TomaGold Launches Deep Geophysical Survey at Berrigan Mine
Event summary
- TomaGold begins audio-frequency magnetotelluric (AMT) survey at Berrigan Mine project in Québec's Chibougamau Mining Camp
- Survey aims to map deep structural features and conductive bodies associated with polymetallic mineralization up to 2 km depth
- 14-line grid covering 7.5 line-kilometres with measurement stations every 25 metres
- Assay results from Phase 2 drilling program still pending
The big picture
TomaGold's systematic exploration strategy reflects the growing industry trend of using advanced geophysical techniques to unlock deeper, structurally controlled mineralization. The focus on district-scale understanding aligns with recent successes in identifying concealed massive sulphide targets at depth, potentially expanding the economic potential of Québec's mature mining camps.
What we're watching
- Exploration Results
- Whether the AMT survey identifies new high-priority targets that could expand Berrigan's resource base
- Drill Targeting
- How the 3D structural understanding will optimize future drill programs across TomaGold's Chibougamau portfolio
- Resource Validation
- The pace at which historical estimates can be updated to NI 43-101 standards following additional drilling and resampling
