For more than 40 years, iron ore prices have been decided by private negotiations conducted between the largest of the iron miners and the largest steel producers. These two sides dominate both the spot and contract iron ore markets.
The favorable geology of the northeastern and central parts of the Seven Troughs Range are the parts most interesting to prospectors. They are underlain by a thick sequence of Tertiary volcanic rocks, mostly rhyolites and andesites.

The Nevada Senate introduced SB108 in 2009 to prohibit PVC piping utilized by miners to stake mining claims.
The historical AJ mine, located east of Juneau, Alaska, was considered the largest gold mine in the state at one time. Joe Juneau and Richard Harris struck gold there in 1880, and it has been more recently known as a tourist destination.
After a host of companies spent 20 years prospecting, a mining firm is ready to make a play on the $2 billion lode of gold sitting in Eastern Oregon.
