Ann: Exploration Update, page-65

That's been sorted out. The environmental licences for exploration are granted so that won't stop exploration drilling. The holdup is the assay method - no use drilling more holes without an assay method:

"IPAAM (Amazonas state environmental authority) has granted two-year, renewable independent exploration environmental licences for Ema and Três Estados. This will enable the completion of the planned diamond drilling programme at both localities." March 14th 2018

What's happened since then is that somebody has decided that IPHAN (national heritage authority) need clearance before we can mine. A bloody joke given half the country is farmland.
