I too just spoke to the company, and they assured me that there was no bad news, everything is going well.
Just doing a quick glance at other small and mid cap mining and engineering companies listited on the asx and lot of them got belted today, ie MAH, Cardo, Bradken, AAX.
Worley Parsons and WDS got belted yesterday, so I guess it was NMS turn, might be good buying.......
