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 – September 23, 2026 – 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.
Key results
• Baker–North Quartz: Gold and copper soil anomalies extend across several kilometres, while
preliminary modelling identifies separate induced polarization (“IP”) chargeability responses
distributed over an approximately 3.5 -kilometre span . These responses extend the area of
interest beyond the historical Baker high- grade gold -copper-silver mine workings and are not
interpreted to be a single continuous body, rather a complex of anomalies.
• Black Gossan: Preliminary modelling outlines a pronounced chargeability response with an
approximately 2.1-kilometre horizontal extent in section , associated with relatively low
resistivity, mapped alteration, soil geochemistry anomalies and magnetic contrasts.
• Price–Trident: Copper and gold soil enrichment, intrusive geology and a local magnetic feature
are associated with separate shallow and deeper chargeability responses across an
approximately 1.45-kilometre span.
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.”

A Corridor-Scale Strategy for Target Prioritization
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.
The principal exploration model is a corridor containing multiple intrusive -related hydrothermal
centres and associated epithermal systems. Of particular interest are telescoped environments,
where younger, shallower gold -rich mineralization may overprint earlier copper –gold porphyry
system(s).
The regional alignment of Aurora West, Shasta, Newberry, Price–Trident, Black Gossan, Baker–North
Quartz, and emerging targets farther north, defines a northwest-trending corridor with demonstrated
copper, gold and silver endowment. TDG’s integrated approach is intended to identify the strongest
near-surface opportunities and determine where multiple datasets support priority targets for
potential drill testing.
Soil Survey: Expanding Target Footprints
3,455 soil samples have been collected against an expanded plan of approximately 5,000
samples.
Phase I established regional reconnaissance coverage using 200 -by-200-metre and 200 -by-400-
metre sampling. Its purpose was to evaluate previously underexplored ground and identify new gold,
copper and pathfinder-element anomalies.
Phases II and III are providing detailed follow-up through predominantly 100-by-100-metre sampling,
locally with 50 -by-50-metre infill, in areas of interest. This closer -spaced coverage is designed to
refine anomaly boundaries, establish internal trends and identify the best locations for potential drill
testing.
Results received to date demonstrate that the geochemical footprints around several historical
occurrences are substantially broader than the individual showings that originally defined them.
Around Baker –North Quartz, anomalous gold and copper values are distributed across several
kilometres, extending the target well beyond the former Baker mine workings. Additional anomalous
areas have been identified through Price–Trident and northward along the corridor.
The soil data also identify new areas of gold and copper enrichment where no established target had
previously been defined (Figure 1) . These anomalies may represent surface expressions of
previously unrecognized mineralizing centres and allow TDG to evaluate the continuity of prospective
trends between known occurrences.
North of Trident, emerging soil anomalies extend the investigation toward the property boundary and
occur along the broader regional trend that continues toward Finlay Minerals’ (Freeport JV)

neighbouring “Gold” target. The neighbouring occurrence is referenced for regional geological
context only and is not necessarily indicative of mineralization on TDG’s property.
Geophysics: Investigating the Systems Below Surface
The 2026 geophysical program comprises approximately 55 line- kilometres of DCIP across eight
regional lines, with approximately 48 line- kilometres completed and one seven -kilometre line
remaining. The lines provide consistent, large -area coverage across the corridor, extending beyond
individual historical showings.
The program also includes ground -based passive magnetotelluric data, acquired to provide
complementary information on subsurface resistivity and the possible deeper architecture of the
mineralizing systems.
Integrated IP , resistivity and magnetotelluric data help evaluate potential sulphide -bearing rocks,
alteration, intrusive contacts and structures below surface. Preliminary modelling shows
associations with known occurrences and soil anomalies, allowing TDG to assess target scale and
prioritize areas supported by multiple independent datasets for potential drilling.
Target Findings
Baker–North Quartz: Expanded Footprint and Multiple Responses
The 2026 soil survey has expanded the gold and copper footprint around Baker –North Quartz to
several kilometres, well beyond the area historically explored around the Baker veins.
Preliminary DCIP inversion modelling identifies several separate chargeability responses across an
approximately 3.5 -kilometre span . These responses occur within a broader magnetic low
containing distinct internal magnetic features. They are not presently interpreted as one continuous
body but collectively demonstrate that the broader Baker –North Quartz area contains multiple
subsurface targets.
Baker is historically recognized as an epithermal gold –silver system with some porphyry affinities .
Previous drilling also demonstrated that mineralization extends beyond the high-grade veins. In 2023,
resampling of historical drill hole BK86 -10 returned 100.3 metres grading 1.07 grams per tonne
(“g/t”) gold, 0.10% copper and 4 g/t silver, including 37.4 metres grading 2.69 g/t gold and 0.19%
copper. Reported drill intervals are core lengths. Estimated true widths are 40 –60% of core length,
and historical core recovery is unknown. Additional information is available in TDG’s August 15, 2023
news release.
The expanded soil footprint, multiple IP responses and historical broad mineralized drill
intersections support evaluating Baker as a potentially larger hydrothermal system than indicated
previously.
Black Gossan: Kilometre-Scale Subsurface Response
Preliminary DCIP modelling identifies a pronounced chargeability response over an approximately
2.1-kilometre horizontal extent in section, accompanied by relatively low resistivity.

The response is substantially larger than the historical surface occurrence and is associated with
mapped alteration, anomalous soil geochemistry and magnetic contrasts. This combination
supports the interpretation of a potentially extensive sulphide-bearing hydrothermal system.
Further interpretation will focus on identifying the most prospective near -surface portion of the
response and distinguishing possible copper -bearing mineralization from a predominantly pyritic
alteration envelope. The extent of the geophysical response do es not necessarily represent a
mineralized or economic deposit footprint.
Price–Trident: Coincident Geochemical and Geophysical Target
The Price–Trident area contains copper and gold soil enrichment associated with intrusive geology
and a local magnetic feature. Preliminary modelling identifies separate shallow and deeper
chargeability responses across an approximately 1.45-kilometre span in the broader Price–Trident
sector.
The spatial relationship between the geochemistry, geology, magnetics and DCIP supports
evaluating Price–Trident as an intrusive-related hydrothermal system with potential for near-surface
copper–gold mineralization and associated epithermal mineralization.
The 2026 program has improved the definition of this target and provides a framework for locating the
strongest convergence of surface geochemistry and subsurface geophysics.
Greater Shasta–Newberry (GSN): Evaluating Growth and Nearby Targets
In the GSN area, detailed soil sampling is improving coverage around the existing Shasta epithermal
gold–silver mineral resource. The objective is to assess whether geochemical patterns, geological
structures and geophysical responses identify opportunities to extend mineralization beyond the
areas tested by historical and recent drilling.
Newberry remains an undrilled target situated along the same broader corridor as Shasta. Its multi-
element soil signature, structural position and magnetic character support continued evaluation as
a potential epithermal or intrusive-related target.
The integrated regional program provides, for the first time, a common dataset with which to assess
Shasta, Newberry and the intervening ground. This is intended to help determine whether
opportunities exist for resource growth at Shasta, nearby satellite mineralization or additional
mineralizing centres along trend.
Emerging Regional Targets
Reconnaissance soil sampling has identified additional anomalous areas away from the principal
historical showings. Follow-up work is evaluating these new targets based on their gold, copper and
pathfinder-element signatures, geological setting, magnetic c haracter and proximity to DCIP
responses.
These areas remain at an early stage, but they expand the Company’s target inventory and
demonstrate the benefit of assessing the entire corridor rather than limiting exploration to known
occurrences.

Next Steps: Target Ranking and Selection
Remaining soil assays, infill sampling, geological mapping and final DCIP , resistivity, magnetic and
magnetotelluric interpretations will be combined into a corridor-wide target-ranking framework.
Targets will be evaluated according to the strength, size and coherence of their geochemical
response; interpreted depth and geometry of geophysical features; geological and structural setting;
potential for near -surface mineralization; and the degree of a greement between independent
datasets.
The objective is to develop a ranked portfolio from which to select targets for potential drill testing of:
• extensions to known mineralized systems, including Baker and Shasta;
• potential near -surface, gold -rich telescoped porphyry systems, using Aurora as a regional
exploration model;
• near-surface, bulk-tonnage epithermal gold–silver opportunities; and
• potential new mineralizing centres identified through regional exploration.
TDG expects the completed program to provide the technical basis for selecting and sequencing
follow-up ahead of the 2027 field season, with priority given to targets supported by the strongest
combination of geological, geochemical and geophysical evidence.
Soil Sampling, Analytical Methods and Quality Assurance/Quality Control
Soil samples were collected predominantly from the B -horizon by trained field personnel using
standardized procedures. Samples followed documented chain of custody between collection,
processing and delivery to the analytical laboratory.
Samples were submitted to ALS Canada Ltd. (“ALS”) in Kamloops, British Columbia, for preparation
and to ALS in Vancouver, British Columbia, for analysis.
Analysis utilized method AuME-ST43, comprising aqua-regia extraction of a 25-gram aliquot followed
by inductively coupled plasma mass spectrometry and inductively coupled plasma atomic emission
spectroscopy for gold and multiple elements. The method provides a lower gold detection limit of 0.1
parts per billion. Aqua regia provides a partial extraction, and reported results may not represent the
total concentration of certain elements in the sample.
Quality assurance and quality control (“QA/QC”) are maintained internally by ALS through the use of
certified reference materials, blanks and duplicates. TDG maintains an additional QA/QC program
through the blind insertion of certified reference materials , blank samples and duplicate samples
into the analytical sequence. If a QA/QC sample returns a result outside acceptable limits, an
investigation is initiated and, where warranted, samples associated with the affected batch are
reanalyzed.
