Don't be ridiculous. The video narrator specifies that the gold on the basalt must have been present locally at the eruption, but as anyone can tell you who has read the Silmarillion seventeen times and memorized every single historical fact therein (while being unable to, for example, name their legislative representatives), Mount Doom is canonically in New Zealand, thus the gold in Iceland can't be from the One Ring. I give this post a 1/10, it would be a 0/10 but Jeff Bezos is censoring me.
