Andrew1234:"All of this activity has got me thinking, if this becomes a major Potash basin over time, and transport is the biggest expense, is building a rail line out of the question?"
I think this is the answer for your question:
"Price said the cooperation the company has received from San Juan County has been outstanding. In return, the company has committed to have offices in Monticello and employ as many San Juan County residents as possible in the slurry and trucking operations.
The upper end of the plan would ship up to two million tons of potash annually by truck to a railhead in Flagstaff, AZ for distribution across the nation and west to ports for shipment abroad.
TRH estimates a workforce of 250, in addition to the truck drivers and mechanics that will be necessary to move the potash to the railhead."
