Cabral Gold Drills Widest High-Grade Intercept Yet at Jerimum Cima, Extending Mineralised Zone Beyond Previous Depth Limits

• Hole DDH384 at the Jerimum Cima target returned the widest high-grade intercept yet recorded at the discovery, with results entirely in primary mineralisation.
• The high-grade zone intersected in DDH384 is interpreted to be continuous with zones hit in previous holes, confirming the system has now been traced along 455 metres of strike and extends deeper than previously established.
• Jerimum Cima is not included in Cabral Gold's existing National Instrument 43-101 (NI 43-101) resource base, meaning any future resource estimate at the target would be additive to the current project inventory.
• The target carries a gold-in-soil anomaly comparable in scale to those above the company's existing MG and Central deposits, and is controlled by the same fault structure that hosts other discoveries in the district.
• Drilling continues at Jerimum Cima with two diamond rigs and one reverse circulation (RC) machine, with the objective of generating an initial resource estimate for both the oxide blanket and underlying primary zones.

Company Overview

Cabral Gold (TSXV: CBR, OTCQB: CBGZF) is a junior resource company engaged in the exploration, development, and near-term production of gold properties in Brazil. The company holds a 100% interest in the Cuiú Cuiú gold district in the Tapajós Region of Pará state, northern Brazil. The district was the largest area of placer workings in the Tapajós Gold Province, which the Agência Nacional de Mineração (ANM) estimates produced between 30 and 50 million ounces of placer gold between 1978 and 1995; Cuiú Cuiú alone is estimated to have produced 2 million ounces historically.

Three main gold deposits have been defined at the Cuiú Cuiú project, carrying NI 43-101 compliant Indicated and Inferred resources across both fresh basement and oxide material. The primary resource is based on an NI 43-101 technical report dated October 2022, while oxide resources are based on technical reports dated October 2024 and July 2025 respectively. Jerimum Cima is not included in any of these estimates. The company is currently constructing a Phase 1 gold-in-oxide heap leach operation based on a Preliminary Feasibility Study (PFS) dated July 2025 and is targeting commercial gold production in the fourth quarter of 2026.

DDH384 Returns Widest Intercept on Record at Jerimum Cima

Cabral Gold released results on 2 June 2026 from three additional diamond drill holes at the Jerimum Cima target within the Cuiú Cuiú Gold District. The headline result, hole DDH384, is the widest high-grade intercept yet reported at the target and establishes mineralisation at greater depth than any previous hole at the discovery.

DDH384 was designed to test the continuity and down-dip extension of high-grade mineralisation intersected in previous drilling. It returned 107.6 metres at 2.5 g/t gold from 162.7 metres depth, including 17.8 metres at 13.0 g/t gold, itself containing a 3.8-metre interval grading 59.9 g/t gold. All intercepts are in primary mineralisation. The two additional holes, DDH375 and DDH382, returned lower-grade results and did not return intervals of comparable significance to DDH384.

President & Chief Executive Officer (CEO) of Cabral Gold, Alan Carter, described the standing of Jerimum Cima within the broader district:

"The Jerimum Cima target continues to deliver extraordinary drill results and is not currently part of the existing resource base at Cuiú Cuiú. It is clearly a significant mineralized system with some of the highest grades we have ever encountered within the district."

Strike Continuity & Depth Extension Confirmed

The zone intersected in DDH384 is interpreted to be the same high-grade structure cut in several earlier holes across the target. The drill programme has now traced high-grade mineralisation along 455 metres of east-west strike, with DDH384 confirming the zone extends at least 60 metres further down dip than previously established. The zone remains open along strike, particularly to the east, and remains open at depth.

Previous holes across the target have returned a series of high-grade intercepts that, taken together, define the emerging scale of the system. These include 9.5 metres at 87.4 g/t gold in DDH372, 10.2 metres at 8.7 g/t gold in DDH378, and 45.6 metres at 4.5 g/t gold in hole CC26, all interpreted to lie along the same continuous mineralised structure now intersected by DDH384.

Geology & District Context

The Jerimum Cima target sits within the Cuiú Cuiú district and shares the same structural and geochemical characteristics as other known deposits and discoveries in the area. Gold mineralisation is centred on a major east-west trending fault zone interpreted as a splay off the regional-scale Tocantinzinho fault system, the same structural setting as the MG gold deposit and the Machichie Main discovery. The target's gold-in-soil anomaly is comparable in scale to those associated with the MG and Central deposits and the PDM and Machichie Main discoveries.

Several parallel mineralised zones in the underlying intrusive rocks have now been identified at Jerimum Cima, extending over at least 900 metres. Surface trenching has also confirmed the presence of gold in shallower oxide material across the target area, with multiple trench intercepts reported in November 2024.

VP of Exploration, Brian Arkell, described the current state of the discovery and the direction of ongoing drilling:

"Jerimum Cima is shaping up to be a very promising discovery with several zones of gold mineralization now identified over a 900-metre strike length, and it is still open to the east and at depth. The mineralized structure at Jerimum Cima is open to the east for up to 2km and our drilling is focused on stepping out in this direction."

Next Steps

Drilling at Jerimum Cima is continuing with two diamond rigs and one RC machine, with the primary focus on stepping out to the east and drilling deeper to determine the full extent of the high-grade zone. The objective of the current programme is to generate an initial resource estimate for both the oxide and primary mineralised zones at Jerimum Cima.

Diamond drilling is also continuing at the Mutum target and the Central gold deposit, with further drilling planned at Jerimum Baixo, Machichie Main, and Machichie NE, all aimed at updating Cuiú Cuiú's global resource base later in 2026. Construction of the Phase 1 gold-in-oxide heap leach operation continues in parallel, with commercial gold production targeted for the fourth quarter of 2026.
