Vancouver, B.C., September 24, 2025: SNOWLINE GOLD CORP. (TSX-V: SGD) (OTCQB: SNWGF) (the “Company” or “Snowline”) is pleased to announce additional drill results from ongoing exploration at its Rogue and Einarson projects in the eastern Yukon Territory. Drilling at Jupiter, an orogenic gold discovery on Snowline’s 100%-owned Einarson Project, extends the known strike length of gold mineralization by roughly 550 m to 1.9 km (Figure 1). Drill results within a 500 m gap in previous drilling returned 6.82 g/t Au 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 (“Valley”), 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 ongoing 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.

Table 1 – Highlight summary of Snowline’s latest assay results; see Tables 2 (Jupiter) and 3 (Valley) for details. Note that the interval highlighted for hole V-25-131 includes multiple intervals as reported in Table 3 along with small (6-6.5 m) distances in between. *Interval widths reported.

“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, CEO & 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.”

Figure 1 – Long section of Jupiter target, Einarson Project, showing drill results along the main trend to date. Hole J-25-037 provides evidence for continuity of mineralization between previous holes, while hole J-25-039 extends the known strike length of the system by 550 m to 1.9 km. The system remains open in both directions and to depth, with additional instances of mineralized surface float located 5 km and 12 km south along the same trend.

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 NNW-SSE 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 (Figure 2). 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 (Figure 1). 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 (e.g. Figure 2).

VALLEY UPDATES, ROGUE PROJECT

Figure 3 – Plan map of the Valley intrusion showing all drilling to date, including results from the current six holes reported for Valley. Observations of visible gold in holes that have yet to receive analytical results are shown as yellow circles. Note that 2025 holes are plotted above previous results for clarity, regardless of relative depths. The outline of the Valley intrusion corresponds to its expression at surface.

Drilling: Over 18,500 m of drilling has been completed within and near Valley to date in 2025, and drilling is ongoing. 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 (Figure 3). 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 67.5m 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 (Figure 3, Table 3).

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 (0.5-10 cm) quartz veins, consistent with the RIRGS deposit model. This regional exploration campaign is ongoing, with assays pending. Target locations are shown in Figure 4.

QA/QC

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 m 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 pre-determined 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 ¼ core samples by splitting the ½ 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’ 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 >85% passing below 2 mm and split using a riffle splitter. 250 g splits were pulverized to >85% passing below 75 microns. 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 analysed for gold content by fire assay with an atomic absorption spectroscopy (AAS) finish on 30 g samples (BV code: FA430). Any sample returning >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 >5.0 m assaying entirely <0.1 g/t Au and may include any highlight subsections thereof.

SNOWLINE GOLD IDENTIFIES NEW GOLD ZONE NEAR ITS VALLEY DEPOSIT AND PROVIDES REGIONAL EXPLORATION UPDATE

August 7, 2025August 7, 2025

Drilling along the eastern edge of the Valley intrusion intersects sheeted quartz veins with trace amounts of visible gold along an open, 500 m area, with assays pending.
Initial assay results from 2025 program at Valley reveal broad zones of gold mineralization outside of current MRE.
Regional drilling provides evidence of widespread gold fertility across all five RIRGS targets drilled outside of Valley to date in 2025. Assays pending for 17,500 m overall, with drilling ongoing.
Outcropping sheeted quartz veins in granodiorite discovered at the Ramsey target, Rogue Project, roughly 22 km west of Valley.

Vancouver, B.C., August 7, 2025: SNOWLINE GOLD CORP. (TSX-V: SGD) (US OTCQB: SNWGF) (the “Company” or “Snowline”) is pleased to provide updates to its ongoing exploration and development programs in the eastern Yukon. At Valley, sheeted quartz veins with visible gold are present in drill holes within a newly discovered and still open zone potentially 500 x 100+ m along the eastern boundary of the local intrusion (Figure 1), several hundred metres east of the current limit of the Valley Mineral Resource Estimate (“MRE”)[1] (Figure 2). On the broader Rogue Project, of five additional reduced-intrusion related gold system (“RIRGS”) targets drilled outside of Valley so far in 2025, all have now encountered trace instances of visible gold. Assays are pending for all regional holes. In addition, surface exploration has discovered sheeted quartz vein mineralization in granodiorite at Snowline’s early stage “Ramsey” target, located at low elevations roughly 22 km west of Valley. To date, over 20,000 m have been drilled by the Company this year on the Rogue and Einarson projects, with drilling ongoing and assays pending for approximately 17,500 m.

“We have a lot to be excited about as initial assays come in for the 2025 drill season,” said Scott Berdahl, CEO & Director of Snowline. “Late last season, drillhole V-24-115 gave indications that the eastern margin of the Valley intrusion could host an additional zone of strong RIRGS mineralization. Our current drilling shows increased quartz vein densities towards this eastern margin, accompanied by trace amounts of visible gold, along a wide corridor that is well outside of our previous drilling. On the broader Rogue Project, additional RIRGS targets demonstrate widespread gold fertility through drilling and through ongoing surface exploration. We await analytical results to determine the significance of these initial results.

“I would like to commend Snowline’s field team on safe execution of such a rigorous exploration campaign to date in the midst of a busy and multi-faceted season. The various engineering and environmental studies thrown into the mix to advance our Valley deposit have not dampened the pace nor the enthusiasm of our team in getting out and taking big swings towards making additional discoveries across our prospective greenfield mineral property portfolio.”

VALLEY UPDATES, ROGUE PROJECT

Drilling: Over 11,500 m of drilling has been completed within and near the Valley deposit to date in 2025, and drilling is ongoing. 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.

Of note, a new zone of sheeted quartz veins has been identified along the previously untested eastern margin of the Valley intrusion, with abundant instances of trace visible gold observed within the veins (Figures 1, 2 and 3). 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.

In addition, the Company has received results from its first five holes at Valley to date. These holes, V-25-125 through 129, reveal broad zones of anomalous gold mineralization outside of the current Valley MRE and, where inside the existing block model, will serve to inform potential recategorization of Inferred Mineral Resources (Figure 1, Table 1).

Valley Development: A rigorous program of geotechnical, geochemical, surface, groundwater and environmental testing is ongoing at Valley and related sites to support advancement of a future PFS and permitting.

Figure 3 – V-25-143 drill core from 427.0 m to 443.5 m downhole. Light to intense sheeted quartz veins cut the Valley intrusion at multiple orientations, with varying alteration types around different veins. Similar mineralization occurs from roughly 326 to 443 m downhole, as well as in surrounding holes in an open, 500 m area along the eastern edge of the Valley intrusion which was previously assumed to be unmineralized. Vein thicknesses range from 5 mm to >5 cm. Minor bismuthinite and trace visible gold (denoted by orange flagging tape above the core) are present in the sheeted veins. Assays for this hole and others are pending.

Table 1 – Anomalous gold intervals in drillholes V-25-025 through V-25-129 from the Valley deposit.

REGIONAL UPDATES, ROGUE PROJECT

Over 4,300 m of drilling has been completed to date in 2025 on the Rogue Project outside of the Valley deposit, on five additional targets. Rare instances of trace visible gold have been encountered in drill core from all five targets, in small (0.5-10 cm) quartz veins, consistent with the RIRGS deposit model. This regional exploration campaign is ongoing, with assays pending for all targets. Target locations are shown in Figure 4, and examples of intrusive drill core from the Duke, JP and Aurelius targets are shown as Figures 5, 6 and 7 respectively.

Figure 4 – Project location map for Snowline Gold’s eastern Selwyn Basin projects: Rogue, Einarson, Ursa, Cynthia and Olympus, highlighting targets drilled to date during Snowline’s 2025 exploration campaign.

Duke Target

Figure 5 – DUK-25-003 drill core from 391.5 m to 400.3 m downhole. Mineralization at Duke includes disseminated acicular arsenopyrite within the intrusion and surrounding country rock. Minor bismuthinite and trace visible gold (denoted by orange flagging tape above the core) are present in the sheeted veins. Assays for this hole and all others from Duke are pending.

Duke is located roughly 11 km southeast of Valley. The host intrusion forms a 1.4 x 1.3 km multiphase stock. The full extent of the intrusion is not yet known. A north-south creek through the intrusion exposes similar outcrops with evidence of surface mineralization along a 3 km corridor.

The intrusion at Duke is characterized by porphyritic to equigranular granodiorites and diorites crosscut by multiple intrusive breccias that in all cases show quartz±sulphide veins with minor to trace bismuthinite, arsenopyrite, boulangerite, chalcopyrite, pyrrhotite, and tourmaline. Disseminated acicular arsenopyrite is also observed within the intrusive and country-rock volcanic units. Three sets of veins have been identified with distinct orientations. Three holes have been completed (1,331 m) in the first-ever drill testing of the target, with rare, trace instances of visible gold observed each hole. Assay results are pending for these holes.

JP Target:

Figure 6 – JP-25-001 drill core from 353.7 m to 362.0 m downhole. Shallow-dipping quartz veins cut megacrystic syenite, in some cases with thick white alteration selvages. Vein thicknesses range from 5 mm to >5 cm. Minor bismuthinite and trace visible gold (denoted by orange flagging tape above the core) are present in the sheeted veins. Assays for this hole and others from JP are pending.

JP is another RIRGS target that forms part of the Rogue Plutonic Complex. It is located 8 km southwest of Valley, and 8 km south of the Valley access route envisioned in the recent Rogue Project PEA. It is characterized by a NE-elongated 1.2 x 0.7 km megacrystic syenite crosscut by smaller granodioritic dykes.

Mineralization is hosted in sub-horizontal quartz-sulphide veins, with densities varying between 1 and 3 veins per meter. These veins contain traces to massive aggregates of arsenopyrite, bismuthinite, pyrite, and pyrrhotite. Three holes have been completed as part of the first ever drill campaign done on this target (1,456 m). Rare, trace instances of visible gold have been identified within quartz veins in each hole. Assays are pending for all holes at JP.

Aurelius Target:

Figure 7 – AU-25-007 drill core from 103.8 m to 117.1 m downhole. Light to moderate sheeted quartz veins cut a granodiorite intrusion, with varying alteration types around different veins and selective oxidation. The hole is the first at Aurelius to intersect an intrusive stock and was cut short by technical issues. Assays for this hole and one other at Aurelius are pending, with plans for an additional hole to further test mineralization within this intrusion.

Two holes have been drilled so far at Aurelius as part of a Phase II drill program (535 m), following up on Phase I drilling in 2024. Of note, hole AU-25-007 intersected a medium-grained granodiorite containing sheeted quartz veins with varying levels of sulphides. Outcrops of similar granodiorite were identified 150 m south of this hole, but no veining was identified at surface. While trace visible gold was encountered in Phase I drilling, no visible gold has been observed to date within the intrusion. Assays are pending for all Phase II holes at Aurelius.

AU-25-007 didn’t reach its target depth due to operational problems. The drilled bedrock interval (between 80 and 150 meters) contains two sets of veins, all of them with minor to trace pyrrhotite, pyrite, arsenopyrite, bismuthinite, and molybdenite. Vein density ranges between 2 to 5 veins per meter. A follow-up hole is planned before the end of the season to further test this newly-discovered instance of intrusion-hosted sheeted quartz veins.

Ramsey Target:

Figure 8 – Sheeted quartz veins in outcropping granodiorite at the Ramsey target, Rogue Project. The outcrop is the first instance of granodiorite exposed in bedrock encountered at Ramsey, which occupies a topographic low. For scale, the handle of the rock hammer on the right side of the image is roughly 50 cm long.

Surface prospecting and mapping at the Ramsey target has located outcropping sheeted quartz veins hosted in granodiorite. Owing to the covered nature of the target area, the character and extent of this quartz vein hosted mineralization and the granodiorite itself are not yet known. The outcrop has been channel sampled across its full 7 m width, with assays pending. On positive results, the Ramsey target may become a candidate for a late-season, Phase I drill program. Initial prospecting of the target area yielded visible gold in outcrop, hosted by thin, sheeted quartz veins through gabbro, with a selective grab sample returning 86.5 g/t Au (see Snowline news release dated May 2, 2024).

The Ramsey target is located 22 km west of Valley and roughly 4 km from the access corridor envisioned by the recent Rogue Project PEA. It has never been drill tested.

QA/QC

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 m 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 pre-determined 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 ¼ core samples by splitting the ½ 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’ preparatory facility in Whitehorse, Yukon. Sample preparation was completed in Whitehorse, with analyses completed in Vancouver.

ABOUT SNOWLINE GOLD CORP.

Valley hosts an open MRE of 7.94 million ounces gold at 1.21 g/t Au Measured & 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)[1], 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 NI 43-101 standards, entitled “Independent Preliminary Economic Assessment for the Rogue Project Yukon, Canada,” dated July 30, 2025, with an effective date of March 1, 2025, and available on SEDAR+ and the Company’s website.

SNOWLINE GOLD FILES PRELIMINARY ECONOMIC ASSESSMENT REPORT FOR ITS VALLEY GOLD DEPOSIT, ROGUE PROJECT, YUKON

July 31, 2025July 31, 2025

Vancouver, B.C., July 31, 2025: SNOWLINE GOLD CORP. (TSX-V: SGD) (US OTCQB: SNWGF) (the “Company” or “Snowline”) is pleased to announce the filing on SEDAR+ of a technical report supporting the Preliminary Economic Assessment (“PEA” ) for its Valley gold deposit (“Valley”) on its 100%-owned Rogue Project in Canada’s Yukon Territory (“the Technical Report”).

The PEA is a conceptual study of the potential economic viability of Valley’s mineral resources and the first economic assessment of any kind on the broader Rogue Project. Results of the PEA were disclosed by the Company in a June 23, 2025 news release.

The PEA[i] envisions a conventional open pit mining and milling operation for Valley with a projected 20-year LOM producing 6.8 million ounces (Moz) of payable gold with a front-weighted production profile and attractive economic parameters. It demonstrates a C$3.37 billion post-tax net present value at a 5% discount rate (NPV5%) at US$2,150/oz Au, increasing to C$6.80 billion at US$3,150/oz Au[ii], and 544 koz annual average Au production at all in sustaining costs (“AISC”)[iii] of US$569/oz[iv] Au for the first five (5) full years of production. Full details of the PEA are available in the Technical Report, available under the Company’s profile at www.sedarplus.com and available on the Company’s website at www.snowlinegold.com .

The Rogue Project and broader infrastructure work considered by the PEA overlaps with Traditional Territories of the First Nation of Na-Cho Nyäk Dun, the Ross River Dena Council and Kaska Nation.

2025 FIELD PROGRAM UPDATE

The primary objective of Snowline’s 2025 field campaign is efficient, rapid advancement of Valley to support a Pre-Feasibility Study (“PFS”) and project permitting. Work currently underway includes geotechnical drilling (+3,000 m) and sonic drilling, engineering studies, and expanded environmental monitoring. Complementing this is 15,000 m of exploration drilling at Valley planned to support resource expansion and conversion.

Snowline also remains committed to regional exploration at our earlier-stage Yukon projects, with the goal of establishing a gold district in the target-rich environment surrounding Valley. 10,000 m of first pass and follow up drilling is underway, with seven targets across the Rogue (outside of Valley) and Einarson projects drilled to date. Extensive regional surface exploration and geophysical surveying will complement drilling efforts while advancing the numerous targets within Snowline’s exploration pipeline.

To date, approximately 18,500 m have been drilled this season. Initial drill results from the 2025 drill season are forthcoming.

USE OF NON-GAAP MEASURES

Certain financial measures referred to in this news release are not measures recognized under IFRS and are referred to as non-GAAP financial measures or ratios. These measures have no standardized meaning under IFRS and may not be comparable to similar measures presented by other companies. The definitions established and calculations performed by Snowline are based on management’s reasonable judgement and are consistently applied. These measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS.

The non-GAAP financial measures used in this news release and common to the gold mining industry are all-in sustaining cost per ounce of gold sold and free cash flow.

All-in sustaining cost per ounce of gold sold and free cash flow are non-GAAP financial measures or ratios and have no standardized meaning under IFRS Accounting Standards (“IFRS”) and may not be comparable to similar measures used by other issuers. As Valley is not in production, the Company does not have historical non-GAAP financial measures nor historical comparable measures under IFRS, and therefore the foregoing prospective non-GAAP financial measures or ratios may not be reconciled to the nearest comparable measures under IFRS.

END NOTES
[i] The PEA is preliminary in nature and includes inferred mineral resources (approximately 5% of total mineral resources) that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the PEA will be realized. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by Metal Prices, Economic Factors, Environmental, Permitting, Legal, Title, or other relevant issues.

[ii] Sensitivities apply to the financial model only; pit selection, cut-off grade and processing schedules remain based on a US$1,950/oz gold price and would likely be redesigned to optimize for significantly higher or significantly lower gold price scenarios.

[iii] AISC are the sum of operating costs, off-site costs, 1% NSR payments, sustaining capital costs and progressive reclamation costs (C$13M), divided by payable gold ounces produced. AISC excludes closure costs and any post-closure costs. Refer to the “Non-GAAP Financial Measures” section of this news release for more information.

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

July 2, 2025July 2, 2025

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 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%-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 , runs within 5 km of the target.

Figure 1 – Site photos from Celestic, with locations A-D shown in Figure 2 below. A) 11.7 g/t quartz-carbonate vein specimen with associated bismuthinite. B-D) Outcrops of densely sheeted veins, with multiple overlapping vein orientations. A chip sample denoted by the red line across outcrop B (total length: 4.0 m) returned 1.09 g/t.

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 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.

Figure 2 – Overview map of the Celestic target, located within a mid-Cretaceous aged granodiorite intrusion. Zones of densely 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.
