GOLDHAVEN RESOURCES ACQUIRES CLAIMS WITHIN MAGNO PROJECT

Goldhaven Resources Corp. has entered into an agreement to acquire the Hamel claims located in northwestern British Columbia, within the company's Magno project area. The newly acquired claims cover 429.46 hectares and further demonstrate Goldhaven's commitment to consolidating its district-scale land position in this highly prospective region.

Magno project

The Magno project hosts multiple mineralization styles linked by common fluid pathways and heat sources, suggesting a related series of mineralizing events. Recent fieldwork identified the Cassiar stock -- a 72 Ma (million years ago) Cretaceous granite along the Cassiar batholith's eastern margin -- as a key control on mineralization. Mapping confirmed a strong correlation between phases of the Cassiar stock and mineralized showings, prompting Goldhaven to expand the project to 36,002.99 hectares to consolidate the system. Early work has connected mineralized skarns along north-south and northeast-trending structures where Cassiar stock intrudes Cassiar terrane sediments. At Magno Central (Magno and D zones), structurally controlled skarn and CRD-style mineralization occur within the Rosella formation, historically known for Ag-Pb-Zn (silver-lead-zinc) but now showing potential for indium and gallium. Comparisons with Coeur Mining's Silvertip project highlight strong regional potential, while mapping in the Kuhn and Dead Goat zones identified skarns dominated by diopside-garnet with zones of tremolite, pyrrhotite and scheelite.

Terms of the agreement

Goldhaven has entered into a title transfer agreement dated Oct. 23, 2025, with Robert Joseph Hamel (the vendor), under which the company will acquire a 100-per-cent interest in the claims situated in the Cassiar mining district, British Columbia.

As consideration, Goldhaven will pay $10,000 in cash and issue 300,000 common shares to the vendor. All consideration shares will be subject to a standard Canadian statutory four-month hold period.

Rob Birmingham, chief executive officer of Goldhaven Resources, commented, "The acquisition of the Hamel claims strengthens our strategic land position within the Magno project and underscores our commitment to building a district-scale mining portfolio in British Columbia." Mr. Birmingham commented, "We believe this area holds strong exploration potential, and consolidating key ground positions is an important step in unlocking value for our shareholders."
