I think the stellar run up in the price of Copper, & gold has been responsible for this moreso? Copper has gone up somewhere near 20% in a few weeks... from 3.1-3.2 to nearly 4; which has majorly boosted sentiment.
Copper on 12th Feb 3.55/lb, now 3.86/lb. Up 8.7%.
Gold US$917 on 12 th FEB, now US980. Up 6.7%
OXR on 12th Feb 3.13, yesterday 3.97. Up 26.8%
Doesn't stand up.
