Dryden Gold Expands the Gold Rock Camp with High-Grade Discoveries at Mud Lake

Rhea-AI Summary

Dryden Gold (OTCQB: DRYGF / TSXV: DRY) reported results from a first-pass, three-hole drill program at the Mud Lake target in the Gold Rock Camp on November 25, 2025. Highlights include a high-grade intercept of 43.10 g/t Au over 0.50 m (76.50–77.00 m) and a surface sample of 93.00 g/t Au in North Mud Lake. Mapping and sampling suggest a potential ~1-kilometer mineralized footprint with shear-hosted quartz-feldspar porphyry targets. The company notes true widths are unknown and further drilling and permitting are planned for follow-up testing.

Positive

• High-grade drill intercept: 43.10 g/t Au over 0.50 m
• Surface sample peak: 93.00 g/t Au
• Mapping suggests ~1 km mineralized footprint at Mud Lake

Negative

• Reported intervals are drilled lengths; true widths unknown
• Initial program limited to three drill holes plus one additional hole
• Key shear (Pincher) does not outcrop and requires drilling

Vancouver, British Columbia--(Newsfile Corp. - November 25, 2025) - Dryden Gold Corp. (TSXV: DRY) (OTCQB: DRYGF) ("Dryden Gold" or the "Company") is pleased to announce results from its first pass 3-hole exploration program at the Mud Lake Target Area ("Mud Lake") in the Gold Rock Camp. Mud Lake is located 2 kilometers northeast of the main Gold Rock target area along the prolific Manitou-Dinorwic Deformation Zone ("MDdz"). The objective of the step-out drilling at Mud Lake was to confirm the periodicity (or repetition) of the high-grade gold structures controlled by the MDdz along its 20-kilometer strike in the Gold Rock Camp. With this successful step-out, the Company will continue to develop addition targets in the Gold Rock Camp. Summary video link.

Highlights:

• Quartz vein intersects as high as 43.10 g/t gold over 0.50 meters (similar to be the Big Master) from 76.50m to 77.00m depth (Table 1, Table 3);

• Surface sampling on high-grade a shear zone of 93.00 g/t gold (similar to be the Elora) (Table 2);

• Additional mapping and sampling indicates potential at Mud Lake for a 1-kilometer mineralized footprint similar to the Gold Rock target area.

Trey Wasser, CEO of Dryden Gold commented, "One of our four major objectives in the 2025 exploration program was to validate our theory of periodicity of deposits in the Gold Rock Camp. Our early success at Mud Lake confirms that the geological setting could support multiple sub-parallel, gold-bearing structures. This type of structural repetition is the foundation of many high-performing gold camps and signals meaningful upside for ongoing exploration. In hockey terms, these Mud Lake results, combined with our success in expanding the Gold Rock target area, our early exploration success at Sherridon and Hyndman, would be considered a 'haul' scored by Dryden Gold in 2025."

Mud Lake was first tested through the Company's 2024 mapping campaign. Structural controls and surface expression at Mud Lake showed potential for similar mineralization to the Big Master and Elora Gold Systems in the Gold Rock target area. The mapping program from 2025 followed the mineralized trend further north where a sizable shear zone intersects favourable host rocks (Figure 1).

The geological interpretation for the expanded Mud Lake footprint is still on-going. Initial findings from the mapping and drill program show a flexure or bend in the mineralized trend. This geometry is common in shear zone systems and had been hypothesised by the geology team. The 2025 mapping confirmed this geometry where weather resistant quartz-feldspar porphyry ("QFP") rocks outcropped hosting mineralization. The 2024 mapping program and 2025 drill holes targeted the southern portion of Mud Lake where narrow vein structures outcrop and have a very similar appearance to the Big Master system at Gold Rock. Samples from North Mud Lake indicate broader mineralization throughout the QFP (Figure 2). The geology team theorizes that the Pincher deformation zone may act like the Elora Shear at Gold Rock and host wider zones of mineralization. Unfortunately, like the Elora Shear, the Pincher deformation zone does not outcrop and will have to tested through drilling. The geology team will continue to analyze the data collected from the summer Mud Lake program to plan permitting and further testing at Mud Lake.
