TDG OUTLINES ~12 KM STRUCTURAL CORRIDOR OF COPPER-GOLD PORPHYRY TARGETS, TOODOGGONE
White Rock, British Columbia, March 03, 2025 - TDG Gold Corp. (TSXV: TDG) (the “Company” or “TDG”)
is pleased to report identification of a ~ 12 kilometre (“km”) structural corridor of copper -gold porphyry
targets within its 100% owned Greater Shasta -Newberry and Baker Complex mineral claims. Re -
interpreted geophysical data, supported by sediment, rock and soil sampling and geologic information, is
suggestive of a series of potential copper- gold (“Cu-Au”) porphyry systems covering ~ 12 kilometres of
strike that merit systematic exploration (Figure 1) . Evaluation of these targets will be part of TDG’s
planned and fully funded 2025 exploration program.
There will be in a live webinar at 10:00 am pacific time on March 12, 2025, to present the information

Greater Shasta-Newberry & Baker Complex
TDG’s Greater Shasta-Newberry project is located adjacent to the recently announced AuRORA1 gold-rich
copper porphyry discovery by Freeport McMoRan Inc. and Amarc Resources Limited (“Freeport-Amarc”)
(news release Jan 17, 2025) . Greater Shasta- Newberry and the Baker Complex cover ~60 sq.km and
encompass TDG’s mineral resource 2 at the former producing gold- silver Shasta mine (news release Jan
08, 2025) and the former high-grade gold-silver-copper underground mine at Baker. The Greater Shasta-
Newberry and Baker Complex areas share a number of similarities3 with the AuRORA1 deposit.

Targeting Techniques
Successful targeting for porphyry -style mineralization at AuRORA 1 appears to be based on identifying
major structural and geological controls and applying geophysical techniques that characterize (i)
magnetite-rich portions of mineralized intrusive systems, (ii) conductive zones associated with networks
of sulphides that could be indicative of mineralized areas with high vein densities, and (iii) high
chargeability anomalies. Applying this approac h to TDG’s properties using the currently available
geophysics has identified multiple , discrete, coincident high -magnetic and low -resistivity anomalies

(Figure 1). One of the key tools used in defining AuRORA1 appears to have been Induced Polarization (“IP)
geophysics, which has never been completed on these newly identified targets and will be an important
step to finalise drill placement on TDG’s high priority targets.
Technical Support
TDG is pleased to announce that it has retained Jeff Kyba , P.Geo, consulting geologist, to assist with its
exploration targeting in 2025. Jeff Kyba was co-author in defining the ‘Red Line’ in BC’s ‘Golden Triangle,’
NW British Columbia - a stratigraphic unconformity located within 2 km of nearly all major deposits in the
Stikine Terrane separating the Lower Hazelton (Jurassic) and Upper Stuhini (Triassic) Groups of rocks. The
Toodoggone District is also part of the Stikine Terrane and the analogue of the ‘Red Line’ in this area is
the unconformity between the Lower Hazelton (Jurassic) and Upper Takla (Triassic) Groups of rocks.
Steven Kramar, TDG’s VP Exploration, commented: “We have begun an iterative process to understand the
controls on the AuRORA 1 mineralization and how these might have implications for Greater Shasta -
Newberry, and potentially parts of a larger system extending over ~12km. The AuRORA1 discovery is in the
same regional corridor as our Trident target (news release Mar 07, 2024) and AuRORA1 has improved our
understanding of potential controls on mineralization in the area. We are looking forward to mobilizing at
the earliest opportunity, so we can begin the evaluation of this trend on TDG’s properties.
TDG is also pleased to welcome Jeff Kyba to the team. His work with the Kyba -Nelson ‘Red Line’ and
understanding geological conditions for favourable mineralization will be important as we explore across
our Toodoggone portfolio.”
Importance of the ‘Red Line’
The Kyba -Nelson ‘Red Line’ (201 4†) is a recognized structural and stratigraphic boundary in British
Columbia’s ‘Golden Triangle’ and Toodoggone District. This horizon marks a major geological unconformity
and structural weakness zone associated with significant porphyry and epithermal mineralization. Many
world-class deposits 1 (KSM, Red Chris, Brucejack, Kemess) and significant deposits/prospects1 (Baker,
Shasta, Lawyers, Pine, AuRORA) are located within 2 km of this exposed contact. Nearly the entirety of the
Baker Complex, Greater Shasta-Newberry and the intervening ground are all within 2 km of the historically
mapped ‘Red Line’ (Figure 2).

Geophysics
The Baker Complex and Greater Shasta -Newberry area exhibit multiple, coincident overlapping
geophysical signatures with similarities to the AuRORA 1 discovery and may be part of a larger porphyry
system. The geophysical inventory of studies completed (wholly or partially) currently includes:
• Magnetotellurics (“MT”) completed by Amarc -Freeport in 2023 which covers AuRORA 1 and a
portion of the boundary with Greater Shasta-Newberry
• Airborne magnetics, radiometric and Z -Tipper Electromagnetic (“ZTEM”) survey s by Sable
Resources Limited in 2017 across the Baker Complex, Greater Shasta-Newberry and AuRORA1
• Ground magnetics and Very Low Frequency Electromagnetics (“VLF”) surveys across Greater
Shasta completed by TDG in 2021 -2023 targeting shallow, epithermal gold -silver mineralization
(news release Oct 17, 2022)
• Historical limited ground magnetics and VLF surveys4 on one of the prospects
• Historical regional scale airborne magnetic and gravity surveys4 (focused on the Spur target)
To date, eight geophysical targets have been upgraded as high-priority areas of interest (Figure 1) that
demonstrate a ’magnetic high’ core (ie. magnetic anomaly) with an associated low resistivity (ZTEM) zone.
Ground geophysical data collected by TDG and airborne data by previous operators has now been sent to
a specialty geophysical firm for reprocessing and reinterpretation in the context of porphyry exploration
and the recent AuRORA 1 discovery. Additional targets across the Baker Complex are being re -evaluated
and may be added to the target list in due course.

Structure
A detailed structural review is underway utilizing historical geological studies and modern geophysical
(2D and 3D) datasets to better understand and define structural domains. In the Toodoggone District, two
structural fabrics potentially control porphyry and epithermal mineralization. Northwest parallel trending
faults, structures and lineaments appear to serve as a major control on the mines, deposits and prospects
from Kemess1 (in the southeast) through Pine 1, Shasta, Baker, Lawyers1, and Ranch1 (in the northwest).
These parallel northwest trending structures create ‘corridors’ of highly prospective areas for significant
mineralization (Figures 1 & 2).
A second fabric in the east -northeast direction appears to control clustering of areas of mineralization.
This is demonstrated at Kemess North 1, which also includes Nugget 1, Kemess Underground 1, Kemess
Offset1 and Kemess East1 deposits – all aligned along an east-northeast fabric. TDG’s past producing high-
grade Baker mine and associated unmined prospects are aligned along a prominent east-northeast trend
and past production had Cu enrichment . The Greater Shasta-Newberry and AuRORA1 area appears to
show similar controls (Figure 3 above).
