ELECTRUM DISCOVERY CORP. RELEASES 3D-INVERSION OF MAGNETIC DATA AND SUMMER FIELDWORK PLANS FOR ITS TIMOK EAST PROJECT, SERBIA

Electrum Discovery Corp. has released the results of 3-D inversion modelling of ground magnetic data and to outline coming fieldwork plans at its Timok East project in eastern Serbia.

Highlights:

• The 3-D inversion of ground magnetic data suggests continuity at depth to the previously identified Western Mag, limestone contact and Bambino trend targets.
• Recent fieldwork discovered the outcropping of phase 1 andesitic volcanics at the Western Mag target, a geological unit known to host copper-gold systems in the Timok region.
• A prominent north-northwest-trending corridor of elevated magnetic susceptibility extends Bambino target over seven kilometres.
• Along the contact between Jurassic limestone and Palaeozoic sediments, an east-northeast-trending magnetic anomaly is being selected for further work as a target prospective for skarn and carbonate replacement mineralization.
• Follow-up mapping and soil sampling are under way to further test three primary targets.

"The 3-D inversion results have provided an important new dimension to our geophysical understanding at Timok East," said Dr. Elena Clarici, chief executive officer of Electrum Discovery. "The continuity of magnetic features with depth and particularly along the Bambino trend and Western Mag target enhances their significance. With our soil sampling and geological mapping programs now under way, we are moving to convert these compelling geophysical anomalies into well-constrained drilling targets."

Electrum has received results from 3-D inversion modelling of its high-resolution ground magnetic survey at Timok East. Modelling was carried out by Terra Scout Ltd. (Sofia, Bulgaria) an experienced provider of ground magnetic data acquisition and modelling.

The model suggests multiple vertically extensive magnetic zones with elevated magnetic susceptibility values potentially caused by magnetite-bearing intrusions or skarn-style alteration. Key observations at each target include the following.

Bambino trend

Along the Bambino trend, the 3-D inversion model highlights a prominent 7.5-kilometre, north-northwest-trending corridor of elevated magnetic susceptibility extending from surface to depths exceeding one kilometre. This anomaly coincides with copper, gold and silver anomalies in surface rock-chip samples and copper-in-soil anomalism at both the Bambino prospect and the Northern Skarn target.

A soil sampling grid (approximately 180 samples) is planned to test the northern portion of the corridor, where magnetic intensity is strongest, for signatures of underlying mineralization.

Western Mag target

The Western Mag target is defined by a large, vertically continuous magnetic high along a major north-northwest-trending structural corridor. Fieldwork has confirmed the anomaly is spatially associated with outcrops of phase 1 andesitic volcanics, a lithology well known to host copper-gold systems elsewhere in the Timok region.

The anomaly extends south beneath Neogene cover, indicating potential for concealed targets.

Analysis results are awaited for a soil grid of 225 samples that has been collected to assess geochemical indicators for porphyry-style mineralization at the Western Mag target.

Limestone boundary target

At the limestone boundary target, a west-northwest-trending magnetic anomaly has been identified along the boundary between non-magnetic to weakly magnetic Jurassic limestone and Palaeozoic sediments. This boundary is considered prospective for skarn and carbonate replacement deposit (CRD) mineralization.

The modelled anomaly dips west toward the Timok magmatic complex, displays moderate magnetic susceptibility and continuity to depths of approximately 850 metres, and may indicate localized magnetite enrichment potentially linked to unmapped intrusive dikes or to hydrothermally sourced magnetite enrichment.

A soil grid (approximately 140 samples), along with scout geological mapping, is planned to investigate the cause of the magnetic anomaly and identify geochemical signatures that may indicate the presence of hydrothermal mineralization associated with this boundary.

Summer 2025 exploration plan:

• Soil sampling, field mapping and prospecting across defined target areas to identify geochemical anomalies and identify geochemical signatures that may indicate underlying mineralization;
• Deeper geophysical surveys (for example, CSAMT (controlled-source audio-frequency magnetotellurics), HIRIP (high-resolution induced polarization) or AMT (audio-frequency magnetotellurics)) over soil-defined targets to generate resistivity models of the subsurface to guide drill targeting;
• Ground magnetic survey at the northern part of the Timok East project (that is, the Bukova Glava permit) to delineate prospective intrusives and support continuing field mapping and target definition.
