Sun Summit to Acquire Drill-Ready Porphyry

Cu-Mo Property; Consolidates Significant

Land Position in Emerging Mineral Belt in

Central B.C.

Vancouver, British Columbia--(Newsfile Corp. - June 1, 2023) - Sun Summit Minerals Corp. (TSXV:

SMN) (OTCQB: SMREF) is pleased to announce it has agreed to the acquisition of the 8,964 hectare

CR property from Teck Resources Limited, located adjacent to Sun Summit's 43,000 hectare Buck

property in central B.C.

Highlights of the acquisition include:

Drill-ready porphyry copper-molybdenum property:

The CR property has multiple, near-

surface copper zones with historic drill holes that bottomed in 0.1-0.5% Cu; highlights include: 68

metres at 0.50% Cu, 0.015% Mo; and 168 metres at 0.37% Cu, 0.017% Mo*.

Potential for discovery and expansion:

The CR property is underexplored with numerous

untested porphyry and epithermal targets.

Large property with existing exploration permit:

Roughly 8,900 hectare property with an

existing exploration drill permit.

Road accessible and excellent infrastructure

: The CR property straddles a well-maintained

forestry road that also serves as the haul road to the Huckleberry Mine. The Huckleberry Mine is

less then 100 kilometres to the south with an industrial powerline running alongside the forestry

road.

Expansion of Land Holdings:

Expansion of a significant land position in the emerging central

British Columbia porphyry-epithermal belt.

Favourable acquisition terms

: The terms include acquisition of 100% ownership interest for Sun

Summit shares and a net smelter return royalty (NSR) royalty, and no cash consideration or

exploration commitments.

Sharyn Alexander, Sun Summit's President commented, "The combination of the CR property with the

Buck property greatly increases our land holding in the area. This drill-ready project is located within a

highly-prospective region of central British Columbia known for gold and copper systems. The property

is road and powerline accessible and comes with favourable acquisition terms that provides tremendous

value for shareholders. The area has excellent exploration upside and demonstrated potential for

porphyry-related mineralization in two drill-tested zones, plus mapped occurrences of skarn Au-Cu and

epithermal Au-Ag mineralization elsewhere on the property that have seen only limited examination. We

are pleased to add a compelling copper component to our ongoing exploration efforts and see great

potential to expand the mineralized areas at both CR and Buck. We are excited to begin work on our

growing land package in this emerging and significant mineral district in central B.C."

The CR property is comprised of 19 contiguous mineral claims totalling 8,964 hectares and is

contiguous to the Buck property on Buck's western border (Figure 1). Combined, these two properties

total 55 mineral claims covering 52,000 hectares (520 square kilometres), which expands the

Company's land position by more then 20%.

The most significant drill intercepts are reported from the CR property's South Zone, which includes:

168 metres at 0.37% Cu, 0.017% Mo

(8-176 metres, DDH CR-07-14*)

68 metres at 0.50% Cu, 0.015% Mo

(14-83 metres, DDH CR05-03*)

105 metres at 0.35% Cu, 0.024% Mo

(bottom 195-300 metres, ending in 0.5% Cu, DDH CR07-

15*)

Terms of Acquisition

Sun Summit will acquire a 100% interest in the CR property through the issuance of 2,272,727 Sun

Summit common shares valued at $250,000 based on the 20-day volume weighted average price of

Sun Summit shares. Teck will retain a 1.0% NSR royalty on the property, of which one-half (0.5%) may

be re-purchased for $2,000,000 at any time, resulting in Teck retaining a 0.5% NSR royalty. There is a

pre-existing 0.5% NSR royalty to the original landowner which can be re-purchased for $10,000,000. The

shares will be subject to a four month hold period in accordance with Canadian Securities laws.

About the CR Property

The CR property is located 15 kilometres southwest of Houston in west-central British Columbia and can

be accessed by the all-season Morice River Forest Service Road (FSR) which accesses commercial

timber licenses and leads south to Imperial Metal's Huckleberry Mine. The Huckleberry Mine powerline

transects the property from north to south. Secondary forestry roads provide good access to various

targets on the property. A major highway, high-voltage power, gas pipeline, deep seaport and airport are

in close proximity.

The CR property is underlain mainly by a sequence of Jurassic andesitic to rhyolitic tuffs, flows and

volcaniclastic rocks of the Telkwa Formation of the Hazelton Group cut by intrusive dykes and stocks of

variable porphyritic textures. Granodiorite and quartz-feldspar porphyry intrusions are associated with

Cu-Mo porphyry-style mineralization at two zones: North Zone and South Zone. The South Zone is better

exposed at surface and has been partially delineated by historical diamond drilling, whereas the North

Zone is variably till-covered and was drill tested with two holes for the first time in 2019. Less well-

understood vein, breccia and skarn showings have been delineated across the property.

Past exploration work has focused mainly on the South Zone and includes diamond drilling by Manson

Creek Resources Ltd. which completed a total of 3,567 metres of diamond drilling in 2005 and 2007.

Copper mineralization in the South Zone is understood to be hosted in an east-west porphyry system

that measures roughly 700 metres wide and is possibly tilted to the east. A large IP chargeability-high

anomaly associated with mineralization at the South Zone extends to the north, south and east, as well

as to depth. Mineralization in the granodiorite is reported as disseminated chalcopyrite with rare bornite,

as well as chalcopyrite-pyrite±molybdenite veins and hydrothermal breccia cement. Higher copper

grades are reported to be associated with intense K-feldspar±quartz alteration. The most significant

mineralization reported to date occurs in the hydrothermal breccias which host episodic mineralization

including an early phase of chalcopyrite-magnetite followed by a later quartz-sericite-pyrite event.

Manson Creek's drill pattern tested an east-west corridor, leaving possible extensions to the north, east

and south untested. Many of the historical drill holes were relatively short (i.e., less than 300 metres from

surface) and some terminated in mineralization.

Teck completed a 2018 field program consisting of an airborne magnetic-radiometric survey, stream

sediment sample survey, and a geological mapping program. In 2019, Teck completed the first two drill

tests of the North Zone, expanded ground IP coverage over the northeast quadrant of the property, and

collected soil samples over the North Zone IP anomaly.

The North Zone is poorly exposed at surface but limited mapping has shown the zone is characterized by

hydrothermal breccia, sodic-calcic altered granodiorite, and quartz-sericite altered quartz feldspar

porphyry over several hectares. Two diamond drill holes totalling 876.5 metres tested the southern

segment of a large IP chargeability high anomaly at the North Zone and intersected widespread pyrite

mineralization with weak chalcopyrite hosted in both andesitic strata and granodiorite intrusions. The

style and intensity of alteration and sulphide mineralization suggest the North Zone may represent the

distal portion of a copper porphyry system.

There has been no work on the property since 2019 and many targets remain to be tested. Future work

will focus on expansion of the east-west corridor at the South Zone by drill testing at depth and along

strike where there is significant potential to expand the mineralized footprint into untested areas of the

large chargeability anomaly. The large North Zone IP chargeability high anomaly remains largely

untested and further assessment is required to plan drilling on the middle and north segments. A gap of

approximately 850 metres separates the chargeability anomalies of the North and South zones and

requires additional survey to examine any linkages between the two zones.

About the Buck Project

The Buck Project is situated in a historic mining district near Houston, B.C., with excellent nearby

infrastructure that allows for year-round, road-accessible exploration.

The project is host to the Buck Main intermediate-sulfidation epithermal-related gold-silver-zinc system.

Most of the mineralization drilled to date at Buck Main consists of long, continuous zones of

disseminated and breccia-hosted, bulk tonnage-style gold-silver-zinc. Vein-hosted, high-grade

mineralization has also been intersected near the center of Buck Main.

Exploration at the Buck Project is focused on investigating the lateral and vertical extent of gold-silver-

zinc mineralization at the Buck Main system, and to define additional drill targets across the entire land

package through systematic exploration programs.
