Study on Arctic Mining in Greenland, page-35

Smart setup by using the existing infrastructure from the previous Blyklippen operations such as the buildings and the waterfront infrastructure.
At this exploration stage the 2 drilling rigs seem just fine for the initial core sampling.

I agree with MrPiggy that Greenland is a tough place and difficult to operate.
Then again it is a safe jurisdiction, in close proximity to cheap green processing power in Iceland, in close proximity to the future 100GW battery factory of Freyr in North Norway and its close to the US which is looking to secure battery commodities.

In a nutshell, high risk high possible returns and how the above plays out in the CNJ business case is beyond my insights.
Hope this helps
