Star Metro - Star Copper Announces Upsize To Flow Through Financing

VANCOUVER, BC / ACCESS Newswire / March 3, 2026 / Star Copper Corp. (CSE:STCU)(OTCQX:STCUF)(FWB:SOP) ("Star Copper" or the "Company"), a critical mineral exploration and development company, is pleased to announce, further to its news release dated February 17, 2026, that it has upsized and amended the terms of its previously announced non-brokered private placement of flow-through shares for gross proceeds of up to C$5,000,000 (the "FT Share Offering").

The Company will additionally offer (the "Upsize"): (i) 800,000 flow-through shares in the capital of the Company ("FT Shares") at a price of C$1.25 per share pursuant to the FT Share Offering for aggregate gross proceeds of C$1,000,000; and (ii) 1,156,069 flow-through units of the Company (each, a "FT Unit") to charitable purchasers at a price of C$1.73 per FT Unit for aggregate gross proceeds of up to C$2,000,000 (the "FT Unit Offering"; together with the FT Share Offering, the "Offering").

Each FT Unit will be comprised of one FT Share issued as a "flow-through share", as defined in subsection 66(15) of the Income Tax Act (Canada) (the "Tax Act") and one transferable common share purchase warrant (a "Warrant"). Each Warrant will also qualify as a "flow-through share" (as defined in subsection 66(15) of the Tax Act). Each Warrant will entitle the holder to purchase one non-flow-through common share of the Company (each a "Warrant Share") for a period of two years at a price of C$1.75 per Warrant Share.

The FT Unit Offering is being conducted concurrently with and in addition to the Company's FT Share Offering, which will proceed as announced on February 17, 2026 save for the Upsize.

Use of Proceeds

The gross proceeds from the Offering will be used to incur "Canadian exploration expenses" that are "flow-through critical mineral mining expenditures", within the meaning of the Tax Act, on the Company's flagship Star Project in British Columbia. The Company expects the flow-through funds to directly support an aggressive 2026 drill program, including expanded step-out drilling, deeper testing of priority targets, and follow-up drilling guided by ongoing three-dimensional geological modeling and planned deep-penetrating 3D geophysics.

Offering Terms and Closing

The Company anticipates closing the Offering on or about March 20, 2026 or such other date as the Company may determine, subject to the satisfaction of customary closing conditions, including the receipt of all necessary regulatory approvals. The Company may pay finder's fees in connection with the Offering in accordance with applicable securities laws and the policies of the CSE. All securities issued pursuant to the Offering will be subject to a statutory hold period in accordance with applicable Canadian securities laws and the policies of the CSE.

This news release does not constitute an offer to sell or a solicitation of an offer to sell any securities in the United States. The securities have not been and will not be registered under the United States Securities Act of 1933, as amended (the "U.S. Securities Act") or any state securities laws and 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 or an exemption from such registration is available.
