Arizona Tribune - Star Copper Commences Drill Campaign in BC's Golden Triangle

VANCOUVER, BC / ACCESS Newswire / June 10, 2025 / Star Copper Corp. (CSE:STCU)(OTCQB:STCUF)(FWB:SOP) ("Star Copper" or the "Company"), a critical mineral exploration and development company, is pleased to announce commencement of the 2025 drill program at its 6,829-hectare (~16,875 acre) at its flagship Star Project in British Columbia. Drilling will focus on expanding the existing discovery at Star Main, and may expand to Star North or Star East, should the current field sampling in either of those prospects warrant it.

The Star Project, located in British Columbia's "Golden Triangle" is 100% owned, 100% funded, and fully permitted. The drill campaign has recently been upsized (see June 3^rd press release). The $2.5 million program now plans over 4,000 meters of diamond drilling, builds on over $10 million of previous exploration progress, and is guided by detailed 3D magnetic inversion models and a refined structural interpretation.

New drill pads have been constructed at the Star Main discovery (Figure 1, below) and equipment can be mobilized between drill pads via existing roads and trails over manageable terrain and does not require helicopter support, which dramatically decreased the budget of the entire campaign. The drill equipment arrived on site and was prepared for immediate operation.

As described in a news release on May 27, 2025, the current drill plan is designed to test both the lateral and vertical continuity of mineralized zones previously identified with over $10 million in prior drilling and exploration campaigns, as well as newly modelled magnetic and chargeability anomalies. The 2025 plan targets both the near-surface oxide zones, deep porphyry-style mineralization, and structures associated with the "Star Fault" and "Dick Creek Fault" with up to 4,000 meters amongst six primary drill holes (Holes A-F).

Key Drill Targets:

• Hole A (Underway): A 500-meter step-out hole designed to intersect the Star Fault and test 150 meters of footwall mineralization beneath a previous intercept that yielded 200m @ (28-228m) 0.49% Cu, 0.24 g/t Au.

• Hole B: Follows up shallow oxide and sulfide mineralization north of the main zone. Nearby holes S_029 include 131m (11-130m) @ 0.41% Cu, 0.26 g/t Au.

• Hole C: A 600-meter hole intended to test deep extensions beneath S_027 (263m (7-267m) @ 0.39% Cu, 0.12 g/t Au), targeting a magnetic anomaly shell.

• Hole D: A planned 800-meter hole on the western flank, designed to extend and continue mineralization beneath S_040 (120m (352-472m) @ 0.36% Cu, 0.13 g/t Au).

• Hole E: Targeting both hanging wall and footwall zones around S_023 (290m (3 - 293m) @ 0.41% Cu, 0.19 g/t Au).

• Hole F: A planned exploratory 300-meter hole in the southwestern extension of the magnetic anomaly.

"We're leveraging the best available science and our prior drilling success to execute a strategic, high- impact drill program," said Jeremy Hanson. "This is our most technically refined drill campaign at the Star Project, to-date, and we expect it will yield strong advancements toward a mineral resource."

Darryl Jones, Star Copper's CEO, adds, "The previous drilling on the property really motivated us to advance our exploration efforts. The confirmed presence of an extensive calc-alkalic porphyry copper-gold system comes as a result of 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. This historic work, along with our newly reinterpreted magnetic data is guiding our drill targeting and also led us to begin testing the contiguous Star North and Star East claims. Given their similar characteristics to Star Main deposit, we are very keen to if the results from targeted sampling and trenching will confirm the geotechnical work. If the results prove positive, we may have a very interesting extension to the overall area of interest."

The entire drill program is supported by a reinterpretation of historic magnetic survey data inverted in early 2023 by Ronacher MacKenzie Geoscience (RMG). The resulting 3D models confirmed the presence of magnetic shells coinciding with known mineralization and identified significant structural features, including the Star and Dick Creek faults. These structures are interpreted as part of a left-lateral strike-slip regime, with thrust and R'-style fault segments acting as conduits for mineralized fluids.
