Gold Runner Exploration Expands Golden Girl

Property in the Golden Triangle of B.C.

Following Completion of Airborne Magnetic

Survey and Initial Exploration Results

Vancouver, British Columbia--(Newsfile Corp. - September 10, 2026) - Gold Runner Exploration Inc.

(CSE: GRUN) (FSE: CE70)

("

Gold Runner

" or the "

Company

") is pleased to announce that it has

completed processing and interpretation of the airborne magnetic and radiometric surveys conducted on

the Golden Girl property (the "Property") in the Golden Triangle of British Columbia. Due to the positive

survey results, as well as exploration efforts on the ground, the Company has actively chosen to stake

additional claims in the area and has more than doubled the size of the Golden Girl Property from 5,873

hectares ("ha") to 14,480 ha.

The newly staked claims cover additional large areas of recent glacial retreat and permanent snowpack

abatement between the original claim boundaries centered around the newly discovered Gold Stack

Trend and the past producing Snip Mine. Multiple new exploration targets within the expanded claims

have been identified with the help of magnetic and radiometric anomalies determined with the recently

concluded geophysical survey. Initial prospecting, mapping and systematic sampling has been carried

out on a number of these new showings with the goal of adding potential drill targets for the upcoming

inaugural drill program scheduled for the summer of 2027. The new claims have been duly filed,

registered, and submitted for approval.

The Company's successful 2026 exploration program focused on prospecting, systematic sampling and

mapping of new and historic showings in preparation for drilling. During the program a total of 473

samples were collected (290 grab samples, 122 channel samples, and 61 silt samples). Assays are

pending on 413 samples collected. In addition to the airborne magnetic and radiometric surveys, the

company also completed a unmanned aerial vehicle (UAV) photogrammetry and LiDAR survey on the

Golden Girl Property which among other things will help identify the extent of mineralization and facilitate

3D modeling as exploration progresses through successive future drilling campaigns.

Gold Runner's Chief Executive Officer, Chris Wensley, states, "In the face of such encouraging data from

both our geophysics efforts and what we're seeing on the ground, it became immediately apparent that

acquiring the adjoining claims at Golden Girl was imperative. The additional claims, once approved, will

more than double the Company's footprint in this highly prospective ground extending from Snip to the

Alaska/B.C. border. We are very keen and excited to learn more about what these additional claims, and

the entire Golden Girl Property, hold. This lays a strong foundation for years of exploration and

development to come."

Golden Girl Property Highlights:

The Golden Girl Property covers 14,480 ha in the prolific Iskut River region of Northwestern British

Columbia, located just 17 km from the Snip Mine and 14 km from the Bronson Airstrip.

Discovery exploration in 2024 identified a major new gold-silver system measuring 12 km by 7 km

with high grade gold-silver mineralization:

Grab samples assayed up to 11.28 g/t Au, 3,262 g/t Ag, 5.37% Cu, 20% Pb, and 14% Zn.

Channel cuts assayed up to 3.74 g/t Au, 2,105.45 g/t Ag, 0.88% Cu, 5.48% Pb, and 7.42%

Zn.

Multiple new gold-silver mineralized zones have been identified during the 2026 exploration

season, including the Gold Stack Trend which has a strike of 350 metres ("m") and contains

samples with grades up to 396.66 g/t AuEq (11.22 g/t Au, 25,306 g/t Ag, 2.96% Cu, 8.19% Pb,

and 5.89% Zn) and remains open (see the Company's news release dated August 31, 2026).

High-grade mineralization occurs in structurally controlled shear zones with sulphide-rich veins,

stockwork, and breccias, similar to the nearby past-producing Snip Gold Mine (which historically

produced ~1M oz Au, 390k oz Ag, and over 249k kg Cu). The reader is reminded that the

information provided herein from neighbouring projects and properties is not necessarily indicative

of resources and should not be relied upon for the determination of mineralization or potential

results of the Company's properties.

More than 95% of the Property has never undergone systematic modern exploration. Recent rapid

glacial retreat and melting snowpacks have exposed vast areas of previously buried bedrock,

opening large, untouched tracts of ground for immediate mapping and sampling.

Goliath Resources (TSXV: GOT) and Juggernaut Exploration (TSXV: JUGR) are partners within

the B-ALL Syndicate ("B-ALL"), the optionor of Golden Girl Property, holding respectively, 4% and

13% interest in B-ALL, and as such are important strategic partners of Gold Runner.
