Yes I do get your point, liquidity in tiny micro companies can be a real problem, SAU is no exception.
I don't want to sound like a ranting SAU supporter however I see this companies worst case scenario with in 2 years is banking 5- 10 million yearly. Assets in Australia and SK will easily produce this type of revenue. Now for the up side, SK assets could potentially be billion dollar reserves. Even if they aren't, they certainly would have a plentiful supply of good quality ore for many years of production.
As for the other more exciting companies in this space, well their SP may have risen sharply but believe me they can fall far quicker and it will hurt.
