The last section of the article is even more mind blowing, Reputation & Trust:

1. The mint was forced to adopt a "corrective action plan" after PNG gold was revealed to have been cut with mercury and mined with the help of child labour.

2. The other headache for the mint is an ongoing investigation by financial crime regulator, AUSTRAC, into its compliance with Australia's anti-money-laundering laws.

Oh and in the same week as this crisis was unfolding behind closed doors at the Perth Mint, it was announced that Mr Hayes would be retiring early due to illness.

Mr Hayes should probably be behind bars and not gold ones!
