SNOWLINE GOLD DISCOVERS NEW RIRGS TARGET NEAR ITS VALLEY DEPOSIT AND PROVIDES 2025 FIELD PROGRAM UPDATE

Snowline Gold Corp. has discovered a reduced intrusion-related gold system (RIRGS) on its Cynthia project in Yukon, roughly 27 kilometres southwest of its Valley gold deposit on the adjacent Rogue project. The Celestic target covers several zones of gold-bearing, densely sheeted quartz veins exposed in a 4.5-kilometre-by-three-kilometre granodiorite intrusion. Selective grab samples of quartz vein material returned up to 11.7 grams per tonne gold while a continuous 4.0-metre chip sample across an exposed outcrop returned 1.09 grams per tonne gold. 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, chief executive officer and a director of Snowline. "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-per-cent-owned, 3,600-square-kilometre 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 metres completed to date in 28 holes on three targets. Over 8,000 metres of this drilling have been completed around Valley, primarily as stepouts 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 metres have been completed at the Einarson project's Jupiter target. An additional 500 metres have 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-kilometre 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 toward 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;
• 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-kilometre-by-three-kilometre multiphase granodioritic intrusive. The target covers at least five areas of densely sheeted quartz veins. It is located roughly one kilometre and three kilometres southwest of Snowline's Intersection and Sydney targets on its Cynthia project in Yukon and 27 kilometres southwest of Valley. The Plata winter trail, a potential future access route for Valley in the Rogue project preliminary economic assessment, runs within five kilometres 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 mineralization, including a 500-metre-by-400-metre area with vein densities greater than 10 per metre, often with multiple orientations present. Initial results are considered by the company to be encouraging; of 74 samples taken, 14 returned greater than 0.1 gram per tonne gold, averaging 1.4 grams per tonne gold. Continuous sampling yielded channel samples of 4.0 metres at 1.09 grams per tonne gold, together with selective samples of bismuthinite-bearing quartz vein material assaying up to 11.7 grams per tonne gold. The sheeted vein corridor, characterized by gold-bismuth-tellurium-tungsten anomalies, is open in all directions.

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 $8.64, vest 20 per cent every six months starting six months from the grant date and expire after five years. The RSUs vest 100 per cent in three years from the grant date. The DSUs vest immediately upon grant and are payable upon the holder ceasing to be a director of the company.

About Snowline Gold Corp.

Snowline Gold is a Yukon-focused gold exploration and development company with mineral claim portfolio covering roughly 360,000 hectares (3,600 square kilometres). The company is advancing its Valley gold deposit -- a large, low-strip, near-surface, greater-than-one-gram-per-tonne-gold bulk-tonnage gold system located in eastern 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 measured and indicated at 1.21 grams per tonne gold and an additional 890,000 ounces gold inferred at 0.62 gram per tonne gold, as outlined in a May 15, 2025, news release. 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 central Yukon and Alaska. The company's comprehensive first-mover position and extensive exploration database 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.
