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

Further to the press release of Nov. 5, 2025, Sterling Metals Corp. has increased the size of its non-brokered private placement to up to 5,244,452 units at a price of $1.50 per unit and up to 2,666,662 charity flow-through units at a price of $2.30 per charity FT unit for aggregate gross proceeds of up to $14,000,000.60.

Each 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 $3 per common share for a period of two years from the closing of the offering. Each charity FT unit shall be composed of one common share issued on a flow-through basis and one warrant, having the same terms as the warrants comprising the units.

The company may pay certain eligible persons a cash commission equal to 6 per cent of the gross proceeds 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 net proceeds from the sale of the units will be used for general working capital purposes. The gross proceeds from the sale of the charity FT units will be used by the company to incur eligible Canadian exploration expenses that will qualify as flow-through critical mineral mining expenditures as such terms are defined in the Income Tax Act (Canada). 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.

It is anticipated that certain insiders of the company will participate in the offering.
