Both of the, have same productivity, both mine ore + chunks, but Deep Core Drill costs 2x to Moho...
Here is screenshots..

Hello the screenshot doesn't work.

Yes both Deep Core Drill and Moho drills mine the same Ore Patches that appear when ore si mined out but the difference is that Moho mines directly Ore and the Deep Core Mining drill mines Ore Chunks that need to be refined before getting usable Ore.

However the refining yield much more ore as it is more complex to setup.

But I see Moho get raw ore AND chunks, and Deep core on the same patch, gets ore and chunks.
On some patches both gets only raw ore.. But always result is same for Moho and deep core.

Are you using the mines normally or with an Editor mode ? Because my mod makes a special action when you place the miner so Moho only mines an Ore Patch and Deep Core will mine a Ore Chunk Patch.

No, I don't use editor mode. But I have a lot of mods connected, maybe something else affects the situation?..
I can send you a save game file if that helps.

Yes that would help to check what the issue comes from if any with a save file.

Be patient :) on my Ryzen 5900x / 64GB RAM / NVMe Samsung EVO 970 this modpak loads about 10 minutes :)
I leave my character at that mining site, I wrote above.

And please don't laugh at my factory - I'm still just learning :)))))

Sorry I can't download the savefile my brower says it's a dangerous website and prevents me from downloading it. Can you past me the mod list instead ? I should be able to reproduce the issue from this if there is a mod conflicts (which is probable if you have a big mod list).

Sorry.. max message size doesn't allow to insert full modlist :)))
Maybe I can sen U save via Discord?
My nick is the same :)
