Jack I did find an assay company in Ontario that only tests for gold so Glenni is spot on.
Out of consideration for the lab I won't disclose the name or contact information for fear they might be inundated with inquiries asking about the samples. I would imagine unboxiing 2000 samples would take a great deal of time, and effort. If too many calls came in the results might be delayed.
The name is well known in certain circles with an almost mythological standing in the industry which is unheard of.
