CASCADE COPPER CLOSES FINANCING

Vancouver, British Columbia – October 8, 2025. Cascade Copper Corp. (CSE: “CASC”) (“Cascade” or the “Company”) is pleased to announce that it has fully closed the previously announced non-brokered private placement of units (“Units”), for aggregate gross proceeds of $401,255. The offering closed in three tranches.

The Offering consisted of the issuance of an aggregate of 2,875,000 Critical Minerals FT Units (the “FT Unit”) at a price of $0.04 per FT Unit and 8,178,713 Non-Flow-Through Units (the “NFT Units”) at a price of $0.035 per NFT Unit. Each FT Unit and NFT Unit is comprised of one common share and one-half common share purchase warrant (the “Warrant”). Each full Warrant is exercisable into a common share at a price of $0.07 for a period of 24 months from the closing of each of the tranches of the Offering (the “Closing Date”).

The Offering was subject to all necessary regulatory approvals, including acceptance from the Canadian Securities Exchange. All securities issued in connection with the Offering are subject to a four-month hold period from the closing date under applicable Canadian securities laws, in addition to such other restrictions as may apply under applicable securities laws of jurisdictions outside Canada. Upon closing of this placement, the Company will have 47,172,001 shares issued and outstanding.

Subscribers in the Offering included insider participation (the “Insiders”). The issuance of Units to the Insiders constitutes a related party transaction within the meaning of Multilateral Instrument 61-101 – Protection of Minority Securityholders in Special Transactions (“MI 61-101”). The Company is relying on the exemption from the valuation requirement and minority approval pursuant to subsection 5.5(a) and 5.7(1)(a) of MI 61-101, respectively, for the Insiders participation in the Offering, as the value of the Units subscribed for do not represent more than 25% of the Company’s market capitalization, as determined in accordance with MI 61-101.

The gross proceeds from the sale of the FT Shares, which will qualify as a “flow-through share” (as defined in subsection 66(15) of the Income Tax Act (Canada)), will be used primarily to incur eligible Critical Mineral Canadian Exploration Expenses and will be used primarily to fund exploration programs at the Company’s Projects in Ontario and British Columbia. The proceeds from the sale of the Non-Flow-Through shares will be used for the general working capital of the Company.

The Company intends to renounce the Qualifying Expenditures to subscribers of Flow-Through Units for the fiscal year ending December 31, 2025, and to incur the necessary Qualifying Expenditures on or before December 31, 2026, in accordance with regulatory requirements.
