Fault Gouge Gold – From Crushed Rock to High-Grade Payzones (Full Guide)
Description:
Gold often travels through the earth’s fractures, but it rarely deposits where most people look. In this full-length video class, we explore one of the most powerful—but underexplored—zones in hard rock prospecting: fault gouge.
Fault gouge is the soft, crushed clay-like rock that forms during tectonic movement. When faults grind together, the rock between them turns into a mix of broken minerals, clays, and oxidized particles. It may not look like much—but this material holds the key to some of the richest ore shoot formation in fault-hosted gold systems.
In this 8:45 educational deep dive, you’ll learn:
• What fault gouge is and how it forms
• Why its physical and chemical properties trap gold
• How crushed quartz veins inside gouge act as feeder systems
• The meaning of limonite, manganese staining, and clay alteration
• How fault gouge evolves into high-grade ore shoots
• What field sampling methods to use near gouge-vein interfaces
• How to use AI Gold Maps to identify gouge zones remotely
These aren’t just theory-based lessons—they’re boots-on-the-ground techniques used by serious prospectors in the U.S. Southwest, Nevada trend, Mother Lode belt, and beyond. This class is built for gold hunters who want to understand the geology behind their next big find.
Key Concepts:
• Gouge acts as a fluid trap: Reduced permeability, pressure drops, and reactive clays combine to create perfect precipitation conditions.
• Alteration is a roadmap: Oxidized halos, black coatings, and sudden color changes mark gold-bearing zones.
• Ore shoots follow gouge transitions: Where soft gouge meets hard rock, or where fluid pathways widen, enrichment occurs.
By the end of this class, you’ll be able to identify gouge zones, follow them to their mineralized edges, and recognize the clues that point to concentrated gold zones most people walk right past.
