TDG GOLD CORP. INTERSECTS PORPHYRY STYLE MINERALIZATION AT OXIDE CREEK, TOODOGGONE

DISTRICT, B.C.

White Rock, British Columbia, June 01, 2023 - TDG Gold Corp. (TSXV: TDG) (the “Company” or “TDG”) is

pleased to announce the results of the 2022 exploration program at it’s earn-in Oxide Peak Project in the

Toodoggone district of north-central British Columbia. The program included over 1,000 metres (“m”) of

diamond drilling in two holes at the Oxide Creek target, along wit h airborne hyperspectral analysis

covering the entirety of the Oxide Peak property. Oxide Creek represents a highly prospective target for

the discovery of a porphyry copper style deposit, with stream and rock sampling indicating the typical

zonation of a copper (“Cu”) enriched core surrounded by z inc and lead on the peripheries, highly

sulphidized (pyrite) and quartz-sericite alteration giving a common QSP signature, evidence of magnetic

destruction common in large hydrothermal systems and clay mineral assemblages that are zoned, and

coincident with, anomalous Cu +/ - gold (“ Au”) mineralization. The two drillholes completed in 2022

provide a third dimension to the alteration, mineralization and mineral assemblages seen on surface,

suggesting the presence of a large-scale mineralizing system nearby.

The Oxide Peak mineral tenures comprise over 8,000 hectares of highly prospective mineral claims located

adjacent and contiguous to the north of TDG’s former producing gold-silver Baker mine property (Figure

1). TDG has identified multiple exploration targets1 on the Oxide Peak Project, including Drybrough (drilled

by TDG in 2021) and Oxide Creek (drilled by TDG in 2022).

Highlights:

• 1,021.5 m of drilling completed in two diamond drillholes (“DDH”), both holes intersecting broad

intervals of anomalous concentrations of base and precious metals associated with an assemblage

of high to medium sulphidation minerals (Table 1).

• Pathfinder elements (tellurium, tungsten, bismuth) suggest the presence of a porphyry system

nearby the 2022 drilled area1.

• Ground and airborne geophysics (including the 2022 hyperspectral analysis) indicates a large

hydrothermal system in the vicinity of Oxide Creek1.

Chris Dail, a technical consultant leading TDG’s regional program, commented: “Our initial drill test of the

large Oxide Peak system is encouraging with visible alteration over 200 m of vertical extent in intensely

sulphidized rock, associate d with highly anomalous copper, zinc and molybdenum concentrations

throughout both drillholes. The large and coincident geophysical and geochemical anomalies on the

property are open in both directions, down dip and we have yet to test the larger copper in soil anomaly

and outcropping of porphyry copper style alteration found downhill from the target we drilled in 2022.”

2022 Diamond Drilling & Exploration Summary

Two HQ/NQ diameter DDH were completed towards the end of the 2022 field season, totaling 1,021.5 m.

The two DDH completed targeted a short portion of a coincident 0.5 kilometre (“km”) wide x 2 km long

induced polarization (“IP”) and aeromagnetic geophysical anomaly associated with a broad multi-element

geochemical anomaly and mapped advanced argillic to intermediate argillic alteration assemblages. Both

DDHs, intersected multiple, broad intervals of high to intermediate sulphidation mineral assemblages

containing highly anomalous concentrations of Cu, zinc (“Zn”), molybdenum (“Mo”) and locally lead (“Pb”)

and Au along with a suite of porphyry -style pathfinder elements (tellurium, tungsten and bismuth “ Te”,

“W” & “Bi”) and strong quartz sericite (illite) -pyrite (“QSP”) style alteration. The combined data is

suggestive of the presence of a porphyry Cu-Mo system in the vicinity1. Select intercepts are presented

in Table 1 with DDH particulars in Table 2. Full DDH composite results are provided in Table 3.

Past Exploration of Oxide Peak Target Area

Mineralization in the Oxide Peak area was recognized in the 1930s when nearby placer operators

conducted stream sediment sampling and initial prospecting throughout the area. In the mid -1930s,

Cominco reportedly identified the mineralization in the area during regional surveys. In the 1980s SEREM

identified a broad area of highly anomalous stream sediment samples and traced the anomalous samples

to their source area on a large iron oxide-stained ridge known as Oxide Peak.

A number of mineral occurrences1, including Oxide Peak are now known to occur along a north-northwest

trending, poorly exposed, 10 -km long belt of intense QSP altered volcanics and intrusive rocks, gossans

and multiple dike swarms with variable compositions exhibiting alteration types and patterns typical of

the upper levels of porphyry Cu-Mo systems. These altered and mineralized zones occur along the Takla-

Toodoggone volcanics contact - a permissive and favorable site for porphyry systems within the

Toodoggone Belt.

In 2020, TDG completed a detailed airborne radiometric and magnetic survey over the Oxide Pea k

property on 100 m line spacing. Ground survey work, including soil geochemistry and an IP survey and

ground magnetic surveys.

These surveys outline a large multi -element geochemical anomaly coincident with the geophysical

anomalies and mapped alteration . In mid -2022, a high precision airborne hyperspectral survey was

conducted over the property to assist in mapping alteration mineralogy at the property scale. These

surveys outlined a broad area exhibiting anomalous airborne hyperspectral signatures indicative of a large

hydrothermally altered area, consistent with on-the-ground field observations by past operators and the

TDG exploration team1.

Interpretation of Hyperspectral (SWIR) Survey Data

Previous operators conducted limited short wave infrared reflectance (“SWIR”) analyses of outcropping

exposures of altered intrusive, volcanics and volcaniclastics rocks on and adjacent to the property,

identifying the presence of weak to moderate advanced argillic alteration including diapsore and

pyrophyllite. These assemblages are typically found at high levels in hydrothermal systems, often

associated with porphyry deposits. The zonation of major and trace elements and chemistry and

crystallinity in mus covite, illite (a fine -grained white mica) and chlorites are typical of the alteration

footprint for porphyry deposits and may provide an exploration tool for vectoring towards mineralization.

Chemical variations in the chlorites and illites are partly reflected in the SWIR spectra in samples from

Oxide Peak drilling and outcrops.

The aerial hyperspectral surveys at Oxide Peak provided dense, high quality hyperspectral (SWIR) data in

the areas devoid of vegetation. The airborne surveys outline a large 500 m x 500 m multi -mineral

hyperspectral anomaly that is open in all directions into vegetation covered areas centered on the area of

the 2022 drilling. Processing of the spectral data indicate the illites and chlorites within the zone exhibit

higher levels of crystallinity, suggesting high temperatures of formation, consistent with the drill results

in the highly altered and sulphidized zones. High -temperature illite is suggestive of a nearby buried

intrusion or alteration by higher temperature hydrothermal fluids 1. The survey data also indicates the

presence and zonation of phengitic to paragonitic illites which reflect the underlying chemical composition

of the fine -grained white mica species. Chlorite, like illite, shows systematic variations in its chemical

composition, which, among other exploration tools, are related to the formation temperature. High iron

(“Fe”) chlorite is the dominant chlorite type present in the hyperspectral survey of the prospect, but

variations exist and may reflect subtle zonation patterns as well. Fe-rich gossans occur throughout the hill

and are coincident and larger than the illite anomaly.

The hyperspectral data indicates the gossans in the drilled area are goethite dominant, hematite

subordinate gossans are found on the wester n portions of the ridge with minor jarosite occurrences

throughout the area. These variations may represent primary sulphide and rock composition variations,

and may be related to alteration zonation and/or reflect weathering effects.

The hyperspectral analysis has also identified anomalous SWIR signatures in several north -northwest

trending linear belts passing through the TDG properties including Oxide Peak. These a nomalous

hyperspectral features likely represent hydrothermal alteration zones potentially centered on subvolcanic

intrusive rocks. A large area at TDG’s past producing Baker Mine Complex (including the Drybrough target

on the Oxide Peak property block) exhibit similar highly anomalous hyperspectral signatures and

correspond with strong base and precious metal sample results from stream sediment sampling surveys

by previous operators and TDG. Large poorly explored and undrilled geochemical, airborne geophys ical

and hyperspectral anomalies are also present elsewhere on the Oxide Peak property1.

2022 Diamond Drilling at Oxide Creek

In late summer 2022, an initial two drillhole program targeted a coincident zone of: (i) outcropping weak

to moderate advanced argillic alteration assemblages identified by previous operators using hand -held

SWIR instrument including pyrophyllite, diaspore, alunite, and kaolinite, (ii) a broad multi- element soil

anomaly (Au, Cu-Figure 2, Pb, Zn, As), (iii) outcropping Fe oxide gossans, (iv) a linear northwest trending

ground magnetic and aeromagnetic anomaly and, (v) a coincident 0.5 km wide x 2 km long IP chargeability

anomaly.

Drilling successfully demonstrated the presence of seven lenses of intense illite-sulfide (pyrite) alteration

hosted in intermediate to felsic volcanic and volcaniclastic rocks and possible intrusive dikes. These

sulphidized zones range from approximately 5 m to 78 m drilled thickness and typically contain from 5-35

% pyrite with traces of bornite, chalcocite and occasional sphalerite. Cumulative thicknesses of these high

sulfide content zones averages approximately 240 m drilled thickness between the two d rillholes. The

sulphidized assemblages are associated with zones of intense fracturing and illite alteration (Figure 3).

An oreXpress® portable SWIR scanner was utilized to characterize clay mineral assemblages and indicate

high crystallinity illites are d irectly associated with and correlate well with the altered and sulphidized

zones. Highly anomalous Au, Ag, Cu, Pb, Zn, Bi, Mo, Se, Te, and arsenic (“As”) are associated with the

intensely altered zones, typical of many porphyry Cu-Mo systems in the region and elsewhere. Extensive

gypsum (calcium sulphate) veining was abundant in both holes at increasing depth. Gypsum veins and

stockworks are often developed in the higher levels of subvolcanic porphyry systems. Structural

information on veins, contacts and other structural elements collected during oriented core drilling is

consistent with the geochemically and geologically interpreted mineralized zones.

Systematic magnetic susceptibility measurements on core indicates zones of alteration and sulfide

enrichment generally have low magnetic susceptibility suggesting destruction of primary magnetite and

mafic minerals during hydrothermal alteration. Magnetite-bearing intermediate to felsic porphyritic dikes

locally crosscut the mineralized zones and have high magnetic susceptibility and are typically strongly

magnetic. Zn and Cu concentrations demonstrate apparent zonation with higher Zn concentrations

towards the top of the holes and higher Cu concentrations at depth and down dip towards the east -

where a large 500 m x 500 m Cu -in-soils anomaly remains untested (Figure 2). Some of the porphyritic

dikes also host Zn-rich mineralization suggesting multiple intrusive-related mineralization phases may be

present1. Zn is often found in the distal portions of porphyry-Cu systems.

The upper portions of both holes intersected vuggy silica sucrosic textured oxidized to partially oxidized

and mont morillonite and illite altered intermediate to felsic volcanic and volcaniclastic rocks.

Montmorillonite and jarosite were common towards the top of both holes and were generally absent at

depth. In the altered zones intersected in drilling, textures are often partially or completely obliterated by

the intense alteration and dense fracturing. The geochemical data, textures and mineralogy suggest the

holes likely penetrated distal porphyry -type alteration assembl ages. This is consistent with and

encouraging since intrusive hosted hydrothermal breccias with quartz -magnetite-chalcopyrite veins and

relict potassic alteration outcrop at Oxide Creek along the northern end of the IP anomaly at lower

elevations as does a large Cu-in-soils anomaly to the southeast and likely down dip on the sulfide -rich

lenses.

QA/QC

Samples for the Oxide Peak 2022 drill program were handled via rigorous chain of custody, between

collection, processing, and delivery to the SGS laboratory in Burnaby, B.C. The drill cores were delivered

to the core shack at TDG’s Baker Mine site and processed by geologists and technicians who verified down

hole meterage blocks, photographed the core, recorded recovery, Rock Quality Data (“RQD”), logged

lithology, alteration and captured oriented core structural information, inserted certified reference

materials (“CRM’s”), blanks and duplicates (coarse) into the sampling sequence. The 2022 drill core was

cut in half (1/2 HQ/NQ core) 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 SGS’ facility in Burnaby, B.C. Samples were prepared and analyzed

following procedures: GE_FAI50V5, GE_ICP21B20/GE_IMS21B20, GE_ICP90A50/GE_IMS90A50 and

GE_CSA06V for sulphur and carbon analysis. Information about methodology can be found on the SGS

Canada Inc. website, in the analytical guide(here).

Quality assurance and control (“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 insertion and verification of lab results via use of certified reference materials (“CRMs”),

duplicate samples and blank (unmineralized) samples that were blindly inserted into the sample batch. If

a QAQC sample returns an unacceptable value an investigati on 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.
