TDG Discovers New ‘4300 Zone’ VMS Lens
Below Former Hidden Creek Mine at Anyox Project
Vancouver, British Columbia, February 23, 2026 – TDG Gold Corp. (TSXV: TDG | OTCQX: TDGGF)
(the “Company” or “TDG”) is pleased to announce the discovery of a new lens (4300 Zone) of
volcanogenic massive sulphide (“VMS”) Cu-Zn-Au-Ag-Co1 mineralization located below the past
producing Hidden Creek Mine, at its 100% owned Anyox Project located, in the Golden Horseshoe of
British Columbia.
The Hidden Creek Mine was discovered in 1901 and operated between 1914 -1935, with reported
historical productiona of 22 million to ns of 1.57% Cu (byproducts were not reported) . Mining was
completed to a vertical depth of ~300 metres before operations ceased due to low metal prices in
the Great Depression. Despite multiple studies between 195 0s-1990s, mining operations never
resumed at Hidden Creek and no modern exploration was undertaken until Anyox Copper Limited
conducted a 22-hole shallow drilling program in 2024 (NI 43-101 Technical Report published by TDG
in November 2025).
Two deeper drill holes completed by TDG have outlined the newly discovered mineralization and are
reported in this news release: 2024 drill hole ANY-24-003 was extended by TDG and then probed to
generate the geophysical target; ANY-25-002 is the first modern drill hole targeting the geophysical
“plate” that was generated. The 4300 Zone remains open for expansion in all directions. A third drill
hole (ANY-25-003) has been completed and is a southerly, 80 metre step -out from ANY -25-002.
Analytical results for ANY-25-003 are pending.
TDG is well -funded with exploration activities continuing . Anyox has tidewater access and can be
explored year-round. Hidden Creek, in combination with the defined VMS horizon that runs through
the Anyox Peninsula, represents a district-scale discovery opportunity for TDG.
4300 Zone: Defining the Next Chapter at Anyox
In an area never before tested by drilling or geophysical surveys, the 4300 Zone discovery drill hole
ANY-25-002 intersected a broad interval of massive sulphides grading 2.1% CuE Qb over 25.08
metres, (1.5% Cu, 0.7% Zn, 0.21 g/t Au, 11.9 g/t Ag, 118 ppm Co ). Higher grade sub -intervals
averaged 2.5% CuEQb over 14.80 metres, (1.8% Cu, 0.8% Zn, 0.25 g/t Au, 15.2 g/t Ag, 160 ppm Co),
including 2.9% CuEQb over 10.80 metres (2.1% Cu, 0.8% Zn, 0.29 g/t Au, 18.0 g/t Ag, 202 ppm Co ).
This intersection occurs at a vertical depth of 900 metres below surface or 700 metres down-dip
below the lowest level of the Hidden Creek Mine. An extension of 2024 drill hole ANY-24-003 to 1,025
metres provided the stimulus for this discovery via a highly conductive, off hole geophysical anomaly
identified from a survey performed in Q4 2025 . ANY-24-003 intersected 1.4% CuEQ b over 5.38
metres, (1.1% Cu, 0.7% Zn, 0.03 g/t Au, 9.4 g/t Ag, 0 ppm Co), and is located 80 metres up-dip to the
north from discovery hole ANY-25-002.
Fletcher Morgan, CEO, commented, “The discovery of the 4300 Zone confirms the broader potential
o f t h e A n y o x D i s t r i c t b e y o n d t h e h i s t o r i c H i d d e n C r e e k M i n e . O u r d i s c i p l i n e d , methodological,
capital-efficient exploration strategy has allowed us to rapidly advance this target while maintaining
a strong treasury. With the zone open in all directions and multiple additional geophysical targets
identified, we are well positioned to continue systematic expansion drilling in 2026. ”

Refining the Signal: From Conductors to Massive Sulphides
In 2025, the Company performed a deep penetrating electromagnetic (“EM”) geophysical survey over
its land holdings in the Anyox District that resulted in multiple new targets. Most importantly, a large,
highly conductive anomaly at depth below the past -producing Hidden Creek Mine was discovered.
This very broad anomaly required additional refinement to help constrain its geometry and as such,
three drill holes from the 2024 drilling program were extended (1,321 metres total), for the purposes
of increasing confidence with more expansive downhole EM coverage. Although new anomalies were
identified proximal to the Hidden Creek Mine, the largest, most conductive plate model was an off-
hole anomaly below 2024 extended drill hole ANY-24-003 which intersected 1.4% CuEQb over 5.38
metres, (1.1% Cu, 0.7% Zn, 0.03 g/t Au, 9.4 g/t Ag, 0 ppm Co) . Two geophysical anomalies (plate
models) were detected, measuring up to 400 by 200 metres (“m”). The occurrence of a new massive
sulphide intersection in ANY-24-003, paired with new off hole conductors in an area never historically
drilled necessitated further investigation.
A Recognized and Predictable Geological Environment
The rocks and mineralization processes of the Hidden Creek d eposits are typical of Besshi VMS
systems. Besshi deposits are copper-rich end members of the VMS spectrum and 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 represents a prolonged geological time break where
the VMS mineralization was deposited as lens-shaped mounds on the former seafloor. This horizon
is where both the Hidden Creek deposit and 4300 Zone are located. The core of these lenses is
typically copper dominated with lesser zinc concentrations, as opposed 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 copper and zinc in the 4300 Zone
drill holes currently suggests that these holes represent the outer limits, or halo, of a larger massive
sulphide lens. This interpretation is further corroborated by the location and geometry of the
geophysical plate models – the edge of the plates mimics the thinnest part of the zone as defined by
ANY-24-003. Particularly important is that a volcanic-hosted, copper-rich stringer or feeder zone has
not yet been identified by drilling. The feeder zone is often indicative of the core of a lens. Note that
the No1 Lens at the now depleted Hidden Creek Mine measured 500 by 400 m and up to 75 m in
thickness2.
Unlocking the Next Phase of Growth
Geophysical crews are currently performing downhole electromagnetic surveys on the two newly
completed holes. Once completed , amalgamation of the new data and refinement of the plate
models will be performed to pragmatically guide the next drilling program. Drilling of the 4300 Zone
will resume in March 2026 once new targets have been developed and after a logistical resupply has
been completed.

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 quality control materials at set frequencies with
established data acceptance criteria. The entire sample is crushed and 1 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 Inductively Coupled
Plasma Atomic Emission Spectroscopy (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.
