CUBE, can you read Russian? Or have you found the story in English somewhere? If so, I would enjoy a link.
"машину ушло всего 18 кг золота"
Might that say something about 18 karat? Where's the 40 pounds, arggg, I can't read it.

Well, based on your figures, the scrap gold would be worth ...
584 ounces X $829.90/ounce = $484,661.60
If it's "only" 18 karat, that would be $363,496.20 in scrap value alone. It is quite the spectacle in any case!
