To obtain a Union Ore in Monster Hunter Freedom Unite (MHFU), you need to mine it from specific mining spots in the game, particularly in areas like the Mountain and the Volcano. Use a pickaxe to mine, and look for the shiny spots that indicate a mining location. Union Ore is a rare drop, so be prepared to mine multiple times to obtain it. Additionally, make sure you have enough pickaxes in your inventory before heading out.
You can find dragonite ore through mining level 3+ and mining in volcano land.
You can get it as the mining place +2 at your camp and at level 6 in the volcanic area if you mine there.
Bathycite ore is a higher rank or + item found in the flooded forest. You will need to be in an upper rank quest to ge it. I found it in areas: 1,4,5 and 8
easiest way is to go to pokke farm and mine it from the X mark by the east side of the farm.
In December 2008 an American version is being released, called Monster Hunter Union. I am not positive but I believe that there may be a way to import your save data from Freedom 2 into Union.

that would be Monster Hunter Freedom Unite on PSP and Monster Hunter Tri on Wii.
