Hello Jeff and Graham,

Exactly.....but a step further. I would suggest going further than just
saying what the lithology is.
That was done in this case in the write up.
Okay, so we have as an example Katol #4(?). If you say it has a metal
rich lithology....what is it?
Everything past that is guess work and opinion if not studied.

It's like calling all the lunars by one name....after all it's only one
moon....as a gross example!
