LORNE HARDER ACQUIRES ADDITIONAL 9.49% IN CASCADERO COPPER CORPORATION

November 18, 2025 - Lorne Harder, of c/o 395-901 West Third Street, North Vancouver, British Columbia, has filed an early warning report dated November 18, 2025, disclosing his recent acquisition of common shares (each, a "Common Share") in the capital of Cascadero Copper Corporation (the "Issuer") (TSX.V: CCD). This acquisition transaction did not take place in the market. The acquisition was made by Lorne Harder through his wholly-owned company, Harder Investments Ltd. ("Harder Investments").

On November 18, 2025, Harder Investments acquired an aggregate of 28,478,614 Common Shares from InCoR Holdings Limited ("InCoR") pursuant to the Court Order Enforcement Act (British Columbia) as partial satisfaction of a judgment (the "Seizure") obtained by the acquiror, Springhill Investments Ltd. and Harder Investments (collectively, the "Harder Parties") against InCoR and certain of its related parties (the "InCoR Parties").

The Seizure increased the acquiror's direct and indirect shareholdings in the Issuer to 105,100,351 Common Shares, increasing the acquiror's ownership percentage in the issued and outstanding Common Shares by 9.49% (calculated on a non-diluted basis) such that the acquiror's shareholding percentage of the issued and outstanding Common Shares is 35.02% (calculated on a non-diluted basis). Mr. Harder's acquisition of these securities triggered the requirement to file an early warning report (the "Early Warning Report").

Before the Seizure, the acquiror, including Common Shares held through Harder Investments, Springhill Investments Ltd. ("Springhill") and the acquiror's spouse (collectively, the "Harder Parties"), held 76,621,737 Common Shares, warrants to purchase 9,663,482 Common Shares at an exercise price of $0.05 per Common Share expiring on January 17, 2027, and options to purchase 2,500,000 Common Shares at an exercise price of $0.05 per Common Share expiring on February 18, 2026, representing 25.53% of the issued and outstanding Common Shares on a non-diluted basis and 28.43% of the issued and outstanding Common Shares on a partially diluted basis.

After the Seizure, the acquiror, including Common Shares held through Harder Investments, Springhill and the acquiror's spouse, holds 105,100,351 Common Shares, warrants to purchase 9,663,482 Common Shares at an exercise price of $0.05 per Common Share expiring on January 17, 2027, and options to purchase 2,500,000 Common Shares at an exercise price of $0.05 per Common Share expiring on February 18, 2026, representing 35.02% of the issued and outstanding Common Shares on a non-diluted basis and 37.55% of the issued and outstanding Common Shares on a partially diluted basis.

The Common Shares were acquired under the Court Order Enforcement Act (British Columbia) as partial satisfaction of a judgment obtained by the Harder Parties against the InCoR Parties. Mr. Harder reserves the right to formulate other plans or make other proposals and take such actions with respect to its investment holding as it may determine in its sole discretion.
