Strategic Sale of Piedras Verdes Copper Complex

MEXICO CITY, June 24, 2026 — Frontera Copper Corporation, S.A.P.I. de CV, along with Kupari Investments Ltd., have jointly announced the commencement of a strategic sales process for the Piedras Verdes copper mining complex located in the Sonora region of Mexico. This essential step marks a promising opportunity for both companies to capitalize on the rising demand for copper in the global market.

The Piedras Verdes complex boasts a substantial footprint within one of Mexico's most mining-friendly states, Sonora. This region is known for its stable infrastructure and skilled workforce, which can support immediate and future operations efficiently. Given the current supply shortages in copper driven by persisting strong demand and long-term electrification trends, the management believes that this sale could yield significant returns. Furthermore, acquiring this complex offers incoming investors a chance to engage in immediate commercial mining activities and explore avenues for expansion.

To facilitate this strategic initiative, Frontera and Kupari have appointed BMO Capital Markets as the financial advisor. Blake, Cassels & Graydon LLP has been brought on board to provide legal counsel throughout the process. BMO Capital Markets will engage with a variety of potential buyers and will set up a data room to offer confidential information to serious buyers who agree to a confidentiality agreement.
