Remove Copper, Tin, bronze and Silver

[Vivacity]

I'm working on a modpack and I need to remove duplicate ores. Is there anyway I can completly remove Copper, Tin, Bronze and silver. Im running the latest version of Voltz mods on 1.5.2. I don't know where else to post this. I need help editing the config files. It would be greatly appreciated. All I've managed go do is stop silver ore from generating but it still exists.

Thanks guys for all your help. Without you I would have never become the person I am today.

Add the following lines to your Basic Components.cfg:

####################

# ore_generation

####################

 

ore_generation {

    B:"Generate oreCopper"=false

    B:"Generate oreTin"=false

}

Add the following lines to your electricexpansion.cfg:

####################

# ore_generation

####################

 

ore_generation {

    B:"Generate Silver Ore"=false

}
