SUN SUMMIT COMMENCES INAUGURAL DRILL PROGRAM TARGETING HIGH-GRADE GOLD MINERALIZATION AT THE JD PROJECT

Sun Summit Minerals Corp. has begun its inaugural exploration campaign at the JD project, north-central British Columbia. The JD project, located in the prolific Toodoggone gold-copper mining district, spans 15,000 hectares and hosts numerous underexplored, epithermal-related gold-silver and porphyry-related copper-gold targets.

Highlights:

• Inaugural drill program has started: Up to 3,000 metres of drilling, targeting near-surface, high-grade, epithermal-related gold-silver mineralization within the Finn to Creek corridor has commenced.
• Targeting high-grade gold mineralization: The first five planned drill holes at Creek will target extensions of high-grade gold mineralization where limited drilling in 1997 and 1998 returned intercepts such as 22.0 metres of 11.7 grams per tonne (g/t) gold (Au), including four metres of 61.2 g/t Au from drill hole CZ97-008.
• Comprehensive exploration program is ramping up: In addition to drilling, other complementary exploration activities include:
  • A 20-line kilometre induced polarization (IP) geophysical survey has been completed across the Creek zone and potential deeper targets to the northeast. Data review has commenced.
  • A grid-based, 2,000-sample soil geochemical survey, designed to investigate the footprints of multiple target areas, is nearing completion.
  • Detailed structural and geological mapping focused on the Finn to Creek corridor is continuing.
  • A project-wide lidar survey has been completed and data review has commenced.

"We are very pleased to see the drill turning at the JD project," stated Sharyn Alexander, Sun Summit's president. "Hard work over the last several months has led to this first exciting milestone in our exploration program. We have designed our summer program to investigate the gold potential of several high-priority targets through drilling as well as complementary project-wide geophysical, geological and geochemical surveys. Results from all activities will set the foundation for continued exploration across multiple target areas. We look forward to keeping the market informed on our exploration progress this summer."

Drill commencement and program update

The summer 2024 drill program first aims to explore potential extensions of sulphide-rich, structurally controlled, high-grade gold mineralization intersected in historical drilling at the Creek zone. Limited drilling in 1997 and 1998 at Creek returned intervals such as 22.0 metres of 11.7 g/t Au, including four metres of 61.2 g/t Au from drill hole CZ97-008 (see Feb. 12, 2024, news release). The first five planned drill holes comprise stepouts from areas of known mineralization.

The multidisciplinary program will also target gold mineralization across the 4.5-kilometre Finn to Creek corridor and the Belle target areas. Exploration activities recently completed and still underway include:

• IP geophysical survey: A 20-line kilometre IP survey has been completed over the Creek zone, as well and potential proximal yet deeper targets to the northeast, where outcrop exposure is sparce. Data review and interpretation is currently under way.
• Soil geochemical survey: Up to 2,000 soil samples will be collected across the Creek and Belle zones. At Creek, sampling is designed to infill gaps in previous geochemical surveys in 2013 as well as to confirm results of historic surveys from the 1980s. At Belle, centred 2.7 kilometres (km) south of the Finn zone, grid-based soil sampling is designed to investigate the geochemical footprints of epithermal-related gold mineralization identified in historic trenching.
• Structural and geological mapping: Detailed mapping, focused on the Finn to Creek corridor, is continuing and designed to refine the geological model, as well as identify significant structural features, particularly at the Creek zone where the orientation of gold-bearing structures is not well understood.
• Lidar and aerial photography: A property-wide lidar and aerial photography survey with submetre accuracy has been completed. This survey will provide detailed terrain models essential for accurate geological interpretation and project planning. Data review has commenced.

Results from all initial exploration activities will be used to rank and prioritise the next set of drill holes in the Finn to Creek corridor.

He has not been able to verify the historical exploration data disclosed, including sampling, analytical and test data, underlying the technical information in this news release since such data is historical and the original drill core is not readily available. Technical information contained in this release is historical in nature and has been compiled from public sources believed to be accurate. The technical information has not been verified by Sun Summit and may in some instances be unverifiable dependent on the existence of historical drill core and grab samples.

Community engagement

Sun Summit is engaging with first nations on whose territory its projects are located and is discussing their interests and identifying contract and work opportunities, as well as opportunities to support community initiatives. The company looks forward to continuing to work with local and regional first nations with ongoing exploration.
