MEXICO CITY, June 24, 2026 /PRNewswire/ —** Frontera Copper Corporation, S.A.P.I.
de CV** and **Kupari Investments Ltd. **("Kupari"), collectively the "Companies",
announced today that Frontera Copper Corporation ("Frontera"), and Kupari Metals
A.G., a wholly-owned subsidiary of Kupari, have commenced a strategic sale process
for the Piedras Verdes mine complex. Any mention of the Piedras Verdes mine complex
refers to 100% of the equity in both Frontera and Kupari Metals. The Companies have
retained BMO Capital Markets as financial advisor and Blake, Cassels & Graydon LLP
as legal advisor in connection with the process.

Piedras Verdes is a producing copper mine located in the stable and mining-friendly
state of Sonora, Mexico, with nearby access to supportive infrastructure and a skilled
workforce. As a result of copper supply shortages due to continued strong copper
demand, secular electrification trends, and lengthy development processes, management
believes that a sale today has the potential to generate significant proceeds, while
acquirers can benefit from immediate commercial production and expansion opportunities.

BMO Capital Markets has begun speaking with a number of prospective acquirers and
the Companies will be opening a data room with confidential information to potential
acquirers who have entered into satisfactory confidentiality agreements.
