The boulder is just the tip of the iceberg, so to speak.
An exhibit featuring a three and a half ton nickel-copper sulfide rock was dedicated Tuesday in the lobby of the Dow Environmental Science and Engineering Building on the campus of Michigan Tech.
The boulder, along with two smaller specimens, came from deep within the Eagle Mine.
Michigan Geological Survey Director John Yellich says they are examples of the wealth of minerals below the surface.
A geological survey in Michigan has not been conducted in over 30 years and there is currently no funding for one.
If a survey were to be completed, it could lead to further exploration of mineral deposits and, ultimately, jobs.
If the state were to fund it, a geological survey would include surface mapping and analysis of rock and core samples to determine what lies beneath.
