GoldHaven Advances Copeçal Toward Q3 Drilling; Identifies Priority Eastern Targets
VANCOUVER, June 04, 2026 - GoldHaven Resources Corp. ("GoldHaven" or the "Company") is pleased to provide an update on preparations for a planned Phase II drill program at its 100%-owned Copeçal Gold-Copper Project in Brazil. Subject to the successful completion of the Company's ongoing LIFE financing, GoldHaven intends to advance drill planning and target refinement with the objective of commencing a follow-up drill campaign during Q3 2026.
Highlights:
- GoldHaven targeting commencement of Phase II drilling at Copeçal during Q3 2026
- Independent geological review identifies eastern extension of East Target as a priority drill target
- Follow-up drilling planned to test mineralization along strike and at depth from hole COP-009
- Ongoing geological interpretation supports an copper-gold exploration model
- Recently announced LIFE Offering expected to provide flexibility for expanded exploration activities
Following completion of an independent review and ongoing GIS modelling work, GoldHaven has refined its understanding of the Copeçal mineralizing system and is advancing preparations for a follow-up drill campaign targeted for Q3 2026.
The Company's ongoing interpretation supports the presence of a large hydrothermal system and has identified the eastern extension of the East Target as a priority area for future drilling. This target area remains largely untested by diamond drilling and is considered prospective for evaluating the continuity and scale of alteration and sulphide mineralization identified during the initial drill campaign.
"With our LIFE financing nearing completion, we are turning our attention toward the next phase of exploration at Copeçal," stated Rob Birmingham, CEO of GoldHaven. "The work completed to date has strengthened our understanding of the hydrothermal system and identified the eastern extension of the East Target as a priority drill area. We believe the upcoming Q3 program will be an important step in determining whether the alteration, structural controls and copper-bearing sulphides identified to date represent the peripheral expression of a larger copper-gold system."
Recent work has focused on the significance of localized bornite and chalcopyrite mineralization encountered within hydrothermal breccia and alteration zones at the East Target. While the mineralization intersected to date remains limited in extent and grade, management believes the occurrence is significant because it demonstrates the presence of copper-bearing fluids within the system and provides an important vector for future exploration.
GoldHaven cautions that the presence of alteration and copper-bearing sulphide minerals does not necessarily indicate the existence of an economically recoverable mineral resource. Additional drilling and technical evaluation will be required to determine the significance and extent of the mineralization encountered to date.

The Company continues to advance Copeçal through a multi-disciplinary exploration approach that integrates modern geological interpretation with historical datasets generated by prior operators, including AngloGold Ashanti. This approach combines historical drilling, geochemical and geophysical information with recent field mapping, soil sampling, and diamond drilling results to enhance targeting and improve vectoring toward potentially mineralized centres.
The second phase drilling program is currently planned to commence during the third quarter of 2026, subject to final logistical planning and contractor availability.
The Company expects to finalize Phase II drill targeting in the coming months and will provide updates regarding mobilization, financing milestones, and exploration activities as they become available.
About the Copeçal Gold Project: A Brief History
The Copeçal Gold Project is strategically situated within the Alta Floresta Gold Province, a historically productive region that has yielded substantial gold discoveries since the late 1970s. GoldHaven' s tenements cover a total of 3,681 hectares in a geologically favourable setting within the Juruena Gold Province of Brazil.

The Juruena Gold Province, also known as the Juruena Magmatic Arc, is an orogenic belt highly prospective for mesothermal shear-related and intrusion-related gold deposits, such as G-Mining's Tocantinzinho deposit. Additionally, the region hosts recently identified porphyry-style deposits (e.g., Serabi, Jaca) and epithermal-style deposits (e.g., X1, Aura). The presence of multiple deposit styles, along with the confirmation of large-scale gold deposits in the Juruena Province of Brazilzil, underscores the significant potential of the Copeçal Gold Project.
Recent exploration programs, including geochemical soil sampling, drone-mounted magnetometry surveys, and historical drilling data, indicate the presence of multiple gold-bearing structures. Notably, AngloGold Ashanti previously conducted systematic exploration on the property from 2010 to 2016, including auger and air-core drilling, geophysical surveys, and rock geochemistry, identifying multiple zones of anomalous gold mineralization.
The Copeçal Gold Project benefits from extensive historical work, with AngloGold Ashanti's exploration confirming gold and arsenic anomalies, indicative of significant mineralization potential. Soil sampling grids and follow-up auger drilling in key areas revealed consistent gold values over wide zones, further supporting the presence of a substantial mineralized system.
