Jerimum Cima Is Emerging as a New High-Grade Center at Cuiú Cuiú

• Cabral Gold reported a drill intercept of 107.6 meters at 2.5 g/t gold at Jerimum Cima, including a high-grade core of 17.8 meters at 13.0 g/t gold.
• Jerimum Cima is not part of Cabral's existing gold resource, meaning successful resource definition there would add directly to the company's total gold inventory.
• The high-grade zone has now been traced continuously for at least 455 meters along strike & remains open in both directions & at depth.
• Cabral is running 3 drill rigs at Jerimum Cima with the goal of generating an initial resource estimate for the target.
• The company is targeting the start of commercial gold production from its Phase 1 heap leach operation in the fourth quarter of 2026.

Cabral Gold (TSXV: CBR | OTCQB: CBGZF) announced on June 02, 2026, that its Jerimum Cima target has returned a standout drill result: 107.6 meters of rock averaging 2.5 grams per tonne (g/t) gold, with a high-grade core of 17.8 meters at 13.0 g/t gold, including a 3.8-meter section running at nearly 60 g/t gold. Jerimum Cima is not yet part of Cabral's existing gold resource, meaning any future resource definition there would add to what the company already has.

What the Drilling Found

The best hole from this batch, DDH384, was drilled into the central-eastern part of the Jerimum Cima target to test how far the high-grade zone extends along strike & how deep it goes. The results suggest it runs continuously for at least 455 meters along strike & reaches at least 60 meters deeper than previously known, & both directions remain open for further expansion.

Earlier holes at Jerimum Cima had already returned high grades, including 9.5 meters at 87.4 g/t gold & 45.6 meters at 4.5 g/t gold. The company believes DDH384 intersected the same mineralized zone as those earlier holes, pointing to a connected, continuous body of gold-bearing rock rather than isolated pockets.

2 other holes reported at the same time, DDH375 & DDH382, returned lower grades. The difference between those results & DDH384 reflects how gold is often concentrated along specific structural features underground, rather than being evenly spread.

What Management Is Saying

Alan Carter, President & CEO of Cabral, was direct about the significance of what is being found:

"The Jerimum Cima target continues to deliver extraordinary drill results & 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."

Carter identified the 2 key takeaways from the latest hole: it adds further evidence that the high-grade zone is continuous along strike, & it shows the zone extends deeper than the company had previously been able to confirm.

Brian Arkell, Vice President (VP) of Exploration at Cabral, noted that the mineralized structure at Jerimum Cima remains open to the east for up to 2 kilometers, suggesting significant room for further discovery beyond the area drilled so far.

Where Jerimum Cima Fits in the District

Cuiú Cuiú is a large gold district in Brazil's Tapajós Region, a province with a well-documented history of gold production. The ANM (Agência Nacional de Mineração), Brazil's national mining regulator, estimates the region produced between 30 & 50 million ounces of placer gold between 1978 & 1995. Cuiú Cuiú itself accounted for an estimated 2 million ounces of that historical output.

Jerimum Cima sits between 2 of Cabral's existing gold deposits, the Central deposit to its west & the MG deposit to its southeast. The target shares the same type of geological structure that hosts gold at both of those deposits, which gives the company reason to treat it as a potentially meaningful discovery rather than an isolated anomaly.

The Bigger Picture for Investors

Cabral's existing gold resource at Cuiú Cuiú, spread across 3 deposits, already contains a substantial inventory of gold in both oxide (near-surface) & fresh basement rock. The company is currently building a Phase 1 heap leach operation to process the near-surface oxide material & is targeting the start of commercial gold production in the fourth quarter of 2026.

Jerimum Cima sits entirely outside that existing resource count. The company's stated goal for current drilling is to generate an initial resource estimate for the target, a process that, if successful, would add a new line item to Cabral's overall gold inventory.

With 3 drill rigs active at Jerimum Cima & results still pending, the picture of how large the target could become is still forming. Drilling is also running in parallel at several other targets across the district, with the company aiming to update its total resource base later this year.
