Star Copper Corp. (CSE: STCU) (OTCQX: STCUF) (FWB: SOP) (“Star Copper” or the “Company”), a critical minerals exploration and development company, is pleased to provide shareholders with an exploration update from its flagship Star Project in northwestern British Columbia, where ongoing drilling continues to reinforce management’s confidence in the district-scale copper-gold potential of the property.
The first follow-up drill hole of the 2026 project campaign at the Copper Creek location successfully intersected targeted geophysical features which resulted in the technical team at Hardline Exploration subsequently electing to extend drilling beyond the original planned depth after encountering continued alteration, sulphide mineralization, and favourable host rocks below the intended target horizon.
Star Copper’s management believes this development represents an important validation of the Company’s exploration model and further supports the potential for Copper Creek to host a substantial copper-gold mineralized system. The decision to deepen the hole was made based on observations encountered during drilling and reflects the growing confidence of the technical team in the scale potential of the target.
Highlights
- First 2026 follow-up hole at Copper Creek successfully intersected targeted IP chargeability anomaly.
- Hole extended beyond planned depth after encountering continued mineralization below target depth.
- Strong alteration, sulphide mineralization and intrusive-hosted mineralized intervals observed throughout the lower portion of the hole.
- Drilling successfully tested coincident copper-gold soil anomalies and chargeability targets identified through recent exploration.
- Results continue to support Copper Creek as a significant copper-gold target within the broader Star district.
- Additional drilling planned to test the northern and southern extent of the Copper Creek mineralized corridor.
- 3D IP and MT surveys scheduled to further refine district-scale targeting across the Star Project.
CEO Commentary
Darryl Jones, CEO of Star Copper notes, “We are extremely encouraged by the performance of this first follow-up hole at Copper Creek. The hole successfully achieved all its geological objectives and, importantly, continued to encounter encouraging mineralization below our planned target depth. The decision to extend the hole reflects the confidence of our technical team and reinforces our belief that Copper Creek has the potential to host a significant copper-gold system. Over the past two years we have systematically advanced Copper Creek from a historic occurrence into one of the most compelling targets within the Star district. The combination of historical drilling, modern geophysics, strong surface geochemistry and now multiple successful drill holes continues to strengthen our confidence in the scale potential of this target as we work toward establishing a district-scale copper-gold system at Star.”
Drill Hole CC-26-002
DDH CC-26-002 (341941E, 6456452N; azimuth 045°, dip -65°; target depth 200 m; drilled depth 279 m) is the first follow-up hole completed in 2026 at the Copper Creek target, located approximately 2.5 km southeast of Star Main on the south side of the Copper Creek gully. The hole tested a strong IP chargeability anomaly coincident with elevated copper and gold in soil and rock samples identified during the 2025 program, within a structurally complex setting of fractured volcanic rocks intruded by several porphyritic units. Drilling intersected a mixed package of andesite ash tuff, lithic tuff, plagioclase porphyry, and several intervals of crowded pink K-feldspar porphyry (CKP), including a notable intrusive interval from approximately 99.0–108.0 m, with additional CKP dykes at 217.2–218.7 m and 260.3–267.3 m. The presence of CKP is significant as it points to a fertile intrusive component within the Copper Creek system and strengthens the interpretation that the target is preserving the intrusive-volcanic relationships typical of porphyry-style mineralization elsewhere on the Star Project.
Alteration in CC-26-002 is dominated by broad epidote-sericite ± chlorite assemblages with local phyllic overprints and several clear potassic (K-feldspar, magnetite) intervals, most notably from approximately 106.5–132.0 m and again near 138.0–142.2 m, where K-feldspar occurs with silica, chlorite stringers, and locally intensified brecciation and stockwork development. Chalcopyrite was identified in several discrete zones, including 14.1–16.5 m, 83.2–84.0 m, 140.5–151.0 m, 152.0–156.0 m, 157.9–163.1 m, 168.0–168.8 m, 208.5–209.0 m, and 231.0–232.0 m, occurring as fine disseminations, stringers, veinlets, and locally semi-massive sulphide within strongly altered and fractured rock. Several of the better chalcopyrite-bearing zones are spatially associated with potassic alteration, brecciation, and intrusive contacts (see Figure 1), which is encouraging in the context of vectoring toward a larger porphyry center. As with the first Copper Creek hole in 2025, CC-26-002 provides valuable geological information on the architecture and mineralizing controls of the target and continues to support follow-up drilling on both sides of the Copper Creek gully in the 2026 program.
