SUN SUMMIT DRILLS 122.5 METRES OF 2.1 G/T GOLD INCLUDING 20.0 METRES OF 10.0 G/T GOLD AT THE CREEK ZONE, JD PROJECT, TOODOGGONE DISTRICT, B.C.

Sun Summit Minerals Corp. has released drill results from its fourth hole drilled during its inaugural exploration program at the JD project in the Toodoggone district, north-central British Columbia.

Hole CZ-24-004 returned one of highest-grade intervals drilled to date at the Creek zone, 121.0 grams per tonne (g/t) gold over 1.52 metres, as well as intersected consistent gold mineralization over 122.53 metres from surface. These results continue to demonstrate the presence of both high-grade and bulk-tonnage gold mineralization in this underexplored target area.

Highlights:

Hole CZ-24-004 intersected a broad zone of near-surface, continuous gold mineralization punctuated with high-grade veins:
- 122.53 metres of 2.11 g/t gold, including:
  - 20.0 metres of 10.01 g/t gold;
  - 4.04 meters of 46.78 g/t gold;
  - 1.52 metres over 121.0 g/t gold.
Assay results build on previously announced drill results from the Creek zone: These results further demonstrate the presence of significant high-grade gold mineralization, as well as near-surface disseminated mineralization previously unrecognized due to selective sampling in historical drill programs.
Additional assay results pending: Assays from the remaining eight drill holes (1,674 metres) are pending.
Final results pending from numerous project-wide surveys: Results from soil and rock geochemical surveys together with final data products from an induced polarization (IP) geophysical survey and reprocessing of historic geophysical data are pending.

Sharyn Alexander, president of Sun Summit Minerals, stated: “The 2024 drill program continues to deliver significant results at the Creek zone. Hole CZ-24-004, our fourth hole of this year’s program, further confirms the potential for both high-grade and bulk-tonnage-style gold mineralization and supports our initial thesis that selective sampling by previous operators missed the bulk-tonnage gold potential. The high-grade vein-hosted interval of four metres of 46.8 g/t gold, including 1.52 metres of 121.0 g/t gold, is significant and deserves further drill testing to better understand trends and structural controls. We look forward to sharing additional results from our summer program as they become available.”

Drill hole CZ-24-004

Hole CZ-24-004 was collared from the same pad as CZ-24-003 (95.50 metres of 0.70 g/t gold, including 34.0 metres of 1.32 g/t gold and including 18.0 g/t gold over 0.50 metre, see Sept. 19, 2024, news release) but drilled toward the southwest. The high-grade interval of 4.04 metres of 46.78 g/t gold in CZ-24-004 extends the important zone of high-grade gold mineralization, central to the Creek zone, approximately 40 meters along strike to the north. Results from this hole, highlighted by 122.53 metres of 2.11 g/t gold, also further demonstrates the presence of previously unrecognized, near-surface bulk-tonnage-style disseminated gold as most historical holes drilled at the Creek zone were not continuously sampled. The lack of systematic sampling in the late 1990s resulted in a failure to recognize the bulk-tonnage potential of the target area.

Similar to the first three reported drill holes (see Sept. 19, 2024, news release), CZ-24-004 intersected a bedded sequence of volcaniclastic and intermediate volcanic 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 breccias with strong potassium feldspar alteration halos. Vein-hosted sulphides include pyrite, sphalerite, plus or minus chalcopyrite, and galena. Bulk-tonnage mineralization is associated with selectively pervasive epidote-chlorite-pyrite alteration, proximal to vein-associated potassic alteration.

Drill program

The first five holes of the 2024 exploration program were drilled on the western extent of the 4.5-kilometre-long, target-rich Finn to Creek corridor. Results from holes CZ-24-001, 002 and 003 were released on Sept. 19, 2024, results from hole CZ-24-004 are released here, and results from hole CZ-24-005 are pending. Over all, the drill program consisted of 2,537 metres of diamond drilling across 12 holes (see Sept. 5, 2024, news release).

At the Creek zone, drilling was primarily designed to build on results from past programs where previous drill holes were selectively sampled, vein orientation data was lacking and disseminated mineralization was not considered. The primary objective of the drilling at the Creek zone was to 1) confirm the presence of high-grade gold mineralization, 2) collect systematic downhole data to define a structural model to inform future drill programs and 3) investigate the presence of disseminated mineralization by continuously sampling from collar to bottom of hole.

Assays from the remaining drill holes, as well as surface sampling results, are pending and expected to 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 Lawyers exploration camp owned by Thesis Gold. Only Sun Summit and assigned Apex Geoscience field staff were allowed access to the core.

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 Langley, B.C., or Winnipeg, Man. Core samples were prepared using ALS standard preparation procedure PREP-31A which involves crushing the sample to 70 per cent less than two millimetres (mm), followed by a riffle split of 250 grams and then a pulverized split to better than 85 per cent 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 ultratrace element analytical method with low detection limits on key pathfinder elements.

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 over 10 parts per million (ppm) gold were reanalyzed by fire assay using a gravimetric finish on a 30-gram aliquot.

Overlimit samples were reanalyzed using an ore-grade, four-acid digestion and ICP-AES finish. Overlimits for key elements: samples with over 100 ppm silver, over 10,000 ppm copper, over 10,000 ppm lead and over 10,000 ppm zinc. 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.
