Sun Summit Reports Significant High-Grade
Gold, Silver and Copper Mineralization from
Rock Samples Across the JD Project,
Toodoggone District
Vancouver, British Columbia--(Newsfile Corp. - October 29, 2025) - Sun Summit Minerals Corp. (TSXV:
SMN) (OTCQB: SMREF) (
"Sun Summit"
or the
"Company"
) is pleased to report assay results from
rock samples collected during a project-wide geological mapping and prospecting program at the JD
Project, Toodoggone Mining District, north-central British Columbia.
Highlights:
New high-grade copper-silver discovery:
Hand trenching through gossanous soil, south of the
Finn to Creek corridor, revealed semi-massive to massive copper sulfides in a discrete vein
traced in subcrop for over 5 meters. Two samples returned very high-grade copper and silver:
73.6% copper with 6,320 g/t silver (J506225) and 72.4% copper with 4,370 g/t silver
(J506222)
. The strike-extent of this zone of mineralization is unknown.
New priority drill target
: Systematic rock samples taken from 1980's historical trenches at Belle
North, south of the Finn to Creek corridor returned high-grade gold and silver results:
14.2 g/t gold
with 56.6 g/t silver (J506201) and 9.46 g/t gold with 43.5 g/t silver (J507946)
. The Belle North
vein-system has never been drill-tested and represents a priority gold-silver target for upcoming
drill programs.
High-grade gold and silver mineralization along the Finn to Creek Corridor:
Sampling north
of the historical JD West and Schmidt showings returned high-grade gold and silver results:
43.6
g/t gold with 57.6 g/t silver (J507915) and 26.9 g/t gold with 38.9 g/t silver (J507914)
. Both
historical high-grade showings have not been adequately drill-tested and represent priority gold-
silver targets for upcoming drill programs.
Comprehensive project-wide rock sampling:
The field program included the collection of over
650 rock samples across the JD Project with results from 532 samples still pending. And
additional 8 samples were taken for whole rock analysis to assist with lithogeochemical
interpretation.
Additional drill results from the 6,864 meter drill program pending:
The final batch of core
samples have now been shipped to the lab with results from 20 drill holes pending.
"We are pleased to report new assay data from recently completed geological mapping and prospecting
surveys from across the JD Project, including the discovery of a very high-grade zone of copper-silver
mineralization." said Niel Marotta, CEO of Sun Summit Minerals. "This work will greatly assist with drill
target definition in conjunction with interpretation of the 2025 IP surveys. The company is planning further
work, including additional sampling and drilling, to better define the extent and grade of the discovered
mineralization."
Geological Mapping and Prospecting
Project-wide geological mapping and prospecting focused on advancing the geological and structural
understanding of the Finn to Creek corridor, as well as target refinement at the Belle North, Oxide Peak,
JD porphyry trend and McClair east areas, was conducted over a 20+ day initiative. A total of 1,387
geological waypoint stations were established and over 650 rock chip samples were collected.

Finn to Creek Corridor:
Geological mapping and prospecting along the Finn to Creek corridor was
focused on two key target areas; the historic Schmidt and JD West zones. The Schmidt zone, 1.4 km
west of the Finn Zone, consists of a boulder train of siliceous breccias and banded quartz veins that have
historically yielded assays of up to 326 g/t Au with 1,535 g/t Ag, and 64.5 g/t Au with 6,151 g/t Ag.
Sampling north of the main target area returned 43.6 g/t gold with 57.6 g/t silver (Figures 1 and 2, Table
1).
The JD West target covers the gap between the Finn and Schmidt zones where the potential strike-
extension of the Finn zone is locally exposed in historic trenches and has been drill tested in several,
widely-spaced, shallow holes (see
February 1, 2024
news release). The area is spatially associated with
a broad gold-in-soil geochemical anomaly and the historic Ag-Carbonate zone where grab sampling
from quartz-carbonate breccias, hosted along steeply dipping, north-striking normal faults, yielded up to
14.1 g/t Au with 1,601 g/t Ag. Sampling ~150 meters north of the main JD West area returned up to 26.9
g/t gold with 38.9 g/t silver (Figures 1 and 2, Table 1).
The Schmidt and JD West targets have not been adequately drill-tested and both areas represent
priority targets for future drill programs.

New High-Grade Copper-Silver target - A535:
Prospecting by the soil crew working on the Kadah North
soil grid discovered an area of gossanous soil approximately 3.0 km south of the Finn to Creek corridor
in an area lacking historic rock or soil sampling. Hand trenching revealed semi-massive to massive
copper sulfides with strong malachite in a discrete vein traced in subcrop for over five meters. Two
samples returned very high-grade copper and silver:
73.6% copper with 6,320 g/t silver (J506225)
and 72.4% copper with 4,370 g/t silver (J506222)
. The strike-extent of this zone of high-grade
copper-silver mineralization is unknown. Further trenching and prospecting is warranted.

Belle North Trenches
:
Gold-silver mineralization at the Belle North target (Figure 5) is hosted in a
northwest - southeast striking structural zone, traced in historic trenching for over 200 meters. The zone
is characterized by a ~20 meter wide, northwest trending corridor of argillic alteration cored by sulphide
bearing (pyrite, galena, and sphalerite) siliceous breccias and at least 5 parallel epithermal veins with
minor barite. Historic sampling by Manson Creek Resources in 1985 reportedly returned up to 107 g/t
gold and 103 g/t silver
1
. Sampling of the trenches in 2025 returned up to 14.20 g/t gold with 56.6 g/t
silver (J506201) and 9.46 g/t gold with 43.5 g/t silver (J507946). Based on the mapping and sampling
results, the Belle North target is considered a priority area for future drill programs.

Next Steps
Assay and geochemical results from an additional 532 rock samples are pending. The majority of the
pending results are from detailed mapping and prospecting traverses across the JD Porphyry Trend,
along McClair Creek. These results, together with soil geochemical results will be reported once
received and interpreted.
All drill core samples from the 6,864 meter, 21 hole program have now been shipped to the lab, including
the four follow-up holes northwest of previously released CZ-25-007 (78.0 meters of 3.72 g/t gold from
30.0 meters downhole, see the Company's news release dated
September 8, 2025
).

Quality Assurance and Quality Control
Rock samples were bagged onsite and delivered to ALS Laboratories in Kamloops, British Columbia.
ALS is certified with ISO/IEC 17025:2017 and ISO 9001:2015 accreditation from the Standards Council
of Canada.
Rock samples were prepared (PREP-31) and then analysed for 48 elements by ICP-MS on a 0.25-gram
aliquot using a four-acid digestion (method ME-MS61). Gold was analyzed by fire assay on a 30-gram
aliquot with an AES finish (Au-ICP21). Samples that returned >10 parts per million (ppm) gold were re-
analyzed by fire assay using a gravimetric finish on a 30-gram aliquot (method Au-GRA21). Overlimit
samples (e.g. Ag, Cu) were re-analyzed using an ore-grade, four-acid digestion and ICP-AES finish
(method ME-OG62). Samples that returned > 50% Cu were re-analyzed using a 4-acide digestion and a
volumetric finish (Cu-VOL61).
In addition to ALS Global laboratory QA/QC protocols, Sun Summit implements a rigorous internal
QA/QC program that includes the insertion of duplicates, certified reference materials (standards
prepared by an independent lab) and blanks into the sample stream.
Rock samples taken while prospecting referenced in this news release are selective in nature and
collected to determine the presence or absence of mineralization and may not necessarily reflect the true
nature and grade of the underlying mineralization.

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.
