We had been picking away at it, but the going was mightly slow. Why not use some explosives to advance a little quicker?
Rocks and minerals associated with clay seam gold deposits in southern Oregon are often in sedimentary rock units at least partially metamorphosed into argillite. They are also associated with mafic volcanic rocks, basalts and gabbro that...
Our theory was that a dredge would collect far more material in a shorter period of time, leaving us with ounces of gold every day.
In some areas these channels were thousands of feet wide, and just figuring out where you are in some of these diggings is a challenge.
Our destination was some old hydraulic workings where the old miners had washed literally mountains of material away to expose gold in ancient river channels.
Gold can potentially be found in all the glaciated areas of the Midwest, but to find it in any appreciable amount one needs to look to areas where the gold gets concentrated by more recent water flows.
