Taranis Announces New Critical Minerals By-Product Findings at the Thor and Ajax Mines

Estes Park, Colorado, August 17, 2026 – Taranis Resources Inc. (“Taranis” or the “Company”) [TSX.V:

TRO, OTCQB: TNREF] is releasing the results of a study o f by-product metals found at Thor . Samples

were collected from a stockpile of vein material at Thor, and from adit dump s at another historic mine

(Ajax) located across a valley . Identical analytical processes were applied to the samples from both

locations with results demonstrating that consistent enrichment of epithermal-style precious and critical

minerals has occurred at both sample sites. The findings of the study strongly indicate further exploration

activities between the two historical mine sites and further indicates that a single enrichment event is

responsible for the existence of both mineral deposits.

Background

Taranis has a defined near-surface NI 43-101 Mineral Resource at Thor that includes gold, silver, copper,

lead, and zinc as core commodities . The most recent NI -43-101 updated Mineral Resource (see Taranis

2

News Release dated February 26, 2024) was prepared with a focus on these core metals. Two of the existing

metals contained in the updated NI 43 -101 Mineral Resource are defined as Critical M inerals by the

Canadian Federal Government ( copper and zinc). Several other critical minerals are present in the Thor

mineral resource, including indium, antimony, and gallium. The Canadian Federal Government announced

an agreement with the Canada Growth Fund in July 2026 to fund local (Trail, BC) processing capacity for

these three elements.

Being a polymetallic deposit, Thor contains other metals of value commonly called ‘by -product metals’,

and these typically only occur in minor concentrations. These are metals that could never be economically

mined for their own sake - but are recovered incidentally with the core metals. This means that the ability

to recover these by-product minerals is only feasible if the main metals in the deposit are economic to mine.

Context of Critical Mineral Sampling Undertaken

Taranis investigated ‘by-product’ metals at both the Thor and Ajax deposits , which are located within the

expanded Thor property (6,470 ha). The samples are selective and are not representative of the average

metal content of the deposits. The True Fissure samples were collected at the Thor open pit (464782E,

5617129N), and the Ajax samples were taken from 468477E, 5614842N UTM Zone 11N).

At Thor, sampling was conducted in the True Fissure zone, which forms part of the existing Thor Mineral

Resource. The data presented here identify ‘by-product’ metals that occur in sufficient quantities to warrant

consideration as by-product metals, but further study is needed to establish average concentrations.

The current updated Mineral Resource at Thor includes gold, silver, copper, lead, and zinc; however, the

sampling discussed in this News Release suggests that indium, cadmium, antimony, and other metals should

be considered in future Mineral Resource updates. Properly assessing the quantities of by-product metals

in the Thor deposit will require additional, highly specialized analytical techniques that have not been

systematically applied at Thor . Taranis has permitted a 10,000 -tonne bulk sample that would more

accurately define the concentration, mode, and occurrence of these by-product metals.

The discovery of broad similarity between material at Thor and Ajax has important implications for future

exploration, as it suggests the deposits originated from the same source - most likely an intrusive body (or

series of intrusive bodies) located in contact with the Silver Cup Anticline (see the figure that accompanies

this News Release).

Ajax Mine

The Ajax Mine is located 4.4 km east-southeast of the Thor Deposit, across Ferguson Creek. Taranis owns

contiguous Mineral Tenures that cover both the Thor and Ajax mines. No NI 43-101 Mineral Resource has

ever been completed at Ajax or the adjacent Nettie L. Mine. Ten (10) samples were collected from the

dumps found at Ajax, and the rocks were sawed in half, petrographically described, and subjected to

multiple types (see analytical methods outlined below) of analysis to ascertain the presence of ‘by-product’

metals.

The Ajax Mine can be described as a high -grade precious and base metal deposit of epithermal character.

As with Thor, the main metals of interest in the deposit are gold, silver, copper, lead and zinc:

Additional work is required to find out how these by-product metals occur in the Ajax Deposit. In general,

it is understood that indium occurs with sphalerite, and both cadmium and antimony occur with tetrahedrite

(silver). It is unknown which minerals host gallium, neodymium and tin, nor if they are potentially important

by-products of precious and base metal extraction.

Thor Deposit

Taranis has established an NI 43-101 Updated Mineral Resource at Thor. The precious metal content (gold

and silver) is well-documented, as are the base metals copper, lead and zinc. The following table shows the

average content of these metals from thirteen (13) samples collected from the True Fissure Open Pit.

Thor contains similar levels of ‘by-product’ metals, albeit slightly higher levels of antimony than the Ajax

deposit samples.

Discussion

4

Despite lateral separation of 4.4 km, both Thor and Ajax have comparable metal contents, including

potential by -product metals. In-depth analytical work and strong domestic investment in processing

technologies suggest that antimony, indium and cadmium should be examined as ‘by -product’ metals in

future updates to the Thor Mineral Resource. Gallium and tin also occur in both Thor and Ajax, but their

habits and recoverability are enigmatic at this point. One point of difference between the deposits is the

lack of neodymium and gadolinium at Thor.

Thor is a relatively unusual deposit in that it contains many different core metals. It is located near surface

and is relatively high-grade compared to other deposits commonly found in British Columbia. High-grade

mineral deposits are extremely valuable - even when size is small – because the value per tonne is high and

the surface footprint of the mine is considerably smaller than a large, low grade, bulk mineable deposit.

Sampling outlined in this report suggests that even higher value/tonne can be reasonably inferred by

considering the contributions of ‘by product’ metals. Deposits such as Thor and Ajax are strategically

valuable deposits because they are literally a ‘one-stop shop ’ for many of Canada’s favourite precious

metals, alongside increasingly in-demand Critical Minerals.

Quality Control and Laboratory Methods

All samples for the Thor project are securely delivered to Actlabs in Kamloops, British Columbia.

Analytical work was completed both at the Kamloops, and Ancaster, Ontario locations. Actlabs is ISO

17025 accredited. Rock Samples are bagged and identified with a laboratory ticket, and the location of the

samples is noted with a differential GPS unit. 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”). In addition to this, the samples were also analyzed using

Instrumental Neutron Activation Analysis ( “INAA/FINA”) to determine osmium, ruthenium, rhodium,

platinum and palladium content. Overlimit silver, lead, zinc and sulfur determinations were analyzed using

a combination of gravimetric and “total” Fusion (“Peroxide ICP-OES”) methods.

Qualified Person

Exploration activities at Thor were overseen by John Gardiner (P. Geo.), who is a Qualified Person under

the meaning of Canadian National Instrument 43-101. John Gardiner is the principal of John J. Gardiner &

Associates, LLC which operates in British Columbia under Firm Permit Number 1002256. Mr. Gardiner is
