Taranis Quantifies Hydrothermal Alteration System at Thor to Improve Targeting for 2025 Deep
Exploration Drilling
Estes Park, Colorado, April 9, 2025 – Taranis Resources Inc. (“Taranis” or the “Company”) [TSX.V:
TRO, OTCQB: TNREF] is providing the fourth in a series of updates related to the 2024 deep drilling
program at Thor , SE British Columbia . Taranis has finalized a mass-balance alteration study of the drill
holes completed in 2024 , which intersected the I-1 and I-2 intrusive rocks that contain anomalous gold,
zinc, and arsenic . Mass-balance (“Gresen”) alteration analysis is a well-known tool in measuring
hydrothermal alteration for deeply buried intrusive targets. This method identifies large-scale geochemical
changes (mass and volume changes) related to the hydrothermal alteration that accompan ies intrusive-
related mineral deposits. Using this method, Taranis can minimize future drilling costs by identifying areas
of intense hydrothermal alteration. This approach is particular ly useful when combined with
magnetotelluric surveys that have already identified concealed targets. A 3D block model accompanies this
News Release, showing the magnetotelluric model with the mass/volume geochemistry conducted in the
2024 drill holes.
Taranis completed specialized sampling of 252 drill core samples and a number of surface samples. These
samples were analyzed for major elements, trace elements and rare-earth elements. At Thor, Light Rare
Earth Elements (“LREE”) are geochemically immobile, and these were used to construct isocons for each
sample that measured the gain/loss of other chemical components in the rock. These were compared with
visibly unaltered populations of rock including pelites, greywackes and calc -alkaline intrusiv e dyke s.
Mass/volume depletion is diagnostic of ‘leaching’ of the original host rock, whereas mass/volume addition
is characteristic of deposition in the host rock by hydration, carbonation or the addition of quartz-carbonate
veins. At Thor, areas of ma ss/volume gain are particularly sought after, as an underlying intrusive would
have added silica, sodium, carbonate and other chemical components that commonly accompany metals
such as gold, silver, zinc, lead and copper. Areas of mass/volume addition are are as which exploration
should be directed as these will also have precious and base metal mineralization.
Epithermal Deposit
The epithermal veins at Thor that constitute the current Mineral Resource exhibit mass gains due to the
introduction of silica, carbonate and other gangue minerals such as paragonite. Various other economically
important sulfides including silver-bearing tetrahedrite, auriferous pyrite, sphalerite and chalcopyrite have
also been introduced into the veins with the influx of hydrothermal fluids . From an alteration perspective,
the chemical changes associated with these veins are relatively localized. The alteration zones around the
epithermal veins show high mass/volume depletions indicating the wall rocks around the veins were leached
by the hydrothermal fluids. In these mass/volume depletion zones, there is an increase in carbon (graphite)
around the polymetallic veins, and this can be identified by geophysical surveys that measure conductivity.

The “Spider Hole” - Intrusive Rocks, and Widespread Alteration Zonation
The most important part of the alteration study focused over an area where an airborne magnetotelluric
survey identified a prospective deeply buried intrusive target. This survey also identified a large conductive
halo that surrounds the intrusive target, and it is conductive. Drill Hole Thor -242 intersected some of the
rocks associated with this feature and they contain 3-4% graphitic carbon. The circular nature of this feature
(North and South Tusks) is shown on the image included in this News Release, and its configuration
suggests that it encircles an intrusive body. The wall rocks around the mineralized veins in the epithermal
deposit have pronounced mass/volume depletions (80-100%) and very high levels of graphitic carbon. By
analogy, the North and South Tusks at Thor are most likely encapsulating the buried I-1 intrusive target.
This conductive feature that measure s 2 km in diameter is interpreted to be related to a very large, buried
feature that was the probable source of hydrothermal fluids at Thor.
It is not uncommon to find intrusive bodies associated with epithermal deposits, and this association forms
the basis of the ‘linked epithermal-porphyry model’ that originally led to Taranis to explore for the source
of the epithermal deposit. The 2024 deep drilling identified many new rock formations that are commonly
associated with contact alteration around an intrusive including the I-2 intrusive dyke system, and the I-1
contact-altered rock unit. D rilling was conducted in an area roughly 1 km south and east of the Thor
epithermal deposit over a prominent resistivity-high feature called the ‘Spider Hole’. The drill holes in this
area show mass /volume gains indicative of widespread hydrothermal alteration over hundreds of meters .
The formations show an influx of Silica (SiO2), Sodium (Na2O), Calcium (CaO), Carbonate (CaCO 3) and
Total Iron (Fe2O3). Other elements added to these rocks by hydrothermal fluids include arsenic, zinc, gold
and boron. The most striking aspect of the alteration study at Thor is the progressive mass/volume increase
with depth associated with the I-1 and Z-900/1300 targets. In drill core, this is seen as an increase in albite,
quartz, grossular-andradite garnet, amphiboles and carbonate. These mass /volume positive areas are also
enriched in gold, arsenic, zinc and boron.
Comment
John Gardiner, President and CEO of Taranis comments “The focus of future exploration at Thor is to find
a large intrusive-hosted deposit that is enriched in precious and base metals that is connected to the Thor
epithermal deposit. Exploration for concealed intrusives is classically done through the use o f
magnetotelluric surveys. Although we were not able to test the Z -900/1300 target last summer, this target
has a geophysical signature that would suggest widespread silicification and albitization . Permitting is in
process that will allow it to be tested from the main access road at Thor.
Moving away from the Z-900/1300 and I-1 targets, the metavolcaniclastic and metasedimentary host rocks
become increasingly less -altered, and are characterized by neutral or slightly negativ e mass/gain losses
indicative of leaching. This is consistent with a large buried intrusive body where the host rocks distal to
the intrusive have been leached and have lost CaCO 3, SiO 2, CaO and K 2O relative to their unaltered
equivalents”.
Quality Control and Laboratory Methods
All samples for the Thor project were securely delivered to Actlabs in Kamloops, British Columbia.
3
Analytical work was completed both at the Kamloops and Ancaster, Ontario locations. Actlabs is ISO 17025
accredited. Taranis completed two types of geochemical analysis on the drill core.
Soil Samples were collected in the field using a gas-powered auger, and stored in soil sample bags that were
subsequently dried in the field . They were analyzed for 42 elements by 4 -Acid Digestion / Inductively
Coupled Plasma - Mass Spectrometry (“ICP-MS”) and for gold by 30g Fire Assay / Atomic Absorption
Spectrophotometry (“AAS”).
Visibly (or potentially mineralized sections of core) were systematically sampled after sawing the
core in half onsite. Samples were analyzed for 42 elements by 4-Acid Digestion / Inductively Coupled
Plasma - Mass Spectrometry (“ICP-MS”) and for gold by 30g Fire Assay / Atomic Absorption
Spectrophotometry (“AAS”). Where overlimit values were encountered in the anal ysis of these samples,
ore-grade’ determinations were made using subsequent ICP analysis and gravimetric methods. As a Quality
Control (“QC”) measure, Taranis also submitted analytical standards into the sample stream every tenth
sample in addition to the laboratory’s own quality control methods.
