Vancouver, B.C., September 11, 2023: SNOWLINE GOLD CORP (TSX-V: SGD) (OTC:
SNWGF) (the “Company” or “Snowline”) is pleased to announce additional analytical results
from its ongoing drill program at the Valley target on its Rogue Project in Canada’s Yukon
Territory. All ten holes encountered mineralization, with the nine holes drilled inside the
intrusion returning continuous mineralization over downhole intervals ranging from 143.2 m
to 517.9 m in length. Holes V-23-045 and V-23-048 returned 517.9 m of 1.14 g/t Au and 265.2
m of 2.20 g/t Au respectively, from surface. This expands the width of the high -grade, near
surface core seen in previous holes, while V -23-045 also extends the depth of known
mineralization in the east. Other holes add substantial volumes of known mineralization to the
margins of the system as currently tested. Analytical results for an additional 19 holes (7,116
m) at Valley are pending, with drilling at Valley and other Rogue Project targets ongoing.

the known system, which remains open,” said Scott Berdahl, CEO & Director of Snowline.
“These holes primarily tested undefined margins of the well -mineralized corridor within t he
Valley intrusion. That they returned such strong grades—with holes running at multiples of the
0.64 g/t Au and 0.37 g/t Au average reserve grades seen at the nearest operating mines of this
type, across hundreds of metres—speaks to the unique nature of the Valley discovery amongst
reduced intrusion-related gold systems and among bulk tonnage gold systems in general. With
two rigs currently active on the target and one more on the nearby Gracie target , we look
forward to learning much more about these targets in the coming months.”
Figure 1 – Cross-section A, highlighting noteworthy continuity of strong, near-surface gold grades encountered at Valley. Holes V-23-
045 and V-23-048 bookend analytical results received to date on this section with long intervals of robust mineralization. Hole V-23-045
is the northeastern -most hole drilled into the well -mineralized, near-surface corridor at Valley, demonstrating a >400 m width to the
system that remains open. The hole also shows a continuity of mineralization to vertical depths of over 400 m below surface. Blank drill
traces show where results are still pending. Note that V-22-035 sits in the foreground of the section—V-23-045 and 048 are herein plotted
without interruption to highlight the recent results.
HOLE V-23-045
Hole V-23-045 is collared within the Valley intrusion as a 100 m step back along section from
V-23-037 (383.3 m @ 2.47 g/t Au from surface including 120.0 m @ 4.06 g/t, see Snowline
news release dated August 3, 2023). This step direction is perpendicular to the dominant trend
of mineralization, which strikes northwest -southeast. Thus the results add to the previously
known width of the system, which remains open. The hole is collared 67 m from the nearest
hole, V-22-029 (558.7 g/t Au @ 1.26 g/t Au, see Snowline news release dated February 24,
2023). The hole ends in patchy lower grade mineralization and fault gauge within a fine-grained,
porphyritic phase of the granodiorite (Figure 1).
The hole encountered a continuous zone of quartz vein mineralization in granodiorite over
517.9 m downhole from bedrock surface at 3.1 m, averaging 1.14 g/t Au along this length and
showing a high degree of continuity. Within this zone, a 125.5 m downhole interval beginning
at 196.5 m averages 1.75 g/t Au. Another interval of 16.5 m downhole beginning at 406.0 m
depth average s 5.07 g/t Au. Instances of trace visible gold were noted in quartz veins
throughout the length of the hole. Capping grades at 10.0 g/t Au reduces the average grade of
mineralization within the broader interval only 2.4% to 1.11 g/t Au.
Figure 2 – Plan view of the Rogue Project’s Valley target showing analytical results from previous and current drilling , along with approximate
traces of current holes. Current results, drilled primarily as step-outs from previous highlight holes, demonstrate the scale and the wide distribution
of unusually high grades for a reduced intrusion-related gold system at Valley, with most intervals beginning at or near surface. The system remains
open to the north and at depth, with more than 6,700 m of assays from Valley still pending and two drill rigs active on the target.
V-23-045 is the northeastern-most hole testing Valley’s well-mineralized corridor to date, and
it extends the envelope of known >1 g/t Au mineralization considerably in this direction, where
it still remains open. The hole also carries mineralization to depth, further expanding the known
vertical footprint and highlighting the vertical exploration potential within the Valley intrusion.
HOLE V-23-048
Hole V -23-048 is collared within the Valley intrusion as a 95 m step along section to the
southwest of V-23-039 (553.8 m @ 2.48 g/t Au, Snowline news release dated August 3, 2023).
The hole is collared 72 m south of the nearest hole, V-22-010 (318.8 m @ 2.55 g/t Au including
108.0 m @ 4.14 g/t Au from surface, see Snowline news release dated October 12, 2022).
Mineralization within V-23-048 is robust and consistent, averaging 2.20 g/t Au over 256.2 m,
including a higher-grade zone averaging 3.28 g/t Au over 100.2 m from bedrock surface at 8.8
m downhole. The top 30.2 m of the hole, measured downhole from bedrock surface, averages
5.03 g/t Au. As with many other holes at Valley, this grade profile sees the highest grades of
the system beginning at surface. Despite the high grades, only one assay exceeded 10 g/t Au
(10.1 g/t Au over 1.0 m from 23.0 m downhole). Grade capping at 10.0 g/t thus has virtually
no effect on results. As with other holes seen at Valley, this underscores the remarkable grade
continuity within the system.
The hole crosscuts abundant sheeted quartz veins within the intrusion, in places carrying trace
amounts of visible gold within the veins. It exits the intrusion into lightly mineralized hornfels
and a series of 1-2 m wide dikes at 255.9 m downhole.
Figure 3 – Cross-section A, showing quartz vein density per metre and instances of trace visible gold observed during logging. Together,
vein density and frequency of trace visible gold have shown to serve as a general indicator of grade potential at Valley. Not e that in a
sheeted quartz vein array like those present at Valley, the angle of veins to core can affect apparent densit y per metre. Density/visible
gold data for V-23-061 not yet available at time of writing, though a select run is shown in Figure 5. This figure complements Figure 1 of
this release.
Figure 4 – Cross-section B, showing V-23-047 in the context of surrounding holes and a simplified geological model . Top: Analytical
results received to date and still pending (thin black lines). Bottom: Vein densities alongside instances of trace visible gold observed during
logging. V-23-047 demonstrates that mineralization seen in V-22-032 continues to surface, with strongest grades near the top of the hole.
Table 2 – Summary of mineralization observed in current holes. The consistency of strong mineralization 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. The high results demonstrate uniform gold mineral ization that is not “smeared” across a given
interval by isolated high-grade samples. *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.

EXPLORATION UPDATES
Valley Target Drilling, Rogue Project
The 10,000+ m drill program at the Rogue Project’s Valley discovery is ongoing, with two drill
rigs active on site. To date, > 13,000 m has been drilled on the Valley target in 2023, with 29
holes completed and an additional 2 holes in progress. This represents more drilling at Valley
than the sum of all previous drilling on the target to date. Analytical results for 17 holes drilled
at Valley in 2023 are pending. The Company intends to continue drilling at Valley until the
end of the exploration season in early October.
Satellite Target Drilling, Rogue Project
Phase II drilling is ongoing at the Rogue Project’s Gracie target, with three holes completed in
2023 and a fourth hole, G-23-009, in progress. At present, >1,800 m has been drilled at Gracie
this season . Drilling at Gracie has encountered sedimentary rocks with varying degrees of
hornfels alteration, indicating proximity to an intrusion, and low-density sheeted quartz veins
bearing rare instances of trace visible gold. The goal of the Phase II drill program is to
intersection a causative intrusion for the widespread alteration and mineralization observed in
the Gracie target area.
At Reid, as previously described, LM-23-001 intersected a poly-phase intrusive system, with a
coarse-grained granodiorite phase and a fine -grained porphyritic phase, and moderate to low
vein densities. The hole was called at 623 m depth in coarse-grained granodiorite with low vein
densities. A total of 15 instances of trace visible gold were observed in the hole.
A short Phase I drill program was completed at the Cujo target, located roughly 30 km west of
Valley. CU -23-001 was drilled to 421 m in an exposure of a granodiorite intrusion with
anomalous gold geochemistry. The hole intersected low to moderate densities of sheeted quartz
veins. Nine instances of trace visible gold were observed during logging. A second hole, CU -
23-002 was initiated but was abandoned due to concerns about pad stability on subsurface ice,
and the rig was returned to Valley.
Results are pending for Rogue satellite target drilling.
Southwest Yukon Drilling
At the Tosh Property, the Company recently completed an expanded 5 hole, 1,719 m Phase I
program focused on the “Yarrow” gold-silver target, a zone of anomalous soils and rock grab
samples associated with mineralized breccias. This program is the first ever drill testing of the
Tosh Property.
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 202 3 field 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
orientation 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,
