NEW AGREEMENT REINFORCES MVC'S LEADERSHIP POSITION AS AN EMPLOYER OF CHOICE IN CHILE 3-YEAR COLLECTIVE AGREEMENT WITH SUPERVISORS WILL RUN FROM JANUARY 8, 2027 TO JANUARY 8, 2030

Amerigo Resources Ltd.'s 100-per-cent-owned subsidiary, Minera Valle Central (MVC), has completed an anticipated negotiation with its 74-member Supervisors' Union. The result is a new three-year collective agreement that will become effective on Jan. 8, 2027, and will continue through Jan. 8, 2030.

"Completing this negotiation ahead of schedule and in a constructive environment is a positive outcome for both MVC and the Supervisors' Union. It reflects the quality of the working relationship we have built, and our shared interest in maintaining stable, uninterrupted operations," said Aurora Davidson, president and chief executive officer of Amerigo Resources.

The Supervisor's Union negotiation was carried out under an "anticipated negotiation" process. In Chile, this process allows the parties to address the terms of the next collective agreement well in advance of the statutory timeline.

The process was completed in record time, reflecting a constructive and collaborative approach from both MVC and the Supervisors' Union. By reaching an agreement ahead of schedule, the parties have fully eliminated the risk of labour disruption associated with the 2027 bargaining period, including the potential for strike action.

MVC also has in place a collective agreement with its Operators' Union with a term from Oct. 29, 2025, to Oct. 29, 2028.
