Thought I would check out whats going on. Was looking like smooth sailing there for a while. The latest release is all about grade and access to it. MACA is the drill and blast team. They went in straight for the HG zone without doing any research on the rock. The blasted rock is too big for processing. This is why they also needed to upgrade the crushing circuit. It is possible the blasted high grade rock is too big to move with current machinery and you can forget processing. They are using more explosives now to get the rock to a manageable size for the plant. I think that is what they mean by "refinement". More holes more explosives get it as small as you can an then use a primary and secondary crusher.
Anyone seen the photo of everyone standing around a giant HG rock. There is most likely an entire area of them blocking access to the rest of stage 1. That was probably a small one and the biggest that could fit in the little Volvo haul truck. I also thought that somewhere I saw stage 1 100% complete and that means to me nothing left.
So if anyone wants to get angry. Give MACA a call. Not even listed on the their current project list,

Have to dig really deep in their website to find it,

I am not sure about Centro. Makes me think of a movie I have seen recently.
