I've got a github setup for the ores. You can watch progress
here. It shouldn't take but a few hours maximum due to how simple it is, but I don't think I can start work on it until tomorrow.
It'll be quite a lot of ore blocks: all metals using Moon Stone, all metals using Mars Stone, and all metals using Asteroid Stone (3). I'll do a select few gem ores, as well (Asteroid Quartz and Diamond). No generation properties, literally the most basic mod. I'll need to fish up all the oredictionary entries though.
