Lived in Cheyenne for a time years ago. Long story having to do with missiles, the Air Force base and so forth. Wyoming's solution to any problem, whether rattlesnakes clinging to highways for warmth or site clearing for housing, is dynamite. It's cheap and it can be fast. Light it, through it off the back of the flatbead truck into a swirling mass of rattlers and problem resolved. Save for the potholes of course.
Not sure explosives are what you need to look into with this remaining slab situation. But there may be a firm offering such an approach near you for cheaper than other alternatives? Explosives, I hope, are not a DIY option though. I've only used such demo guys a time or two but found them surprisingly competent, coherent, and inexpensive compared to alternatives availed me.
I guess I am not clear as to why this piece alone remains? The jackhammer on the bobcat could not reach it or something about it was resisting attempts to break it apart? If it is just chipping I am worried your attempts to drill it with the usual will be equally frustrating. Do you think it alone was a section that got steel mesh, rebar or something?
What about the most fun tool on the planet rented for a weekend? A handheld one or two man jackhammer (with earplugs please).
