Sun Summit Discovers Multiple Near-Surface
Zones of Bulk-Tonnage Style Gold-Silver-Zinc
Mineralization and Significantly Enhances the
Exploration Potential at the Buck Property,
Central B.C.
Vancouver, British Columbia--(Newsfile Corp. - February 22, 2022) - Sun Summit Minerals Corp.
(TSXV: SMN) (OTCQB: SMREF) is pleased to report drill results and the discovery of additional near-
surface zones of bulk-tonnage style gold-silver-zinc mineralization from its fall 2021 exploration program
on its Buck Property, central B.C.
Highlights
Discovery of new zone of near-surface, breccia-hosted, gold-silver-zinc mineralization
along strike to the northwest
(e.g.,
1.85 g/t gold equivalent (AuEq)
2
over 25 metres
including
8.78 g/t AuEq over 3.9 metres
; BK21-060).
Discovery of additional bulk-tonnage style gold-silver-zinc mineralization in step-out
holes to the west of previous drilling
(e.g.,
0.61 g/t AuEq over 155.8 metres
including
1.37
g/t AuEq over 16.3 metres
; BK21-059).
Confirmation of continuity of gold-silver-zinc mineralization in the previously untested
area between the historic Horseshoe and Trench zones
(e.g.,
1.11 g/t AuEq over 51.0
metres
including
1.81 g/t AuEq over 13.6 metres
; BK21-048).
These new and open areas will be tested in the current drill program; crews have
mobilized to site and the drill is turning
.
Recalculation of gold equivalent (AuEq) including zinc has yielded significant increases
in values which has the potential to be a significant economic contributor to the overall
metal value of the property
(see news release
February 8, 2022
). Examples of significant

1 Intervals are downhole core lengths. True widths are unknown.
2 New AuEq (AgZn) calculations assume metal prices of $1700/oz Au, $22/oz Ag and $1.60/lbs Zn using the equation:
AuEq(g/t) = ((Au(g/t)*$Au/oz*0.032151)+(Ag(g/t)*$Ag/oz*0.032151)+(Zn%*$Zn/lbs*22.0462))/($Au/oz*0.032151).
3 Previous AuEq (Ag) calculations were based on a 65:1 or 75:1 silver to gold (Ag:Au) ratio.
Sharyn Alexander, Sun Summit's President, stated: "The results from our remaining holes from the
recent drill program are highly encouraging and are in line with what we expected to see from the fall
2021 program. This phase of drilling was designed on a grid pattern with consistent orientations to
model different mineralized zones, and particularly, to tie together structural and lithological trends.
Modelling is ongoing but the drilling succeeded in building a more coherent picture of the Buck Main
mineralized system. All holes intersected mineralized zones and reinforces our belief that the system is
much larger and has more continuity and consistency than was previously recognized. Two new areas of
mineralization have been discovered in previously untested areas to the west and north-west, which
enhances the exploration upside at Buck Main. We are very optimistic about the potential for higher
grade intercepts in the current drill phase which will target higher grade zones and continue to expand
the footprint of this complex hydrothermal system."

Sun Summit completed a 32 hole diamond drill program for 10,327 metres in late 2021, with initial
results of the first eight holes reported on
January 5, 2022
. All holes were drilled along northeast-
southwest oriented sections with holes drilled with orientations to the northeast at varying inclination. The
program of grid-based drilling allowed the systematic generation of cross-sections across the Buck
Main target, and was successful at building the geological and structural model to further define the
potential of the system for gold, silver and zinc mineralization. Modelling is ongoing and is being refined
as we receive new data from the current drill program.
Results from the reported 24 holes across the western side of Buck Main confirm the presence of near-
surface, disseminated gold-silver-zinc mineralization and local vein-hosted high-grade gold and silver
mineralization. The focus going forward will be to continue to investigate the limits of the hydrothermal
system while testing new structural targets and areas peripheral to Buck Main, with the goal of defining
higher-grade zones.
A series of holes tested the northwest-trending structural contact between sedimentary and volcaniclastic
rocks with dacitic lapilli tuffs and breccias (Figure 2). The holes were designed to expand the footprint of
breccia-hosted gold-silver-zinc mineralization associated with pyrite + sphalerite cemented, clast-rich
hydrothermal breccias (e.g., 46 metres of 1.59 g/t AuEq* in BK20-006, 40 metres of 1.84 g/t AuEq* in
BK20-012, and 45 metres of 2.36 g/t AuEq* in BK21-017; Table 2).
Hole BK21-060 was collared approximately 180 metres northwest of BK21-017 and intersected 1.85 g/t
AuEq* (0.92 g/t Au, 12.33 g/t Ag, 1.2% Zn) over 25 metres including 8.78 g/t AuEq* (4.81 g/t Au, 26.03
g/t Ag, 5.6% Zn) over 3.9 metres associated with sphalerite-cemented hydrothermal breccias.
Hole BK21-060 was drilled in an area with limited outcrop and no historic drilling and was designed
based on visual observations and updated modelling from preceding holes (e.g., BK21-048 and 058).
This zone of strong gold-silver-zinc mineralization is open in all directions and represents a priority target
for further testing in the current drill program.
Holes BK21-059 and 065 tested the westernmost limit of the system and were drilled from the same
section (Figure 2). The holes were set up 150 metres apart and collared in andesitic volcanic rocks and
sedimentary rocks which transitioned to strongly altered and mineralized dacitic lapilli tuffs. Both holes
intersected broad zones of gold-silver-zinc mineralization hosted in lapilli tuffs (e.g., 0.61 g/t AuEq* over
155.8 metres, including 1.37 g/t AuEq* over 16.3 metres and 1.05 g/t AuEq* over 17.0 metres, from
surface in BK21-059; and 0.55 g/t AuEq* over 146.9 metres, including 1.10 g/t AuEq* over 13.7 metres
and 0.84 g/t AuEq* over 32.9 metres in BK21-065). These volcaniclastic breccias are lithologically
similar to dacitic lapilli tuffs found over 400 metres to the east in the historic Horseshoe zone, host to
long intervals of gold-silver-zinc mineralization (e.g., 409 metres of 0.87 g/t AuEq* in BK21-033). The
presence of these rocks in the westernmost holes represents a positive development in the exploration
potential of the Buck Main target and opens the area to the west for expansion.
* Intervals are downhole core lengths. True widths are unknown. Intervals recalculated using zinc concentration and the previously stated formula.
Gold and silver values were previously reported on
January 5, 2021
and
May 11, 2021
.
Twenty four holes are reported with selected highlights shown in Table 1.

1. Intervals are downhole core lengths. True widths are unknown. Calculations are uncut and length-weighted using a 0.10 g/t gold cutoff.
2. AuEq assumes metal prices of $1700/oz Au, $22/oz Ag and $1.60/lbs Zn using the equation: AuEq(g/t) = ((Au(g/t)*$Au/oz*0.032151) +
(Ag(g/t)*$Ag/oz*0.032151) + (Zn%*$Zn/lbs*22.0462)) / ($Au/oz*0.032151)
.
Zinc Mineralization
Widespread sphalerite (zinc-sulfide) mineralization was intersected in all drill holes across the property.
Preliminary metallurgical test work suggests zinc is highly recoverable using conventional methods (see
news release
January 8, 2022
) and may contribute favourably to future economic studies. As a result,
gold equivalent (AuEq) values were recalculated for selected holes including zinc, which significantly
increased previously reported grades (Table 2).

3. Previous AuEq (Ag) calculations were based on a 65:1 or 75:1 silver to gold (Ag:Au) ratio.
4. AuEq recalculations were previously reported (
January 8, 2022
).

Quality Assurance and Quality Control
All sample assay results have been monitored through the Company's quality assurance / quality control
(QA/QC) program. Drill core was sawn in half at Sun Summit's core logging and processing facility in
Houston, B.C. Half of the core was sampled and shipped in sealed and secure bags to the ALS Global
preparation facilities in Kamloops, Langley or North Vancouver, B.C. Samples were prepared using
standard preparation procedures. Following sample preparation, the pulps were sent to the ALS Global
analytical laboratory in North Vancouver, B.C. for analysis.
Core samples were analyzed for 48 elements by ICP-MS on a 0.25 gram sample using a four acid
digestion (method ME-MS61L). Gold was analyzed by fire assay on a 30 gram sample with an AAS
finish (method Au-AA23). Samples with >10 parts per million (ppm) gold were re-analyzed by fire assay
using a gravimetric finish on a 30 gram sample. Samples with >100 ppm silver were re-analyzed using a
four acid digestion and ICP-AES finish. Samples with >10,000 ppm zinc were re-analysed using a four
acid digestion and ICP-AES finish. ALS Global is registered to ISO / IEC 17025:2017 accreditations for
laboratory procedures.
