Talisman Metals PLC announced an exploration update as of 13 March 2026 on its preliminary programme at its Fougnar Copper-Silver Project. The update notes the successful completion of the Company's stream sediment sampling work, and the 76% completion of its Ground Transient Electromagnetics planned grid. Additionally, two trenches were dug which have visible copper mineralization (malachite) shows within the channel sampling.
The Company is in the process of finishing a modest reverse circulation scout drilling programme that includes two drillholes on each of the two licenses of the Project. Ground geophysics: TEM surveys: a High-Resolution TEM survey on a 250m × 100m grid over target area on the northern permit of the Project is now complete (416 Electro-Magnetic Stations). Pre-processed data highlighted a zone that shows strong conductivity and appears partially continuous, slightly folded, with offsets that could be interpreted as normal controlling a horst and graben system (topography consisting of alternating raised and lowered fault blocks).
Inversion will be done on 1D Cole-Cole and 2D interpolation. This work will be done to map out structures that control mineralisation and resistive profiles to track conductive horizons up to 500m deep. A lower resolution 250m × 250m grid over the target area of the Project's southern permit has commenced, with 18 out of 153 planned EM Stations completed.
Induced Polarisation surveys: Based on the results from the TEM sections, Four-pole dipole-dipole IP surveys of 1km profiles across priority targets in the Project northern permit area will be surveyed to track mineralised/conductive and chargeable sulphide rich horizons up to 300m deep. Regional surface geochemistry: Stream sediment sampling to extend geochemical coverage and identify additional Cu-Ag and pathfinder anomalies across catchments on the west part of the Project has been completed with 154 Samples including 7 CRMs, 7 Blanks, 8 Field Duplicates. Follow-up sampling of known best surface intercepts at depth and along strike: Two trenches have been completed on the northern permit to expose bedrock beneath downslope material in order to measure Cu-Ag grade and thickness along strike.
Systematic channel sampling has commenced as well. This work aims to define the controls on mineralisation continuity and to improve understanding of the structural components within the host sedimentary units and mineralisation thickness prior to conducting systematic drilling. The drilling of two scout RC drill holes has begun on site to test geological stratigraphy associated with mapped data and outcropping Cu-Ag down dip from previous trench results (FO-CH09 with 1.1m @ 1.16% Cu and 53g/t Au, FO-CH02 with 0.6m @ 0.41% Cu and FO-CH04 0.7m @ 0.70% Cu and 17g/t Au).
The current programme is designed to test both strike and depth continuity of mineralised Cu-Ag zones and to assess the broader prospectivity of the Project area. Results from trenching, geophysics, and geochemical sampling will be used to refine drill targets, with further updates to be provided as data become available.
