GoldHaven Resources Mobilizes Drill Contractor to Copeçal Gold Project, Mato Grosso, Brazil

Maiden Diamond Drill Program to Test High-Priority Gold Targets

VANCOUVER, British Columbia, Sept. 24, 2025 (GLOBE NEWSWIRE) -- GoldHaven Resources Corp. (CSE: GOH | OTCQB: GHVNF) (“GoldHaven” or the “Company”) is pleased to announce that the drill contractor has mobilized to site to commence the Company’s maiden diamond drilling program (see previous press release dated 09/09/2025) at the Copeçal Gold Project in Mato Grosso State, Brazil.

This marks a major milestone for GoldHaven as it transitions from early-stage exploration to targeted drilling on high-priority gold anomalies, following months of systematic groundwork.

Investment Highlights:

• Drill-Ready Project in a Tier-1 Jurisdiction
  Copeçal is located in the Juruena Gold Belt, one of Brazil’s most prospective but underexplored regions. The project comprises 3,681 hectares, 100% owned by GoldHaven, and includes ground previously explored by AngloGold Ashanti.

• Compelling Targets Defined
  Two large-scale soil anomalies (“East” and “West”), each with 3 km strike lengths, have been delineated. These anomalies align with a major regional scale shear zone, often a hallmark of the orogenic gold systems targeted by the company.
  Auger drilling (107 holes), a VLF-EM geophysical survey and historical data generated by prior exploration phases (Boa Gold, AngloGold Ashanti) have confirmed structural controls and helped pinpoint diamond drill locations.

• Strong Technical Rationale
  The drill program aims to intersect primary bedrock with the targeted gold mineralization beneath the strongest geochemical anomalies. Results from the auger program and ongoing geophysics have significantly de-risked this phase.
  
  

“This is a key value-creation moment for GoldHaven,” stated Rob Birmingham, CEO. “We’ve built a strong technical foundation and are now able to drill-test our priority targets associated with consistent gold-in-soil anomalies linked to robust geological structures defined by our geophysical programs. With drilling almost underway, we are entering a phase of potentially significant discovery upside.”

Copeçal Gold Project Drill Targets:

GoldHaven has identified two high-priority drill targets, East and West, for its upcoming diamond drilling program. The program will consist of a total of 1200m of diamond drilling with 5-6 angled NQ holes up to 150m deep at both targets.
