Electrum Discovery Corp. Releases 3D-inversion of Magnetic Data and Summer Fieldwork Plans for its Timok East Project, Serbia

(TheNewswire)

Electrum Discovery Corp.

Vancouver, Canada, July 2 2025 TheNewswire - Electrum Discovery Corp. (" Electrum " andor the " Company ") (TSX-V:ELY | FRA:R8N | OTC:ELDCF) is pleased to announce the results of 3D inversion modelling of ground magnetic data and to outline upcoming fieldwork plans at its Timok East Project ( " Timok East " andor the " Project " ) in eastern Serbia.

Highlights:

  • 3D inversion of ground magnetic data suggests continuity at depth to previously identified Western Mag, Limestone Contact, and Bambino Trend targets.

  • Recent field work 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 NNW- trending corridor of elevated magnetic susceptibility extends Bambino target over 7 kilometers

  • Along the contact between Jurassic limestone and Palaeozoic sediments, an ENE-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 underway to further test three primary targets.

"The 3D inversion results have provided an important new dimension to our geophysical understanding at Timok East," said Dr. Elena Clarici, CEO of Electrum Discovery Corp. "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 underway, we are moving to convert these compelling geophysical anomalies into well-constrained drilling targets."

Electrum has received results from 3D 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:

Bambino Trend

Along the Bambino Trend, the 3D inversion model highlights a prominent 7.5-kilometer NNW-trending corridor of elevated magnetic susceptibility extending from surface to depths exceeding 1 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 (Figure 1 & 2).

A soil sampling grid (~180 samples) is planned to test the northern portion of the corridor, where magnetic intensity is strongest, for signatures of underlying mineralization (Figure 1 & 3).

Western Mag Target

The Western Mag target is defined by a large, vertically continuous magnetic high along a major NNW-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 (Figure 1 & 2).

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 (Figure 3).

Limestone-Boundary Target

At the Limestone-Boundary target, an WNW-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 ( " CRD " ) mineralization.

The modelled anomaly dips west towards the Timok Magmatic Complex, displays moderate magnetic susceptibility and continuity to depths of approximately 850 metres, and may indicate localised magnetite enrichment potentially linked to unmapped intrusive dykes or to hydrothermally sourced magnetite enrichment (Figure 1 & 2).

A soil grid (~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 (Figure 3).

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 (e.g., CSAMT, HIRIP, or AMT) 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, i.e. the Bukova Glava permit, to delineate prospective intrusives and support ongoing field mapping and target definition.

Canada's Place in Global Mining: Why it's a Top Jurisdiction for Investors and Companies

For resource investors, geological potential is only one piece of the puzzle.

Whether it’s gold, silver, copper, nickel, uranium or any other commodity, the long-term success of a mining project is heavily dependent on jurisdiction. Mining is a capital-intensive, multi-year undertaking, and an asset's economics can be undermined by political instability, sudden regulatory changes or shifting government policies.

Canada stands out as a global leader in this regard. Its reputation as a stable and reliable mining jurisdiction is built on a foundation of political stability, the rule of law and a mature, transparent regulatory framework. This environment provides the certainty that investors require to commit the significant capital needed for exploration and development.

Australia as a Mining Jurisdiction: Assessing Risk in an Evolving Landscape

Australia has long been recognised as a stable and reliable jurisdiction for mining, a reputation built on its rich history in the sector. However, the industry is now coming to a crossroads.

The country's mining sector is facing a shifting regulatory landscape as it contends with trade tensions, wage equity reforms and increasing environmental, social and governance (ESG) demands.

These new pressures are reshaping everything from project development and investment decisions to environmental approvals and land access, forcing the sector — and investors — to navigate a complex and evolving landscape.

Navigating Uncertainty: How to Manage Jurisdictional Risk for Mining Stocks

In the high-stakes world of resource extraction, a nation's mineral wealth is a powerful magnet for investment, fueling economic growth and national prosperity. But not all countries are created equal.

For investors in the mining sector it's key to understand that jurisdictional risk can be profoundly impacted by political changes, as new administrations can swiftly alter the regulatory landscape. These policy shifts can present both opportunities and setbacks, introducing a complex layer of uncertainty to even the most promising ventures.

At the same time, regions traditionally seen as stable and secure for resource development can face their own challenges, including rigorous permitting regimes that can slow mine development activity.

Report: US$800 Billion in Mining Finance Could Derail Clean Energy Transition

A new report from the Forests & Finance Coalition warns that nearly US$800 billion in mining finance is accelerating extraction practices that could undermine global climate goals.

The study, titled "Mining and Money: Financial Faultlines in the Energy Transition," highlights what the organization calls “dangerously weak” safeguards in the sector.

Between 2016 and 2024, commercial banks extended US$493 billion in credit to companies mining copper, lithium, cobalt, nickel and other key transition minerals, according to the group.
