Stony Stone

This mod reduces the valuable metals produced by refining stone.

Basic Refinery and Refinery produces 10x less iron, nickel and silicon from stone.
Survival Kit values are unchanged.

Refining 1000 g of stone yields:
Above values are default (they are from a refinery without any modules installed).


I think that it is too easy to create large strip mines to get the basic metals from stone. This mod makes it far less profitable, while still allowing unlucky (or lazy ;) ) engineers to make due with stone, if they must.

There is another version, Extra Stony Stone, which also increases gravel production by an amount equal to the metal reduction.
