The first exploration target Wondima is an oxide cap of +50km^2 and got a potential of 700m - 1 billion t.

Best part for me: they will receive funding of 30 million $ by the chinese (CIF) when they just prove 350 m tons with the next news release. And these chinese don't mess around. They are huge in Angola and already got an operating mine with a british company (Bellzone) a few miles away from WAI's property.
