Problem generating ores

[trulis]

I am using forge 3.1.26.387 and my ores are not generating. Here is the code

	public void generateSurface(World world, Random rand, int chunkX, int chunkZ)
{
	for(int i=0; i < 7; i++)
	{
		int randPosX = chunkX + rand.nextInt(16);
		int randPosY = rand.nextInt(46);
		int randPosZ = chunkZ + rand.nextInt(16);
		(new WorldGenMinable(cobaltOre.blockID, 4)).generate(world, rand, randPosX, randPosY, randPosZ);
	}
	for(int i=0; i < 7; i++)
	{
		int randPosX = chunkX + rand.nextInt(16);
		int randPosY = rand.nextInt(36);
		int randPosZ = chunkZ + rand.nextInt(16);
		(new WorldGenMinable(mithrilOre.blockID, 4)).generate(world, rand, randPosX, randPosY, randPosZ);
	}
	for(int i=0; i < 7; i++)
	{
		int randPosX = chunkX + rand.nextInt(16);
		int randPosY = rand.nextInt(26);
		int randPosZ = chunkZ + rand.nextInt(16);
		(new WorldGenMinable(adamantiteOre.blockID, 4)).generate(world, rand, randPosX, randPosY, randPosZ);
	}
}

Where is this code? In what class etc?

Make sure your code is actually run. {Do I even have to say this?}
