Out of interest I made this chart for further purpose.
left hand: XAGUSD 5y chart (Silver)
right hand: XAUUSD 5y chart (Gold)
Silver has a nice rendezvous in June 2015 - interesting to watch for.
HOWEVER
As gold is the driver, it could be a non-event tho'. Indeed XAUUSD has not this kind of convergences on the chart.
