NEWS RELEASE

PPX MINING PROVIDES UPDATE ON START-UP OF THE PROCESS

PLANT

Toronto – May 11, 2026 – PPX Mining Corp. (TSX.V PP X; BVL PPX) (the “Company” or

“PPX”) announces the establishment of a working group wit h the Municipality of Huaranchal,

representatives of the local communities, and the Regional Government of La Libertad, following

recent meetings during which certain concerns and misunderstandings were raised by community

members regarding aspects of the Project’s planned operations. The working group is intended to

provide a constructive forum to clarify technical and operational matters, address questions raised

by stakeholders, and support a transparent and coll aborative path forward for the Project. While

this decision will result in a delay in the start-up of the process plant currently under construction,

the Company believes that preserving a constructive partnership with local communities that have

hosted the project operations for more than a decad e is fundamental to the Project’s long-term

success.

The Company’s process plant and ancillary infrastructure have been duly approved by the Regional

Ministry of Mines and were designed in accordance w ith all applicable technical and

environmental standards. The Project incorporates a geotube-based tailings management system,

which eliminates the need for a conventional tailin gs 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 supporte d 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 wh ich 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, envi ronmental 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.
