I am looking for tungsten and just want to be clear about going planetary prospecting without wasting my time. How do I get a load of tungsten? I can use EDDB and select tungsten and vulcanism but I dont know what it means by water geysers etc and tbh dont know what vulcanism actually means. How do I pick the right planet to get it and will I find geo or bio sites to get the most in the shortest time? Do I need to DSS the planet before landing?
