Gemstones to Die For
November 2014 by W. Dan Hausel
Some gems can potentially poison you, make you sterile and even make you forget who you are.
The Challenge of Winter Dredging

Tips for Detecting Nugget Patches
Following Clues to an Old Mill and Vein Strike
My last update on this adventure was in the April 2012 issue and involved our search for the northern extension of the Cedarberg Mine. At that time we had found it and we were in the process of returning for some detecting when Mother Nature struck with a late rain and snow storm.
