SNOWLINE GOLD EXTENDS STRIKE LENGTH BY 550 M AND INTERSECTS 6.8 GRAMS PER TONNE GOLD OVER 9.0 M AT ITS JUPITER TARGET, EINARSON PROJECT, YUKON

Snowline Gold Corp. has released additional drill results from continuing exploration at its Rogue and Einarson projects in the eastern Yukon Territory. Drilling at Jupiter, an orogenic gold discovery on Snowline's 100-per-cent-owned Einarson project, extends the known strike length of gold mineralization by roughly 550 metres to 1.9 kilometres. Drill results within a 500 m gap in previous drilling returned 6.82 grams per tonne Au (gold) over 9.0 m from 179.5 m downhole in hole J-25-037. The gold system at Jupiter remains open along strike in both directions and to depth. At Snowline's flagship Valley gold deposit on the Rogue project, infill and expansion drilling continue to confirm and expand the scale of known mineralization. To date, over 28,500 m have been drilled by the company this year on the Rogue and Einarson projects, with drilling continuing and assays pending for approximately 20,000 m. The 2025 exploration program is complemented by extensive engineering and environmental fieldwork at Valley to inform future studies and permitting efforts.

"We are in the early days of exploring the large orogenic gold system at Jupiter, on our Einarson project, and the results demonstrate significant potential," said Scott Berdahl, chief executive officer and director of Snowline. "With a thin blanket of transported glacial till covering the deposit, our consistent success in intersecting thick zones of gold mineralization across a large footprint is a strong sign of the system's potential quality and scale. While Jupiter has been overshadowed by our flagship Valley discovery some 30 km away, it has hallmarks of a stand-alone project. And, importantly, Jupiter represents a different style of gold mineralization than Valley, highlighting the general fertility of this underexplored part of the Selwyn basin."

Jupiter target, Einarson project

Jupiter is an epizonal orogenic gold discovery roughly 30 km north of Valley. Of the six holes reported herein, three were drilled within the main north-northwest-south-southeast corridor where mineralization has been encountered to date. Two of these holes were drilled in large untested gaps in previous drilling, with hole J-25-037 intersecting a highlight interval of 6.82 g/t Au over 9.0 m. The third such hole, J-25-039, was collared roughly 440 m north of previous holes and considerably expands the footprint of known mineralization at Jupiter which now extends roughly 1.9 km. The gold system at Jupiter remains open along strike and to depth.

The mineralized intervals in holes J-25-037 and J-25-039 are related to strongly deformed quartz-carbonate veins formed along a district-scale, locally repeated thrust fault system between two siliciclastic sedimentary rock units.

Valley updates, Rogue project

Drilling: Over 18,500 m of drilling has been completed within and near Valley to date in 2025, and drilling is continuing. The objectives of this program are: 1) to test potential expansion of the current MRE for Valley; 2) to test for new zones of high-grade mineralization within the Valley intrusion; and 3) to prepare for a future prefeasibility study (PFS) by upgrading inferred resources to higher categories and obtaining additional geotechnical information.

Drilling along the northeastern margin of the Valley intrusion continues to intersect low to moderate quartz vein densities frequently containing trace instances of visible gold. The location of this mineralization at depth corresponds to the surface expression of the Ridge zone soil and talus fine gold anomaly, identified by the company in early sampling (see Snowline's March 10, 2022, news release). These observations await analytical results, which are necessary to assess the significance of the new zone of mineralization.

The company has received results from six additional holes at Valley. These holes, V-25-130 through 135, continue to encounter broad zones of anomalous gold mineralization outside of the current Valley MRE and PEA mine plan. Hole V-25-132, for example, returned 209.0 m at 0.45 g/t Au, including 67.5 m at 0.88 g/t Au, roughly 70 m southeast of the PEA mine plan. Where inside the existing block model, results will serve to inform potential recategorization of inferred mineral resources.

Valley development: A rigorous program of geotechnical, geochemical, surface, groundwater and environmental testing continues at Valley. Details and accomplishments of this program will be outlined in a future release.

Regional updates, Rogue project

Roughly 6,280 m of drilling has been completed to date in 2025 on the Rogue project outside of Valley, on seven additional targets. Rare instances of trace visible gold have been encountered in drill core from all seven targets in surface sampling or drilling, in small (0.5- to 10-centimetre) quartz veins, consistent with the RIRGS deposit model. This regional exploration campaign is continuing, with assays pending.

QA/QC (quality assurance/quality control)

On receipt from the drill site NQ2-sized drill core was systematically logged for geological attributes, photographed and sampled at Snowline's Forks camp. Sample lengths as small as 0.5 metre were used to isolate features of interest, but most samples within moderate to strong mineralization were 1.0 m in length; otherwise, a default 1.5 m downhole sample length was used. Core was cut in half lengthwise along a predetermined line, with one-half (same half, consistently, dictated by orientation line where present or by dominant vein orientation where absent) collected for analysis and one-half stored as a record. Field duplicates were collected at regular intervals as one-fourth core samples by splitting the one-half core sent for sampling, leaving a consistent record of half core material from duplicate and non-duplicate samples alike. Standard reference materials and blanks were inserted by Snowline personnel at regular intervals into the sample stream. Bagged samples were sealed with security tags to ensure integrity during transport. They were delivered by expeditor to Bureau Veritas's preparatory facility in Whitehorse, Yukon. Sample preparation was completed in Whitehorse, with analyses completed in Vancouver.

Bureau Veritas is accredited to ISO/IEC 17025 and ISO9001 for quality management. Samples were crushed by BV to greater than 85 per cent passing below two millimetres and split using a riffle splitter. And 250 g splits were pulverized to greater than 85 per cent passing below 75 micrometres. A four-acid digest with an inductively coupled plasma mass spectroscopy (ICP-MS) finish was used for 59-element analysis on 0.25 g sample pulps (BV code: MA250). All samples were analyzed for gold content by fire assay with an atomic absorption spectroscopy (AAS) finish on 30 g samples (BV code: FA430). Any sample returning greater than 10 g/t Au was reanalysed by fire assay with a gravimetric finish on a 30 g sample (BV code: FA530).

For the purposes of this release, contiguous mineralized intervals at Valley are defined as runs of mineralization with no break greater than 5.0 m assaying entirely less than 0.1 g/t Au and may include any highlight subsections thereof.

About Snowline Gold Corp.

Snowline Gold is a Yukon Territory-focused gold exploration and development company with mineral claim portfolio covering roughly 360,000 hectares (3,600 square km). The company is advancing its Valley gold deposit -- a large, low-strip, near-surface, greater than one g/t Au bulk-tonnage gold system located in the 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 MRE of 7.94 million ounces gold at 1.21 g/t Au measured and indicated (in 204.0 million tonnes) and an additional 0.89 million ounces gold inferred at 0.62 g/t Au (in 44.5 million tonnes), with a cut-off grade of 0.3 g/t Au. Results of a preliminary economic assessment (PEA) of Valley suggest the potential for the deposit to support a long-life mining operation with a strong production profile and low production costs. The MRE and PEA are supported by the recent technical report for Rogue, prepared in accordance with National Instrument 43-101 standards, entitled "Independent Preliminary Economic Assessment for the Rogue Project Yukon, Canada," dated Aug. 27, 2025, with an effective date of March 1, 2025, and available on SEDAR+ and the company's website.

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 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.
