Toronto, September 23, 2026 – Highlander Silver Corp. (TSX, NYSE American: HSLV) (“Highlander Silver” or the “Company”) is pleased to announce that it has executed a mandate letter with Natixis Corporate & Investment Banking (“Natixis CIB”) to lead a fully underwritten 7-year senior secured structured project finance facility of $330 million (the “Facility”) to fund the development and construction of the Corani Silver Project in Peru. The financing will be supported by a cost overrun facility of up to $100 million to be established prior to first draw and provided by the Company; final facility amounts will be subject to due diligence. As of June 30, the Company reported a cash balance of approximately $100 million and no debt.

Natixis CIB brings deep expertise in structuring project financing for large-scale mining developments, reinforcing the Corani Silver Project as a globally recognized, bankable asset. The execution of this mandate letter represents a major milestone in advancing towards a fully funded construction package.

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

“Highlander Silver is delighted to partner with Natixis CIB, which is widely regarded as one of the world’s leading project finance institutions, with a distinguished track record of financing successful development projects. The Facility represents a strong endorsement of the Corani Silver Project, providing high-quality capital that follows a rigorous multidisciplinary due diligence process across key technical, financial, environmental and social aspects of the project that set it apart from recent peer financings in the high-yield and convertible debt markets. Importantly, Highlander Silver has retained 100% of the offtake rights to the project to preserve optionality and maximize future value amidst an intensifying global competition for clean concentrates.”

The Facility is subject to completion of definitive documentation, which will include customary project finance terms, fees and conditions, credit approvals, and the completion of ongoing detailed technical, financial, environmental and social due diligence. Closing is expected in the first quarter of 2027.
