SNOWLINE GOLD DRILLS MINERALIZATION 300 M BEYOND CURRENT RESOURCE

IN EXPANSION DRILLING AT THE VALLEY DEPOSIT, ROGUE PROJECT, AND

DEMONSTRATES DISTRICT POTENTIAL WITH INTERSECTION OF 20.9 GRAMS PER

TONNE GOLD OVER 2.1 M AT ITS JUPITER TARGET, EINARSON PROJECT, YUKON

• Resource Expansion Potential at Valley: Hole V-24-115 intersects 2.08 g/t Au over

15.5 m within a broader 100.5 m intersection averaging 0.53 g/t Au, showing

strong mineralization in an unexplored part of the Valley intrusion over 300 m east of

the Valley deposit, Rogue Project

• Continuity Confirmed: Hole V-24-117 intersects 1.64 g/t Au over 112.5 m within a

broader 242.5 m intersection averaging 1.14 g/t Au, demonstrating strong

continuity of the Valley Deposit along with other infill holes

• District Potential Demonstrated: Einarson Project hole J-24-031 returns 20.94 g/t Au

over 2.1 m within 9.45 m of 6.81 g/t Au at the Jupiter target, expanding

mineralization 50 m to depth (open) and advancing understanding of structural

controls

• Drilling Update: Assays remain pending for >2,500 m from 6 holes from infill and

expansionary drilling at Snowline’s Valley deposit, Rogue Project.

Vancouver, B.C., February 19, 2025: SNOWLINE GOLD CORP (TSX-V: SGD) (OTC:

SNWGF) (the “Company” or “Snowline”) is pleased to announce further results from its 2024

drill campaign on the Valley deposit, Rogue Project, and from its Jupiter target on the adjacent

Einarson Project, Yukon. At Valley, holes V-24-114 and V-24-115 both returned intervals of

strong gold mineralization outside of the existing MRE, demonstrating the presence of gold

within a large and still untested part of the Valley intrusion. Additional holes V-24-116 and V-

24-117 show continuity of >1 g/t gold grades along multiple edges of the primary deposit area

at Valley. These results will help to inform an updated MRE for Valley anticipated in the

coming months. At Jupiter, roughly 30 km north of Valley on the adjacent Einarson Project,

three of four reported holes intersected >8 g/t Au mineralization, with an interval of 20.9 g/t

Au over 2.1 m ( ~true width) in J -24-031 confirming a secondary east -west structural control

on mineralization that could assist with future targeting at Jupiter and regionally. Results are

pending for an additional >2,500 m of drilling in six holes from infill and expansionary drilling

at the Valley deposit, Rogue Project.

“The near-surface, high-grade part of the Valley intrusion that hosts Snowline’s Valley gold

deposit rightfully commands a lot of attention, ” said Scott Berdahl, CEO & Director of

Snowline. “ Today’s results from other parts of the Valley intrusion and from the separate

Jupiter target are both great reminders that the Valley deposit was not created in a vacuum, but

rather as a product of target-scale and regional-scale geological processes underpinned by gold

fertility of the eastern Selwyn Basin . Hole V -24-115 highlights the potential of the Valley

intrusion itself—outside of the current Valley deposit—to host additional zones of high-grade

gold mineralization. Roughly 30 km to the north, at our Jupiter target, the grades seen in J-24-

031 are encouraging and further enhance our understanding of th is structurally-controlled

system. Both results support Snowline’s founding conviction that a previously unrecognized

gold district could exist within our project boundaries in the eastern Yukon Territory.

“My congratulations go to Snowline’s team for the innovative, data - and observation-driven

thinking that led to these drill holes and today’s discoveries. We are excited to get back out

into the field in 2025 as we continue to advance these ideas and others throughout our robust,

district-scale project pipeline.”

VALLEY DRILLING, ROGUE PROJECT

The seven holes reported herein from Valley primarily target the margins of the known deposit

as well as untested areas beyond these margins (e.g. V -24-113, 114 & 115). The results

continue to build on the Company’s understanding of the Valley deposit through de -risking

and potential expansion.

Roughly 25,000 m were drilled at Valley in 55 holes in 2024 – nearly double the amount of

drilling (27,911 m) used to inform the Company’s initial MRE for Valley. The results of this

drilling will be used to produce an updated MRE on the Valley deposit in Q1 or Q2 of 2025,

as well as to inform future economic studies.

Hole V-24-112

Drilled as a 50 m step-out from V-22-015 along the eastern edge of the Valley deposit (Figure

1), V-24-112 intersected multiple mineralized intervals, including a 237.0 m length averaging

0.75 g/t Au from 147.5 m downhole (Table 2). This mineralization—at nearly double the 0.4

g/t Au mill cutoff grade used for the 2024 Valley MRE—expands the breadth of the company’s

understanding of the eastern edge of the Valley deposit.

Including non-mineralized intervals, V -24-112 averages 0.5 g/t Au over 599.9 m downhole

from bedrock surface at 11.1 m.

Hole V-24-113

V-24-113 is a 140 m step back along section from V-24-097 (Figure 2) and a 60 m step to the

north of V -23-038, testing mineralization at depth beyond what is currently the northeastern

edge of the Valley deposit. The strongest interval of mineralization averaged 0.50 g/t Au over

234.0 m from 207.5 m downhole, with this interval occurring entirely outside the limits of the

block model used to inform the 2024 MRE for Valley.

Hole V-24-114

Drilled towards the northwest, away from the eastern edge of the Valley deposit, V-24-114

encountered muted grades initially before intersecting 122.2 m averaging 0.47 g/t Au from 93.5

m downhole. Vein density and instances of visible gold increase with depth down the hole. The

and were assumed as nil for the initial Valley MRE.

hole ends in mineralization, with the final 10.5 m downhole averaging 1.35 g/t Au well outside

the Valley MRE, adjacent to on an open void in drill coverage (Figure 1).

Hole V-24-115

Like V-24-114, V-24-115 is also oriented northwest, drilled into a large volume of the Valley

intrusion that has seen little to no drill testing (Figure 1), crosscutting an east-west oriented

vein trend observed in this area. The hole hit multiple zones of mineralization, most notably a

100.5 m intersection averaging 0.53 g/t Au from 172.0 m downhole, with a 15.5 m downhole

intersection averaging 2.08 g/t Au.

Notably, the drill hole primarily encountered coarse -grained granodiorite—the host phase to

most of the mineralization in the Valley deposit —as opposed to a medium -grained phase

expected based on previous hole V-22-017 (collared from the same site but drilled southwest).

The 15.5 m interval of 2.08 g/t Au is associated with a dike of fine -grained porphyritic

granodiorite, which is thought to be a causative intrusive phase for the high grades seen in the

main part of the Valley deposit.

The hole ended in coarse-grained granodiorite and did not intersect the northeastern wall of the

Valley intrusion, which remains unconstrained at depth.

Hole V-24-116

V-24-116 infills a 130 m gap in section between V-23-041 and V-23-042, on the southeastern

side of the deposit. An interval of 287.8 m downhole averaging 0.95 g/t Au from bedrock

surface at 12.7 m downhole, including 145.0 m at 1.24 g/t Au from 77.0 m downhole, confirms

continuity of strong mineralization in this part of the Valley deposit.

Hole V-24-117

Collared outside of the Valley intrusion and drilled from west to east, V -24-117 encountered

sparse zones of mineralization in the hornfels zone followed by a broad zone of mineralization

on entering the Valley intrusion, returning 242.5 m at 1.14 g/t Au f rom 174.0 m downhole,

including 112.5 m at 1.64 g/t Au from 277.0 m downhole. This interval, which spans the edge

of the resource limiting pit-shell constraint for the 2024 Valley MRE, adds dimensionality to a

zone of mineralization encountered at depth in previous hole V-23-039.

Hole V-24-118

V-24-118 is among the southernmost holes drilled at Valley (Figure 1). The hole averages 0.71

g/t Au over the top 221.9 m from bedrock surface at 18.6 m downhole, with the bottom 59.0 m

of this interval occurring outside of the resource-limiting pit constraint used for the 2024 Valley

MRE.

pit shell. The block model has not been updated to reflect the current results, nor any results to date from 2024 (bold labels). Blocks shown outside

of the current pit shell constraint are not included in the initial MRE for Valley. Areas without blocks have not been modelled and were assumed as

nil for the initial Valley MRE. Instances of visible gold in holes still awaiting assay results are marked by yellow spheres.

Table 2 – Summary of significant mineralization returned from current holes from Valley . The consistency of strong

mineralization in the Valley deposit is reinforced by the capped values in the rightmost column, wherein any assay result >10

g/t Au is replaced by 10.0 g/t Au to calculate the average interval grades. Rounding errors may be present in interval lengths.

*Interval widths reported; true widths of the Valley system are complex, with different vein generations, orientations, and

grade distributions present within various intervals through the bulk tonnage gold target at Valley.

JUPITER DRILLING, EINARSON PROJECT

Jupiter is an epizonal orogenic gold discovery roughly 30 km north of Valley. The four holes

reported herein from Jupiter were drilled at azimuths of roughly 330° and 300° (Table 3) to test

a potential secondary structural control on mineralization: steeply -dipping, east-west oriented

quartz-carbonate veins and breccias cutting at right angles to the primary controlling fold and

thrust geometry. The holes successfully intersect such mineralized structures, particularly in

the case of J-24-031, which returned a highlight interval of 6.81 g/t Au over 9.4 m, including

20.94 g/t Au over 2.1 m. These results expand the known footprint of high -grade gold

mineralization at Jupiter by over 50 m and provide useful geological information for advancing

exploration at Jupiter and on surrounding targets.

Hole J-24-031

Drillhole J-24-031 is collared in mudstone and intersects the siltstone unit marking the steep

flank of a fold interference pattern at a downhole depth of 246.5 m. An interval of 31.4 m

within the mudstone averages 0.68 g/t Au from 216.1 m downhole. This interval features

shallow south-dipping quartz-carbonate veins and a meter-thick, east-west oriented sub-

vertical quartz carbonate vein that contains visible gold (Figure 5).

Figure 4 – Map (left) and section (right) views of the Jupiter target , showing the locations and results of J -24-030 and J -24-031 in the context of

interpreted geology and surrounding drilling. To date, only a small portion of a broader 3 km soil anomaly at Jupiter has been tested by drilling, though

high grades have been encountered on a footprint of >1 km strike length. Additional targets like Galatea and Avalanche Creek 5 km and 12 km to the

south respectively along a prominent structu ral corridor, as we ll as the Mars target on a parallel structural corridor 4 km to the west, demonstrate

widespread potential for orogenic gold mineralization on the Einarson project.
