NATURE OF OPERATIONS AND GOING CONCERN [Text Block]	1. NATURE OF OPERATIONS AND GOING CONCERN Lion Copper and Gold Corp. ("LCG"), together with its subsidiaries, collectively, the "Company", is engaged in the acquisition, exploration and development of copper properties in the United States. The Company is currently advancing its flagship Yerington Copper Project in Nevada toward a Feasibility Study (the "FS"), pursuant to an earn-in agreement with Nuton LLC ("Nuton"), a Rio Tinto venture. LCG was incorporated in British Columbia, Canada on May 11, 1993. Its common shares are listed on the Canadian Securities Exchange ("CSE") under the symbol "LEO" and are quoted for trading on the OTCQB Market under the symbol "LCGMF". The Company acquires mineral properties through option agreements and claim staking. The carrying value of its mineral properties represents the acquisition costs and does not reflect present or future values. The recoverability of these assets is dependent on the discovery of mineral reserves, the Company's ability to secure sufficient financing for corporate and other obligations, and the successful development disposition of the properties. The Company's development activities on the Yerington Copper Project are substantially funded under an earn-in agreement with Nuton rather than direct Company funding. These condensed interim consolidated financial statements ("Interim Financial Statements") have been prepared on a going concern basis, which assumes the Company will continue to operate for the foreseeable future and realize its assets and discharges its liabilities in the normal course of business. As of June 30, 2026, the Company had an accumulated deficit of $126,304 (December 31, 2025 - $115,826), and working capital of $1,431 (December 31, 2025 - working capital deficiency of $3,157). The Company has not generated revenue and will require additional financing to fund general corporate and administrative activities and repay its outstanding convertible debt obligations when due. Although the Company has historically been successful in raising capital, there can be no assurance that additional financing will be available on acceptable terms, or at all. These conditions and events raise substantial doubt about the Company's ability to continue as a going concern. The Interim Financial Statements do not include any adjustments that would be necessary if the Company were unable to continue as a going concern. Such adjustments could be material.

1. NATURE OF OPERATIONS AND GOING CONCERN

Lion Copper and Gold Corp. ("LCG"), together with its subsidiaries, collectively, the "Company", is engaged in the acquisition, exploration and development of copper properties in the United States. The Company is currently advancing its flagship Yerington Copper Project in Nevada toward a Feasibility Study (the "FS"), pursuant to an earn-in agreement with Nuton LLC ("Nuton"), a Rio Tinto venture.

LCG was incorporated in British Columbia, Canada on May 11, 1993. Its common shares are listed on the Canadian Securities Exchange ("CSE") under the symbol "LEO" and are quoted for trading on the OTCQB Market under the symbol "LCGMF".

The Company acquires mineral properties through option agreements and claim staking. The carrying value of its mineral properties represents the acquisition costs and does not reflect present or future values. The recoverability of these assets is dependent on the discovery of mineral reserves, the Company's ability to secure sufficient financing for corporate and other obligations, and the successful development disposition of the properties.

The Company's development activities on the Yerington Copper Project are substantially funded under an earn-in agreement with Nuton rather than direct Company funding.

These condensed interim consolidated financial statements ("Interim Financial Statements") have been prepared on a going concern basis, which assumes the Company will continue to operate for the foreseeable future and realize its assets and discharges its liabilities in the normal course of business.

As of June 30, 2026, the Company had an accumulated deficit of $126,304 (December 31, 2025 - $115,826), and working capital of $1,431 (December 31, 2025 - working capital deficiency of $3,157).

The Company has not generated revenue and will require additional financing to fund general corporate and administrative activities and repay its outstanding convertible debt obligations when due. Although the Company has historically been successful in raising capital, there can be no assurance that additional financing will be available on acceptable terms, or at all. These conditions and events raise substantial doubt about the Company's ability to continue as a going concern.

The Interim Financial Statements do not include any adjustments that would be necessary if the Company were unable to continue as a going concern. Such adjustments could be material.
