I believe an under-appreciated risk are levels of resource confidence. Relatively little ore is drilled to measured status (see table) and has tended to focus on resource volume expansion rather than improving confidence

I acknowledge extending mine life is a prerequisite to exciting the market and securing institutional support, but there are risks involved in the current approach. Unexpected downward resource estimate revisions following commencement of mining could be diabolical for share price and even jeopardise the basis of the operation.
