SNOWLINE GOLD DRILLS 6.0 GRAMS PER TONNE GOLD OVER 101.0 M IN BROADER INTERVAL OF 4.1 GRAMS PER TONNE GOLD OVER 244.9 M FROM SURFACE AT ITS VALLEY DEPOSIT, AND IDENTIFIES TWO NEW GOLD TARGETS

Snowline Gold Corp. has released additional analytical results from its 2024 Valley deposit drilling campaign on the Rogue project in Canada's Yukon Territory alongside updates on its regional exploration campaign. Hole V-24-078 returned some of the highest sustained grades seen at the deposit to date. Additional holes from Valley carry long intervals from surface in the southeastern part of the Valley deposit. Outside of Valley, Snowline's regional exploration team has discovered two promising new grassroots gold targets, Charlotte and Galatea, on the Rogue and Einarson projects, respectively. Drilling is continuing at Valley and on the Jupiter target, Einarson project, with assays pending for an additional 22,500 metres drilled to date.

• Hole V-24-078 returned 4.05 g/t (grams per tonne) Au over 244.9 m from surface, including 5.99 g/t Au over 101.0 m, emphasizing strong continuity of high-grade, near-surface gold mineralization at Snowline's Valley deposit, Rogue project.
• Charlotte target is a newly discovered reduced intrusion-related gold system on the Rogue project in and around an elongate 1.6-by-0.3-kilometre intrusion, with selective grab samples up to 28.4 g/t Au.
• Galatea target hosts a 1.3 km quartz-carbonate boulder train found along 12 km structural corridor between Jupiter and Avalanche Creek, Einarson project, with grab samples to 6.11 g/t Au.
• Assays pending for greater than 22,500 m across seven targets, with drilling continuing.

"The breadth, consistency and grade of near-surface gold mineralization at Valley continue to impress us," said Scott Berdahl, chief executive officer and director of Snowline. "V-24-078 has set another very high bar, carrying an average grade of over four grams per tonne gold over 244.9 metres from surface, with a sustained run of 101.0 m averaging 6.0 g/t Au, while holes from the southeast and northwest parts of the deposit show good near-surface continuity and grades.

"In addition, our regional exploration team continues to turn up exciting new prospects on our underexplored, greater-than-3,600-square-kilometre tenure, including a new reduced-intrusion related gold system. That we are still finding potentially significant new mineralized systems on surface in our fourth exploration season in this area is a testament to the scale and the fertility of the district."

Valley drilling, Rogue project

Drilling at the Rogue project's Valley deposit is continuing, with four drills now active on the deposit. To date, roughly 20,400 m have been drilled at Valley in 46 holes in 2024. Trace instances of visible gold and widespread sheeted quartz vein arrays have been observed both within and beyond the confines of the current, initial MRE for Valley. The company awaits full assay results from the continuing drill campaign to assess the significance of these observations and their impact on the MRE.

Hole V-24-078

Hole V-24-078 is collared within the Valley intrusion, from the pad site of V-24-076 (212.4 m at 1.11 g/t Au, including 66.9 m at 2.02 g/t Au from surface, see Snowline news release dated Aug. 29, 2024) but drilled in the opposite direction to test a void in drill data within the Valley deposit. The nearest previous holes are V-23-048 (265.2 m at 2.20 g/t Au, including 100.2 m at 3.28 g/t Au from surface, see Snowline news release dated Sept. 11, 2023), collared roughly 50 m to the north-northeast, and V-22-014 (285.2 m at 1.45 g/t Au, including 128.2 m at 2.48 g/t Au from surface, see Snowline news release dated Nov. 15, 2022), collared roughly 65 m to the east-southeast, with both previous holes drilled to the southwest and ending outside of the intrusion.

V-24-078 runs predominantly in the main, coarse-grained granodioritic phase of the Valley intrusion throughout its length. Quart vein densities are consistently moderate to high for the top of the hole, dropping off to low (less than four v/m (volt per metre)) for the remainder of the hole after a series of faults at approximately 230 m down hole.

The hole begins with a strong intersection of gold mineralization, averaging 4.05 g/t over the top 244.9 m from bedrock surface at 8.2 m down hole. Grades increase somewhat from 80.5 m downhole, averaging 5.99 g/t Au over the next 101.0 m, marking highest gold grade over a greater than 100 m interval seen at Valley to date (including when assays are capped at 10.0 g/t Au, for a capped interval grade of 5.49 g/t Au -- see Table 2). Below this highlight section, three separate but proximal intervals carry grades averaging between 0.28 and 0.39 g/t Au to the end of the hole at 407.0 m.

The results of this hole are expected to help upgrade and derisk relevant areas of the initial mineral resource estimate for Valley. The ultimate effect of this result will be quantified along with analytical results of all subsequent holes in an updated mineral resource estimate at a later time.

Exploration updates

Snowline currently has one drill rig active on the Jupiter target, and regional field teams advancing multiple additional targets. More than 8,900 m have been completed in regional drilling to date across six targets outside of Valley. Assays are still pending for roughly 7,000 m from these regional targets, namely: Aurelius (five holes) and Reid (one hole) on the Rogue project, Sydney (three holes) on the Cynthia project, and Jupiter (eight holes) and Avalanche Creek (two holes) on the Einarson project.

Charlotte target, Rogue project

Charlotte is a newly discovered reduced intrusion-related gold system (RIRGS) on the Rogue project, roughly 15 km southeast of Valley. The target covers a multiphase, elongate granodiorite pluton exposed across roughly 1.6 km by 300 m, roughly corresponding to a kilometre-scale resistive feature identified by aerial electromagnetic surveying, similar in scale and nature to the geophysical anomaly previously identified at Valley.

Multiple generations of quartz veins, including sheeted quartz-arsenopyrite veins, are present within and proximal to the intrusion at Charlotte. Of 95 rock grab samples collected from the target area, 25 returned greater than one g/t Au, averaging 4.49 g/t Au up to a maximum of 28.4 g/t Au. Such samples are selective in nature, but they nonetheless demonstrate gold fertility of this RIRGS across a large area. A program of soil and talus fine samples in contour soil lines has been completed in the target area, which will assist in future targeting. Analytical results for these samples are still pending.

Galatea target, Einarson project

Galatea is a new epizonal orogenic target on Snowline's 100-per-cent-owned Einarson project, located along the N-S (north-south) structural corridor between the Jupiter target (roughly seven km north) and Avalanche Creek (roughly five km south). At Galatea, a 1.3 km long float train of quartz carbonate vein material was observed along a stream drainage. Of 12 rock grab samples taken, six returned greater than one g/t Au, averaging 3.34 g/t Au with a maximum of 6.11 g/t Au. A follow-up soil sampling program consisting of seven contour lines totalling eight km will be completed to further delineate the mineralization. This new target demonstrates the fertility of this greater than 12 km structural corridor and the prospectivity of adjacent, parallel structures in the area.

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 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 down hole 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' 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. A total of 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 reanalyzed 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 less than 0.1 g/t Au and may include any highlight subsections thereof.

About Rogue

Snowline Gold's 100-per-cent-owned, flagship Rogue project, in Canada's Yukon Territory, covers a 60 by 30 km cluster of intrusions in the eastern Tombstone gold belt known as the Rogue plutonic complex.

Since its launch in 2021, Snowline has progressed the Rogue project's Valley target from a greenfield prospecting discovery to a significant bulk tonnage gold resource, with 4.05-million-ounce gold indicated mineral resource at 1.66 g/t Au and an additional 3.26 Moz inferred mineral resource at 1.25 g/t Au within a pit-shell constraint. The resource estimate numbers are supported by the recent technical report for Rogue, prepared in accordance with NI 43-101 standards, entitled "Rogue Gold Project: NI 43-101 Technical Report and Mineral Resource Estimate," authored by Heather Burrell, PGeo, Daniel J. Redmond, PGeo, and Steven C. Haggarty, PEng, with an effective date of May 15, 2024.

Exploration of the open Valley system is continuing. Valley is a reduced intrusion-related gold system (RIRGS), geologically similar to multimillion-ounce RIRGS deposits currently in production, like Kinross's Fort Knox mine in Alaska, but with substantially higher gold grades. Gold is associated with bismuthinite and telluride minerals hosted in sheeted quartz vein arrays within and along the margins of a one-kilometre-scale, mid-Cretaceous aged Mayo-series intrusion.

The Rogue project area hosts multiple intrusions similar to Valley along with widespread gold anomalism in stream sediment, soil and rock samples. Elsewhere, RIRGS deposits are known to occur in clusters. For these reasons, Snowline considers the Rogue project to have district-scale potential to host additional reduced intrusion-related gold systems.
