AMERIGO PROVIDES UPDATE ON MVC OPERATIONS

Amerigo Resources Ltd. has provided an operational update on Minera Valle Central, the company's 100-per-cent-owned operation located near Rancagua, Chile.

During the evening of July 31, 2025, a seismic event triggered a rockfall in the Andesita sector of El Teniente underground mine, which is owned by Corporacion Nacional del Cobre de Chile (Codelco) and provides fresh tailings to MVC. Several mine workers were trapped in the mine, and, per standard procedure, Codelco suspended operations at El Teniente and commenced search and rescue efforts immediately. Sadly, the collapse led to the death of six workers. After Codelco's search and rescue mission concluded on Sunday, Aug. 3, Chile's President Gabriel Boric declared three days of national mourning.

Until El Teniente resumes operations, MVC will focus on processing historic tailings. The impact on the company's annual production guidance cannot be quantified at this stage, but will depend on how long mining operations at El Teniente remain suspended. Currently, the daily loss of copper production at MVC is estimated at 100,000 pounds per day.

This tragic event deeply saddens everyone at Amerigo and MVC.
