Oh, the Lykov family [https://en.wikipedia.org/wiki/Lykov_family https://en.wikipedia.org/wiki/Lykov_family]. The encounter was devastating for the family, because all 4 sons (aged about 20+ I guess) died of pneumonia they caught from the geologists (as they weren't vaccinated and never met any human pathogenes in their entire life). Only their daughter survived and she's still alive there, with a man who came to help her recently. But I doubt that they did well. They complained to the geologists that their metal dishes were wearing out to holes. They still did have some sickles to cut some crops, but I'm sure they'd get out of order within a decade too. Apparently, in such a small number of people it's impossible to produce metal and tools. There's a better example: "Happy People" documentary [https://www.youtube.com/watch?v=fbhPIK-oBvA https://www.youtube.com/watch?v=fbhPIK-oBvA], about a village of hunters on the Yenissei river, with only river transport to the civilization. It looks very romantic untill the end where you see nunters selling furs cheaper than they hope, and they still depend on tools and fuel.
