Mine

Mines are constructed on ore veins to extract Iron, Copper, and Tin, as well as various Gems. Ore veins are discovered using the Dowsing skill with a Dowsing Rod. Working the mine will produce ore upon success, and occasionally yield a gem of a set type.

As not all methods of ore extraction are completely resolved, there is more information and theories on the discussion page.

Operation

To work a mine, you must learn the skill Ore Extraction from the School of Architecture. To further increase your yield per mining attempt, you may learn the second level of ore extraction (7 tin ore, 7 copper ore, 7 iron ore). Each mine type has a different method of operation in order to properly identify which crystal to pick in order to get the ore out. If you correctly identify the crystal, you'll get some base amount of ore (e.g. iron gives you 3 ore, copper gives 3, tin gives 1, etc).

Aluminum

The best way I can describe it is that you want the most emissive crystal, the most... luminescent.
I've gotten very good return on working the crystal with the highest brightness. ~McArine
I've gotten very good returns using the crystal with the highest max(r,g,b) value. -Eldrad
The memory train works with aluminum, same as tin.

Antimony

There are two crystals of the 7 that share have similar color, but different brightness/intensity. Click the slightly more saturated of the matched pair. It can be difficult at times to spot the correct pair. Successive correct clicks will build a chain to 7.

Copper

Copper ore is extracted by clicking on the crystal with the highest color saturation (i.e. the "least gray"). Success yields 3 at extraction levels 1 and 2.

Memory Game for 4 per pull: Just as with Iron, once you get one correct, follow one behind on the most saturated. (Requires OE2+) ~Akhenallah

Memory Game for 5 per pull: Just as with Iron, once you get one correct, follow two behind on the most saturated. (Requires OE3) ~Juspar

Gold

At evry round there is a yellowish crystal. At odd round pick the yellowish one. At even round, check which one is yellow and pick his "linked" one. For examples, these are the rules working for the mine i have access, maybe rules are different for each mine(method confirmed, and each mine is different):

1. Top Left -> Bottom Left
2. Bottom Left -> Back Bottom
3. Middle -> Back Top
4. Back Bottom -> Middle
5. Back Top -> Top Right
6. Bottom Right -> Top Left
7. Top Right -> Bottom Right

Iron

To extract iron ore, click on the mismatched color crystal. Success yields 3 at Ore Extraction levels 1 and 2.

Memory Game for 4 per pull: By clicking on where the odd gem was one turn later. (Requires OE 2)~Zreyas

Memory Game for 5 per pull: By clicking on where the odd gem was two turns later. (Requires OE 3)~BillHicks

Lead

Figure out which crystal has gone the longest without being the odd crystal out, and click that one. When you find that crystal, keep clicking it until it is the odd crystal out. As long as you keep clicking the crystal that hasn't been the odd-one out for the longest time, you will build a chain up to 7 ore per pull at Ore Extraction 2.

This method is undoubtably the best, but it can be frustrating if you don't have good memory. In that case, try clicking on crystals until you find one that yields ore, and keep clicking on it until it doesn't, and repeat. If you have noticed a crystal change color recently, then it won't be the right crystal. JulianJaynes 15:28, 9 January 2009 (EST)

Also worth noting, with OE 1 my max yield has been seven. Does OE 2 buy you anything with lead? JulianJaynes 15:28, 9 January 2009 (EST) Max yield of 7 also appears to be true for OE2 as well. Zoser 11 January 2009

If you have pen and paper, you can use this method: Number the crystals 1 through 7. Write down the one that is different. Click it. Write down the next one. Keep clicking (it doesn't matter which crystal you click) and writing until your sequence contains all of the crystals 1 through 7. For example, here's a sample sequence: 1 5 5 6 4 1 3 2 2 7. At this point you have all the crystals in. Now, one way to keep track of which crystal should be clicked is to start at the end of the list, and look backwards for the 1. Keep your finger there, and start again at the end of the list and look for the 2. If you move past your finger, move your finger to the 2. Do this for 1 through 7, and you should be pointing at the number of crystal to hit. In the sequence above, the answer should be 5.

Another method also requires you to write out the sequence, but each time you write a number, look for the previous instance of that number in the list and cross it out. For example, in the above sequence, your list would look like this: X X 5 6 4 1 3 X 2 7. The first number in the list that isn't crossed out is the number of the crystal to hit. In the sequence above, the answer should also be 5. Suppose the next crystal is 4. Then you should write 4, cross out the previous 4, and you can see the answer is still 5: X X 5 6 X 1 3 X 2 7 4. If the next crystal is now 6, write it down, cross out the previous 6: X X 5 X X 1 3 X 2 7 4 6. Now if the next number is 5, write it down, cross out the previous 5, and the next crystal to hit should be 1: X X X X X 1 3 X 2 7 4 6 5. Oofafwet, who thinks way too much like a computer. 21 January 2009.

Much easier... get 7 sixsided dice, lay them out 1-6 and put a piece of tape or somthing on #7. as the color changes, pull that numbered dice out of the row, move it to the end. Always work the "top" dice, and the "bottom" dice is always the most recent color. (you're just pushing the stack) Gwyr 25JAN09

Lithium

Lithium appears visually as the "six crystals of one color, one of another color" system most commonly seen in iron mines. However, the simplest way to mine it ignores the visual appearance entirely. Simply mine each crystal once until one of them gives you 1 ore instead of 0. As soon as that happens, keep mining that crystal, and it will count up 1 ore each time until it gives 7 per iteration (due to the increasing sequence length of the memory game). At some point, the pattern breaks, it drops to 0, and at that point you cycle through the other six crystals until you find the one that gives 1 ore again. Rinse, repeat. For more advanced mining, you can usually predict what crystal is the new ore crystal, by which crystal was "lit" right before the pattern broke. If that doesn't work, try the first crystal that was lit after the pattern broke. That works about 95% of the time, but it requires dramatically more attention and only saves about 1-2 mining attempts per cycle.

Is there a way to predict when the pattern will break? --Xyrrus 21:33, 10 January 2009 (EST) No prediction possible from what I can see, had all random numbers up to 14, also had 4 1s in a row and also a 10,11 10 and 10 in a row too. --Fez

The correct crystal is the crystal that has been lit (odd one) the most in the last 7 pulls. That's how you predict when the pattern will break.

Magnesium

Click the blue crystal, or one with greatest blue component.

Randomly was able to pull 2 at OE2, haven't figured out the pattern yet - Penates It was the memory game Malard 19:03, 29 January 2009 (EST)

Platinum

Like Gold, each crystal has a corresponding crystal. This can even be it self. When a crystal is the odd crystal, work it's corresponding crystal. This can be done with the memory game, to gain 7 pr pull. The corresponding crystals are different from mine to mine. ~McArine

My experience is that the colors can at times be very close, so it's hard to distinguish the odd one. I don't know if there, like gold, is a specific color where the rules are different. This might be the reason why I couldn't keep a steady run of 7. ~McArine

the 'link' seems to vary from person to person - Elfus

Silver

Similar to copper: rate the crystals in order of saturation and pick the second from most saturated crystal. Using the memory-game to increase yield works in the same way as tin to provide up to a 7-silver yield (depending on length of sequence being repeated). The result of mining is "silver", and not "silver ore", i.e. it's ready to use and does not need smelting.

Strontium

Each mine has a different circuit, click on crystals in that order. one crystal can be present in the circuit multiple times. I have seen circuit with 7 to 10 crystals. Yield come from 1 to 7, then stays at 7. Color doesn't seem to matter in any fashion.

Tin

The correct crystal is usually most colors of green, red and yellow and grey even the washed colors (careful though they shades look similar). Also described as "Most brownish". Also described as lowest blue in the RGB palette or Highest green in the RGB palette. All of these interpretations give the right result. The exact answer isn't quite known.
Using colour cop program lowest blue on rgb scale is working reliably. Most obvious colours are brown orange red but very dark blue is sometimes the answer which can throw off the pattern unless checking with something other than sight alone. Possible to sustain 7 ore per pull using memory game- have not tried higher.
See discussion for more discussion (and history of the memory effect on mines).

Titanium

Mine the crystal that has remained the same the longest. You will receive ore in proportion to how many times you are correct, up to 7 ore after 7 correct pulls in a row. As long as you maintain correct pulls you will continue to receive 7 ore. OE level appears to have no impact.

Tungsten

Click on the odd one out, there are 3 pairs and a crystal that doesn't have an equal pair.

There also seems to be a kind of memory game, but have not figured out how it works: had results of 1,2 and 4 ore, OE2; Was finally able to mine 7 Ore per pull using the 6th last right Kristall with OE2, hope others can also verify -Pazifist

Zinc

Active crystal appears to be the lightest/whitest

I haven't found that the lightest/whitest works, i got a very low success rate using that method. I had much better results going for the 'strongest' colour, similar to copper mining, for example if there is a particularly vibrant purple colour this usually works to obtain ore. However there seem to be a lot of these 'vibrant' colours so i found it hard to tell which one is the right one, my success rate was still only around 60% so i may well have the wrong idea.

• From my testing it appears to me that Zinc is the odd saturation out. If you have 6 cyrstals that are vibrant and 1 that is dull, the correct is the dull one. If you have 6 that are dull and one that is vibrant, the correct is the vibrant one. -Kiya

• Ive been mining Zinc while getting diamonds and i confirm that the most dark or with the most odd saturation (similar to copper) gives me zinc ore. -Zezima

• The one with the odd saturation is the one. And you can do the memory game like on Tin. ~McArine

• Confirming previously described methods. Just find the odd saturation (sometimes the one not bright, sometimes the bright one), and play memory game for 2 Zinc ore per pull. ~Nkuku

Increasing your yield: the mining memory game

If you continually click on the correct crystal, you'll always get the base amount. If however you remember what's gone before and start clicking on the crystal that came up *previously*, then you'll get extra ore yield for as long as you can keep up the correct sequence. For example, if you perform a run consistently working the from a history of 3 crystal ago, then each pull will give you 4 extra ore. As soon as you hit an error in your sequence (because you guessed the wrong crystal) then the run stops and you need to restart your memory. It's easiest with iron where the correct crystal is most obvious, but the technique has been tested (Nicodemus) with copper, iron and tin.

As an example: label each crystal with a number. If it's the first crystal that's correct then write down "1" in your sequence. If it's the second crystal, write down "2", etc. When you've got the desired history length (e.g. 3 numbers written down), then keep writing down the correct crystal, but don't click on it. Instead, click on the crystal 3 back in your history. So, if a mine is giving a sequence of 1, 2, 3, 4, 5, 6, then select the first 3 crystals as normal (and you'll get 1 ore each time if this is tin) by clicking 1, then clicking 2, then clicking 3. On the next pull you start using your history instead of the current correct crystal and select 1 and then 2. Both of those pulls will say "no ore" because you haven't yet hit the correct sequence, but from then on (when you select 3, 4, 5, 6, etc) you'll get 4 ore every time so long as you keep the sequence correct (i.e. as long as you click on the correct crystal 3 pulls ago). The bonus pull seems to vary. With tin (i.e. a base pull of 1 ore), then you get a bonus ore per run-length of your sequence. That means that a sequence of 2 will give 3 ore. A sequence of 3 will give 4 ore, etc. For copper and iron I've only ever got a bonus of 1 no matter the length of the sequence. Whereas for tin and silver you can get up to a pull of 7. The 7 sequence appears to be the limit.

Note that if you're just mining normally and a sequence comes up "naturally" (e.g. the same crystal is correct 3 pulls in a row), then on the third pull you'll get the sequence bonus.

Saturation, Colour

Some mines require you to determine which crystal has the most saturation, or the second-most saturation (e.g. silver). Some ask you to pick "the most blue". Sometimes it's not easy to tell which one this is (especially if you have colour blindness!). The most important thing to do is to turn off the "time-of-day" lighting, since it really makes things harder to differentiate. If you've done that and you still can't tell, then try using some magnifying software that shows you colours. For example, on the Mac(confirmed : works on windows), you can run "Pixie" (a developer toolkit application) that magnifies a portion of the screen and provides information about where the cursor is pointing. If you enable the Pixie preferences "Float window" and "Show colour values", then you can easily wave the mouse over the crystals to quickly see which crystal is correct. Note that "most blue" would be the highest "B" value in the R/G/B section, whereas "most saturated" would be the highest "S" value in the H/S/B section of the information.
