I wasn't having much luck either, until I stated a new mine in the Swamplands - I wanted to find Slimes.
But in 20 minutes I've found 14 diamonds, 105 Redstone, 22 Iron, 36 Lapis and 109 Coal.
Getting right back to it, only popped out to share the co-ords.
I started branch mining with a corridor North from -713 12.62 1806 (and so the branches go East and West).
