FAIRBANKS- The Bureau of Land Management spoke to the Alaska Miners Association about changes to placer mining standards. This morning’s meeting at the Regency hotel brought in about 50 miners. Organizers say BLM’s presentation was encouraging because they are seeking input from miners. Placer Mines often disrupt the surface of the earth, by sifting sand and gravel for precious metals. In 2012, BLM created new placer mining policy intended to reduce damage to public lands. New policy includes higher standards for environmental data before mining takes starts and during placer mining operations.
