Positive Stream Sediment Sampling Results Identify Multiple Priority Targets
at Fougnar, Morocco

 

Dublin, Ireland - Talisman Metals PLC ("Talisman" or the "Company") reports
the results of its recently completed stream sediment sampling program (see
press release 24 February 2026) at the Company's Fougnar licenses ("Fougnar
Project"), which are 25km west of the Tizert copper-silver mine, see Figure 1.

 

The stream sediment work, in combination with historical field work and
mapping, confirms the priority of established drill targets (see press release
of 16 April 2026). Additionally, a previously unknown area of potential
mineralisation has been discovered and will be added to the anticipated drill
program scheduled for the summer 2026, see Figure 2.  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 main work focus at the Fougnar
Project to date has been on the northern section, due to outcropping
mineralisation. However, significantly copper-anomalous samples were collected
on the southern part of the Fougnar Project over a 1km long interval. We now
have expanded the target zone to an even larger area to drill."

 

Highlights

 

·    A total of 132 stream sediment samples were collected across the
Fougnar Project;

 

·    Multiple anomalous catchments were identified, with assay results of
up to:

200 ppm Cu (Copper), 6,510 ppm Ba (Barium), 502 ppm Pb (Lead), 161 ppm Zn
(Zinc)

 

·    Newly identified target corridors extend over approximately 4 km
across six distinct target areas (see Figure 2), in addition to the existing
2.5 km mineralised trend identified along strike;

 

·    Historical trenching areas containing known mineralisation were
successfully confirmed by stream sediment sampling and used as orientation
areas to establish threshold values for copper geochemical anomalies;

 

·    Several geochemical anomalies are spatially associated with mapped
structural features identified in the field and interpreted from ground TEM
surveys and favourable lithological units within the basal series stratigraphy
(see Figure 2).

 

Methodology and QAQC

 

Stream sediment samples were collected from fine sediment traps within active
drainage channels over intervals of approximately 20-30 m along stream
courses, while avoiding areas affected by anthropogenic contamination or
stream disturbance (including terraces). Sample locations were recorded using
handheld GPS devices.

 

Samples were dried and sieved to <63 μm (one millionth of a meter) prior
to analysis. A total of 23 QA/QC samples were inserted into the sample stream,
comprising approximately 5% blanks, 5% field duplicates, and 5% certified
reference materials ("CRMs").

 

Samples were submitted to the ONHYM laboratory in Rabat, Morocco for
multi-element analysis using a three-acid digestion (HCl-HNO₃-HF) with
ICP-AES finish. The analytical method has a lower detection limit of 5 ppm for
copper (Cu) and 1 ppm for silver (Ag).

 

Blank samples showed no evidence of contamination above three times the
detection limit for Cu or Ag. Field duplicates demonstrated excellent
repeatability, with an R² value of 0.99. Certified reference materials
consistently returned copper values approximately 10-20% below certified
values, and the Company is reviewing the potential analytical bias; however,
the Company does not currently consider this issue to materially impact the
interpretation of the results.

 

Follow-up work programmes underway including:

 

·    Detailed geological mapping and rock-chip sampling;

·    Trenching across priority target areas;

·    Follow-up drilling of any significant trench results to test
mineralisation at depth and along strike.
