Goldhaven Announces $2.0 Million Critical Mineral Flow-Through Financing To Advance The District-Scale Magno Polymetallic Project

(MENAFN- GlobeNewsWire - Nasdaq) VANCOUVER, British Columbia, Feb. 19, 2026 (GLOBE NEWSWIRE) -- GoldHaven Resources Corp. (" GoldHaven " or the " Company ") (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) pleased to announce that it intends to complete a non-brokered flow-through private placement financing for gross proceeds of up to $2,000,000 (the“Offering”), through the issuance of up to 7,547,170 flow-through shares at a price of $0.265 per share. The flow-through shares will qualify as“flow-through shares” within the meaning of the Income Tax Act (Canada) and are expected to qualify as“critical mineral flow-through shares.” No warrants will be issued.

The gross proceeds will be used to incur eligible Canadian exploration expenses that qualify as flow-through critical mineral mining expenditures, which the Company intends to renounce to subscribers with an effective date no later than December 31, 2026.

The Company may pay finder's fees in connection with the Offering in accordance with applicable securities laws and exchange policies. Completion of the Offering is subject to customary closing conditions, including regulatory approvals. All securities issued will be subject to a statutory hold period of four months and one day.

“Our 2025 program delivered several milestones with indium values up to 334 ppm - the highest recorded in the Cassiar District - alongside high-grade silver-lead-zinc mineralization, including grab samples returning up to 2,370 g/t silver with more than 20% lead and 19.25% zinc. Strong and widespread tungsten mineralization, particularly at the Kuhn and Dead Goat Zones, further confirms the scale of the system. The property-scale metal zonation we've mapped - from Ag-Pb-Zn carbonate replacement to tungsten-zinc skarns and a porphyry Cu-Mo source - is characteristic of a large, intrusion-driven mineral system. This financing allows us to complete 3D targeting and advance toward 2026 drilling.” Robert Birmingham, President and CEO of GoldHaven Resources Corp.

Highlights

• 334 ppm Indium Discovery Confirms Critical Mineral Potential – Indium values up to 334 ppm associated with sphalerite (Zn), representing the highest recorded in the Cassiar District and underscoring Magno's strategic relevance amid rising indium prices and global supply constraints.
• High-Grade Silver-Lead-Zinc Results* – Grab samples returned up to 2,370 g/t Ag, >20% Pb, and 19.25% Zn from the Magno and D Zones, with 45 of 357 samples exceeding 100 g/t Ag, confirming widespread high-grade mineralization.
• Strong & Widespread Tungsten Mineralization – 32 samples returned >1,000 ppm W, including a peak of 6,550 ppm W at Vines Lake and consistent 500–5,000 ppm W at Kuhn and Dead Goat
• Fully Funded Advancement Strategy – $2.0 million flow-through financing at $0.265 (no warrants) supports 2026 3D modelling, target refinement, and drill planning while continuing verification of historical showings and expansion of newly identified targets across the district.

*Grab samples are selective by nature and may not represent average grades of mineralization.

2025 Exploration Program Summary

The 2025 exploration program significantly advanced understanding of Magno as a large, zoned hydrothermal system and confirmed the presence of mineralization across multiple zones.

Key results include:

• Copper values up to 6,660 ppm, including elevated copper within granite
• Zinc up to 13.8% at Kuhn and 8.37% at Dead Goat
• Bismuth up to 10,000 ppm and tellurium up to 67 ppm possibly indicating high-temperature fluid pathways
• Strong Ag-Pb-Zn mineralization confirmed at Magno and D Zones
• Tungsten mineralization consistent with high-temperature skarn systems
• Elevated indium associated with zinc mineralization

The observed Metal distribution suggests classic porphyry-related zonation transitioning from intrusive proximal Cu-Au-Ag mineralization to intermediate Ag-Pb-Zn replacement systems and distal structurally controlled mineralization.

The highest silver, lead, and zinc grades occur at the Magno and D Zones, confirming robust replacement-style mineralization. Elevated copper values occur across multiple zones and within intrusive rocks, supporting interpretation of a magmatic metal source. Tungsten mineralization at Kuhn and Dead Goat further confirms high-temperature fluid processes consistent with porphyry-skarn systems.

Strong bismuth, tellurium, and antimony enrichment highlight deep structural fluid pathways and high-temperature vectors, reinforcing the scale and intensity of the mineralizing system.

Metal ratio signatures suggest property-scale deposit zonation driven by a porphyry intrusive system. The transition from Pb-Ag-rich carbonate replacement at Magno and D Zones (low Zn/Pb ratios 0.79-6.13, very high Pb/Cu ratios 123-1,469) to Zn-W-dominant skarns at Kuhn and Dead Goat (extremely high Zn/Pb ratios 190-1,342, low Pb/Cu ratios 3.88-15.12) may reflect increasing proximity to high-temperature intrusive source. This is characteristic of porphyry-related systems where distal CRD-style Ag-Pb-Zn gives way to proximal skarn-hosted Zn-W-Cu. Progressive enrichment in high-temperature pathfinders (Bi to 10,000 ppm, Te to 67 ppm) and elevated Cu-in-granite (6,660 ppm) further support magmatic metal source at depth.

Magno Project:

GoldHaven's Magno Project is a district-scale polymetallic exploration asset spanning approximately 36,973 hectares in the prolific Cassiar region of northwestern British Columbia. The project hosts a large intrusion-related hydrothermal system including copper-gold, silver-lead-zinc, tungsten-skarn, and critical-mineral mineralization.

Property-wide geological mapping, sampling, and geochemical analysis define a classic porphyry-related metal zonation pattern, supporting interpretation of a large mineralizing system with stacked deposit environments and strong structural controls.

Magno - Key Geological Highlights

• Property-scale metal zonation consistent with a porphyry source system
• Stacked mineralization including porphyry, CRD, and skarn environments
• Verified historical Ag-Pb-Zn mineralization at Magno and D Zones
• Confirmed tungsten mineralization at Kuhn and Dead Goat
• Elevated copper within intrusive rocks supports magmatic metal source
• Strong critical-metal association including indium, bismuth, and tellurium

Magno is located just three kilometres south of the historic Cassiar mining camp and is accessible via Highway 37, providing infrastructure advantages rarely present at projects of this scale. The property borders claims held by established operators, positioning GoldHaven within a proven regional mining corridor.

2026 Exploration Program

GoldHaven will use the expanded geological and geochemical dataset to advance Magno toward drill testing and scale of the mineral system.

Planned work includes:

• Refinement of 3D geological and metal zonation models
• Integrated structural, geochemical, and geophysical interpretation
• Prioritization of porphyry CRD Ag-Pb-Zn, tungsten-skarn, and critical-mineral targets
• Drill targeting across priority zones
• Advancement of permitting and preparation for potential drilling
  

The 2026 program is designed to test system scale, vertical extent, and higher-grade vectors across the Magno district.
