i used 560 as i know AXM is around these levels and should be pumping out 150k by this time next year then ramp up to 500k.
I thought 560 was pretty high given i know a few around 350.
Personally wouldn't touch anything above 600, and AXM even scared me a little when POG stopped for a while but i have faith in the management and their approach.
i have though taken your comments on board and will now look into MCO as it has been on my radar previously.
all in all i believe POG will be quite nicely positioned in the mid term and anyone in production will see the benefits.
