You can change:
The Ore Block (line 22) (You can add more, too)
The high where it start generating the ore (line 186 and line 188)
The function setTile2 (line 164), but this is not important, but, if you want, you can change what for blocks it replace with ore and what for blocks not
Copy - Paste the part where it generates ore (line 180 - ...) for more veines of one ore in one chunk and for other ores
Change the probability to generate one ore-vein (line 181)
