Thieves might have smuggled mint gold in acid
OTTAWA -- Was $15-million worth of gold stolen from the Royal Canadian Mint by dissolving it in acid, rendering it invisible to metal detectors?
Two gold-refining industry sources say gold chloride dissolved in an acid solution can be unrecognizable to metal detectors, such as those guarding the mint's high-security Sussex Drive refinery in Ottawa -- and the method might explain the recently announced disappearance of more than half a metric ton of gold from the mint's inventory.
"It could be taken out in that form . . . in a liquid chemical form," one U.S. refining executive said.
A similar method was used to hide two Nobel laureates' gold medals from the Nazis when Germany occupied Denmark in 1940.
