Volcanic & Magmatic Gold Systems – Part 2: Volcanic Plumbing and the Path of Gold
Gold doesn’t float to the surface on its own—it moves along geologic highways hidden beneath extinct volcanoes. These are the plumbing systems that once fed eruptions, hot springs, and—most importantly—hydrothermal gold veins.
In this video, we dive into the internal architecture of a volcano to reveal how gold-rich fluids rise, where they stall, and what traps them into minable zones.

🧱 What is the Volcanic Plumbing System?
Think of a volcano like a multi-level structure. Beneath the visible cone lies a system of magmatic intrusions, ring faults, fractures, and conduit zones. As magma moves upward, it opens spaces and fractures that also allow superheated fluids to follow.
These fluids, released from cooling magma, are rich in metals—especially gold, silver, copper, arsenic, and tellurium.

🚿 How Fluids Travel and Drop Gold
Hydrothermal fluids move upward through:
• Dikes and radial fractures
• Ring fault systems around calderas
• Collapse zones from dome uplift
• Cross-cutting regional fault zones
When these fluids reach a critical drop in pressure or temperature, they boil rapidly, forcing dissolved metals to crystallize. This is how epithermal veins, stockwork zones, and breccia pipes are born.
In many systems, you’ll find concentric alteration halos and multiple overlapping vein stages. Early quartz often hosts pyrite, arsenopyrite, and base metals. Later pulses bring in visible gold or electrum.

🧭 Signs Prospectors Can Spot
Although these systems are hidden underground, they leave clues. Watch for:
• Fossil hot spring terraces or sinter deposits
• Rhyolite domes with radial quartz veins
• Breccia zones with limonite staining
• Clay caps or zones of intense argillic alteration
• Sheeted vein zones in volcaniclastics or andesite
These indicate the presence of a once-active hydrothermal system—and possibly gold remaining in situ.

🏗️ Real World Examples
Many modern mines trace old volcanic plumbing.
• At Cripple Creek, CO, gold came through narrow volcanic conduits.
• At Round Mountain, NV, layered pulses created low-angle veins.
• At Ladolam, PNG, boiling zones aligned with faulted caldera margins.
What these systems share is a controlled path for fluid flow—and clear evidence of episodic deposition over time.

🎯 Learn the Pattern
Once you understand how volcanic fluids rise and deposit metals, you can learn to predict where the gold horizon might lie. Whether you’re surface sampling, using a resistivity map, or hiking a fault zone—this knowledge gives you the edge.

In Part 3, we’ll bring it full circle—showing how erosion reveals ancient volcanic gold zones, and how to map them in the field.
