VANCOUVER, British Columbia, Nov. 12, 2025 -- Rio Silver Inc. (the “Company” or “Rio Silver”) (TSX.V: RYO) (OTC: RYOOF)

is pleased to announce that it has closed its non-brokered private placement (the “Offering”), previously announced on

September 24, 2025, by issuing an aggregate of 22,000,000 units of the Company (the “Units”) at a price of $0.10 per Unit for

gross proceeds of $2,200,000.

Each Unit is comprised of one common share of the Company and one share purchase warrant (a “Warrant”), with each

Warrant exercisable to purchase an additional common share of the Company at a price of $0.15 per common share for a

period of three years from the date of issue, subject to early expiry in the event that the closing price of the common shares of

the Company is $0.25 or higher for fifteen consecutive trading days at any time after the closing of the Offering, upon which the

Warrants will expire thirty calendar days after notice to warrant holders through the Company’s announcement with respect to

the early expiry date.

In connection with the closing of the Offering, the Company paid finders’ fees of $70,920 in cash and issued 709,200 finder’s

warrants, having the same term as the Warrants, in payment of finder fees. All securities issued are subject to a statutory 4-

month hold period expiring on March 12, 2026.

The Company intends to use the net proceeds of the Offering towards the exploration and development of the Company’s

projects in Peru, exploration and development of the Gerow Lake project in Northern Ontario and for general working capital

purposes. Notwithstanding the foregoing, the Company will not use the proceeds of the Offering on the Maria Norte project

until the TSX Venture Exchange has approved of the acquisition of the Maria Norte project, announced March 26, June 25,

August 12 and September 17, 2025.
