If GT correctly setuped and it supports that mods, then no new ores from mods, but GT will start generate own oredicted ores for that mods.
If GT does not support mods, then ores will generates.
But only in new chunks.
As I know, there is no charged certus quartz ores, but simple certus quartz will be generates in GT-ore veins.
TiC ore will also generates in ore veins.
