Star Copper Concludes Drill Season with Robust Stability Sheet and Momentum into 2026

Firm closes each LIFE and Movement By Personal Placements

VANCOUVER, BC / ACCESS Newswire / December 9, 2025 / Star Copper Corp. (CSE:STCU)(OTCQX:STCUF)(FWB:SOP) (“Star Copper” or the “Firm”), a vital minerals exploration and growth firm is happy to supply a year-end abstract of actions and accomplishments along with steering relating to expectations for the 2026 exploration season.

Highlights

• Increase of over $17 MM

• Drilled 4900m in 2 phases, examined 2 new targets

• 11 holes nonetheless pending at assay labs

• First 3 holes launched (see Part 1 Highlights)

• Allow prolonged to 2028

• Work camp and airstrip remediation accomplished

Achievements in 2025 had been initially based mostly upon in depth data representing $10 million in historic drilling. The just lately concluded marketing campaign efficiently examined each the lateral and vertical continuity of beforehand recognized mineralized zones together with in depth area-wide area work together with mapping, soil and rock sampling. The mixed outcomes considerably lengthen total geochemical and geophysical data and supply necessary steering for the upcoming 2026 season.

Firm CEO, Daryl Jones notes, “Constructing off robust fundamentals, we raised over $17 million to fund a transparent set of exploration targets. Our technical workforce successfully reprocessed present geophysical knowledge to provide 3D magnetic inversion fashions, which produced a nested porphyry mannequin, which in flip guided 4,900 meters of focused drilling throughout two preplanned phases. A complete of 13 holes had been drilled, which expanded the Star Primary supergene oxidized deposit to roughly 500 meters x 550 meters x 100 meters deep, demonstrated a constant transition from supergene to hypogene mineralization under 200 meters, verified that mineralization continues to be open under depths of no less than 500 meters, and maybe most significantly, considerably expanded the recognized areas of mineralization in a number of instructions as much as 2.5 kilometers from the Star Primary asset onwards to our Copper Creek and Star North mission areas. The Firm then capped off 2025 with one other progressive financing which positions the Firm to exit 2025 with practically $10 million in money on the steadiness sheet. All this exercise packed into one exploration season actually units the stage for an thrilling 12 months forward.”

“Trying ahead to 2026,” Jones continues, “the Firm is planning on strengthening and delineating present Star asset fashions with detailed 3D geophysical knowledge research to supply higher, and extra correct complete evaluation with the incorporation of all assay outcomes together with from pending assays from as-yet unreported holes drilled in 2025, and by attracting specialised technical and operational expertise to extend and enhance our capacity to successfully handle the expansion centered scope of the mission.”

Part 1 Drill Marketing campaign Abstract (to-date)

Part 1 drilling expanded the near-surface supergene footprint to the west and southwest, confirmed copper mineralization throughout a number of intrusive phases, and sharpened the structural and alteration framework-particularly alongside the Star Fault and related potassic (Ok-feldspar) alteration corridors. The six-hole drill marketing campaign (S-050, S-051, S-052, S-053B, S-054A, S-055) totaled over 2200m and culminated with Gap S-055 (2025-E), which intersected a near-surface oxide horizon (seen malachite and azurite) transitioning at depth to chalcopyrite in mineralized quartz monzodiorite, in line with our oxide-to-hypogene mannequin alongside main constructions. With assay outcomes nonetheless pending, the Firm will take the winter months to refine the geologic mannequin to additional advance future drilling on Star. Assays outcomes for the preliminary three drillholes have been accomplished (see information releases September 22, 2025, and September 30, 2025), with assays pending for holes S-503B, S-054A, and S-055.

Highlights from Part 1

• Gap S-051 intersected 226.54m 0.70% CuEq (0.44% Cu & 0.25 g/t Au) from 14m.

• Gap S-050 intersected 93m 0.93% CuEq (0.56% Cu & 0.36 g/t Au) from 8m.

• Gap S-052 intersected 397m of 0.37% CuEq (0.25% Cu & 0.11 g/t Au) from 29m.

Samples from the Part 1 program have all been shipped to the laboratory, and outcomes can be reported as soon as acquired and reviewed underneath our QA/QC protocols. The supergene zone continues to ship essentially the most thrilling early visuals, giving confidence that this might be a probably massive oxide footprint (See inset picture Figures 2 & 3). With the Star mission holding huge potential within the supergene zone, the Firm is extraordinarily excited in regards to the hypogene mineralization which continues northwest and southeast of the supergene with a footprint of 1 km lengthy by 500 m broad. The hypogene system additionally extends nicely under the 100m depth to nicely over 400m as reported within the first 3 holes from Part 1.

Part 2 Drill Marketing campaign Abstract (thus far)

Part 2 wrapped up mid-November with a complete of two,700 m unfold over the Star Primary deposit, Star North and Copper Creek targets. The drilling was profitable in confirming that each Star North and Copper Creek confirmed precious seen chalcopyrite and robust mineralization that can be adopted up in 2026 drilling (see Determine 5).

Star Primary drilling in Part 2 centered across the relationship between supergene to hypogene transition and the constructions that carry the mineralization. Copper Creek is a traditionally drilled goal 2.2 km Southeast of the Star Primary deposit and has a really robust soil signature related to a coincident chargeability excessive just like Star Primary. One gap was drilled to a depth of 120 m and intersected robust VMS mineralization over a broad intercept on the goal depth. Star North, which is one other robust soil anomaly and coincidental chargeability excessive, positioned 1 km northeast of the Star Primary noticed 400m of drilling to check the construction to permit for additional drilling to broaden the goal in 2026. Star Primary additionally noticed extra comply with up drilling throughout section 2 to substantiate the hypogene mineralization and broaden the general deposit mannequin. A complete of 13 holes had been drilled at Star Primary with 11 assays nonetheless pending.

In Conclusion

The Firm is now compiling all related work accomplished within the area in 2025 to raised perceive the deposit mannequin on Star Primary and develop the mannequin for Star North and Copper Creek. With a really profitable 2025 drill season concluded, the Firm is tremendously excited in regards to the prospects for the 2026 marketing campaign. The Firm seems to be ahead to commencing fieldwork early in 2026 to undertake extra drilling, extra 3D geophysics and associated knowledge compilation to proceed rising our price proposition to fulfill the expectations of our workforce members, stakeholders and shareholders as we try in the direction of affirming Star Copper holds Canada’s subsequent huge copper deposit.

Key takeaways

• Sturdy deposit mannequin displaying transition from supergene to hypogene intact

• Mineralization continues to 500m, and open at depth

• Sturdy drill goal pipeline for 2026 area work

• Deep 3D geophysical modelling deliberate to reinforce deposit mannequin

• Assays nonetheless pending for 11 holes

• Effectively-funded to open camp and start 2026 area season
