STERLING METALS ANNOUNCES UPSIZE OF PRIVATE PLACEMENT OF UNITS AND FLOW-THROUGH SHARES

Further to the press release of July 10, 2025, Sterling Metals Corp. has increased the size of its non-brokered private placement to up to 3,193,445 common shares in the capital of the company issued on a flow-through basis at a price of 42 cents per FT share and to up to 3,310,723 units of the company issued on a hard-dollar basis at a price of 35 cents per unit for aggregate gross proceeds of up to $2.5-million.

Each hard-dollar unit shall be composed of one common share in the capital of the company and one-half of one common share purchase warrant of the company. Each warrant shall entitle the holder thereof to acquire one common share at a price of 50 cents per common share for a period of two years from the closing of the offering.

All securities issued pursuant to the offering will be subject to a hold period of four months plus a day from the date of issuance and the resale rules of applicable securities legislation. The closing of the offering is subject to certain conditions, including, but not limited to, the receipt of all necessary regulatory and other approvals, including the approval of the TSX Venture Exchange. The net proceeds from the sale of the units will be used for general working capital purposes, and the gross proceeds of the offering received from the sale of the FT shares will be used to incur Canadian exploration expenses that will qualify as flow-through critical mineral mining expenditures as such terms are defined in the Income Tax Act (Canada).
