How much is a given resource worth? Knowing the answer to that can help you determine if it’s worth doing a particular repeatable mine or clearing an optional section of a mine to get that resource. Initially you might think that a resource is worth the amount of energy it costs to clear the tile that gives that resource. However, the game doesn't give you the opportunity to clear as many of those tiles as you like - you have to do the repeatable mines if you want more than you come across in regular gameplay. Some resources are worth much more than their tile, such as gemstones. These are resources that it's worth clearing a lot of empty tiles to obtain. Some resources are worth less than their tile cost (notably, rice) so it might not be worth collecting them even when passing by them in regular mines.

It's not as simple as saying I spend 100 energy in the repeatable mine for lumber and get 10 lumber therefore lumber is worth 10 energy each. While doing that repeatable mine you might also get some other resources so you should take that into account. Also sometimes there are multiple mines you can do for a resource.

The values listed below represent the average amount of energy you need to spend to obtain the given resource by doing that resource’s repeatable mines while taking into account the value of the secondary resources you obtain while doing the mines.

In the detailed calculations the “raw” value is how much the resource costs if you ignore the benefit of gaining other resources during the mine. The “adjusted” value takes into account the other resources. The values listed in the index are the adjusted values.

Note that the value of gems in the repeatable mines is ignored. There’s no good way to value them and their presence in a mine would distort the value of everything else in the mine.

There are no repeatable mines specifically for herbs, roots, apples, sugar or flour. Based roughly on caravan costs for those resources you get from the caravan and the value of other Egypt resources, these resources have been assigned a value of 10.

Forged items like bronze are undervalued because their values don't include the cost of the forging time but I don't know how to value that.

# Coins: 2

Repeatable Mine: Tutankhamun's Treasury
Energy cost: 1015 (-40 for the average 2 watermelons gained)
Average coins obtained: 502
Raw resource cost: 975 / 502 = 1.94
Other resources gained: 2 mushrooms
Adjusted energy cost: 975 - 2 * 12 (mushrooms) = 951
Adjusted resource cost: 951 / 502 = 1.89

Note: Higher level repeatable mines for coins have lower returns on energy. These are not considered here as most people past the start of the game have more coins then they need. Few people consider it worthwhile doing the higher level coin repeatables and we don’t want to over-value coins in calculating other resource values. Since coins are involved in every other calculation we'll round 1.89 to 2 to make things easier.
