Somebody remembers SBLG?

At the beginning times of FS2020 there was a deep hole in Northeast Brazil. The terrain was about 11000 Ft (which is too high for Brazil) and there was a runway in a deep hole, may be at about 2000 Ft. It was funny to look at. This airport was named SBLG. SBLG does not exist in Brazil. And all SBxx airports are bigger airports. Now, after almost two years I tried this location again and SBLG still exists, but now at a real elevation, a gras runway about 3000 Ft long. Position: 6°02’20"S, 36°27’26"W. If you look at this position in Bing Maps or in Google Earth you can find this runway. Does anybody know the real ICAO name? I couldn’t find it. The real name is definitly not SBLG as it is in the simulator.

Its name is Lagoa Nova, and its ICAO is actually BR-0115 according to this link:
