Nice find ! From the photo it looks sorta like jasper, which I would think might be unusual for that area. It doesn't appear to fit well into any of the "classic" point styles I am familiar with from NC. so I would just generically call it a constricting stem point, and would broadly date it from 1000 to 4000 years old. I think it would pre-date any of the tribal affiliations reported from the European contact period.
I wish I could train the crawdads around here to elevate artifacts from the earth. HH
