It must be a really rich gold mine essentially that part gets blasted out with each eruption. I'm not sure just an eruption alone would be hot enough to melt gold much in the period of time it's shot into the air, but it may do it enough to allow it to rain down gold dust? Interesting to speculate the mechanism, I just wish my backyard had that much gold!

I don't know man haven't you heard of pyroclastic flows? Apparently I have at some point in my life that I remember that term! 😃
