Ah! Thank you. I'm with you now. It's a good question. Maybe the answer comes down to whether they think they have hit the conductor with the RC (which I don't think is the aim is it?). Assuming the diamond tail's job is to target the plate then you would have to put only modest store in the XRF from the RC wouldn't you?

The POS model is for concentrated not disseminated bodies isn't it? So it's quite possible to have little showing even nearby. That said, if nothing's showing at all, management would probably be nervous about proceeding with DD. Personally i would do it because I think we need to understand what's generating the conductor.
