Nunavut is one-fifth the size of Canada, so it's very hard to generalize east to west across the board.
In this community, as far as the carvings you might buy in town that are actually carved here--separate from carvings from other communities--the soapstone typically comes from Cape Dorset. There are a couple of guys here who have boats. They go out and quarry it. One guy has a 42-foot ex-fishing vessel that he sails down to Cape Dorset. It's fairly expensive. I believe the carvers pay around $2 a pound for the raw material.
In Taloyoak we've worked with the local community to access a quarry and bring the soapstone back by snowmobile. I don't have the numbers in front of me, but it's fairly costly. Also, you can only move so much by snowmobile. They're small quarries; there's no such thing as a large quarry as you would be imagining. The quarry could be fairly close to the community--wherever Mother Nature deposited it, basically. Some of it is out of reach as far as any kind of ease of transportation to get there, unless you're talking about some exotic means like a helicopter, which would be extremely exorbitant in cost. So there's no real generalization.
