Concept very simple

All over maps you see :


Near Moutain/Hills
Tribes claim this mine and dig to find "nodes"


for Each Ore need specify Depth and curse Structure to support mine

Example :
Known Depth Range of Ores
Adomasite (301?) 490-922
Alferix 242-881
Azzurdite 450-827
Belkar 5m-1232m
Blaus 52m-1000m (9m reported elsewhere)
Caldorite 226m-998m
Cobalt 100-752
Copper 146-892
Cumbriz 164-992
Dianum 290-969
Durulium 280-1000
Erdorium 302-970
Erionite 379-710
Frigulite 90-855
Ganganite 165-1000m
Gazzurdite 138-1000m
Gold 560-1083m
Himi 131-671
Ignisium 230-814m
Iolite 596m-713
Iron 169-933m
Kanerium 357-1000
Kirtz 717-934m
Langotz 592-796
Lanorium 282m-733
Lysterium 6m-1000
Maganite 565-~900
Megan 245-842
Morpheus 821m-1000m
Narcanisum 95m-1000
Niksarium 231m-1025m
Petonium 544-650m
Platinum 696m-1000
Pyrite 476-1000m
Quantium 401-700
Redulite 870-1000
Rugaritz 758-980
Terrudite 700m-879
Tridenite 735m-~900
Valurite 739-1000m
Vesperdite 876-1000 (thx Skateboard T, Cyco)
Xeremite 740-1049 (thx cuga, cyco)
Zanderium 767-1000m (thx overburn)
Zinc 89-1000

Each more depth you dig more sink resources to repair ( i say sink and not massive sink )

Nodes are generate automicaly over 24h (not less because i think create massive CPU cost to this )
*better daily schudle (example df take one hour per day )

More rare you find , better tool you need , example you need picaxe or shovel reforceid gold to mine adomasite

------------------------------------------Each Area with your resource----------------------------------------------------
Concept same game above is each area have 3-6 resources , to make diversivty and curse miners chossen area like to mine and create trade above resources because craft use all , and not all area have all resources , create neede to buyit and sell (*damm my poor English)

* Hum i think need develop more idea about dig/tools
but i not paid for developer idea :P
