Star Copper Mobilizes 2025 Summer Exploration Targeting Expansion of Existing Discovery

Rhea-AI Summary

Star Copper Corp (STCUF) has initiated its 2025 summer exploration program at its flagship Star Project in British Columbia's Golden Triangle. The $2.5 million fully-funded campaign will run until August 15, 2025, featuring a 3,500-metre diamond drill core sampling program across six drill holes. The Star Project, spanning 6,829 hectares and 100% owned by Star Copper, has seen over $10 million in historical exploration, including 13,000 meters of drilling from 49 diamond drill holes. The program aims to expand the known mineralized envelope, test deeper porphyry potential, and follow up on mineralization near the Star Fault. Historical drilling has shown promising results, with intercepts including 200m @ 0.49% Cu and 0.24 g/t Au. The campaign will utilize integrated 3D inversion modeling of airborne magnetic data to guide drilling strategy.

Positive

• Project is fully funded with $2.5 million allocated for exploration
• Property is 100% owned by Star Copper with full permits under MYAB Notice of Work
• Historical drilling shows significant copper-gold mineralization (e.g., 200m @ 0.49% Cu, 0.24 g/t Au)
• Located in the prolific Golden Triangle region with $10 million in historical exploration

Negative

• Property has remained unexplored for over a decade
• Previous drill holes limited to 660m depth, potentially limiting deep exploration

Company set to build asset value in prolific "Golden Triangle"

VANCOUVER, BC / ACCESS Newswire / May 27, 2025 / Star Copper Corp. (CSE:STCU)(OTC PINK:STCUF)(FWB:SOP) ("Star Copper" or the "Company"), a Canadian resource exploration and development company, is pleased to announce that equipment and crew have been mobilized to shortly commence drilling and other exploration activities in the field. Today's news officially kicks off Star Copper's 2025 drill plans at its flagship asset, the Star Project, located in the heart of the prolific industry recognized "Golden Triangle" of northwestern British Columbia.

The Star Project spans 6,829 hectares and is 100% owned by Star Copper. The property, and this current exploration program, are fully permitted under a Multi-Year Area-Based (MYAB) Notice of Work, enabling current and future exploration. Situated in a tier-one jurisdiction, the project boasts over $10 million in historical exploration efforts, including geophysical and geochemical surveys, trenching, soil sampling, and more than 13,000 meters of drilling from 49 diamond drill holes, which have confirmed the presence of a calc-alkalic porphyry copper-gold system.

The campaign builds upon a significant historical exploration database and incorporates newly reinterpreted magnetic data to guide the next phase of high-impact drilling. Additionally, the Company will be looking to test the contiguous Star North and Star East claims through targeted sampling and trenching to confirm the geotechnical work which indicates similar characteristics to the Star Main deposit.

Darryl Jones, Star Copper's CEO, comments, "Embarking on our maiden program at Star is an exciting time for our shareholders, as this property has remained amazingly untouched in more than a decade. Our team's efforts to-date lead us to believe that the Star Project holds significant potential based on the inherent mineralization characteristics and geological trend data evident throughout the property. We are very eager to advance the Star North and East projects to further deliver potentially new discoveries aimed at unlocking the true value of the Star Project for our company, stakeholders, and shareholders alike."

2025 Exploration Overview
The fully funded $2.5 million campaign is scheduled to run until August 15, 2025, and incorporates a strategic plan already underway with the field crew currently moving to build a base camp supported by full onsite logistical capabilities. Once established, the team will situate new drill pads to undertake a 3,500-metre diamond drill core sampling program based on six drill holes with an additional 650 metres of contingency drilling allocated.

Key program objectives include:

• Expanding the known mineralized envelope of the Star Main zone

• Testing deeper porphyry potential and structural offsets

• Following up on mineralization associated with the recently modeled Star Fault

Drill Targeting Basis
The program will utilize integrated 3D inversion modeling of 2013 airborne magnetic data, which was completed by Ronacher MacKenzie Geoscience. The new geophysical interpretation, along with trench mapping and core analysis, has confirmed a complex left-lateral strike-slip system and defined key structural features identified as:

• The Star Fault: A mineralized thrust-related structure that segments higher-grade mineralization in the northeast and offsets deeper mineralization to the southwest.

• The Dick Creek Fault and Hackett Valley Fault: Large-scale regional fault corridors that outline the structural controls of mineral emplacement.

The refined modeling is being used to position drill holes to test both near-surface and deep mineralization, including areas previously untested by drilling.

Selected Drill Targets for 2025
The planned holes include follow-ups on the following successful historical intercepts:

• Hole S025: 200m @ 0.49% Cu, 0.24 g/t Au

• Hole S027: 263m @ 0.39% Cu, 0.12 g/t Au

• Hole S029: 81m @ 0.35% Cu, 0.18 g/t Au

• Hole S040: 120m @ 0.36% Cu, 0.13 g/t Au

• Hole S023: 100m @ 0.47% Cu, 0.19 g/t Au

Please refer to the Company's February 26, 2025 technical report on the Star Project for more information in respect of the project, including historical drilling, available under the Company's profile at www.sedarplus.ca.

Once constructed, the new drill pads will also test untested magnetic anomalies, soil geochemical highs, and deep extensions of chargeability zones with the goal of expanding the known deposit at Star, both laterally as well to depth. Drill holes have not exceeded 660m in previous programs but the mineralization down hole shows the potential for much deeper targeting. The extensive supergene zone discovered at surface is exceptionally rare and the Company is excited to enhance the historic drilling with its own program this summer.
