Yes it is a little unusual. Possibly driven by RIO's announcement on the 7th
See loulouhaha and fishoMC's post on the "breakout" thread. This is from RIO's announcement.
Perhaps people read that announcement and picked up some CFEO just in case
"Rio Tinto reports three billion tonnes of additional Resources 7 February 2008 Rio Tinto has further strengthened its leading position in the Pilbara with a 3.0 billion tonne addition to its iron ore Resource base. This came through the discovery of a major new Resource at Caliwingina, and significant improvement in confidence of resources associated with known deposits. The Chief Executive of Rio Tinto Iron Ore, Sam Walsh, said significant technical and study work has led to increased confidence in Rio Tinto’s position in the Pilbara. “Rio Tinto occupies the largest mineralisation and land position in the Pilbara, one of the world’s great iron ore producing regions. This advantage is strengthened by addition of the newly discovered Resource at Caliwingina, comprising 875 million tonnes of iron ore only 15 kilometres from our railway and only 150 km from our ports at Dampier and Cape Lambert, as well as significant additions around known deposits.”"
