I don't know to what extent, they would be able to do this either Longbomb, but I just can't see them sending granite down to the lab. I think it has more to do with some parts of me [suspicious nature] not retiring from the NYPD when I retired 20 years ago. Yikes, man that is a long time ago. Lol. I'll bet you that outside of the geo's eyeballing the samples or cores, Sage will deny that they would employ the use of field testing/mini lab equipment to assist them.
I know you read these posts Michael O' Brien, so I am chuckling at you chuckling at this post. You know it is true lad. LOL.
Best wishes to you Longbomb and to you Mike,
