LION COPPER CORP. COMPLETES S-K 1300 TECHNICAL REPORT SUMMARY FOR BEAR COPPER DEPOSIT

Lion Copper Corp. has completed its technical report summary (TRS) for the company's Bear copper deposit, located within the Yerington copper (Cu) district in Lyon county, Nevada.

The TRS was prepared in accordance with Subpart 1300 of Regulation S-K (S-K 1300), the mineral property disclosure requirements of the U.S. Securities and Exchange Commission (SEC), and supports the previously announced Bear mineral resource estimate (MRE). It follows the company's filing of the National Instrument 43-101 technical report on Sept. 14, 2026.

The Bear MRE, previously announced on Aug. 4, 2026, comprises an indicated mineral resource of 6.71 billion pounds of contained copper (1,064 million tonnes grading 0.29 per cent Cu) and an inferred mineral resource of 8.77 billion pounds of contained copper (1,770 million tonnes grading 0.22 per cent Cu).

John Banning, chief executive officer of Lion Copper, commented:

"The completion of the S-K 1300 technical report summary for Bear represents another important milestone for Lion, providing the technical foundation for disclosing this substantial copper resource under U.S. reporting standards.

"With an indicated resource of 6.71 billion pounds of copper and an inferred resource of 8.77 billion pounds of copper, Bear significantly expands our copper resource base and reinforces the long-term development potential of the Yerington copper district.

"Our immediate priority remains advancing the Yerington copper project through a definitive feasibility study and permitting, with completion and publication of the DFS targeted for the first quarter of 2027. Bear provides additional longer-term development opportunities, including the potential to leverage infrastructure contemplated for Yerington."

Bear mineral resource estimate

The Bear deposit is contiguous with Lion's Yerington copper project in Lyon county's Mason Valley in Nevada and represents a substantial additional copper resource within the company's broader district-scale development strategy.

The S-K 1300 TRS provides supporting geological, drilling and mineral resource estimation information, including the assumptions underlying the determination of reasonable prospects for economic extraction.

Lion is advancing the Yerington copper project through a definitive feasibility study and permitting, supported by its strategic partnership with Nuton LLC, a Rio Tinto venture. The potential for Bear to use infrastructure planned for Yerington is subject to further technical evaluation and depends on the availability and suitability of that infrastructure.

S-K 1300 technical report summary

The completion of the Bear S-K 1300 TRS provides technical documentation prepared in accordance with the SEC's mineral property disclosure requirements applicable to U.S. reporting companies.

The TRS complements the previously filed NI 43-101 technical report and supports the company's disclosure of the Bear mineral resource under applicable U.S. reporting standards.

The TRS is available on EDGAR as exhibit 96.1 to the company's Form 10-Q for the quarter ended Sept. 30, 2026.
