GoldHaven Reaches 3,000 Metres Drilled at Magno, Advances High-Grade Silver-Lead-Zinc Targets in British Columbia's Cassiar District

Drilling continues at D Zone as GoldHaven explores a silver-rich mineralized system sharing key geological characteristics with Coeur Mining's Silvertip deposit

VANCOUVER, British Columbia, Oct. 29, 2026 (GLOBE NEWSWIRE) -- GoldHaven Resources Corp. ("GoldHaven" or the "Company") (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to announce that its inaugural 2026 diamond drilling program at its flagship Magno Project in northwestern British Columbia has reached approximately 3,000 metres, with exploration advancing across its high-grade silver-lead-zinc and tungsten targets.

Recent drilling at D Zone has encountered multiple intervals of semi-massive to massive sulphide mineralization, further advancing GoldHaven's exploration of a silver-lead-zinc system sharing key geological characteristics with Coeur Mining's Silvertip deposit. Drilling continues across additional targets, with laboratory assays pending.

Highlights

• Over 3,000 metres drilled: GoldHaven reaches a significant milestone in its inaugural 2026 drilling program at Magno, targeting both silver-lead-zinc and tungsten mineralization.
• High-grade historical silver: Previous D Zone drilling reported 7.6 metres grading 240 g/t silver, 4.73% lead and 4.74% zinc.
• High-grade silver surface samples: GoldHaven's 2025 exploration program returned up to 2,370 g/t silver at Magno and 1,390 g/t silver at Middle D.
• Silvertip geological comparison: Magno exhibits carbonate replacement-style mineralization, including manto and chimney-style features also characteristic of Coeur Mining's Silvertip deposit.
• Additional massive sulphides intersected: Drill hole GOH26-15 encountered approximately 18.5 metres of massive sulphide and 9 metres of semi-massive sulphide mineralization, with assays pending.
  
  

Advancing Silver-Lead-Zinc Exploration at D Zone

Further to the Company’s October 22nd news release, which described four of the first five completed drill holes at Middle D intersecting semi-massive to massive sulphide mineralization, the latest diamond drill hole in this area (GOH26-15) has intersected approximately 18.5 m and 9 m of massive sulphide and semi-massive sulphide mineralization, respectively. This is in addition to the previously announced GOH26-10 and GOH26-13 which encountered cumulative visually identified mineralized intervals of approximately 10.75 metres and 13 metres, respectively, across separate intervals. True widths are unknown.

The mineralization includes visible galena and sphalerite, with drilling continuing to evaluate the geometry and potential continuity of the system. Laboratory assays remain pending.

CEO Commentary:

"Reaching 3,000 metres in our inaugural drill program is an important milestone, but we're particularly encouraged by the silver-lead-zinc potential emerging at D Zone," commented Rob Birmingham, President and CEO of GoldHaven.

"Magno shares compelling geological characteristics with Coeur Mining's Silvertip deposit. With multiple sulphide intersections and assays approaching, we're excited to further evaluate the potential of this system."

GoldHaven's Magno Project Shares Key Geological Characteristics with Coeur Mining's Silvertip Deposit

GoldHaven's Magno Project is situated within the Cassiar Terrane of northern British Columbia, the same regional geological setting that hosts Coeur Mining's Silvertip silver-lead-zinc deposit, a well-established carbonate replacement deposit (CRD).

Magno exhibits several geological characteristics associated with the Silvertip model, including carbonate-hosted silver-lead-zinc mineralization, manto- and chimney-style replacement features, and multiple mineralized zones. These similarities provide an established exploration framework for evaluating the broader potential of Magno's polymetallic system.

GoldHaven is integrating modern geophysical data, geological mapping and ongoing drilling to better understand the distribution and potential continuity of mineralization across its more than 37,000-hectare property.

The comparison is geological in nature only. Mineralization at Silvertip is not necessarily indicative of mineralization at Magno, and no mineral resource has been established at D Zone.

Next Steps

GoldHaven's near-term exploration activities include:

1. Continuing drilling across additional targets within the D Zone system.
2. Completing laboratory analysis and reporting assay results following QA/QC review.
3. Integrating geological, geochemical and geophysical datasets to evaluate the distribution and potential continuity of mineralization.
   
   

The Magno Project covers more than 37,000 hectares in the Cassiar District and hosts multiple exploration targets, including silver-lead-zinc mineralization at D Zone and Magno, together with tungsten-bearing skarn systems at Kuhn and Dead Goat.

Technical Notes

The historical 7.6-metre D Zone intersection has not been independently verified and is not necessarily indicative of current drill results. Previously reported sulphide intervals are cumulative visual downhole measurements from separate intervals, not true widths, and do not establish laboratory assay grades or economic mineralization. Grab samples are selective and are not representative of deposit-wide grades.
