There aren't any really different ways to get copper compared to tekkit classic. I don't have a perfect way, but a combination of the factorization ore processing and 64 by 64 quarries that stop once they leave the copper zone will result in a fair bit of copper. You could also make a Redpower horizontal boring machine that strips areas at the proper height, but those are very expensive and time consuming (and copper is one of the most used resources). Once your reactor is set up there's UU matter as well, but that isn't good for large quantities early on. Extreme Hills is a good place to mine, especially if you can fly, due to the many shallow exposed caves. (I assume you know (or can easly learn) most of this since you played tekkit classic). Mystcraft is also an option (if you are playing in SSP).

Also, thanks for helping out with the wiki.
