Claim 1: “prices for the metal [copper] were highly volatile but holding at historically elevated levels around $13,500 a ton.”

SINGLE SOURCE

One source (Crux Investor) mentions copper prices above US$12,000 and falling below US$13,400, which is in the general vicinity of $13,500, but there is no corroboration of the specific 'historically elevated levels around $13,500' phrasing across multiple sources.
