Gold Runner Exploration Upsizes Non-Brokered Private Placement Financing of Flow-Through Units and Charity Flow Through Units to $3,100,000

Gold Runner Exploration Inc. (CSE: GRUN) (FSE: CE70) ("Gold Runner" or the "Company") is pleased to announce that due to strong investor demand it is upsizing its previously announced private placement financing (the "Offering") from proceeds of up to $1,500,000 to proceeds of up to $3,100,000 consisting of Critical Minerals Exploration Tax Credit ("CMETC") flow-through units ("FT Units") of the Company at a price of $1.45 per FT Unit and charity flow-through Units ("Charity FT Units", and collectively with the "FT Units", the "Units") at a price of $1.45 per Charity FT Unit. The Company reserves the right to increase the size of the Offering, subject to the approval of the Canadian Securities Exchange (the "Exchange"). Each Unit will be comprised of one common share ("Common Share") of the Company and one Common Share purchase warrant (the "Warrants"), and each Warrant will entitle the holder thereof to acquire one Common Share of the Company at a price of $1.50 per Common Share for a period of 36 months from the date of issuance.

Net proceeds from the Offering will be used for exploration of the Company's Golden Girl property situated in the Golden Triangle of British Columbia. The Company optioned the Golden Girl Property from the B-ALL Syndicate, the same team that generated and staked Goliath Resources (TSXV: GOT), Surebet Discovery, and contributed to advancing that discovery to where it is today. The B-ALL Syndicate also generated and staked the Big One discovery that was subsequently optioned to Juggernaut Exploration (TSXV: JUGR,OTC:JUGRF) and is situated adjacent to Galore Creek. Golden Girl is located approximately midway between Goliath's Surebet Discovery and Juggernaut's Big One discovery.

This Offering qualifies for the Critical Mineral Exploration Tax Credit (CMETC) and each Unit shall be comprised of one common share of the Company that will qualify as a CMETC "flow-through share" (within the meaning of subsection 66(15) of the Income Tax Act (Canada)). The Company will incur expenditures that will qualify as "Canadian Exploration Expenses" and "flow-through critical mineral mining expenditures" as those terms are defined in the Income Tax Act (Canada), which will be renounced to the purchasers of the FT Units with an effective date no later than December 31, 2026.

The Company may pay finder's fees to eligible arm's-length third parties on gross proceeds of the Offering, consisting of 6% cash and/or 6% broker warrants, with each broker warrant exercisable for a period of 36 months from the date of issuance at a price of $1.50 per Common Share.

The securities have not been, and will not be, registered under the United States Securities Act of 1933, as amended (the "U.S. Securities Act"), or any U.S. state security laws, and may not be offered or sold in the United States without registration under the U.S. Securities Act and all applicable state securities laws or compliance with requirements of an applicable exemption therefrom. This press release shall not constitute an offer to sell or the solicitation of an offer to buy securities in the United States, nor shall there be any sale of these securities in any jurisdiction in which such offer, solicitation or sale would be unlawful.

The securities issued under the Offering will have a hold period expiring four months and one day from the date of issuance pursuant to applicable Canadian securities laws. Closing of the Offering remains subject to regulatory approvals, including approval of the Exchange.

The Company also announces that, further to its press release dated February 27, 2026, the Company has corrected the aggregate number of stock options issued from 2,500,000 stock options previously disclosed to 1,250,000 stock options ("Options") granted and has issued such Options to certain directors, officers, employees, and consultants of the Company. The Options have the same terms as previously disclosed with an exercise price of $1.22 per common share, vesting immediately, expiring five (5) years from the date of grant, and are subject to approval by the Canadian Securities Exchange.

On Behalf of the Board of Directors,

"Chris Wensley"
