>>1507529We have the same situation here, the dredges went down about 30 feet but the gold deposit is 300 feet down in lots of places. We're seeing mining companies going in and target drilling the glacial till and then going after the hot spots with open pits and even underground workings through the loose dirt.
>>1507530our access problems are more to do with private property, but in our case they ran a highway right through about 20 miles of dredge tailings, so you can find gold on the side of the road in the highway easement.
One place that interest me in my area a dredge accidentally dumped almost a thousand pounds of mercury overboard over 100 years ago. I have a feeling that mercury is on the bedrock now and full of gold. It's public land though, so not much hope of getting it even though bedrock there is remarkably shallow. The US has gotten extremely protective of its creeks and wetlands.
