Thanks to those who keyed me in to using CLR for removong rust from rocks/specimens.

This rock wasn't found with my detector. Got it quite a few years ago from the Mactung tungstein exploration camp on the Yukon/North West Territories border near the portal. It's heft made me interested and thankfully the chief geo at site let me keep it. Years it sat in my collection, but once I got my GM1000 I tested the more interesting rocks in my collection. This rock detected constantly in the non ferrous and strong. 

It sure cleaned up well, and the blue dotted pic is the Scheelite fluoresceing under short wave UV light (Calcium Tungstate, CaWO4)

Cheers!
