Dryden Gold Corp. [TSX-V: DRY) (OTCQB: DRYGF] is pleased to provide a drill program update at its Gold Rock project. The Company has now drilled 6,084 meters of the planned 15,000-meter program and would like to update investors of its progress and plans to follow-up on Hole KW-25-003 that returned 301.67 g/t gold over 3.90 meters including 1,930 g/t gold over 0.60 meters.

The Company remains committed to a data-driven approach to drill targeting and will continue to incorporate all available geological, structural, and geochemical data into its drill planning. Drill targets will be dynamically prioritized to allow sufficient time for logging oriented core and integrating new structural interpretations into the design of subsequent holes. To date, Dryden has targeted the Jubilee Zone, Laurentian Mine area and the Intersection Target (Figure 1). After encountering the new high-grade Hanging Wall Zone while drill testing the Jubilee Zone, the geology team has developed a new strategy to drill test both zones more strategically.

At Gold Rock, the Company is targeting Archean Lode-Gold style mineralization which is strongly structurally controlled. Dryden has been working to improve the understanding of the deformation history of the region as it relates to the emplacement of the gold mineralization. The Company has recently uncovered a third gold bearing structural trend (the “D3 Structure”, Figure 1) that has now been integrated into targeting and drill testing. (structural video)

President of Dryden Gold, Maura J. Kolb stated “In order to best target high-grade gold mineralization, the geology team is focused on unlocking the structural history to drive targeting during the drill campaign. Through the drill program and mapping campaign, the geology team has collected structural measurements to fine-tune our exploration model. The team continues to adjust the drill plan as new data is collected, helping us have the best chances for intersecting high-grade gold mineralization at the most effective cost.”

HW Zone

With the discovery of the high-grade HW Zone (see press release dated May 7, 2025) the Company will follow up this target with step out holes near surface based on the up-plunge projection of the mineralization and using historical drill data to interpret the potential footprint of the new zone. In addition, the team is planning holes that follow up this target around 200 meters depth where the initial hole KW-25-003 intersected the significant mineralization.

Jubilee Zone

The Company begun testing the Jubilee Zone in 2024 with favourable results. Testing on this high-grade zone to date has shown a 100–150-meter strike length with significant down plunge potential. Using the structural controls and measurements from the oriented core, the geology team continues to test Jubilee at depth of 300-500 meters below surface. Based on the new structural interpretation, the Jubilee Zone has a more southerly trending plunge than initially interpreted. Hole KW-25-003, which also intercepted the high-grade HW Zone and Hole KW-25-002, were both designed to test the northern extent of the Jubilee Zone plunge. The geology team has now adjusted its structural interpretation and established the new targets to better encounter the more southerly high-grade plunge at Jubilee (Figure 3).

Laurentian Mine

The Company has begun to test the Laurentian Mine area. This mine operated in the early 1900’s producing 20k tonnes at an average grade of 14 g/t gold (1971 Ferguson). The reported depth of the mine was 140 meters below surface. The geology team will be targeting this zone below the historical mine operations as well as drill testing hanging wall and footwall potentially mineralized zones. The historical infrastructure continues to be “ground-truthed” by the geology team. Dryden will test this target in small phases and adjust the drill plan with each new observation.

Intersection Target

Dryden is testing the structural thesis incorporating the newly defined D3 structure, on the new Intersection Target (Figure 1 and 3). Based on the geophysical data interpretation and geological mapping completed by Dryden, this drill target is based on the intersections of the three structural trends. There are a few historical drill holes near this target that show prospective mineralization. The Company will test this target with a first pass, then follow up if the results are favourable.

Analytical Laboratory and QA/QC Procedures

The Company is drilling NQ size core. Samples are cut in half, with half going to the lab for analysis and half kept as a record. All sampling completed by Dryden Gold Corp. within its exploration programs is subject to a Company standard of internal quality control and quality assurance programs which include the insertion of certified reference materials, blank materials, and a level of duplicate analysis. Drill samples from the 2024 and 2025 program were sent to Activation Laboratories, with sample preparation and analysis in Dryden, where they were processed for gold analysis by 50-gram fire assay with an atomic absorption finish and over limits determined by Fire Assay with a gravimetric finish. Select samples were analyzed using metallic screens. Activation Laboratories systems conform to requirements of ISO/IEC Standard 17025 guidelines and meets assay requirements outlined for NI 43-101.
