Old timers sank these vertical shafts and walked away — leaving MASSIVE pocket gold behind. As a geologist with 40+ years in the field, I can tell you exactly WHY they left, and more importantly, how YOU can recognize the same geological signs today.
In this video, I take you deep into a 100-year-old vertical mine shaft to show you the exact geological patterns that created pocket gold — and why most prospectors walk right past it.
What you'll learn:
The role of rhyolitic domes and fault breccia in trapping pocket gold
How to identify goethite and iron staining as gold indicators
Why strike-slip fault zones concentrate gold in "lenses"
The difference between fault gouge and productive mineralization
How to channel sample and process material from hard rock workings
Why dish soap improves fine gold recovery in the pan
