$2m range resource loan

There is a comment on the FY12 Financial Report that $2.1M was advanced by RRS to CCC, care of Pete Landau.
With $287K expense incurred in relation to the loan, as of 30 June. Correct my numbers but isn't that a 13.6% ROI in less than a year? Would it have not been cheaper to borrow from a bank?????

Principal and interest are due to be repaid on or before 31 Dec 12, that line to me indicates this has not been paid since there has been no disclosure to market. Does this mean that $287K expense line could increase?
Also does not state what this loan was used for???
Why would Continental Coal be borrowing from RRS, when there was the Socius Funds from the RI and supposedly positive cash flow mines?
