STAR COPPER TO DEPLOY ADVANCED DEEP-PENETRATING 3D IP TO EXPEDITE 2026 DRILL PROGRAM

Star Copper Corp. is preparing to mobilize an advanced, cutting-edge, deep-penetrating geophysical survey at its flagship Star project aimed at advancing its exploration strategy.

Executive summary

Star Copper has committed to undertaking a technology-focused survey at its flagship Star project in northwestern British Columbia. The survey will utilize advanced multiparameter distributed technology developed by Quantec Geoscience, a global leader in deep-imaging geophysical solutions, and represents a key technical milestone in advancing the company's exploration strategy toward an aggressive 2026 drill program.

Highlights:

• Deep-penetrating Orion Swath 3-D IP (induced polarization) to tighten geophysical model;
• Calk-alkaline porphyries benefit greatly from MT (magnetotelluric) and 3-D IP;
• Capable to depths of 750 to 1,500 metres and beyond;
• Survey has been instrumental in other world-class deposit definition in the area.

Star Copper chief executive officer Darryl Jones noted: "This technology is particularly well suited for porphyry copper exploration in British Columbia, where many deposits extend well below the limits of conventional geophysical methods and early-stage drilling. Notably, deep-penetrating IP and MT technologies developed by Quantec were instrumental in advancing the geological understanding of the Red Chris mine, where deeper high-grade mineralization was identified beneath the known deposit, demonstrating the importance of imaging the full vertical extent of porphyry systems."

Results from the Orion survey will be fully integrated into the company's evolving three-dimensional geologic model and are expected to directly inform drill targeting, hole orientation and depth selection for a planned aggressive 2026 drill program. By identifying deep-seated chargeability and resistivity anomalies associated with potential intrusive centres and mineralized feeder structures, the company aims to prioritize high-impact drill targets capable of materially advancing the scale and quality of mineralization at the Star project.

The Orion system is designed to provide accurate, high-resolution images of the subsurface by simultaneously measuring resistivity and chargeability using distributed acquisition methods. This approach delivers unparalleled depth of investigation and superior subsurface sampling for DC (direct-current) resistivity and induced polarization (IP) parameters. These data are integrated with magnetotelluric (MT) resistivity measurements, which record naturally occurring electric and magnetic fields and are densely sampled across the survey array.

Together, the Orion DC-IP and MT data provide a comprehensive three-dimensional rendering of subsurface chargeability and resistivity to depths exceeding approximately 750 metres, with deeper resistivity imaging extending to 1,500 metres and beyond. This level of depth penetration allows the company to evaluate large-scale geological architecture, including deep intrusive bodies, major structures and potential feeder zones that are critical components of large porphyry copper-gold systems.

The company believes that combining deep-penetrating geophysics with disciplined geological modelling positions Star Copper to efficiently deploy capital and maximize discovery potential as it transitions into its next phase of systematic drilling.

About Star Copper Corp.

Star Copper is a Canadian mineral exploration company focused on the discovery and advancement of large-scale copper-gold systems in British Columbia. The company's flagship Star project is located in British Columbia's prolific Golden Triangle and hosts multiple high-priority targets and exhibits geological characteristics consistent with significant porphyry copper deposits. The project hosts multiple copper-gold porphyry-style targets, including Star Main, Star North, East and West, Copper Creek, and Copperline. Significant exploration, including historical drilling, has confirmed open mineralization at depth and in all directions. Star Copper's strategic plans include geological mapping and geophysical surveys to refine existing targets, diamond drilling programs to test high-priority zones, environmental baseline studies and permitting groundwork alongside data analysis and resource modelling to support a future resource estimate prepared in accordance with NI 43-101. The company further plans to advance its Indata project with follow-up drilling to expand on previous high-grade copper and gold intercepts, trenching and surface sampling to delineate mineralized zones, and infrastructure improvements for site accessibility and operations. With a commitment to sustainable development and value creation, Star Copper aims to position itself to support surging industrial demand to meet growing global electrification needs.
