Item 3.02 Unregistered Sales of Equity Securities

On April 17, 2026, of Idaho Copper Corporation, a Nevada corporation (the “Company”) closed a private offering (the “Offering”) of convertible promissory notes (the “Notes”) and warrants (the “Warrants”). Each Note is convertible into shares of the Company’s common stock (the “Conversion Shares”) at an initial conversion price of $6.00 per share, subject to customary anti-dilution adjustments, including adjustments in connection with subsequent issuances of securities at a price below the then-effective conversion price. The Notes have a term of twelve (12) months and will not bear interest unless an event of default occurs, at which time interest will accrue at a rate of 18% per annum. The Notes provide for voluntary conversion at any time prior to maturity. Upon a listing of the Company’s common stock on a national securities exchange in connection with a firm commitment underwritten offering, outstanding Notes will automatically convert to common stock at a conversion price equal to the lower of (i) 70% of the offering price in such transaction or (ii) $6.00, in each case subject to adjustment.

In connection with the Offering, each investor also received Warrants to purchase shares of common stock (the “Warrant Shares”), with the number of Warrant Shares equal to the principal amount of the Notes purchased divided by $6.00. The Warrants have an exercise price of $7.50 per share, subject to adjustment, and a term of five (5) years.

A total of $1,357,947 in principal amount of Notes was issued in the Offering, together with Warrants to purchase up to 226,332 shares of common stock. Each investor in the Offering entered into a Subscription Agreement with the Company, the form of which is filed herewith as Exhibit 10.1. All investors paid cash consideration with the exception of two investors, who converted existing notes in the total outstanding amount of $102,947 into Notes and Warrants issued in the Offering on a dollar-for-dollar basis, with no discount applied to the outstanding indebtedness.

The issuance of the Notes and Warrants were, and upon conversion of the Notes and exercise of the Warrants, the issuance of the Conversion Shares and Warrant Shares will be, exempt from registration under Section 4(a)(2) under the Securities Act of 1933, as amended (the “Securities Act”) and Rule 506(b) of Regulation D promulgated thereunder. The Notes and the Warrants were offered and sold exclusively to “accredited investors” as defined in Rule 501(a) under Regulation D and the Company engaged in no general solicitation or advertising in connection with the Offering. At the time of their issuance, the Notes and the Warrants were deemed to be restricted securities for purpose of the Securities Act and will bear restrictive legends to that effect.

In connection with the Offering, the Company engaged ThinkEquity LLC (“ThinkEquity”) as exclusive placement agent. In consideration for ThinkEquity’s services as placement agent, the Company paid customary placement agent fees and agreed to issue warrants to purchase shares of the Company’s common stock. The placement agent’s warrants are exercisable for a number of shares of common stock equal to 10% of the number of shares issuable upon conversion of the Notes issued in the Offering and feature the terms of which are consistent with market practice and as set forth in the applicable engagement agreement.

The foregoing descriptions of the Subscription Agreement, Note and Warrant are not complete and are qualified in their entirety by reference to the full text of the forms of the Subscription Agreement, Note and Warrant, copies of which are attached hereto as Exhibits 10.1, 10.2 and 4.1, respectively, and incorporated herein by reference.
