SUN SUMMIT'S EXTENSIVE DATA REVIEW IDENTIFIES MULTIPLE NEW HIGH-GRADE GOLD-SILVER TARGETS AT THE JD PROJECT

Sun Summit Minerals Corp. has defined additional targets across the highly prospective Finn to Creek corridor, a significant gold-silver mineralized trend on the recently optioned, road-accessible JD project in the Toodoggone gold-copper mining district in north-central British Columbia.

Highlights:

• Multiple priority drill targets defined through extensive data review: A continuing comprehensive review and compilation of property-wide historical geochemical data has resulted in the definition of multiple new target areas that warrant considerable follow-up work, including drilling.
• Zones of widespread high-grade gold-silver mineralization: Selected assay highlights from historical rock samples in the Finn to Creek corridor include:
  • Schmitt zone: 326 grams per tonne (g/t) gold (Au) with 1,535 g/t silver (Ag) (sample 18736) and 64.5 g/t Au with 6,151 g/t Ag (sample 18737);
  • Wolf zone: 79.2 g/t Au with 30.5 g/t Ag (sample 26070) and 35.4 g/t Au with 44.8 g/t Ag (sample 1710255);
  • MVT zone: 14.7 g/t Au with 809 g/t Ag (sample 18458) and 11.4 g/t Au with 35.2 g/t Ag (sample 1713456);
  • JD West: 14.8 g/t Au with 910 g/t Ag (sample 1710529) and 14.1 g/t Au with 1,601 g/t Ag (sample 18747);
  • Finn zone: 47 g/t Au with 17.5 g/t Ag (sample VF-24) and 27.3 g/t Au with 61.4 g/t Ag (sample I552528).
• Broad zones of gold-in-soil anomalism: Gold anomalies, with many samples greater than one g/t Au, are spatially associated with local zones of outcropping epithermal-related gold-silver mineralization. Many of these coincident anomalies have not been previously drill-tested and represent high-priority areas for future exploration programs.
• 2024 exploration program currently being finalized: Future fieldwork is anticipated to include geological mapping, soil and rock geochemical surveys, geophysical surveys, as well as significant drilling across multiple targets.

Note: Assay results are historical and have been compiled from sources believed to be accurate. Grab samples are selective in nature and the resulting assays may not be representative of all mineralization across the project.

"The primary goal of our data compilation effort is to generate walk-up, high-potential drill targets," stated Sharyn Alexander, Sun Summit's president. "Ongoing review of historical data, much of which has never been digital, outlines the presence of outcropping zones of high-grade mineralization from rock samples spatially associated with broad and widespread gold-in-soil anomalies. This coincident relationship provides us confidence to prioritize many of the numerous untested anomalies across the project area, specifically along the Finn to Creek corridor, a highly prospective area of largely untested ground. The fact many of these anomalies are defined by soils samples greater than one g/t gold strongly supports the high prospectivity of the targets. Further details of the upcoming field program at JD will be announced as the data compilation efforts come to a close."

The JD project comprises over 15,000 hectares of contiguous mineral claims in the prolific Toodoggone gold-copper mining district in north-central British Columbia. The project is host to high-grade, epithermal-related, gold-silver systems and porphyry-related copper-gold systems, and lies just north of the Kemess Cu-Au (copper-gold) mining camp.

Target generation

The recent review of surface geochemistry builds on the historical drill data compiled from the Finn and Creek zones (see Feb. 1, 2024, and Feb. 12, 2024, news releases) that anchor each end of the expanded 4.5 km long Finn to Creek gold-silver corridor, host to numerous epithermal-related vein and breccia systems. Priority targets along this corridor, based on surface geochemistry, are as shown in the table entitled "Selected grab/float (rock) sample highlights from historical exploration programs across the JD project."

• Finn -- the Finn gold-in-soil anomaly spans 770 metres by 350 metres and is spatially coincident with previously drill tested, near-surface epithermal-related gold-silver mineralization (for example, 35.7 m of 7.3 g/t Au (JD95-047) and 22 m of 12.5 g/t Au (JD95-064), see Feb. 1, 2024, news release). The relationship between soil geochemical anomalism, up to 12.2 g/t Au, rock chip samples with grades up to 47 g/t Au with 17.5 g/t Ag, and subsurface high-grade gold mineralization, suggests that other gold soil anomalies are relatively in situ. Of the eight gold-in-soil anomalies identified in this release, only the Finn zone anomaly has been sufficiently drill tested with reasonably close-spaced drilling.
• Schmitt -- the Schmitt coincident soil and rock geochemical anomaly is centred 1.4 km west of the Finn anomaly. The zone consists of a boulder train of siliceous breccias and banded quartz veins that have historically yielded assays of up to 326 g/t Au with 1,535 g/t Ag, and 64.5 g/t Au with and 6,151 g/t Ag. The target has not been adequately drill tested or trenched (only six short drill holes from the early 1980s), and the bedrock source of the high-grade boulders remains unknown. The Schmitt target is prioritized for systematic follow-up work which may include geological and structural mapping, rock-chip sampling, and follow-up drilling.
• Wolf -- the Wolf gold-in-soil anomaly (up to 8.5 g/t Au), centred 1.6 km west of the Finn zone, is spatially associated with zones of outcropping high-grade gold mineralization reportedly exposed over an area of 90 metres by 50 metres. Gold mineralization is hosted in numerous discrete zones (up to three metres in apparent width) of strongly oxidized hydrothermal breccias and local vein stockwork zones where rock chip samples of up to 79.2 g/t Au with 30.5 g/t Ag, and 35.4 g/t Au with 44.8 g/t Ag, have been reported. The Wolf target has not been previously drill tested and warrants detailed follow-up.
• MVT -- the MVT gold-in-soil anomaly is centred one km west of the Finn anomaly, where historical soil sampling defined a strongly anomalous 370 metres by 200 metres target. The soil anomaly (samples up to five g/t Au) is spatially coincident with grab samples of up to 14.7 g/t Au and 809 g/t Ag. The MVT target has not been previously drill tested and represents a priority area for future drill programs.
• JD West -- the JD West gold-in-soil geochemical anomaly covers the gap between the Finn and Schmitt zones, 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 Feb. 1, 2024, news release). The anomaly is spatially associated with the historical Ag-carbonate zone, where grab sampling from quartz-carbonate breccias, hosted along steeply dipping, north-striking normal faults, yielded up to 14.1 g/t Au with 1,601 g/t Ag. Geological mapping focused on examining structural controls is warranted to better define the extent of high-grade gold and silver mineralization across the JD West target.
• Buff -- the Buff gold-in-soil anomaly covers an area just north of the Finn zone, beyond a broad gossan centred on an east-draining creek. Previous drilling at the Buff zone targeted the northern dip-extent of Finn zone mineralization at depth (see Feb. 1, 2024, news release). The presence of soil samples with results up to 1.7 g/t Au, and up to 17.7 g/t Au with 47.4 g/t Ag in rock chip samples, suggests the Buff zone may also host a near-surface gold target north, and stratigraphically above and/or offset from the Finn zone. This area therefore warrants geological mapping and rock-chip sampling to better define potential drill targets across the broad anomaly.
• Creek -- the high-grade Creek target, on the western extent of the Finn to Creek corridor, contains poorly defined, structurally controlled high-grade gold mineralization (for example, four m at 61.2 g/t Au (CZ97-008), see Feb. 12, 2024, news release). Soil sampling across the Creek zone with results up to 7.5 g/t Au and grab samples up to 5.7 g/t Au, suggests the potential for locally concealed and near-surface, gold mineralization. Besides drilling, additional work at the Creek zone will consist of systematic geological and structural mapping, and rock-chip sampling. An induced polarization (IP) geophysical survey is also planned across the target area.

Note: drill intervals are downhole core lengths. True widths are unknown.

These targets, together with targets defined through historical drill data review at the Finn and Creek zones (see Feb. 1, 2024, and Feb. 12, 2024, news releases), will form the framework for target prioritization for the future 2024 exploration program, set to commence in early summer. Continuing data compilation is now focused on merging and reprocessing existing airborne and ground geophysical datasets. 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.
