E,
My memory from past discussions was that the gold processor used by SGR was in Ontario near Oakville, just west of Toronto, but I cannot find a refiner there. However, Brampton is in the area so perhaps Johnson Matthey is the one they were referring to (someone else could perhaps verify that).
Meanwhile I had a look at Johnson Matthey's website and it is quite interesting to look through as it provides interesting information on the process of refining gold:
