Hey guys.

I'm looking for recommendations for assayers. Simple gold and silver assays. Prices keep rising and many places have minimum order requirements.
Must have's:
-Professional
-Reliable
-Print out report or email but has to be on a professional looking assay sheet
-Under $48

I've used Reed Labs in CA when it was $40/sample. Professional and good print out. But now $48
I've tried Lawrence Hittle in CO. $35/sample. Not enough info to comment on accuracy. No professional report.
Home friend assays but at this point I need some "official" reports.

Any suggestions?
Thanks

Look up Hazen in Golden.
I see they do fire assays and I remember them as being a reputable group.

I’m the assayer at the mine I work at. Problem with using larger companies doing assays is that they don’t really have an “assayer”, they have “assay technicians” who really know nothing about assaying other than mixing a standard-across-the-board flux.

To get a true assay, you need to have an actual assayer conduct a custom assay, using a custom flux, depending on whether it’s a carbonate or silica based ore, and depending on the levels of barium, tellurium, and other elements. A true custom flux assay will usually cost a bit more for the first fire, and less for each consecutive sample if you continue sending in samples of the same host rock composition.

Where about do you live?

Send me a message, I can help you out. I have a little lab here where I do stuff on the side. How many samples do you have? Are they already crushed/pulverized?
