VANCOUVER, BC / ACCESS Newswire / July 22, 2025 / Star Copper Corp. (CSE:STCU)(OTCQX:STCUF)(FWB:SOP) ("Star Copper" or the "Company"), a critical minerals exploration and development company announced today that concurrent to its summer drill program it has successfully completed an important field program at the Copper Creek target area located within the Company's wholly owned Star Project in northwestern British Columbia's golden triangle.

In addition to the Star Main discovery, historical exploration now confirmed by the Company, has identified at least four additional "fingers" surrounding the Star Main discovery that may each hold significant and complementary discoveries of their own. If successful, the current campaign could prove the entire Star Project as an expansive, mineralized system and deposit.

Located approximately two kilometers (2km) to the southeast of the current drilling campaign, Copper Creek's geological setting, structural complexity, and documented copper grades suggest it may represent a southeastern extension of a broad mineralized system that extends from the Main Zone. Copper Creek holds potential to evolve into a satellite or connecting zone within a larger, continuous copper-bearing trend across the property. The fully funded campaign currently underway is focused on expanding the existing deposit at the Star Project by exploring the historically identified and known mineralization events at Star Main, Copper Creek, Star North, Star East and additional related target locations (See Figure 1).

"We are very encouraged by the results of this recent field work, which confirm historical copper mineralization and provides important geological context for ongoing targeting," said Darryl Jones, CEO of Star Copper. "With Copper Creek located just two kilometres southeast of our current drilling operations at the Main Zone, we see strong potential for this target to evolve into a complementary satellite zone or becoming part of a larger, continuous mineralized system."

Copper Creek's favorable geological setting, structural complexity, and proximity to current exploration activities make it a high-priority target for future work. The Company believes that Copper Creek may represent the southeastern extent of a broader mineralized trend that extends northwest toward and the Main Zone, offering significant upside for resource expansion (See Figure 3).
