The 10 year gold oil ratio looks a tad ominous. Even if you don't really think this ratio has any long term viability perhaps it might be prudent to just keep away from any gold investment bar a short.
The last time (2008) that Brent Crude reached these lows, gold fell to $700/ounce. Goldies might look cheap now but at AUD$1,000 (US$700) present prices would look very expensive.
