Lion Copper and Gold Corp. Receives US$30.5 Million from Nuton to Advance Yerington Copper Project

Vancouver, British Columbia--(Newsfile Corp. - January 26, 2026) - Lion Copper and Gold Corp. (CSE: LEO) (OTCQB: LCGMF) ("Lion CG" or the "Company") is pleased to announce that it has received US$30.5 million from Nuton LLC ("Nuton"), a wholly-owned subsidiary of Rio Tinto, further to the Company's press release dated November 24, 2025, pursuant to the parties' previously announced earn-in agreement relating to the advancement of the Yerington Copper Project in Nevada, USA.

The funding represents Nuton's investment under Stage 3 of the earn-in framework and will be used to advance the Definitive Feasibility Study (DFS) and associated permitting activities, including technical optimization, engineering, environmental studies, and regulatory engagement.

"This investment represents a major execution milestone for Lion CG and further validates the scale, quality and strategic importance of the Yerington Copper Project," said John Banning, Chief Executive Officer of Lion CG. "This substantial partner funding enables the Company to advance the DFS and permitting work without significant dilution and execution risk for Lion CG shareholders."

The Yerington Copper Project is located in a Tier-1 U.S. jurisdiction and has the potential, subject to the outcomes of ongoing studies and permitting, to contribute to the domestic production of copper cathode. Establishing additional U.S.-based copper cathode supply is increasingly viewed as strategically important given rising demand from electrification, grid modernization, electric vehicles, and data center infrastructure, and ongoing efforts to strengthen domestic critical mineral supply chains.

Lion CG intends to progress the Yerington Copper Project toward qualification under the U.S. federal FAST-41 permitting framework, which is designed to enhance transparency, coordination, and predictability in the federal permitting process for major infrastructure and critical mineral projects.

As part of the DFS work program, the Nuton® Technology is expected to be further refined, with the objective of improving copper recoveries and potentially reducing capital intensity and environmental footprint relative to conventional processing routes.

Lion CG remains focused on disciplined project advancement, capital stewardship, and long-term value creation as it advances Yerington toward potential development in support of secure, domestic copper supply.
