Vancouver, B.C., December 22, 2022: SNOWLINE GOLD CORP. (CSE: SGD) (US
OTCQB: SNWGF) (the “ Company” or “ Snowline”) is pleased to announce additional
preliminary assay results from its 2022 drilling program at the Valley Zone, Rogue Project,
Yukon. Notably, hole V-22-032 intersected a zone of sheeted quartz vein mineralization within
the Valley intrusion averaging 1.72 g/t Au over 207.0 m within a broader mineralized zone
averaging 1.32 g/t Au over 338.0 m (Tables 1 and 2). The entire hole, including barren sections,
averaged 0.93 g/t Au across 532.7 m , ending in mineralized rock. The hole was collared 166
m from any other hole and drilled northeast to test the system between previously announced
V-22-005 (192.0 m @ 1.52 g/t Au) and V-22-010 (318.8 m @ 2.5 g/t Au).

“The latest results from Valley continue to demonstrate substantial scale and strong grades for
a reduced intrusion -related gold system,” said Scott Berdahl, CEO & Director of Snowline.
“Holes V-22-015 and 032 add considerably to the known tonnage of well-mineralized rock in
Valley’s central zone. The shape, the size , and the distribution of grades that we’re seeing at
Valley—with many of the highest grades encountered to date starting at surface —bode very
well for the potential economics of the discovery. We eagerly await remaining 2022 assay
results and their contributions to our understanding of this large mineralized system, with more
than 5,000 m still to come at Valley and all five holes (>2,000 m) still pending from our nearby
Gracie target.”
Table 1 – Preliminary highlight summary of Snowline’s latest assay results . *Interval widths reported ;
true widths of the system are not yet known. The geometry of the mineralized zone is not determined by
any individual vein nor structure and depends instead on the broader geometries of various vein arrays.
Figure 1 – 2021 and 2022 drilling at the Valley Zone, showing assays received to date (top) and vein densities alongside instances of visible
gold observed during logging (bottom). Visual results indicate the presence of a large central zone within the broader Valley intrusion bearing
higher vein densities. Initial analytical results for this zone consistently carry unusually high grades for a reduced intrusion-related gold system.
Figure 2 – Cross section A, showing results received (top) and vein densities alongside instances of visible gold observed
during logging (bottom). V-22-033 expands the known width of the mineralized zone locally to >300m . While broad zones of
continuous mineralization were not encountered at depth in this location, local intervals were . The deepest >1 g/t Au assay
ran 1.2 g/t Au over 1.5 m from 672.5 m downhole. Views look northwest.
Figure 3 – Cross section B, showing results received to date (top) and vein densities alongside instances of visible gold observed
during logging (bottom). V-22-015 was drilled to test the relatively high -grade mineralization encountered in V-22-014 and V-22-007
across a wider width and at depth. Views look northwest.
HOLE V-22-032
Hole V-22-032 was collared in hornfels sedimentary rock west of the Valley intrusion , and
drilled northeast, roughly perpendicular to the general southwest orientation of most drill holes
to date at Valley. On crossing into the intrusion at 91.6 m downhole, it averaged 1.32 g/t Au
over the subsequent 338.0 m, with a general increase in grades towards a gradational boundary
between intrusive phases encountered at 341.5 m downhole. The 100.5 m above this boundary
averaged 2.03 g/t Au, including a 20 m stretch near the boundary averaging 4.19 g/t Au.
The hole demonstrates further continuity of near-surface, gram to multiple gram per tonne gold
mineralization encountered in previous holes at Valley. The darker, porphyritic phase of t he
intrusion below the boundary may be a driver for higher grades in the lighter, medium-grained
granodiorite above (Figure 4).
As with previous holes at Valley, gold grades are carried across broad intervals, and they are
not heavily affected by local high-grade (>10 g/t Au) intersections (Table 2).

Table 2 – Summary of mineralization in current holes. Several zones of higher grades are present but capping these at 10 g/t Au shows that the intervals
are carried by robust mineralization along large zones within these higher -grade holes. *Interval widths reported; true widths of the system are not yet
known.
Figure 4 – Intrusive phase boundary in V -22-032, from 325.5 m to 351.7 m downhole, showing heavily veined, medium
grained granodiorite above roughly 341.5 m downhole, and a darker, fine-grained porphyritic phase of the intrusion below.
The polyphase nature of the intrusion is thought to be a factor in the dense veining and unusually high gold grades
encountered at Valley.
HOLE V-22-015
Hole V-22-015 was collared in the Valley intrusion on section with V-22-007 (410.0 m @ 1.89
g/t Au including 146.0 m @ 3.24 g/t Au) and V-22-014 (285.2 m @ 1.45 g/t Au including
128.2 m @ 2.48 g/t Au, see Snowline news release dated November 15, 2022 ), stepped back
roughly 182 m from V -22-007 to better test the width and depth of the system. V-22-015
encountered its highest grades within the upper two thirds of the hole. A broad zone of high
quartz vein density encountered lower in the hole (Figure 3) loosely correlates with zones of
the same darker, porphyritic phase of the intrusion seen in V -22-032. The abrupt decrease in
vein density at the intrusive phase boundary observed in that hole is thus not present in V-22-
015. Instead, a decrease in the regularity of bismuthinite and visible gold in the lower parts of
V-22-015 compared to veins seen roughly 200 m vertically above in V -22-007 appears to
correspond to a decrease in gold values.
ABOUT ROGUE
Rogue’s Valley Zone is a newly discovered, bulk tonnage style, reduced intrusion-related gold
system (RIRGS) , with geological similarities to multi-million-ounce deposits currently in
production like Kinross’s Fort Knox Mine in Alaska and Victoria Gold’s Eagle Mine in the
Yukon. Early drill results demonstrate unusually high gold grades for such a system present
near surface across intersections of hundreds of metres. Gold is associated with bismuthin ite
and telluride minerals hosted in sheeted quartz vein arrays along the margins of and within a
one-kilometer-scale, mid-Cretaceous aged Mayo -series intrusion. Valley is an early -stage
exploration project without a resource estimate, and while initial re sults are encouraging, the
presence or absence of an economically viable orebody cannot be determined until significant
additional work is completed.
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. The Rogue Project is thus considered by the Company to have district-
scale potential for additional reduced intrusion-related gold systems.
UPDATE ON PENDING ANALYTICAL RESULTS
The long processing times for analytical results are understood to be due to operational
constraints and high sample volumes at the Whitehorse sample preparation facility. To help
manage this backlog, ALS Laboratories has sent various Snowline sample batches to Langley,
BC, Sudbury, ON and Thunder Bay, ON. The Company expects this to decrease turnaround
time for analytical results on the remaining 17 holes drilled at Rogue in 2022. As evidenced by
the available results for late-season holes like V-22-032, this process also randomizes the
expected order of receipt of remaining analytical results.
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 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 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).
Samples with visible gold and other samples returning >2.0 g/t Au by fire assay, along with a
set of randomly selected samples, will undergo further processing, analysing the screen rejects
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.
Results reported herein are considered preliminary following receipt of a low but expected
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.) Reanalysis of 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 relatively consistent mineralization throughout mineralized zones, 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.
