"We are thrilled with the strong interest from investors and the resulting upsizing of the financing from $3.5-million to $10-million," said Niel Marotta, chief executive officer of Sun Summit. "These funds will support a 5,000-metre drill program at JD this summer, which is double what we completed during our inaugural season in 2024. The program will focus on the highly-prospective Creek-to-Finn corridor, where we aim to expand the footprint of known mineralization along strike at the Creek and Finn targets as well as testing new targets within and outside the corridor. Corporate activity across the Toodoggone has accelerated in 2025, reinforcing the district's strong potential. It's an exciting time for Sun Summit: We are well funded and ready to build on last season's momentum with an aggressive exploration program in one of Canada's most active and promising regions."
