TDG Outlines Multiple Kilometre-Plus-Scale Target Areas within Northwest Structural Corridor from the Aurora Complex

Geochemical and geophysical results expand known target footprints and support district-scale exploration potential across TDG’s 100%-owned Toodoggone mineral claims

VANCOUVER, British Columbia, Sept. 23, 2026 (GLOBE NEWSWIRE) — TDG Gold Corp. (“ TDG ” or the “ Company ”) (TSXV: TDG | OTCQX: TDGGF) reports that interim results from its 2026 regional exploration program have expanded and better-defined exploration target areas at Baker–North Quartz, Black Gossan and Price–Trident. Each target area is characterized by kilometre-plus-scale geophysical responses or groupings of responses, located within TDG’s 100%-owned mineral claims in a corridor stretching northwest from Amarc-Freeport’s Aurora gold-rich copper porphyry discovery in BC’s Toodoggone District.

The results extend the exploration footprint beyond historical showings and support evaluating multiple potential mineralizing centres across an approximately 15-kilometre prospective corridor extending northwest of the Aurora Complex ( Figure 1 ). Integrated soil geochemistry has identified additional gold- and copper-anomalous areas, the potential of which is supported by geophysical anomalies, providing a common technical basis for comparing and prioritizing opportunities across the corridor.

Remaining 2026 fieldwork, outstanding assays and final geophysical interpretations will support target ranking, with emphasis on geological setting, geochemical coherence, potential for near-surface mineralization and support from multiple independent datasets.

“The significance of this work is the combination of scale and multiple opportunities within one wholly-owned corridor,” said Paul Geddes, TDG’s SVP Business Development & Strategy. “A consistent technical framework allows us to compare those opportunities and identify where the strongest evidence comes together. That provides a better basis for selecting where to focus the next stage of exploration.”

The 2026 program integrates soil geochemistry, direct-current induced polarization (“DCIP”) and passive magnetotellurics across TDG’s 100%-owned mineral claims covering an area that encompasses TDG’s mineral-resource-stage Shasta project ( PEA initiated June 2026 ) , Aurora West and Baker, and extends as far north as the Saunders target (Figure 1) . It represents the first comprehensive assessment of the broader corridor using consistent geochemical and geophysical coverage, looking beyond historical showings to determine whether they represent isolated occurrences or surface expressions of larger mineralized systems.
