TDG GOLD CORP: SHASTA MINE COMPLEX GEOPHYSICS CONFIRMS NEW TARGETS
White Rock, British Columbia, October 17, 2022 - TDG Gold Corp - (TSXV: TDG) (the “Company” or
“TDG”) is pleased to announce the results and interpretation from the 100 line-kilometre (“km”) of high-
resolution ground-based magnetics and Very Low Frequency (“VLF”) survey work over the Shasta Mine
Complex.
The results suggest multiple, strong structural anomalies contained within a ~4 km x ~3 km area
surrounding the Shasta Deposit. The anomalies coalesce into clearly defined target zones including the
recently renamed “Cody Lee” and “Fisher” Zones (see Figure 1) which are both located to the east of the
Shasta Deposit; and the previously reported Newberry Prospect located ~1.5 km north of the Shasta
Deposit.
The results from the geophysics complement information from historical drilling in the Cody Lee and
Fisher Zones and soil sampling programs across the Shasta Mine Complex. For example, diamond drillhole
SH89-34 in the Cody Lee Zone which intercepted 17.1 metres (“m”) of 3.37 grams per tonne (“g/t”) gold
(“Au”) and 45 g/t silver (“Ag”) [3.94 g/t AuEq*] from 27.9 m depth; including 0.5 m of 91.5 g/t Au and 595
g/t Ag [98.94 g/t AuEq*] from 43.5 m depth.
This work represents TDG’s next step towards identifying priority drill targets for 2023 , as well as
determining the ultimate potential of the Shasta Mine Complex; and if i ndeed the Shasta Deposit is
actually part of a bigger related mineralized system.

RESULTS & INTERPRETATION
The technical work completed to date also incorporates historical data and information undertaken by
past operators including Newmont - which made the initial Shasta discovery in 1983 and identified
additional targets at the time. Epithermal deposits such as Shasta commonly occur in clusters.
The geological/geophysical results indicate consistent apparent offsets of the main north -northwest
feature by northeastern trending features that TDG interprets to potentially be faults and which have
typically hosted the higher-grade mineralisation drilled at Shasta. Of particular interest are new structures
identified at TDG’s Newberry target (located ~1.5 km to the north-northwest of the Shasta resource );
in the East Shasta area at the Fisher Zone and Cody Lee Zone Prospects; and also at Shasta South where
it appears the trend continues south of the Cayley-Rainier Zone (Figure 2). These structures differ from
the historical mapping interpretation of previous operators, including Newmont. This could lead to a new
interpretation of Shasta as a cluster of related epithermal lenses (“string of pearls”) covering an area ~4
km x 1 km and which may or may not have structurally connectivity and integrity.
Chris Dail, a consultant for TDG’s regional exploration program, commented, “ The ground- based
magnetics and VLF survey completed in September 2022 is the first step to try answer the question: how
big could the Shasta Mine Complex be? Work by Newmont in 1983 after the initial Shasta discovery, clearly
identified multiple opportunities that they recommended for follow up but were not . We also recently
completed a large soil sampling program over the Shasta Mine Complex to verify historical data, fill in gaps
and extend known anomalies . Combined with our recently completed geophysical surveys, we expect to
identify multiple new drill targets. It is rare to come across areas with such widespread mineralization of
the character observed in and around the Shasta Deposit as well as numerous poorly and untested
anomalies. The ability to develop a pipeline of drill targets bodes well for future discovery opportunities on
the project."
Steven Kramar, TDG’s Vice President, Exploration, commented, “ Chris Dail’s expertise and development
of our regional exploration program has given us the opportunity to execute two separate but parallel
technical teams: Chris’ team has reviewed historical data and collected and integrated new, high quality
information to develop our pipeline targets to a drill decision in 2023; meanwhile the Shasta resource team
continues to stay focused on testing and growing the known Shasta resource . This strategy has been
effective and successful, and we look forward to a busy 2023.”
PROGRAM SUMMARY
This year’s exploration program focused on generation of additional data to support future drill targeting
in the immediate area around the Shasta main Deposit, in the broader area of the Shasta Mine Complex.
Work included: i) detailed structural analysis of exposures in historical trenches, roads cuts, open pits and
outcrops east of the Shasta main Deposit that will be integrated with the oriented diamond drill core from
last year’s drill campaign and our ongoing program, ii) soil geochemistry and, iii) ground geophysical
surveys.
Emphasis during field work this season was on structural analysis focused on obtaining trends and cross
cutting relationships between different vein events. Observations of vein offsets by structural elements
will facilitate more detailed and reliable bloc k modeling of the Shasta main Deposit and provide
information for prediction of favourable trends and orientations.
TARGET GENERATION
In the late 1980s and early 1990s past operators completed large soil grids and VLF and VLF apparent
resistivity surveys using older Geonics EM16R VLF survey receiver instruments over portions of the
property and identified several targets based on the results. Many, in fact most, of the identified targets

were never drill tested. A few were and led to successful identification of mineralization which was the
partial focus of this year’s field exploration activities.
The Fisher Zone (formerly called O-Zone), located approximately 600 m southeast of the Shasta main
Deposit (Figure 1) consists of a broad ovoid area, approximately 350 m x 500 m across. The area has
limited outcrop and bedrock is situated beneath a thin veneer of glacial-derived sediment cover. A total
of seven shallow, small diameter, historical diamond drill core holes, totalling approximately 817 m, were
drilled be neath the shallow overburden to test EM16 R VLF geophysical anomalies and intersected
widespread disseminated gold and silver mineralization over 20 -30 metre (“m”) thick drilled intervals
(Table 1 ). Our VLF surveys from this season indicate th is mineralized prospect is along a series of
northeast-trending conductive zones defined by our Fraser filtered VLF. The area of anomalous precious
metals in bedrock and the VLF conductive zones are directly along strike and southeast of a large 350 -
metre x 500 metre gold-in-soils anomaly reported by past operators that is untested by drilling. The
footprint of this poorly drilled bedrock feature and the adjacent and contiguous surficial soil anomaly is
as large or larger than the current Shasta Mineral Resource footprint and may represent a large -scale
mineralized system.
The Cody Lee Zone (formerly called Christmas Creek Zone) is located approximately 500 m east-northeast
of the Shasta main Deposit (Figure 1). The zone consists of an ovoid area, approximately 400 m x 500 m
across which is immediately adjacent to the Shasta main Deposit access road. Outcrops along the roadcut
adjacent to the drilled area are intensely quartz and potassium feldspar altered , sulphidized, and are
heavily quartz-carbonate veined and brecciated. Outcrops are sparse away from the road cuts and the
adjacent area is covered with a veneer of transported alluvial gravels below the road and talus and glacial-
derived sediment cover above it. A total of seven shallow , small diameter, historical diamond drill core
holes, totalling approximately 697 m, were drilled above and below the road and beneath the shallow
overburden cover to test EM16R VLF geophysical anomalies and exposed alteration. These short holes all
intersected widespread alteration and cut variable intervals ranging from a few m up to 2 0 m of
disseminated and vein hosted gold and silver mineralization (Table 1) suggesting the presence of a large
scale mineralized system.

*Gold equivalent (AuEq) is used for illustrative purposes, to express the combined value of Au and Ag as a percentage of Au. Calculations are uncut and no
allowances have been made to accommodate potential recovery losses that would occur in a mining scenario. AuEq is calculated using 80:1 silver to gold ratio.
Composite results were built using a 0.1 g/t AuEq cut -off, although there are intervals within the composites below 0.1g/t AuEq.
** Intervals are core-length weighted. True width is estimated unknown.
***Calculated composites are truncated to significant 2 digits for Au/AuEq and the nearest whole number for Ag.
SHASTA EAST
Although outcrop is poor in the are a surrounding the Shasta main Deposit, exposures are present and
detailed analysis of structural elements in these exposures has proved to be valuable guides to trends not
previously recognized by past operators and which may control vein system development. A large east-
northeast tren ding soil anomaly lies east of the Shasta main Deposit (“Shasta East”). R econnaissance
mapping and prospecting located the projected extension of the zone in outcrops to the west of the Shasta
East historical soil anomaly, directly along strike and adjacent to the Shasta main Deposit. The intersection
of this structure and the primary north -northwest trending JM Zone and north -south trending Shasta
Zones may control higher grade mineraliz ation within the main Shasta main Deposit. Figures 3a and 3b

porphyry and a blow up of the inset to illustrate the style of alteration.

SOIL GEOCHEMICAL SURVEYS
Approximately 900 conventional B-horizon soils were collected in a series of grids east and west of the
main Shasta main Deposit. Sparse, widely spaced historical reconnaissance style drilling in the 1980s and
1990s in these areas intersected scattered but significant intervals of disseminated sulphides, potassium
feldspar alteration and epithermal veining. The widely spaced, shallow small diameter drilling was focused
on probing for high grade veins suitable for underground mining operations which were the targets at the
time. The 2022 program was designed to further advance these prospects to a drill stage.
GEOPHYSICAL SURVEYS
The geophysical surveys were completed August and September 2022. GEM systems GSM -19WMV
magnetometers were used for the magnetics and VLF surveys. The surveys consisted of collection of
magnetic readings, where magnetic field readings are measured once per second, and VLF readings, where
readings are measured ever y 20 m (nominal). The total distance surveyed on the Shasta and Newberry
grids is approximately 108 line -kilometres. Lines were spaced approximately 100 m apart with
measurements taken on average on 20 -metre centres along east -west oriented grid lines with periodic
north-south oriented tie lines.
The geophysical data was post -processed using conventional data reduction techniques, filtered and
gridded to produce a series of electronic deliverables. The surveys were of high quality and suitable for use
for the purposes intended. The magnetic data illustrates several key elements in the local area around the
Shasta main Deposit where outcropping bedrock exposures are sparse.
Five high priority, new prospects have also been identified which TDG believes merit follow-up exploration
work to generate drill targets (see Figure 2).
• Location A. Prominent north-northwest trending magnetic high correlates directly with a several
hundred met re wide x several metre long gold -in-soils and alteration zone at the Newberry
Prospect which was identified by Newmont in their work in the 1980s. The magnetic high extends
along strike to the south-southeast for another 800 m, but Newmont soil surveys did not cover this
area. The alteration zone at Newberry remains open to the south, beneath a veneer of talus and is
a compelling target to extend the Newberry anomaly.
• Location B. Situated in an area completed covered with glacial overburden, a sharp magnetic
north-northwest trending magnetic gradient marks the eastern edge of the Duncan Pluton, part of
the Black Lake Intrusive Suite which is the same age as the porphyry copper -molybdenum-gold
deposits at the Kemess deposits to the south.
• Location C. Strong, circular magnetic high within a broader more diffuse magnetic high that may
represent a volcanic dome or vent. Previous workers suggested the presence of a large shallow
subvolcanic dacitic dome east of the Shasta area and field observations this season gene rally
concur with that hypothesis, although further field work will be required to confirm this.
• Locations D and E. Distinctive northeast linear magnetic gradients are evident in the data and are
likely faults. Smaller faults with northeast orientations were observed offsetting mineralized veins
in the Shasta main Deposit Creek and JM open pits and are likely common throughout the area
based on the VLF data including at the Newberry Prospect (Figure 4).

This news release includes historical information that has been reviewed by the Company’s geological team and
qualified person. The Company’s review of the historical records and information reasonably substantiate the validity
of the information presented in this news rele ase; however, the Company cannot directly verify the accuracy of the
historical data, including the procedures used for sample collection and analysis. There is insufficient exploration on
these prospects to define a mineral resource. It is uncertain if after additional exploration a mineral resource will be
delineated . Therefore, the Company encourages investors to exercise appropriate caution when evaluating these
results.
The Cody Lee Zone has been renamed from the Christmas Creek Zone wit h the kind permission of his family, in honour
