Sun Summit Announces the Completion of its

2025 Exploration Program at the JD Project,

Toodoggone Mining District; Assay Results

Pending

Vancouver, British Columbia--(Newsfile Corp. - October 14, 2025) - Sun Summit Minerals Corp. (TSXV:

SMN) (OTCQB: SMREF) (

"Sun Summit"

or the

"Company"

) is pleased to announce the 2025

exploration program has now been completed at the JD Project, Toodoggone Mining District, north-

central British Columbia.

Highlights:

Extensive drill program completed:

21 drill holes were completed for a total of 6,864 meters.

Drilling in 2025 represented a 37% increase in the overall meterage from the original planned

5,000 meters. Highlights include:

Fifteen holes for 5,103 meters were drilled at the epithermal Au-Ag Creek Zone. Results

from the first hole, CZ-25-007, demonstrated strong potential for near surface high-grade and

bulk-tonnage style gold mineralization (78.0 meters of 3.72 g/t gold from 30.0 meters

downhole, see news release September 8, 2025 entitled "Sun Summit Drills 78.0 Meters of

3.72 g/t Gold Including 19.1 Meters of 7.50 g/t Gold at the JD Project, Toodoggone District,

B.C."). Logging and sampling of the drill core from the three final CZ-25-007 follow-up holes

remains ongoing.

Four holes for 950 meters were drilled at the epithermal Au-Ag near-surface, shallow Finn

Zone. Holes were designed to follow-up historic drill results and explore at depth (e.g., 35.7

meters of 7.26 g/t gold with 94 g/t silver, JD95-0472).

Two holes for 811 meters were drilled at the Belle South Cu-Au porphyry target located at the

southern end of ~12 km long JD Porphyry Trend, which aligns with the significant McClair

Creek alteration zone.

Results are pending for the remaining 20 drill holes including 14 holes from the Creek

Zone, four holes from the Finn Zone and two holes from the Belle South porphyry target.

The 2025 exploration program was completed on target date and within budget even

while adding a second drill later in the season.

Comprehensive surface sampling and geological mapping:

The field program included the

collection of over 1,500 soil samples and over 120 rock samples across numerous target areas.

Detailed geological mapping along McClair Creek and across the greater JD Project was

completed with the aim of defining the structural and stratigraphic setting of the epithermal gold-

silver systems as well as potentially related porphyry copper-gold systems.

Extensive geophysical surveying:

Induced polarization (IP) surveys across the JD Porphyry

trend consisted of over 35 line kilometers which defined a broad 8.5 km long chargeability-high

anomaly which significantly enhances the project's prospectivity for porphyry-related copper and

gold systems. A further 23 line kilometers of IP surveying was also completed across the

significant Finn to Creek corridor aimed at defining additional epithermal-related gold-silver

targets. Total IP survey coverage in 2025 was over 58 line kilometers.

"We are extremely proud to have successfully completed our second ever exploration program at the JD

Project, since we acquired the property in February 2024. The 2025 program was more than twice as

large as the inaugural program in 2024. All told, we have completed a significant drill program

comprising 9,400 meters of drilling over 33 drill holes since 2024 and, with the success of Hole CR-25-

007, we are continuing to build on the impressive results from our 2024 drill program at the Creek Zone,"

said Niel Marotta, CEO of Sun Summit Minerals. "Additionally, we were able to add a second drill rig

late in the season to ramp up our work program in order to be able to complete drilling at the Finn Zone

and to conduct our first-ever drill test at the Belle South porphyry copper-gold target. It is a testament to

talent and hard work of our geological planning and field execution teams that we were able to execute a

large, complex program on time and on budget with no downtime or weather-related delays. We hit the

ground running in early June 2025 and shut the last drill hole down on October 6, 2025 for a total of

greater than 1,670 person-days spread across four months with 10 key contractors".

Summary and Next Steps

Core samples from all recently completed drill holes have been sent to the lab for assay and

geochemical analyses and will be reported once received and reviewed. Assay results will provide

important vectors for follow-up drill planning and targeting for 2026 which is well underway. Geochemical

results and associated inverted chargeability and resistivity models from the IP surveys, together with

results from the recently completed mapping, prospecting and geochemical surveys, will inform drill

targeting elsewhere on the property.

National Instrument 43-101 Disclosure

This news release has been reviewed and approved by Sun Summit’s Vice President Exploration, Ken

MacDonald, P. Geo., a “Qualified Person” as defined in National Instrument 43-101 Standards of

Disclosure for Mineral Projects of the Canadian Securities Administrators. Some technical information

contained in this release is historical in nature and has been compiled from public sources believed to

be accurate. The historical technical information has not been verified by Sun Summit and may in some

instances be unverifiable dependent on the existence of historical drill core and grab samples.

Community Engagement

Sun Summit is engaging with First Nations on whose territory our projects are located and is discussing

their interests and identifying contract and work opportunities, as well as opportunities to support

community initiatives. The Company looks forward to continuing to work with local and regional First

Nations with ongoing exploration.

About the JD Project

The JD Project is located in the Toodoggone mining district in north-central British Columbia, a highly

prospective deposit-rich mineral trend. The project covers an area of over 15,000 hectares and is in

close proximity to active exploration and development projects, such as Thesis Gold’s Lawyers and

Ranch projects, TDG Gold’s Baker-Shasta projects, Amarc Resource’s AuRORA project, Centerra’s

Gold’s Kemess East and Underground projects, as well as the past-producing Kemess open pit copper-

gold mine.

The project is 450 kilometres northwest of the city of Prince George, and 25 kilometres north of the

Sturdee airstrip. It is proximal to existing infrastructure in place to support the past-producing Kemess

mine, including roads and a hydroelectric power line.

The JD Project is in a favourable geological environment characterized by both high-grade epithermal

gold and silver mineralization, as well as porphyry-related copper and gold mineralization. Some

historical exploration, including drilling, geochemistry and geophysics, has been carried out on the

property, however the project area is largely underexplored.

About Sun Summit

Sun Summit Minerals (TSXV: SMN) (OTCQB: SMREF) is a mineral exploration company focused on the

discovery, expansion and advancement of district scale gold and copper assets in British Columbia. The

Company’s diverse portfolio includes the JD and Theory projects in the Toodoggone region of north-

central B.C., and the Buck Project in central B.C.
