 Vancouver, British Columbia--(Newsfile Corp. - October 23, 2025) - Gold Runner Exploration Inc. (CSE: GRUN) (FSE: 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 below;   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 Bullfrog,  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.

 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.
