Episode notes
Tolita Anomaly Is Larger And Deeper
- Tolita's IP anomaly is large and remains open both at depth and to the north, suggesting greater potential than initially mapped.
- Deeper drilling (up to ~1,200 m) is planned because previous 600 m holes finished in mineralization and began showing silver near the tips.
Correlation Boosts IP Reliability
- IP surveys gain predictive value as you correlate drill results with geophysical signatures over time.
- Using an experienced IP firm that worked on major Chilean assets improves interpretation confidence for Tolita.
Last Season's Holes Ended In Mineralization
- The two 600 m diamond holes last season both finished in mineralization and showed silver in the last 20–30 m.
- That observation prompted plans to drill deeper with rigs capable of ~1,100–1,200 m holes.
