Arizona Tribune - Star Copper Phase 2 Drill Preparation Uncovers Significant Mineralization at Surface

Once Phase 2 drilling commences, Hole G (S-056) is located to the south of the Star Fault zone, a roughly planar structure marked by broken, clay-rich gouge, and will be drilled to 500m to test targets that Hole D was unable to fully intersect. The hole is collared ~130m south of Hole D (S-053B) and ~100 m west of Hole F (S-055) (UTM 339,691E / 6,458,142N, elevation 1,050 m; azimuth 000°, dip -75°; planned depth 500m) and is positioned to further evaluate the southwest extension of magnetic and induced polarity anomalies (see Figure 3).

Geologically, Hole G is designed to pierce near-surface supergene copper mineralization where copper occurs as malachite and azurite along oxidized fractures, before stepping down into the hypogene domain where copper is hosted as chalcopyrite (cpy). The hole is set to cross a corridor of mineralized quartz monzodiorite (QMD) identified in Hole F (S-055), where recent drilling documented cpy as fine disseminations and within sheeted quartz-pyrite-chalcopyrite-K-feldspar veinlets, later quartz-calcite-chlorite-pyrite-cpy veins, and pyrite-cpy stringers. At depth (>300 m), Hole G aims to evaluate a hypogene Cu ± Au zone intersected in historical hole S-040, tying intrusive phases, potassic (potassium-feldspar) alteration, and structural corridors together across the south side of the Star Fault zone.

Company CEO Darryl Jones notes, "By re-testing the target that Hole D could not fully evaluate and by stepping west from Hole F, our upcoming Hole G is positioned to confirm and extend the copper footprint of Star Main to the southwest, clarify grade-control architecture in the footwall of the Star Fault zone, and strengthen links between oxidation profiles, potassic alteration, and hypogene sulphide mineralization. As the first hole of Phase 2, it marks the transition from Phase 1's mapping of structure and alteration to targeted drilling that advances continuity and scale across Star Main."

Copper Creek Project Area Access Established with Mapping and Sampling Underway

Copper Creek offers a whole new area that has confirmed copper mineralization from historic drilling which could extend the Star deposit and unlock huge value. Plans are being formulated to drill copper creek with the extension of the ongoing exploration program.

Copper Creek's favorable geological setting, structural complexity, and proximity to current exploration activities has earned it a place as a high-priority target for the Company. Copper Creek may represent the southeastern extent of a broader mineralized trend that could extend northwest toward the Main Zone, offering significant upside for resource expansion.

Crews have recently established ground access to the Copper Creek Zone, located 2.5km southeast of Star Main (see Figure 4)

Recent field work has validated historical exploration records and established a reliable geospatial foundation for exploration. Mapping and sampling of the roughly 2km x 1.5km Cu+/-Au in soil anomaly is underway and insights from this program will inform potential drilling in the later stages of Phase 2 drilling at the Star Property. See Company news release of July 22, 2025 for additional information.

About Star Copper Corp. (CSE: STCU) (OTCQX: STCUF) (FWB: SOP / WKN A416ME)

Star Copper Corp. is an exploration and development company focused on developing high-potential copper projects in mining-friendly jurisdictions. The Company aims to advance its British Columbian flagship Star Project where significant exploration work 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 modeling 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.
