Vancouver, B.C. December 9, 2025: Sun Summit Minerals Corp. (“Sun Summit” or the “Company“) (TSX-V: SMN; OTCQB: SMREF) is pleased to announce a non-brokered private placement (the “Private Placement“) of up to 50,000,000 charity flow-through shares of the Company (each, a “Charity FT Share“) at a price of $0.14 per Charity FT Share for aggregate gross proceeds to the Company of up to $7 million. Each Charity FT Share will qualify as a flowthrough share within the meaning of subsection 66(15) of the Income Tax Act (Canada) (the “Tax Act“).

The Company intends to use all of the gross proceeds of the Private Placement for exploration of the Company’s JD, Theory and Buck properties and any other Canadian properties that the Company may acquire, provided that the Company will use an amount equal to the gross proceeds received by the Company from the sale of the Charity FT Shares to incur eligible “Canadian exploration expenses” that will qualify as “flowthrough mining expenditures” as such terms are defined in the Tax Act.

“This capital will fully fund our 2026 exploration program and help accelerate our progress towards an initial mineral resource estimate at JD. The calibre of investors who have agreed to participate in this offering provides additional validation for the quality of the JD Project,” said Niel Marotta, CEO of Sun Summit.

The closing of the Private Placement is subject to certain closing conditions, including the approval of the TSX Venture Exchange (the “TSXV“). The Company may pay finder’s fees in cash or securities to certain arm’s length finders (each, a “Finder“) engaged in connection with the Private Placement, subject to the approval of the TSXV. Eventus Capital Corp. has been appointed as a Finder in connection with the Private Placement. The Charity FT Shares issued pursuant to the Private Placement will be subject to a four-month hold period in accordance with applicable securities laws.

The Charity FT Shares offered have not been registered under the U.S. Securities Act of 1933, as amended, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements. This news release shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the Charity FT Shares in any State in which such offer, solicitation or sale would be unlawful.
