One of the partners in a massive and contentious proposed gold and copper mine in Alaska is pulling out, raising questions about the future of the project.
Q: I’m a fairly new dredger. I was told that the black sands contain fine gold that is tough to see and recover, so I have been saving the black sands when I do my clean up. What method should I use to get the gold out?
Greenstone is a dark greenish-black basaltic rock which, along with chloritized schist, forms belts up to 50 miles wide in northern Minnesota, in rocks of Late Archean age. Most belts are 2.6 to 2.9 billion years old.
I could see lots of quartz, both loose on the hillsides and in the numerous small prospect diggings. There was a small gold rush here more than a century ago.
Rotten rock (saprolite) can be found in all warm, humid regions, but is best developed in humid, subtropical climates, like that found in the American South. Outwardly, it looks like bedrock, but upon closer inspection, it can be seen that roots penetrate it and that it can be worked with a shovel or hydraulic monitor.
