TDG Continues Expanding Aurora West and Identifies New Porphyry Target VANCOUVER, British Columbia, Feb. 04, 2026 (GLOBE NEWSWIRE) -- TDG Gold Corp. (TSXV: TDG | OTCQX: TDGGF) (the “Company” or “TDG”) is pleased to report the remaining drilling results from the 2025 Phase I exploration program at the Aurora West Zone and Phase II (step-outs), part of TDG’s Greater Shasta–Newberry (“GSN”) Project located in the Toodoggone District of British Columbia. Results from the Company’s Phase I drilling program continue to demonstrate the emerging scale of the Aurora West Zone, now defined to approximately 1,000 metres (“m”) of strike, and extended at depth by the largest step-out completed to date (Table 1). Recent discovery of additional interpreted porphyry-style alteration approximately 600 m north of the Aurora Complex1 further supports the district-scale potential of TDG’s GSN Project (Figure 1). Continued Expansion Confirms the Emerging Scale of Aurora West Phase II (northern step-out) drill hole TDG25-020 (Table 2) represents the largest step-out completed to date at the Aurora West Zone and marks a meaningful expansion of Aurora West Zone mineralization. The hole intersected mineralized intervals grading 1.02 grams per tonne (“g/t”) gold (“Au”) and 0.43% copper (“Cu”) over 14.0 m, and 0.57 g/t Au and 0.29% Cu over 24.0 m hosting in a broader interval of 86.3 m of 0.49 g/t Au and 0.23% Cu. TDG25-020 was terminated within mineralized compositionally andesitic rocks. These results extend mineralization approximately 350 m down-dip from drill hole TDG25-012, which returned 1.30 g/t Au and 0.43% Cu over 88.0 m in a broader interval of 115.0 m grading 1.10 g/t Au and 0.38% Cu (Figure 2). Aurora West Zone has continuously identified approximately 1,000 m along a north–south trend, underscoring the size and continuity of the system identified during this initial phase of drilling. The mineralized interval in TDG25-020 returned diluted gold and copper grades due to the presence of interpreted late, mafic compositional dykes at this specific drill location. At this early stage of exploration, individual drill holes are expected to reflect local geological conditions, and nearby step-outs may encounter materially different results where intrusive dilution is less pronounced. New Porphyry Style Discovery North of the Aurora Complex Exploratory drilling has also led to the discovery of a substantial new area of interpreted altered porphyritic intrusions and associated quartz-sericite-pyrite (“QSP”) altered rocks an additional 600 m north of the currently defined and expanded Aurora West Zone, intersected in drill holes TDG25-014 and TDG25-018 (Figure 2). Intervals of anomalous gold and copper concentrations were encountered associated in addition to intersections of significant visual QSP alteration. The identification of broad intervals exhibiting strong alteration intensity represents increased exploration potential of the district. This discovery supports the interpretation that the Aurora Complex1 may form part of a much larger porphyry system, and that the broader GSN area remains highly prospective for additional discoveries. The geometry, extent, and relationship of this newly interpreted porphyry-style zone to the Aurora Complex1 has not yet been defined due to limited drilling in the area. Follow-up exploration drilling is being planned to further evaluate this new target. “What continues to stand out at our Aurora West Zone is the growing footprint of porphyry-style mineralization across our land holdings,” notes Fletcher Morgan, CEO of TDG Gold. “The identification of new porphyry-style bodies north of the Aurora West Zone reinforces our view that the Aurora West Zone and Shasta are part of a much larger system that is only beginning to take shape. Results from our step out drilling are consistent with early-stage exploration in a new geological environment and do not necessarily define the limits of the system as we have observed this hole-to-hole grade variability in other portions of the complex. With Aurora West Zone now extending approximately a kilometre, remaining open in multiple directions, and supported by the growth potential of the Shasta epithermal gold and silver resource, the district continues to develop as a strong candidate to support long-term regional mining and development plans.” Table 1: 2025 Phase I Aurora West Zone/GSN length weighted drill hole composites.
