Highlights:
- Hole CZ-25-007 intersected a significant zone of near-surface, continuous gold mineralization punctuated with high-grade veins:
- 78.0 meters of 3.72 g/t gold from 30.0 meters down hole, including
- 12.0 meters of 8.55 g/t gold, and including
- 19.1 meters of 7.50 g/t gold
- The 78.0 meter interval contains multiple high-grade veins, some with fine visible gold, that returned 31.84 g/t gold over 1.0 meters, 54.40 g/t gold over 1.0 meters, 67.80 g/t gold over 0.90 meters and 98.80 g/t gold over 0.5 meters. These intervals clearly demonstrate the high-grade gold mineralization potential of the Creek Zone.
- Establishes a new zone of high-grade and disseminated mineralization: The upper 78.0 meter interval is in an area not previously tested by drilling and may represent a parallel zone of mineralization north of the main series of Creek Zone high-grade veins.
- Follow-up drilling planned: Based on the exceptional results from CZ-25-007, additional step-out holes are planned for this season to test the down-dip and northwest strike extent.
- Additional assay results pending: Assays from the remaining ten holes (3,340 meters) drilled at the Creek zone are pending.
"The first hole of this year's drill program at our JD Project in the significant Toodoggone District, represents the best hole drilled to date at the Creek Zone," said Niel Marotta, CEO of Sun Summit Minerals. "The hole intersected significant mineralization from 30 meters downhole. This interval is punctuated with multiple high-grade zones which supports the high-grade gold potential of the Creek Zone, typical of many Toodoggone gold deposits. We have planned additional holes to test the strike extent of this new zone of mineralization and are excited to move the drill rig back to the area in the coming weeks."

Drill Hole CZ-25-007
Hole CZ-25-007 was collared 75 meters to the north of hole CZ-24-004 (122.53 metres of 2.11 g/t gold including 4.04 metres of 46.78 g/t gold, see October 2, 2024 news release) and stepped out 100 meters west of hole CZ-24-005 (57.95 meters of 2.69 g/t gold including 19.50 meters of 7.31 g/t gold, see October 16, 2024 news release, Figure 1). The upper interval of strong disseminated and high-grade vein-hosted gold mineralization in CZ-25-007 (e.g., 78.0 meters 3.72 g/t gold, Table 1) is approximately 120 metes to the northwest of the upper interval in CZ-24-005 (Figure 2). Together, these intercepts may represent a new zone of mineralization that trends parallel to the main steeply-dipping northwest-striking vein-sets (e.g., 22.0 m of 11.7 g/t Au including 4.0 m of 61.2 g/t Au, in hole CZ97-0081). Further drilling is warranted to test the strike- and dip- extent of this parallel zone.
The upper interval in CZ-25-007 contains multiple high-grade veins and breccias (31.84 g/t gold over 1.0 meters, 54.40 g/t gold over 1.0 meters, 67.80 g/t gold over 0.90 meters and 98.80 g/t gold over 0.5 meters) within the broad zone of disseminated gold mineralization (Figure 3). Many of these higher-grade intervals contain fine visible gold (Figure 4). These intervals demonstrate the high-grade mineralization potential of the Creek Zone and support the strong prospectivity of the Creek Zone to the northwest in an area lacking drilling.
Hole CZ-25-007 intersected a bedded sequence of intermediate volcanic and volcaniclastic rocks interpreted to be a sequence within the McClair Member of the Early Jurassic Toodoggone formation. Higher-grade gold mineralization is hosted in epithermal-related and locally banded quartz-carbonate veins, veinlets and sulfide-cemented breccias with locally strong potassium feldspar alteration halos (Figure 3). Vein-hosted sulfides include pyrite, sphalerite, ± chalcopyrite and galena with some veins containing visible gold. Bulk-tonnage mineralization is associated with selectively pervasive sericite-chlorite-hematite alteration with disseminated pyrite, proximal to vein-associated potassic alteration (Figure 3).
Drill Program
Drilling in 2025 at the Creek Zone was designed to investigate the lateral and vertical extent of high-grade and bulk-tonnage gold mineralization (Figures 1 and 2). Over 3,700 meters across 11 drill holes at Creek have so far been completed. These holes were designed to systematically test the vein-controlling structures on 50 to 100 meter pierce-points covering a strike-length of over 800 meters and a down-dip extent of over 200 meters (Figures 1 and 2). Based on the result of CZ-25-007 step-out holes to the northwest are planned this season.
Assays from the remaining drill holes, as well as surface sampling results are pending and will be released as they are received and reviewed.

Quality Assurance and Quality Control
All drill core sample assay and analytical results have been monitored through the Company's quality assurance and quality control program (QA/QC). Drill core was sawn in half at Sun Summit's dedicated and secure core logging and processing facility at the JD exploration camp.
Half of the drill core was sampled and shipped by a bonded courier in sealed and secured woven polyester bags to the ALS Global preparation facilities in Kamloops, BC. Core samples were prepared using ALS standard preparation procedure PREP-31A which involves crushing the sample to 70% less than 2mm, followed by a riffle split of 250g, and then a pulverised split to better than 85% passing 75 microns.
Following sample preparation, the pulps were sent to the ALS Global analytical laboratory in North Vancouver, B.C. for analysis. ALS Global is registered to ISO/IEC 17025:2017 accreditations for laboratory procedures.
Drill core samples were analyzed for 48 elements by ICP-MS on a 0.25-gram aliquot using a four-acid digestion (method ME-MS61). This method is considered a "ultra trace element" analytical method with low detection limits on key pathfinder elements such as Ag, As, Sb, Se and Tl.
Gold was analyzed by fire assay on a 30-gram aliquot with an AES finish (inductively coupled plasma atomic emission spectroscopy - method Au-ICP21). Samples that returned >10 parts per million (ppm) gold were re-analyzed by fire assay using a gravimetric finish on a 30-gram aliquot (method Au-GRA21).
Overlimit samples (e.g. Ag, Cu, Pb & Zn) were re-analyzed using an ore-grade, four-acid digestion and ICP-AES finish. Over limits for key elements: samples with >100 ppm silver, >10,000 ppm Cu, >10,000 ppm Pb and >10,000 ppm Zn. In addition to ALS Global laboratory QA/QC protocols, Sun Summit implements a rigorous internal QA/QC program that includes the insertion of duplicates, certified reference materials (standards prepared by an independent lab) and blanks into the sample stream. A total of 38 QA/QC samples, including 21 standards, were inserted in the field, representing 14.2% of the overall sample stream. There were no significant issues identified in either the internal or external QA/QC samples.

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, Amarc Resource's AuRORA project, Centerra's Gold's Kemess East and Underground projects, as well as the past-producing Kemess open pit copper-gold mine (Figure 5).
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.
