Snowline GOLD Discovers New Rirgs Target Near Its Valley Deposit and Provides 2025 Field Program Update

Exploration Programs

SNOWLINE GOLD DISCOVERS NEW RIRGS TARGET NEAR ITS VALLEY

DEPOSIT AND PROVIDES 2025 FIELD PROGRAM UPDATE

• New reduced-intrusion related gold system, “Celestic,” discovered at surface roughly

27 km from Valley and 5 km from existing heavy equipment winter trail

• Discovery highlighted by selective grab samples of up to 11.7 g/t Au and an outcrop

chip sample of 1.09 g/t Au over 4.0 m from zones of densely sheeted quartz veins

exposed at surface

• Snowline’s broader 2025 field program advancing ahead of schedule, with >11,000 m

drilled to date on three targets alongside an expanded development-focused program to

support future technical studies and permitting.

Vancouver, B.C., July 2, 2025: SNOWLINE GOLD CORP. (TSX-V: SGD) (US OTCQB:

SNWGF) (the “Company” or “ Snowline”) is pleased to announce discovery of a reduced -

intrusion related gold system (“RIRGS”) on its Cynthia Project, Yukon, roughly 27 km

southwest of its Valley gold deposit (“Valley”) on the adjacent Rogue Project (Figures 2 & 3).

The “ Celestic” target covers several zones of gold-bearing, densely sheeted quartz veins

exposed in a 4.5 x 3 km granodiorite intrusion. Selective grab samples of quartz vein material

returned up to 11.7 g/t Au, while a continuous 4.0 m chip sample across an exposed outcrop

returned 1.09 g/t Au (Figure 1). Subject to additional follow up, the Celestic target may see

initial drilling in 2025 as Snowline advances its largest field program to date.

“That we are still finding large, exposed, untested, and previously unknown reduced-intrusion

related gold systems near our flagship Valley deposit highlights the underexplored nature of

this prospective district,” said Scott Berdahl, CEO & Director of Sno wline. “I would like to

commend Snowline’s field teams for their ongoing work in advancing and expanding our

pipeline of regional targets on our 100%-owned, 3,600 km2 Yukon mineral claim position. We

are excited by the demonstrated fertility of this region as we continue to uncover compelling

new targets, and of course by the opportunity to test these targets for the very first time.”

2025 FIELD PROGRAM UPDATE

Drilling: Snowline’s 2025 drill program is proceeding ahead of schedule, with five drills

turning and over 11,000 m completed to date in 28 holes on three targets. Over 8,000 m of this

drilling has been completed around Valley, primarily as step-outs sampling previously untested

locations within the broader Valley intrusion and as infill drilling aimed at converting inferred

mineral resources to indicated mineral resources or higher. Roughly 2,500 m has been

completed at the Einarson Project’s Jupiter target. An additional 500 m has been completed as

part of a Phase I drill program on the Einarson Project’s Neptune target, the first ever drill

testing of a roughly 30 km zone of elevated to anomalous gold in talus fines and soils associated

with a regional -scale faulted anticline. Subsequent regional drilling will focus primarily on

RIRGS targets on the Rogue and Cynthia projects.

Valley Development: Snowline has expanded the scope of its 2025 field program to support

advancement of Valley towards a Prefeasibility Study and permitting. The expanded program

includes:

• Surficial mapping, test pitting, sonic drilling and passive seismic surveying to

characterize overburden around Valley and at potential infrastructure locations

• geotechnical drilling to improve understanding of pit constraints

• geochemical and metallurgical testing to inform processing refinements and

reclamation considerations

• hydrometric monitoring and hydrogeological testing to further characterize surface and

groundwater

• expanded wildlife surveying to inform permitting baselines, and

• LiDAR surveying across the broader project footprint to inform engineering work.

CELESTIC TARGET, CYNTHIA PROPERTY

The Celestic target is a newly discovered RIRGS with a Valley -type signature characterized

by quartz-sheeted veins hosted within a 4.5 x 3 km multiphase granodioritic intrusive. The

target covers at least five areas of densely sheeted quartz veins. It is located roughly 1 km and

3 km southwest of Snowline’s “Intersection” and “Sydney” targets on its Cynthia Project,

Yukon and 27 km southwest of Valley. The Plata winter trail, a potential future access route

for Valley in the Rogue Project Preliminary Economic Assessment 1, runs within 5 km of the

target.

Regional geochemical sampling shows elevated to anomalous gold and bismuth values in

stream sediments across multiple drainages originating from the intrusion. Follow -up

prospecting revealed multiple zones of sheeted quartz veins typical of RIRGS mineraliz ation,

including a 500 x 400 m area with vein densities >10/m, often with multiple orientations

present. Initial results are considered by the Company to be encouraging; of 74 samples taken,

14 returned >0.1 g/t Au, averaging 1.4 g/t Au . Continuous sampling yielded channel samples

of 4.0 meters at 1.09 g/t Au, together with selective samples of bismuthinite-bearing quartz

vein material assaying up to 11.7 g/t Au. The sheeted vein corridor, characterized by gold -

bismuth-tellurium-tungsten anomalies, is open in all directions.

sheeted veins occur over an area of at least 4 x 1.5 km within the broader corridor and remain open. Letters A-D denote photograph

locations in Figure 1 above. The Intersection target is located immediately northeast of the intrusion and has seen limited historical

(2010) drilling, but earlier prospecting efforts did not extend into the intrusion.

STOCK OPTIONS, DEFERRED SHARE UNITS AND RESTRICTED SHARE UNITS

Snowline also announces that it has granted a total of 300,000 stock options, 60,000 Deferred

Share Units ("DSUs"), and 150,000 Restricted Share Units ("RSUs") to certain employees and

a director pursuant to its Omnibus Incentive Plan.

The stock options have an exercise price of C$8.64, vest 20% each six months starting six

months from the grant date and expire after five years. The RSUs vest 100% in three years

from the grant date. The DSUs vest immediately upon grant and are payable u pon the holder

ceasing to be a director of the Company.

ABOUT SNOWLINE GOLD CORP.

Snowline Gold Corp. is a Yukon Territory focused gold exploration and development company

with mineral claim portfolio covering roughly 360,000 ha (3,600 km 2). The Company is

advancing its Valley gold deposit—a large, low -strip, near surface, >1 g/t Au bulk tonnage

gold system located in the easter n Yukon—while continuing regional exploration of

surrounding targets on the Rogue Project and the broader district in the highly prospective yet

underexplored Selwyn Basin.

Valley hosts an open mineral resource estimate of 7.94 million ounces gold at 1.21 g/t Au

Measured and Indicated and an additional 0.89 million ounces gold Inferred at 0.62 g/t Au, as

outlined in a May 15, 2025 news release2. Results of a preliminary economic analysis on Valley

suggest the potential for the deposit to support a long -life mining operation with a strong

production profile and low production costs, as outlined in a June 23, 2025 news release.

Snowline’s project portfolio sits within the prolific Tintina Gold Province, host to multiple

million-ounce-plus gold mines and deposits across the central Yukon and Alaska. The

Company’s comprehensive first-mover position and extensive exploration databas e provide a

distinct competitive advantage and a unique opportunity for investors to be part of multiple

discoveries, the advancement of a significant gold deposit, and the creation of a new gold

district.
