GoldHaven Awards Contract for Eight-Hole, 1,650-Metre Phase II Drill Program at Copeçal West Target, Brazil

Phase II drill program to test the strike and depth extent of a fold-controlled gold system within the western portion of the 6-kilometre gold-in-soil anomaly

VANCOUVER, British Columbia, Aug. 06, 2026 (GLOBE NEWSWIRE) -- GoldHaven Resources Corp. ("GoldHaven" or the "Company") (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to announce that it has contracted Layne do Brasil Ltda. to complete a second phase of diamond drilling at the West Target of its 100%-owned Copeçal Gold Project in Mato Grosso State, Brazil.

Layne do Brasil Ltda. is an established Brazilian drilling contractor with extensive experience supporting exploration and mine development projects throughout the country.

Highlights

• Up to eight diamond drill holes, totalling 1,650 metres, are planned at the Copeçal West Target.
• Drilling will follow up previously reported bedrock gold intercepts associated with sheeted quartz veining and related geochemical and structural targets.
• Targets were generated through the integration of historical and recent soil and auger geochemistry, diamond drilling, geological and structural interpretation, magnetic data and VLF geophysics.
• Mobilization is expected to commence by mid-August 2026, with completion of the drilling program targeted before year-end.
• The program will test interpreted target horizons along strike, down dip and down plunge, including fold limbs, hinge-related targets and areas where multiple exploration datasets converge.
  
  

The Phase II program builds on GoldHaven’s inaugural diamond drilling campaign, which confirmed bedrock gold mineralization in all four holes drilled at the West Target. Reported intervals included 30 metres at 0.16 g/t Au, 28 metres at 0.14 g/t Au (including 4 metres at 0.48 g/t Au) and 39 metres at 0.11 g/t Au (including 4 metres at 0.30 g/t Au). Previous work identified sheeted quartz veining, folding, shearing and hydrothermal alteration interpreted to form part of a structurally controlled mineralizing system.

Gold in fold-hosted systems commonly concentrates within fold hinges and closures. Phase II is designed to test whether the interpreted fold at the West Target hosts a continuous mineralized zone along strike and down plunge.

The Copeçal Project lies within the Juruena Gold Province, approximately 150 kilometres from G Mining Ventures’ Tocantinzinho gold mine. The Phase II program tests a portion of a 6-kilometre gold-in-soil anomaly defined by AngloGold Ashanti’s systematic exploration between 2010 and 2016, the majority of which remains untested by drilling.

The East Target, where copper-gold sulphide zonation (bornite–chalcopyrite) has been identified, remains a priority for future phases of work.

The proposed holes are designed to evaluate the lateral, down-dip and down-plunge continuity of the target horizons while testing key components of the Company’s evolving geological and structural model. These include interpreted fold closures, the geometry of the northern and southern limbs, extensions of gold-bearing intervals identified in previous diamond and historical auger drilling, and priority structural trends interpreted from magnetic and VLF datasets.

Rob Birmingham, Chief Executive Officer of GoldHaven, commented:

“Copeçal has earned this next phase of drilling. Our inaugural program confirmed bedrock gold in all four West Target holes, together with sheeted quartz veining, fold-controlled enrichment and hydrothermal alteration across the system confirming a coherent mineralized system with encouraging geological continuity.”

“What we have not yet tested is the core of it. Phase II is designed to follow the fold geometry down-plunge and along strike into the portions of the system that no drill has reached. We have eight holes planned and a clear geological model to test. I believe the results will tell us whether this system has the continuity and grade to become something meaningful.”

The planned holes are designed to systematically test the highest-priority structural targets while improving the Company's understanding of the geometry of the mineralized system.

Phase II Drill Program

• PROG-1: tests plunge extension.
• PROG-2 to PROG-4: test southern limb continuity.
• PROG-5 to PROG-7: define fold geometry.
• PROG-8: tests a new down-dip target.
  
  

The current conceptual design comprises eight holes (PROG-1 through PROG-8) totalling up to 1,650 metres. Final collar locations, hole depths, orientations, sequencing and total meterage may be modified as drilling progresses based on geological observations, initial results and operational considerations.
