RE:Regarding cores - I spoke to a CEO this week about this
braindeadoldguy wrote: His answer to me was this:
When the cores are brought back to where they store and check them, the company decides which ones they will send in to the lab for assessment. There is no sense in sending blanks, as it is very costly to send cores to the labs without a return of decent grades. So, they inspect them first, chose the ones to send, and off the go. They try not to send duds or very low grades.
Now here is the important part. ALL core results sent to the lab must be reported and their grades released to the public.
So - IMHO
So to take it a step further, you can imagine plotting the drill holes on a map, marking the good ones and their grades, and also the duds. This gives the geos paramaters to work with and within to flesh out the potential ore body. When you have such a layout, a picture forms and you can then make a decision where to go next.

Yes geologists log the drill core back at the core shack and take detailed notes on every inch of drill core. They only send what they think will run gold into the assay lab. It's a big waste of money to send in drill core that they think doesn't have any gold in it. Why would you do that? My guess is in a drill program like this with 200k meters they might waste a couple dozen drill holes that don't hit anything. So they wouldn't get those assayed wasting time and money. You just take detailed notes while logging the core. Those holes are not required to be assayed or reported to the market as I understand it. I hope this helps.
