There are 8 new blocks. 4 Of them are just for crafting.
The other 4 -as the title said- creates ores.
These 4 new block's are: Iron Ore Generator, Coal Ore Generator, Gold Ore Generator and Diamond Ore Generator
They generate an ore every 0.5 seconds.
They generate the ores as item form so just put a hopper below it to collect it infinitly. That's it.
I did this mod for my server so I'm probably not gonna update it.
