Sales of Australian bullion gold and silver advanced last month but were mixed compared to a year ago, new figures from the Perth Mint of Australia show. The increases came even as London bullion fixings marked May losses of 2.9% for gold and 1.5% for silver.

May sales of the Perth’s Australian gold coins and gold bars tallied to 36,127 ounces, which is up 54% from April but down 59.2% from May 2013. Sales of the Perth’s Australian silver coins and silver bars jumped to 630,349 ounces, surging 74.1% from the previous month and gaining 5.7% from a year ago. Conversely, demand in April for Perth Mint gold and silver bullion products dropped sharply from the previous month and from April 2013.
