RE: Infrastructure
Essentially no infrastructure. That is probably the main reason that their really fine deposits are not valued higher.
To mine Hackett River there will be a need for a port at Bathurst Inlet, and a road from there to the property.
Sabina has the biggest most economic deposits in the area so their deposits may have to serve as the primary resource base for funding the infrastructure. (I could have said Sabina needs to be the primary fundor for the infrastructure but it could be that they will sell the properties to a major at some point, so Sabina won't necessarily be the one actually developing the mines)
I believe it is Newmont that owns a rich gold deposit, Hope Bay, up on the north east shore of Bathurst Inlet, but my impression is that they plan to have a small port of their own so they won't necessarily be contributing much to infrastructure that Sabina's properties will rely on.
It seems to me possible that the Canadian government might provide some funds to develop the infrastructure, a port at Bathurst would appear to be supportive of Canada's desire to consolidate its claims in the Arctic in competition with Russia. Also it would serve as a favor to Nunavut to help it with its economic development.
It seems conceivable to me that Canada might at least offer loans for the infrastructure development, which could be a big asset in that many large deposits like the mammoth Porphyry deposits in British Columbia require billions of dollars of capital expenditure and it is far from clear that anyone is willing to pony up such large sums for mines whose profitability would be very susceptible to metals prices as well as the price of oil.
