Airstrip & Dibete have nothing other than already known copper and silver. They hit some massive grades of copper but it didn't continue.(disseminated rubbish).
Market loved it when announced when was BML. Because most of the market doesn't understand exploration many are left holding the carrot and continue for years because they can't fathom the thought of making a loss.
Maibele is not economic. How many times do I have to say this?
Where's the Feasibility Study they promised a few years ago?
Airstrip - It's been drilled many times over.
The company will tell you what you want to hear. Been there done that for years.
Next they will drill Takane if they renewed the licences in the last few years.
That was drilled with no success too.

Nothing in Botswana for Sigma.
Their best bet is in WA looking for gold.
