Sun Summit Announces Commencement of

Expansion Drilling at Its Buck Main Precious

Metals Project in Central B.C.

Vancouver, British Columbia--(Newsfile Corp. - June 8, 2023) - Sun Summit Minerals Corp. (TSXV:

SMN) (OTCQB: SMREF) is pleased to announce the commencement of drilling at its Buck Main project,

which marks the beginning of a multi-stage exploration program across its 52,000 hectare project area

in central British Columbia.

Highlights

Significant drilling at the Buck Main zone:

Approximately 3,500 metres over 15 priority

diamond drill holes in previously untested areas, both laterally and at depth.

Improved understanding of controls on mineralization:

Recent drill intercepts at Buck Main

were incorporated into an updated 3D model which has led to an improved understanding of the

geological and structural controls of

mineralization, which will assist in ongoing drill planning and

targeting.

Drilling designed to test untested areas:

Planned drill holes will test recently recognized fault

structures and veins that are often associated with high-grade mineralization elsewhere within the

Buck Main zone.

"We have acquired and expanded a significant land package in an emerging polymetallic belt in central

B.C., and our recent oversubscribed financing allows us to hit the ground running," stated Sharyn

Alexander, Sun Summit's President. "Updating our geological modelling and structural analysis at Buck

Main has led to a refinement of the known controls on mineralization. This new understanding has helped

in the planning of step-out drill holes focused on targeting new zones of potential high-grade and bulk-

tonnage mineralization. In addition, our multi-stage exploration program will provide ongoing newsflow

throughout the summer as we continue to explore emerging targets on our expanding project area."

Buck Main Drilling

Drilling at Buck Main is expected to commence mid-June

and will initially consist of approximately

3,500 metres over 15 drill holes. The drill program was designed to test the potential high-grade core of

the epithermal-related gold-silver-zinc system with a particular focus on previously unrecognized fault

structures and high-density vein zones.

Drilling will incorporate new insights from the recently updated 3D model which allowed for the

refinement of host lithologies and structures that are thought to control emplacement of hydrothermal

breccias and vein sets in the overall structural corridor setting. In particular, modeling has allowed for the

refinement of sub-units of key host andesitic volcaniclastic and dacitic pyroclastic rocks with a particular

focus on structural controls that appear to define host plunge orientations thus far unrecognized at Buck

Main. Modeling also revealed quartz feldspar dykes (QFPs) likely were emplaced in a later

mineralization event. Other targets include hydrothermal breccias thought to occur at the modeled

intersection of growth and transform faults, and presumed heavily disseminated mineralization domains

where growth faults may project into coarse, dacitic pyroclastic sub-units. Additional drilling will be

considered based on a successful outcome.

Since 2020, the Company has completed 84 drill holes at Buck Main for over 30,000 metres.

Results

demonstrate significant mineral deposit potential with district wide size and scale

opportunities. Recent

drilling focused on expanding the footprint of near-surface bulk tonnage-style mineralization and

demonstrated strong expansion potential to west, north and south. The known mineralized footprint

measures over one kilometre in strike length with mineralization open in all directions.

Broad zones of bulk tonnage-style disseminated mineralization

are indicated by:

0.71 g/t Au, 5.6 g/t Ag, 0.62% Zn over 187 m (BK21-033)

1.07 g/t Au, 5.5 g/t Ag, 0.65% Zn over 109 m (BK21-017)

Significant high-grade mineralization

is indicated by:

49.6 g/t Au, 10.8 g/t Ag, 0.06% Zn over 1.5 m (BK20-012)

246 g/t Au, 66.7 g/t Ag, 0.02% Zn over 0.5 m (BK21-020)

38.0 g/t Au, 137 g/t Ag, 5.9% Zn over 1.1 m (BK22-083)

Note drill intercepts are measured downhole and are not true widths.

National Instrument 43-101 Disclosure

This news release has been approved by Sun Summit's Vice President Exploration, Ken MacDonald, P.

Geo., a "Qualified Person" as defined in National Instrument 43-101,

Standards of Disclosure for

Mineral Projects

of the Canadian Securities Administrators. He has also verified the data disclosed,

including sampling, analytical and test data, underlying the technical information in this news release.

Community Engagement

Sun Summit is engaging with First Nations on whose territory the Buck Project is located and is

discussing their interests and identifying contract and work opportunities, as well as opportunities to

support community initiatives. The Company looks forward to continuing to work with local and regional

First Nations as the project continues.

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.
