Question re: Fuel ExpenseI know that years ago, Brazil was able to change over their domestic consumption of gasoline to an ethanol (cane sugar based) product for domestic cars which had a huge impact on their balance of payments in Brazil as they produce a huge amount of cane sugar. Does anyone know if the trucks and machinery run off of more expensive diesel/gas or on a cheaper ethanol based product. I realize that gasoline/diesel is historically cheap right now but even gasoline should start to creep up over the next year or two. Fuel expense is typically the number one line item expense at mines.
