Avaron Announces results from geophysical survey at Tolisnica property, Serbia
June 16, 2025 – Vancouver, British Columbia (TSX-V: AVR) Avaron Mining Corp. (the “Company” or
“Avaron”) is pleased to announce the successful completion of a geophysical survey and data
interpretation program on the Tolisnica exploration license, located in central Serbia, approximately 40
km southwest of the town of Kraljevo. The survey aimed to define high -potential copper -cobalt
mineralization associated with altered mafic -ultramafic rocks within the historically productive Vardar
Zone.
This recent work represents a significant step forward in Avaron’s systematic exploration strategy and lays
the foundation for delineating drill-ready targets on the Company’s flagship project.
Geophysical Survey Overview
Conducted in May 2025 by GEO -IN INTERNATIONAL D.O.O., the geophysical campaign utilized Electrical
Resistivity Tomography (ERT) profiling across 15 lines totaling 3,525 meters. Data acquisition was
performed using a state -of-the-art MAE X612EM48+ multi -channel resistivity system, configured with a
VES-type array to optimize detection of subsurface conductive and resistive zones at depths relevant to
near-surface and intermediate mineral systems.
The survey successfully imaged multiple zones of anomalous resistivity interpreted as sulfide -rich zones
and structurally controlled mineralized corridors. Data processing using ZondRes2D and Surfer software
generated six integrated 2D models across the To lisnica property. Interpretation focused on identifying
structural traps, lithological contrasts, and geoelectrical signatures consistent with known styles of
copper-cobalt-silver mineralization observed in prior mapping and historical drilling.
Survey Highlights
• Fifteen ERT profiles completed over four days, covering varied terrain with elevations ranging
from ~700 m to 760 m above sea level.
• Presence of subparallel resistivity lows interpreted as alteration zones or structural corridors.
• Consistency between interpreted anomalies and historical copper- cobalt mineralization in
brecciated diabase and gabbro units.
• Several targets exhibit specific electrical resistivity (SER) values <100 Ω·m, indicative of potential
hydrothermal alteration and/or sulfide mineralization.
• Discrete resistivity highs (>1,000 Ω·m) may represent unaltered, competent host rocks.
Next Steps
Avaron will integrate the ERT data with historical diamond drilling (15 holes totaling 2,325.1 meters),
ground magnetics, and 2018 –2021 rock chip assay results. This comprehensive geological model will
support the design of a maiden drill program, anticipated in 2026. The Company plans to test both near-
surface and down-dip extensions of copper-cobalt mineralization within brecciated diabase and gabbro,
where historical results include intervals of up to 1.1% Cu over 6 meters and surface rock samples
exceeding 5,500 ppm Cu and 1,500 ppm Co (BenzCapTechRpt.pdf and Geophysics _Tolišnica 2025 -
