GoldHaven Resources Acquires Claims Within Magno Project

Vancouver, British Columbia – (GlobeNewswire) – October 31 st, 2025 - GoldHaven Resources

Corp. (“GoldHaven” or the “ Company”) (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to

announce that it has entered into an agreement to acquire the Hamel claims (the “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 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 but now showing potential for

indium and gallium. Comparisons to 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 (the “Agreement”) dated October 23, 2025,

with Robert Joseph Hamel (the “Vendor”), under which the Company will acquire a 100% interest in

the Claims situated in the Cassiar Mining District, British Columbia (the “Transaction”).

As consideration, GoldHaven will pay $10,000 CAD in cash and issue 300,000 common shares (the

“Consideration Shares”) to the Vendor. All Consideration Shares will be subject to a standard

Canadian statutory four-month hold period.

exploration potential, and consolidating key ground positions is an important step in unlocking value

for our shareholders.”
