/Not for distribution to United States newswire services or for dissemination in the United States/

NorthWest Copper ("NorthWest" or the "Company") (TSX-V: NWST) is pleased to announce that it has entered into an agreement with Stifel Nicolaus Canada Inc. ("Stifel Canada"), to act as sole bookrunner and co-lead agent with Canaccord Genuity Corp. (together with Stifel Canada, the "Agents") in connection with a "best efforts" private placement offering by the Company for aggregate proceeds of up to $10 million (the "Offering").

The Offering will consist of the following securities ("Offered Securities"):

• Hard dollar units (the "HD Units") will be sold at a price of $0.35 per HD Unit,
• Charity flow-through units (the "CFT Units") will be sold at a price of $0.515 per CFT Unit, and
• Flow-through shares (the "FT Shares") will be sold at a price of $0.41 per FT Share.

The total number of HD Units, CFT Units and FT Shares will be determined by the Agent based on investor demand. Each HD Unit and CFT Unit will consist of one common share ("Common Share") of the Company and one-half of one Common Share purchase warrant (each whole warrant, a "Warrant"). Each Warrant entitles the holder to purchase one Common Share at an exercise price of 0.45 for a period of 24 months following closing of the Offering.

The Corporation has granted the Agents an option to sell up to an additional 15% of the aggregate amount of the Offered Securities (the "Agents' Option"), on the same terms and conditions of the Offering. The Agents' Option will be exercisable, in whole or in part to offer additional Hard Dollar Units, FT Shares or Charity FT Units in any combination, at any time up until 48 hours prior to the closing of the Offering.

The net proceeds from the Offering will be used to complete an updated Preliminary Economic Assessment on the Company's Kwanika-Stardust project, to advance exploration at Kwanika, to conduct surface work at the Company's Lorraine project, to advance other exploration projects held by the Company, particularly East Niv, and for working capital and general corporate purposes.

Certain insiders of the Company may participate in the Offering. Any such participation will constitute a "related party transaction" within the meaning of Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions ("MI 61-101"). The Company intends to rely on the exemptions from the formal valuation and minority shareholder approval requirements of MI 61-101 contained in sections 5.5(a) and 5.7(1)(a), respectively as the fair market value of the related party participation is not expected to exceed 25% of the Company's market capitalization.

The Offering is expected to close on or about May 5, 2026, and is subject to certain closing conditions, including, but not limited to, the receipt of all necessary regulatory approvals including the approval of the TSX Venture Exchange (the "TSXV") and the relevant securities regulatory authorities. The securities issued under the Offering will be subject to a hold period of four-months and one day from closing of the Offering.

The gross proceeds from the sale of CFT Units and FT Shares will be used to incur eligible resource exploration expenses that qualify as: (i) "Canadian exploration expenses", and (ii) as "flow-through critical mineral mining expenditures" (each as defined in the Income Tax Act (Canada)) (collectively, the "Qualifying Expenditures"). The Company will incur Qualifying Expenditures on or before December 31, 2027, and will renounce such Qualifying Expenditures in favour of the subscribers of the CFT Units and FT Shares with an effective date no later than December 31, 2026.

The securities described herein have not been, and will not be, registered under the United States Securities Act of 1933, as amended (the "1933 Act") or any state securities laws and may not be offered or sold within the United States or to, or for account or benefit of, U.S. Persons (as defined in Regulation S under the 1933 Act) unless registered under the 1933 Act and applicable state securities laws, or an exemption from such registration requirements is available.
