Highlander Silver Provides Update; Drilling Commences at Corani Silver Project

Toronto, April 7, 2026 – Highlander Silver Corp. (TSX, NYSE American: HSLV) (“Highlander Silver” or the “Company”) is pleased to provide a portfolio update following the successful completion of its combination with Bear Creek Mining (see press release dated February 26, 2026).

Daniel Earle, President and CEO of Highlander Silver, commented:

“Highlander Silver is well positioned to fast-track project advancement across its portfolio of high-quality silver assets. This includes a focus on high-impact exploration, project optimization, and site preparation for development of Corani, the largest fully permitted primary silver project in the world, as well as permitting at San Luis, one of the highest M&I resource grade projects in both the gold and silver sectors.

As of March 31, the Company had an unaudited cash balance of approximately US$100 million and no debt. The Mercedes gold-silver mine also made a positive cash contribution in its first month of operations following restructuring under our stewardship. We provide a summary of our baseline plans below and forecast a year-end cash balance of approximately US$60 million. This reflects a disciplined approach to spending that delivers on our core objectives while preserving flexibility to scale up our exploration programs later in the year.”
