I would say i went around 500 blocks in each direction around spawn but literally all the biomes with different top soil/generation patterns had chert sand/gravel and dirt with chert stone top layer. I was aiming to get Tin since it's simpler for alloy so i'll look up which stone they spawn in, since i might need to travel much further. All the cave mouths i prospected were majority Hematite, which is nice but without bronze it's not too useful atm lol.
Interesting. I didn't find anything worded above Poor unless it was copper, so i'll be going off that in future. I did notice the Cassiterite started getting better readings in one of the biomes i searched, but if generation works like that, it makes it easier to play hot and cold. Prospecting pick mode? F i assume?
Just curious but do you prospect a 5x5 area (minimum)? Would you recommend looking for Tin or perhaps another resource for alloy?
Thanks for both of your in depth responses.
