Getting their exploration license reinstated is a material event and would demand an 8-K to announce it. They would issue the 8-K immediately, given how significant an event this would be. No SEC filings since March, however...
And yes, they need the exploration license back in order to resume their application for a mining license. No mining license; no mining of course.
They've held the Guinea project since 2014, so it's not quite a "new" project. And they've done little on the property in those 6 years compared to your average junior explorer out there.
The market rightly decimated their share price for losing the license; it was their core project, the valuation of the company was based upon the potential value of the gold resource at Mansounia. And they lost the license...
And I don't think they are actively working in Ghana, at least there's been no PR's on exploration results from those properties, ever...? Probably because the properties are not worth spending a dime on.
Exploration is expensive and these guys are paupers; otherwise why do a convertible debt financing for a pittance that dilutes your share structure by around 90M shares.
