I asked the company and they said that they haven't completed the wireframes for ni and co as the data is less extensive than the data for the other base metals given assays for those metals were not previously undertaken. The aim is to do a nickel and cobalt study as part of the DFS but any reported resources will likely be inferred pending more infill drilling.
My other observation is having a big chunk of the high-grade now as indicated is going to really improve the already impressive economics and life of mine.
