While the capex on an EV battery is currently significant, it certainly isn't because of the diesel to dig it out. A big operation would probably have a rock truck like a 793F that easily holds 250 tons in a single load despite 500,000 pounds looking like a huge number. I think we can assume it doesn't take all 1300 gallons of fuel in a 793F's tanks to drive a few miles round trip. Maybe a few gallons? A 740 truck would do that in 6 trips probably in under an hour and that burns about 5 gallons/hr, but the bigger trucks are more efficient. So worst case maybe $25 in diesel and another $25 for the excavator?
