There was or is a series on YouTube by Cody'sLab, where person was exploiting approx. two meters of rock in an abandoned mine in Utah, USA, to make at most some kilograms of refined metals, while being exposed to radioactive and toxic materials in the process (person is or was a geologist and chemist, so knew what to look out for).

I wonder if that would be called a voluntary mine.
