TDG Expands Recently Discovered ‘4300 Zone’ VMS Lens

Below Former Hidden Creek Mine at Anyox Project

Vancouver, British Columbia, April 01, 2026 – TDG Gold Corp. (TSXV: TDG | OTCQX: TDGGF) (the

“Company” or “TDG”) is pleased to announce additional drill results from the recently discovered

4300 Zone located below the past producing Hidden Creek Mine (1914-1935), at its 100% owned

Anyox Project located in the Golden Horseshoe of British Columbia.

To date, three diamond drill holes have intercepted the newly discovered mineralization, and the

4300 Zone remains open for expansion in all directions. TDG is well -funded with remobilization to

Anyox scheduled for mid-April to commence the next phase of drilling focused on new geophysical

targets identified from downhole electromagnetic surveys undertaken in 2026 (Figures 1-4).

4300 Zone: Drilling Continues to Expand on the Discovery

Building upon the previously reported intersection from the 4300 Zone discovery hole ANY-25-002,

which intersected 2.1% CuEQ1 over 25.1 metres, (1.5% Cu, 0.7% Zn, 0.21 g/t Au, 11.9 g/t Ag, 118

ppm Co ), recently completed drill hole ANY -25-003 intersected analogous grade and thickness

averaging 2.0% CuEQ1 over 25.7 metres, (1.1% Cu, 0.4% Zn, 0.37 g/t Au, 13.2 g/t Ag, 124 ppm Co).

This new intersection represents an 80 metre step out to the south from ANY-25-002 and now traces

the 4300 Zone over a drill defined strike of approximately 130 m etres. The 4300 Zone occurs at a

vertical depth of 900 metres below surface or 700 metres down dip below the lowest level of the past

producing Hidden Creek Mine.

The 4300 Zone remains open for expansion in all directions.

The Original 2025 Geophysical Plate Models – Correlation Established

Electromagnetic (“EM”) geophysical surveys are a proven and reliable exploration tool when

exploring for conductive volcanogenic massive sulphide (“ VMS”) systems such as those at Anyox.

The surveys allow for detection of EM conductors that could potentially be massive sulphide zones

‘outside’ of the drill hole and are ultimately modelled as rectangular plates that provide insight on the

potential extent of the EM conductors as well as the three -dimensional geometry. The geophysical

plate models derived from the 2024 extension hole ANY-24-003 led to the 4300 Zone discovery with

confident correlation between the recently drilled massive sulphide intersections and the originally

interpreted plate models.

The New 2026 Geophysical Plate Models – Expansion

The standard practice for the Anyox drilling program is to geophysically survey the completed drill

holes to gain new information that may optimize targeting success for subsequent drilling. Recently

interpreted plate models derived from the surveys completed on ANY -25-002 demonstrate

agreement with the original 2025 plates and indicate s that the conductors, which may represent

mineralization, extend both down dip below current drilling as well as along strike to the south

(Figures 1-4). The same can be said for the ANY -25-003 plate models which also exhibit similar

geometries and conductivities as those derived from the survey of ANY-25-002.

The next phase of drilling at Anyox aims to test for the potential downdip extension of the 4300 Zone

below the existing intersections.

A Recognized and Predictable Geological Environment

The rocks and mineralization processes of the Hidden Creek Deposits are typical of Besshi-style VMS

systems. Besshi deposits are copper -rich end members of the VMS spectrum and may also host

subordinate concentrations of zinc, gold, silver and cobalt.

Submarine volcanic rocks represent the original bedrock to the VMS mineralization with later

sedimentation extensively burying the entire system. However, the geological contact between the

underlying volcanics and overlying sediments may represent a prolonged geological time break

where the VMS mineralization may be deposited as lens shaped mounds on the former seafloor. This

horizon is where both the Hidden Creek deposit and the 4300 Zone mineralization are interpreted to

be located. The core of these lenses is typically copper dominated with lesser zinc concentrations in

contrast to the lens fringes where a halo of zinc abundance increases relative to copper.

Ramifications: Early Indications of a Larger System

The hole-to-hole progression of both lens thickness and tenor of the copper and zinc in the 4300 Zone

drill holes currently suggests that these holes may represent the outer limits or halo of a potential

larger massive sulphide lens. This potential is further supported by the location and geometry of the

geophysical plate models – the edge of the plates mimics the thinnest part of the zone intersected

by TDG during the extension to drill hole ANY-24-003 (news release February 23, 2026). Particularly

important is that a potential volcanic-hosted, copper-rich stringer or feeder zone has not yet been

identified by drilling. Such feeder zones, if present, are often indicative of the core of a lens.

Note that the No1 Lens at the now depleted Hidden Creek Mine measured 500 by 400 metres and up

to 75 metres in thickness2. This information is provided to illustrate the potential scale of VMS lenses

at Hidden Creek but is not necessarily indicative of the scale of the 4300 Zone.

Quality Assurance – Quality Control

Once received from the drill and processed, all drill core samples are sawn in half, labelled and

bagged. The remaining drill core is subsequently securely stored on site at the Project. Numbered

security tags are applied to lab shipments for chain of custody requirements. The Company inserts

quality control ( “QC”) samples at regular intervals in the sample stream, including blanks and

reference materials with all sample shipments to monitor laboratory performance.

Drill core samples are submitted to ALS Geochemistry’s analytical facility in North Vancouver, British

Columbia for preparation and analysis. The ALS facility is accredited to the ISO/IEC 17025 standard

for gold assays and all analytical methods include qu ality control materials at set frequencies with

established data acceptance criteria. The entire sample is crushed and 1 kilogram (“ kg”) is

pulverized. Analysis for gold is by 50 g fire assay fusion with atomic absorption ( “AAS”) finish with a

lower limit of 0.01 ppm and upper limit of 100 ppm. Samples with gold assays greater than 100 ppm

are re-analyzed using a 50 g fire assay fusion with gravimetric finish. A selected number of samples

are also analyzed using a 48 multi-element geochemical package by a 4-acid digestion, followed by

Inductively Coupled Plasma Atomic Emission Spectroscopy ( “ICP-AES”) and Inductively Coupled

Plasma Mass Spectroscopy (“ICP-MS”) and also for mercury using an aqua regia digest with ICP-AES

finish. Samples with sulfur reporting greater than 10% from the multi -element analysis are re-

analyzed for total sulfur by Leco furnace and infrared spectroscopy.
