Rusteze it's all about technology and obviously these guys found a better way to increase recovery rates and more recoverable "nickel pounds" I liked the following snippets and thought about what may be looked at as lower grade halos that may abound in our regions.

"Garett Macdonald, Canadian Arrow's VP of Operations noted "We are very pleased with the results of the metallurgical program. The recent flotation results show that the Kenbridge project can deliver excellent metal recoveries and a saleable concentrate product with a simple & proven process from relatively low grade material. The results indicate that more saleable nickel pounds can be recovered with insignificant change to operating costs or effort as evaluated in the January 2008 PEA."

Mr. Macdonald adds, "This strong metallurgical response is what makes Kenbridge stand out. It is important to note that although higher grade zones occur within the Kenbridge deposit, the robust metallurgical recoveries allow for efficient and economic extraction of the lower grade halo as well, thus providing full value optimization."

Of course as you mentioned Xstrata and Micon are involved as well

"The metallurgical program was completed by Xstrata Process Support (XPS) in Sudbury, Ontario under the direction of XPS metallurgists David Middleditch and Dominic Fragomeni. Richard Gowans, senior metallurgist and Vice President of Micon International, advised the company on the program and is the independent qualified person (QP). "
