Star Metro - PPX Mining Provides Update on Start-up of the Process Plant

The Company's process plant and ancillary infrastructure have been duly approved by the Regional Ministry of Mines and were designed in accordance with all applicable technical and environmental standards. The Project incorporates a geotube-based tailings management system, which eliminates the need for a conventional tailings dam and enables the recycling of process water as part of the operation. These technical aspects are among the matters the Company intends to further explain and clarify through the working group process in order to provide additional comfort to the surrounding communities.

The permitting process for the Project was supported by an extensive community engagement program, including public participation forums held in 2018 and 2023 that were attended by community members and local stakeholders, during which no objections to the Project were presented. Nevertheless, the Company believes it is important to revisit and refresh these technical discussions with the communities to ensure that all stakeholders continue to have a clear and updated understanding of the Project's design, environmental safeguards, and operating methodologies.

In the interim, ore from the Callanquitas Mine will continue to be processed at third-party facilities, consistent with current operations. The Company expects operating performance to remain in line with recent quarters (see press releases dated February 11, 2026 and May 5, 2026).

No changes to the Company's 2026 exploration plans are anticipated.
