(via TheNewswire)

Vancouver, British Columbia - May 29, 2026 – TheNewswire - Cascade Copper Corp. (CSE: “CASC”; FRA:”91O” ) (“ Cascade ” or the “ Company ”) is pleased to announce that it has closed the first tranche of its previously announced non-brokered private placement of units (the “ Units ”) for aggregate gross proceeds in this tranche of CDN$352,444.92 (the “ Offering ”). The Company has received strong interest in the Offering and expects to close a second tranche in the coming weeks.

The first tranche of the Offering consisted of the issuance of an aggregate of 1,286,000 critical mineral flow-through units (the “FT Units”) at a price of $0.07 per FT Unit, and 4,771,362 non-flow-through units (the “NFT Units”) at a price of $0.055 per NFT Unit.

Each FT Unit consists of one common share issued as a “flow-through share” within the meaning of subsection 66(15) of the Income Tax Act (Canada) (a “FT Share”) and one-half of one non-flow-through common share purchase warrant. Each NFT Unit consists of one common share (a “NFT Share”) and one-half of one common share purchase warrant. Each whole warrant is exercisable to acquire one common share of the Company at an exercise price of $0.10 for a period of 36 months from the closing date of the Offering (collectively, the “Warrants”).

The Offering remains subject to all necessary regulatory approvals, including acceptance by the Canadian Securities Exchange (the “CSE”). All securities issued in connection with the Offering will be subject to a four-month hold period from the applicable closing date under applicable Canadian securities laws, in addition to such other restrictions as may apply under applicable securities laws of jurisdictions outside Canada. The Offering is being made by way of private placement in Canada and such other jurisdictions as the Company may determine. Following completion of this first tranche, the Company has 70,921,859 common shares issued and outstanding.

Subscribers in the Offering included certain insiders of the Company (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 exemptions from the formal valuation requirement and minority shareholder approval requirement under subsections 5.5(a) and 5.7(1)(a) of MI 61-101, respectively, in respect of the Insider participation in the Offering, as the fair market value of the Units subscribed for by the Insiders does 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 will be used to incur eligible “Canadian exploration expenses” that are intended to qualify as “flow-through critical mineral mining expenditures”, each as defined in the Income Tax Act (Canada) (the “Qualifying Expenditures”). The Qualifying Expenditures will be used primarily to fund drilling and exploration at the Company’s critical minerals projects in British Columbia and Ontario. The gross proceeds from the sale of the NFT Units will be used for general corporate and working capital purposes.

The Company intends to renounce the Qualifying Expenditures to subscribers of the FT Units with an effective date no later than December 31, 2026, and to incur the Qualifying Expenditures on or before December 31, 2027, in accordance with the requirements of the Income Tax Act (Canada).

In connection with the Offering, the Company paid aggregate cash commissions of CDN$4,334.00 to one arm’s length finder and issued 78,800 finder warrants (the “Finder Warrants”). Each Finder Warrant is exercisable to acquire one common share of the Company at an exercise price of $0.055 for a period of 24 months from the closing date of the Offering.

The Existing Shareholder Exemption and Investment Dealer Exemption

The Offering was made available to existing shareholders of the Company who, as of the close of business on May 27, 2026, held common shares of the Company and continued to hold such common shares as of the closing date, pursuant to the prospectus exemption set out in B.C. Instrument 45-534 - Exemption From Prospectus Requirement for Certain Trades to Existing Security Holders and similar instruments in other jurisdictions of Canada. The existing shareholder exemption limits a shareholder to a maximum investment of $15,000 in a 12-month period unless the shareholder has obtained advice regarding the suitability of the investment and, if the shareholder is resident in a jurisdiction of Canada, such advice has been obtained from a person registered as an investment dealer in that jurisdiction. If the Company receives subscriptions from investors relying on the existing shareholder exemption that exceed the maximum amount of the Offering, the Company intends to adjust such subscriptions on a pro rata basis.

The Company has also made the Offering available to certain subscribers pursuant to B.C. Instrument 45-536 - Exemption From Prospectus Requirement for Certain Distributions Through an Investment Dealer. In accordance with the requirements of the investment dealer exemption, the Company confirms that there is no material fact or material change about the Company that has not been generally disclosed.
