Northisle Copper and Gold Inc. Commences Trading on the OTCQX Market Under the Symbol NTCPF

Sam Lee, President & CEO stated "We are excited to begin trading on OTCQX, which will provide greater accessibility and visibility for Northisle among U.S. investors as we continue advancing our compelling North Island copper-gold project. With a recently completed PEA outlining a C$2.0 billion after-tax NPV and a 29% IRR, and a 2025 exploration program already underway targeting higher-margin zones and new porphyry centers, Northisle is at an inflection point. Our focus on responsible development, stakeholder engagement, and district-scale opportunity in a tier-one jurisdiction positions us to deliver long-term value. We look forward to welcoming new shareholders to participate in this exciting phase of growth."

Upgrading to the OTCQX Market is an important step for companies seeking to provide transparent trading for their U.S. investors. For companies listed on a qualified international exchange, streamlined market standards enable them to utilize their home market reporting to make their information available in the U.S. To qualify for OTCQX, companies must meet high financial standards, follow best practice corporate governance and demonstrate compliance with applicable securities laws.
