GOLD RUNNER EXPLORATION RECEIVES FINAL PAYMENT INSTALLMENT FOR

CIMARRON SALE AND JOINT VENTURE AGREEMENT WITH SURFACE METALS INC.

Vancouver, Canada, October 22, 2025 – Gold Runner Exploration Inc. (CSE: GRUN, Frankfurt: CE7)

(“Gold Runner” or the “ Company”) is pleased to announce it has received final payment from Surface

Metals Inc. (“Surface Metals”), pursuant to the joint venture agreement with Gold Runner, announced in

the Company’s news release dated April 10, 2025 whereby Surface Metals (then ACME Lithium Inc.)

acquired 90% of the Cimarron gold project and Gold Runner retained 10% carried interest in the Cimarron

gold project (“Cimarron” or the “ Property”), subject to a 2.5% net smelter royalty to Nevada Select

Royalty.

The final payment received under the joint venture agreement is US$25,000 plus 166,666 common shares

of Surface Metals on a post consolidated basis (originally 500,000 shares pre -consolidation on a one new

for three former shares basis). Total consideration paid by Surface Metals to Gold Runner is US$149,000

plus 1,000,000 pre-consolidated or 333,333 post-consolidated common shares in Surface Metals. Surface

Metals shall have the right to acquire a further 5% interest from Gold Runner for US$500,000. Gold

Runner’s retained interest shall be carried until a completed preliminary economic assessment after which

each party will be responsible for its pro rata share of exploration costs.

The Property is comprised of 31 unpatented lode claims which overlap and control the 6 historically

producing claims around the San Antonio mine. The San Antonio mine was active from the early 1900’s to

the 1940’s, and the mine area received attention again in the 1980’s from a number of exploration companies

including Newmont and Echo Bay. Altogether, approximately 190 holes totalling about 54,000 feet (16,460

meters) were drilled in this effort, with gold intercepts greater than 1 opt encountered in several drill holes.

The drilling identified a shallow oxide gold resource, but the property did not progress to production. The

historic resource outlined includes a West, Central, and East target which totals greater than 50,000 ounces

of gold (see Map 2 belo w; reference is to an internal mining report by Peter Hahn to Budge Mining Ltd.

dated February 17, 1987). The resource for the Property was never made 43 -101 compliant as the data

predated the practice.

The resource is hosted in a series of Oligocene age volcanic rocks overlying Paleozoic strata, and younger

Miocene age intrusions. The target is a shallow, low sulfidation oxide gold system with strong structural

control. The mineralization is associated with silicification, brecciation, and iron oxides.

The Cimarron high-grade epithermal gold target is associated with the historic San Antonio mine located

in Nye County, Nevada approximately 30 kilometers North of the mining town Tonopah, Nevada.

The Property is situated in the northern portion of the San Antonio Mountain Range. Regionally, the

property is at the intersection of two prominent gold trends: The Walker -Lane trend which runs

approximately NW and hosts a number of mines including Bullfr og, Goldfield, and Rawhide; and an

approximately NNE trend of gold mines including Manhattan, Gold Hill, and the “world -class” Round

Mountain – according to the Kinross website, Round Mountain’s 15 millionth ounce of gold was poured as

of 2018). See Map 1 below.

The Fraser Institute mining survey has consistently ranked Nevada among the top 10 mining jurisdictions

in the world over its last 10 surveys, ranking Nevada number 1 in 2023.

About Gold Runner Exploration Inc:

Gold Runner Exploration is an experienced exploration company focused on the exploration and development of its

portfolio of gold and silver properties located in prolific mining districts of Canada and the USA.

Rock Creek gold project is Gold Runner's flagship asset, with 74 unpatented lode mining claims wholly owned and

controlled by the Company. Emboldened by the results coming out of Rock Creek, the Company strategically expanded

the land position with the acquisition of the nearby Dry Creek prospect and the acquisition of the Falcon silver -gold

prospect in September 2022. Between the three properties, all targeting similar mineralization and likely the same

hydrothermal system, Gold Runner Exploration now holds 239 total claims in close proximity of one another. These

three gold prospects are situated in a region with proven "world class" gold deposits (including Midas, Jerritt Canyon,

Betze-Post, Meikle, and Gold Quarry), where the potential of finding large, high- grade gold- silver deposits is

favourable.

Gold Runner also holds a 10% carried interest in the Cimarron project located in the San Antonio Mountains of Nye

County, Nevada, and comprised of 31 unpatented lode mining claims, including control of 6 historically producing

claims associated with the historic San Antonio mine. The property is located in the prolific Walker -Lane trend,

approximately 44 kms south of the "world class" Round Mountain deposit.
