SIENNA RESOURCES INC. ANNOUNCES A FLOW-THROUGH PRIVATE PLACEMENT

Sienna Resources Inc. intends to complete a non-brokered flow-through private placement to raise $270,000 at a price of 15 cents per flow-through share. No warrants will be issued, and no finders' fees will be paid. Proceeds from the sale of the flow-through shares will be used on the company's existing projects in Saskatchewan.

Jason Gigliotti, president of Sienna Resources, stated: "This flow-through will enable Sienna to work on our Saskatchewan copper/gold project that is directly bordering Ramp Metals Inc, who are drilling right now. This small flow-through keeps dilution to a minimum and enables an initial work program in Canada as we also expect to be very active in the USA on our lithium and gold projects in the first half of 2026."

Flow-through shares issued in connection with the financing will be subject to a statutory hold period expiring four months and one day after closing of the financing. The financing is subject to final approval of the TSX Venture Exchange.
