Is this resource under water?, page-217

This was the first pic I found of the mine that made me wonder as Ive seen tailing dam retention walls and their bases are huge much like a pyramid.
This wall doesnt offer this. Its pretty sheer face.
The ocean is deep sea too as we can see from a ship. How deep?

Fjords can be very deep indeed. Deeper that youd realize. Heres a local one that goes from 500 to 1.5 km deep.

The longest of the fjords extends 340–350 km (210-216 mi) inland from the coastline.[1] The depth is 400–600 m (1,310-1,970 ft) in the main basin, but depths increase to up to 1,450 m (4,760 ft) in some fjords.[1] It is one of the largest and longest fjord systems in the world.[3][4][5]

So that entire wall could easily be part ocean pressing against it. Have you actually ever seen anything like that holding back the sea?

This isnt really something to snuff at surely. That entire wall depth could be holding back water and its just natural rock at most at a point, two road widths wide.. Not a reinforced man made pyramid shaped dam.

As Id first suggested
1) how much more mining could undermine it and
2) is it porous and offering egress for the water we see getting into it
3) Treatment once its subjected to mining exposure
Why raise this?

If this water is from where sea water is seeping. There may well be an issue.
You surely cant go open cut anymore as the wall may well go. But yet this is where the quartz lays.
If the mine was filled so to support the wall then again is this question not ok to ask?

The slae price on this tenement to me seems to be focused on the potential worth of the quartz. Have you seen how much is getting paid for this mine? Its a lot of capital when you add up progress payments. You dont wish for issue after its been sold.
Maybe Im just curious and maybe theres nothing there. But I do know Greenland and I know how intense they can be over environmental issues and in so I just have warning signs here Id simply like to answer.
But again the owner wont answer and when he does it sounds awfully defensive to me absent response to these concerns. In fact the solution to all this offered was theres a tunnel that takes away the top two meters of tide flow. This is a solution? Come on....What sort of answer is that???





Dont forget Koolan was a sure thing and that one was collapsing three times in a month according in the above article I posted. Even with overflow absent seepage theres ongoing treatment and then even still youd need to see what can be present in the water to understand how lengthy that could be.
I see some great thought into solutions above. But yet others want to dimiss absent care. Its just a differing way of dealing with something limited by our own investment.
