Sun Summit Drills Strongest Interval to Date at
the Creek Zone: 81.0 Meters of 4.80 g/t Gold
from 26 Meters Downhole, Including 14.0
Meters of 19.81 g/t Gold at the JD Project,
Toodoggone District, B.C.
Vancouver, British Columbia--(Newsfile Corp. - November 25, 2025) - Sun Summit Minerals
Corp. (TSXV: SMN) (OTCQB: SMREF) (
"Sun Summit"
or the
"Company"
) is pleased to report the
remaining assay results from all 2025 drilling at the Creek Zone, JD Project, Toodoggone Mining
District, north-central British Columbia.
Drill hole
CZ-25-021
returned the strongest interval of near-surface gold mineralization drilled to date at
the Creek Zone:
81.0 meters of 4.80 g/t gold starting at 26.0 meters downhole, including 14.0
meters of 19.81 g/t gold
. The drill hole tested the down-dip extent of significant gold mineralization
intersected in drill hole CZ-25-007 (
78.0 meters of 3.72 g/t gold including 19.1 meters of 7.50 g/t
gold
, see news release dated
September 8
th
, 2025
). This interval extends bulk-tonnage and high-grade
gold mineralization to a vertical depth of approximately 150 meters from surface (Figures 2 and 3).
Highlights:
Drill Hole CZ-25-021 tested the down-dip extent of significant gold mineralization
intersected in drill hole CZ-25-007 and returned an equally strong zone of near-surface,
continuous gold mineralization punctuated with high-grade veins:
81.0 meters of 4.80 g/t gold from 26.0 meters downhole
, including
34.0 meters of 9.07 g/t gold, and including
high-grade intercepts of:
155 g/t Au over 1.0 meter at 42.0 meters downhole
101 g/t Au over 1.0 meter at 54.0 meters downhole
30.6 g/t Au over 1.3 meter at 78.0 meters downhole
Confirms the strong high-grade gold potential of the Creek Zone:
The 81.0-meter interval in
CZ-25-021 is down-dip from the significant interval intersected in CZ-25-007 and extends the zone
at depth with strong continuity extending approximately 150 meters from surface. Based on these
results, management believes that further drilling down-dip and stepped to the northeast is
warranted.
Establishing significant scale-potential at the Creek Zone:
Drilling in 2025 outlined a
significant, fault-bounded northwest-trending mineralized corridor that spans ~750 meters by 300
meters and ~150 meters vertical depth from surface (Figure 1). Highlight intervals across the
Creek Zone in 2025 include:
46.0 meters of 0.9 g/t gold from 20.0 meters downhole
and
1.0 meters of 158.5 g/t
gold
from 134.0 meters downhole
and
17.0 meters of 1.25 g/t gold from 151.0 meters
downhole
in hole CZ-25-008.
17.0 meters of 2.32 g/t gold from 308.5 meters downhole
including
13.5 meters of 2.85
g/t Au
in hole CZ-25-016, approximately 460 meters southeast of CZ-25-021 (Figures 1 and
2).
15.0 meters of 1.39 g/t gold from 87.0 meters downhole
, including
10.5 meters of 1.75
g/t gold
in hole CZ-25-018, approximately 100 meters northwest of CZ-25-021 (Figures 1
and 2).
Every hole intersected gold mineralization and the system remains open in all
directions across the corridor.
Metallic screen analyses underway:
A large selection of Creek Zone drill core from 2024 and
2025 drilling has been submitted for metallic screen analysis to better understand the gold
deportment.
Finn Zone and Belle South Porphyry Zone results pending:
Assay results are pending from
four drill holes from the Finn Zone, located approximately 3.5 km east of the Creek Zone as well as
two drill holes from a compelling porphyry target at Belle South, 8 km southeast of the Creek Zone.
"We are pleased to announce very exciting new drill results from the 2025 program on the Creek Zone.
The 2025 program was successful in demonstrating large intervals of near-continuous gold and silver
mineralization in the near surface portion of the Creek Zone, highlighting high-grade gold in veins, while
also identifying important structural features. Every completed drill hole intersected gold-silver
mineralization and continues to demonstrate there is a zone of gold and silver mineralization with
significant width and depth expansion potential, punctuated by well-mineralized quartz-carbonate veins
with some of the highest-grade gold drill intercepts known from the JD property," said Niel Marotta, CEO
of Sun Summit Minerals. "The final hole of this year's drill program at the Creek Zone returned the largest
gram-meter intercept of both the 2024 and 2025 programs. While we await more exciting results from
the Finn and Belle South Zones, we continue modelling and planning for follow-up drill holes at the Creek
Zone, which remains open for expansion. Our newest iteration of a robust 3D geological and structural
model will inform targeting for the next season and gives us a strong technical advantage relative to
historical drilling which failed to recognize the interplay of important orientations of the various structural
fabrics inherent to the mineralization domains, including bulk-tonnage and high-grade potential of the
Creek Zone."

2025 Creek Zone Drill Program
Drilling in 2025 at the Creek Zone was designed to investigate the lateral and vertical extent of high-
grade and bulk-tonnage gold mineralization (Figures 1 and 2). Results of 15 HQ diameter drill holes for
5,110 meters of drilling are being used to evaluate the newly modeled structural architecture of the zone.
These holes were designed to systematically test the vein-controlling structures on 50 to 100 meter
pierce-points covering a strike-length of over 800 meters and a down-dip extent of over 200 meters
(Figures 1 and 2). A total of 3,079 samples were taken representing an average sample length of 1.64
meters.

Drill Hole CZ-25-021
Drill hole CZ-25-021 was collared from the same pad as CZ-25-007 (78.0 meters of 3.72 g/t gold
including 19.1 meters of 7.50 g/t gold, see news release dated
September 8
th
, 2025
), however it was
swung to the southeast with a 230
o
azimuth and a steeper dip of -68
o
(Table 3). The pad is 75 meters to
the north of hole CZ-24-004 (122.53 metres of 2.11 g/t gold including 4.04 metres of 46.78 g/t gold, see
October 2, 2024
news release) and stepped out 100 meters west of hole CZ-24-005 (57.95 meters of
2.69 g/t gold including 19.50 meters of 7.31 g/t gold, see
October 16, 2024
news release, Figure 1).
The hole was designed to test the down-dip extent of gold mineralization intersected in drill
hole CZ-25-007
.

The upper interval of strong disseminated and high-grade vein-hosted gold mineralization in CZ-25-021
(e.g.,
81.0 meters of 4.80 g/t gold
, Table 1) is approximately 25 to 50 meters down-dip and offset
along strike from the significant zone of gold mineralization in CZ-25-007 (Figure 3). These intercepts
are interpreted by management to represent a new zone of mineralization that trends parallel to- and/or
along-strike from the main, steeply-dipping northwest-striking vein-sets (e.g., 22.0 m of 11.7 g/t Au
including 4.0 m of 61.2 g/t Au, in hole CZ97-008
1
) intersected in previous drill programs to the south
(Figure 1).
The upper interval in CZ-25-021 contains multiple high-grade veins and breccias (
155.0 g/t gold over
1.0-meter, 101.0 g/t gold over 1.0 meter, and 30.6 g/t gold over 1.3 meters,
Table 1) within the
broad zone of disseminated gold mineralization (Figure 4). Similar to CZ-25-007, many of these higher-
grade intervals contain fine visible gold (Figure 4). The numerous high-grade veins intersected in many
holes near CZ-25-021 (e.g., JD-97-008, CZ-24-004, CZ-24-005. CZ-25-007, CZ-25-008) support the
strong, high-grade potential of the Creek Zone and validate the newly developed structural model.

Southeast Extension
Drill holes CZ-25-008, 009, 010, 011, 012, 013, 014, 015, 016 and 017 tested the southeastern extent of
bulk-tonnage and high-grade gold mineralization along the Creek Zone structural corridor. All holes
intersected gold mineralization and demonstrated a northwest, structurally controlled zone measuring at
least 750 meters by 300 meters and approximately 150 meters vertical. This mineralized corridor is
open for expansion along strike and down-dip (Figure 1 and 2). Management believes that further drilling
is warranted to test for parallel mineralized structures to the north and up-dip of hole CZ-25-017 (Figure
1).
Drill hole CZ-25-016 intersected 17.0 meters of 2.32 g/t gold from 308.5 meters downhole including 13.5
meters of 2.85 g/t Au (Figures 1 and 2 and Table 2). This interval is approximately 460 meters southeast
of CZ-25-021 (Figures 1 and 2). Drill hole CZ-25-014 intersected a broad zone of near-surface gold
mineralization, 64.0 meters of 0.60 g/t gold including 11.0 meters of 1.23 g/t gold from 47 meters
downhole. This interval is approximately 120 meters from CZ-25-021. Holes CZ-25-016, CZ-25-014 and
all holes along the structural corridor highlight the significant scale potential of the Creek Zone (Figures 1
and 2).
Structural Model
Orientated drill core data from 2024 and 2025, geological mapping and historical drill data were
incorporated into the first-ever 3D geological and structural model of the Creek Zone to guide
exploration drilling. Two distinct fault sets appear in the drill core and surface mapping: ~295-300° trend
and 315-320° trend both dipping ~50°. Intersections of these two fault sets appears to be a major control
on mineralization with vein-oriented core data suggesting an assemblage of individual NW striking,
steeply dipping veins. Taken together the Creek Zone represents a simple shear deformation zone with
secondary and antithetic mineralized fractures and structural intersections that produced mineralization
pathways and the formation of the high-grade gold veins and vein-breccias intercepted in drill holes
clustered around holes CZ-25-007 and CZ-25-021.
Management believes that additional drilling along the entire Creek Zone structural corridor is warranted
to test for these north-plunging zones of higher-grade mineralization along fault-intersections which may
have been missed in previous drill programs due the orientations of many of the historic drill holes.
Creek Zone Geology
All drill holes across the Creek Zone intersected a bedded sequence of intermediate volcanic and
volcaniclastic rocks re-interpreted from 2025 mapping to be a sequence within the lower feldspar-
hornblende unit of the Metsantan Member of the Early Jurassic Toodoggone formation. Higher-grade
gold mineralization is hosted in epithermal-related and locally banded quartz-carbonate veins, veinlets
and sulfide-cemented breccias with locally strong potassium feldspar alteration halos (Figure 4). Vein-
hosted sulfides include pyrite, sphalerite, ± chalcopyrite and galena with some veins containing visible
gold. Bulk-tonnage mineralization is associated with selectively pervasive sericite-chlorite-hematite
alteration with disseminated pyrite, proximal to vein-associated potassic alteration (Figure 4).
Next Steps
A selection of samples from 2024 and 2025 drilling at the Creek Zone has been submitted to the ALS
Global analytical facility in North Vancouver, British Columbia for metallic screen fire assay to better
define the nature and grade of gold mineralization. The metallic screen method utilises a larger sample
and a tailored preparation procedure to systematically capture native gold, if present. These methods
yield a more robust analytical and statistical estimate of gold grade. Results from this metallic screen
study will be compared to the traditional fire assay data to define a statistical based workflow for
sampling and analyzing intervals with high-grade gold mineralization.
Assay results are pending for four holes drilled at the Finn Zone, located approximately 3.5 km east of
the Creek Zone, and two drill holes from the Belle South Porphyry Zone, located approximately 8.0
kilometers southeast from the Creek Zone.
