I am still wondering as to how assays are completed when a drill hole core may be many meters long. From a visual inspection of the core, I assume that the onsite geo at the drill site will chose some specific sections to assay. So I sent an email to ActLabs.
(To get a more complete idea, I guess a similar email would have to be sent to Neil Novak in order to ascertain how he specifically would want assays completed for SPQ & NOT.)
Below is the email, followed by the reply.

To whom it may concern:As a layman who is rather naïve of the assay process, I was wondering whether you might answer a question or two.If a mining company had 50 meter drill core, which it suspects has PGEs, and wants to have it assayed …1) Does it send the complete drill core to your lab (cut in half) for pulverizing?2) If so, do you pulverize the whole length?3) Do you sample along the whole length or take random samples? Thanks,

GlennGenerally people assay 1 or 2 metre sections as a sample. We would crush the whole sample, mechanically split the reject and pulverize a portion.REgards
