STAR COPPER MULTI TARGET DRILL PAD CONSTRUCTION UNDERWAY IN PREPARATION FOR 15,000 METRE DRILL PROGRAM

Star Copper Corp. drill pad construction has commenced across multiple high-priority satellite targets at its northwestern British Columbia flagship Star project in preparation for a fully financed 2026 exploration program.

Company chief executive officer Darryl Jones advises: "We are very encouraged to receive confirmation regarding the advancement of drill pad construction aimed at expediting a systematic drill strategy focused on our Star North, Star East, Star West and Copper Creek project locations. The construction effectively heralds the launch of the largest and most co-ordinated exploration effort in the project's history.

"The heightened degree of co-ordinated infrastructure development allows us to systematically test a pipeline of targets that all exhibit key characteristics of Star Main-style mineralization," added Mr. Jones. "Importantly, it positions us to move quickly to follow up on results in real time and fully evaluate the district-scale potential of the Star project as we advance toward a maiden resource."

Transition to district-scale discovery

Near simultaneous construction at four target locations is primarily designed to support efficient and flexible drill testing throughout the 2026 field season. Each pad location has been strategically selected based on integrated geological, geochemical and geophysical data sets, including coincident chargeability anomalies and copper-gold soil geochemistry.

This infrastructure development represents a key milestone in transitioning the Star project from single-target exploration to a district-scale discovery strategy, enabling:

• Systematic drill testing across multiple targets early in the 2026 season;
• Rapid follow-up on mineralization to test nested porphyry model;
• Improved access to structurally complex zones.

Target highlights

Copper Creek

Initial pad construction is most advanced at Copper Creek, where drilling will begin early in the season to follow up on prior mineralization and vector toward the source of copper-gold enrichment. Drilling in 2025 centred on locating the historic drill collars to target the exposed copper mineralization. With that confirmed in 2025, the goal this year is to effectively test the geophysical signature associated with the chargeability to confirm the source. Copper Creek is the most advanced target behind Star Main, which gives the company immense confidence early in the season to deliver and test the existence of a nested porphyry model at the Star project.

Star North

Drill pads are being constructed to expand on previous drilling and test a large, well-defined geophysical and geochemical footprint, supporting stepout drilling to evaluate scale and continuity. The northern side of the target has shown significant surface expressions of copper oxide mineralization and a coincidental chargeability signature that warrants follow up with drilling in the early season.

Star East

A first-pass drill program is being enabled at this untested target, characterized by an approximately one-kilometre-by-one-kilometre coincident anomaly analogous to Star Main, representing a compelling discovery opportunity. Star East is a target that holds promise with a geophysical signature similar to Star Main but is covered with little exposure at surface.

Star West

This target is centred on outcropping on the slope and extensive soil sampling showing elevated copper in gold with another coincidental geophysical high.

2026 program overview:

• Up to 15,000 metres of drilling;
• Targets: Star North, Copper Creek, Star East and Star West;
• 3-D IP (induced polarization) and MT (magnetotelluric) surveys to refine deeper targeting;
• Fully financed with over $12-million in flow-through financing;
• Maiden resource targeted in 2026.

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.
