Mines Regulations and Metalliferous Mines Regulation Acts. Many areas, mainly on Grand Terre have some very high concentrations of metalliferous rocks. Note that the King of the Golden River was imprisoned through "metalliferous undertakings". A typical source of such aggregates is metalliferous mine waste. When actively being inhabited, the surface of the burrow is made of red metalliferous sediment. The mineral occurs in metalliferous veins with calcite, argentiferous galena, native silver, native arsenic, &c.
