• Hole V-22-010 returned 2.55 g/t Au over 318.8 m, including 4.14 g/t Au over 108.0
m from bedrock surface
• Hole demonstrates continuity of multi-gram mineralization seen in V-22-007 and
expands width of high-grade central corridor at Valley

• Monthly environmental baseline monitoring commenced at Valley.
Vancouver, B.C., October 12, 2022: SNOWLINE GOLD CORP. (CSE: SGD) (OTCQB:
SNWGF) (the “Company” or “ Snowline”) is pleased to announce additional preliminary1
assay results from its 2022 drilling program at the Valley Zone, Rogue Project, Yukon. Hole
V-22-010 intersected a broad zone of sheeted quartz vein mineralization within the Valley
intrusion averaging 2.55 g/t Au over 318.8 m from bedrock surface at 3.0 m downhole (Tables
1 and 2). The hole was collared more than 165 m from any previously announced hole, and it
expands to the southeast the known width of the zone of high vein densities within the Valley
intrusion (Figures 1 and 2).
“In the context of our initial 2022 drill assays from V-22-005 and V-22-007, these latest results
highlight a continuity of mineralization at Valley that we were hoping to see, with grades
exceeding our expectations,” said Scott Berdahl, CEO & Director of Snowline. “The results
change once again the way we think about the Valley gold system , and they continue to
challenge conventional perceptions of reduced-intrusion related gold systems in general. We
eagerly await the many forthcoming analytical results from our 2022 drill programs at Valley
1 These results are considered preliminary as 3 out of 43 of the Company’s QA/QC insertions of blanks and
standard reference materials into hole V-22-010 returned values of outside of acceptable limits. This is not an
unusual nor necessarily unexpected failure rate . In response, five samples on either side of failed insertions will
be reanalysed along with the insertions themselves . Given the scale and general consistency of the gold
mineralization across the hole s where insertions did pass QA/QC screening, the Company deems these
preliminary results to be strongly indicative of overall grade and thus material information. Final assay results
may be updated in a future release. For more information, see the QA/QC section of this release.

HOLE V-22-010
Hole V-22-010 was collared in the Valley intrusion, 180 m west of hole V-22-007 (282.9 m @
2.30 g/t Au including 146.0 m @ 3.24 g/t Au, see Snowline news release dated August 24,
2022). Similar to hole V -22-007, V-22-010 encountered a polyphase granodiorite to diorite
intrusion, with multiple generations of gold-bearing quartz veins present in the drill core. The
hole is notable not only for its high vein densities but also for the relative abundance of trace,
fine grained (sub millimeter scale) grains of visible gold, with over 120 instances of gold grains
observed along the length of the hole. Gold is commonly associated with bismuthinite and
telluride minerals in sheeted to near stockwork quartz veins. Overall sulphide content of the
system is very low.
Figure 1 – Cross section showing V-22-010 assay results in the context of vein densities in surrounding holes. Gold mineralization in the
hole continues for roughly 73 m downhole past the initial intrusive/hornfels contact at 321.8 m. Deeper holes V-22-029 and V-22-033 have
encountered trace instances of visible gold at depths of up to 562 m vertical below surface. Note that vein densities in V-22-033 and at the
bottom of V-22-010 are affected by sheeted quartz vein angles near core axis, thus underrepresenting true density. View looks northwest
along the strike of the system. The surface trace of the A to A’ cross section shown can be seen in Figure 2.
The hole exhibits a relatively high degree of consistency in gold grade. Of the top 108.0 m, 79
of 111 samples assayed higher than 2.0 g/t Au—representing 77.4 m (non-contiguous) or 71.7%
of the downhole interval. The lowest assay over this same stretch returned 0.59 g/t Au over 1.0
m from 107.0 m downhole. Of the entire 318.8 m interval reported from surface , 41.8% and
67.4% by (non-contiguous) distance assayed above 2.0 g/t Au and 1.0 g/t Au, respectively.
While high grades of up to 43.7 g/t (1.4 oz/ton) Au are present, they are not primary drivers of
the broader mineralized intervals. Applying a cap at 10 g/t Au reduces the top 108 m of the
hole by just 13.5% to 3.58 g/t Au, while the broader 318.8 m interval is affected less, dropping
7.8% to 2.35 g/t Au (Table 2).
The entire hole average s 2.18 g/t Au over its 401 m length from 3m to 404 m downhole ,
including barren zones. The last >0.1 g/t Au gold assay occurs as 0.85 g/t Au over 1.0 m from
394.0-395.0 m downhole, in an area where veins are oriented more closely to core axis.

ROGUE PROJECT INITIATIVES
In recognition of the potential significance of its drill discovery at Valley, the Company has
initiated environmental baseline monitoring in the vicinity of the pro ject. As of early October
2022, 11 water quality monitoring stations have been established for monthly sampling by an
independent third -party environmental firm, alongside 5 hydrometric stations to measure
stream flow levels within and around the Valley intrusion . These measurements will
complement weather and precipitation monitoring, alongside both planned and completed
wildlife, botanical and archaeological surveys , to provide baseline environmental data for
future progression of the project.
The Company has also engaged a metallurgical consultant for an initial evaluation of
mineralization at Rogue through gravity, leaching and communition tests. Early identification
of potential gold recovery processes will help to de -risk the project while guiding further
drilling and future economic studies to optimize exploration and potential development at
Valley and other targets on the property.
Three drill rigs will be wintered on site to allow for an early, rapid, and cost-effective start to
the next phase of exploration at Rogue.
ABOUT ROGUE
The geological setting and style of mineralization at Rogue’s Valley Zone indicate the presence
of a bulk tonnage gold target, with similarities to Kinross’s Fort Knox Mine in Alaska and
Victoria Gold’s Eagle Mine in the Yukon. Gold is associated with bismuthinite and telluride
minerals hosted in sheeted quartz vein arrays along the margins of a mid -Cretaceous aged
Mayo-series intrusion. The Rogue Project hosts multiple intrusions of similar age and affinity
to that at Valley along with widespread gold anomalism in stream sediment, soil and rock
samples. The project is thus considered by the Company to have district-scale potential for
reduced-intrusion related gold systems.
Valley is an early -stage exploration project without a resource estimate, and th e presence or
absence of an economically viable orebody cannot be determined until significant additional
work is completed. At writing, 91% of analytical results from the 2022 drill campaign (13,182
m of 14,495 m, comprising 11,030 m of 12,343 m at Valley and 2,152 m of 2,152 m at Gracie)
remain outstanding.
NOTE ON VEIN DENSITIES
Vein densities presented herein refer to the number of quartz veins apparent in a meter of core,
where a single quartz vein may range in thickness from millimetres to tens of centimetres. Such
densities are used by the Company, along side presence/absence o f visible gold and
bismuthinite, and average thickness of quartz veins, as a general indicator of gold potential to
guide exploration . They should not be interpreted as a direct analogue to assay results.
Additionally, the level of detail as currently logged varies between holes, with density values
for certain holes currently averaged across intervals of tens of metres, whereas densities for
other holes are split out at the metre scale. Angle of veins relative to core can also severely
affect observed density, as a hole drilled parallel to the orientation of sheeted quartz veins will
show a low vein density (e.g. V-22-033 in Figure 1) , whereas a hole drilled perpendicular to
veins in the same material will show a higher vein density. Finally, different vein arrays, and
even different regions within a laterally extensive vein array, may have variable gold content.
For interpretation and significance of any hole, the Company cautions that assay results are
required.
QA/QC
On receipt from the drill site, Valley’s NQ 2-sized drill core was systematically logged for
geological attributes, photographed and sampled at Snowline’s 2022 field camp. Sample
lengths as small as 0.5 m were used to isolate features of interest, 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) collected for analysis and one half stored as a record.
Standard reference materials, blanks and duplicate samples w ere 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 and by Snowline
personnel to ALS Laboratories’ preparatory facility in Whitehorse, Yukon, with analyses
completed in Vancouver.
ALS is accredited to ISO 17025:2005 UKAS ref 4028 for its laboratory analysis. Samples were
crushed by ALS to >70% 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 48-element analysis on 0.25 g sample
pulps (ALS code: ME-MS61L). All samples were analysed for gold content by fire assay with
an atomic absorption spectroscopy (AAS) finish on 30 g samples (ALS code: Au-AA23). Any
sample returning >10 g/t Au was reanalysed by fire assay with a gravimetric finish on a 30 g
sample (ALS code: Au-GRA21).
The entirety of hole V -22-010 will undergo screen reject analysis to determine whether the
screening process could introduce a sampling bias in current results by excluding coarse gold
from analysis, resulting in an under-reporting of true grades. Other biases are also possible.

As noted, results reported herein are considered preliminary following receipt of a low
percentage of abnormal assays from standard and blank samples inserted by the Company into
the Valley sample stream. (Standard samples are prepared by a third -party laboratory to have
known quantities of gold, and blank samples are known to contain very limited concentrations
of gold.) In total, 3 of 43 reference samples fell outside of acceptable limits. Reanalysis of
Table 3 – QA/QC failures from assay results received to date. 3 of 34 QA/QC samples returned values outside of 3 standard
deviations from an expected concentration (or, in the case of blanks, above detection limit). Most errors are small, and
overall they do not appear to reflect a systematic problem with the assays. Affected sample batches will be re-run to ensure
a high standard of data quality.
samples run along with these reference materials will provide greater certainty in the final assay
numbers. These results will be reported if a material difference is identified between the current
assays and the re-run sample batches. Based on the widespread and consistent mineralization
throughout V-22-010, however, the Company does not believe that the re -analysis of this
relatively small number of samples will have a significant impact on the preliminary
mineralized intervals reported herein.
