The properties ARE attractive, and they'd only be suckers if they paid far too much for them. The drilling was decent in terms of initial coverage, but didn't go down far enough in many cases. GMM proved there is a lot more resource down there, but they can only quote resource they can confidently estimate via drilling.
Keep in mind some companies are now kicking themselves after locking in pricing in 2015 for spodumene and it went up significantly, but they're still obliged to sell at the low price point. Spodumene's higher cost of production compared to brine, is the downside.
