Minimum sample needed to be sent to lab for analysis from drill core? (1 reply)
Please join and login to participate and leave a comment.
Hi
I just want to know how would I go about to determine if the sample we are sending after processing a half core is representative of the lot it is from?
We start with a whole core that is halfed, sampled in 1m samples that is equal to 2/3kg that gets crushed and split to more or less 1kg from which 200g/100g samples are taken respectively for lab analysis.
I just want to know if this 200g/100g is representative of the start 1m sample?
