Sun Summit's Creek Zone Delivers Record-Breaking Gold Strike: Fresh Drilling Uncovers 81 Meters Grading 4.80 g/t Gold with Exceptional High-Grade Intervals

Sun Summit Minerals has just released breakthrough drilling results that mark a significant milestone for the Creek Zone at its JD Project in Toodoggone District, British Columbia. The latest analytical data reveals some of the most impressive gold intercepts documented at this location to date.

The Main Event: A Zone That Keeps Delivering

The standout result comes from borehole CZ-25-021, which encountered a remarkable 81-meter zone of continuous gold-bearing mineralization beginning at 26 meters depth. What makes this truly noteworthy is the consistency: the entire interval averaged 4.80 g/t gold—but within that broader zone sits an even more concentrated section. A 14-meter sub-interval graded an exceptional 19.81 g/t gold, with ultra-high-grade pockets reaching 155 g/t, 101 g/t, and 30.6 g/t gold over individual meter-scale zones. These aren’t anomalies; they’re repeatable patterns within a structurally controlled corridor.

Building the Bigger Picture: System Scale and Open Potential

The 2025 drilling campaign systematically tested a northwest-trending fault zone measuring approximately 750 meters along strike, 300 meters across, and extending roughly 150 meters vertically from surface. The critical finding: every single borehole intersected gold mineralization. This consistency across 15 holes totaling 5,110 meters of drilling suggests the system has genuine area-wide potential rather than isolated pockets.

Hole CZ-25-016, positioned 460 meters southeast of the main discovery, yielded 17.0 meters of 2.32 g/t gold including 13.5 meters of 2.85 g/t Au—demonstrating the zone extends considerably beyond the initial high-grade intercepts. Roughly 100 meters to the northwest, hole CZ-25-018 encountered 15.0 meters of 1.39 g/t gold with a 10.5-meter core grading 1.75 g/t Au.

Structural Intelligence: Why This Discovery Matters

Sun Summit’s geological team developed a first-ever 3D structural model of the Creek Zone by integrating oriented drill core, surface mapping, and historical data. The key insight: two distinct fault systems trending 295-300° and 315-320°, both dipping ~50°, appear to control mineralization distribution. Their intersections correlate with high-grade vein concentrations and breccia-hosted gold bodies. This wasn’t obvious from previous drilling—historic holes were oriented in ways that often missed these critical structural intersections. The new model reveals that many of the highest-grade pockets occur at fault junctions where secondary and antithetic fractures create preferential pathways for ore-grade mineralization.

Grade Distribution and Vein Characteristics

Within the broader 81-meter zone, analysis reveals a 34-meter segment averaging 9.07 g/t gold, within which sits the exceptional 14-meter interval at 19.81 g/t. Individual quartz-carbonate veins with visible gold, sulfide-cemented breccias, and potassium feldspar alteration halos characterize the high-grade material. Disseminated pyrite mineralization within sericite-chlorite-hematite altered zones comprises the bulk-tonnage component. The vein-hosted sulfide assemblage—pyrite, sphalerite, ± chalcopyrite, and galena—shows the fingerprints of epithermal-style gold systems.

What’s Next: Metallic Screen Analysis and Continued Exploration

Sun Summit has submitted a substantial drill core collection from 2024-2025 work for metallic screen fire assay at ALS Global—a specialized analytical method that captures fine native gold particles more effectively than standard techniques. Results will establish optimal sampling workflows for high-grade intervals. Additionally, analytical results remain pending from four holes at the Finn Zone (3.5 km east of Creek) and two porphyry-focused holes at Belle South (8 km southeast), creating multiple drill-target opportunities across the property.

Management views the current data package as justifying continued down-dip and northeastern step-out drilling to test parallel mineralized structures that may have been overlooked by earlier exploration.

Project Setting and Regional Context

The JD Project encompasses over 15,000 hectares within the highly productive Toodoggone mining district, positioned alongside active projects from Thesis Gold, TDG Gold, and Centerra Gold. Proximity to the past-producing Kemess mine, combined with existing hydroelectric power infrastructure and established road networks, provides operational advantages for future development. Geological mapping confirms the area hosts both epithermal gold-silver systems and porphyry copper-gold potential—a favorable combination for district-scale discovery.
