RE: BCSC
RE: BCSC >>>The -1s are merely a statistician's way of giving that 'block' a zero weighting for the purpose of the overall resources while incorporating the block for the purposes of the pit design. I do not think Robert Holland quite understands this, but other geologists will. Anyway that is my opinion.<<<
Given that the report did NOT define a meaning for the -1 values, it would be folly to make any assumptions, unless of course there is a CIM standard related to -1 values :), and of course there isn't. Since there were 2600 pages of rows with a -1 grade, I'd say that is a pretty big gap and in itself was more than enough to bounce the technical report. From a data engineering point of view, using a special value as a flag is extremely sloppy and not something I expect to see a professional use. JMHO.
