Fougnar TEM and IP Survey Results

 

 

Dublin, Ireland, 16 April 2026 - Talisman Metals PLC ("Talisman" or the
"Company") reports it has completed a 74 line-km, TEM survey (Transient
Electromagnetic) ("TEM Work") covering 18 km(2) within the Company's Fougnar
licenses ("Fougnar Project"), which are 25km west of the Tizert copper-silver
mine, see Figure 1. The TEM Work, in combination with historical trenching
work and mapping, confirms Fougnar as a sediment-hosted copper-silver mineral
system and has resulted in the identification of 11 high-priority
copper-silver exploration targets which will be followed up by the Company in
its dedicated exploration program scheduled for summer 2026. Talisman believes
that the sediment rock formations at Fougnar have excellent potential to host
a large sediment-hosted copper-silver deposit, similar to other such deposits
in the Anti-Atlas area of central Morocco.

 

Tim McCutcheon, Talisman's CEO stated, "The Fougnar Project offers great
potential for Talisman to demonstrate a sediment-hosted copper-silver project
of merit quickly. Given the past work and the very nature of sediment-hosted
deposits, many risk factors are removed or have been addressed. One, we know
we have copper-silver mineralisation. Two, based on previous sampling of
outcrops we know the material that contains these desirable metals has grades
that could be economic.  Three, we have a license package that has the
necessary scale for a sediment-hosted deposit in this region of Morocco. The
next steps are going to be determining the volume of material at the Fougnar
Project and if the material is amenable for commercial mining."

TEM survey

 

A High-Resolution TEM survey on a grid over the target area on the northern
permit and the southern permit of the Project has been processed with 593
Electro-Magnetic ("EM") Stations over 33 lines. The sample spacing on the
northern permit is 100m and on the southern permit is 250m. (Figure 2 left
side). Processed data with resistivity gridding successfully highlighted (see
Figure 2 right side):

·    The mapping of faults that control the mineralisation within the
sedimentary basin and fluid pathways and potential mineralisation traps.

·    On different slice depth managed to map out the plunge down dip of
the conductive zones with higher potential along strike within the basal
series siltstone that is known to host the mineralisation up to 500m deep.

 

Processed data 1D Cole-Cole and 2D interpolation of resistivity (industry
standard data modelling system) managed to demonstrate on sections (see Figure
3):

·    The top and bottom contact of the basal series siltstone that is
known to host the mineralisation (that is less resistive than formations on
the hanging wall and footwall and measure its dip along strike which is
critical to designing a systematic drill programme (optimal cost-effective
drill hole angles and target depths).

·    Potential zones of strong conductivity within the basal series and
their continuity down dip.

IP survey (Dipole-Dipole)

 

Induced Polarisation ("IP") surveys were conducted on 4km x 1km profiles
targeting conductive and chargeable sulphide rich horizons within the basal
series siltstone up to an approximative depth of 200m.

3 out 4 profiles were designed to cover known mineralised zones with Cu-Ag
historical channel sample intercepts and track down mineralised zones down dip
as proof of concept. IP results successfully demonstrate:

 

·    Mineralised horizons on outcrop show strong conductive and chargeable
anomalies from surface and their continuity down dip within the depth limit of
the method (≈ 200m) and delivered matured drill targets on 3 sections (red
arrows Figure 2 and left side Figure 4)

 

·    1 of 4 profiles targeted a detected conductive anomaly on TEM with an
IP effect at greater depth downdip within the basal series and highlighted
confirmed conductive anomaly with a chargeable anomaly that only starts 100m
from surface (red arrow with yellow stripes Figure 2 and right side of Figure
4).

JORC Code (2012) - Historical Exploration Results Disclaimer

 

The information in this announcement that relates to historical reported
exploration results is based on, and fairly represents, information and
supporting documentation prepared by previous operators and/or extracted from
historical reports.

 

The historical exploration results referred to in this announcement were
reported prior to the introduction of the JORC Code (2012) and have not been
reported in accordance with the JORC Code (2012).

 

A Competent Person has not done sufficient work to disclose the historical
exploration results in accordance with the JORC Code (2012). It is possible
that following further evaluation and/or exploration work, the accuracy and
reliability of the historical exploration results may not be confirmed.

 

The Company has not independently verified the historical exploration results,
and no assurance can be given that future exploration work will result in the
confirmation or upgrade of the historical results to JORC Code (2012)
compliant Mineral Resources or Ore Reserves.

 

The Company considers the historical exploration results to be relevant as
they provide an indication of the potential of the project. However, the
information should not be relied upon as a representation of the current
mineral resource or exploration potential.

 "Transient Electromagnetics ("TEM") surveys"  A geophysical technique used to obtain vertical resistivity soundings and is
                                               particularly effective for detecting conductive materials. It operates by
                                               inducing electric current flow within the subsurface and measuring the
                                               subsequent decay response of the magnetic field.
 "Induced Polarisation ("IP") surveys"         A geophysical imaging technique used to identify the electrical chargeability
                                               of subsurface materials. The process involves transmitting an electric current
                                               into the ground and measuring the voltage decay curve after the current is
                                               switched off, which indicates the material's capacity to retain charges over
                                               time.
