STAR COPPER PLANS DISCOVERY EXPANSION WORK AT STAR PROJECT

Star Copper Corp. has provided an overview of exploration and discovery expansion plans at its flagship asset, the Star project, located in the heart of the industry recognized Golden Triangle of British Columbia.

Project overview

The Star project spans 6,829 hectares and is 100 per cent owned by Star Copper. The property is fully permitted under a multiyear area-based (MYAB) notice of work, enabling near-term and future exploration. Situated in a Tier 1 jurisdiction, the Star project boasts over $10-million in historical exploration work, including geophysical and geochemical surveys, trenching, soil sampling, and more than 13,000 metres of drilling from 49 diamond drill holes, confirming the presence of a calc-alkalic porphyry copper-gold system.

Darryl Jones, Star Copper's chief executive officer, commented: "Having sat idle for years, the Star project is one of Canada's best-kept secrets. Given the massive historical data set, stellar drilling results, proven copper discovery and significant attractive analogous look-alike porphyries on the property, we are yet to identify another project throughout the entire region with as much potential as found at the Star project. Our dedicated team is committed to defining the scope and scale of the existing discovery, in addition to making additional discoveries on the nearby look-alike showings."

Previous discovery -- Star Main

Historic drilling at the Star Main zone has confirmed a robust mineralized system open in all directions, including at depth. The Star project exhibits classic porphyry-style alteration and mineralization over a broad area. The Star Main target has a preserved supergene oxide zone at surface, which is confirmed by several high-grade intercepts (see Table 1 below). The surface oxidized zone above the primary sulphide mineralization is dominated by malachite and azurite with local native copper, chalcocite and tenorite.

Mineralization was intersected in several holes enlarging the known high-grade secondary material. Known mineralization has shown a steeply dipping pipe but the centre or bornite zone has not been encountered. The Star Main target holds immense potential to grow laterally and at depth and the company intends to test those in the proposed coming field program.

The long intercepts, shown above, demonstrate the continuity and scale of copper-gold mineralization within the Star Main zone.

High-impact discovery targets -- Star North and Star East

In addition to the Star Main discovery, the Star North and Star East areas of mineralization exhibit all the same geological characteristics with large geochemical and geophysical signatures, positioning the company for a robust year of work ahead.

Star North

Located approximately one kilometre northeast of Star Main, Star North is a large, undrilled porphyry target. It features a 500-metre-by-700-metre-wide zone of strong IP (induced polarization) chargeability, magnetic anomalies and multielement soil enrichment (copper, gold, silver, molybdenum, zinc and lead). The geological setting closely mirrors that of Star Main, with similar structural features and alteration. Star North represents a rare, near-surface opportunity to uncover a new copper-gold system immediately adjacent to a known deposit.

Star East

Positioned roughly one kilometre east-southeast of Star Main, Star East covers a 500-metre-by-500-metre-wide anomaly defined by IP chargeability and multielement soil geochemistry. Surface trenching has confirmed mineralization, yet the area remains entirely untested by drilling and is open in all directions. With geophysical and geochemical signatures consistent with Star Main, Star East is viewed as a top-tier drill-ready target with significant expansion potential.

Strategic outlook

Star North and Star East are considered two of the most compelling greenfield discovery targets on the property. Their proximity to Star Main, coupled with strong technical signatures and a lack of historical drilling, presents a unique opportunity for significant new discoveries within one of Canada's most productive mining regions.

Star Copper's exploration strategy is focused on:

• Expanding and deepening the existing Star Main zone;
• Testing high-potential targets across the Star North and Star East areas of interest.

This multipronged approach is designed to unlock the broader district-scale potential of the Star project and positions Star Copper as a leading copper-gold explorer in the Golden Triangle region.

The company anticipates mobilizing drilling equipment and crews to the Star project in the coming days and looks forward to providing regular progress updates over the coming weeks ahead.
