No ore turning up on maps

it used to be when i started a new game there was heaps of visible ore on the sides of mountains, but now i only see one coal vein max when i start a new game and it has a location that says it should have more ore. unless they removed the ore lines from the sides of mountains now completely and you just have to dig stone to get ore now?

hmm kk so it seems all the other ore doesnt reach the edges and you need to use the ore detectors to find them is that correct?

Walking all around the map can reveal more in the sides of hills and mountains. I see more ore easily in the Desert and Highlands biomes compared to Temperate and Arctic.

yea the map is revealed, still doesnt show anything XD
