TDG GOLD MOBILIZES FIELD TEAM TO GREATER SHASTA-NEWBERRY COPPER-GOLD PROJECT,

TOODOGGONE

Exploration scheduled to commence in June 2025 with IP followed by Drilling

White Rock, British Columbia, June 12, 2025 – TDG Gold Corp. (TSXV: TDG | OTCQX: TDGGF) (the

“Company” or “TDG”) is pleased to announce that its field team has mobilized and will shortly

commence TDG’s funded 2025 exploration program within the Company’s expansive and 100% -

owned Greater Shasta -Newberry (“GSN”) Project (Figure 1) in the Toodoggone District of British

Columbia (Figure 2).

Field activities will start with a combination of: (i) soil and rock geochemistry, (ii) Induced Polarisation

(“IP”) geophysics, (iii) Time -domain electromagnetic geophysics, (iv) ground based magnetic

geophysics and, (v) detailed geological mapping (Figure 3), followed by drilling, with the objective of

defining copper +/- gold drill targets. The initial focus will be on the area encompassing the Greater

Shasta, Newberry and AuW EST areas and will then expand to cover key parts of the 12 kilometre

(“km”) structural corridor previously defined by TDG (news release Mar 03, 2025). This corridor hosts

the Freeport-Amarc AuRORA1 discovery along with TDG’s Trident target (news release Mar 07, 2024)

and East Spur target (news release Mar 03, 2025).

HQ diamond drilling is expected to commence in mid-July with the first drillhole located less than 10

metres from the GSN-AuRORA1 boundary. A further two drillholes are expected to be drilled from the

same pad in close proximity to the mineral tenure boundary and the AuRORA 1discovery. Additional

pads, drillholes and drill rigs are expected to be deployed based on results from the targeting studies

as part of a proposed more extensive drill program at GSN and including additional targets prioritized

within the 12 km structural corridor.

Steven Kramar, TDG’s Vice President Exploration, commented: “TDG’s planned field program this

season represents a step change in our focus and cover age as we seek to evaluate and drill test a

number of copper +/ - gold porphyry opportunities on our side of the boundary of the AuRORA 1

discovery , and beyond. Operations will be based out of our Baker camp located ~8 km by road from

GSN. We are well -funded, and our camp is fully winterized – hence, we anticipate being able to

operate through to the end of October and into November, if warranted.”

pertaining to the Shasta Mineral Resource Estimate (“Shasta MRE”) contained in this news release is derived from the

Technical Report dated February 21 st, 2025 (with an effective date of December 29, 2024) titled “2025 Updated

Resource Estimate For The Shasta Deposit” (the “2025 Technical Report”) prepared by Sue Bird, MSc., P .Eng. of Moose

Mountain Technical Services. The information contained herein in r e spect of the Shasta MRE is subject to al l of the

About TDG Gold Corp.

TDG is a major mineral tenure holder in the Toodoggone District of north- central British Columbia,

Canada, with 100% ownership of ~50,000 hectares of brownfield and greenfield exploration ground.

In 2023, TDG defined the 5.5 sq.km Greater Shasta-Newberry exploration target area (news release

Jan 25, 2023) which is located directly adjacent to the gold-rich copper porphyry AuRORA1 discovery

announced by Freeport McMoran Inc. and Amarc Resources Ltd. (news release Jan 17, 2025).

In 2024, TDG identified new copper-gold target areas over an expanded footprint covering ~53 sq.km

known as the ‘Baker Complex’ (news release Feb 28, 2024 ), including the North Quartz (news

release Apr 02, 2024 ) and Trident (news release Mar 07, 2024 ) targets. In January 2025, TDG

identified an additional porphyry copper +/- molybdenum target at Erebus located within TDG’s Bot

project (news release Jan 17, 2025). In February 2025, TDG completed the Sofia acquisition, which

includes porphyry copper +/- molybdenum +/- gold targets (ARIS Report 41231).

TDG’s other projects within the property package include the former producing, gold -silver Shasta

and gold -silver-copper Baker mines, which produced intermittently between 1981 -2012, and the

historical high-grade gold Mets developed prospect, all of which are road accessible, and combined

have over 65,000 m of historical drilling. These projects have been advanced through compilation of

historical data, new geological mapping, geochemical and geophysical surveys and, at Shasta,

13,250 m of modern HQ drill t esting of the known mineralization occurrences and their potential

extensions. In 2025, TDG published an updated Mineral Resource Estimate 2 for Shasta (news

release Jan 08, 2025), which remains open at depth and along strike.

involve known and unknown risks, uncertainties and other factors that coul d cause actual events or results to differ

materially from estimated or anticipated events or results implied or expressed in such forward -looking statements. Such

factors include, among others: the uncertainty that any mineralization encountered on adjacent properties continues on to

TDG tenure; the uncertainty that geological and/or geophysical and/or geochemical anomalies and/or any trends,

interpretations, or conclusions based on adjacent prop erties have relevance to TDG’s tenure; whether geophysical

anomalies and targets located on TDG’s properties represent epithermal and/or porphyry -style mineralization and, if so,

whether such mineralization has economic potential; the actual results of current and planned exploration activities; the

actual timing of current and planned exploration activities; the interpretation that the Greater Shasta-Newberry Target Area

represents a larger mineralized system encompassing several target zones and the potential that such zones may represent

additional mineralized tar get zones; the interpretation that the 12 km structural corridor represents a larger mineralized

system encompassing several target zones and the potential that such zones may represent additional mineralized target

zones changes in project parameters as p lans to continue to be refined; accidents, labour disputes and other risks of the

mining industry; the availability of sufficient funding on terms acceptable to the company to complete the planned work
