SNOWLINE GOLD BUILDS ON NEAR SURFACE MINERALIZATION WITH 2.1 GRAMS

PER TONNE GOLD OVER 433.5 M AT ITS VALLEY DEPOSIT, YUKON AND INITIATES

CLEAN-UP PROJECT ON HISTORICAL MINING SITE

• Hole V-24-081 returned 2.10 g/t Au over 433.5 m, including 3.42 g/t Au over 96.5

m and 3.20 g/t Au over 50.5 m, bolstering scale of high-grade, near-surface gold

mineralization at Snowline’s Valley deposit, Rogue Project

• Hole V-24-084 returned 1.31 g/t Au over 273.2 m, including 2.18 g/t Au over 120.7

m from surface, surpassing mineral resource estimate block model expectations near

the southeastern part of the Valley deposit

• Phase I reclamation work completed by Snowline at historical “Plata” staging area,

southwest of the Rogue Project, which supported 1980s mining activity in the area

from the Plata winter trail

• Assays remain pending for >24,600 m in 45 holes across 6 targets at Snowline’s

Rogue and Einarson projects.

Vancouver, B.C., October 10, 2024: SNOWLINE GOLD CORP ( TSX-V: SGD) (OTC:

SNWGF) (the “Company” or “Snowline”) is pleased to announce additional analytical results

from its 2024 Valley deposit drilling campaign on the Rogue Project in Canada’s Yukon

Territory alongside updates on its regional activities. Holes V-24-081 and V-24-084 returned

strong, consistent gold grades from near -surface along the southwestern edge of the Valley

deposit, outperforming the model used for the Company’s initial mineral resource estimate

(MRE) earlier this year. In addition, Snowline has completed the first phase of a reclamation

program at the Plata mining camp near the Rogue Project, organizing and inventorying debris

and abandoned equipment from historical mining activities in the region for future

demobilisation. The Company awaits analytical results from the majority of its 2024

exploration campaign, including >24,600 m of drilling in 44 holes across 5 different targets.

“It is a testament to the consistency of mineralization at Valley that results like today’s have

become almost commonplace,” said Scott Berdahl, CEO & Director of Snowline. “Nonetheless,

they further demonstrate the strength of the system near surface, and key holes V -24-081 and

V-24-084 outperform our model along the southwest margin of the deposit.

details. *Interval widths reported ; true widths of the system at Valley are not yet

known.

“We are also pleased to report completion of the first stage of a meaningful side project – the

cleanup of the historical Plata s taging area, which supported small-scale mining efforts in the

region in the early 1980s. We would like to thank Honey Badger Silver Inc. and Archer, Cathro

& Associates for their assistance in these efforts. This work builds on Snowline’s commitment

to contribute to a lasting positive legacy for mining in the Yukon.”

VALLEY DRILLING, ROGUE PROJECT

Roughly 25,000 m have been drilled at Valley in 55 holes in 2024 (Figure 1) – nearly double

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

instances of visible gold and widespread sheeted quartz vein arrays have been observed both

within and beyond the confines of the MRE. The Company awaits full assay results from the

2024 drill campaign to assess the significance of these observations and their impact on the

deposit.

Figure 1 – Plan map of drill results and progress on the Rogue Project’s Valley deposit, highlighting current results in drill holes V-24-

081 through V-24-087. Past analytical results are faded, while instances of visible gold in holes awaiting assay are marked by yellow

spheres. Drill holes with assays pending are labelled in blue.

Hole V-24-081

Hole V-24-081 is collared within the Valley intrusion, roughly 42 m east of V-23-053 and 73

m northwest of V-23-051. The hole is drilled to the northeast, as opposed to the more common

southwest orientation at Valley, to more effectively test local near -surface mineralization and

to get information from gaps in drilling at depth.

The hole runs through coarse -grained granodiorite for most of its length, with a zone of fine-

grained porphyritic granodiorite from roughly 336 m to 446 m downhole containing xenoliths

of granodiorite, hornfels and chert. A total of 121 instances of visible gold were noted along

the length of the hole during logging.

The results of this hole are expected to help upgrade and de -risk relevant areas of the initial

mineral resource estimate for Valley. Notably, the hole redefines the local, near -surface

southwest boundary of the intrusion, as the previous geological model (used to inform the

initial MRE at Valley) suggested V -24-081 would have collared into hornfels. 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.

0.72 pit shell. The block model has not been updated to reflect the current results, nor any results to date from 2024, and blocks shown outside

of the current pit shell constraint are not included in the initial MRE for Valley. Instances of visible gold in holes still awaiting assay results are

marked by yellow spheres. The released holes are projected onto the same plane from a total width of roughly 50 m—relative positions can

be seen in the plan map in Figure 1.

the 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. *Interval widths reported; true widths of the system are not yet known, with different vein generations, orientations,

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

PLATA SITE CLEANUP

In September, Snowline completed the first phase of a site cleanup program at the historical

Plata staging area. Work consisted of documenting, inventorying , stockpiling and limited

removal of abandoned equipment and materials from historical exploration and mining activity

related to mining in the area primarily in the 1980s, which included small scale underground

silver mining. Stockpiled materials have been consolidated and prepared for future removal

from site.

The Plata staging area is located along an airstrip at the north end of the Plata winter trail

(Figure 4) roughly 8 km west of Snowline’s Rogue Pro ject. The site is strategically located ,

and Snowline has used the staging area in the past to support its own operations.

QA/QC

On receipt from the drill site NQ 2-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 orientat ion 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 b y 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 <0.1 g/t Au and may include any highlight

subsections thereof.

ABOUT ROGUE

Snowline Gold’s 100%-owned, flagship Rogue Project, in Canada’s Yukon Territory, covers

a 60 x 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 Moz

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, P. Geo., Daniel J. Redmond, P. Geo. , and Steven C.

Haggarty, P. Eng., with an effective date of May 15, 2024.

Exploration of the open Valley system is ongoing. Valley is a reduced intrusion -related gold

system (RIRGS), geologically similar to multi-million-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 -kilometer-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.

Figure 4 – Project location map for Snowline Gold’s eastern Selwyn Basin properties: Rogue, Einarson, Ursa, Cynthia

and Olympus. The Valley target is one of several prospective reduced intrusion -related gold targets on the broader

30 x 60 km Rogue Project . The Plata sta ging area is located at the northern end of the Plata winter trai l, which

connects to the government maintained North Canol Road.
