You got me thinking more about these breccia pipes and potential system below.
The thing about breccia pipes is they act like geological chimneys. When deep-seated heat and pressure build up, they force mineral-rich fluids upward through narrow pathways — kind of like how a volcano vents gases before an eruption. The hotter and more violent the system, the more those fluids can dissolve and transport metals like rare earths and gold.
As those fluids rise and cool, they start dropping out their load. Minerals start crystallizing and coating the walls of the pipe — especially in zones where the fluid slows down or hits a temperature/pressure drop. Over time, these “chimneys” get lined with the good stuff — REEs, gold, and more.
So if Colosseum’s pipes are that type — with multiple fluid pulses, chaotic brecciation, and signs of intense heat — then we might be looking at conduits straight from the engine room of the whole system.
