Tine, bronze, silver ores

[ChopMan]

I can only seem to find vanilla minecraft ores outside of The Nether. In The Nether I have found Nether Tin ores and Nether Lead ores but although we have branched collectively for several hours on my server we have not found any tin or silver ores.

What elevation are you digging at? They might not be in the area you're branching in at all.

I tried both natural caves and different levels of branch-mining. There are 6-7 players on my server and none of them found any tin or silver outside Nether. There seems to only be vanilla ores outside The Nether.

EDIT: I also have a 60x60 quarry that doesn't find any other than Vanilla ores.

EDIT2: Never mind. I just figured it out. (started a vanilla server and switched to tekkit with the map already generated.)
