VANCOUVER, BC / ACCESS Newswire / June 23, 2026 / Star Copper Corp. (CSE:STCU)(OTCQX:STCUF)(FWB:SOP) ("Star Copper" or the "Company"), a critical minerals exploration and development company, is pleased to provide shareholders with an exploration update from its flagship Star Project in northwestern British Columbia, where ongoing drilling continues to reinforce management's confidence in the district-scale copper-gold potential of the property.

The first follow-up drill hole of the 2026 project campaign at the Copper Creek location successfully intersected targeted geophysical features which resulted in the technical team at Hardline Exploration subsequently electing to extend drilling beyond the original planned depth after encountering continued alteration, sulphide mineralization, and favourable host rocks below the intended target horizon.

Star Copper's management believes this development represents an important validation of the Company's exploration model and further supports the potential for Copper Creek to host a substantial copper-gold mineralized system. The decision to deepen the hole was made based on observations encountered during drilling and reflects the growing confidence of the technical team in the scale potential of the target.
