Ann: Intermediate Sulphidation System Identified at Riqueza, page-83

It's a staged approach.
Do the geo-phys first to focus on overall project.
Then do the rock sampling across more focused areas - this gridlike sampling is to identify (as i understood it) markets of what's below and only once that is complete do they look to drill.
This ultimately means they give the drills the best chance of hitting what we all want it to hit.
so in short no definitive date but the systematic approach to it gives me a great deal of confidence in then both conserving cash levels and ensuring accuracy.
