# Liberty Star announces successful IP/resistivity test at Red Rock Canyon Gold Project

## Summary
- July 2025 geophysical test detects and maps gold-bearing veins via IP and resistivity.
- Gold veins show higher resistivity due to siliceous jasperoidal character, visible under soil cover.
- Higher IP values confirm sulfide mineralization (pyrite, arsenopyrite) typical of Carlin-style deposits.
- CTO Dr. Jim Fink calls results 'most positive IP survey in my entire career.'
- Chairman Pete O'Heeron says data validated approach and will optimize drilling targets.
