GoldHaven commences IP survey at Three Guardsmen copper project

GoldHaven Commences Targeted IP Survey Following High-Grade Copper Discoveries at Three Guardsmen

VANCOUVER, British Columbia, July 07, 2026 (GLOBE NEWSWIRE) -- GoldHaven Resources Corp. (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) ("GoldHaven" or the "Company") is pleased to announce that it has engaged Scott Geophysics Ltd. to conduct a targeted induced polarization ("IP") survey at its 100%-owned Three Guardsmen Project in northwestern British Columbia.

The IP survey represents the next phase of exploration at Three Guardsmen following the Company's successful 2025 field program, which confirmed widespread high-grade copper mineralization and strengthened the geological model for a potential porphyry copper system at depth. The survey is expected to commence in July 2026 and will cover approximately three kilometres across priority target areas, with the results expected to inform future exploration programs, including potential drill targeting.

Building on High-Grade Copper Discoveries

The Company's 2025 exploration program collected 126 surface rock samples, including 25 samples grading greater than 1.0% copper, confirming widespread copper mineralization across the property. Highlights included:

• 15.85% Cu (Sample J647161)
• 12.75% Cu (Sample J647629)
• 12.65% Cu (Sample J647753)
• 9.92% Cu (Sample J647163)
• 7.19% Cu (Sample J647162)
• 6.78% Cu (Sample J647337)

Grab samples are selective in nature and may not be representative of the mineralization hosted on the property.

The exploration program confirmed high-grade copper mineralization hosted within epidote-magnetite skarns, with extensive malachite-stained mineralization traced over more than one kilometre of strike. Geological observations also suggest the mineralized corridor may extend approximately 2.6 kilometres between the Canadian Verdee and Mildred showings.

Importantly, GoldHaven also identified porphyritic intrusive textures, elevated molybdenum values and systematic geochemical zoning transitioning from copper-silver mineralization toward bismuth-tellurium-gold assemblages. The Company believes these geological characteristics may represent vectors toward an intrusive heat source capable of driving the observed skarn mineralization and potentially a larger porphyry copper system at depth.

Advancing Drill Targets

Scott Geophysics Ltd. will complete a time-domain induced polarization survey utilizing a pole-dipole array designed to identify chargeability and resistivity anomalies that may represent sulphide mineralization beneath the known surface occurrences. Survey data will be processed throughout the program, with final pseudosections, plan maps and digital datasets expected following completion. Optional inversion modelling may also be completed to further refine priority drill targets.

When integrated with the Company's geological mapping, geochemistry and structural interpretation, the IP survey is expected to significantly improve GoldHaven's understanding of the geometry and continuity of the mineralized system while prioritizing areas for future drilling.

Rob Birmingham, Chief Executive Officer of GoldHaven, commented:

"Three Guardsmen continues to exceed our expectations. Last season's exploration confirmed widespread high-grade copper mineralization while also strengthening our geological model for a potentially significant porphyry system beneath the known skarn mineralization. The upcoming IP survey is a critical step toward identifying the sulphide-rich core of the system and generating high-confidence drill targets. We believe this work has the potential to substantially advance our understanding of the project and unlock its broader district-scale potential."

About the IP Survey

The survey is planned to comprise approximately three kilometres of induced polarization coverage across priority target areas. Scott Geophysics will utilize industry-standard GDD time-domain IP equipment capable of identifying subsurface chargeability and resistivity anomalies commonly associated with disseminated sulphide mineralization. Final survey products will include processed pseudosections, plan maps and digital datasets that will be incorporated into GoldHaven's ongoing geological modelling and exploration planning.
