The one hole that might have gold is likely to have less than 5m at 5 g/t (they pretty much say this from the visuals)
These results won’t make one iota of difference to their situation imo, and they are months from proving up any kind of significant additional resources at Sertao.
They cannot afford to drill and explore - they’re burning cash hand over fist. They’re highly unlikely to be a profitable gold producer any time soon (based on three years of failed attempts at getting gold economically out of cascavel, based on their geological rhetoric and abstract videos rather than any sound measurable fact)
