Dredges actually do pretty well in freezing conditions. There are a few tips you should know, however.
With successively lower temperatures as the water mixture cools, new sets of minerals are formed and many of those stable at a higher degree of heat became subject to alteration as the temperature progressively moved lower.
Ore testing and other advice for starting up a mining operation.

We continue to seek out a patented mining property with an owner who is willing to host such an event with a water supply and enough remaining gold to make it worthwhile for the students.
