Teako outlines three new VMS targets at Venna

Executive Summary

• Teako Minerals Corp. has released laboratory results from 61 rock chip samples taken during its 2025 sampling program at the Mostadmarka target area of its 100%-owned Venna project in Norway.
• The geochemical data has led to the identification of three high-priority VMS targets: Navra, Heingruva, and Storslatten, indicating potential for buried massive sulphide mineralization associated with high-temperature VMS-fertile fluids.
• The study characterized host volcanic rocks and confirmed hydrothermal origins for sulphide occurrences, with specific geochemical signatures suggesting hydrothermal replacement at Navra and proximal hot hydrothermal vent sources at Heingruva.

Key Details

• Sampling Program: 61 rock chip samples analyzed from the Mostadmarka target area.
• Identified Targets: Three high-priority VMS targets identified for follow-up:
  • Navra: Located in the ironworks trend (~10 km strike extent). Identified by a cluster of sulphide and trace element enriched samples over ~1.2 km.
  • Heingruva: Located in the ironworks trend. Highlighted by four samples showing hydrothermal exhalative composition, including two with indicators of a proximal hot hydrothermal vent source.
  • Storslatten: Located in the southern magnetic trend. Contains geochemical and textural indicators of hydrothermal stringer veins along strike of a geophysical (airborne electromagnetic) anomaly stretching ~2.2 km.
• Navra Target Geochemistry:
  • 11 samples over ~1.2 km strike show elevated sulphur (up to 2.62%), base metals (up to 305 ppm Cu+Pb+Zn), and pathfinder elements (up to 59 ppm As, 6.16 ppm Sb).
  • Notable Al2O3 content (average 2.59%) suggests formation via hydrothermal replacement rather than exhalative processes, which can favor higher-grade and larger tonnage deposits.
• Heingruva Target Geochemistry:
  • Lower Al2O3 content (average 0.51%) indicates pure hydrothermal exhalative lithology.
  • Two samples show prospective positive Eu anomalies, indicating hot hydrothermal fluids venting at the paleo-seafloor.
• Storslatten Target Geochemistry:
  • Two samples from the FDEM target and two samples ~4 km SW show elevated As, Sb, Ag, Mo, Tl, and K.
  • Elevated pXRF SiO2 values (proxy for quartz veining) and lower light REE concentrations indicate a hydrothermal origin.
  • Interpreted as concealed sulphide mineralization due to the absence of graphitic schists on regional maps.
• Sandsve Occurrence:
  • Previously identified high-grade Cu occurrence (Sandsve-2 at 2.5% Cu) is situated west and along strike of Storslatten, suggesting a potential connection to buried massive sulphide mineralization.
• Host Rock Characterization:
  • Ironworks trend hosted by basaltic- to basaltic-andesite lavas and volcaniclastics from an enriched mantle source (upper Mostadmarka formation).
  • Southern magnetic trend hosted by mid-ocean ridge basalt (MORB) volcanic rocks (lower Mostadmarka formation).
• Next Steps:
  • Comparison with geochemical signatures of known VMS deposits (e.g., historical Lokken mine).
  • Additional higher-resolution geochemical sampling and high-resolution surveys anticipated to refine drill targets.
• QA/QC:
  • Samples submitted to ALS Laboratories in Pitea, Sweden.
  • Analyzed via ICP-MS and -AES techniques (ALS codes ME-MS61r, ME-ICP06, ME-MS81, ME-MS42, ME-4ACD81) plus loss on ignition.
  • ALS Laboratories is ISO 9001:2015 and ISO/IEC 17025:2017 accredited.
