Inside Norton Gold Fields: Q A with Toll Treatment ...

There is nothing new about toll treatment per se, and it’s fairly common for small mining companies to ask larger companies to process their ore, otherwise they might not be able to mine at all. However, what is not common (and I don’t know of any others who are doing it), is for a larger company to actively promote toll treatment as a service to smaller companies.
