STAR COPPER FULLY FUNDED 15,000 METRE DRILL PROGRAM TARGETS MAIDEN RESOURCE IN 2026

Star Copper Corp. is planning a fully financed, multiphase exploration program at its flagship Star project in northwestern British Columbia.

The company is advancing preparations for its 2026 drill program anticipated to encompass up to 15,000 metres focused on first pass and follow-up drilling across the Star Main and four key exploration target areas including the Star North, Copper Creek, Star East and Star West target locations.

Crews are mobilizing onsite to begin prepping the camp for the largest work program in the history of the project. The entire program is fully financed through more than $12-million in flow-through financing.

Highlights

• Drill pad construction commences at Star West, North, East and Copper Creek locations to expedite drill installation and rapid relocation to meet logistics schedule and anticipated pace of operations.
• 3-D IP and MT survey deployed to tighten geophysical modeling in preparation for testing all targets at depth.
• Drill pad locations are being situated to test satellite targets to increase overall knowledge base and refine the advancement of a nested porphyry model.

Company chief executive officer Darryl Jones notes: "With over $12-million in flow-through capital in place, we are fully funded to execute our planned objectives aimed at delivering a maiden resource estimate this year. The planned 3-D IP and MT surveys will enhance our understanding of the system at depth and significantly aid in vectoring towards the core of the porphyry system. With a multitarget drill program of this proposed scale, we are aggressively positioning Star Copper as we head into 2026. We are excited to begin systematically drilling across this intriguing range of high-value prospects offering strong potential to host Star Main-style mineralization."

Drilling will initially be focused on the Copper Creek target to follow up on last year's highly promising results from drill hole CC-25-001 which returned 57.0 metres of 0.614 per cent CuEq (copper equivalent) within 111.0 m of 0.348 per cent CuEq (see company news March 24, 2026).

The target at the Copper Creek location is a series of IP chargeability highs with elevated coincident copper and gold-in-soil anomalies. The 2025 drill program focused on the confirmation of an historic mineralized zone first discovered in the 1970s. The 2026 focus will be to vector in on the source of that mineralization with follow up drilling early in the season.

As the team mobilizes and expands drill preparations and related planning, the company aims to systematically drill additional targets to refine the overall property-wide geologic model and further test known chargeability and soil anomalies.

The Star East location is an untested target 500 m east of Star Main with a 1,000 m by 1,000 m coincidental chargeability and soil anomaly, which appears analogous to Star Main, ensuring it inclusion as a priority target for further exploration.

At the Star North location, which saw its inaugural drill hole in 2025, is another look alike target to Star Main which is located approximately 1.5 kilometres to the northeast. Extensive soil and rock sampling, mapping, and geophysics provide the Star Copper exploration team a growing sense of opportunity, especially as slightly north is a new emerging target which showed elevated copper in soils and is scheduled to be tested early in the 2026 season.

Program highlights

• 2026 drill program designed to test scale;
• Up to 15,000 metres of drilling;
• Targets: Star North, Copper Creek, Star East and Star West;
• 3-D IP and MT surveys for deeper targeting;
• Fully financed with $12-million-plus flow-through.

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.
