Ann: Updated Exploration target for the Never Never Gold Deposit, page-126

I would look to see if there are other shoots in similar geological settings around the world that have joined up at mineable depths of say less than 4km , SL has not compared NN to any that have from what I have read .
Therefore hard for me to be swayed by his theory , unless he shows some seismic/gravity or IP modeling to to support his theory .


Given SL has taken the liberty to express his conjecture I will also express my less knowledgeable opinion :
Rather than joining up at a mineable depth , More likely NN goes down 2 to 3 kms , in the same way it has for the last 700 meter or s , by following a rock fracture, with continuation of the mineralisation having been deposited between a deep fracture as in the normal hydrothermal modal , and hopefully the mesothermal rather than epithermal style(smoker) of that to get depth .
WW and SLYfox could well go deep to , but is the OVM and grade there for them each to cover mine development ?
I am assuming similar pressures and temperatures needed to deposit mineralisation and the same mineralisation deposited going down another 2300 meters which is drawing a long bow .

As to method of mining , I still do not understand why some on here are referencing 30 M wide stopes that SL supposedly mentioned in a presentation , as the true width drill intercepts look around half of that at the max say 15 meters .
So why do they need to drill 6 parallel headings like you showed in your example when they could just drill one 15M wide drive or if too wide an arch, then two drives with pillar support (or paste support) between the two
Then do vertical long hole drilling/blasting in the panels between the lower drive and the offset drive (due to the subvertical ore body ) say 16 meters above and stope out by retreating back to the decline ?

Would not that seem more methodical than sub level caving that is going to result in likely more dilution due to poor control over overbreak causing extra dilution ?

Others on here with actual UG mining experience may offer their more knowledgeable opinion , as I am likely to have it all wrong and I would like to know the true answer on why 30M stopes needed !
