Star Copper drills Star East target in 15,000 m 2026 exploration campaign

~Company sees ~$4,500,000 in warrants exercised to grow cash balance beyond $15 million VANCOUVER, BC / ACCESS Newswire / June 2, 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 announce the commencement of its 2026 exploration and drill campaign at its flagship Star Project in British Columbia. Operational Update The company is mobilizing on its previously announced fully funded 15,000m drill program at the project. With over $15MM cash-in-hand, the program will double the historic number of meters drilled with the goal of producing a maiden resource ( see news dated April 14, 2026) as well as testing the Company's nested porphyry hypothesis.

Klaus Heppe, Technical advisor ( see news dated May 20, 2026) is working hand-in-hand with Senior Project Geologist Jeremy Hanson at Hardline Exploration Corp. to unearth the increasingly evident potential of the Star Main and satellite targets. The early season program has been designed to test a series of compelling geophysical, geochemical, and structural targets generated through the integration of induced polarization ("IP") chargeability and conductivity anomalies, airborne magnetic data, soil and rock geochemistry, historic trenching, and detailed geological and structural mapping. (See Figure 1) Figure 1-Initial drill targets. Star Copper 2026.

Four drill platforms have now been fully constructed, and the drill has been mobilized to the first pad located within the Star East target area, where drilling is expected to commence this week (see Figure 2). Figure 2-drill installation underway onsite at Star East. Star Copper 2026.

Initial drilling at Star East and Star North will target large chargeability anomalies coincident with elevated copper geochemistry and interpreted structural corridors. Additional drilling planned within the Copper Creek zone will evaluate multiple IP chargeability anomalies associated with coincident copper and gold soil anomalies hosted within strongly altered and fractured volcanic rocks and quartz monzodiorite dike swarms on both sides of the Copper Creek gully system. The drilling here will be to follow up on the successful first hole last year at Copper Creek, ( see news dated March 24, 2026) Darryl Jones, CEO of Star Copper notes, "The start of drilling at Star East marks an important milestone as we launch what is expected to be our largest exploration campaign to date.

The integration of new geophysical data, surface geochemistry, and structural interpretation has significantly refined our targeting across the district. We believe the initial drill holes have the potential to demonstrate the broader scale copper-gold potential of the Star Project beyond the historically drilled Star Main zone." The Company expects the first part of the drill campaign to be followed by expanded drilling activities and additional geophysical surveys, including planned 3D IP and magnetotelluric ("MT") surveys intended to further refine deep porphyry copper-gold targets across the district.

Geo., a Qualified Person as that term is defined under NI 43-101, is an independent contractor of the Company and has reviewed and approved the technical aspects of this news release.

Warrant Exercise Update In related news, Star Copper is pleased to report that all outstanding warrants exercisable at $0.75 per share have now been exercised, resulting in the Company receiving approximately $4,500,000 in additional proceeds bolstering the cash balance of the company to well over $15,000,000 on hand. The complete exercise of these warrants further strengthens the Company's balance sheet and reflects continued support from existing shareholders and warrant holders. The additional capital provides Star Copper with increased financial flexibility as it advances its fully funded 2026 exploration program at the Star Project, including drilling at Star North, Star East, Star West, and Copper Creek, as well as planned 3D IP and MT geophysical surveys designed to refine deeper drill targets at Star Main.
