I have a small piece of this exact same thing. I too found mine along a railroad. After researching it online, I am fairly sure that it is Galena. Look it up and see what you think.

I have one just like the porous one you are showing. I have had it for 53 years and found it in the mountains near a lake in Calif. I have taken it to many rock shows and no one can ID it. I am presently having it analyzed at a nearby college to determine the gravity and metallic content. I wonder if you ever found out any more info on yours? I found it to be somewhat brittle with a drill bit. I was a welder for years and I can say that it is not slag.

Expertise

I am an economic geologist. An economic geologist does mineral evaluations and appraisals of mineral or mining properties. I can tell you if your deposit has value - remember that a mineral deposit, no matter how good, only has value when mined. Any value assigned to a mineral deposit, in the ground, is only the speculative value that deposit.

Experience

I have been a economic geologist for most of my 35 year career. Although I have done work in perhaps 45 states and numerious countries much of my work has been in Appalachian coal, intermountain west gold and silver, and Arizona uranium.

Organizations
Past President of the Virginia Section of the American Institute of Professional Geologists and a certified geologist in twelve states.

Education/Credentials
BS Degree from Eastern Kentucky University. Work on MS Degree @ Eastern Kentucky University, Colorad School of Mines & Marshall University Numerious short courses on the value of mineral deposits and how to value same. Also several short courses dealing with the different types of geologic processes; sedimentary, igneous, metamorphic along with the mineral associated with each.
