It sounds like he actually means MICROminerals (as opposed to the MACROminerals of e.g. calcium, magnesium, potassium) when he writes 'sub-atomic minerals'.
Sounds like he also doesn't have a grasp of what "sub-atomic" even means. But what the heck would we know, given that we're the "wise of the world" and he's "simple in the LORD" (his own words).
