Star Copper Drill Program Mobilizes Additional Rig at Copper Creek to Test High Value Historic Target in BC

VANCOUVER, BC / ACCESS Newswire / October 14, 2025 / 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 it has finalized preparations for a maiden drill program at its Copper Creek target located just 2 kilometers from the Star Main drill campaign at the flagship Star Project in northwestern British Columbia. The Copper Creek target has advanced to a drill-ready stage following extensive geological, geochemical, and geophysical work programs. The Company is eager to test the historic holes and validate additional targets to confirm a larger porphyry deposit.

Copper Creek Target Overview
Copper Creek is characterized by two strong copper-in-soil anomalies extending over an area approximately 550 metres by 1,000 metres, with anomalous values remaining open to the north, south, and east. Extensive malachite-azurite gossans are exposed at surface, coinciding with elevated Cu and Au in soils and chargeability highs from induced polarization (IP) surveys (See Figure 1).

The main showing hosts copper oxides, chalcopyrite, and pyrite within strongly propylitically altered volcanics along an east-trending structural zone. Field mapping and rock sampling have confirmed that copper mineralization is structurally controlled, with several high-grade exposures exceeding 5,000 ppm Cu (XRF) identified along bluffs during earlier work (See Figure 2).

Historic and Recent Work
Historic exploration programs include prospecting, trenching, limited drilling (1970), and 2013 geophysical and geochemical surveys. The 2013 IP survey and total magnetic intensity (TMI) data were recently reinterpreted using 3D inversion and Leapfrog modelling, integrating historic drill and soil datasets. Follow-up fieldwork in 2025 confirmed structural orientations influencing mineralization and validated proposed collar locations (See Figure 3).

Planned Drill Program
The helicopter-supported drill program is scheduled to begin following completion of pad construction. Two initial holes, totaling approximately 400 metres, are planned to test:

• Historic mineralized intervals identified in prior drilling
