Sun Summit Confirms the High-Grade Gold-

Silver Potential of the Finn Zone: Drills 5.30 g/t

Gold and 157.9 g/t Silver over 6.0 meters at the

JD Project

Vancouver, British Columbia--(Newsfile Corp. - January 22, 2026) - Sun Summit Minerals Corp. (TSXV:

SMN) (OTCQB: SMREF) (

"Sun Summit"

or the

"Company"

) is pleased to report assay results from

all 2025 drilling at the Finn Zone of its JD Project in the Toodoggone Mining District, north-central British

Columbia. 2025 drill results will be integrated into an updated 3D model and will inform the fully funded

10,000 meter drill program planned for 2026.

Drill hole FZ-25-002 returned a significant interval of near-surface gold-silver mineralization: 46.0 meters

of 1.03 g/t gold with 44.9 g/t silver from 38.0 meters down hole, including

6.0 meters of 5.30 g/t gold

with 157.9 g/t silver

from 60.0 meters down hole. This interval is punctuated with a 1.0-meter zone that

returned

784.0 g/t silver

, highlighting the high-grade and historically overlooked silver potential of the

Finn zone epithermal-related system.

Highlights:

Drill hole FZ-25-002 investigated the gold-silver mineralization potential of the Finn Zone and

evaluated the structural controls on the high-grade silver component.

The drill hole intersected a

broad zone of near-surface gold-silver mineralization punctuated with high-grade gold

and silver veins and hydrothermal breccias:

46.0 meters of 1.03 g/t gold with 44.9 g/t silver from 38.0 meters downhole, including

17.0 meters of 2.31 g/t gold with 113.1 g/t silver

from 49.0 meters downhole, and

including

6.0 meters of 5.30 g/t gold with 157.9 g/t silver

from 60.0 meters downhole

high-grade gold-silver intercepts of:

447 g/t silver

with 0.93 g/t gold over 1.0 meter at 53.0 meters down hole

19.75 g/t gold

with 80.90 g/t silver over 1.0 meter at 60.0 meters down hole

784 g/t silver

with 6.79 g/t gold over 1.0 meter at 65.0 meters down hole

Confirms the strong high-grade gold-silver potential of the Finn Zone:

Numerous high-

grade intercepts in drill holes FZ-25-002 and FZ-25-001 (e.g.,

273 g/t silver with 2.6 g/t gold

over 0.51 meters at 38.3 meters downhole and 22.9 g/t gold with 29.0 g/t silver over 0.50 meters at

65.0 meters downhole, (Table 1) demonstrate the high-grade potential of the target. Additional

drilling and modelling focused on the structural controls on the silver-rich zones are planned for

follow-up drill programs.

Strong gold-silver mineralization intersected in FZ-25-004 confirms the expansion

potential of the Finn Zone down-dip.

The drill hole investigated the down-dip extent of bulk-

tonnage style mineralization of the Finn Zone and intersected multiple zones of mineralization

including a strong interval of gold-silver mineralization approximately 160 meters down-dip from

FZ-25-002 (

15.8 meters of 1.17 g/t gold with 9.12 g/t silver

from 104.0 meters downhole,

including

7.0 meters of 1.72 g/t gold with 15.3 g/t silver

from 111.0 meters downhole).

Strong porphyry-related alteration intersected in two reconnaissance drill holes at the

Belle South target:

Zones of intense phyllic and local potassic alteration overprinting polymictic

breccias suggest proximity to a robust porphyry-copper system. The +8.5 km trend of significant

hydrothermal alteration coincident with IP and magnetic anomalies is considered strongly

prospective for porphyry-related mineralization. Significant exploration across the JD Porphyry

trend is planned for 2026.

Planning underway for a significant fully funded 2026 drill program at the JD Project:

Drilling in 2026 at JD will focus on the evaluating the lateral and vertical extents of the Creek Zone

(e.g.,

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

, and

81.0 meters of 4.8 g/t gold including 14.0 meters of 19.81 g/t

gold

, see news release dated

November 25

th

, 2025

) and the Finn Zone and additional high-

priority targets along the Creek to Finn Corridor (Figure 1). Results from the 2026 drill program will

contribute to an inaugural mineral resource estimate.

"Results from our late-season, modest, four drill hole program at the Finn Zone in 2025 have exceeded

expectations and firmly establish the zone as a high-priority target for significant drilling in 2026. The

presence of both high-grade and near-surface bulk-tonnage style gold-silver mineralization with strong

continuity positions the target as an area for significant drilling in 2026," said Niel Marotta, CEO of Sun

Summit Minerals. "We are fortunate to have growing institutional investor support and Sun Summit is fully

funded for its 2026 drill program after closing an oversubscribed $11.5 million private placement in

December 2025. Planning is underway for a considerable follow-up resource-focused drill program, with

a minimum 10,000 meters of drilling expected. The 2026 program would exceed the 9,400 meters of

cumulative drilling completed by Sun Summit in 2024 and 2025, and further adds to the 36,000 meters of

historic drilling at JD prior to 2024. The focus of the 2026 drill program will be at the Creek to Finn

Corridor, and drill results will contribute to an inaugural mineral resource estimate expected by Q2

2027."

2025 Finn Zone Drill Program

Four drill holes, totalling 950 meters were completed at the Finn Zone in 2025 (Figure 2 and Table 2).

The epithermal-related, gold-silver zone is approximately 3.5 kilometers east of the Creek Zone (e.g.,

81.0 meters of 4.8 g/t gold, see November 25

th

, 2025 news release) and marks the eastern extent of the

highly-prospective 4.5 kilometer long, Creek to Finn corridor (Figure 1). The drill holes were designed to

investigate the continuity of near-surface, high-grade gold-silver mineralization and the down-dip extent

of bulk-tonnage mineralization intersected in previous drill programs (e.g.,

35.7 meters of 7.26 g/t gold,

94 g/t silver including 1.0 meters of 215.4 g/t gold, 308 g/t silver in JD95-047

2

and 20.85 meters

of 8.76 g/t gold, 68 g/t silver including 11.0 m of 15.1 g/t gold,108 g/t silver in JD95-097

2

,

Figure

2). Extensive modelling of compiled historical Finn zone drill data outlined a compelling zone of strong

silver-rich mineralization (e.g., 45.0 m of 3.02 g/t Au, 136 g/t Ag including

5.0 meters of 8.18 g/t gold,

918 g/t silver in JD95-076

2

). Drilling in 2025 also focused on evaluating the structural and/or lithological

controls on this gold-associated, silver-rich mineralization.

Highlights from 2025 Finn Zone Drilling include:

Drill holes FZ-25-001 and FZ-25-002 successfully confirmed the near-surface bulk-tonnage and the

high-grade gold-silver potential of the Finn Zone. Drill hole FZ-25-002 intersected a broad zone of

near-surface gold-silver mineralization punctuated with high-grade gold and silver veins and

hydrothermal breccias (e.g., 46.0 meters of 1.03 g/t gold with 44.9 g/t silver from 38.0 meters

downhole, including

,

17.0 meters of 2.31 g/t gold with 113.1 g/t silver, Figure 2 and Table 1). The

main interval consists of numerous, local high-grade veins and breccias (e.g., 447 g/t silver with

0.93 g/t gold over 1.0 meter, 19.75 g/t gold with 80.90 g/t silver over 1.0 meter and 784 g/t silver

with 6.79 g/t gold over 1.0 meter). Based on gold-silver ratios it appears the high-silver domains

represent a different pulse of mineralization. Further modelling and follow-up drilling is required to

define the extents of this high-silver domain.

Drill holes FZ-25-003 and FZ-25-004 were step-out holes designed to test the dip-extent of

mineralization along the gently north-dipping zone of volcanic breccias (Figure 3). Drill hole FZ-25-

004 intersected multiple zones of gold-silver mineralization (e.g., 15.8 meters of 1.17 g/t gold with

9.12 g/t silver, including 7.0 meters of 1.72 g/t gold with 15.30 g/t silver, Figure 3, Table 1) typical

of the core of the Finn Zone. This zone of strong mineralization in FZ-25-004 is approximately 160

meters downdip from FZ-25-002 (Figure 3). Mineralization intersected in FZ-25-004 confirms the

expansion potential of the Finn Zone down-dip.

Finn Zone Geology

Most of the historical drilling (over 300 drill holes) at the JD Project was focused on the Finn zone where

a broad zone of near-surface, epithermal-related gold-silver mineralization was defined (Figure 1).

Mineralization is primarily hosted in the hanging wall of a gently north-dipping, northeast-striking, locally

faulted volcaniclastic unit. The volcaniclastic unit, traced for over 1.5 kilometres along strike to the west

from the Finn zone, separates two andesite-dominant lithological units of the Toodoggone Formation

(Metsantan and McClair members). Faulting and subsequent mineralization likely exploited a

volcaniclastic unit, at the base of the Metsantan member, where epithermal-related fluids were focused

along permeable volcanic breccias.

The core of the Finn zone consists of strongly silica+clay+sericite altered polymictic breccias, locally

cemented with quartz and mineralized with pyrite with lesser sphalerite, galena, and chalcopyrite.

Peripheral to the high-grade core, epithermal-related alteration grades into sericite+chlorite+pyrite and

more distal epidote+chlorite+/-hematite assemblages with elevated base-metal mineralization.

Next Steps: Creek to Finn Corridor

Assay and geological data from the 2025 Finn Zone drill program are currently being integrated into an

updated 3D structural and mineralization model for the target area. The results from the modelling will

inform the next phase of drilling set to commence this summer.

The focus of the significant drill program at the 4.5 km Creek to Finn Corridor will be on targeting the

extents of mineralization at the Creek and Finn zones. Drill results will contribute to an inaugural mineral

resource estimate. Details of the summer 2026 JD drill program will be announced once plans and

budgets are set.

Belle South Porphyry Target

Two drill holes for 811 meters in 2025 evaluated the recently defined and previously untested Belle South

Porphyry target (see

September 18

th

, 2025

news release, Figure 5). The two drill holes focused on

coincident magnetic-high and high-chargeability anomalies near the southern extent of the McClair

Creek alteration zone (Figure 5). The purpose of the two short holes was to test for porphyry-related

alteration and mineralization in an area largely covered by till.

The first hole, JD-25-013, collared in rubbly and pervasively QSP (quartz-sericite-pyrite, phyllic

assemblage) altered andesite which transitioned to a broad zone of intermediate volcaniclastic rocks

(crystal to lapilli tuffs) to bottom of hole. The breccias are locally potassic (potassium feldspar-magnetite)

altered and cut by zones of intense phyllic alteration (Figure 6). The breccias locally contain altered

intrusive clasts and intervals with hydrothermal magnetite cement (Figure 6). Phyllic alteration with strong

disseminated pyrite (up to 20%) persisted throughout the hole with an increase in argillic assemblages

with possible gusano textures near the bottom of the hole.

Drill hole JD-25-014 tested the core of the magnetic-high and collared in porphyritic quartz monzodiorite

with increasing propylitic (epidote-chlorite) alteration with local pervasive potassium feldspar alteration

to bottom of hole. The monzodiorite is weakly to moderately magnetic.

The lithologies and alteration assemblages intersected in both holes suggest proximity to a porphyry-

related copper system. The holes returned weakly anomalous zones of copper mineralization with

geochemical data suggesting the holes intersected distal alteration assemblages (e.g., elevated zinc).

The two holes tested only a small portion of the 8.5 km by 2 km long JD Porphyry trend. Only five drill

holes have previously investigated the porphyry-copper potential of the trend, all focused 5 km north at

the McClair target near the epithermal-related Finn Zone (see

February 5

th

, 2025

news releases).

Similar to the McClair target, the Belle South target warrants significantly more drilling to fully evaluate

the porphyry potential of the compelling target area.

Details of the 2026 porphyry-focused exploration program at JD will be announced once all surface data

(e.g., rock and soil geochemistry and hyperspectral) have been interpreted together with all geophysical

data-sets (e.g., IP, magnetics).

A program of continued geophysical surveys, geological mapping and

drilling is anticipated.
