I've been on BRN for a long time and they trade over the counter in the USA (may be different to what IHL will do).

The USA exchange never seems to effect the ASX price as it generally moves to what happens in ASX first and the volume in the US exchange is always much less.

You can see by the charts as an example they're practically identical.

IHL may be a different story due to the interest in Northern America and this BOD are all over it they haven't put a foot wrong yet.
