re: Ann: High Grade Manganese from Waddikee P... This is encouraging. The grades are OK - but highly dependent on how good a product they can produce via beneficiation.

The colour of the AC piles looks OK, these guys should be able to do some chip test work to give an indication.

The style of mineralisation looks structural based on that drilling section. This is Ok in an exploration sense - they can use EM anomalism to generate followup targets and to map the extents of this mineralisation. EM is relatively cheap considering the coverage it can provide, but it is also highly effective in defining these "pods". Note, the explorers around Woodie Woodie in WA are called "pod chasers", and they rely on EM to define their pods.

The only real question is - does the style of mineralisation result in a lump product after beneficiation? That is, is the Mn mineralisation discrete from the waste, or is there layers of waste/gangue that will require crushing to seperate?

Cutoff grade is therefore determined by the Mn itself. You can have a cutoff as low as 10%, or as high as 30%. It really depends on how easy/hard to generate +40% Mn product, and therefore the costs involved to achive that product. So the moral is, take each Mn deposit on its own merits and wait until benefication testwork before deciding on the cutoff.
