ADN Site Visit Confirms Major Upside Potential, page-58

I would hope we will be utilising a haul back mining method. That is - remove first section (pit) and place overburden (10m seam) in stockpile, remove mineral (20m deep seam), then move to the next pit that is parallel to the first and place the overburden into the pit one void. This will not only allow us to progressively undertake rehabilitation, minimise the mine footprint and subsequent statutory government security required ($$$$ security based on the rehabilitation cost estimate), but also avoid the costly exercise of double handling overburden

hope this helps
