Horizontally about 1000 m radius compared to 100 m radius for roads.
I think your right,where a railway ROW needs a gentle slope a road wouldnt and could get away with 8 or 10% grade.
One thing you dont want to do in that country is dig into permafrost,you build on top all the time on frozen muskeg or permafrost.
So theres no cutting off hilltops or cutting sidehills into slopes,once you take the top layer of insulating grass off muskeg or permafrost it will only take ten minutes of sunshine on the black dirt to start a process of melting you wont be able to stop without filter cloth and an insulating cover and a lot of man hours.
Theres a very delicate balance up there,anything man does will show up for years and years,our footprint is huge,just the fact that theres winter wheat growing at most camps shows workers have introduced a non native species from the seeds on their footwear.
Any work you do in the north has it's due diligence and that means any species that is disrupted will be replaced or have equal or better habitat made for that species somewhere else close.
A roads doable,I have been doing this **** all my life all over western and northern Canada,the logistics are horrible but also not bad if you know enough peeps.
Thats half the costs of doing a road job in the north is getting the equipment and supplies up,usually by barge a year earlier,nothing moves fast in the north.
From a construction point of view a road would need minimum 1.5(to be safe) meters of rock fill,about 8 fifty tonne rock trucks to haul it,2 loaders to load them,2 big excavators for stripping,2 fuel trucks,a crusher capable of breaking rose granite,a turn around for the trucks at the front of the road because the mines act states you cant back a truck up more then 100 meters so every 100 meters you waste 10 loads of rock for the turn around.
Theres so many lakes in northern Ontario and it just gets to be nothing but lakes the farther north you fly,thats the challenge is getting around them for any roadwork.Thats why it takes a 108 kilometers of road to get to a place 30 miles away as the crow flies.
We need some deep sea ports in the north,that would get mines running and maybe get some of our forces up there on a couple bases near the ports to show we are in the north Russia so fu*k off!
Allmost every exploration camp I have been in the last 3 years I have been able to see the gold in the core samples without a glass.
The Canadian shield is loaded with gold and precious metals.
It's a beautifull country though,I allways had a"blast" in the far north.Especially filming the blasters diving under a 50 tonne rock truck to avoid the incoming shrapnel.
