VANCOUVER, British Columbia, April 01, 2026 (GLOBE NEWSWIRE) -- 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 metres. 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 indicates 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 quality 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.
