That’s fair, except I did read the page that I posted which contains details about the harvest site that only mentions the underground source and does not make any statements about the ocean.

Given the article above, and coupled with the knowledge that Mildura is definitely not near the ocean (in this millennium), it seemed reasonable to assert that that the salt was not derived from the ocean.

So yeah, I did read the link that I posted, but it did not mention that the salt deposits literally hundreds of kilometers inland originated from the ocean millions of years ago.

I withdraw my original statement, and hope you have a swell day. :)
