Miner Paradise

The spawning point is not too far away from a beautiful mining area. There are lots of iron, coal, gold and diamond to be found. (Over a hundred iron in an hour)
Hint: Bring ladders with you for when you fall down, or a lot of pickaxes.

Walkthrough
If you look at the picture, you'll see that there are 2 spots covered with Netherrack (red stuff). The upper-right location is the Spawning Point, en the Netherrack at the bottom-left is the entrance to the mine. So enter the mine.
Once you enter the mine, you can go 2 ways. You should take the path that leads away from the sand. After that, take an immediate right, and than again. You should now see 2 blocks of coal in the ground. If you don't read again. If you do, continue the road, and climb some kind of stairs. When you reach the wall, you'll see that there is 1 block missing. Mine through that spot, and a new path will open. Go through the hole and take the right path, and you'll see a huge gap. Go through the gap, but be careful because you can fall a long way. (Fall in the water, it should break your fall) Follow the stream, and you should see some light coming from lava. Ignore that and follow the road, and jump from another cliff, again in the water. You are now in a huge place with lots of coal, iron, gold an diamond. You probably don't see it right away, but just keep exploring.

Additional Notes

Please follow the instructions carefully. Also, if your PC is good enough, try to capture a video how to reach the 'paradise'.
