IDR is a ticker symbol. A company I have owned since about 2011. A penny stock under a different symbol back then. 

Believe it or not, unlike many mining companies, they actually have earnings! When I toured their underground mine they were hi grading it with the hopes of some day doing an open pit mine in that same vein if silver prices got high enough to be economical (much lower grades). I looked at a bunch of drill cores and toured their facility. They actually had a flotation operation in Kellog where they processed ore for several small local mines. Of the MANY penny stocks I "invested" in and went belly up, this is the one that actually took hold and did something. I bought a bunch more back when it was still under a dollar a share, remembering their open pit hopes and remembering they had proven ore grades.
