Some may recall late last year I had done a page illustrating how to value a company such as rau.
I have just updated the main page and illustration for enterprise value per ounce etc. (been flat out or would have done much sooner)
For those who want to check it out, link below.
Cheers
(was going to upload the link, but not clever enough:(, sorry you'll need to cut & paste)
