Dryden drilling adds structures across Ontario’s Gold Rock system

Dryden Gold reported new drill assays from its Gold Rock system in northwestern Ontario on October 22. The company says the system now comprises 15 mineralized structures across more than one kilometre in width and two kilometres of strike, compared with three widely spaced parallel structures when the initial program was completed in 2024. Dryden describes the system as open in all directions. These are company interpretations of drilling and geology, not a current mineral-resource estimate.

The reported intercepts span several parts of Gold Rock. Hole DGR-078 returned 8.57 grams of gold per tonne over 1.10 metres in a newly recognized structure less than 20 metres from known mineralization. Hole DGR-087, a step-out more than 400 metres along strike, returned 3.23 g/t over 1.60 metres. In the Elora Hanging Wall area, the company reported 12.62 g/t over 1.85 metres, including 54.40 g/t over 0.40 metres, at approximately 160 metres true depth.

Dryden says its interpretation has evolved from a narrow, high-grade vein model toward a broader system with several styles of gold mineralization. These include free gold in quartz veins with lower-grade halos, wide shear structures containing disseminated sulphides, and sheared basalts. The company said new parallel structures could extend mineralization within the existing footprint. That geological interpretation is the context for its focus on the “Gap,” where drilling remains sparse and the current campaign is intended to add definition.

The three highlighted intercepts describe downhole drill lengths, and the release says the reported composites are uncapped. Their downhole lengths should not be read as true widths; the source does not provide true-width estimates for these intervals. The Elora Hanging Wall intercept is separately located at about 160 metres true depth. These distinctions matter because a measured drill interval is the length of core carrying the reported grade, while the geometry of the mineralized structure may cut the hole at an angle.

The results also combine infill and step-out information. DGR-078 is close to known mineralization and identifies another structure within the system. DGR-087 tests a position farther along strike, more than 400 metres from the existing drilling reference point described by the company. The Elora Hanging Wall interval adds another high-grade result from a named area. Together, they support Dryden’s account of multiple structures, but the release does not provide a revised resource calculation or demonstrate economic mineability.

Gold Rock is part of Dryden’s land position in the Dryden District of Ontario. The company says the broader Manitou-Dinorwic deformation zone offers about 50 kilometres of potential strike across its holdings, while this release concerns the Gold Rock system specifically. Regional length is an exploration setting, not a measure of continuous mineralization. The 15 structures and dimensions cited for Gold Rock are also company-defined geological descriptions, not classified resources.

Dryden President Maura Kolb said the current objective is to infill areas where drilling is sparse, particularly the Gap, and to continue testing the system. The company says it has encountered additional mineralized structures in nearly every exploration hole. Such statements describe the issuer’s drilling interpretation; individual intersections remain localized observations until continuity and grade distribution are assessed through further drilling and technical work.

The release’s assay procedures include laboratory analysis and quality-control samples, and the technical content was reviewed by the company’s qualified person. The data block lists only the three highlighted grade-and-length pairs. It does not convert downhole lengths into true widths or treat them as resources, reserves or production. The reported assays are exploration results from specific holes and do not by themselves establish tonnage, continuity, recoverability or a mine plan.
