4 trains a week will require 800 truckloads a week coming out of the ROF, or 41,600 loads a year. With road restrictions during breakup, etc, they may average 250 days a year of actual hauling. This translates into 166 loads a day. It will take a 12 hour day to make one round trip.

Or you can look at it another way;

In Cliff's EA, description May2011_Chapter 7, they need to haul 2.3Mt of chromite concentrate annually, 1Mt of concentrate goes into trains at southern end of all-weather road to port to China, 1.3Mt to Sudbury to make .6Mt of ferrochrome. Rail Haul requires 10,000 tonnes per train or about 231 trains trips per year

- 63,500 KGS = 70 tons
- 63,500 KGS - 22,000 KGS = 41,500 KGS actual payload capacity per truck
- 41,500 KGS = 45.7 tons actual payload capacity per truck during

- 2.3 Mt / 45.7 tons = 50,328 truck loads required per year to haul 2.3Mt

- 365 days a year (less winter thaw and bad weather allowance of 60 days) = 305 days

- 50,328 / 305 days = 165 truckloads per day

- 10,000,000 litres of diesel for mine X 12 months = 120,000,000 litres per year X 1.9 lbs = 228,000,000 lbs/yr = 114,000 tons per yr / 45.7 tons capacity per truck = 2,495 truck loads per year / 305 days = 9 truck trips per day

- 50,328 truck loads ore + 2,495 truck loads fuel = 52, 823 X 2 = 105,646

- 174 trucks per day X 2 for round trip = 348 one-way truck trips per day or 105,646 trips per year back and forth

- 60 minutes X 24hrs = 1440 minutes X 305 = 439,200 minutes in 305 days
- 439,200 minutes in 305 days / 105,646 annual roundtripd by truck = truck passes at any one point every 4.16 minutes on the all-weather road.

- Rail would require 462 one-way trips per YEAR.
