Taranis Details What Lies Under Thor – A Lamprophyre Intrusive and Related Alteration That

Has Direct Affiliation with Calc-Alkaline Epithermal Deposits

Estes Park, Colorado, December 29th, 2025 – Taranis Resources Inc. (“Taranis” or the “Company”)

[TSX.V:TRO, OTCQB:TNREF] is providing a summary of ongoing exploration results from its Thor

Property. In 2024, Taranis initiated a deep drilling program under the south end of the Thor deposit that

tested a number of aeromagnetic and magnetotelluric (“MT”) resistivity anomalies t hat underly the Thor

deposit. The source of these anomalies is now known to be lamprophyre intrusive rocks and accompanying

alteration. The presence of lamprophyres at Thor, and the Silver Cup Mining District in general are

indicative that the district has potential to ho st world-class calc -alkaline epithermal deposits similar to

Cripple Creek in Colorado, and Golden Sunlight, Montana. The deposit is known to be intruded by this

younger lamprophyre dyke system, and is ‘cut-off’ at depth by the intrusive. The 2025 discovery of the Borr

Zone on the east side of the lamprophyre dyke -alteration system indicates that the epithermal deposit

remains intact at depth and open. This finding offers unprecedented potential to expand the Thor deposit at

depth and is where Taranis will focus on drilling in the foreseeable future. In a larger sense, it shows as a

graphic example as how modern exploration methods such as deep drilling, geophysics and geochemistry

can be integrated to revitalize exploration in old mining districts and expand on previously known mineral

deposits.

Lamprophyre Intrusive at Thor

Lamprophyre intrusives have never been described before in detail within the Silver Cup Mining District ,

although they are known elsewhere in Southeast British Columbia (Salmo, Golden). These intrusive rocks

are derived from the mantle and are commonly porphyritic and a ccompany intrusive breccias. The dykes

are mafic in composition and have high levels of magnesium, nickel, copper and chromium. Lamprophyres

at Thor are linear, steeply dipping dyke-shaped bodies that have intruded into intensely -folded lower

Paleozoic-age metasedimentary and metavolcaniclastic rock units. The main lamprophyre body and the

epithermal deposit clearly cross-cut the older Silver Cup Anticline. Modelling of the deposit and the

intrusive dyke-alteration system show that the intrusive has ‘punched-through’ and intruded the epithermal

deposit essentially breaking it into two halves. The west (upper) half is the currently known Thor deposit ;

and the east (lower) half was discovered in 2025 and is now called the Borr Zone (See Taranis News Release

October 27, 2025)

Alteration Related to Lamprophyres

The lamprophyre -related alteration zones can be identified and mapped using airborne geophysical

magnetic and MT surveys, and constitute the main targets that were drilled in the 2024 and 2025 drilling

programs. While the lamprophyre dykes themselves are relatively thin (meters), the metasomatism

associated with the dykes is volumetrically large and this metasomatism can extend tens of meters away

from the lamprophyre dykes themselves . Some of the lamprophyre-related alterations include the

introduction of magnetite into the host rocks, introduction of g arnet (grossular-andradite), chloritization,

2

albitization, carbonatization and pyritization. Other lamprophyre-unique alteration features also include

ocelli, and gold-bearing fuchsite along the edges of the lamprophyre dyke . In one drill hole (Thor-256), a

magnesite carbonatite intrusive body is associated with lamprophyre.

Relationship to Conductivity Tusks at Thor

In 2022, MT identified two large conductivity features that are spatially related to the lamprophyre. The

North and South Tusks bracket the lamprophyre body and its associated alteration. In one area w here the

North Tusk is exposed near surface north of Thor’s Ridge (Megagossan), the extensive gossan is enriched

in iron, nickel, copper, chromium and the host rocks are graphitic. This demonstrates that the lamprophyre

intrusive rocks had widespread thermal alteration that extended upwards of 1km away from the dyke itself.

The source of the conductivity anomaly is conductive carbonaceous material derived from ‘cooked’ organic

matter in the host metasedimentary rocks.

Comments

Lamprophyre rocks are known to be genetically associated with some of the largest (calc -alkaline)

epithermal deposits in North America , and are also associated with silver-rich base metal deposits

(Tonopah, Nevada). The presence of lamprophyres is direct evidence that a deep structure tapped-down into

the mantle under Thor and provided the heat engine to the hydrothermal system that formed the lamprophyre

dyke, but almost certainly the epithermal deposit itself. As such, once the epithermal deposit was emplaced

and the intrusive-related system continued to evolve, mantle derived lamprophyre intrusive rocks intruded

the epithermal deposit, cutting it in half. This fully explains one of the enduring mysteries encountered at

Thor when miners in the 1930’s drove a major 1 km long exploration tunnel (Morgan Tunnel) downdip of

the epithermal deposit, and encountered no mineralization. Unknowingly, they had driven the exploration

adit along the west edge of the lamprophyre dyke where the deposit had been intruded and consumed by

the lamprophyre dyke-alteration system.

Despite the Silver Cup Mining District having been explored and mined for upwards of 100 years, there has

been no direct mention of these important intrusive bodies. Some of the previous workers described these

rocks as the “Middle Volcanic Member of the Broadview Formation”, so although they were recognized as

being volcanic in origin – no one recognized them as being intrusive. The Silver Cup Mining District has

historically been classified as a bunch of silver -rich veins broadly associated with a feature known as the

Silver Cup Anticline but of no obvious origin. What our exploration work at Thor has demonstrated is that

these deposits are in fact calc-alkaline intrusive-related deposits, and as such have close affinity to some of

the largest epithermal deposits in North America. Taranis has assembled a substantial land position (6,500

Ha) in the Silver Cup District over some of the most prospective historic deposits recognizing that historic

mining has only “scratched the surface”.
