Yes, Loan 1 is due March 31st 2018.
TFA&B are due September 30th 2019, and Loan 2 is due October 1st 2019.
From the Q3-report (page 13) it seems to me that SIAF is able to negotiate how many shares they have to give as collateral; "resulting in a total of 8.45 million shares issued as collateral security averaged at $4.35/share, which remains at a favorable margin when compared to the market price of $1.40/share as at 30.09.2017".
In the meetings Solomon had in September he said that he wanted to repay (some of?) one of the loans earlier. If so, then I assume it will be Loan 1 (since it is due "soon").
SIAF has also said that the increase in collateral shares is reversible, so we should see a decrease in shares as the PPS increases (although with an average of $4.35 collateral share we should not expect that to happen until we have a significant increase in PPS).
