Professional Miner Achievement

[Captain Denton]

OK, I have a noob question. :P This achievement puzzles me and I failed to find any clear and consistant data on the internet.

"Professional Miner
Extract all minerals at one level"

As far as I understand this... this means to break all the foreground and background blocks that are coal/iron/silver/gold/mithril/crystals, correct? Because it seems I cleared all of that in the first campaign map and still, no achievement was given.

Did you check behind every mineral in the foreground if there also is something or did you replace the front with earth and missed something in the background as consequence?

If you want to check for minerals again, just select earth with your mouse and click on every block underground to see if the "replace" option shows up.

[Captain Denton]

I dug out the background tile as well if it was anything else than dirt. I'll try to check a bit more, hopefully I find the missing tile of ore...

[kevinshow]

One problem is that at some locations, even with your lights, here and there may be one block of coal set against a dark piece of dirt.

So check that kind of block also.

How does this achievement work; remove all the blocks from the map??

[Captain Denton]

It says to remove all the "minerals" in one map. Now I wonder what qualifies as a mineral.

[Stefan]

Minerals are what you listed in your first post: coal, iron,....

EAsiest way to get this is to strip mine a small map on easy.

Still a lot of work. You could spend an entire week.
.
Plus some minerals are directly above the lava. Mining those is a nghtmare.

Why do you think it's a nightmare? just build one more layer of earth above the lava and mining becomes very easy....

[Captain Denton]

I don't think strip mining is actually neccessary. Unless game-generated blocks have a possibility of hiding ore in the background (like dirt over iron, which I don't think is the case, if there's ore by default you see it in foreground as well). So a nice planned network of tunnels that are dense enough to reveal all neighbouring tiles is a winner in theory. Granted, my first map was also my first CtW playthrough ever, so that was not known to me and my underground is a chaotic disarray of holes and caves. XD

Minerals are hidden behind some earths. You can either look for all minerals by foreground and then use the dirt replace option to see where the hidden ores are or strip mine. Small easy map takes roughly 10 hours to do on x2 speed. The easiest ones to miss are the ones that drop by the red earth in lower levels.

[Captain Denton]

Wait... foreground blocks can hide ore by default? I thought all of background ore blocks had the same ore's block as foreground, unless hidden by the player? Because that would explain my pain then...

[mikeydsc]

The reason strip mining is better is because you cant manually control a dwarf and do the replace command. So that means each block that is replaced by the replace command will mean the dwarf walking to the stockpile to get 1 piece of dirt and walk to area that needs block replaced. Now with all the other activiteis you assigned this process can take a long time.

I usually mine the whole row manually and build my walkway as i go so as not to have dwarves falling off cliffs. Let the others come behind you to pick up w/e falls on the ground. The wave timer breaks up the grind.

[Ankido]

Oh, so it's just minerals and not the whole map. That's pretty crazy since I use portals to get around to minerals. Any good videos on someone doing this achievement. Looks interesting!

[Nocte Furorem]

It is possible for dirt to hide an ore block. Since I just got this achievement on a small map I'm now in the habit of collecting all ore by strip mining. So far on a new desert map I've just found one iron ore hidden behind a dirt block with a stalactite on it.
