Vancouver, British Columbia--(Newsfile Corp. - December 19, 2024) - Sun Summit Minerals Corp. (TSXV: SMN) (OTCQB: SMREF) is pleased to provide a corporate update and review of key activities and achievements from 2024.

Top Highlights From 2024:

• Successful execution of the JD Project option agreement: In January 2024, Sun Summit entered into a definitive option agreement to acquire 100% of the JD Project in the Toodoggone gold-copper district in north-central B.C. (see January 9th, 2024, news release). The JD Project contains numerous under-explored epithermal-related gold-silver targets as well as porphyry-related copper-gold targets in an emerging mining district.

• Completion of an extensive exploration program at JD: An extensive exploration program was completed in 2024 at the JD Project, which included over 2,500 metres of diamond drilling across 12 holes, aimed at the expansion of known mineralized zones and testing new high-priority targets. Additional activities included the collection of soil and rock samples, a 20-line kilometre Induced Polarization (IP) survey, and a property-wide LiDAR survey. These efforts identified new drill targets and expanded our understanding of the geologic model at the JD Project (see September 5th, 2024, news release).

• High-grade gold identified at the Creek Zone: The inaugural drill program at the Creek Zone delivered significant results, building on historical data and uncovering new zones of mineralization, confirming high-grade and bulk-tonnage potential (see September 19th, October 2nd, and October 16th, 2024, news releases). Notable highlights* include:

  • 122.5 metres of 2.1 g/t Au, including 20.0 metres of 10.0 g/t Au (CZ-24-004).

  • 57.95 metres of 2.7 g/t Au, including 19.5 metres of 7.3 g/t Au (CZ-24-005).

• Aggressive exploration being planned for 2025: Exploration will focus on confirmation, infill, and step-out drilling at Finn and Creek Zones designed to investigate the extent and continuity of high-grade and bulk-tonnage gold mineralization. Additional high-priority targets will be explored through geological, geochemical, and geophysical surveys (see November 26th, 2024, news release).

• Completion of option agreement of Buck Project: In October 2024, Sun Summit completed the earn-in agreement to own 100% of the Buck Project in central B.C. The Buck Main zone demonstrates strong expansion potential for both disseminated and high-grade gold and silver mineralization, and an initial Mineral Resource Estimate is currently being completed.

"This year has been a transformative period for Sun Summit," stated Sharyn Alexander, Sun Summit's President. "Our results at the Creek Zone have not only confirmed historic results but also exceeded our expectations, validating our strategic decision to intensify our exploration efforts. Our 2025 exploration plans aim to build on this momentum with a clear focus on resource definition and new discoveries. With a robust technical foundation and a pipeline of high-priority targets, we are excited to continue unlocking the potential of this world-class district, ensuring that we continue to create value for our shareholders and strengthen our position. We thank our shareholders for their loyalty and support and look forward to providing additional updates as our work progresses."

2025 Exploration Plans

The Company plans to fully evaluate the significant high-grade and bulk-tonnage gold potential at the Creek and Finn Zones through targeted and infill drilling. Project-wide exploration activities are also planned to advance multiple new and existing high-priority targets.

The Finn Zone will be a major focus of the 2025 exploration program, where drilling will be designed to confirm the presence of high-grade gold-silver mineralization intersected in historical drilling. Infill and step-out holes will be designed to investigate the continuity and extent of structurally controlled base-metal-rich epithermal-related mineralization. Infill drilling near the center of the high-grade core will be conducted to verify historical grades, confirm structural controls, and explore at depth to assess the geometry and grade of the footwall zone. Step-out drilling down-dip and along strike would also evaluate mineralization continuity and identify potential high-grade zones.

Significant historical intercepts* at the Finn Zone include:

• 35.7 m of 7.3 g/t Au including 1.0 m of 215.4 g/t Au (JD95-047)

• 22.0 m of 12.5 g/t Au including 0.8 m of 171.5 g/t Au (JD95-064)

• 25.9 m of 6.4 g/t Au including 6.1 m of 12.8 g/t Au (JD94-015)

• 27.8 m of 6.6 g/t Au including 11.0 m of 15.1 g/t Au (JD95-097)

Follow-up drilling at the Creek Zone will focus on step-out and infill drilling to explore the extent and continuity of high-grade and bulk-tonnage gold mineralization, aiming to expand the known mineral footprint. Recent drilling by Sun Summit identified the presence of previously undocumented bulk-tonnage mineralization and confirmed the presence of high-grade mineralization. The Creek Zone remains open in multiple directions and at depth, providing numerous opportunities for expansion.

Historical and recent highlight intercepts* at the Creek Zone include:

• 122.5 m of 2.1 g/t Au including 1.5 of 121.0 g/t Au (CZ-24-004)

• 54.95 m of 2.7 g/t Au including 19.5 m of 7.3 g/t Au (CZ-24-005)

• 22.0 m of 11.7 g/t Au including 4.0 m of 61.2 g/t Au (CZ97-008)

• 21.5 m of 3.1 g/t Au including 3.0 m of 18.7 g/t Au (CZ98-012)

Sun Summit will also investigate the potential of several newly identified epithermal gold-silver and porphyry copper-gold targets, which could include JD West, Wolf, Schmidt, Creek North, Belle, and Fericrete zones. All JD-wide targets will be ranked and prioritised prior to the 2025 exploration program.

The Company looks forward to continuing to work with local and regional First Nations with ongoing exploration.

About the JD Project

The JD Project is located in the Toodoggone mining district in north-central British Columbia, a highly prospective deposit-rich mineral trend. The project covers an area of over 15,000 hectares and is in close proximity to active exploration and development projects, such as Thesis Gold's Lawyers and Ranch projects, TDG Gold's Baker-Shasta projects, Centerra's Gold's Kemess East and Underground projects, as well as the past-producing Kemess open pit copper-gold mine.

The project is 450 kilometres northwest of the city of Prince George, and 25 kilometres north of the Sturdee airstrip. It is proximal to existing infrastructure in place to support the past-producing Kemess mine, including roads and a hydroelectric power line.

The JD Project is in a favourable geological environment characterized by both high-grade epithermal gold and silver mineralization, as well as porphyry-related copper and gold mineralization. Some historical exploration, including drilling, geochemistry and geophysics, has been carried out on the property, however the project area is largely underexplored.

About the Buck Project

The 100% owned 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 60 kilometres southeast of Smithers and is located west of the past producing Equity Silver Mine (Newmont) and north of the Huckleberry copper mine (Imperial Metals).

The project is host to the Buck Main intermediate-sulfidation, epithermal-related, gold-silver-zinc system characterized by continuous zones of disseminated and breccia-hosted, bulk tonnage-style mineralization. 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 also defining additional drill targets across the entire land package through systematic exploration programs.
