The TSX Venture Exchange has accepted for filing a definitive earn-in agreement dated Dec. 19, 2025, between Westhaven Gold Corp. and Dundee Corp., pursuant to which the company has granted Dundee the sole and exclusive right to acquire up to an aggregate 60-per-cent undivided interest in the Shovelnose gold project, Prospect Valley gold project, Skoonka gold project and Skoonka North project, located in British Columbia.

To earn the full 60-per-cent interest, Dundee must finance a total of $85-million in operations expenditures over a period of up to seven years in four stages: a 25-per-cent interest for $30-million within three years; a 12.5-per-cent interest for $15-million within five years; an additional 12.5-per-cent interest for $20-million within six years; and a final 10-per-cent interest for $20-million within seven years. The initial $30-million financing requirement is a firm commitment and any shortfall is payable to the company in cash should Dundee terminate the agreement prior to acquiring the first 25-per-cent interest.

The projects will be held by a newly incorporated joint venture company governed by a shareholders' agreement that provides for a board of directors and operatorship structure that adjusts according to the parties' respective interests
