Ann: Gwalia Mass Extraction Feasibility Study, Guidance & webcast, page-166

Hey @eshmun, long time fan and appreciate your input.

As you state I am not in the market to scare monger as complications at depth are very common but I would say that investors should be aware of the potential increased risk. Sometimes I see a disconnect between the investors and the actual mining process, at the end of the day without good stable access the ore can not be extracted.

I am unsure if people have a broader view of the market but Newcrest had large delays at Cadia due to geotechnical issues last year:
'The eartquake damage forced the mine to close down from April to June 2017 and resulted in a year-over-year slump of 48 per cent to the miner’s half-year (HY) statutory profit of $98 million.'

Im not saying it will happen and heaven forbid it does, I am just stating that if it does there isnt much left in the back catalog at SBM as another ore source, therefore making it overpriced IMO.

The tree details for stopes I have also heard of in Kambalda but now PAF backfill would be used. At Gwalia this is taken from the surface fixed plant and pumped underground via a service line to the required stoping area. This may have changed with the recent upgrades.
