Mining question

[lamxuyen1234]

i found an ore node recently, but now that I'm mining for a second batch I got this weird thing happen. While mining on a same wall, my ores sometimes come at 18.2 and sometimes at 18.7 quality. Is it normal to have the same wall give 2 different qualities?

Yes. There are also softcaps on tool used and character masonry.

You can imagine it like a temperature map like this one

Each tile is a meter and all have basically a different quality, the map changes depending on what ore/stone you are mining.
so you can find high quality ore next to crappy quality stone.
