What examples of digging through that amount of ice for the purposes of mining are you familiar with? What's a good example?
It'd be interesting to understand how much the environment there increases the cost of mining. Anything is possible, but it'd be cool to know whether it makes any sense. (and yes, I think our leadership in the US is fully capable of causing an international crisis over mineral assets that would in financial terms be best left in the ground)
It's not for mining, but the US built Camp Century and Camp TUTO in the ice to determine how feasible Project Iceworm would be. A construction film about the former was declassified some decades ago [0]. Icefield construction wasn't feasible even in the context of cold-war era MAD spending.
Actual subglacial mining has only been attempted a few times. Kumtor gold mine in Kyrgyzstan is in the middle of a couple glaciers and reshaped the landscape to redirect the glaciers a bit. Svea Nord in Svalbard ran tunnels under a glacier for coal. Canada's Granduc mine wasn't technically on or under a glacier, but it was just below one.
If “non experts” aren’t welcome, can you establish your expertise on the topic? In particular, what’s your experience with mining thorough ice or maintaining industrial operations in the Arctic or near-arctic conditions?
The main problem with ice, is that it moves all the time. The glaciers on Iceland move up to 46m per day. Also, any tunnel created in fast moving ice could easily be crushed by the pressure of the ice.
Greenland isn't entirely covered in ice. Take a look at any of the mineral resources maps floating around for the country. Everything's on the coastal margins in places only covered by seasonal snow. The interior is a big blank because no one's been able to search under the ice.
However, the adjacent Canadian provinces (Nunavut & Northern Labrador) share many of the same geologic provinces, also without significant glaciation. There aren't a lot of big mines up there relative to the mineral wealth because it's simply too challenging. Constructing big infrastructure in the arctic takes resources approaching nation-state levels. Most mining companies can't muster that or maintain it long-term.
Don’t modern mines remove everything over a very large area? It’s not tunnels and pickaxes any longer. The trucks are the size of a three story building.
Start with a few bunker busting bombs, work outside of winter, dump ice, dirt into ocean. Sounds plausible.
I'm glad the resident HN tech bros are also Arctic mining experts. Surely they wouldn't complain about non-experts writing clickbaity articles while making claims with no evidence themselves.

I imagine it is a lot easier to just strip mine Australia.

But you can do both. It’s about marginal profitability, not absolute.
Do people think we must pick just one place to mine?
