If today's sp is not a reason to buy then there never was any before. Sure the price was well below a dollar before but that was when the assets backing the sp were a third of today's. Today's price is as good as it was then but today you know that sooner or later there will be a mine. Then you did not know that.

Also today there is public interest and at least from one mid tier company, then there was little. It is a different world now so if you find no reason to invest now then perhaps an examination of investment reasonng is needed.
