SUN SUMMIT PROVIDES UPDATE ON RECENT WILDFIRE ACTIVITY IN CENTRAL B.C.

Sun Summit Minerals Corp. has noted that an evacuation order has been issued south of the town of Houston in response to an uncontrolled wildfire in the region. Exploration activities have been temporarily suspended and all personnel have been demobilized from site until the situation improves.

Highlights

• Work has commenced for multistage exploration program: Exploration is focused on stepout drilling at Buck Main, targeting new zones of potential high-grade and bulk-tonnage mineralization in previously untested areas (see June 8, 2023, news release). In addition, surface exploration includes detailed mapping, prospecting and sampling in high-priority targets, including prospective new ground (see June 27, 2023, news release).
• Assay and geochemical analyses under way: Core samples from three completed drill holes, half of a fourth drill hole and 230 samples from surface exploration have been sent to the lab for assay and geochemical analyses, with results expected shortly.
• No significant delays anticipated: The company does not expect the wildfire to have a significant impact on the 2023 exploration program, which will resume as soon as it is safe and permissible to do so.

Sharyn Alexander, Sun Summit's president, stated: "We have temporarily suspended our exploration activities at the Buck project to ensure the safety of our employees and contractors. We are closely monitoring the wildfire development in the region and are in regular contact with local authorities. The safety of our employees, contractors and the local community is our top priority, and we extend our gratitude to the firefighters and emergency personnel working to control the wildfire. We will continue to monitor the situation and keep the market updated as the wildfire situation evolves."

To date, three diamond drill holes have been completed at Buck Main, with a portion of a fourth drill hole recovered, for a total of 1,219 core samples. The drill rig is currently on site and has not been demobilized. Extensive surface exploration has been conducted in the area of Mt. Morice and CR (recently acquired from Teck; see June 1, 2023, news release), with over 203 rock samples, 17 silt samples and 10 soil samples (for a total of 230 samples) collected by the field crew in high-priority areas. All drill core and surface samples have been shipped to the lab for assay and geochemical analysis.

The company is not aware of any damage or loss to infrastructure and will continue to monitor the situation and respond accordingly as the situation evolves.

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-sulphidation 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 centre 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.
