CORE SILVER COMPLETES PRIVATE PLACEMENT OF $1.287M

Core Silver Corp. has completed a non-brokered private placement, issuing 2,340,500 flow-through units at a price of 55 cents per FT unit for gross proceeds of $1,287,275. The offering was increased from the approximately $1-million previously announced on Sept. 29, 2026. Each FT unit is composed of one common share in the capital of the company to be issued as a flow-through share within the meaning of the Income Tax Act (Canada) and one-half of one transferrable common share purchase warrant issued on a non-flow-through basis. Each whole FT warrant entitles the holder to receive one non-flow-through common share in the capital of the company at a price of 85 cents per warrant share at any time before the date that is two years following the date of issuance.

All securities issued pursuant to the offering are subject to a statutory hold period of four months and a day from issuance. No finders' fees were paid in connection with the offering.

The gross proceeds from the sale of the FT units will be used by the company to incur eligible Canadian exploration expenses that will qualify as flow-through mining expenditures as such terms are defined in the Income Tax Act (Canada) related to the company's Touleary project located in Yukon, Canada, on or before Dec. 31, 2027. All qualifying expenditures will be renounced in favour of the subscribers, effective Dec. 31, 2027, and as otherwise required and permitted under the act.

An insider of the company subscribed for a total of 45,000 FT units under the offering, which is a related-party transaction within the meaning of Multilateral Instrument 61-101 (Protection of Minority Security Holders in Special Transactions). The issuance to the insider is exempt from the formal valuation requirement of MI 61-101 by virtue of the exemption contained in Section 5.5(a) as the units purchased by the insider do not exceed more than 25 per cent of the market capitalization of the company and from the minority shareholder approval requirement of MI 61-101 by virtue of the exemption contained in Section 5.7(1)(b) of MI 61-101 in that the fair market value of the securities distributed to the insider in the offering is not more than $2.5-million.

About Core Silver Corp.

Core Silver is a Canadian mineral exploration company focused on the discovery and advancement of high-potential precious and base metal projects in Canada. The company's Touleary project is located approximately 115 kilometres south of Dawson City, Yukon. Touleary hosts a drill-confirmed, polymetallic volcanogenic massive sulphide system containing copper, gold, zinc and silver mineralization. Historical drilling at the Discovery zone has identified significant mineralization, including 2.25 metres grading 7.18 per cent copper, 3.55 grams per tonne gold, 4.30 per cent zinc and 116 g/t silver. With only 335 metres of the approximately 3.5-kilometre interpreted geophysical trend having been tested by historical drilling, the company believes Touleary offers substantial exploration potential. Multiple additional targets remain untested across the property, highlighting the potential for further discoveries within this prospective VMS district.

In addition, Core Silver holds 100-per-cent ownership of the Blue property, comprising approximately 114,074 hectares (1,140 square kilometres) in the Atlin mining district of northwestern British Columbia. The Blue property hosts multiple mineralized systems, including the Silver Lime and Laverdiere projects, which are prospective for high-grade silver, copper, gold and associated base metals. The company continues to advance its exploration strategy across both properties, targeting new discoveries and the expansion of known mineralized systems.
