation and targets commercial production in the Fourth Quarter of 2026. 

Jerimum Cima High-Grade Zone Extends to 455 Metres Strike, Remains Open East and at Depth

Drilling at the Jerimum Cima target returned 10.2 metres at 8.7 grams per tonne (g/t) gold from a depth of 99.5 metres, including 1.3 metres at 62.5 g/t gold from a depth of 108.4 metres, according to the May 13, 2026, press release. The hole was drilled on section 551266E with an azimuth of 0 degrees and a dip of 55 degrees within the central eastern part of the target. The mineralised zone intersected is interpreted to be the same zone intersected by previous drill holes to the west, based on structural continuity and grade characteristics.

The correlation of the latest drill hole with previous holes defines a high-grade zone extending at least 455 metres along strike. A drill hole located 125 metres west previously returned 82.6 metres at 0.98 g/t gold, including 9.5 metres at 5.74 g/t gold. A drill hole located 205 metres west returned 9.5 metres at 87.4 g/t gold from 173.8 metres depth, including 2.9 metres at 285.5 g/t gold, as reported in the March 12, 2026, press release. A drill hole located 235 metres west returned 45.6 metres at 4.5 g/t gold, including 1.5 metres at 117.26 g/t gold. A drill hole located 455 metres west returned 49 metres at 2.0 g/t gold, including one metre at 57.0 g/t gold. The high-grade zone remains open along strike to the east and at depth.

President and Chief Executive Officer of Cabral Gold, Alan Carter, stated the following regarding the Jerimum Cima results:

"We believe this to be the same high-grade mineralised zone which has now been traced for 455m along strike and remains open to the east. The broader E-W trending mineralised zone, however, is significantly larger and is up to 200m wide and extends at least E-W for 750m along strike. We look forward to additional results in the near term as our drill program ramps up."

Broader Mineralised System at Jerimum Cima Measures 200 Metres Wide Over 750 Metres Strike Length

The high-grade zone at Jerimum Cima appears to form the core of a larger mineralised system. The broader east-west trending mineralised envelope measures up to 200 metres wide and extends at least 750 metres along strike. Three parallel mineralised zones in the underlying intrusive rocks have been identified at Jerimum Cima extending over at least 750 metres east-west.

The Jerimum Cima target is characterised by a gold-in-soil anomaly of greater than 100 parts per billion gold covering an area of 900 metres by 1,000 metres, comparable to gold-in-soil anomalies above the MG and Central gold deposits. Gold mineralisation at Jerimum Cima is centred on a major east-west trending fault zone that forms a splay off the regional-scale Tocantinzinho fault system, similar to the structural setting at the MG gold deposit and Machichie Main discovery.

MG Infill Drilling Confirms Grade Continuity in Primary Basement Material

Four diamond drill holes at the MG gold deposit were completed to address gaps in the 2022 resource model. All four holes intersected the mineralised zone, with results including 10.3 metres at 1.45 g/t gold from 152.2 metres depth and 7.2 metres at 1.12 g/t gold from 270.4 metres depth. The MG gold deposit is one of two main gold deposits comprising the Indicated and Inferred resource base at Cuiú Cuiú. Current Indicated and Inferred resources within gold-in-oxide material at MG amount to 8.86 million tonnes at 0.48 g/t Indicated (135,900 ounces) and 3.14 million tonnes at 0.22 g/t Inferred (22,500 ounces), based on the NI 43-101 technical report dated October 21, 2024.

The upper portion of the deposit is extensively weathered with saprolite extending to 60 metres depth, which, together with overlying blanket sediments, will form the starter pit for the Phase 1 gold-in-oxide mining operation targeting production in the Fourth Quarter of 2026. Infill reverse circulation (RC) drilling at the MG gold-in-oxide deposit is continuing with the objective of upgrading the current Probable reserve base.

Next Steps: Resource Update Targeted for Late 2026

Drilling is ongoing at the Jerimum Cima target with 2 diamond drill rigs and 1 RC rig to generate initial resources for the gold-in-oxide blanket and underlying primary mineralised zones. Diamond drilling is also ongoing at Mutum and Central. Further drilling is planned at Machichie Main and Machichie NE with the objective of updating the global resource base later in 2026.
