Yeah, I sell mining equipment and so that was my first reaction...cheaper to use heavy equipment. Maybe they’re re-working tailings.

OTOH, if this is a way for them to make a living and survive, who are we to tell them they can’t.

But, when in doubt, use a bulldozer.

The video I put up gave a hint on what was taking place when they sold the Cobalt.
She said, "The buyer didn't ask questions how he got the Cobalt"

In other words they were working as entrepreneurs and would had to have changed as soon as the owner realized a bulldozer was cheaper and he could afford to buy one.
