Here I Have Done one Mod, you have a new biome and very news ores like steel, silver, whitegold, raritanium and ruby, some new foods and obsidian equipament! I'm Brasilian so if I wrote something wrong, Sorry!!
The ruby has almost no use, it's only to join with raritanium ingot and make a new supermaterial, all the equipaments are crafted equal all others equipament on minecraft, with exception from raritanium crystal pickaxe


People you have new foods too, you can make cheese with milk and bone meal, and you can make pizza with four cheeses, four breaads and one cooked porkchop, you can make salt with water bucket and bone meal, you can make raw bacon with salt and raw porckchop, and you can put it on furnace
To install this mod Requires Modloader, just install mod loader and put archives on /.minecraft/bin/minecraft.jar
You can install it with forge, but it is NOT recommended cause many textures are bugged.
To tell any bug, doubt or sugestion, just reply to this topic or send me an message

Here is a video from a friend of mine but he is brasilian too, so he doesn't speak English, only portuguese.
