Aug 10, 2025 (The Australian Financial Review - ABIX via COMTEX) -- A spokeswoman for the Perth Mint has acknowledged concerns have been expressed about how some of its customers may be using a product known as gold chloroauric acid, which can be converted into gold. The Mint has been exporting regular shipments of gold chloroauric acid to India on behalf of a company called Hindustan Platinum, with gold chloroauric acid attracting a lower tariff than gold.
