Star Copper Corp. (OTCQX:STCUF) has completed its Summer 2025 Phase 1 drilling program at its flagship Star Project in northwestern British Columbia. The program included six drill holes totaling over 2,200m, with the deepest hole reaching 675m. Key achievements include:

The drilling campaign successfully expanded the near-surface supergene footprint by 75m to the southwest and confirmed copper mineralization across multiple intrusive phases. The supergene zone at Star Main, a rare find in this area of Canada, now extends to 250m x 300m. The company has already initiated plans for Phase 2 drilling in fall 2025, targeting step-outs and deeper tests at Star Main, Star North, and Copper Creek.

Additionally, Star Copper announced a $1,000,000 marketing services agreement with Upswitch Media Corp. for a 60-day term to expand company awareness and investor relations.

Company confirms and expands project scope and fine tunes targeting for Phase 2 drilling

VANCOUVER, BC / ACCESS Newswire / September 2, 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 report the completion of its Summer 2025 Phase 1 drilling and related exploration activities at its flagship Star Project in northwestern British Columbia.

Phase 1 drilling was designed to test the grade/fault relationship to better target and understand the overall orientation and mineralization of the Star Deposit. The company drilled the deepest hole to date at 675m in Hole C (S-052) which notably intersected overprinted potassic mineralization. Drilling was also successful in confirming and expanding the supergene footprint by 75 m to the southwest and the overall results were instrumental in the Company's election to advance into a Phase 2 drill campaign almost immediately.

The fully integrated program combined a maiden drilling campaign at Star Main with systematic mapping and sampling across the broader property. The six-hole drill campaign (see Figure 1) consisted of target holes 2025 A-F (S-050, S-051, S-052, S-053B, S-054A, S-055) and totaled over 2200m which culminated with the recently completed Hole S-055 (2025-F) which intersected a near-surface oxide horizon with visible malachite and azurite (see news release of August 25, 2025) and transitions at depth to chalcopyrite in mineralized quartz monzodiorite, consistent with our oxide-to-hypogene model along major structures.

The Phase 1 drilling expanded the near-surface supergene footprint to the west and southwest, confirmed copper mineralization across multiple intrusive phases, and sharpened the structural and alteration framework, particularly along the Star Fault and associated potassic (K-feldspar) alteration corridors.

The supergene zone at Star Main is a particularly noteworthy prospect for Star Copper and a relatively rare find for this area of Canada., Supergene enrichment is a geological process where valuable metals are concentrated near the Earth's surface, producing an enhanced grade of ore deposits. Hypogene mineralization involves ascending fluids from deep within the Earth. Chalcopyrite mineralization refers to the occurrence of chalcopyrite, a copper iron sulfide mineral (CuFeS2), within various geological formations and ore deposits.

Samples from the Phase 1 program have been shipped to the laboratory, and results will be reported once received and reviewed under QA/QC protocols.

The second phase of drilling plans are already underway based on Phase 1 results alongside concurrent widespread exploration work completed during the Phase 1 campaign. Field teams advanced several previously surveyed proximal targets to build a pipeline of Phase 2 opportunities. At Star North, detailed mapping plus 135 rock and 29 soil infill samples tightened structural and alteration controls; Star East saw mapping and 59 rock samples that refined interpretations of geophysical anomalies; Star West received soil-grid extensions and prospecting to broaden geochemical coverage; and at Copper Creek, new trail access, mapping, and 32 rock samples established logistically ready drill targets. Taken together, the Phase 1 work now links the Star Main porphyry system to the surrounding targets and moves Star North and Copper Creek toward drill-ready status with several clearly ranked targets.

Company CEO, Darryl Jones notes, "Our phase 1 six-hole drill program successfully confirmed copper mineralization in multiple intrusive phases, refined structural and alteration models including potassic halos and supergene enrichment, and expanded the supergene mineralized footprint at the Star Main zone up to 250m x 300m. With momentum building, Phase 2 is planned for fall 2025 and will pursue targeted step-outs and deeper tests at Star Main while adding exploratory holes at Star North and Copper Creek to expand the copper footprint and unlock new discovery potential across the property. Star Copper looks forward to sharing Phase 1 results and launching the next phase of growth at our increasingly intriguing Star Project.
