Scandium International Mining Corp (SCY)

Hello everybody!
I'm new to the field of investing in mine stocks and as I was looking around I found this stock.
Currently I'm doing some DD and I'm not invested yet. The project looks very promising to me but I haven't really found out what the essential criterias for this succes are. I often read that people have a checklist when they are doing their DD. Do you see any obstacles on your checklist which need to be taken or which may lead to problems in the future? Or do we have to wait for further information comming with the DFS.

I have read that the numbers that appear in the PEA are based on the assumption that the exchange rate of AUD to USD is around US$0.90. Currently this exchange rate is at ~US$0.766 so approximately 14% below the assumption.
I'm trying to figure out in how far this exchange rate is relavant. I assume that the building of the mine, the operational costs and some of the taxes are payed in AUD. Is it correct to say that the profit will be made in USD and therefore a weaker AUD is rather good because the operational costs are lower?

TYIA for any help! I'm looking forward to get started :)
