Prospecting cave walls

[Grable]

So the wiki says that cave tiles with ore have empty layers to be mined first. Sometimes these layers drop stone.

How often does a tile with ore actually drop stone when mining?
I'm asking this because I have a huge cave system to check for ore and would like to quickly filter it checking whether the tile is dropping stone or not.

Thanks in advance

Tile either gives ore or stone. Not sure if I understand your question entirely though.

I think this pretty much answers my question. Was asking whether an ore tile can drop stone too when mining.

And this is what confused me

Also, mining spots now contain layers, you must mine all the layers before getting to the core to get some ore. Layers can sometimes contain some stone, but mostly they have nothing.

Thanks for pointing this out. It's always good to know where the wiki needs some work.
