Several correction -- the symbol is IMT.V, not ITM.v, and the mineral at Serpent River is uranium, not nickel.
You are correct that nickel has been the best performing major metal this year, though zinc and lead haven't been far behind.
Since my favourite nickel miner, Western Areas, is no longer listed in Canada, I am playing the nickel bull with warrants on RNX.TO. But be aware that if Indonesia backs off on their export restrictions, nickel could crash suddenly. Zinc is still the better play IMO -- I have shares in TV.TO, ZNC.TO, and SWN.V
