Sun Summit Identifies Multiple Zones of High-Grade Gold and Silver Mineralization in Historical Trenching at the JD Project in B.C.

Vancouver, May 28, 2024 - Sun Summit Minerals Corp. (TSXV: SMN) (OTCQB: SMREF) is pleased to announce that a review of historical trench data has confirmed a significant gold-silver mineralized trend along the highly-prospective Finn to Creek corridor on the road accessible JD Project in the Toodoggone gold-copper mining district in north-central British Columbia.

Highlights:

• Historical trenching results further demonstrate the presence of near-surface, high-grade gold and silver mineralization: An ongoing review and compilation of historical trenching data across the Finn to Creek trend has further supported the potential for significant near-surface mineralization.

• Continuous zones of near-surface, high-grade gold and silver mineralization: Historical trenches were designed to test strong soil anomalies and many were reportedly mineralized along the entire length of the excavation. Selected interval highlights¹ include:

  • Finn Zone:
    • 45.5 metres at 6.1 g/t Au including 5.5 metres at 36.4 g/t Au (trench 88-78)
    • 10.0 metres at 12.0 g/t Au including 6.0 metres at 19.4 g/t Au (trench 88-70)
    • 31.4 metres at 3.7 g/t Au including 5.0 metres at 12.0 g/t Au (trench 88-76)
    • 106 metres at 2.2 g/t Au including 17.0 metres at 8.0 g/t Au (trench 88-67)
    • 24.9 metres at 4.5 g/t Au including 3.0 metres at 15.98 g/t Au (trench 83-01)
  • JD West Zone:
    • 5.0 metres at 5.6 g/t Au with 296 g/t Ag (trench 88-33)
    • 3.0 metres at 3.2 g/t Au with 631 g/t Ag (trench 88-35)
      
      

• Complex epithermal environment indicates high potential for prospectivity: Vein-hosted and breccia-hosted, high-grade mineralization has been exposed in numerous trenches with different silver to gold ratios suggesting high-structural complexity, multiple phases of mineralization, and therefore strong prospectivity.

• 2024 exploration program to commence shortly: The approaching field work will include significant drilling across multiple targets, as well as geological and structural mapping, soil and rock geochemical surveys, and geophysical surveys.

¹ Assay results are historical and have been compiled from sources believed to be accurate.

"As we wrap up this phase of data compilation, it is becoming even more apparent that the JD Project has significant potential to host multiple zones of near-surface, high-grade gold and silver mineralization," stated Sharyn Alexander, Sun Summit's President. "Trenching programs in the 1980s were focused on evaluating strong soil anomalies, which lead to the discovery of the Finn, MVT and JD West zones. The Finn zone has been drill tested, however, many areas remain open for expansion and more importantly, the JD West and MVT zones have yet to be fully drill tested. These targets, together with the high-grade Wolf, Schmitt and Creek targets, are priority areas for our upcoming field program, which we look forward to commencing in the near term."

Target Generation

The recent review of historical trenching data at JD builds on the historical drill data, soil and rock geochemical data compiled from the Finn to Creek gold-silver trend (see February 1, 2024, February 12, 2024 and May 2, 2024 news releases), host to numerous epithermal-related vein and breccia systems. Many of these zones of high-grade gold and silver mineralization were discovered over the course of multiple trenching programs in the 1980's. The true thickness of the trenched zones is unknown and intervals are channel and/or chip sample lengths.

Data sources are referenced below. The true thickness of the trenched zones is unknown and intervals are channel and/or chip sample lengths.

• Finn - Near-surface, epithermal-related gold and silver mineralization at the Finn zone, discovered in historical trenching, is spatially coincident with a broad 770 by 350 metre gold-in-soil anomaly (see May 2, 2024 news release). This coincident surface geochemical anomaly was subsequently drill-tested in the 1990's, which yielded strong intervals of breccia-hosted gold-silver mineralization (e.g., 35.7 m of 7.3 g/t Au (JD95-047²) and 22.0 m of 12.5 g/t Au (JD95-064²), see February 1, 2024 news release). The structural relationship between this high-grade core of the Finn Zone (e.g., 5.5 m of 36.4 g/t Au in trench 88-78, Figure 1) and the western-extent of surface mineralization (e.g., 12.0 metres of 14.3 g/t Au in trench 83-11, Figure 1), formerly known as the Gumbo and Gasp zones, is not well understood. Follow-up work, focussed on re-assessing structural controls at the Finn zone, is ongoing as new historical information is reviewed and compiled. These areas will be a focus for systematic structural mapping and sampling in the upcoming field program.

• JD West - The JD West target covers the gap between the Finn and Schmitt zones (Figure 1) where the potential strike-extension of the prospective, low-angle fault at the Finn zone is locally exposed in historical trenches and has been drill tested in several, widely-spaced, shallow holes (see February 1, 2024 news release). Historical trenching was initially focused on evaluating a broad silver-gold soil anomaly (see May 2, 2024 news release) and led to the discovery of the north-striking and steeply dipping silver-bearing Ag-Carbonate vein (e.g., 3.0 m of 3.2 g/t Au with 631 g/t Ag in trench 88-35, Figure 1). Based on the high-Ag:Au ratio of these north-striking veins it is interpreted that these systems may represent a different pulse of epithermal-related fluids compared to the gently-dipping, low-Ag:Au ratio Finn-style mineralization. Geological mapping focused on examining structural controls and relationships between different styles of mineralization in the JD West and peripheral areas will be prioritised during the upcoming field program with the goal of defining robust drill targets for follow-up drill testing.

• MVT - Historical trenching and rock-chip sampling across the strong MVT gold-in-soil anomaly (see May 2, 2024 news release) returned multiple zones of local gold mineralization (e.g., 8.0 m of 2.1 g/t Au in trench 88-39). Further work, including geological mapping and potential induced polarization (IP) geophysics, is required at MVT to better define the source and the orientation(s) of potentially concealed mineralized vein(s) responsible for the highly-anomalous soil samples, including the possibility of north-striking veins (e.g., JD West) which may have been missed with north-northeast oriented trenches (Figure 1). The results of upcoming field work could lead to the first drill test of the MVT target.

² Note trench intervals are composite channel and/or chip samples. True widths are unknown.

The targets identified through data compilation will be ranked and prioritised for drill testing in the upcoming 2024 exploration program, set to commence in early summer. Details of the upcoming exploration program will be released once compilation efforts are completed and budgets are finalized.

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.
