BITTERROOT RESOURCES LTD. CLOSES FIRST TRANCHE

OF PRIVATE PLACEMENT

Bitterroot Resources Ltd. (symbol BTT, TSX-V) has closed the first tranche of the 20,000,000- unit non-brokered private placement announced on September 16, 2026. The Company has placed 15,137,883 units priced at C$0.12, consisting of one common share and one-half common share purchase warrant exercisable at C$0.20, expiring October 8, 2028. Gross proceeds of the first tranche are C$1,816,546.

The proceeds of the private placement will be used to fund approximately 10,000 metres of drilling in 15-20 holes, plus associated exploration costs, at the 51%-owned LM Nickel-Copper Project in the Upper Peninsula of Michigan and for general working capital. Bitterroot's Michigan subsidiary Trans Superior Resources, Inc. (Trans Superior) is the LM Project operator, with the remaining 49% held and funded by Michigan-based, privately held, Below Exploration Inc.

Additionally, Trans Superior has entered into an agreement with the U.S. Department of War (DoW) whereby the DoW will provide up to US$5,223,431 in Defense Production Act (DPA) Title III funding to Trans Superior. The DoW investment will reimburse 50% of approved exploration and associated costs incurred by the joint venture on the LM Project. The DPA Title III funding is non-dilutive.

Upon 15 days-notice, Bitterroot Resources has the right to accelerate the warrant expiry date if the 20-day volume weighted average trading price of the common shares on any public stock exchange exceeds C$0.40 per share.

Finders' fees consisting of C$63,876 plus 532,000 broker warrants priced at C$0.20 and expiring October 8, 2028 were paid in connection with the private placement. Any common shares issued pursuant to the exercise of broker warrants will be subject to a four-month hold period expiring February 9, 2027.

This news release does not constitute an offer or solicitation to sell any of these securities in the United States. The securities will not be registered under the United States Securities Act of 1933, as amended ("the US Securities Act"), or under any State securities laws. The securities may not be offered or sold within the United States or to U.S. Persons unless registered under the U.S Securities Act and applicable State securities laws, unless an exemption from such registration is available.
