TDG GOLD CORP. REPORTS MORE BROAD, NEAR SURFACE PORPHYRY-STYLE COPPER-GOLD AT BAKER
White Rock, British Columbia, September 0 6, 2023 - TDG Gold Corp. (TSXV: TDG) (the “Company” or
“TDG”) is pleased to announce assay results from resampling of four additional historical drillholes which
further support the concept that the Baker Complex1 area of its Toodoggone properties may represent a
bulk-tonnage, porphyry -style copper -gold target1. The porphyry -style mineralization was later
overprinted by a high-grade epithermal gold-silver (“Au-Ag”) system. Historical drilling at the Baker B-Vein
targeted high-grade Au-Ag mineralization and, a s a result, drillholes were historically only s electively
sampled based on the epithermal Au -Ag model, neglecting broader mineralized zo nes, and were not
assayed for base metals5.
TDG’s relogging and resampling program at the Baker B -Vein (i) confirmed the historical high-grade Au-
Ag epithermal-style mineralization, (ii) extended this style of mineralization to depth and, in addition, (iii)
identified porphyry -style copper-gold (“ Cu-Au”) veining, alteration and sulphide mineralization. The
porphyry-style mineralization is comprised of pyrite, chalcopyrite , molybdenite and minor bornite
extending up to 1 26.8 metres (”m”) of core length , starting from near surface and ending in
mineralization in all four recently resampled historical drillholes (Table 1).
A cross section for the Baker B-Vein exploration area1 (Figure 1) and a plan map (Figure 2), demonstrate
the continuity of Au-Ag mineralization and the continuity of the widespread porphyry-style alteration, and
suggests both styles of mineralization remain open along strike and at depth.

4Gold Equivalent (AuEq) & Copper Equivalent (CuEq): Gold Equivalent and Copper Equivalent are used for illustrative purposes to express
the combined value of Au, Ag and Cu as an equivalent of Au or Cu on an in- situ basis. Calculations are uncut, and actual prices and
recoveries (following metallurgical tes t work) may differ from these assumptions which would change the equivalent value. Price
assumptions (approximately in line with the LME 3-year trailing average metal prices) of US$ of $1,800/Oz Au, $22.50/Oz Ag and $3.25/lb
Cu (lb) are used with assumed metallurgical recoveries of 94.8 %, 77.2 % and 90.0 % recovery for Au, Ag and Cu, respectively. The resulting
formulas are: AuEq(g/t) = ((Au_g/t × Au price per g/t × Au recovery)+(Cu_wt.% × Cu 1% price per tonne × Cu recovery)+(Ag_g/t × Ag price
per g/t × Ag recovery)) / (Au price per g/t). CuEq(wt.%) = ((Cu_wt.% × Cu 1% price per tonne × Cu recovery)+(Au_g/t × Au price per g/t ×
Au recovery)+(Ag_g/t × Ag price per g/t × Ag recovery)) / (Cu price 1 % per tonne).

Steven Kramar, TDG’s VP Exploration, commented: “ We’ve now published assay results from seven
historical drillholes at the Baker B -Vein located outside the footprint of the small -scale gold-focused
extraction that took place in the 19 90s. All seven resampled holes have demonstrated near surface
porphyry-style mineralization extending over broad intervals , including higher grade epithermal gold-
silver-copper veining as an overprint and, most importantly, ending in previously unrecognized copper-
gold mineralization. The B-Vein high-grade gold system also remains open along strike and at depth.
Our historical core relogging program has recently been extended to include drillholes across the Baker
Complex (which covers ~15 sq.km), with nine historically defined exploration target areas. In parallel, our
lithic drainage sediment sampling program is now complete and covers the entire Baker Complex and the
adjacent Greater Shasta-Newberry project (the latter includes our mineral resource stage Shasta project).
This appears to be the most comprehensive sampling program ever completed at the Baker Complex with
a copper -gold focus. We look forward to publishing more results in the coming weeks from these
programs.”

TDG’s 2023 Exploration Program at Baker
As reported in our July 25, 2023 & August 15, 2023 news releases, TDG is approaching the Baker Complex1
as a “back to basics” project with potential to host a bulk tonnage porphyry-style copper-gold deposit that
is most likely located below historically drilled holes 2. TDG has a relogging, resampling and assaying
program underway that aims to use the new information to help identify vectors to potential porphyry
targets for drill testing in 2024.
TDG has also completed an extensive and intensive lithic drainage sediment sampling (“LDS”) program
across the Baker Complex 1 and Greater Shasta- Newberry1 footprint focused on the potential for a
porphyry target. Results are anticipated by mid-October 2023.
TDG’s historical core relogging , resampling and assaying program is low cost and aim s to recover and
resample as much as possible of the ~30,000 m of diamond drilling known to have been completed in
approximately 350 drillholes across the 1 5 square kilometre (“sq.km”) Baker Complex 1. The Baker
historical core inventory is located at the Baker camp and mill site. So far, TDG has identified
approximately 100 complete/nearly complete drillholes for relogging, of which approximately 60 are
restacked and ready for relogging, 10 have been fully relogged, and 10 have been submitted for assaying
and results have been received from 7 (reported herein, July 25, 2023 and August 15, 2023).

During the historical drilling that took place between 1974-2006, only ~15 % of the drillcore length is
estimated to have been assayed 3 for gold-silver5 and virtually none for any other elements , including
copper5. TDG has noted the presence of porphyry -style veining and alteration and the occurrence of
bornite (Cu5FeS4), chalcopyrite (CuFeS2) and molybdenite (MoS2) throughout the drillholes relogged.
By systematically relogging the historical core, including drillholes where mining is known to have taken
place, followed by resampling5 where appropriate, TDG is aiming to assemble the first comprehensive
copper-focused drill database for the Baker Complex1 and to select drill-ready targets for 2024.
Alteration/Mineralization
The geology of Baker B-Vein area can be summarized as a succession of dacite, andesite and associated
volcanic tuffs and epiclastic rocks with pervasive widespread quartz-sericite-pyrite (“QSP”) alteration. This
package of rocks is cross-cut by multiple intrusive phases and multi-generational stockwork-style quartz,
quartz-potassium feldspar and epidote veins hosting pyrite, magnetite, chalcopyrite and occasionally
sphalerite, galena and bornite within veins or on vein selvages. All four drillholes reported in th is news
release ended in Cu-Au mineralization, with anomalous base metals.
The B-vein has a strike length of at least 300 m (the extent of the current drilling), has a vertical extent of
over 100 m and lies within a mineralized zone that is approximately 60 m wide. The current extent of
drilling, and current re -interpretation of the B -Vein suggest that the high-grade Au-Ag mineralization is
open along strike to the west-southwest (trending towards the A-Vein) and to the east-northeast, and at
depth, in addition to the widespread Cu -Au porphyry potential surrounding the historical high -grade
mineralized target zone.
All B-Vein relogged and modern assayed drillholes continue to support the concept that the Baker B-Vein
is a high-grade Au-Ag mineralized core surrounded by a lower grade halo of Cu-Au mineralization and the
Cu mineralization in the epithermal veining is likely a function of metal scavenging by hydrothermal fluids
from a larger porphyry system at depth.

****Calculated composites may not sum due to rounding errors.
*****Historically selected sample intervals may differ from assayed intervals of resampled core for logistical and scientific reasons.
Historical Au composite interval data2,3 were compared with modern composite results to investigate data
repeatability and reliability. Using the same composite intervals (where available) the first seven B-Vein
drillhole composite inte rvals reported an correlation coefficient (R) of 0.79, illustrating satisfactory

correlation of Au and providing reasonable confidence in historical results. Specifically, BK86-14 reported
a 25 % reduction in Au grade (comparing one composite interval), BK86-17 reported a > 40 % increase in
Au grades (comparing two composite intervals), BK86-22 reported a 355 % increase in Au grades
(comparing one composite interval) and BK 87-07 had no near comparable composite result . These
differences could be due to a combination of factors including: (i) nugget effect, (ii) sample selection
methodology and/or, (iii) laboratory methodology particularly for assay results generated by the historical
Baker mill laboratory2,3.
QA/QC
Samples for the Baker 2023 core relogging program were handled via rigorous chain of custody, between
collection, processing, and delivery to the ALS laboratory in Kamloops or North Vancouver, B.C. The
historical drillcores were stored by previous operators in a core storage yard near the Baker Mill. TDG staff
recovered and inventoried th e historical core and compared and validated the recovered core against
historical core logs, box labels and core blocks . The core was subsequently relogged, photographed and
sampled at TDG’s Baker Mine site and processed by geologists and technicians . Quality assurance and
control (“QAQC”) materials were inserted into the sampling sequence during geological sample selection.
The drillcore was selected for sampling and placed in zip-tied polyurethane bags, then in security-sealed
rice bags before being delivered directly from the Baker Mine site to Bandstra Transportation Systems in
Prince George, B.C., and transported to ALS’ preparation facility in Kamloops, B.C., and ultimately to the
ALS laboratory in North Vancouver, B.C (or remained for analysis in Kamloops, B.C.) . Samples were
prepared and analyzed following procedures Au-GRA21 for Au and ME-MS61 for trace elements. Overlimit
concentrations of precious or base metals were analyzed (where applicable) by Au-GRA22, Ag-GRA22, and
Cu-OG21 for Au, Ag and Cu respectively. Information about methodology can be found on the ALS Global
website, in the analytical guide (here).
QAQC is maintained internally at the lab through rigorous use of internal certified reference materials
(“CRMs”), blanks, and duplicates. An additional QAQC program was administered by TDG through the
verification of lab results via use of CRMs and blank (unmineralized) samples that were blindly inserted
into the sample batch. If a QAQC sample returns an unacceptabl e value an investigation into the results
is triggered and when deemed necessary, the samples that were tested in the batch with the failed QAQC
sample are re-tested.
Drillholes in Table 3 utilized NQ size for drillcore. During the resampling process , the entire remaining
drillcore was consumed (either the second half of the remaining material, or the entire remaining
unsampled material) due to the small diameter of the core. The historical collar location was verified by
handheld GPS and will be sited utilizing a more precise Real Time Kinematics (“RTK”) measurement in due
course. Table 3 presents the drillhole particulars for drillholes in this news release.

The geologically related technical content of this new release has been reviewed and approved by Steven
Kramar, P.Geo., Vice President, Exploration for TDG and a Qualified Person, as defined under National
Instrument 43-101.
1Mineral Exploration/Exploration Target Area(s): TDG is a mineral exploration focused company and the Company’s Projects are in the
mineral exploration stage only. The degree of risk increases substantially where an issuer’s properties are in the mineral ex ploration
stage as opposed to the development or operational stage. Exploration targets and/or Exploration zones and/or Exploration areas are
speculative and there is no certainty that any future work or evaluation will lead to the definition of a mineral resource.
2Historical Data: This news release includes historical information that has been reviewed by TDG’s qualified person (QP). TDG’s review of
the historical records and information reasonably substantiate the validity of the information presented in this news release; however,
TDG cannot directly verify the accuracy of the historical data, including (but not limited to) the procedures used for sample collection and
analysis. Therefore, any conclusions or interpretations borne from use of this data should be considered too speculative to suggest that
additional exploration will result in mineral resource delineation. TDG encourages readers to exercise appropriate caution when evaluating
these data and/or results.
3Historical Drillcore Sampling & Assay Methodology: Historical drillcore was geologically logged with lithologies identified and notable
geological features recorded. Historical drillcore was split in half (and in rare cases sawn in half) along sample intervals (lithology and
mineralization dependant) generally less than 3 m. Chemical analysis was performed dominantly for precious metal analysis (Au and Ag),
and infrequently for base metals (Pb, Zn, Cu), and rarely for major elements and trace elements. Historically, different commercial
laboratories were utilized in addition to an assay lab at Baker Mine Site. These lab facilities may or may not have had accreditation and in
all cases accreditation (if applicable) pre-dated current ISO standards. Over that period, a variety of digestion and assay methods were
used, including atomic absorption, fire assay atomic absorption, aqua regia atomic absorption and aqua regia ICP with varying detection
limits. Reference materials (if any) were inserted at the analytical level and thus were unblind to the facility processing the samples.
4Gold Equivalent (AuEq) & Copper Equivalent (CuEq): Gold Equivalent and Copper Equivalent are used for illustrative purposes to express
the combined value of Au, Ag and Cu as an equivalent of Au or Cu on an in- situ basis. Calculations are uncut, and actual prices and
recoveries (following metallurgical test work) may differ from these assumptions which would change the equivalent value. Price
assumptions (approximately in line with the LME 3-year trailing average metal prices) of US$ of $1,800/Oz Au, $22.50/Oz Ag and $3.25/lb
Cu (lb) are used with assumed metallurgical recoveries of 94.8 %, 77.2 % and 90.0 % recovery for Au, Ag and Cu, respectively. The resulting
formulas are: AuEq(g/t) = ((Au_g/t × Au price per g/t × Au recovery)+(Cu_wt.% × Cu 1% price per tonne × Cu recovery)+(Ag_g/t × Ag price
per g/t × Ag recovery)) / (Au price per g/t). CuEq(wt.%) = ((Cu_wt.% × Cu 1% price per tonne × Cu recovery)+(Au_g/t × Au price per g/t ×
Au recovery)+(Ag_g/t × Ag price per g/t × Ag recovery)) / (Cu price 1 % per tonne).
5Unassayed Historical Drillcore: Historical drillcore intersections, lengths or intervals referenced for assay or geological analysis may not
be available or suitable for sampling. Historical drillcores were inherited with the project and TDG provides no guarantees or warranties
that these drillcores are part of the historical inventory, are available and/or have not degraded to a state that would render them wholly
unusable for the purposes of scientific investigation. TDG provides no warranties/guarantees that these historical unassayed drillcores
host precious or base metal mineralization.
