Edgy,

NOT pipe was about 100km and the cost estimate was some $100M?

So, ~300km to Nakina area (to feed the Gas Super Converter) is not really that long. See link below for pipe in that scale. The cost estimate was $600M for 420km. So, a (very) rough guess would be some $500M for ~300km pipe, give and take. This is less than the 50% of the cost for CLF private road. BTW, Nakina is on the TransCanada Hyw and TransCanada pipeline, so not too bad a place for a Gas Super Converter. Presumably, a power corridor is nearby for electricity. If not, then KWG could build a co-generation facility to generate electricity with natural gas, as well. Any "waste" heat could be recycled to keep the place warm. That gas burner can do many tasks...and natural gas is abundant and cheap (cheaper and more reliable than wind and solar). What would one do if there is no wind (or high winds which may tear the wind turbines apart) and when the sun goes down at night, every night. The days are short in the winter here in Northern Ontario, and a snow covered solar panels would be no good to collect solar energy.

In addition to goodheart's comment (liner replacement option), there is pipe coating technology to address the effect of corrosion as well. Also, the operators can optimize the particle size in the slurry to minimize the effect of corrosion.

As an aside, NOT may want to joint this venture for its chromite development. And as a speculation, NOT may want to consider transporting Ni concentrate using a 300km pipe. This could be in a separate pipe but in the same trench (to save cost of digging, etc).

Don't know if it would be feasible to "schedule" the chromite run and a Ni run, using the same pipe? Any experts out there?
