TDG GOLD CORP. REPORTS NEAR SURFACE PORPHYRY-STYLE COPPER-GOLD AT BAKER AND EXTENDS
HIGH GRADE B-VEIN, TOODOGGONE
White Rock, British Columbia, July 25, 2023 - TDG Gold Corp. (TSXV: TDG) (the “Company” or “TDG”) is
pleased to announce that the first hole from its relogging, resampling and assaying of historical core
appears to support the concept that the Baker (Figure 1) area of its Toodoggone properties may represent
a bulk-tonnage, porphyry-style copper-gold target that was later over- printed by high grade epithermal
gold mineralization. Historical hole BK87-16 was drilled in 1987 targeting high-grade gold-silver (“Au-Ag”)
mineralization associated with the Baker B-Vein (Figure 2) that was the target of mining at that time, with
ore milled at the nearby Baker mill. As a result, it was only sporadically sampled based on that target
model. TDG’s relogging and resampling of the entire hole has not only confirmed the historical high-grade
Au-Ag epithermal-style mineralization, extending this style of mineralization to depth and along strike of
the historical mining, but has also identified porphyry-style copper-gold (“Cu-Au”) veining, alteration and
mineralization comprised of bornite, chalcopyrite and molybdenite over more than 60 metres of core
length starting from near surface and ending in mineralization.
The intercept comprises 0.1 % copper (“Cu”) and 0.7 grams per tonne (“g/t”) Gold (“Au”) over a 60.5 m
intercept from 62.6 m down hole, including 0.27 % Cu and 2.1 g/t Au over 17.9 m from 98.2 m down hole
(Table 1).
Steven Kramar, TDG’s VP Exploration, commented: “We are not aware of any detailed logging and
sampling that has been focused on the porphyry -style copper-gold potential at Baker. These first assay
results from resampling a single diamond drillhole completed at the Baker B-Vein in 1987, integrated with
geophysical and geochemical data, validates the copper -gold potential at Baker . The drillhole was o nly
drilled to a depth of 123 metres, which is deeper than most of the historical drill testing and ends in copper-
gold mineralization.”

TDG’s 2023 Exploration Program at Baker
TDG is approaching Baker1 as a “back to basics” project with p otential to host a bulk tonnage porphyry -
style copper-gold deposit that is most likely located deeper than historically drilled holes. By relogging,
resampling and assaying the historical core with a focus on identifying paragenesis of mineralized veins,
TDG aims to use the new information to help identify vectors to potential porphyry targets for drill testing
in 2024. In parallel with the historical core program, TDG has begun an extensive and intensive stream
sediment sampling program across the Baker footprint focused on the potential for a porphyry target.
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 342
drillholes across the 1 5 square kilometre (“sq.km”) Baker project . The Baker historical core inventory is
located at the Baker camp and mill site. So far, TDG has identified 91 complete/nearly complete drillholes
for relogging, of which 41 are restacked and ready for logging, 8 have been fully relogged; and 3 have
been submitted for assaying.
During the historical drilling that took place between 1974-2006, only ~15% of the drill cores are estimated
to have been assayed 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 8 drillholes logged so far. TDG has also
noted a significant reduction in BK87-16 for the grades for gold and silver grades in resampled core
compared to historical recorded results for the same hole – see Results Comparison section below.
Historical Baker Mine
Baker is a former producing, high -grade Au-Ag mine that operated intermittently from 1981-1997.
Exploration efforts continued sporadically through to 2010. The focus of exploration historically was to
identify high-grade epithermal Au-Ag veins for potential extraction and processing through the Baker mill,
which originally included a copper circuit before being redesigned to process Shasta ore through to its
closure in 2012. Baker is located adjacent to TDG’s Shasta resource stage, epithermal Au -Ag project and
existing infrastructure consisting of mining road, historical mill and tailings storage facilities.
Baker B-Vein
The Baker B -Vein was the second zone where small -scale extraction took place at Baker 1. Production
records from mining at Baker noted approximately 17,500 tons of ore extracted from the B-Vein by Sable
Resources at a grade of 0.9 ounce per ton (“opt”) Au, 5 opt Ag and 1 % Cu 2. Over 8,400 m of historical
diamond drilling2,3 is recorded at the B -Vein in 86 drillholes. Most historical assaying took place at the
Baker mill laboratory2,3. A very low percentage (<5 %) of historical core from the B-Vein appears to have
been assayed for copper, based on available assay certificates5.
The presence of chalcopyrite/bornite/molybdenite has been identified in multiple core samples targeting
the B-Vein by TDG. This is the most common sulphide assemblage of primary Cu -Au porphyry deposits.
Past academic studies support Baker mineralization having a component of magmatic water in addition
to meteoric water in the hydrothermal fluid. The magmatic component of the h ydrothermal fluid is
suggestive of the influence of a porphyry system at depth.
By systematically relogging the historical core, including drillholes where extraction is known to have
taken place, followed by resampling where appropriate, TDG is aiming to assemble the first
comprehensive copper-focused drill database for Baker and to select drill-ready targets for 2024.
Chris Dail, a technical consultant leading TDG’s regional program, commented: “There were some truly
spectacular gold-silver intercepts reported in the historical drill logs across Baker. The widespread nature
of these intercepts, albeit with sporadic assaying, with a copper signature, hints at a much bigger porphyry

system nearby. The only way forward is back to basics but we’re fortunate to have access to the inventory
of historical core that we can methodically work through.”
Alteration/Mineralization
The core exhibited multiple generations of veining (Figure 3) associated with bornite, chalcopyrite and
molybdenite cross-cutting pervasive pyrite + sericite (phyllic) alteration in the rock matrix (Figure 4). The
phyllic alteration and sporadic potassic alteration cross-cut earlier epidote + magnetite alteration and
veining. These porphyry assemblages, represented by the 62.6 m mineralized intercept (Table 1, 0.91 g.t
AuEq4 / 0.74 % CuEq 4), are crosscut by high -grade intermediate sulphidation epithermal veins ,
represented by the 4.8 m intercept (Table 1, 8.11 g/t AuEq4 / 6.55 CuEq4). This is suggestive that an earlier
porphyry event was overprinted by a later epithermal system and historical efforts focused on the
epithermal potential whereas the porphyry potential appears to have been underappreciated.
Alteration was generally pervasive throughout the entire drillhole, with alteration and mineralization
increasing with depth. A noticeable structural break suggests a fault-bounded mineralized bottom half (>
60 m, downhole) of the drillhole where mineralization and alteration increase abruptly, and the drillhole
ends in moderate Au+Cu mineralization: 3.1 m of 0.07 % Cu, 0.21 g/t Au and 6 g/t Ag from 120.0-123.1 m
depth (0.32 g/t AuEq4 or 0.26 % CuEq4).

content using US$ o f $1,800/Oz Gold (Au), $22.50/Oz Silver (Ag) and $3.25/lb Copper ( Cu) and have not been adjusted to reflect

Equivalent and Copper Equivalent is used for illustrative purposes to express the combined value of Au, Ag and Cu as a percentage 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

Historically selected sample intervals may differ from assayed intervals of resampled core for logistical
and scientific reasons. The historically2,3 published results indicate significantly higher grades for Au (+28
%) and Ag (+40 %), and increased Cu grades (+11 %) as compared to the assaying of resampled core by
TDG. Differences could be due to a combination of historical effects including : sample selection
methodology, a nugget effect, and/or 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 North Vancouver, B.C. The historic drill cores
were stored by previous operators in a core storage yard near the Baker Mill. TDG staff recovered and
inventoried the historic core and compared and validated the recovered core against historic 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 drill core 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. Samples were prepared and analyzed following procedures Au-GRA21 for Au and
ME-ICP61 for trace elements. Overlimit concentrations of precious or base metals were analyzed (where
applicable) by Au -GRA22, Ag-GRA22, and Cu-OG21 for A u, 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,
blanks, and duplicates. An additional QAQC program was administered by TDG through the verification of
lab results via use of certified reference materials (“CRMs”) and blank (unmineralized) samples that were
blindly inserted into the sample batch. If a QAQC sample returns an unacceptable 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.

BK87-16 utilized NQ size for drill core. During the resampling process, the entire remaining drill core 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 DGPS in due course. Table 3 presents the drillhole particulars.

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 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 Drill Core Sampling & Assay Methodology : Historical core was geologically logged with lithologies identified and notable
geological features recorded. Historical core 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 comm ercial
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 calculations reflect total gross metal
content using US$ of $1,800/Oz Gold (Au), $22.50/Oz Silver (Ag) and $3.25/lb Copper (lb) and have not been adjusted to reflect
metallurgical recoveries. The above metal prices are approximately in line with the LME 3 -year trailing average metal price . Gold
Equivalent and Copper Equivalent is used for illustrative purposes to express the combined value of Au, Ag and Cu as a percentage 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.
5Unassayed Historical Drill Core: Historical drill core intersections, lengths or intervals referenced for re-assay or geological analysis may
not be available or suitable for sampling. Historical drill cores were inherited with the project and TDG provides no guarantees or
warranties that these drill cores 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 pro vides no warranties/guarantees that these historical un-
assayed drill cores host precious or base metal mineralization.
