GoldHaven Resources Expands Magno Project to Over 37,200 Hectares with Strategic Cassiar Claims Acquisition

VANCOUVER, British Columbia, Feb. 27, 2026 (GLOBE NEWSWIRE) -- GoldHaven Resources Corp. (“GoldHaven” or the “Company”) (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to announce that it has entered into a Title Transfer Agreement dated February 23, 2026, with Steven Scott (the “Vendor”) to acquire a 100% interest in five mineral claims located in the Cassiar District of British Columbia (the “Property”). The Property comprises 231.362 hectares across five contiguous mineral claims (Claim Nos. 1127358, 1118681, 1117996, 1126824 and 1124840), with the project now spreading 37,204 hectares.

“Expanding Magno beyond 37,000 hectares further strengthens our control over what we interpret to be a large, zoned, intrusion-related polymetallic system,” commented Rob Birmingham, CEO of GoldHaven. “The confirmation of high-grade silver-lead-zinc mineralization, extensive tungsten-skarn development, elevated copper within intrusive rocks, and strong bismuth-tellurium pathfinder anomalies supports a porphyry-driven model at depth. With infrastructure in place and a rapidly advancing geological framework, we are positioning Magno for a disciplined 2026 drill program targeting copper-moly porphyry centres, CRD-style silver-lead-zinc zones, and critical-mineral potential across this district-scale asset.”

Pursuant to the terms of the agreement, the Company will issue an aggregate of 400,000 common shares (the “Compensation Shares”) to the Vendor as consideration for the acquisition. The Compensation Shares will be subject to a statutory hold period of four months and one day from the date of issuance in accordance with applicable securities laws. The Vendor will retain no net smelter return royalty or other encumbrance on the claims, and the Company will assume responsibility for applicable title transfer costs.

GoldHaven’s Magno Project is a district-scale polymetallic exploration asset spanning approximately 37,204 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.

The newly acquired claims strategically expand GoldHaven’s land position in the Cassiar camp, an area known for its polymetallic mineralization including tungsten, molybdenum, silver, lead and zinc. The Company believes the addition of these claims enhances its district-scale exploration footprint and provides further optionality for future exploration and development initiatives in the region.

The Company is advancing its previously announced non-brokered flow-through financing of up to $2,000,000 through the issuance of flow-through common shares at a price of $0.265 per share. Proceeds will be used to incur eligible Canadian exploration expenses at the Magno Project in British Columbia, including permitting, drill targeting, and advancement of priority copper-gold, silver-lead-zinc (CRD), tungsten-skarn, and critical-mineral targets.

The offering remains subject to customary closing conditions and regulatory approvals. The Company may pay finders’ fees in accordance with applicable securities laws and exchange policies.

GoldHaven will leverage its expanded geological and geochemical dataset to advance Magno toward drill testing and evaluation of system scale.
