Modern Mining Reclamation
September 2015 by Chris RalphA study showed that between 1930 and 1980, only a quarter of one percent of the land in the United States was used in all mining applications combined, including surface mining, tailings disposal, underground mines, and all mineral processing facilities.
The holes were overloaded with explosives, but I didn’t know it. I was just a green mining engineer fresh out of school and told to watch as the experienced miners set the charge.
The 15 rare earth elements were discovered long after the gold rush began to wane, but demand for them only took off over the past 10 years...
When we last heard from Ernie, he was still in Honduras and we were anxiously waiting to hear how the set up and training went at the mine. It got a bit complicated after that.
While mapping, I also found rock chips in the soil that were characteristic of the same wall rock alteration that occurs adjacent to the known lodes in the greenstone belt.
They worked their plan, bit by bit, and sure enough, after the blast, gold was detected… Over two pounds of beautiful crystalline gold was recovered in that stretch!
Not long after this, I was camped out with the geologist beside the Similkameen River where he showed me the evidence that an ancient channel existed on our claim.
Common thought is the switchback slows the velocity of the rushing water and gold drops out from the cut bank to a fill gravel bar within or below the switchback. I am not going to disregard that model; however, I hope to improve upon it.
