Another post with zero moto content. I didn't even ride out. This morning, I had the opportunity to get a tour of a gold mine. We were asked not to mention the name of the facility when posting on the Internet. This is one of the medium sized ore trucks with a load capacity of about 250 tons. I think he mentioned that they move around 150,000 tons of ore per day either to the mill or to be put into storage for processing during the winter. The mill runs continuously year around. It was a pretty impressive operation.
This is the main pit. The darker material is stripped of and moved to the side. The grey material is what they were processing. It is very low grade ore and there is not "free" gold such as with placer mining. All of the gold is chemically extracted. The tour included an overview of the entire ore process. Mining is a major industry in Alaska and is one of the largest private employers in the state.
